find the greatest common factor of the following monomials 3B + 30 B

Answer:

a1 = 2; an = a(n-1) + 3/2

Step-by-step explanation:

Common difference = 7/2 - 2

= 7/2 - 4/2

= 3/2  

(Also 5 - 7/2 = 3/2.)

First term a1 = 2

So the formula is  a1 = 2; an = a(n-1) + 3/2 which is the first choice.

The recursive formula for the arithmatic sequence is a₁ = 2, aⁿ = aⁿ⁻¹ + 3/2.

A recursive formula is a formula that defines any tern of a sequence in terms ofits preceding term(s).

Now the given series is-

2,7/2,5,13/2,......

Here the the first term of the series is 2

⇒a₁ = 2

Common difference (d) = (7/2) - 2 = 3/2

Now the recursive formula of an arithmatic sequence is given as,

aⁿ = aⁿ⁻¹ + d

Putting the values,

aⁿ = aⁿ⁻¹ + 3/2

Hence,the recursive formula for the arithmatic sequence is a₁ = 2, aⁿ = aⁿ⁻¹ + 3/2.

Answer:

16 1/2, or 16.5 square meters

Step-by-step explanation:

This is a simple explanation, scroll down for the details on how I got to this answer!

Step 1. Find the rate at which Rachel can paint.

(5 1/2 square meters per 1/3 hour)

Step 2. Find the area of wall space Rachel can paint in 1 hour, using this rate.

5 1/2 × 3 = 16 1/2 or 16.5 square meters

1/3 × 3 = 1 hour

Rachel can paint 16 1/2 square meters of wall space in 1 hour.

**How I solved this problem**

Step 1. To find the area of wall space Rachel can paint in 1 hour, we need to find a rate that shows her speed (square meters/hours).

In the first sentence, we are given a rate:

"5 1/2 square meters of wall space in 1/3 hour."

This can be modeled by the fraction: [tex]\frac{5\frac{1}{2} }{\frac{1}{3} }[/tex]

Step 2. To find how much she can paint in 1 hour, we can multiply this rate by 3. This is because the rate tells us that the area of wall space Rachel can paint in 1/3 hour.

Remember, to cancel out a fraction, multiply by its reciprocal, which is the fraction "flipped" (the numerator and denominator switch). We multiply 1/3 by 3/1 (3) because it is 1/3 flipped.

Since Rachel is painting at a constant rate of 5 1/2 square meters per 1/3 hour, we also need to multiply the other part of the fraction by 3, so the rate stays the same.

5 1/2 × 3 = 16 1/2 or 16.5 square meters

1/3 × 3 = 1 hour

This is our final answer: Rachel can paint 16 1/2 square meters of wall space in 1 hour.

Rachel can paint 16 1/2 square meters of wall space in one hour by multiplying her painting rate for 1/3 hour by 3.

Rachel paints 5 1/2 square meters of wall space in 1/3 hour. To determine the area she can paint in one hour, we need to use the concept of unit rate, which is the amount of work done per unit of time.

To find Rachel's painting rate in square meters per hour, we can set up a proportion. Since we want to find out how much she can paint in one full hour, we multiply the area she can paint in 1/3 of an hour by the reciprocal of 1/3 (which is 3) to calculate the full hour painting area.

So, Rachel's painting rate per hour is 5 1/2 * 3 square meters. Multiplying, we get (5 + 1/2) * 3 = (11/2) * 3 = 33/2 = 16 1/2 square meters. This is the area she can paint in one hour.

Answer: x=72, y=26

Step-by-step explanation:

Since a line is 180°, we can do:

2x+10+y=180

2x+y=170

Since a triangle is 180° also, we can do:

x+y+82=180

x+y=98

If we subtract x+y=98 from 2x+y=170, we get:

2x+y=170

x+y=98

x=72

If we insert x=72 into x+y=98, we get:

72+y=98

y=26

We can check our answer by inserting x=72 and y=26 into x+y+82=180

72+26+82=180

98+82=180

180=180

Cindy's reading rate is consistent at 1.25 pages per minute, which is the constant of proportionality for the different reading sessions mentioned.

The question is asking for the constant of proportionality in the context of how many pages Cindy can read over a period of time. To find the constant of proportionality, we take the number of pages read and divide it by the time taken to read those pages. For 10 pages in 8 minutes, the constant is 1.25 pages per minute. For 15 pages in 12 minutes, the constant is also 1.25 pages per minute, and for 25 pages in 20 minutes, the constant remains unchanged at 1.25 pages per minute.

The constant of proportionality is the rate at which Cindy reads, which is consistent across the different amounts of time and pages given. It represents the number of pages she can read in one minute and serves as a useful measure to determine how long it will take to read a certain number of pages or how many pages can be read in a given timeframe.

Answer:

Step-by-step explanation:

the sum to n terms of an arithmetic sequence is

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex][2a + (n - 1)d ]

where d is the common difference and a is the first term

here d = 9 - 7 = 7 - 5 = 2 and a = 5, hence

[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex][(2 × 5) + 2(n - 1) ]

                        = [tex]\frac{n}{2}[/tex](10 + 2n - 2)

                        = [tex]\frac{n}{2}[/tex](2n + 8)

                        = n² + 4n

When sum = 165, then

n² + 4n = 165 ← rearrange into standard form

n² + 4n - 165 = 0 ← in standard form

(n + 15)(n - 11) = 0 ← in factored form

equate each factor to zero and solve for n

n + 15 = 0 ⇒ n = - 15

n - 11 = 0 ⇒ n = 11

but n > 0 ⇒ n = 11

The sum of n terms for the arithmetic series is:

[tex]S_n=\frac{n}{2}[8+2n ][/tex]

The value of n for which the series has sum 165 is 11

The given series is:

5 + 7 + 9 +.......

The first value, a = 5

The common difference, d = 7 - 5

d  =  2

The sum of the first n terms of an arithmetic series is given by the formula:

[tex]S_n=\frac{n}{2}[2a+(n-1)d ][/tex]

Substituting a = 5, and d = 2 into the sum of the series, we have:

[tex]S_n=\frac{n}{2}[2(5)+(n-1)(2) ]\\\\S_n=\frac{n}{2}[10+2n-2 ]\\\\S_n=\frac{n}{2}[8+2n ][/tex]

To determine the value of n for which the series has sum 165, substitute [tex]S_n=165[/tex] into the sum above

[tex]S_n=\frac{n}{2}[8+2n ]\\\\165=\frac{n}{2}[8+2n ]\\\\2(165)=n(8+2n)\\\\2n^2+8n-330=0\\\\n^2+4n-165=0\\\\n^2-11n+15n-165=0\\\\n(n-11)+15(n-11)=0\\\\(n-11)(n+15)=0\\\\n=11, n=-15[/tex]

Answer:

Given: If triangle CFH is similar to triangle TDM with a scale factor of 4: 5.

Similar triangle states that the two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

then by definition, we have;

[tex]\frac{CF}{TD}= \frac{FH}{DM} =\frac{CH}{TM}= \frac{4}{5}[/tex]  .....[1]

From the figure, we have;

CF = x +7 , FH = x-1 , CH = x+3 , TD = 2x -13 , DM = x+6 and TM = x+ 11

Solve for x;

[1] ⇒ [tex]\frac{CF}{TD} =\frac{4}{5}[/tex]

Substitute the value of CF and TD to solve for x;

[tex]\frac{x+7}{2x-13} = \frac{4}{5}[/tex]

By cross multiply we get;

[tex]5 (x+7) = 4(2x-13)[/tex]

Using distributive property : [tex]a\cdot(b+c) = a\cdot b + a\cdot c[/tex]

5x + 35 = 8x - 52

Subtract 35 on both sides we get;

5x + 35 -35 = 8x - 52 -35

Simplify:

5x = 8x - 87

Subtract 8x on both sides we get;

5x -8x = 8x -87 -8x

Simplify:

-3x = -87

Divide both sides by -3 we get;

x = 29

To find the perimeter of triangle CFH;

Sides are:

CF = x + 7 = 29 + 7 = 36 units

CH = x+3 = 29 +3 = 32 units

FH = x -1 = 29 -1 = 28 cm.

Perimeter of any triangle is the sum of all the sides of the triangle.

Perimeter of triangle CFH = CF + CH + FH = 36 + 32 + 28 = 96 units

therefore, the perimeter of triangle CFH is, 96 units.

Without the perimeter of triangle TDM, we can't calculate the perimeter of triangle CFH using only the scale factor. When additional information is provided such as the length of a side in both triangles, it will be possible.

The subject of this question is mathematics, specifically regarding similar triangles and the calculation of a triangle's perimeter when the scale factor is provided. In this case, the triangles CFH and TDM are similar with a scale factor of 4:5.

When triangles are similar, corresponding sides are proportional which means one side of triangle CFH is 4/5 the length of the corresponding side of triangle TDM. If we were given the perimeter of triangle TDM, we would multiply by the ratio (4/5 or 0.8) to get the perimeter of triangle CFH. However, without this extra information, we aren't able to provide the exact perimeter of triangle CFH.

Answer:

The volume of a cube whose total surface area is 150 sq. ft. is 125 cubic feet.

Step-by-step explanation:

Set up an equation that shows the relation between the side length L of the cube and its surface S:

[tex]S = 6\cdot L^2\\150 = 6\cdot L^2\implies\\|L| = \sqrt{\frac{150}{6}}= 5[/tex]

The side length of a cube with an area of 150 sq. ft is 5 ft. Now we can easily calculate the volume V:

[tex]V = L^3 = 5^3 = 125[/tex]

The volume of a cube whose total surface area is 150 sq. ft. is 125 cubic feet.

The volume of a cube with a total surface area of 150 square feet is 125 cubic feet. This is found by first dividing the total surface area by 6 to find the area of one face, then taking the square root to find the length of one side, and finally cubing this length.

To find the volume of a cube when you know the total surface area, you begin by realizing that a cube has six identical faces. Hence, the surface area of one face is the total surface area divided by 6. In this case, 150 square feet divided by 6 equals 25 square feet. This is the area of one face. Because this is a cube, the length, width, and height are equal, so the square root of 25 (which is 5) would give us the length of one side.

Now, the volume of a cube is the side length cubed. Hence, in this case, the volume would be 5 feet (the length of a side) cubed, or 5 * 5 * 5, which equals 125 cubic feet.

The change in low outside temperature from Tuesday to Wednesday was -1.4°C, indicating a decrease of 1.4°C. Converting 88°F to Celsius yields approximately 31.1°C. The Celsius scale is known as 'centigrade' due to its 100-degree division between water's freezing and boiling points.

To solve for the change in low outside temperature from Tuesday to Wednesday, we subtract the low temperature for Wednesday from the low temperature for Tuesday:

Change in temperature = Temperature on Wednesday - Temperature on Tuesday

Change in temperature = (-10°C) - (-8.6°C)

Change in temperature = -10°C + 8.6°C = -1.4°C

Thus, the low outside temperature changed by -1.4°C from Tuesday to Wednesday, which means it dropped by 1.4°C.

1. To convert the temperature from Fahrenheit to Celsius:
C = (°F - 32) / 1.8. So on a warm day of 88°F:
C = (88°F - 32) / 1.8 = 56°F / 1.8 = 31.1°C approximately.

2. The Celsius scale is called "centigrade" because it is based on a scale of 100 degrees between the freezing and boiling points of water.

3. If the outside temperature is steady at 10°C and you want to maintain a shorts-and-short-sleeves comfortable inside temperature of 22°C compared to a cooler 13°C, you would need to expend more energy to maintain the higher temperature.

The difference in energy required will depend on factors like the insulation of the building, the heating system's efficiency, and the duration for which the higher temperature is maintained.

4. When a cold front causes a drop of 40.0°F:
Celsius decrease = 40.0°F / 1.8 = 22.2°C approximately.

5. Any change in temperature in Fahrenheit degrees is nine-fifths the change in Celsius degrees:
(Change in °F) * (5/9) = Change in °C
Thus, a change in Fahrenheit degrees is 9/5 times a change in Celsius degrees.

The correct answer is -1.4⁰.

To find the change in the low outside temperature from Tuesday to Wednesday, we need to subtract the temperature on Tuesday from the temperature on Wednesday.

The temperature on Tuesday is -8.6 degrees Celsius, and the temperature on Wednesday is -10 degrees Celsius.

To subtract -8.6 from -10, we can rewrite the equation as -10 - (-8.6). When we subtract a negative number, it is the same as adding the positive number. So, -10 - (-8.6) becomes -10 + 8.6.

When we add -10 and 8.6, we get -1.4.

Therefore, the change in the low outside temperature from Tuesday to Wednesday is -1.4 degrees Celsius.

So the correct answer is -1.4⁰.

p → q

Where:

p and q represent sentences or statements.

Generally speaking, two expressions are considered as being logically equivalent if they have the same truth value for all possible combinations of truth values and for all variables that appear in both expressions.

This conditional statement ~p → q means if not p, then q;

where:

The expression 4(x-5) + 2(y+6) - 10 simplifies to 4x + 2y - 18 using the distributive property and combining like terms. Answer choice (A) is the correct one.

To simplify the expression 4(x - 5) + 2(y + 6) - 10, you need to use the distributive property. This property allows you to multiply a number outside of a bracket with each term inside the bracket.

First, distribute 4 into (x - 5) which gives you 4x - 20. Then distribute 2 into (y + 6) which gives you 2y + 12. Now, you have 4x - 20 + 2y + 12 - 10

Combine like terms by adding or subtracting them. In this case, -20, +12 and -10 are like terms. When you add these together, you get -18. So, the simplified expression becomes 4x + 2y - 18. Therefore, answer choice (A) is correct.

To solve this problem, we must first find the fraction of action figures that Lee has gotten so far.  To do this, we will represent the number of action figures that Lee currently has in the numerator divided by the denominator, the total number of action figures that Lee is attempting to collect.

First, we must recognize that Lee currently has 11 action figures plus the 3 that he got for his birthday.  To find the total number of action figures that Lee has, we must add together these two parts.  

11+3 = 14

Therefore, Lee has 14 action figures (this will become the numerator of the fraction).  The denominator of the fraction is the total number of action figures, which we are given is 22.

Thus, our fraction is 14/22.

To convert this into a decimal, we can simply divide the numerator of the fraction by the denominator of the fraction, which gives us:

14/22 = 0.636363636

Therefore, your answer is approximately 0.636.

Answer : The correct option is, (D) [tex]\frac{2}{5}[/tex]

Step-by-step explanation :

Probability : It is defined as the extent to which an event is likely to occur. That means, it is measured by the ratio of the favorable outcomes to the total number of possible outcomes.

[tex]\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of favorable outcomes}}[/tex]

Total favorable outcomes are, 2 broccoli, 2 cake, 2 carrot, 1 chicken, 2 fish, and 1 meat loaf = 10

Favorable outcomes of choosing a vegetable are, 2 broccoli and 2 carrot

Number of favorable outcomes of choosing a vegetable = 4

Total number of outcomes = 10

[tex]\text{Probability}=\frac{\text{Number of favorable outcomes for a multiple of 3}}{\text{Total number of favorable outcomes}}[/tex]

[tex]\text{Probability}=\frac{4}{10}[/tex]
