What is the product of −225 and −356 ? −915 −6730 613 ​ 915 ​

Answer:x=20

Step-by-step explanation:

2(3x+1) = 6x+2

since xy and yz are the parts of a midpoint they are equal to eachother

so 6x+2=5x+22

if you subtract 5x from both sides you get x+2 = 22 then you subtract 2 from both sides so you have x=20

Answer:

see explanation

Step-by-step explanation:

given x² - 6x - 21 = 0 ( add 21 to both sides )

x² - 6x = 21

to complete the square

• add ( half the coefficient of the x-term)² to both sides

x² + 2 (- 3)x +9 = 21 + 9

(x - 3)² = 30 ( take the square root of both sides )

x - 3 = ± [tex]\sqrt{30}[/tex] ( add 3 to both sides )

x = 3 ± [tex]\sqrt{30}[/tex]

x = 3 - [tex]\sqrt{30}[/tex] = - 2.48 ( to 2 dec. places ) or

x = 3 + [tex]\sqrt{30}[/tex] = 8.48 ( to 2 dec. places )

Answer:

x = - 3 and x = - 4

Step-by-step explanation:

(a)

The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be.

solve x + 3 = 0 ⇒ x = - 3

(b)

Equate f(x) to 5, that is

[tex]\frac{2x+3}{x+3}[/tex] = 5 ( cross- multiply )

5(x + 3) = 2x + 3 ( distribute left side )

5x + 15 = 2x + 3 ( subtract 2x from both sides )

3x + 15 = 3 ( subtract 15 from both sides )

3x = - 12 ( divide both sides by 3 )

x = - 4

Answer:

[tex]5\frac{23}{64}\approx 5.36 [/tex] cubic meters.

Step-by-step explanation:

We have been given that the surface area of a cube is [tex]18\frac{3}{8}[/tex] square meters and we are asked to find the volume of the cube.

Since we know that surface area of a cube with each edge equals a units is:

[tex]\text{Total surface area of cube}=6a^2[/tex]

Let us find length of each edge using surface area formula.

[tex]18\frac{3}{8}=6a^2[/tex]

Let us convert our given area into mixed fraction.

[tex]\frac{147}{8}=6a^2[/tex]

Upon dividing both sides of our equation by 6 we will get,

[tex]\frac{147}{8*6}=a^2[/tex]

[tex]\frac{147}{48}=a^2[/tex]  

Upon taking square root of both sides we will get,

[tex]\frac{7\sqrt{3}}{4\sqrt{3}}=a[/tex]  

[tex]\frac{7}{4}=a[/tex]

Now we will use volume of cube formula with each side length 'a'.

[tex]\text{Volume of cube}=a^3[/tex]

[tex]\text{Volume of cube}=(\frac{7}{4})^3[/tex]

[tex]\text{Volume of cube}=\frac{343}{64}[/tex]

[tex]\text{Volume of cube}=5\frac{23}{64}[/tex]

[tex]\text{Volume of cube}=5.359375\approx 5.36[/tex]

Therefore, the volume of cube will be [tex]5\frac{23}{64}[/tex] cubic meters.

The correct answer option is A. x2 – 3x + 15.

Step-by-step explanation:

We are given the following expression and we are supposed to simplify it:

[tex]7x^2+6x-9x-6x^2+15[/tex]

Before solving it, a good idea will be to arrange all the like terms together in their decreasing power and write the expression as:

[tex]7x^2-6x^2+6x-9x+15[/tex]

Simplifying it to get:

[tex]x^2-3x+15[/tex]

Therefore, the first option A is the correct answer x2 – 3x + 15.

Answer:

A. [tex]x^{2} - 3x +15[/tex]

The cups of sugar mario use would be  16 3/8 cup

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that Mario made six batches of cookies. His friends asked him to make an extra batch.

He used 15 3/4 cups of sugar

15 3/4 cup = 126/8 cup

then he needs another 5/8 cup for the extra batch.

126/8 + 5/8 = 131/8 cup

Mario use altogether;

131/8 = 16 3/8 cup

Answer:

Linear  

Step-by-step explanation:

Each time x increases by one unit, y increases by three units.

The table represents a linear function of x.

With a principal of $5,000, an interest rate of 3.8%, over 22 years, Jackson's principal will grow to $11,535

Given: principal is $5000, interest rate is 3.8% and it is compounded continuously

To find: amount when Jackson is 40 years old

To solve this problem, we use the formula for continuous compounding interest:

[tex]A = P \times e^{rt}[/tex]

where:

A is the total amount of money

P is the principal

r is the annual interest rate (decimal form, so 3.8% becomes 0.038)

t is the time in years

Time here will be 22 years as Jackson deposited the money when he was 18 years old. So, the difference of 40 and 18 gives us 22 years.

Now we can find the total amount by plugging in the values:

[tex]A = 5000 \times e^{0.038 \times 22}\\[/tex]

[tex]A= 5000 \times e^{0.836}\\[/tex]

[tex]A= 5000 \times 2.307\\[/tex]

[tex]A = 11535[/tex]

Therefore, Jackson's account will have $11,535 when he is 40 years old.

Answer:

∠CAT = 140°

Step-by-step explanation:

Since AB bisects ∠CAT then ∠BAT = ∠CAB, hence

5x + 20 = 2x + 50 ( subtract 2x from both sides )

3x + 20 = 50 ( subtract 20 from both sides )

3x = 30 ( divide both sides by 3 )

x = 10

∠CAT = ∠BAT + ∠CAB = 5x + 20 + 2x + 50 = 7x + 70

substitute x = 10 into the expression

∠CAT = (7 × 10) + 70 = 70 + 70 = 140°

then you multiply the denominator with denominato and numerator with numerator, so the answer is 1/6

Hello There!

To multiply fractions, you first want to line up the numerator and the denominator together so they line up with each other.

Next, you want to multiply across. This includes multiplying the numerators together and then multiplying the denominators together.

Finally, you want to find the greatest common factor but only if the fraction can be simplified.

Final answer:

To find the measure of angle K in the isosceles trapezoid JKLM, set the expressions for angle J and angle M equal to each other and solve for x. Substituting the value of x into one of the angle expressions will give the measure of angle K.

Explanation:

To find the measure of angle K in the isosceles trapezoid JKLM, we can use the fact that the opposite angles in an isosceles trapezoid are congruent. Since angle J and angle M are given in terms of x, we can set them equal to each other and solve for x:

17x + 7 = 11x + 13

Simplifying the equation, we get:

6x = 6

x = 1

Now that we have the value of x, we can substitute it back into one of the angle expressions to find the measure of angle K:

m∠K = 17(1) + 7 = 24 degrees

[tex]\frac{4}{10}(-\frac{1}{4} c+1)[/tex]

Step-by-step explanation:

To factor the expression [tex]\frac{-4}{40}c+\frac{12}{30}[/tex] we use the GCF or greatest common factor. The greatest common factor is the greatest number that will divide into the values. We start to find it by factoring each term's coefficient:

[tex]\frac{2*2}{2*2*2*5}[/tex]

[tex]\frac{2*2*3}{2*3*5}[/tex]

We notice both have 2*2 in the numerator and 2*5 in the denominator. This is our GCF.

[tex]\frac{2*2}{2*5}=\frac{4}{10}[/tex]

We now write the expression 4/10(____+_____). We find the inside of the parenthesis by dividing the coefficients by the GCF. This is also the remaining factors which are not part of the GCF.

[tex]\frac{1}{2*2}=\frac{1}{4}[/tex]

[tex]\frac{3}{3}=1[/tex]

So the answer is [tex]\frac{4}{10}(-\frac{1}{4} c+1)[/tex]

Answer:

the answer is 44

Step-by-step explanation:

the pattern is 4,5,6,7,8 so then you would add 9 to get 44

Final answer:

The pattern in the given list of numbers is that each number increases by consecutively larger increments of 1. By continuing this pattern, adding 9 to the last number (35), we determine the next number in the series to be 44.

Explanation:

The given list of numbers is 5, 9, 14, 20, 27, 35, and we are asked to identify the pattern to find the next number in the series.

Let's look at the differences between consecutive terms: 9 - 5 = 4, 14 - 9 = 5, 20 - 14 = 6, 27 - 20 = 7, 35 - 27 = 8.

We can see that with each step, the difference increases by 1. This pattern suggests that the next difference should be 9.

To find the next number, we add 9 to the last number in the series: 35 + 9 = 44. Therefore, the next number in the series is 44.

Answer:

Since you want me to answer 3 lb 1 oz - 1 lb 15 oz instead, the answer is 18 oz

Step-by-step explanation:

First, convert pounds and ounces to just ounces, then subtract the total ounces. Finally, convert back to pounds and ounces to get the result of 8 lb 1 oz minus 3 lb 6 oz, which is 4 lb 11 oz.

Subtracting Mixed Measurements

To find the result of 8 lb 1 oz − 3 lb 6 oz, follow these steps:

Convert everything to ounces for easier subtraction (since there are 16 ounces in a pound).

Subtract the ounces first, then subtract the pounds.

Step-by-Step Solution

Step 1: Convert to ounces
8 lb 1 oz = (8 × 16) + 1 = 128 + 1 = 129 ounces
3 lb 6 oz = (3 × 16) + 6 = 48 + 6 = 54 ounces

Step 2: Subtract the ounces
129 ounces - 54 ounces = 75 ounces

Step 3: Convert back to pounds and ounces
75 ounces = 4 lb 11 oz (since 75 ÷ 16 = 4 remainder 11)

Therefore, 8 lb 1 oz − 3 lb 6 oz = 4 lb 11 oz.

Answer:

30% of the meat on the platter is ham.

Step-by-step explanation:

90 slices = 100%

10% = 9 slices

90 - 63 = 27 slices (this is the amount of ham)

10% x 3 = 30% = 27 slices of ham

Answer:

27 slices of ham which is about 30% of the meat.

Step-by-step explanation:

In this problem we have given

no. of slices of meat=90

no of slices of turkey's meat=63

Percent of ham in platter=?

No of ham slices= Total slices -turkey slices

=90 - 63

= 27 slices

therefore no of ham slices=27

percent of ham slices=Ham slicesx100/total slices

=27x100/90%

=30%

Therefore  percent of ham's in patter=30%

Step-by-step explanation:

larger number = y

smaller number=x

y>2x+1

y<3x+6

Probably the first one, if I did this right.

To do this problem, you need to know how to read math, literally. The problem says that y is the larger number, so assume the smaller is x. So, y exceeds 2x by 1 (so, y>2x+1). then, it says 3x exceeds y by 6; therefore, 3x+6>y. I may have interpreted it wrong, though, so tell me if I made a mistake :))

Answer:

first one

A. y = 2x + 1 and 3x + 6 = y
