Find the greatest common factor of the
following monomials:
15x4y6 6x5y?
12x3, 4

Answer:

-15

Step-by-step explanation:

the y-intercept would be -15

Answer:

x = - 5, x = 3

Step-by-step explanation:

To find the x- intercepts let y = 0, that is

x² + 2x - 15 = 0

Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)

The factors are + 5 and - 3, since

5 × - 3 = - 15 and 5 - 3 = + 2, hence

(x + 5)(x - 3) = 0

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

x - 3 = 0 ⇒ x = 3

x- intercepts at (- 5, 0) and (3, 0)

Answer:

16 : 25

Step-by-step explanation:

The ratio of girls : boys = 320 : 500

To simplify divide both parts by 10

320 : 500 = 32 : 50 ← now divide both parts by 2

32 : 50 = 16 : 25 ← in simplest form

Final answer:

To calculate the simplified ratio of the number of girls to the number of boys in the school, we divide the numbers 320 (girls) and 500 (boys) by their greatest common divisor, which is 80, resulting in the simplest form of 4:6.25 or 16:25.

Explanation:

The question is asking us to find the ratio of the number of girls to the number of boys in a school, and then to simplify this ratio to its simplest form. There are 320 girls and 500 boys in the school. To find the ratio, we compare the number of girls to the number of boys, which gives us 320 to 500.

To simplify the ratio, we look for the greatest common divisor (GCD) that both numbers share. Both 320 and 500 are divisible by 10 for certain, and further simplification can be found by dividing by the GCD of 80. So, if we divide both numbers by 80, we get 4 to 6.25, which simplifies further to a ratio of 4:6.25 or 16:25 when both sides are multiplied by 4. Therefore, the simplified ratio of the number of girls to the number of boys is 16:25.

In order to add the equations, the left hand side of one equation will be added to the left hand side of second equation. similarly, the right hand side of first equation will be added to the right hand side of the equation so,

[tex]x+6y+(-x+2y)=9+(-15)\\Combining\ alike\ terms\\x+6y-x+2y=9-15\\6y+2y=-6\\8y=-6\\Can\ also\ be\ written \ as\\4y=-3[/tex]

Answer:

The resultant equation is 8y = -6

Step-by-step explanation:

To get the system of equation that will results from adding the statement, we will follow the steps below;

x+6y=9 -------------------------------------------------------------------------------(1)

-x+2y=-15-------------------------------------------------------------------------------(2)

Adding equation (1) and equation(2), we will have;

(1-1)x + (6+2)y =(9-15)

Final answer:

To convert 27 feet to inches, multiply 27 by the conversion factor of 12 inches per foot, resulting in 324 inches.

Explanation:

To convert 27 feet to inches, we use the unit equivalence that 1 foot = 12 inches. We multiply the number of feet by the conversion factor to get the measurement in inches.

27 feet × 12 inches/foot = 324 inches.

Therefore, 27 feet is equivalent to 324 inches. This is a straightforward application of unit conversion, which is a fundamental skill in mathematics, especially useful for various applications in science, engineering, and everyday calculations.

Answer:

73 m is equal to 730 dm

Step-by-step explanation:

We Need to convert 73 m into dm

We know that 1 meter is equal to 10 decimeter

We are given 73 m. Multiply it with 10 and we will get value in decimeter

73*10

= 730 decimeter

So, 73 m is equal to 730 dm

Answer:

The correct answer would be 730 dm.

Step-by-step explanation:

M is the abbreviation of Meter and dm is an abbreviation of Decimeter. A meter is a unit of length as prescribed by the international system of units. This unit is used to measure the length. Decimeter is the smaller unit of meter. 10 Decimeter makes one meter, which means 1M equals 10DM. So where there are 73 meters, there would be 73 * 10 Decimeters in it. This is shown as below.

73 m = 73 * 10 = 730 DM

to get the slope of it, we simply need two points off the table, say (-4,-114) and (2,48).  Recall that the y-intercept, where the graph intercepts the y-axis, when that happens x = 0, so is right there on the table already.

Answer: Third Option

[tex]V = 200.96\ in^3[/tex]

Step-by-step explanation:

By definition, the volume of a cone is:

[tex]V = \frac{1}{3}\pi r^2h[/tex]

V is the volume of the cone

h is the height of the cone

r is the radius of the cone

In this case we know that:

[tex]r= 4\ in\\h= 1\ ft[/tex]

We know that in 1 ft there are 12 inches

So

[tex]h=12\ in[/tex]

Now substitute the values of h and r in the formula to obtain the volume of the cone

[tex]V = \frac{1}{3}\pi (4)^2(12)[/tex]

[tex]V = 16*4\pi[/tex]

[tex]V = 200.96\ in^3[/tex]

Answer:

c

Step-by-step explanation:

Divide using synthetic division, remembering to place a zero to denote the terms x³, x² and x

Since division by (x - 3) then evaluate using h = 3

3 | 1  0  0  0  7

    ↓

    1    3  9  27 81

   ----------------------

    1  3  9  27  88 ← degree 3 polynomial

quotient = x³ + 3x² + 9x + 27 , remainder = 88 → c

Follow below steps:

To divide x^4 + 7 by x - 3, we will use polynomial long division. This process is similar to the long division we use with numbers. Let's perform the division step by step:

Divide the term with the highest power in the dividend (x^4) by the highest power in the divisor (x) to get x^3.

Multiply the entire divisor by x^3 and subtract the result from the dividend.

The subtraction will give a new polynomial. Repeat the process until the degree of the remainder is less than the degree of the divisor, or until no further division can be carried out.

The correct result for the division of x^4 + 7 by x - 3 is option (a): x^3 - 3x^2 - 9x - 27 R 88.

Answer:

x = 19°

Step-by-step explanation:

Let The angle be "a"

Now according to the question,

⇒ 3 × a = (90° - a) - 14° (Then remove the brackets)

⇒ 3a =  90° - a - 14°

⇒ 3 + a = 76°

⇒ 40° = 76°

⇒ a = 76/4

Now since you got 76/4 you have to make it into simplest form so it'll be :

Answer:

Top Right

Step-by-step explanation:

First things first, you can eliminate the bottom left option. The domain 3≤x≤6 means that the graph will only show points greater than or equal to 3 and less than or equal to 6. That option shows x = 2, which is not in this domain.

The symbols on either side of the x are known as ceiling functions. It means that y equals whatever whole number is greater than or equal to than x.

Basically, whatever y is, round it up to the nearest whole number to get x.

So, let's do a table from x = 3 to x = 6

   x ║ y               Now, see which graph best matches these

2.5 ║ 3               coordinates. Keep in mind that to be a function,

  3 ║ 3                the points cannot overlap (they have to pass the

Answer:

a) Current Interest is $75.8

b) the final payment will be $11,830

Step-by-step explanation:

Principal Amount = $9,100

Interest rate = 10% or 0.1

Time = 36 months = 3 yeras

Balance after 27 payments = $2,526.85

a) What is the CURRENT month's interest?

The formula to find interest is:

Interest = P*r*t

P= Principal

r = Interest rate

t = time in years

Interest = 9100*0.1*3

Total Interest = 2730

As total period is 36 months so, divide total interest by 36

Current Month Interest = 2730/36

Current Month Interest = 75.8

So, current month interest is $75.8

b) What is the final payment?

The formula used will be

A = P(1+r*t)

A = Final amount

r = interest rate

t = time

Putting values:

A = P(1+r*t)

A = 9100*(1+0.1*3)

A = 9100*(1.3)

A = 11,830

So, the final payment will be $11,830

Answer: [tex]65.44\ in^3[/tex]

Step-by-step explanation:

To calculate the volume of a cone you can use this formula:

[tex]V_{(cone)}=\frac{1}{3}\pi r^2h[/tex]

Where "r" is the radius and "h" is the height of the cone.

In this case you know that this cone has a height of 2.5 inches and a radius of 5 inches. Then:

[tex]h=2.5\ in\\r=5\ in[/tex]

Finally, you need to substitute these values into the formula. Then you get that the volume of the cone is:

 [tex]V_{(cone)}=\frac{1}{3}\pi (5\ in)^2(2.5\ in)\\\\V_{(cone)}=65.44\ in^3[/tex]
