There are 90 yellow flowers, 54 red flowers, and 36 white flowers for centerpieces. If the flowers need to be divided equally into separate centerpieces with the same number of each color of flower in each centerpiece, how many different centerpieces will there be?

Answers

Answer:

You can create the fewest centerpieces for the smallest number of any color, which is 2 centerpieces using the white flowers. Therefore, you will have 2 centerpieces with an equal number of each color of flower in each centerpiece.

Step-by-step explanation:

First, find the GCD of 90, 54, and 36:

Find the GCD of 90 and 54:

GCD(90, 54) = 18

Find the GCD of the result (18) and 36:

GCD(18, 36) = 18

So, the GCD of 90, 54, and 36 is 18.

Now, you can create centerpieces with 18 flowers of each color (yellow, red, and white) in each centerpiece. To find out how many centerpieces you can create, divide the total number of each color by 18:

Number of yellow flowers / 18 = 90 / 18 = 5 centerpieces

Number of red flowers / 18 = 54 / 18 = 3 centerpieces

Number of white flowers / 18 = 36 / 18 = 2 centerpieces

You can create the fewest centerpieces for the smallest number of any color, which is 2 centerpieces using the white flowers. Therefore, you will have 2 centerpieces with an equal number of each color of flower in each centerpiece.

x - 3 is a factor of P(x) = x^3 – 7x² +15x-9
A. True
B. False

Answers

A. True
Explanation-

Let p(x) = x^3 – 7x^2 – 15x – 9

For checking that (x – 3) is a factor of p(x), we find : p(3)

p(3) = (3)^3 – 7(3)^2 + 15(3) – 9

= 27 – 63 + 45 – 9

= 72 – 72

= 0

Hence, (x – 3) is a factor of p(x).

By division of p(x) by x – 3, we get the quotient

= x^2 – 4x + 3

∴ x^3 – 7x^2 + 15x – 9

= (x – 3)(x^2 – 4x + 3)

= (x – 3)(x – 3)(x – 1)

= (x – 3)^2(x – 1)

If x and y are integers, and 3x + 2y = 13, which of the following could be the value of y ?A. 0
B. 1
C. 2
D. 3
E. 4

Answers

They are all integers so...
first lets substitute
A.3x=13
X=13/3
b.3x+2=13
3x=11
x=11/3
c.3x+4=13
3x=9
x=3
d.3x+6=13
3x=7
x=7/3

E.3x+8=13
3x=5
x=5/3

therefore the possible is letter c because it must be an integer and the definition of integer states that it is not a decimal nor a fraction
C. 2
Because
3x+2(2)=13
3x+4=13
3x=9
x=3

None of the other solutions work out so that both x and y are integers.

5. If you earn $8 per hour after taxes are taken out of your paycheck and your insurance is $200 a month, how many hours will you have to work to pay for insurance?

Answers

so 8 times x hours=200
8x=200
divide both sides by 8
x=200/8
x=100/4
x=25
you have to work 25 hours
200÷8= 25
If you earn $8 per hour after taxes are taken out of your paycheck and your insurance is $200 a month, you would have to work 25 hours would have to be worked to pay for insurance.

each month for 6 months, Kelsey completes 5 paintings. How many more paintings does she need to complete before she has completed 38 paintings?

Answers

In one month she completed 5 paintings, so in 6 month she completed 6 * 5 = 30 paintings.

38 - 30 = 8 - that's how many paintings she's still about to complete.

If she can do 5 paintings in one month, she'll do 8 paintings in 1 3/5 months. If we assume that month has 30 days, she'll probalby need one month and 18 days to do it (because 3/5 from 30 is 18).

Final answer:

Kelsey has painted 30 paintings over 6 months. She needs to paint 8 more to reach her goal of 38 paintings.

Explanation:

The subject of this question is mathematics and it sounds like a grade-appropriate question for middle school. To figure out how many more paintings Kelsey needs to complete to reach 38, we can use multiplication and subtraction.

 

First, we multiply the number of paintings Kelsey completes each month (5) by the number of months (6). This gives us a total of 30 paintings.

Then, we subtract this number from the total number of paintings Kelsey wants to complete (38). The result is the number of additional paintings Kelsey needs to complete.    

So, 38 - 30 = 8. Kelsey needs to complete 8 more paintings to reach her goal of 38 paintings.
