Sandy has 27 roses, 9 daisies, and 18 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?
Answer:
The greatest number of flowers that could be in a bouquet is 9 flowers
Step-by-step explanation:
We solve the above question using Greatest Common Factor method. We find the factors of 27, 9 and 18. The greatest factor common to the 3 number is our answer.
The factors of 9 are: 1, 3, 9
The factors of 18 are: 1, 2, 3, 6, 9, 18
The factors of 27 are: 1, 3, 9, 27
Then the greatest common factor is 9.
The greatest number of flowers that could be in a bouquet is 9 flowers
Why is the percent increase from 45 to 75 not equal to the percent decrease from 75 to 45? Select three options.
UThe amount of change drent for the percent increase and the percent decrease
UThe ratio of the percent increase is not the same as the percent decrease.
OThe ratio for the percent increase has a smaller denominator than the percent decrease.
U The ratio for the percent increase has a different numerator than the percent decrease.
O The original amount for the percent increase is different from the original amount for the percent decrease.
Answer:
work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease.

Find the total surface area of this prism where
the cross-section is an isosceles triangle.
13 cm
5 cm
10 cm
24 cm
Answer:
The total surface area of the prism is 620 cm²
Step-by-step explanation:
The total area of the prism = lateral area + 2 (area of the cross-section)
The lateral area = perimeter of the cross-section × height
∵ The cross-section of the prism is an isosceles triangle
∵ The sides of the triangle are 13 cm, 13 cm, 24 cm
∵ The perimeter of the triangle is the sum of its sides
∴ The perimeter = 13 + 13 + 24 = 50 cm
∴ The perimeter of the cross-section = 50 cm
∵ The height of the prism is 10 cm
→ Use the rule of the lateral area above to find it
∴ The lateral area of the prism = 50 × 10 = 500 cm²
∵ The area of the triangle = [tex]\frac{1}{2}[/tex] × base × height
∵ The base of the triangle = 24 cm
∵ The height of the triangle = 5 cm
∴ The area of the triangle = [tex]\frac{1}{2}[/tex] × 24 × 5 = 60 cm²
∴ The area of the cross-section = 60 cm²
→ Substitute the lateral area and the area of the cross-section in the rule
of the total surface area above
∵ The surface area = 500 + 2(60)
∴ The surface area = 500 + 120
∴ The surface area = 620 cm²
∴ The total surface area of the prism is 620 cm²

Juan wants to solve the equation below using the Distributive Property.
4(6 – x) = 12
What should Juan’s first step be?
A. Multiply 4 by x.
B. Subtract x from 6.
C. Distribute 4 to (6 – x).
D. Subtract 4 from both sides.
Answer:
C. Distribute 4 to (6 - x).
Step-by-step explanation:
Person above is right.
Juan’s first step should be C. Distribute 4 to (6 – x).
What is distributive property of multiplication over addition?Suppose a, b and c are three numbers. Then we have:
a(b + c) = a b + a c
(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)
We are given an equation as;
4(6 – x) = 12
Here Juan wants to solve the equation, using the Distributive Property.
thus, 4(6 – x) = 12
First step is to distribute 4.
4(6) – 4(x) = 12
Then solve;
24 - 4x = 12
x = 3
Hence, Juan’s first step should be C. Distribute 4 to (6 – x).

(5,6) and (−5,12) what is the rate of change??
Answer:
- 0.6
Step-by-step explanation:
Start point: (5,6)
End point: (-5,12)
rate of change = (12-6) / (-5-5) = 6/-10 = - 3/5 = - 0.6
Answer:
The rate of change is -0.6
Step-by-step explanation:
Given
[tex](x_1,y_1) = (5,6)[/tex]
[tex](x_2,y_2) = (-5,12)[/tex]
Required
Determine the rate of change
The rate of change means the slope (m) and it is calculated as thus:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{12-6}{-5-5}[/tex]
[tex]m = \frac{6}{-10}[/tex]
[tex]m = -\frac{6}{10}[/tex]
Simplify the fraction
[tex]m = -\frac{3}{5}[/tex]
[tex]m=-0.6[/tex]
The rate of change is -0.6

How would you solve equations with 3 sides or whatever this is
Answer: B. -4 < y < -1
Step-by-step explanation:
1. Subtract 2 from all three sides to isolate the variable in the center of the inequality
5 < 2 - 3y < 14
3 < -3y < 12
2. Divide each of the three sides by -3 to get y by itself, as each of the answers have y as independent.
3 < -3y < 12
-1, y, -4
3. Rearrange
-4 < y < -1 (b)

Step-by-step explanation:
22+15x=34-17x
So now, the 34 will join the 22 and the 15x will join the -17x
22-34=-17x-15x
-12=-2x

X = 5 and Y = 8
Step-by-step explanation:
4x + 3y = 44
3x + 3y = 39
- - -
__________
x = 44 - 39
x = 5........eq 1
Now putting the values in any equation
4 ( 5 ) + 3 y = 44
20 + 3 y = 44
[tex]4(5) + 3y = 44[/tex]
[tex]20 + 3y = 44[/tex]

Find the value of n.
Answer:
20cm
Step-by-step explanation:
Answer:
n = 15
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here b = n + 1 and h = n + 1 - 5 = n - 4 , then
[tex]\frac{1}{2}[/tex](n + 1)(n - 4) = 88 ( multiply both sides by 2 to clear the fraction )
(n + 1)(n - 4) = 176 ← expand the left side using FOIL
n² - 3n - 4 = 176 ( subtract 176 from both sides )
n² - 3n - 180 = 0 ← in standard form
(n - 15)(n + 12) = 0 ← in factored form
Equate each factor to zero and solve for n
n - 15 = 0 ⇒ n = 15
n + 12 = 0 ⇒ n = - 12
However, n > 0 , thus value of n = 15
