Answer:
15 dimes, 12 quarters
Step-by-step explanation:
d + q = 27
.10d + .25q = 4.5
solve by substituting '27-q' for 'd'
.10(27-q) + .25q = 4.5
2.7 - .1q + .25q = 4.5
.15q = 1.8
q = 1.8/.15
q = 12
d = 27-12 which is 15
Given the function f(x)=2(3x+7)−4(x−2), what would be the value of input, x, if f(x)=18?
Answer: x=-2
Step-by-step explanation:
Given
f(x)=2(3x+7)-4(x-2)
f(x)=18
Use substitution method
2(3x+7)-4(x-2)=18
Expand parenthesis
6x+14-4x+8=18
Combine like terms
2x+22=18
Subtract 22 on both sides
2x+22-22=18-22
2x=-4
Divide 2 on both sides
2x/2=-4/2
x=-2

A high school will only offer a pottery class next year if at least 15 students sign up. So far, 9
students have signed up for the pottery class.
Let x represent how many more students need to sign up. Which inequality describes the
problem?
9 + X > 15
9 + x 2 15
Solve the inequality. Then, complete the sentence to describe the solution.
At least
more students need to sign up.
9+x≥15 is the inequality describes the problem and 6 more students should be added to the pottery class.
What is Inequality?a relationship between two expressions or values that are not equal to each other is called 'inequality.
Given that a high school will only offer a pottery class next year if at least 15 students sign up.
9 students have signed up for the pottery class.
Let x represent how many more students need to sign up.
9+x≥15
9+x≥15 is the inequality describes the problem.
Subtract 9 from both sides
x=15-9
x=6
So 6 more students should be added to the pottery class.
Hence, 9+x≥15 is the inequality describes the problem and 6 more students should be added to the pottery class.

7. Giovanni made the design below for an art project. What is the area of the drawing? 13 in. 5 in. 4in.
Answer:
75 in^2
Step-by-step explanation:
Given data
From the figure
We can see a rectangle and a triangle
The area of the rectangle is
Area= L*W
Area= 13*5
Area= 65 in^2
Area of the triangle
Area= 1/2b*h
Area= 1/2*4*5
Area= 2*5
Area= 10 in^2
Hence the area of the composite figure is
Area= 65+10
Area= 75 in^2
Sean pays £10 for 24 chocolate bars. He sells all 24 chocolate bars for 50p each.
Work out Sean's percentage profit.
Answer:
the percentage profit is 20%
Step-by-step explanation:
Given that
Sean paid £10 for 24 chocolate bars
He sold all 24 chocolate bars for 50p each
we need to find out the percentage profit
Since he paid £10 and sale value is (24 × 0.50) i.e. £12
So, the percentage profit is
= (£12 - £10) ÷ (£10)
= 20%
Hence, the percentage profit is 20%

Which answer choice shows that the commutative property does not hold for matrix multiplication?
Given:
The matrix statements in the options.
To find:
The answer choice that show the commutative property does not hold for matrix multiplication.
Solution:
We known that matrix multiplication is not commutative. if A and B are two non-zero matrices, then
[tex]AB\neq BA[/tex]
Let us assume,
[tex]A=\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\text{ and }B=\begin{bmatrix}1&3\\8&5\end{bmatrix}[/tex]
According to the above property of the matrix, we get
[tex]\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}\begin{bmatrix}1&3\\8&5\end{bmatrix}\neq \begin{bmatrix}1&3\\8&5\end{bmatrix}\begin{bmatrix}-1&-8\\-3&-5\end{bmatrix}[/tex]
Therefore, the correct option is B.

Find the volume of a cone with a radius of 6 centimeters and a height of 15 centimeters. Round your answer to the nearest tenth.
Answer: 565.3 cubic cm
Step-by-step explanation:
V= 1/3Bh
V= 1/3π r^2h
= 1/3 π (6 cm) ^2 (15 cm)
= 1/3 π (36 cm squared) (15 cm)
= 180π cubic cm
about 565.2 cubic cm
π is about 3.14
The value of the volume of a cone with a radius of 6 centimeters and a height of 15 centimeters is,
⇒ 565.2 cubic cm
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
In cone,
Radius = 6 cm
Height = 15 cm
Now, We know that;
Volume of cone is,
V = 1/3π r²h
Substitute all the values we get;
V = 1/3 π (6 cm)² (15 cm)
V = 1/3 π (36) (15)
V = 180π
V = 565.2 cubic cm
Thus, The value of the volume of a cone with a radius of 6 centimeters and a height of 15 centimeters is,
⇒ 565.2 cubic cm
