the Hawk’s refrigerator compares to the Lopez’s refrigerator?

A.
The volume of the Hawk's refrigerator is 16 cubic inches greater than the volume of the Lopez's refrigerator.

B.
The volume of the Hawk's refrigerator is 16 times less than the volume of the Lopez's refrigerator.

C.
The volume of the Hawk's refrigerator is 16 times greater than the volume of the Lopez's refrigerator.

D.
The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator.

Answers

The correct statement that describes how the volume of the Hawk's refrigerator compares to the Lopez's refrigerator is: Option D.

D. The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator.

From the given information, we get,

The volume of the Hawk's refrigerator is given as 30 × 68 × 28.5 cubic inches.

The volume of the Lopez's refrigerator is given as (30 × 68 × 28.5) + 16 cubic inches.

We can see that the volume of the Lopez's refrigerator is obtained by adding 16 cubic inches to the volume of the Hawk's refrigerator.

Since 16 cubic inches are being added to the Hawk's refrigerator to get the Lopez's refrigerator, the volume of the Hawk's refrigerator must be 16 cubic inches less than the volume of the Lopez's refrigerator.

So, option D, "The volume of the Hawk's refrigerator is 16 cubic inches less than the volume of the Lopez's refrigerator," is the correct statement.

Answer:D

Step-by-step explanation:

What is the area of a square whose perimeter is 12?

Answers

We know that a square has an equal height and width. So if all 4 sides, which are equal in length, add up to 12, then we can find the length of one side by dividing 12 by 4:
12/4= 3

If the length of one side is 3, we can multiply the height (3) by the width (3) to find the area.
3*3= 9

Answer: the area of the square is 9.
P=4L
12=4L
3=L

A=L^2
A=3^2
A=9

Which term of the AP:3,15,27, 39,.....will be 132 more than its 54th term​

Answers

Answer:

n=65th term

Step-by-step explanation:

AP:3,15,27,39......

From the AP

a=3

a+d=15

a+2d=27

3+d=15 (1)

3+2d=27 (2)

Subtract (1) from (2)

We have,

2d-d=27-15

d=12

54th term=a+(n-1)d

=3+(54-1)12

=3+(53)12

=3+636

=639

The term is 132 more than the 54th term

132+54th term

=132+639

=771

Find the term

771=a+(n-1)d

771=3+(n-1)12

771-3=12n-12

768=12n-12

768+12=12n

780=12n

n=780/12

=65

n=12

The term which is 132 more than the 54th term is the 65th term

Which of the following equations is equivalent to y=2^x?y = log2x
x = log2y
y = logx2

Answers

Hello,

y=2^(x)

Answer B

Answer:

B, second part is X=20

Step-by-step explanation:

1 fourth B minus 10 equals 7

Answers

(1)/(4)b - 10 = 7
Take 10 to the other side.

(1)/(4)b = 17

Multiply by 4 to isolate b
(1)/(4)b × 4 = 17 × 4

4 and 4 cancels out
 
b = 68

Which of the following is a polynomial with roots 3, 5i, and −5i?f(x) = x3 − 3x2 + 25x − 75
f(x) = x3 − 3x2 + 15x − 25
f(x) = x3 − 15x2 + 25x − 75
f(x) = x3 − 3x2 + 15x − 75

Answers

x_(1)=3 \n \n x_(2)=5i \n \n x_(2)=-5i \n \n f(x)=(x-x_(1))(x-x_(2))(x-x_(3))=(x-3)(x-5i)(x+5i)= \n \n =(x-3)(x^(2)+25)=x^(3)+25x-3x^(2)-75=x^(3)-3x^(2)+25x-75
