A cube has volume of 7^3 cubic centimeters. What is its surface area
Answers
294
reason:
the edge length is 7
multiply 7x7 to get the area of each face of the cube, 49
multiply 49 by the number of faces, 6, to get 294
Answer:
294
Step-by-step explanation:
The volume of a cube is calculated by multiplying one
of its equal edge with itself three times which is shown as a^3
If the volume of the given cube is = 7^3 then the edge length is = 7
To find the surface area we we multiply the square of the edge by 6

Answers
Answer:
f(4) = -10
x = 0
Step-by-step explanation:
From the graph attached,
For x = 4,
Value of the function will be,
f(4) = y value at x = 4
f(4) = -10
Similarly, for y = g(x) = 2,
x value of the function will be,
x = 0
For which g(0) = 2
Therefore, for x = 0 value of the function will be 2.
g(0) = 2

a temperature recorded in Antarctica was -122 F. The temperature recorded in the desert was 133 F. how many degrees warmer is 133 F than 122 F
Answers
Answer:
255 F
Step-by-step explanation:
133 + 122 = 225.
So that is the answer.
133°F is 255 degrees warmer than -122°F.
To find out how many degrees warmer 133°F is than -122°F, we can subtract the two temperatures:
Temperature difference = 133°F - (-122°F)
Remember that subtracting a negative number is the same as adding its positive value, so the calculation becomes:
Temperature difference = 133°F + 122°F
Temperature difference = 255°F
So, 133°F is 255 degrees warmer than -122°F.

Find the width and height of a 54 inch TV with the aspect ratio of 4:3. Then , find the area of the screen. You must draw and label a picture to help show ur work.
Answers
Answer:
The area of the screen is 1399.68 in²
Step-by-step explanation:
The given parameters are;
The size of the TV = 54 inch
The aspect ratio of the TV screen = 4:3
The size of the TV is given as the length, of the diagonal, therefore, we have;
The aspect ratio = Length, L:Width, W = 4/3 = L/W
L² + W² = 54²..................(1)
L/W = 4/3.........................(2)
Therefore, 3×L = 4×W
L = 4×W/3
Substituting the value of L in equation (1), we have;
(4×W/3)² + W² = 54²
16/9×W² + W² = 54²
25/9×W² = 54²
W² = 54²×9/25 = 1049.76
W = 32.4 inches
The length, L = 4×W/3 = 4×32.4/3 = 216/5 inches = 43.2 inches
The area of the screen = 43.2 inches × 32.4 inches = 1399.68 in²
The area of the screen = 1399.68 in².
