Answer:
B. 21 and 19/25
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
21.76=21.761
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100
21.761×100100=2176100
Find the Greatest Common Factor (GCF) of 2176 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 4,
2176÷4100÷4=54425
Simplify the improper fraction,
=211925
In conclusion,
21.76=211925
Answer:
<u>For the first answer (A)</u>
The area of the base is the area of the 8 by 4 rectangle, minus the missing 2 by 2 square in the top-right. This is 8*4-2*2=32-4=28 square centimeters.
<u>For the second answer (B)</u>
The volume of the prism is the base area multiplied by the height, or 28*10=280 cubic centimeters.
x- intercept (- 8, 0), y- intercept (0, 8)
Step-by-step explanation:
To find the y- intercept, let x = 0 in the
equation and solve for y
y = 0 +8 =8 (0,8 ) y -intercept
To find the x- intercept, let y = 0 in the
equation and solve for x
x + 8 = 0 ( subtract 8 from both sides )
x=- 8 (-8, 0) intercept.

Answer:
(x, y) = (-4, 4)
Step-by-step explanation:
You find the values of x and y by working the problem using any of the methods of solving simultaneous equations that you have been taught.
Here, you observe that the y-coefficients are the same in each equation. That means you can cancel the y-terms by subtracting one equation from the other.
(7x +6y) -(4x +6y) = (-4) -(8)
3x = -12 . . . . simplify
x = -4 . . . . . . divide by 3
Now, you can substitute this into either equation to find y.
4(-4) +6y = 8
6y = 24 . . . . . . . . add 16
y = 4 . . . . . . . . divide by 6
The solution to this system of equation is ...
