Answer/Step-by-step explanation:
4(x - 2)= 100 and 2(x - 2) = 50.
We can determine that in both equation x equals 27. But, why is the second one half as much as the first problem? This is because the second problem is being multiplied with a number half as large as the first. Since 27 - 2 = 25 and 25 x 4 = 100 and 25 x 2 = 50 these problems hold up to their function.
If x = 27:
<u>4(x - 2) = 100</u>
27 - 2 = 25
25 x 4 = 100
<u>2(x - 2) = 50</u>
27 - 2 = 25
25 x 2 = 50
5 squared + 12 squared = 169 and the square root of 169 is 5. The length of AB is 5.
Answer:
28.3 square inches
Step-by-step explanation:
In the question, we are asked to calculate the portion of the area of the cake eaten by Ellie’s sister.
To calculate this, the first thing to do is to calculate the area of the cookie cake. Now, since it’s a round cake, then it must be circular in shape.
Hence we calculate the area.
mathematically the area of a circle can be calculated using the formula;
A = pi * r^2
here our r =6 inches
Substituting this, we have
A = 22/7 * 6 * 6 = approximately 113 sq. inches
we now move on to calculate the portion ate, which is a quarter
That would be 1/4 * 113 = 28.3 sq. inches was eaten

Answer:
Step-by-step explanation:
First, let's simplify the expression on the right:
Next, rewriting 1/x as x⁻¹, we can use the power rule to differentiate both sides with respect to x:
