Its D, just read the graph buddy
Answer:
3x-20=-6.6 degrees, 7x+10=1.4 degrees
Step-by-step explanation:
You solve each equate separately. So take the equation (3x-20) and solve for x first in that one. so you divide 3 by -20 to get -6.66 degrees for your first angle. Then you solve the other equation. (7x+10) divide 7 by 10 to get the angle measurement. Which would be 1.4 degrees.
The goal in simplifying numbers
is to reduce it that can be best seen in the eye. In here, you are given 5a x 2c x
3d. Note that 5, 2 and 3 are coefficients and a, c and d, are variables. Multiply first
the coefficients 5, 2 and 3 and you get 30. Always remember that in multiplying
numbers, especially variables, the base of the exponent must be equal. However,
you have variables of a, c and, d. You cannot multiply or add them because they
are different. So the answer is 30acd.
Answer:
4 = 2*1+1
Step-by-step explanation:
Percentage change is 100% increase.
Step-by-step explanation:
- Step 1: Find volume of cylinder A using equation, V(A) = πr²h, where r = 7 in and h = 5 in
⇒ V(A) = π × 7 × 7 × 5 = 245π
and V(B) = 490π
- Step 2: Calculate percentage change from V(A) to V(B)
⇒ % change = [V(B) - V(A)/V(A)] × 100 = (490π - 245π/245π) × 100
= 245π/245π × 100 = 100% increase
