Answer:
-1.5
Step-by-step explanation:
D. X = -7
Step 1: Subtract 8 from both sides.
x + 8 - 8 = 1 - 8
Answer:
x = -7
Answer:
1) Numerical expression that represents the area Sabrina painted the first weekend:
2) Area that Sabrina painted the first weekend:
3) How much more of the total area she painted the first weekend than in the subsequent 3 weekends:
Explanation:
<u>1) Data:</u>
- a) Total area that Sabrina has to paint: 1,600 ft².
- b) Every weekend she paints half of the area that remains to be painted
- c) Number of weekends Sabrina paints: x
- c) Every wee
<u>2) Write a numerical expression that represents the area Sabrina painted the first weekend:</u>
- Half of 1,600ft² = (1/2) × 1,600 ft² =
<u>3) Find the area that Sabrina painted the first weekend.</u>
Compute:
- (1/2) × 1,600ft² = 1,600ft² / 2 = 800 ft²
<u>4) Find how much she painted after four weeks. </u>
- Second weekend: (1/2) 800ft² = 400ft²
- Third weekend: (1/2) 400ft² = 200ft²
- Fourth weekend: (1/2) 200ft² = 100ft²
Total area painted during those three weekends:
- 400ft² + 200ft² + 100ft² = 700ft²
<u>5) Find how much more of the total area she painted the first weekend than in the subsequent 3 weekends.</u>
This is the area she painted the first weekend, 800ft², less the area she painted the subsequent 3 weekends, 700ft²:
Answer:
Step-by-step explanation:
We are given that
Base side of square pyramid, a=3 m
Height of square pyramid, h=9m
We have to find the rate of change of the volume of the pyramid at that instant.
Volume of square pyramid, V=
Differentiate w.r.t t
Substitute the values
Hence, the rate of change of the volume of the pyramid at that instant=
Answer:
C. An Exponent
Step-by-step explanation:
It is C because the number being squared is called the base number. In this case the base number is x.
The exponent, the amount of times that the base number will be multiplying itself by is 2.
Therefore, in x^2, the 2 is the exponent.
