solve 35% of 84 using the mental method
Answers
Answer:
29 approximately
Step-by-step explanation:
You want to estimate 35% of 84. 35% is roughly equivalent to 1/3, so multiply 84 by 1/3 (or, equivalently, divide 84 by 3), obtaining 28. Use a calculator to find 0.35(84): 29.4. This 28 is a fairly good estimate of 35% of 84 which is 29.4.

A ball is thrown into the air with an upward velocity of 44 ft/s. It’s height h in feet after t seconds is given by the function h=-16t^2 +44t+5. How long does it take the ball to reach its maximum height? What is the balls maximum height?

Answer:
1.375 seconds35.25 feetStep-by-step explanation:
A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).
Here, we have ...
h = -16t^2 +44t +5
t = -44/(2(-16)) = 11/8 = 1.375
It takes 1.375 seconds for the ball to reach its maximum height.
The height at that time is ...
h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25
The maximum height is 35.25 feet.

Mr. Armstrong went to Target to buy four pairs of dress socks. There was a 30% off sale
on the socks, and his total bill before tax was $14. What was the price of each pair of socks
before the sale?
Answers
Answer: $5
Step-by-step explanation:
We should note that since there was a 30% off sale, it means that he paid for 70% (100% - 30%) of the sales price.
Therefore, let the price of the socks be represented as x.
70% of x = 14
70/100 × x = 14
0.7 × x = 14
0.7x = 14
x = 14 / 0.7
x = 20
Therefore, the price of the socks was $20. Since there are 4 pairs, each pair will be:
= $20 / 4
= $5
