The answers to the questions are

The mathematical model is given as s = −16t2 + 1054
The height after 4.5 seconds is 730 feet

the time it would take to strike the ground is 8.11 seconds.

<h3>How to solve for the position of the object</h3>

The mathematical model of this problem would be written as

s = −16t2 + v0t + s0

s0 = 1054

then we would have

s = −16t2 + 1054

b. after 4.5 seconds the height is going to be

s = −16t2 + 1054

= −16(4.5)² + 1054

= -16 * 20.25 + 1054

= 730

C. the time that it takes to strike the ground

s = −16t² + 1054

= 16t² = 1054

t² = 1054/16

= 65.88

t = √65.88

t = 8.11

Hence the time it would take to strike the ground is 8.11 seconds.

Verna shipped three packages to chicago. If the packages weighed 12 1/2, 35 1/4, and 41 7/20 pounds, what was the total weight?

stiv31 [10]

Answer:

Step-by-step explanation:

1st package weighs $12\dfrac{1}{2}$ pounds;

2nd package weighs $35\dfrac{1}{4}$ pounds;

3rd package weighs $41\dfrac{7}{20}$ pounds;

First, add whole numbers:

$12+35+41=88$

Now add fractions:

$\dfrac{1}{2}+\dfrac{1}{4}+\dfrac{7}{20}=\dfrac{10}{20}+\dfrac{5}{20}+\dfrac{7}{20}=\dfrac{10+5+7}{20}=\dfrac{22}{20}=\dfrac{11}{10}=1\dfrac{1}{10}$

So, the total weight is

$88+1\dfrac{1}{10}=89\dfrac{1}{10}\ pounds$

write a decimal division problem that has an estimated quotation of 4. explain how to get the estimation

vodomira [7]

9514 1404 393

Answer:

15.8 ÷ 3.9

Step-by-step explanation:

To make up this problem, we can start with two numbers whose quotient we know is 4, such as 16 and 4. Then we can choose two numbers that round to these values, such as 15.8 and 3.9

The problem 15.8 ÷ 3.9 has an estimated quotient of 4. The estimate is found by rounding each value to the nearest integer and finding the quotient of those numbers: 16/4 = 4.

_____

<em>Additional comment</em>

The actual quotient is 4 2/39, about 4.05128.
