Can someone please explain the steps to solve these questions.
Amiraneli [1.4K]
Alright! So to solve these questions, you need to find out the difference. You can use ratios to solve this. For example, question #25:

A class had 30 pupils at the beginning of this school term, but now has 5 more pupils. What is the percent of increase?

The question is basically asking how much 5 is in ratio to 30. So just divide 5 (the given amount) by 30 (the total amount). The answer is 0.16, or 16%

Helllllppp please asap
BartSMP [9]

Answer:

1). a = 9.42 m

2). b = 6.37 m

3). c = 4.48 m

Step-by-step explanation:

In the figure attached,

By applying tangent rule in triangle ADE,

tan47 = \frac{h}{c}

c = \frac{h}{\text{tan}47}

c = \frac{4.8}{\text{tan}47}

c = 4.476

c ≈ 4.48 m

Now we apply the same rule in triangle ACE,

tan37° = \frac{h}{b}

b = \frac{h}{\text{tan}37}

b = \frac{4.8}{1.0724}

b = 6.37 m

Now apply the tangent in triangle ABE,

tan27° = \frac{h}{a}

a = \frac{h}{\text{tan}27}

a = \frac{4.8}{0.5095}

a = 9.42 m

2. You throw a softball straight up into the air at a velocity of 30 feet per second. You release the softball at a height of 5.
nadya68 [22]

Answer:

-16t^2+30t+5.8

Step-by-step explanation:

We are given that

Initial velocity=30 ft/s

Initial position=s_0=5.8 ft

We have to write a mathematical model for height of the softball by using the position equation

The position equation on Earth's surface is given by

h(t)=-16t^2+v_0t+s_0

Where v_0= Initial velocity

s_0=Initial position

Substitute the values in the equation then, we get

h(t)=-16t^2+30t+5.8

Hence, the mathematical model for height of the softball is given by

-16t^2+30t+5.8
