Answer:

Horizontal distance is 142.12 feet.

Step-by-step explanation:

We have,

Velocity of the ball is 38.50 ft/sec. The angle of projection of the ball is 35 degrees.

It is required to find the horizontal distance covered by it before it comes back to the ground on its first bounce. It means we need to find the horizontal range of the projectile. Range of a projectile is given by :

R=\dfrac{u^2\sin2\theta}{g}\\\\R=\dfrac{(38.5)^2\times \sin2(35)}{9.8}\\\\R=142.12\ ft

So, the horizontal distance covered by it before it comes back to the ground on its first bounce is 142.12 feet.

Gunnar’s car gets 22.4 miles per gallon, and his gas tank can hold 17.82 gallons of gas. PART B: Gunnar’s car is close to empty
dedylja [7]

Answer:

399.17 miles

Step-by-step explanation:

Gunnar's car gets 22.4 miles per gallon. His gas tank can hold 17.82 gallons of gas.

Gunnar's car travels with one gallon of gas = 22.4 miles

He can travel with 17.82 gallon of gas = 17.82 × 22.4

                                                             = 399.168 ≈ 399.17 miles

Gunnar can travel 399.17 miles if he uses all of the gas in the gas tank.

Tell whether the two quantities vary directly. Explain your reasoning. The cafeteria provides three meals per day.
Dafna11 [192]

Answer:

The cafeteria provides three meals per day.

<u>Reason 1</u>

Yes, they vary directly  

As number of days increases ,Total number of meals i.e

1st day ⇒ 3

2nd day⇒6

3 rd day⇒9

4th day⇒12

......................

.........................

increases.

Total number of Meals = k×Number of days

But there is another possibility also

<u>Reason 2</u>

1 st day ⇒ 3

2nd day ⇒3

3rd day⇒ 3

.....................

.....................

As you can see from the above expression On each day number of meals is  

constant.

So we can say that ,

On each Day=Constant amount of meal=3

So, there is no Proportionality between Days and Meal.

Find the missing angles.
raketka [301]

Step-by-step explanation:

x = 90- 55 = 35

y = 180- x

y= 180 - 35 = 145

z =180- (y +10)

z = 180 - (145 +10)

z = 180-155

z = 25
