Clark is at a small arcade with some friends. Skeeball costs a quarter per game and air hockey costs 3 quarters per game. Clark
r-ruslan [8.4K]

Answer:

10 \geq s*0.25 + a*0.75

Step-by-step explanation:

Assign variable for each game

s = number of Skeeball games

a = number of Air hockey games

Then write out what you know...

1. Total cost of Skeeball = s*0.25

2. Total cost of Air hockey = a*(3*0.25) -> a*0.75

So the inequality would be...

10 \geq s*0.25 + a*0.75

A lawn in the shape of a trapezoid has an area of 1,833 square meters. The length of the other base is 42 meters. What is the he
Klio2033 [76]
The area of a trapezoid can be found with this formula:

A=\frac{1}2(b_1+b_2)h

Where b1 and b2 are the bases and h is the height.

If we plug in what we know we can solve for the height.
We know that b1 = 52, b2 = 42, and A = 1833. Let's solve.

1833=\frac{1}2(52+42)h\\1833=\frac{1}2\times94h\\1833=47h\\\boxed{h=39\ m}

Katena32 [7]

Answer:

14

Step-by-step explanation:

So, if x is length, then x*x*8 is 1568. To solve, you do 1568/8, which gives you 196. The square root of 196 is 14, and 14*14*8 is 1568.

What kind of solution is this 13x-5=-5+13x
Gre4nikov [31]

Answer:

B.

Step-by-step explanation:

Try solving:

13x - 5 = - 5 + 13x

13x - 13x = -5 + 5

0 = 0.

Therefore it is an identity.

We could make x any real value and the identity would hold.
