Let x be the number of apples left after Jim and Kellie eat.

We have an equation: x apples+ 20 apples+ 5 apples= 100 apples.

Now let's solve the above equation:
x+20+5=100
⇒ x= 100-5-20
⇒ x= 75.

The number of apples left is 75 (apples)~

I need help on this question (^～^;)ゞ

Answer:

21) x = 0

23) x = 7

Step-by-step explanation:

In a parallelogram, the opposite sides are congruent. Using this fact, we can create equations for both problems.

21)

$2x + 18 = 18$

Subtract 18.

$2x = 0$

Divide by 2.

$x = 0$

23)

$2x - 3 = 11$

Add 3.

$2x = 14$

Divide by 2.

$x = 7$

A stuntman jumping off a 20-m-High building is modeled by the equation h=20-5t^2, where t is the same in seconds. A high-speed c

Alchen [17]

Answer: $1\leq t\leq \sqrt{2}$

Step-by-step explanation:

1. You know that the high-speed camera is ready to film him between 15 meters and 10 meters above the ground.

2. The problem gives you the following equation:

$h=20-5t^{2}$

3. Therefore, you must calculate the time when $h=15$ and when $h=10$ , as following:

$h=15\\15=20-5t^{2}\\5t^{2}=5\\t=\sqrt{1}\\t=1$

$h=10\\10=20-5t^{2}\\5t^{2}=10\\t=\sqrt{2}$

4. Therefore, the answer is:

$1\leq t\leq \sqrt{2}$

Find the value of cos E rounded to the nearest hundredth, if necessary. please help thanks

bonufazy [111]

Answer:

cos(E)=0.8

Step-by-step explanation:

cos(E)=adjacent/hypotenuse

Using a common pythagorean triple, we can find that side GE is 30 (18^2+24^2=30^2)

Then we just get cos(E)=24/30, which is 0.8
