The question is incomplete:

Find the number of boxes needed, x, for 42 granola bars. ​

The table with the information is attached.

Answer:

The number of boxes needed for 42 granola bars is 7.

Step-by-step explanation:

Since the table shows that for 12 granola bars 2 boxes are needed, you can use a rule of three with this information to find the number of boxes needed for 42 granola bars:

12 granola bars  → 2 boxes

42 granola bars →      x

x=(42*2)/12

x=84/12

x=7

According to this, the answer is that the number of boxes needed for 42 granola bars is 7.

What is the value of the expression 8p4
Nady [450]

ANSWER

8P_4 = 1680

EXPLANATION

We use the formula

nP_r =  \frac{n!}{(n - r)!}

For

8P_4

and n=8, r=4.

8P_4=  \frac{8!}{(8- 4)!}

This simplifies to

8P_4=  \frac{8!}{4!}

We expand the numerator using factorial notation,

8P_4=  \frac{8 \times 7 \times 6 \times 5  \times 4!}{4!}

The common factors cancel out.

8P_4=  8 \times 7 \times 6 \times 5

8P_4= 1680

Jake went on a riverboat tour. After returning from the tour, he was curious to know the speed at which the boat was going. Duri
atroni [7]
I'm sorry I'm too lazy to read all of that. However, I did get the main point. The river was going at 3 mph. Since he wanted to travel 10 miles upstream and downstream, you would have to subtract 20 by 3. This would mean he was going at a speed of 17 mph.

Kari is flying a kite. She releases 50 feet of string. What is the approximate difference in the height of the kite when the str
MakcuM [25]

Answer:

Step-by-step explanation:

The string of a kite forms a right angle triangle with the ground. The length of the string represents the hypotenuse of the right angle triangle. The height of the kite represents the opposite side of the right angle triangle.

To determine the height of the kite, we would apply the sine trigonometric ratio which is expressed as

Sin θ = opposite side/hypotenuse.

1) if the kite makes an angle of 25° with the ground, then the height, h would be

Sin 25 = h/50

h = 50Sin25 = 50 × 0.4226

h = 21.1 feet

2) if the kite makes an angle of 45° with the ground, then the height, h would be

Sin 45 = h/50

h = 50Sin45 = 50 × 0.7071

h = 35.4 feet

The approximate difference in the height of the kite is

35.4 - 21.1 = 14.3 feet
