Answer:  There are 13 children.


Step-by-step explanation:

1. Let's call x the number of children in the classroom. We know that each child received 4 oranges, except 5 of them.

2. There were 32 oranges in total.

3. We can write this problem as an equation that represents the number of oranges distributed, as follows:

4(x-5)=32

4. Now we solve the equation to find the value of x:

x-5=\frac{32}{4}

x-5=8

x=13

5. There are 13 children in the classroom. 8 of them received oranges and the rest did not.

lisabon 2012 [21]

Answer:

After 16 rounds the champion of Ping-Pong player can be determined.

Step-by-step explanation:

This is an example of geometric progression,

First term = 65,536

\texttt{Common ratio = }\frac{1}{2}

Now we need to find which term is 1 in this GP.

N th term of GP is given by

             t_n=ar^{n-1}

Substituting

               1=65536\times \left ( \frac{1}{2}\right )^{n-1}\\\\\frac{1}{65536}=\left ( \frac{1}{2}\right )^{n-1}\\\\2^{n-1}=65536\\\\2^{n-1}=2^{16}\\\\n=17

Seventeenth term of this GP is 1.

That is after 16 rounds the champion of Ping-Pong player can be determined.

The price to ship a box varies directly as the weight of the box in pounds. A box that weighs 10 pounds costs $10.90 to ship.
nydimaria [60]
Well we can say 10.90/10 = the cost per pound to ship the item
we can infer this from the above text so
10.90/10 = 1.09.
So 1.09 * 37 = 40.33
$40.33
or 40 dollars and 33 cents to ship the second box with a weight of 37lb (pounds).

Simplify 2(x – 4) + 32: Simplify 9x + 4(x + 2) – 5:
Reika [66]

Answer:

Step-by-step explanation:

1)  

2(x – 4) + 32

Multiply it out.

2 * x - 2 * 4 + 32

2x - 8 + 32  

2x + 24

2)

9x + 4(x + 2) – 5

Multiply it out

9x + 4 * x + 4 * 2 - 5

9x + 4x + 8 - 5

13x + 3

PLEASE ANSWER! (BRAINLIEST)
gavmur [86]

First, find the distance AB by the formula:

AB=\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}.

If A(0,-7) and B(8,8), then

AB=\sqrt{(8-0)^2+(8-(-7))^2}=\sqrt{8^2+15^2}=\sqrt{64+225}=\sqrt{289}=17.

Dilating polygon ABCD by a scale factor of 2 with the center of dilation at the origin to create polygon A′B′C′D′, you increase the distance AB twice, A'B'=2AB. Thus, A'B'=2·17=34 units.

Answer: AB=17 units, A'B'=34 units.
