5. Debbie should've rounded the 2008 to 4,600 because 4,637 is less than 4,650. If it was over 4,650 it would've been rounded to 4,700. With the knowledge of the over 4,650 rule, we automatically know that in 2012 she was correct when she said 4,700.

Debbie is correct because you can not a percentage of a person therefore you have to round it, and if there was 5,000 female athletes in 2008 and 4,700. If you take 5,000 and subtract 4,700; the answer is 300.

Evaluate 19C1 PLEASE HELP

LiRa [457]

Answer:

${19}C_1=19$

Step-by-step explanation:

We need to find the value of ${19}C_1$ .

C stands for combination.

The formula of combination is as follows :

$nC_r=\dfrac{n!}{r!(n-r)!}$

Here,

n = 19 and r = 1

So,

$nC_r=\dfrac{19!}{1!(19-1)!}\\\\nC_r=\dfrac{19!}{1!\times 18!}\\\\nC_r=\dfrac{19\times 18!}{1!\times 18!}\\\\nC_r=19$

So, the value of ${19}C_1$ is 19.

Stolb23 [73]

Answer: $4.5\ ft^3$

Step-by-step explanation:

Given

Measurement of box $1\frac{1}{2}\times 1\frac{1}{2}\times 2$

suppose Length $L=1\frac{1}{2}=\frac{3}{2}\ ft$

Breadth $B=1\frac{1}{2}=\frac{3}{2}\ ft$

height $H=2\ ft$

Volume of Cuboid $=L\times B\times H$

Volume of Packaging box $V=\frac{3}{2}\times \frac{3}{2}\times 2$

$V=\frac{9}{2}\ ft^3$

Find the surface area of the rectangular prism.<br> 2 cm <br> 6 cm<br> 3 cm <br> 3 cm

Nookie1986 [14]

Answer:

72. If the second 3cm has some relevance, leave a note and I'll come back and modify my answer.

Step-by-step explanation:

Givens

L = 6 cm

W = 3 cm

H = 2 cm

I don't know what the extra 3 cm is for.

Formula

SA = 2*L*W + 2*L*H + 2*H*W

SA = 2*6*3 + 2*6*2 + 2*2*3

SA = 36 + 24 + 12

SA = 72

A mathematics Teacher brought 40 expensive calculator at 16400 each and a number of cheaper calculator costing tshs 5900 each. S

Novay_Z [31]

Answer:

20

Step-by-step explanation:

First, let's find how much she spent on the expensive calculators

40 times $16400= $656,000

Now, lets find how much money she had for the cheap calculators.

$774,000- $656,000=$118000

Now that we have her budget (money remaining) for the cheaper calculators, lets divide that by the price for each individual calculator.

$118000/$5900=20
