21 * 7 = 147

9 1/3 = 28/3

147 * 28 /3 = 4116/3

Simplify :

4116/3 = 1372

Volume = 1372 cm³.

Hope this helped☺☺

The volume is the product of length, width, and height.
  V = LWH
  V = (21 cm)(7 cm)(9 1/3 cm)
  V = (21*7*28/3) cm³
  V = 1372 cm³

The volume is 1372 cm³.

How much money must be deposited now in an
Liono4ka [1.6K]

Answer:

\$487.48

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

A=P(1+\frac{r}{n})^{nt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

t=10\ years\\ A=\$1,000\\ r=7.25\%=7.25/100=0.0725\\n=4  

substitute in the formula above

1,000=P(1+\frac{0.0725}{4})^{4*10}  

1,000=P(\frac{4.0725}{4})^{40}

P=1,000/(\frac{4.0725}{4})^{40}

P=\$487.48

PLEASE HELP!!!<br> THIS IS DUE SOON
Hoochie [10]

Answer:

It's 65

Step-by-step explanation:

The reason is because the whole thing needs to be 180 right.

So one of the sides is 67

D would have to be 65 because of the angle and also it is less then F.

E is 48 because it is cut.

So the answer would be 65

I hope this helps!

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below
gavmur [86]

Answer:

Tobias did best on the aptitude test.

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

For Emilio

Emilio got a score of 76; this version has a mean of 70.6 and a standard deviation of 9.

z = (x-μ)/σ

z = 76 - 70.6/9

z = 0.6

For Alissa

Alissa got a score of 298.8; this version has a mean of 282 and a standard deviation of 24.

z = (x-μ)/σ

z = 298.8 - 282/24

z = 0.7

For Tobias

Tobias got a score of 8.04; this version has a mean of 7.2 and a standard deviation of 0.4.

z = (x-μ)/σ

z = 8.04 - 7.2/0.4

z = 2.1

Looking at the calculated z score above, we can see that Tobias did better on his aptitude test because he had a higher z score compared to Emilio and Alissa.
