Answer:

12.

Step-by-step explanation:

Each student needs to use the 1/8 spoon three times to get 3/8, you can get this result multiplying 3\frac{1}{8}.

So, there's four students, do the multiplication: 3 times 4 equals 12.

A right rectangular prism has length 3 and one third yd​, width 2 and one third yd​, and height 1 and one third yd. You use cube
Levart [38]

Answer:

Volume of the rectangular prism = 280 cubes

Volume of the rectangular prism = (280/27) yd³

Step-by-step explanation:

length 3 and one third yd​ = 3 + (1/3) yd = (10/3) yd

width 2 and one third yd​ = 2 + (1/3) yd = (7/3) yd

height 1 and one third yd = 1 + (1/3) yd = (4/3) yd

Cubes of edge length (1/3) yd are used to fill the rectangular prism.

The length would contain (10/3) ÷ (1/3) = 10

The width would contain (7/3) ÷ (1/3) = 7

The height would contain (4/3) ÷ (1/3) = 4

Volume of the rectangular prism = 10×7×4 = 280 cubes

Or

Volume of rectangular prism = (10/3)(7/3)(4/3) = (280/27) yd³

17.5 how to make this into a fraction
BARSIC [14]
Take the .5 of the 17.5 and convert it to a fractin.
we know .5 is equal to 50% or 1/2 

now we have a mixed number  17 \frac{1}{2}

in order to convert it into an improper fraction you need to multiply the whole number by the denominator and then add the numerator all while keeping the denominator constant. 

W \frac{N}{D} =  \frac{(W*D)+N}{D}

so 17 \frac{1}{2}= \frac{(17*2)+1}{2}= \frac{35}{2}

Andre and Elena knew that after 28 days they would have 2²⁸ coins, but they wanted to find out how many coins that actually is.
vlada-n [284]

Answer:

I agree with none of them

Step-by-step explanation:

Given

Expression= 2^{28}

Andre: 2 * 28 = 56

Elena: 28 * 28 = 756

Required

Who is correct?

Expression= 2^{28}

When we apply law of indices to the above, it gives 2 multiplies by itself in 28 places

i.e.

Expression= 2^{28}

Expression= 2*2*2*..........*2 ---- in 28 places

Andre's interpretation of the expression is incorrect as:

2^{28} \neq 56

Also, Elena's expression is incorrect.

This is so, because

2^28 \neq 28*28

<em>Hence, both of them are incorrect and I agree with none of them</em>
