Answer:

$V=416\ mm^3$

Step-by-step explanation:

we know that

The volume of a rectangular prism is given by the formula

$V=LWH$

we have

$L=10.4\ mm\\W=5\ mm\\H=8\ mm$

substitute in the formula

$V=(10.4)(5)(8)=416\ mm^3$

Please help, I have redone this problem a million times and i cant get it right. Time sensitive!!

Advocard [28]

Answer:

Step-by-step explanation:

This should be easy one unless you're making silly mistake like forgetting to take reciprocal of $\frac{3}{2x}$

lets do it:

$\frac{x+2}{x-1}$ ÷ $\frac{3}{2x}$ first: we take the reciprocal of 3/2x now its

$\frac{x+2}{x-1}$ * $\frac{2x}{3}$ now just multiply top and bottom by using distributive method

$\frac{2x^2 +4x}{3x-3}$ this is your answer.

What is 25 5/8 - 10 1/8

Delvig [45]

Subtract 25 and 10 which gives you 15
subtract 5/8 and 1/8 since they have common denominators.
You get 15 1/2 when you simplify 15 4/8 in which 4/8 is the same thing as 1/2.

Together, two boys had 43 cents. The first boy spent 5 cents and the second boy spent 13 cents. The first boy’s remaining money

o-na [289]

Hello kiddio lets figure this out!

Let x = first

y = second 

Then 

x - 5 = remainder of first 

y - 13 = remainder of second 

x - 5 = 2/3(y - 13) 

3x - 15 = 2y - 26 

3x - 2y = - 11................(1) 

x + y = 43....................(2) 

From (2) y = 43 - x..........(3) 

Put (3) in (1) 

3x - 2(43 - x) = - 11 

3x - 86 + 2x = - 11 

5x = 75 

x = 15 cents 

y = 43 - 15 

= 28 cents

A dinner cost $22 and a sales tax of $1.87 was added to the bill. How much would the sales tax be on a $66 dinner? What is the t

alexdok [17]

Answer:

The correct answer is the sales tax charged is $5.61 for $66 dinner at 8.5% tax rate.

Step-by-step explanation:

Cost of the dinner is $22. Tax levied on it is $1.87

Let x% is the rate of tax in the city.

Therefore, x% of 22 = 1.87

⇒ x = 1.87 × $\frac{100}{22}$ = 8.5

Therefore 8.5% is the tax rate in the city on foods.

Now another dinner costs $66.

Tax levied on it at the same percentage is given by 8.5% of 66 = $5.61.

Thus $5.61 as sales tax would be charged for a $66 dinner.
