Solve the following proportion. 15/21=5/x A. 3 B. 105 C. 7 D. not given

Slav-nsk [51]

If you would like to solve the following proportion 15 / 21 = 5 / x, you can do this as follows:

15 / 21 = 5 / x /*x
15 / 21 * x = 5 /*21
15 * x = 5 * 21 /15
x = 5 * 21 / 15
x = 7

The correct result would be C. 7.

Tom and Jerry leave from the same place in opposite directions. Tom drives 38mph. Jerry drives 50mph. In how many hours are they

devlian [24]

Answer:

Both Tom and Jerry will apart 176 miles in 2 hours .

Step-by-step explanation:

Given as:

Tom and Jerry moves in opposite direction

The speed of Tom = 38 mph

The speed of Jerry = 50 mph

Let The distance cover by Tom = x mile

The distance cover by Tom = ( 176 - x ) miles

Time taken by both are same = T hour

$\textrm(Time) = \dfrac{\textrm(Distance)}{\textrm(Speed)}$

Or, Time taken by Tom

T = $\frac{x}{38}$ ... 1

∴ x = 38 T

And Time taken by Jerry

$\textrm(T) = \dfrac{\textrm(Distance)}{\textrm(Speed)}$

Or, T = $\frac{176 - x}{50}$

So , put the value of T from 1

$\frac{x}{38}$ = $\frac{176 - x}{50}$

Or, 50 × x = ( 176 - x ) × 38

So 50 x + 38 x = 6688

Or, 88 x = 6688

∴ x = $\frac{6688}{88}$ = 76 mile

So, From, eq 1

T = $\frac{x}{38}$

or, T = $\frac{76}{38}$ = 2 hours

Hence both Tom and Jerry will apart 176 miles in 2 hours . Answer

Y varies directly with x it has a constant rate of change of 6. When the value of y is 11, then the value of x could be?

makvit [3.9K]

Answer: $\frac{11}{6}$

Explanation:

y varies directly with x means: $\frac{y}{x} = k$ ; where k is the rate

$\frac{y}{x} = k$
$\frac{11}{x} = 6$
$(x)\frac{11}{x} = 6(x)$
11 = 6x
$\frac{11}{6} =\frac{6x}{6}$
$\frac{11}{6} = x$

Volume

CaHeK987 [17]

Answer:

3.75 feet.

Step-by-step explanation:

Given:

The volume of a right octagonal prism is 30 cubic feet.

The area of the octagonal base is 8 square feet.

Question asked:

What is the height of the prism ?

Solution:

As we know:

 $Volume\ of \ octagonal-prism=base\ area\times height$

$30=8\times height\\ \\ By\ dividing\ both\ sides \ by\ 8\\ \\ \frac{30}{8} =\frac{8}{8} \times height\\ \\ 3.75=height$

Therefore, height of the prism is 3.75 feet.
