SAT QUESTION!!!

Mathematics
2 answers:
kakasveta [241]3 years ago
8 0

Step-by-step explanation:

Let x be the number of pages that were skimmed through.

Time taken to skim through = 10 * (x/15) = 2/3 x min.

Time taken to read through = 15 * [(275-x)/10] = 1.5(275-x) min.

We have 2/3 x + 1.5(275-x) = 350.

Therefore 412.5 - 5/6 x = 350 and x = 75.

Find the lcd of the pair of expressions
STALIN [3.7K]

\frac{2}{7}  {x}^{10}  {y}^{4}  \: and \:  \frac{2}{14}  {x}^{8}  {y}^{7} \\ lcd = 14 {x}^{10}   {y}^{7}
Answer is
14 {x}^{10}  {y}^{7}

When it's powered numbers, remember to choose the one with the largest power. For example,
{x}^{10}
And
{x}^{8}
Choose 10, same goes to y, where you choose 7 not 4 since 7 is larger.

Hope this helps. - M

A number a decreased by 7 is 2.
umka21 [38]

Answer:

9

Step-by-step explanation:

Let's first convert this to numbers. When a number is decreased by a certain amount, that is the same as saying that something is subtracted from it. Therefore:

a-7=2

Add 7 to both sides:

a-7+7=2+7

a=9

Hope this helps!

What is the answer to m
tigry1 [53]

Answer:

Height of a cell tower is, 30 m

Step-by-step explanation:

Proportion states that the two fractions or ratios are equal.

As per the given statement:

Let height of a cell tower be h.

Height of a pole = 3m ,

Shadow of a pole = 4 m and

shadow of a cell tower = 36+4 = 40 m

By definition of proportion;

\frac{\text{Height of a cell tower}}{\text{Shadow of a cell tower}} = \frac{\text{Height of a pole}}{\text{Shadow of a pole}}

Substitute the given values we get;

\frac{h}{40}=\frac{3}{4}

by cross multiply we get;

4h = 120

Divide both sides by 4 we get;

h = 30 m

Therefore, the height of a cell tower is, 30 m
