Find two consecutive even integers such that twice the smaller is 16 more than the larger.

qwelly [4]

Answer: smaller: 18 ; larger: 20

Step-by-step explanation:

Let n be the smaller integer. Then the larger integer is n+2. So:

2n=n+2+16

n=18

The smaller integer is 18; the larger one is 20.

Answer:

option D. 126 cm

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

Triangles PQR and XYZ are similar by AA Similarity Theorem

$\frac{XY}{PQ}=\frac{YZ}{QR}=\frac{XZ}{PR}$

Let

z ---> the scale factor

$z=\frac{XY}{PQ}$

substitute the given values

$z=\frac{30}{5}=6$

step 2

Find the perimeter of triangle XYZ

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

Let

z ----> the scale factor

p_1 ----> the perimeter of triangle XYZ

p_2 ---> the perimeter of triangle PQR

$z=\frac{p_1}{p_2}$

The perimeter of triangle PQR is

$p_2=5+10+6=21\ cm$

we have

$z=6\\p_2=21\ cm$

substitute

$6=\frac{p_1}{21}$

$p_1=6(21)=126\ cm$

therefore

The perimeter of triangle XYZ is 126 cm

A population of mold decays at a rate of 30 mold spores per day if the initial population of mold spores is 1560 spores how many

KonstantinChe [14]

Answer:

Step-by-step explanation:

In the first day the population will decrease to 1530, then 1500 the day 2, 1470 day 3, and so on ...

For decrease and get less than 1000 the mold population needs to be reduced in at least 560. The questions turns to be, how many days will it take to reduce the population in 560 spores?

If we divide 560 between 30 it will gives us the answer:

560/30 = 18.667

So, it is need to wait 19 days. In 18 days only 540 spores are reduced. In 19 days 570. We will say 19 days as we are looking (I guess) for an integer number.
