During a week-long dry spell, the water level in a pond decreased by 4 in. Per day, except for two days when it decreased by hal

Helga [31]

Answer:

24 inches.

Step-by-step explanation:

Given:

During a week the water level in a pond decreased by 4 in. Per day,

For two days, it decreased by half that amount = $4\times\frac{1}{2}=2\ inches\ per\ day$

Question asked:

How much did the water level decrease in the pond in one week?

Solution:

As we know, there are 7 days in a week.

For 5 days,

Each day water level decreased by = 4 inches

In 5 days, water level decreased by = $4\times5=20\ inches$

For exceptional 2 days:

Each day water level decreased by = 2 inches

In 2 days, water level decreased by = $2\times2=4\ inches$

Water level decreased in whole week = 20 + 4 = 24 inches

Therefore, water level decreased 24 inches in the pond in one week.

Amanda has already run 14 miles on her own, and she expects to run 5 miles during each track practice. How many tracks would it

mina [271]

Answer:

It will take Amanda 3 track practices to run 29 miles.

15/3=5

14+5x=29

subtract 14 from both sides

5x=15

divide both sides by 3

x=3

Find the value of x in the isosceles triangle shown below

egoroff_w [7]

Answer:

x = 10

Step-by-step explanation:

if there 2 same triangle then they are right triangle

By using Pythagorean theorem for 1 of right triangle, we have

$\sqrt{74} ^{2}$ = $7^{2}$ + $(\frac{x}{2}) ^{2}$

74 = 49 + $\frac{x^{2}}{4}$

74 - 49 = $\frac{x^{2}}{4}$

25 = $\frac{x^{2}}{4}$

therefore, x = $\sqrt{25*4}$ = $\sqrt{100}$ = 10
