Answer:

765

Step-by-step explanation:

Craig picks 4 times 459 apples, or 1836 apples. The total number Lori and Craig picked is ...

total apples = 459 +1836 = 2295

Each of the three equal groups will have 1/3 this number of apples, so will have ...

1/3 × 2295 = 765 . . . apples

There are 765 apples in each group.

Since the expression (x-4)^2+(y+1)^2 evaluated at (3,6) is

stiks02 [169]

$\bf (x-4)^2+(y+1)^2\qquad (3,6)~~ \begin{cases} x = 3\\ y = 6 \end{cases}\implies (3-4)^2+(6+1)^2 \\\\\\ (-1)^2+7^2\implies 1+49\implies 50$

A textbook store sold a combined total of 460 physics and math textbooks in a week. The number of math textbooks sold was 62 les

sergij07 [2.7K]

Number of physics textbooks sold was 261 & number of maths textbooks sold was 199.

Let, the number of physics textbooks sold = x

According to the question,

The number of math textbooks sold was 62 less than the number of physics textbooks sold.

So, Number of maths textbooks sold = x-62

The textbook store sold a combined total of 460 physics and math textbooks in a week.

So, the equation becomes,

(x-62)+x = 460

⇒ x-62+x = 460

⇒ 2x-62 = 460

⇒ 2x = 460+62

⇒ 2x = 522

⇒ x = 522/2

⇒ x = 261

So, 261 physics textbooks were sold

(261-62) = 199 maths textbooks were sold.

90% of runners who started a marathon completed it. Of those, 30% are men. If 270 men completed the marathon, then how many tota

il63 [147K]

Given- 90% of runner completed the marathon.

out of which 30% are man.

To proof - let the total number of runner be y.

the men completed the marathon be 30% of the 90%.

thus we have

30% of 90% of y = 270

$\frac{30}{100}$ × $\frac{90}{100}$ ×y = 270

now solving the above equation

we get

$\\y=\frac{270\times 100\times 100}{90\times 30}$

Thus solving the equation

y = 1000

Thus the total runners of men who completed marathon be 1000.

Hence proved
