9(400 + 70 + 5). Distribute the nine to all the numbers in parentheses. 3600 + 630 + 45 = 4,275. 9 * 475 =4,275

Answer:

9\times 475 = 4275

Step-by-step explanation:

Distributive property of multiplication over addition:

a\times (b+c) = (a\times b) + (a\times c)

Now, we have to evaluate:

9\times 475

First we expand 475.

475 = 400 + 70 + 5

Now, we need to multiply this by 9.

9\times (400 + 70 + 5)\\= (9\times 400) + (9\times 70) + (9\times 5) \\= 3600 + 630 + 45\\=4275

Hence,

9\times 475 = 4275

red paint is 1 and blue paint is 3 how much red is there for each blue? Im low on points so u sadly only get 10
Lesechka [4]

Answer:

1 quart blue + 1 1/2 quart red

Given:

Ratio of blue paint : red paint = 1/3 : 1/2

simplifying this ratio into whole numbers by multiplying both sides by 2 and 3, we get:

(1/3) x (3x2) : (1/2) x (3x2)

2 : 3

From this we can determine the fractions of red and blue paint used in any total purple mix

fraction of blue paint = 2/(2+3) = 2/5 of purple mix

fraction of red paint = 3/(2+3) = 3/5 of purple mix

we are given that we want to make 2 1/2  (= 5/2) quarts of purple paint

hence

amount of blue paint

= fraction of blue paint in purple mix x total amount of purple paint

= (2/5) x (5/2) = 1 quart

amount of red paint

= fraction of redpaint in purple mix x total amount of purple paint

= (3 /5) x (5/2) = 3/2 quart = 1 1/2 quart

Blocks numbered 0-9 are placed in a box and a black is randomly picked the probability of picking an odd prime number is
Andrews [41]

Answer:

Step-by-step explanation:

B_n = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9\\B_p = 2, 3, 5, 7\\B_{o_p} = 3, 5, 7\\

There are 3 odd primes, namely : 3, 5, 7

The total amount of blocks is 9

The odds of picking and odd prime is \frac{3}{9} \cdot 100\% = 33,(3)\%
