1 answer:

3 0

The factors of 50a³ are 1, 2, 5, 10, 25, 50,
   and their products with a, a² and a³ .

The factors of 10a² are 1, 2, 5, 10,
    and their products with 'a' and a² .

Their common factors are 1, 2, 5, 10,
   and their products with 'a' and a².

Their greatest common factor is 10a² .

(Another way to spot it, easily, is to remember this helpful factoid:

   If the smaller number is a factor of the larger number,
   then the smaller number is their greatest common factor.

Using the greatest common factor, then . . .

   50a³ + 10a² =   10a²(5a + 1) .

Aiden borrows a book from a public library. He read a few pages on day one. On day two, he reads twice the number of pages than

Fofino [41]

Let the number of pages read on day 1 be = x

Then on day 2 he read twice the pages from day one, it is = 2x

On 3rd day he read 6 pages less than 1st day, it is = x-6

Total pages are = 458

The equation becomes: $x+2x+x-6=458$

$4x-6=458$

$4x=464$

$x=116$

So on the third day, Aiden read $x-6=116-6=110$ pages.

A model of a famous statue is 2 1/2 inches tall. The actual statue is 3 1/3 feet tall. What is the ratio of the height of the mo

Gekata [30.6K]

1. A model of a famous statue is $2\dfrac{1}{2}$ inches tall that is

$\dfrac{2\cdot 2+1}{2}=\dfrac{5}{2}$ in.

2. The actual statue is $3\dfrac{1}{3}$ feet tall that is

$\dfrac{3\cdot 3+1}{3}=\dfrac{10}{3}\ ft=\dfrac{10}{3}\cdot 12=40\ in.$

3. The ratio of the height of the model to the height of the actual statue in simplest form is

$\dfrac{\dfrac{5}{2}}{40}=\dfrac{5}{2}\cdot \dfrac{1}{40}=\dfrac{1}{16}.$

Answer: $\dfrac{1}{16}.$

sergejj [24]

740-707.60=32.40
707.60-675.20=32.40
675.20-642.80=32.40
so that means every month you are paying 32.40$ bill. to get how many months you can pay phonebills without depositing any more money devide the 740/32.40=22.83 but you can not pay bill for the 0.83 month so answer will be 22 months

Math Question:<br> Pls help I will do anything

kow [346]

Answer:

The probability of spinning red is $\frac{1}{3}$ , the probability of spinning a 1 is $\frac{1}{6}$ , the probability of spinning an odd number is $\frac{1}{2}$ , and the probability of spinning a 9 is 0.

Step-by-step explanation:

Since there are a total of 6 possible outcomes, you can use this in the following questions. There are 2 red tiles, so the probability of spinning red is $\frac{2}{6}$ or $\frac{1}{3}$ . Since there are only one 1 tile, the probability of spinning a 1 is $\frac{1}{6}$ . Since there are three odd numbers, the probability of spinning an odd number is $\frac{1}{2}$ . Since there are no 9 in the spinner, the probability of spinning a 9 is 0 or never.
