It takes 85 pails of water to fill up a tank. If the capacity of each pail is 2.65 gallons , what ai the capacity of the tank?

Taya2010 [7]

If u multiply the amount of gallons the pail holds by the amount of pails the tank can hold you would get 225.25 gallons.

Choose Yes or No to tell whether the expressions are equivalent.

Savatey [412]

Answer:

(4^3)3 and 4^3 • 4^3 = 192 and 4096 = No

(3^4)^4 and 3^8 • 3^8 = 43046721 and 43046721 = Yes

6^4 • 3^4 and 18^8 = 104976 and 11019960576 = No

4^3 • 5^3 and 2^0 = 8000 and 1 = No

Can someone plsss help i dont understand it

The Line PQ is cut half equally by point T. MEANING PT=TQ!!! So first, write out the equation.
PT = TQ
20?5x+3=7x-9
21?4x-6=3x+4
22?7x-24=6x-2
The question asks you to find the value of PT, but you’ll have to find the value of x first.
x=6
x=10
x=22
And then just just plug in x in just the PT equation.
5(6)+3= 33
4(10)-6= 34
7(22)-24= 130
and there you have it
20?=33
21?=34
22?=130

In the school chorus 4 24th of the students are fourth graders I'n the simplest form what fraction of the students in the school

Kamila [148]

Answer:

1/6

Step-by-step explanation:

Given:

Fraction of students that are in fourth grade = $\frac{4}{24}$

In order to reduce this fraction in to simplest form, we need to find the highest common factor for both the numerator and denominator and divide each of the numerator and denominator by the highest common factor (HCF)

The numerator is 4 and the denominator is 24.

Factors of 4 = 1, 2, <u>4</u>

Factors of 24 = 1, 2, 3, <u>4</u>, 6, 8, 12, 24

As seen from the above, the highest common factor for 4 and 24 is 4.

So, we divide both numerator and denominator by the highest common factor which is 4. This gives,

$\dfrac{4}{24}=\dfrac{4\div 4}{24\div 4}\\\\\\\dfrac{4}{24}=\dfrac{1}{6}$

Therefore, the fraction of students that are in fourth grade in simplest form is $\frac{1}{6}$ .
