Answer: 35 minutes
Step-by-step explanation:
For us to solve the question, we have to calculate the amount of gallons of water that is drained every minute. This will be:
= (1320 - 1040) / (9 - 2)
= 280/7
= 40 gallons per minute
Since we are told that 1,320 gallons of water remain in the pool after 2 minutes. This means that the total water in the pool at the beginning was:
= 1320 gallons + (40 × 2)
= 1320 gallons + 80 gallons
= 1400 gallons
The time taken for the pool to be completely drained will be:
= Total water in pool / Gallons drained per minute
= 1400 / 40
= 35 minutes
find the highest commen factor of 30 and 18
Answer:
6
Step-by-step explanation:
Use prime factorization;
30 = 2 * 3* 5
18 = 2 * 3 * 3
Both of these numbers have ( 2 * 3 ) in common, ( 2 * 3 = 6 ), hence their highest common factor (greatest common factor) is 6.
Answer: the common factor is 6
Step-by-step explanation:
the factor of 30=1x2x3x5
the factor of 18=1x2x3x3
the numbers that are common for both numbers are1, 2 and 3

The number expression (-5)⁵/(-5)⁻⁶ can be written as -5¹¹ after using the property of the integer exponent.
What is an integer exponent?In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.
We have:
A number expression:
= (-5)⁵/(-5)⁻⁶
As we know from the property of the integer exponent:
[tex]\rm = \dfrac{y^a}{y^b} = y{a-b}[/tex]
y is the base and a, b are the exponent.
As the same base can be written as the sum of the power
In the given number expression there is the same base as -5
Exponent can be subtracted, after subtracting the powers:
= (-5)⁵⁻⁽⁻⁶⁾
= (-5)⁵⁺⁶
= -5¹¹
Thus, the number expression (-5)⁵/(-5)⁻⁶ can be written as -5¹¹ after using the property of the integer exponent.

The measure of angle EDF from the given figure is 23°.
From the given figure, ∠EGF=23°.
What is and angles in the same segment theorem?The angles at the circumference subtended by the same arc are equal. More simply, angles in the same segment are equal.
By using angles in the same segment theorem, we get
∠EGF = ∠EDF = 23°
Therefore, the measure of angle EDF from the given figure is 23°.

Chaleah deposited $700 in a new account that earns 5 simple interest. After 4 years, how much interest will she have earned? How much total money will Chaleah have after 4 years
Answer:
FV= $875
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $700
Simple interest (i)= 5% = 0.05
Number of periods (n)= 4 years
To calculate the future value (FV), we need to use the following formula:
FV= PV*i*n + PV
FV= 700*0.05*5 + 700
FV= $875

the fifth term of an arithmetic progression is 40 and the seventh term is 28 more than the 3rd term. Find the first and 10th term.
Answer:
Step-by-step explanation:
t5 = a + (5-1)d
t5 = a + 4d
40 = a + 4d
t3 = a + 2*d
t7 = a + 2d + 28 = a + 6d
Start with the seventh term which has 2 equal answers
a + 2d + 28 = a + 6d Subtract a from both sides
2d + 28 = 6d Subtract 2d from both sides
28 = 4d Divide by 4
28/4 = d
d = 7
==================
t5 = a + 4d = 40
a + 4*7 = 40
a = 40 - 28
a = 12
===================
First term is 12
10th term is
t10 = 12 + (10 - 1)*7
t10 = 12 + 9*7
t10 = 75
