Step-by-step explanation:

first bring 87.5 to right

25t=12.5+87.5

25t=100.0

then bring 25 to right so it will divided

t=100.0/25

t=4

the population of a town is 1,03.500 if 56%of the population is male find the number of females in the town
bija089 [108]
The population you gave isn't formatted correctly so I'll solve the problem assuming you mean 103,500.

First we find the number of males from the percentage given:

0.56 * 103500 = 57960 males

Subtract the number of males from the total population to get the number of females:

103500 - 57960 = 45540 females

You could solve the problem by finding the percentage of females first. Since there are 56% males, that means there are 100-56 = 44% females.

0.44 * 103500 = 45540

The answer is 45540.

The average of a list of 4 numbers is 90.0. A new list of 4 numbers has the same first 3 numbers as the original list, but the f
Thepotemich [5.8K]

Answer:

the average of this new list of numbers is 94

Step-by-step explanation:

Hello!

To answer this question we will assign a letter to each number for the first list and the second list of numbers, remembering that the last number of the first list is 80 and the last number of the second list is 96

for the first list

\frac{a+b+c+80}{4} =90

for the new list

\frac{a+b+c+96}{4} =X

To solve this problem consider the following

1.X is the average value of the second list

2. We will assign a Y value to the sum of the numbers a, b, c.

a + b + c = Y to create two new equations

for the first list

\frac{y+80}{4} =90

solving  for Y

Y=(90)(4)-80=280

Y=280=a+b+c

for the second list

\frac{y+96}{4} =X\\

\frac{280+96}{4} =X\\x=94

the average of this new list of numbers is 94

Choose the equation below that represents the line that passes through the point (7, -2) and has a slope of -3
Ray Of Light [21]

Answer:

B

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 3 and (a, b) = (7, - 2 ), thus

y - (- 2) = - 3(x - 7) , that is

y + 2 = - 3(x - 7) → B

#5. What is the length of segment DC ?
DanielleElmas [232]

Answer:

6 units

Step-by-step explanation:
