Answer:
400 girls.
480 boys.
Step-by-step explanation:
If the number of girls is x then the number of boys is 1.2x, so we have:
x + 1.2x = 880
2.2x = 880
x = 880/2.2
= 400.
Girls = 400, boys = 1.2*400 = 480.

You must show your work and present your answer for credit. Just an answer will result in no credit. If you are not sure what this means, take a quick look at the videos or recorded lesson. A. B. X - 3.5 = 9.1
Answer:
[tex]X = 12.6[/tex]
Step-by-step explanation:
Given
[tex]X - 3.5 = 9.1[/tex]
Required
Solve for X
Add 3.5 to both sides
[tex]X - 3.5 +3.5 = 9.1 + 3.5[/tex]
[tex]X = 9.1 + 3.5[/tex]
[tex]X = 12.6[/tex]
What is the area of the sector of the circle when the radius is 10 and the shaded part is 45 degrees
Answer:
We are solving for the area so; A=134.16
Step-by-step explanation:
Here is the formula for finding area of a sector:
A = [tex]\pi r^{2}[/tex] × θ° ÷ 360°
where theta is the angle of the sector you wish to find, and r is the radius of the circle.
Substitute the numbers in and you get:
[tex]\frac{25\pi }{2} unit ^{2}[/tex]

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given,
A group of college students spent $58.50 for dinner
The students want to leave a tip of 15%.
We need to find how much they has to leave as tip.
Firstly we have to convert 15% to decimal.
We have to divide 15 by 100
15/100
0.15
Now we have to multiply 0.15 with 58.50 to find the 15% of 58.50
0.15×58.50
8.775
9
Hence, $9 is the tip the students has to leave.

Answer:
y = 4x
Step-by-step explanation:
A parallel line will have the same slope. The given line is written in "slope-intercept form", so the slope is readily identified from the equation.
y = mx + b . . . . . line with slope m and y-intercept b
y = 4x -7 . . . . . . line with slope 4 and y-intercept -7
So, the parallel line will be something of the form ...
y = 4x + b
for any value of b. The simplest is to let b=0. If b=-7, then the lines are coincident, not parallel, so that value must be excluded. Any other value of y-intercept will give a parallel line.
y = 4x . . . . . parallel line

Answer:
x2 = -0.600000
x3 = -0.521600
Step-by-step explanation:
Given the formula;
xn+1 = (xn)³-5/10
x2 = (x1)³-5/10
Given x1 = -1
x2 = (-1)³-5/10
x2 = (-1-5)/10
x2 = -6/10
x2 = -0.600000
x3 = (x3)³-5/10
Given x3 = -0.6
x3 = (-0.6)³-5/10
x3 = (-0.216-5)/10
x3 = -5.216/10
x3 = -0.521600
