number of boys:number of girls= 11:9
There are 124 more boys than girls.
Work out the total number of students at the school
Answer:
Total students = 1240
Step-by-step explanation:
Boys : girls = 11 : 9
Number of boys = 11x
Number of girls = 9x
11x - 9x = 124
2x = 124
x = 124/2
x = 62
Number of boys = 11x = 11 *62 = 682
Number of girls = 9x = 9*62 = 558
Total students = 682 + 558 = 1240

I NEED AN ANSWER ASAP A surveyor finds the angle of elevation to the top of a building to be 75°. He is 20 meters from the base of the building. How tall is the building?
Answer: 74.6
we draw a right triangle ABC, have: ∠ABC = 90°, AB = 20 and ∠BAC = 75°, the height of the building is BC
we also have: tan 75° = BC/AB = BC/20
=> BC = tan 75°. 20 = 40 + 20√3 ≈ 74.6
Step-by-step explanation:
need help please, ASAP
Answer:
BC ≅ YX and ∠A ≅ ∠X

Select the slope-intercept form of an equation for a line with y-intercept –5 and slope 2. A. x = 2x + 5 B. y = 2x – 5 C. y = 5x – 2 D. y = –5x + 2
Answer:
y=2x-5
Step-by-step explanation:
slope intercept form is y=mx+b
m=slope
b=y-intercept
Answer: y = 2x - 5
slope-intercept form ⇒ y = mx + b
⇒ where mx is the slope,
⇒ b is the y-intercept
⇒According to the question;
mx which is the slope = 2
b the y-intercept = -5
∴ the equation is

A square garden has an area of 53.29 square meters. What is the length of each side of the garden?
1) 3.8m
2) 7.3m
3) 13.3m
4) 26.6m
Answer:
7.3m
Step-by-step explanation:
Area is l * w
The length and width of a square are the same, so that means we can use square root for this problem.
The square root of 53.29 is 7.3
7.3*7.3 = 53.29 (<- to double check)

Twice Sam's age added to half her mother's age is 48. Three times her age less one third of her
mother's age is 33. How old are Sam and her mother?
Answer:
Sam is 15 and her mother is 36
Step-by-step explanation:
Let Sam's age be x and her mother's age by y
We can figure out Sam and her mother's age by representing these scenarios using equations with variables and solving the system using elimination
2x+y/2=48
3x-1/3y=33
You start by making all the numbers in both the equations whole
2(2x+y/2=48)
3(3x-1/3y=33)
Becomes:
4x+y=96
9x-y=99
Add together to eliminate y
13x/13=195/13
x=15
Now that we have x we can plug the value into the x in the equations to give us the y-value
2x15+y/2=48
30+y/2=48
30+y/2-30=48-30
y/2=18
2 X y/2=18 X 2
y=36
Therefore x=15 and y=36

Help please im very lost
Answer:
pretty sure it is zero
Step-by-step explanation:
There are two x's of the same value so presumably the line is vertical which would mean it has no slope and could only be described as zero
Answer:
Step-by-step explanation:
Find the slope. Use m = y2-y1/x2-x1 form
So, -4-(-17)/-6-(-6)
This = 13/0
Which = undefined.
The slope is undefined.
