A 12-foot ladder rest against the side of a house. The base of the ladder is 3 feet away from the side of the house. How high above the ground is the top of the ladder? Round to the nearest tenth of a foot.I would love for someone to help me real quick I am in summer school right now and only have 2 hours left and i have to do a lot of retests. So if anyone could help me in the next 5 minutes or so that would be nice.
Thanks
Answers
from base of triangle to wall=a
from floor to top of ladder on wall=b
legnth of ladder=c
legnth=12=c
base is 3 feet away=a
use pythagorean theorem
a^2+b^2=c^2
3^2+b^2=12^2
9+b^2=144
subtract 9
b^2=135
square root both sides
b=√135=3√15
the height is 3√15 feet

The triangle is rotated in a clockwise direction, as per the given conditions.
What is the triangle?
The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
Here,
It seems to be questioned is incomplete, we assume that the direction of rotation that maps triangle BCD to triangle B’C’D’ on a coordinate plane from quadrant 2 to quadrant 1 is about the origin. As rotation from quadrat 2 to one about origin represents the clockwise direction.
Thus, the triangle is rotated in a clockwise direction, as per the given conditions.

Answer:
The total number of employees company have now are 531 .
Step-by-step explanation:
As given
A manufacturing company with 450 employees begins a new product line and must increase their number of employees by 18%.
18% is written in the decimal form .
= 0.18
Increase in number of employees = 0.18 × Number of employees in company .
= 0.18 × 450
= 81
Total number of employees company have now = Number of employees + Increase in number of employees
= 450 + 81
= 531
Therefore the total number of employees company have now are 531 .
So the equation would look like:
450(.18)=81
Which you then add:
450+81= 531
So 531 is your total!

The cost of the sweater is given by the equation A = $ 40.69
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total cost of the sweater be represented as A
Now , the equation will be
The cost of sweater without discount and sales tax = $ 47.99
The discount percentage = 20 %
The cost of sweater after discount = 47.99 - ( 20/100 ) x 47.99
On simplifying the equation , we get
The cost of sweater after discount = 47.99 - 9.598
The cost of sweater after discount = $ 38.392
Now , the percentage of sales tax = 6 %
The cost of sweater after sales tax = 38.392 + ( 6/100 ) x 38.392
On simplifying the equation , we get
The cost of sweater after sales tax = 38.392 + 2.30352
The cost of sweater after sales tax = $ 40.695
Therefore , the value of A is $ 40.69
Hence , the final cost of the sweater is $ 40.69

so multiply %20 by the cost or .2(47.99)=9.598 which rounds to 9.60 meaning she still paid $38.39
Then calculate sales tax by multiplying her clearance price by %6 and adding it on the cost
.06(38.39)= 2.3034 which rounds to $2.30 in tax.
Add that onto the clearance price 38.39+2.30=$40.69
So her total cost was $40.69

Multiply the number outside the parenthesis(4) with the numbers inside the parenthesis(6 and -1)
24x-4=120
Add 4 to both sides
24x=124
Divide both sides by 24
Final Answer: x= 5.1667 or 5 1667/10,000
