A ladder is leaning against a building so that the distance from the ground to the top of the ladder is 3 feet less than the length of the ladder. Find the length of the ladder if the distance from the bottom of the ladder to the building is 9 feet.
Answer:
15 ft
Step-by-step explanation:
This is another classic case of Pythagoras theorem. To start with, let's assume that the length of the ladder we're looking for is x
We're told that the height of the building the ladder is leaning on is, x - 3
Also we're told that the distance at an adjacent from the ladder is 9 ft.
If we use Pythagoras theorem, we have
x² = (x - 3)² + 9²
x² = x² - 6x + 9 + 81
On rearranging, we have
x² - x² = -6x + 90
6x = 90
x = 90 / 6
x = 15 ft
Therefore, the length of the ladder is found to be 15 ft

what is the measure of angle b? 47, c, a , b
Answer:
b=47
47+a=180
a=180-47
a=133
c+b=180(but b is equal to 47)
c+47=180
c=180-47
c=133
I hope this help

You have a new 10-day workout routine. You want to do 10 sets of 10 sit-ups each
day. Which expression shows the total number of sit-ups you do in 10 days?
CLEAR
CHECK
103
10 + 10 + 10
102
3 x 10
Answer:
10²
Step-by-step explanation:
Another way of phrasing "10 sets of 10 sit-ups" is "10 sit-ups, 10 times," or mathematically, 10 x 10. Another way of writing repeated multiplication is through exponents. Since we have 2 10's multiplied together, we can rewrite our expression as 10².
Answer:
10 to the power of 2
Step-by-step explanation:
10 to the power of 2 is 100 because you multiply 10x10 2 times Hope this helps
Angad, Gavin & Nick share some money in the ratio 3 : 4 : 1. In total, Angad and Nick receive £32. How much does Gavin get?
Answer:
$32
Step-by-step explanation:
There are two ways of determining the answer
1. the fast method
the sum of Angad and Nick's ratio is 3 + 1 = 4
this is equal to the ratio of Gavin's earnings. It is also 4
So if Angad and Nick receive £32, Gavin would also receive $32 since the ratios are equal.
2. Longer method
Let the total amount received by the 3 of them = a
Sum of ratios = 3 + 4 + 1 = 8
the equation representing the amount received by Angad and Nick is
(4/8) x a = $32
Divide both sides by 8/4 and find a
a = $64
the total amount received is $64
amount received by Gavin =
(4/8) x 64 = $32

A. 30 -1 =7
B.
32 = 8
1) How can we get Equation B from Equation A?
Answer:
you +1 on each side
Step-by-step explanation:
a is 30-1=7
b is 32=8
to get from "a" to "b" you simply add one on both sides
32 - 1 = 7
+ 1 +1
------------------
32=8

A taxi charges $1.75 plus a free of $0.75 for each mile traveled the total cost of a ride without a tip is, $4.75. How many miles in the trip Use m for the number of miles traveled.
Answer:
4 miles traveled
Step-by-step explanation:
1.75 + 0.75m = 4.75.
4.75 - 1.75 = 3
3 ÷ 0.75 = 4
is the ordered pair (4,16) a solution to the equation y=3x+4; (4,16)
Answer:

Answer:
a)
The point that is equidistant to all sides of a triangle is called the incenter.
The incenter is located at the intersection of bisectors of the interior angles of a triangle.
b)
The point that is equidistant to all vertices of a triangle is called the circumcenter.
The circumcenter is located at the intersection of perpendicular bisectors of the sides of a triangle.
c)
See the attachment
The blue lines and their intersection shows the incenter.
The red lines and their intersection shows the circumcenter.
As we see the red point- the circumcenter is closer to vertex B.

In a hydraulic lift, a 1400 N force is applied to a 0.5 m2 piston. Calculate the minimum surface area of the large piston to lift 5000 N.
Answer:
1.8m^2 approx
Step-by-step explanation:
Given data
P1= 1400N
A1=0.5m^2
P2=5000 N
A2=??
Let us apply the formula to calculate the Area A2
P1/A1= P2/A2
substitute
1400/0.5= 5000/A2
cross multiply
1400*A2= 5000*0.5
1400*A2= 2500
A2= 2500/1400
A2= 1.78
Hence the Area is 1.8m^2 approx

Answer:
C. 12 m wide
Step-by-step explanation:
We note that the difference in dimensions is 4 m. This difference will remain the same when both sides are increased by the same amount. If x represents the short side, then the larger area is ...
x(x +4) = 192
x^2 +4x + 4 = 196 . . . . add 4 to complete the square
(x +2)² = 14²
x = 14 -2 = 12 . . . . . . . . positive square root
The new garden will be 12 m wide.

Answer:
Step-by-step explanation:
We know the area of a triangle is B*H/2. For Triangle ABC, the area is 75. So the equation formed is:
15*h/2 = 75
15*h = 150
h = 10.
Now we know the height for the bigger triangle is 10. Since the scale factor from 15 --> 3 is 5, the height for triangle EFG is 2 because 10 divided by 5 is 2. Since we now know the height of the triangle is 2 and the base is 3, we can form the equation:
3*2/2 = Area
6/2 = Area
3 = Area
We know the area is 3. The key thing was we didn't divide triangle ABC with 5 because the area would not be the same. We must use the equation and from this we will get the correct area.
Answer:
Step-by-step explanation:
It is 15.
(15×x) /2 =75
×2. ×2
X×15=150
/15. /15
X=10
(3×x) /2 =area of triangle
(3×10) /2
30/2
15= area of triangle

Caroline earns $106.25 for 5 hours of work. If she makes a constant hourly wage, which table represents the relationship between the number of hours she works and her total earnings?
Answer: A
Step-by-step explanation:
Cole buys a new laptop for $335. He makes a down payment for $50, then makes 6 equal monthly payments ‘p'. Write an equation that represents the situation
Given:
Total amount of new laptop = $335
Down payment = $50
Number of equal monthly payments = 6
Amount of monthly payments = [tex]p[/tex]
To find:
The equation that represents the given situation.
Solution:
We have,
Amount of monthly payments = [tex]p[/tex]
Total amount for 6 equal monthly payments = [tex]6p[/tex]
We know that,
Total amount = Down payment + Total amount of all monthly payments
[tex]335=50+6p[/tex]
Therefore, the required equation for the given situation is [tex]335=50+6p[/tex].
