8.75 feet
Step by step:Given that a 12 foot ladder leans against a building seven feet above the ground.
By using trigonometry ratio, the angle between the ladder and the ground will be
SinØ = opposite/ hypothenus
SinØ = 7 / 12
SinØ = 0.58333
Ø = Sin^-1(0.58333)
Ø = 35.69 degree
At what height would an 15 foot ladder touch the building if both ladders form the same angle with the ground?
Using the same trigonometric ratios
SinØ = opposite/hypothenus
Sin 35.69 = opposite/ 15
Cross multiply
Opposite = 15 × sin 35.69
Opposite = 8.75 feet
Therefore, the ladder will touch the building if both ladders form the same angle with the ground at height 8.75 feet.
A countertop is 11 feet long and 4 fee t wide.
What is the area of the countertop in square meters? Use the conversion 1 foot = 0.305 meter. Round your
final answer to 2 decimal place
Answer:
4.09m^2
Step-by-step explanation:
A countertop is 11 feet long and 4 fee t wide.
Using the conversion
1foot = 0.305 meter
11fet = 11(0.305)
11feet = 3.355 m
4 feet= 4 * 0.305
4feet = 1.22m
Area of the countertop = Length * Width
Area of the countertop = 3.355 * 1.22
Area of the countertop = 4.0931m^2
Hence the required area is 4.09m^2 to 2 decimal places

Solve d.
d ÷ 5/6 = 3/4
Write your answer as a fraction or as a whole or mixed number.
d =
Answer:
d = 9/10
Step-by-step explanation:
Hi,
d divided by 5/6 = 3/4
You can't divide fractions, instead, you flip the fraction and multiply. So, in this case, you would flip 5/6 to get 6/5 and multiply it by 3/4 to get d.
d ÷ 5/6 = 3/4
Multiply both sides by 6/5 (remember to flip)
d = 3/4 x 6/5
(when multiplying fractions, you can multiply straight across)
d = 18/20
(simplify - both numbers can be divided by 2)
d = 9/10
Hope this helps :)
Answer:
d = 5/8
Step-by-step explanation:
Mulitply by the reciprocal
= d x 6/5 = 3/4
Reorder the terms
=6/5d = 3/4
Multiply both sides
Solution
d = 5/8
Alternate form
d = 0.625

Step-by-step explanation:
7x - 4y = -5 ordered pair
Answer:
Step-by-step explanation:
You may invent a value for x, substitute that value into the given equation and thereby calculate y:
If 7x - 4y = -5 and x = 0, then -4y = -5 and y = 5/4. The corresponding ordered pair is (0, 5/4). Other x values may be chosen at random and the same operations performed so as to find other possible ordered pairs corresponding to 7x -4y = 5.
Show all your work! Thank you!
Answer: B
Step-by-step explanation:
x = van

12x + 9y = 456
1x + 2y = 83
(Simplify equations)
9y = -12x + 456
y = -1.3x + 456/9
2y = -x + 83
y = -1/2x + 41.5
(Find x)
-1.3x + (456/9) = -.5x + 41.5
0.8x = 9.16
(Round)
x = 11
(Find y by plugging x in)
y = -1/2(11) + 41.5
y = -5.5 + 41.5
y = 36
(Check)
12(11) + 9(36) = 456
132 + 324 = 456
1(11) + 2(36) = 83
11 + 72 = 83
