HELP ME PLEASE !! Mao changes the incline angle on his treadmill from 0° to 5°. If the walking surface of the treadmill is 5
feet long, how many inches did Mao raise the end of the treadmill from the floor to the nearest tenth of an inch?
Answer:
5.2 inches
Step-by-step explanation:
We can use trigonometry for this. We know that sin = opposite/hypotenuse so opposite = hypotenuse sin. If we want the answer in inches we set the hypotenuse to inches 5 ft = 60 inches. We just use 60 sin 5 degrees to get to our answer.
Sandra has a $20 itunes gift card and spends $3 each month. Which of the following functions models how much money Sandra has on her gift card after x months?

Find the value of x
A. 5 square root 2/2
B 5
C 10
D 10 square root 2
Answer:
The answer is C
Step-by-step explanation:
That side with the 5 is equal to 7.071067812.... (irrational number)
To get x you need to use the equation a^2 + b^2 = c^2
A^2 and B^2 will both be the same thing. The red line indicates they are the exact same length.
7.071037812.... ^2 is 50
Now your equation would be 50+50= c^2 (which is the same as x^2)
100= c^2 is simplified by finding the square root of 100.
Your answer is 10 for side X because the square root of 100 is 10.

The hypotenuse x of the right triangle is (c) 10
Finding the hypotenuse, x of the right triangleFrom the question, we have the following parameters that can be used in our computation:
The right triangle
Where, we have
Leg a = 5√2
Leg b = 5√2
The hypotenuse of the right triangle can be calculated using the following Pythagoras theorem
h² = a² + b²
Using the above as a guide, we have the following:
x² = (5√2)² + (5√2)²
Evaluate
x² = 100
Take the square roots
x = 10
Hence, the hypotenuse of the right triangle is (c) 10

Dwayne's garden is triangle-shaped with two equal sides and a third side that is 4 ft more than the length of an equal side. If the perimeter is 49 ft, how long is each side?
Which equation represents this?
2x = 49
2x + 4 = 49
3x = 49
3x + 4 = 49
Answer:
2x = 49
=x=24.5
if 2x + 4=49
49-4/2=x
x=22.5
if 3x + 4 =49
x=45/3=15
3x + 4 belongs it

Answer:
2x = 49
=x=24.5
if 2x + 4=49
49-4/2=x
x=22.5

Answer:
x = 3/10
Step-by-step explanation:
Given
6x +3 +4x = 1/2(9 +10x)
We can collect term, then multiply by 2.
10x + 3 = (1/2)(9 +10x)
20x + 6 = 10x + 9 . . . . . . . multiply by 2
10x = 3 . . . . . . . . . . . . . . . . subtract (6+10x)
x = 3/10 . . . . . . . . . . . . . . . divide by 10

Alex is y years old. Bella is 4 years older than him .Carla is double Alex's age. The sum total of their age is 32
Form and solve an equation to work out the ages of the three children
Answer:
Alex is 7, Bella is 11, and Carla is 14
Step-by-step explanation:
Equation is 32=y+2y+(y+4)
To solve:
First combine like terms (the y's)
32=4y+4
Subtract 4 from both sides
28=4y
Divide both sides by 4 to get y alone
7 =y (Alex's age)
Bella is 4 years older than Alex so 7+4 = 11
Carla is 2 times older than Alex so 2 • 7 = 14
Their ages are supposed to add up to 32.
7+11+14
18+14
32
