Taylor tried to solve a math equation step by step
7(y+4.5) = 32.5
7y + 4.5 = 32.5 (step one)
7y = 28 (step two)
y = 4 (step three)
In which step did taylor make a mistake or did she not make any mistakes?
Answer:
Step one - she didn't multiply the 4.5 with the 7

A 13tf.ladder is leaning against the house. The top of the ladder touches the house at 10 feet above the ground.How far away is the bottom of the ladder from the house?(draw yourself a picture and label it)
Answer:
Step-by-step explanation:
I believe youd be using pythagorean theorem here. I hope this helps
The bottom of the ladder from the house is 8.30 feet away.
What is Pythagoras Theorem?The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
Given:
H= 13 feet
P= 10 feet
Using Pythagoras Theorem
B = √ H² - P²
H = √13² - 10²
B= √ 169- 100
B= √69
B= 8.30 feet
Hence, the bottom of the ladder from the house is 8.30 feet away.

The value of a piece of land deprecates at a rate of 0.60 per year after three years land is worth 2500 what was the original value of the building
Well, there is actually a formula for this kind of exercises:
n is the price the land had in the third year year
2500=n-nx0.6
2500=n(1-0.6)
2500=nx0.4
n=2500:0.4
n=6250
m is the price the land had in the second year
6250=m-mx0.6
6250=m(1-0.6)
6250=nx0.4
p=6250:0.4
p=15625
p is the price the land had in the first year
15625=p-px0.6
15625=p(1-0.6)
15625=px0.4
p=15625:0.4
p=39,062.5 <- this should be your answer. Hope this helps.
Cayden is 6 years older than Kaylee. If Cayden is y years old, and Kaylee is x years old, which of the following equations represents the relationship between their ages?
Answer: x + 6 = y OR y = x + 6 (same equation in different format)
Step-by-step explanation: If x represents Kaylee’s age, and Cayden is 6 years older, then you must always add 6 to Kaylee’s age in order to find Cayden’s age (y).
Answer:
x + 6 = y or y - 6 = x
Step-by-step explanation:
If you know that Cayden is 6 years older than Kaylee, then x (Kaylee's age) + 6 years = y (Cayden's age). You don't know the ages of them but you still know how much older Cayden is than Kaylee.
It can also be y - 6 = x because it shows that if you subtract 6 years from Cayden's age, you get Kaylee's age.

The sports shop has 30 part-time employees and 20 full-time employees. What percentage of the employees at the sports shop work part-time?
Answer:
the percentage of the employees at sports shop work part time is 60%
Step-by-step explanation:
The computation of percentage of the employees at sports shop work part time is shown below:
= Part time ÷ total employees
= 30 ÷ (20 + 30)
= 30 ÷ 50
= 3 ÷ 5
= 60%
Hence, the percentage of the employees at sports shop work part time is 60%

MARKING YOU BRAINLIST AND 5 STARS! A tire from Karen's car is shown below. Which is the closest to the distance traveled, in feet, after 3 full rotations of the tire? The diameter is 2 feet, by the way.
Answer:
18.86 feet
Step-by-step explanation:
One rotation of the tire is equal to the circumference of the tire
The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where
π = 22/7
d = diameter
The size of one revolution = 2 x 22/7 = 44/7 feet
The distance covered in one rotation of the tire is 44/7 feet
The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet

The nitro-methane fuel mixture used to power some experimental cars is 96% nitrogen dioxide and 4% methane. How many gallons of methane are needed to fill a 15-gallone fuel tank?
Answer:
0.6 gallons of methane are needed to fill a 15-gallone fuel tank.
Step-by-step explanation:
Methane is 4% of the total amount.
The total amount is of 15 gallons. So
0.04*15 = 0.4*1.5 = 0.6
0.6 gallons of methane are needed to fill a 15-gallone fuel tank.

Plz help ASAP with circles
Answer:
c. 11
Step-by-step explanation:
By the property of intersecting secants outside of a circle, we have:
[tex] m\angle R = \frac{1}{2} \times (175\degree - 75\degree) [/tex]
[tex] m\angle R = \frac{1}{2} \times 100\degree [/tex]
[tex] (4x+6)\degree = 50\degree [/tex]
4x + 6 = 50
4x = 50 - 6
4x = 44
[tex] x = \frac{44}{4} [/tex]
x = 11

ez pts someebody help find the equation axis of symmetry of y=-2(x-3)^2 +4
Answer:
x = 3Step-by-step explanation:
Given function:
y= -2(x-3)² +4Vertex form:
y = a(x − h)² + kAxis of symmetry is the line parallel to y-axis and passes through vertex. The x-coordinate of the vertex is determined by the value of h in the above equation.
We have h = 3 as per given equation for the function.
Axis of symmetry is the line x = 3
