Answer:
1)80%
2)210%
3)65%
4)105%
Answer:
80%
210%
65%
105%
Step-by-step explanation:
To solve for each of these equations, let's make them fractions first. The denominator will be 20 since that was the goal.
Elena did [tex]\frac{16}{20}[/tex] pushps.
Jada did [tex]\frac{42}{20\\}[/tex] pushups.
Lin did [tex]\frac{13}{20}[/tex] pushups.
Andre did [tex]\frac{21}{20}[/tex] pushups.
To convert this to percentages, let's multiply each by fraction by [tex]\frac{5}{5}[/tex]. This will give us a denominator of 100. The denominator will represent the percentage.
Elena did [tex]\frac{16}{20}[/tex] × [tex]\frac{5}{5}[/tex] = [tex]\frac{80}{100}[/tex] pushps. Elena did 80 percent of the pushups.
Jada did [tex]\frac{42}{20\\}[/tex] × [tex]\frac{5}{5}[/tex] = [tex]\frac{210}{100}[/tex] pushups. Jada did 210 percent of the pushups.
Lin did [tex]\frac{13}{20}[/tex] × [tex]\frac{5}{5}[/tex] = [tex]\frac{65}{100}[/tex] pushups. Lin did 65 percent of the pushups.
Andre did [tex]\frac{21}{20}[/tex] × [tex]\frac{5}{5}[/tex] = [tex]\frac{105}{100}[/tex] pushups. Andre did 105 percent of the pushups.

(Choice A)
Perimeter
(Choice B)
Length
(Choice C)
Area
Answer:
(Choice A) Perimeter
Step-by-step explanation:
It can't be the length, because it states in the question that the length is 7 m
and it can't be the area because lw = 7(8) = 56 is the area.

Mr. Bruce has some clay with a mass of 24 kilograms. If he puts the same amount of clay into 6 bags, how many grams of clay are in each bag? I NEED THE EXPLANATION
Answer:
4000grams in each bag
Step-by-step explanation:
Assume he put x amount of clay into each bag, he then put 6x into 6 bags.(since the question didn’t mention, I assume he put every clay he has into the bags)
6x=24kg
x=4kg
Since the question is asking for grams not kilograms:

A gear with a diameter of 12.0 inches makes 35 revolutions every three minutes. Find the linear and angular velocities of a point on the outer edge of the gear. Give your answers in both exact and approximate forms.
Answer:
Angular velocity: [tex]\omega = \frac{7\pi}{18} \,\frac{rad}{s}[/tex] ([tex]1.222\,\frac{rad}{s}[/tex])
Linear velocity: [tex]v = \frac{14\pi}{3}\,\frac{m}{s}[/tex] ([tex]14.661\,\frac{m}{s}[/tex])
Step-by-step explanation:
The gear experiments a pure rotation with axis passing through its center, the angular ([tex]\omega[/tex]), in radians per second, and linear velocities ([tex]v[/tex]), in inches per second, of a point on the outer edge of the element are, respectively:
[tex]\omega = \frac{2\pi}{60}\cdot \dot n[/tex] (1)
[tex]v = R\cdot \omega[/tex] (2)
Where:
[tex]\dot n[/tex] - Rotation rate, in revolutions per minute.
[tex]R[/tex] - Radius of the gear, in inches.
If we know that [tex]\dot n = \frac{35}{3}\,\frac{rev}{min}[/tex] and [tex]R = 12\,in[/tex], then the linear and angular velocities of the gear are, respectively:
[tex]\omega = \frac{2\pi}{60}\cdot \dot n[/tex]
[tex]\omega = \frac{7\pi}{18} \,\frac{rad}{s}[/tex] ([tex]1.222\,\frac{rad}{s}[/tex])
[tex]v = R\cdot \omega[/tex]
[tex]v = \frac{14\pi}{3}\,\frac{m}{s}[/tex] ([tex]14.661\,\frac{m}{s}[/tex])

Answer:

Step-by-step explanation:
When x=6
f(6) =(6)2-2(6)=12-12=0
Answer:
firstly... substitute x for 6 in the equation..
=(6)2 -2(6)
=12-12=0
For each equation, find y when x=-3. Then find x when y = 2
1. y = 6x + 8
⬇ Hey, the answer is down below! :) ⬇
For y: x = -3
For y it stays the same.
For x: y = 2
For x it stays the same too.
For 1.): [tex]x = \frac{1}{6}y + \frac{-4}{3}[/tex]
Step-by-step explanation:
For y there is no step-by-step explanation unfortunately.
For x there isn't a step-by-step explanation too unfortunately.
⬇ For 1.) there is a step-by-step explanation! ⬇
For step 1 we should flip the equations.
6x + 8 = y
For step 2 we should add -8 to both sides.
6x + 8 + − 8 = y + −8
= 6x = y − 8
For step 3 we should divide both sides by 6.
[tex]\frac{6x}{6} = \frac{y - 8}{6}[/tex]
= x = [tex]x = \frac{1}{6}y + \frac{-4}{3}[/tex]
In result we should have [tex]x = \frac{1}{6}y + \frac{-4}{3}[/tex] as the answer!
Find the surface area of the cone.Use 3.14 for pi and round your answer to the nearest hundredth
Answer:
145.0 cm^2
Step-by-step explanation:
Given data
r= 4cm
l= 5cm
h=??
Apply Pythagoras theorem to find h we have
h^2= 4^2+5^2
h^2= 16+25
h^2= 41
h=√41
h= 6.4cm
Substitute into the formula for the surface area of cone
A=πr(r+√h^2+r^2)
A=3.14*4(4+√6.4^2+4^2)
A=12.56(4+√40.96+16)
A=12.56(4+√56.96)
A=12.56(4+7.547)
A=12.56*11.547
A=145.0 cm^2
What is the distance between (-4, 8) and (12, 8) on the coordinate plane? A 16 units B 8 units C 0 units D 4 units
Answer:
16 units
Step-by-step explanation:
We need to find the distance between (-4, 8) and (12, 8) on the coordinate plane.
We know that the distance between two points on the coordinate plane is given by :
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Put x₁ = -4, x₂ = 12, y₁ = 8 and y₂ = 8
So,
[tex]D=\sqrt{(12-(-4))^2+(8-8)^2}\\\\=16\ units[/tex]
So, the distance between the two points is equal to 16 units.

- Scores on an exam are normally distributed woth a population standard deviation of 5.6. A random sample of 40 scores on the exam has a mean of 32 estimate the population mean with - A) 80% confidence - B) 90% - C) 98%
Answer: i think i got b or c onr of them are correct :)
Step-by-step explanation:
The estimated population mean with
80% confidence = [30.856, 33.135]
90% confidence = [30.543, 33.456]
98% confidence = [29.94, 34.06]
What is confidence interval?For a population with unknown mean and known standard deviation , a confidence interval for the population mean, based on a simple random sample of size n, is [tex]\bar x +_{-}z^{*}\frac{\sigma}{\sqrt{n} }[/tex] , where z* is the upper (1-C)/2 critical value for the standard normal distribution.
Population standard deviation = 5.6
Sample mean = 32
Sample size = 40
Given confidence level = 80%
[tex]z^{*}[/tex] at 80% confidence level = 1.28
Upper confidence interval = 33.135
Lower confidence interval = 30.865
Population mean lies between [30.856, 33.135] at 80% confidence level.
Given confidence level = 90%
[tex]z^{*}[/tex] at 90% confidence level = 1.65
Upper confidence interval =33.456
Lower confidence interval = 30.543
Population mean lies between [30.543, 33.456] at 90% confidence level.
Given confidence level = 98%
[tex]z^{*}[/tex] at 98% confidence level = 1.65
Upper confidence interval = 34.06
Lower confidence interval = 29.94
Population mean lies between [29.94, 34.06] at 98% confidence level.

A man is three times as old as his daughter. If the difference in their ages is 36 years, find the ages of the father and daughter.
Answer:
man's age = 54
daughter's age = 18
Step-by-step explanation:
x = man's age
y = daughters age
x = 3y
x - y = 36
substitute for x:
3y -y = 36
2y = 36
y = 18
x = 54
If a man has a daughter who is three times his age. The father and daughter will be 54 and 18, respectively, assuming their ages are 36 years distant.
What is an equation?Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation. The two expressions on each side of the equals sign are referred to as the "left-hand side" and "right-hand side" of the equation.
It is given that, A man is three times as old as his daughter. If the difference in their ages is 36 years,
We have to find the ages of the father and daughter.
Suppose the age of the father and daughter will be x and y respectively.
If the man is three times as old as his daughter,
x = 3y
If the difference in their ages is 36 years
x - y = 36
Put the value of x as,
3y -y = 36
2y = 36
y = 18
x = 54
Thus, if a man has a daughter who is three times his age. The father and daughter will be 54 and 18, respectively, assuming their ages are 36 years distant.
