Answer:
AE = 60 units
Step-by-step explanation:
GE is one third the length of AE so...
GE = 1/3(AE)
20 = 1/3x
3(20) = (1/3x)3/1
60 = x
x = 60
AE = 60 units

What is equivalent to 4/7=12/x-3
Answer:
x=84/25
Step-by-step explanation:
4/7=12/x -3
1. Add 3 to both sides of the equation
4/7+3=12/x- 3+3
2. Simplify
25/7=12/x
3. Multiply all terms by the same value
x . 25/7 =x . 12/x
4. Simplify
25x/7=12
5. Multiply all terms by the same value
7 . 25x/7= 7 . 12
Solution: x=84/25

The opposite of -4:
The opposite of 8:
The opposite of the opposite of – 2:
Answer:
1. 42. -83. -2Step-by-step explanation:
To find the opposite of a certain number, divide it to -1 or simply change its sign. For negative numbers, their opposites are positive. For positive numbers, their opposites are negative.
For numbers 1 and 2, change their sign to find their opposite numbers. For numbers 3, it is still the same. “The opposite of the opposite of -2.” The opposite of -2 is 2, and the opposite of 2 is -2. The opposite contradicts the following words, so it will be the same.

Given circle with diameter AB. Find the angle of C
Answer:
90°
Step-by-step explanation:
Since AB is the diameter of the circle with center O and C is any point on the circle.
So, ACB is a semicircular arc.
Angle inscribed in a semicircle is right angle.
[tex]\therefore \measuredangle C =90\degree [/tex]

Help please !!! I never understood this
Step-by-step explanation:
As x approaches negative infinity, h(x) approaches positive infinity / negative infinity, which is an indeterminate form.
Therefore we use L'Hospital's Rule:
Derivative = 30x⁵ / 7x⁶ = 30 / (7x)
As x approaches negative infinity, 30 / (7x) approaches 0, and it comes from below because it is a rational graph with positive coefficient.
Hence the anewer is C.
Kareem cannot decide which of two washing machines to buy. The selling price of each is 660$. The first is marked down by 40%. The second is marked down by 20% with an additional 30% off. Find the sale price of each washing machine. Use pencil and paper. Explain why should buy the first washing machine rather than the second if the machines are the same except for the selling price.
PLS HELP ME
Answer:
See explanation
Step-by-step explanation:
The selling price is $495.
The first washing machine:
- is marked down by 30%
$495 - 100%
$x - 100% - 30% = 70%
Find the value of x:
The second washing machine:
- is marked down by 20% with an additional 10% off
$495 - 100%
$y - 100% - 20% = 80%
Find y:
[tex]y=$495 . 0.8 = $396[/tex]
Now,
$396 - 100%
$z - 100% - 10% = 90%
Find z:
[tex]z=$396.0.9 = $356.40 = $356[/tex]
Thus, the sale price of the first washing machine is $347 and the sale price of the second washing machine is $356. The second machine is more expensive.

What is the magnitude (size) of -9.1?
O A. 9.1, because |-9.11 = 9.1
OB. 0.91, because |-9.11 = 0.91
O C.-9.1, because |-9.11 = 9.1
O D. 9.1, because |-9.11 = -9.1
Given:
Number = -9.1
To find:
The magnitude (size) of given number.
Solution:
We know that, magnitude of a number is the absolute value of that number.
So, magnitude of -9.1 is
[tex]|-9.1|=9.1[/tex]
Because, absolute value of a number is always positive.
Magnitude of -9.1 is 9.1 because [tex]|-9.1|=9.1[/tex].
Therefore, the correct option is A.
Answer:
The answer is A

Natasha wants to order some party favors for her birthday party. She orders them from an online store, where they cost $11 each and there is a shipping charge of $6 for the entire order. If Natasha can spend no more than $50, which inequality represents how many party favors, x, she can buy?
Answer:
This answer is B.
Step-by-step explanation:
First we need to figure it out on our own, then plug into the inequalities to see which one works.
11x+6≤50
subtract 6 from both sides
11x≤44
divide from 11 on both sides
x≤4 so she can buy 4 party favors or less.
A: it cannot be A since it says the party favors are greater than 4
B: This is the correct answer.
C: 6 is not an answer
D: 6 is not an answer

What is the slope of y=2+3.5x pls answer
Answer:
slope = 3.5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 2 + 3.5x OR y = 3.5x + 2 ← is in slope- intercept form
with slope m = 3.5
If the following relation is a function, which ordered pair could be the missing point?
Hi there.
The answer is B choice.
Explanation:
A function is a set of relation with no repetitive domains.
Here is an example of being a function and relation.
~ Function ~
Given the relation r = {(1,1),(2,4),(3,9),(4,16)}
As you see, there are no repetitive domains. Thus this relation is a function.
~ Relation ~
Given r = {(1,1),(1,2),(2,6),(3,28)}
As you see, there are the repetitive domains in this relation. And that is x = 1. Therefore, this relation is not a function but only a relation.

7 (x + 2) -5 = 30
Answer:
x = 3
Step-by-step explanation:
Given
7(x + 2) - 5 = 30 ( add 5 to both sides )
7(x + 2) = 35 ( divide both sides by 7 )
x + 2 = 5 ( subtract 2 from both sides )

For what real values of does the quadratic 12x^2+k*x+27=0 have nonreal roots
Step-by-step explanation:
Discriminant : k² - 4(12)(27) < 0
So k² - 1296 < 0, -36 < k < 36.
Answer:
If a quadratic has nonreal roots, then the discriminant . b^2 - 4ac
Plug in the values for b, a, and c into this equation to get . k^2-4 *12*27 < 0
Rearrange to get . k^2 < *12*27
Now factorize 4*12*27 and solve to get - 36 < k<26

Nick opens a savings account with $50.Each week after,he deposits $15.In how many weeks will he have saved$500?
Answer: 31 weeks
Step-by-step explanation:
50 + 15w = 500
w = weeks
50 + 15w = 500
-50
15w = 450
/15
w = 30
So 30 weeks after the first 50 makes 31
Answer:
30 weeks
Step-by-step explanation:
if his account has 50$ in the first place, this means we subtract 50$ from 500$
500-50= 450
now we have 450, we divide 450 to 15(the money he deposits per week).
450÷15=30
the answer is 30 weeks

A study was conducted to analyze the effects on deer
population in a particular area.Let f be an exponential
function that gives the population of deer t years after
the study began.
If f(t) = a • bt and the population is increasing, select
the two statements that must be true.
(No joke answers)
Answer if you know^
Answer:
Options (2) and (3)
Step-by-step explanation:
If 'f' is an exponential function,
f(t) = [tex]a.b^t[/tex]
Or we can rewrite the function as,
f(t) = [tex]a.(1+r)^t[/tex]
Here 'r' = rate of increase in the population.
a = Initial population
If the rate is positive, population will be increasing [(1 + r) > 1]
If the rate is negative, population will be decreasing [0 < (1 - r) < 1]
For increase in the population b > 1
For decrease in the population 0 < b < 1
And initial population (a) should be greater than 0.
Therefore, Options (2) and (3) will be the correct options.
