Emily sold 147 candles for a fundraiser. If she sold 70% of the total number of candles sold for the fundraiser, what is the total number of candles sold for the fundraiser?
Solution:
Candles Emily sold=70% of Total Number of Candles
Emily sold 147 candles.
So, We have,
147=70% of Total Number Of Candles
Let, Total Number Of Candles=x
147=70% of x
147=[tex] \frac{70}{100} [/tex] *x
147=[tex] \frac{70x}{100} [/tex]
Let us multiply by 100 on both sides
147*100=[tex] \frac{70x*100}{100} [/tex]
14700=[tex] \frac{70x*1}{1} [/tex]
14700=70x
To solve for x, Let us divide by 70 on both sides
[tex] \frac{70x}{70}=\frac{14700}{70} [/tex]
x=14700/70
x=210
Total Number of Candles=210
YO! I WILL MAKE YOU LOOK GOOD IF YOU ANSWER MY QUESTION!!!!!!!
Answers
Since the turning points are two and the first line came from the negative side and the second is in the positive side, so there for if you will multiple it negative times positive will give you negative.
This is the hint that this is an odd degree. Since if you raise thw power to an odd degree, it wi give you a negative answer. So it will have two different sides, points in the negative and points on the positive side.
If you will consider it an even degree, the graph's shape must be either up, up or down, down. But the graph shows down, up which indicstes its an odd degree. Hope you understand.

Jason eats 10 ounces of candy in 5 days. a. How many pounds does he eat per day?
b. How long will it take Jason to eat 1 pound of candy?
Answers
B. It would take him a total of 8 days to eat a pound of candy.
A. Since he ate 10 ounces in 5 days, you divide 10 by 5 to find he ate 2 ounces per day. Since there are 16 ounces in a pound that would be your denominator (bottom of fraction) and 2 would be the numerator (top of your fraction). You will get 2/16 which if you simplify (divide by 2) you get 1/8.
B. Knowing that there are 16 ounces per pound and he ate 1/8 pound ( 2/16 pound or 2 ounces) a day, you can either look at the simplified denominator to get the answer, or, divide 16 by 2 to get your answer.

In parallelogram DEFG, DH = x + 5, HF = 2y, GH = 3x – 1, and HE = 5y + 4. Find the values of x and y.
Answers
DH = HF and GH = HE
x + 5 = 2y
3x - 1 = 5y + 4
Solve the first equation for x.
x = 2y - 5
Now substitute 2y - 5 for x in the second equation.
3(2y - 5) - 1 = 5y + 4
6y - 15 - 1 = 5y + 4
6y - 16 = 5y + 4
y = 20
Now substitute 20 for y in the first original equation.
x + 5 = 2y
x + 5 = 2(20)
x + 5 = 40
x = 35
Answer: x = 35 and y = 20
The values of x and y in parallelogram DEFG are:
x = 35y = 20Given:
DH = HF and GH = HE
We have the following equations according to the given condition.
x + 5 = 2y ...(1)
3x - 1 = 5y + 4 ...(2)
From equation (1), we can express x in terms of y:
x = 2y - 5 ...(3)
Substitute this value of x in equation (2):
3(2y - 5) - 1 = 5y + 4
Simplify and solve for y:
6y - 15 - 1 = 5y + 4
6y - 16 = 5y + 4
y = 20
Now substitute y = 20 in equation (3) to find x:
x = 2(20) - 5
x = 40 - 5
x = 35
Therefore, the values of x and y in parallelogram DEFG are:
x = 35
y = 20

Write the equation for a parabola that has x− intercepts (−1.6,0) and (−3.2,0) and y−intercept (0,25.6).
Answers
(x-x1)(x-x2)=(x+1.6)(x+3.2)=x² +1.6x+3.2x+5.12=x²+4.8x+5.12
y=x²+4.8x+5.12, but the y-int. is (0, 25.6),
So, our parabola should look like
y=5(x²+4.8x+5.12)
y=5x²+24x+25.6
∞∞∞∞∞∞∞∞
Explanation:
∞∞∞∞∞∞∞∞
x-intercept = (-1.6, 0) and (-3.2, 0)
=====> y = a(x + 1.6)(x + 3.2)
Given y-intercept = (0, 25.6)
=====> 25.6 = a( 0 + 1.6)(0 + 3.2)
=====> 25.6 = 5.12a
=====> a = 5
Plug in a = 5 into the equation
=====> y = 5(x + 1.6)(x + 3.2)

THE FIRST ANSWER GETS BRAINIEST The total height of the Statue of Liberty and its pedestal is 153 feet more than the height of the statue. Write and solve an equation to find the height h (in feet) of the statue.
WRITE THE EQUATION !!
Answers
The complete question is :
The total height of the Statue of Liberty and its pedestal is 305 feet. This is 153 more than the height of the statue. Write and solve an equation to find the height h (in feet) of the statue.
Question says 153, so we add 153 with the height of the statue
The total height of the Statue of Liberty = Height of the statue + 153
305 = h + 153
To find out h we subtract 153 on both sides
305 - 153 = h + 153 - 153
h = 152
The height of the statue = 152 ft
The height of the statue is 152 feet.
Let's call the height of the statue "h" in feet. According to the problem, the total height of the Statue of Liberty and its pedestal is 305 feet, and this is 153 more than the height of the statue. So, you can write the equation as:
Total Height = Statue Height + Pedestal Height
305 feet = h + 153 feet
Now, to find the height "h" of the statue, you can isolate it on one side of the equation. To do that, subtract 153 feet from both sides of the equation:
305 feet - 153 feet = h
152 feet = h
So, the height of the statue is 152 feet.

A total of 327 tickets were sold for the school play. they were either adult tickets or student tickets. the number of student tickets sold was two times the number of adult tickets sold. how many adult tickets were sold?
Answers
109 Adults
Let x = adults
Let 2x = students
Add together and set equal to the total number.
109 adult tickets were sold for the school play.
Explanation:Let's assume the number of adult tickets sold is x.
According to the given information, the number of student tickets sold is 2 times the number of adult tickets sold. So, the number of student tickets sold is 2x.
Since the total number of tickets sold is 327, we can write the equation x + 2x = 327. Simplifying this equation gives us 3x = 327. Dividing both sides by 3, we get x = 109.
Therefore, 109 adult tickets were sold.

What is the length of a garden hose that is stretched diagonally corner-to-corner across a yard that measures 72 meters long and 60 meters wide? Round to the nearest meter.
Answers
length = sqrt (72^2 + 60^2)
= 94 meters to nearest meter
Here, we need to find the length of the hose which is diagonally placed in the rectangular garden.
The length is given as = 72 meters
The width is given as = 60 meters
We will use Pythagoras theorem here.
Hypotenuse² = Perpendicular² + Base²
Hypotenuse² = 72² + 60²
Hypotenuse² = √8,784 meters²
Hypotenuse = 93.72 meters
Thus, the length of diagonal hose will be = 93.72 meters
