Answer:
20%
Step-by-step explanation:
I looked it up haha :)
HOWEVER here is how you actually do it
15:75*100 =
( 15*100):75 =
1500:75 = 20
Have a good day!
Answer:
20%
Step-by-step explanation:
your part and whole have to equal too 100
[tex]\frac{15}{75}[/tex] = [tex]\frac{x}{100}[/tex]
simplify 15 and 75 to 1/5
5x20 = 100
1 x 20 =20

A group of friends were working on a student film with a budget of $700, which they
spent on costumes and equipment. They spent $168 on equipment. What percent did
they spend on costumes?
Answer:
76%
Step-by-step explanation:
First do 700 - 168 which is 532
Next we see that 700 is 100% in this scenario
Then we will use the value we seek as ‘x’
So, x% = 532
We can put the two equations, 100%/x% = 700/532
they both have LHS
We can take the inverse from both sides yields
Therefore, the answer is 76%

Answer:
V ≈ 160 ft³
Step-by-step explanation:
V = [tex]\frac{\pi r^2h}{3}[/tex] ( r is the radius and h the height )
Here the diameter = 8 then r = 8 ÷ 2 = 4 and h = 10 , then using π ≈ 3
V ≈ [tex]\frac{3(4)^2(10)}{3}[/tex] ( cancel 3 on numerator/ denominator )
= 4² × 10
= 16 × 10

In 5-8, write an equation of the trend line in slope-intercept form.
First, find out the y-intercept(s).
For 5, it is 6. For 6, it is 150. For 7, it is 20. For 8, it is 0.
Now we need to find the slopes.
For 5, it goes down one and right 2, so it would be -1/2 (rise/run).
For 6, it goes up 100 and right 2, so it would be 100/2 (rise/run) or 50.
For 7, it goes up 10 and right 3, so it would be 10/3 (rise/run).
For 8, it goes up 25 and right 1, so it would be 25/1 (rise/run) or 25.
Then you plug into the equation: y = mx + b
5: y = -1/2x + 6.
6: y = 50x + 150.
7: y = 10/3 + 20.
8: y = 25x + 0 which would be y = 25x (since add 0 is useless).
Calculate the size of each angle in the triangle.
2x
2x + 5
3x+7
Answer:
48°, 53°, and 79°
Step-by-step explanation:
The sum of angles of a triangle is 180 (degrees), so you have ...
2x +(2x +5) +(3x +7) = 180
7x +12 = 180
7x = 168
x = 24
Then the measures of the angles are ...
2(24) = 48
2(24) +5 = 53
3(24) =7 = 79
The angles are 48°, 53°, and 79°.
A railroad crew can lay 5 miles of track each day. They need to lay 140 miles of track. The length, L (in miles), that is left to lay after d days is given by the
following function.
L(d) = 140-50
Answer the following
(a) How many days will it take the crew to lay all the track?
I days
(b) How many miles of track does the crew have left to lay after 18 days?
miles
Answer:
a) 28 days
b) 50 miles
Explanation:
a) 5 miles a day
140 miles ? days
140÷5= 28 days
b) 5 miles a day
? miles 18 days
18×5= 90 miles
140 miles - 90 miles = 50 miles

) The product of a number and 3 is 7.5. What is the number?
) First, write an equation to describe the situation,
---
+
Answer:
2.5
Step-by-step explanation:
X × 3=7.5
divide by 3
x=2.5
The required equation to describe the situation is x × 3 = 7.5, and the number is 2.5.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The equation to describe the situation is:
x × 3 = 7.5
Where x is the number.
This equation states that the product of a number (x) and 3 is equal to 7.5. This equation can be read as "x multiplied by 3 equals 7.5."
To find the value of x, we can solve for x by dividing both sides of the equation by 3:
x = 7.5/3
x = 2.5
So, the number is 2.5.
You can check this by substituting the value of x back into the equation:
x × 3 = 7.5
2.5 × 3 = 7.5
7.5 = 7.5
So, it holds true.

Atte: ღTheGirlSadღA wall is 300 square feet.a gallon of paint covers 110 square feet. What is an appropriate conversion factor to help determine how many gallons of paint will be needed to paint the wall?
Answer:
(1 gallon)/(100 ft^2)
Step-by-step explanation:
(1 gallon)/(100 ft^2) is a good conversion factor. We could also use (100 ft^2)/(1 gallon), but I like the first, since the calculation is simpler:
(300ft^2)*/(1 gallon)/(100 ft^2) = 3 gallons [I like multiplication better than division, and especially here, since 300/100 is 3, if my memory is correct.

Answer:
x = -0.90, y = 2.31x = 1.40, y = 9.19Step-by-step explanation:
Equating the expressions for y will give a quadratic in x:
4x^2 +x = 3x +5
4x^2 -2x = 5 . . . . . . collect x-terms on the left
4(x^2 -1/2x) = 5 . . . .factor out the leading coefficient
4(x^2 -1/2x +1/16) = 5 4/16 . . . . complete the square
4(x -1/4)^2 = 84/16 . . . . write the quadratic as a square
x -1/4 = (±√21)/4 . . . . . divide by 4 and take the square root
x = (1 ±√21)/4 . . . . . . . add 1/4
y = 3x +5 = 3(1 ±√21)/4 +5 = (23 ±3√21)/4 . . . . use the linear equation for y
The solutions are ...
x = (1 -√21)/4; y = (23 -3√21)/4 ≈ 2.31
x ≈ -0.89, y ≈ 2.31
x = (1 +√21)/4; y = (23 +3√21)/4
x ≈ 1.40, y ≈ 9.19
The diagonals of the parallelogram are equal to 17 and 19, and the sides are proportional to each other as 2:3, Find sides.
Answer:
10 and 15 unitsStep-by-step explanation:
Given:
d₁ = 17d₂ = 19a = 2xb = 3xUse the relationship between diagonals and sides of the parallelogram:
d₁² + d₂² = 2(a² + b²)Substitute and solve for x:
17² + 19² = 2((2x)² + (3x)²)650 = 2(4x² + 9x²)325 = 13x²x² = 325/13x² = 25x = 5Find the sides:

The factored form of the quadratic expression 2x³ + 4x² - x is x(2x² + 4x - 1).
The correct option is D.
What is the greatest common factor?The greatest number can divide the numbers into equal parts.
It is called the greatest common factor.
To factor 2x³ + 4x² - x, we can first factor out the greatest common factor, which is x:
2x³ + 4x² - x = x(2x² + 4x - 1)
Now, we need to factor the quadratic expression 2x² + 4x - 1. We can use the quadratic formula to find its roots:
x = (-b ± √(b² - 4ac)) / 2a
where a = 2, b = 4, and c = -1:
x = (-4 ± √(4² - 4(2)(-1))) / 2(2)
x = (-4 ± √(20)) / 4
x = (-4 ± √(5)) / 4
x = (-2 ± √(5)) / 2
Therefore, the factored form of 2x³ + 4x² - x is:
2x³ + 4x² - x = x(2x - (-2 + √(5)))(2x - (-2 - √(5)))
