Answer:
9/2 simplified
and 4 1/2 as a mixed number
Answer:
Fraction: 9/2
Mixed: 4 1/2
Step-by-step explanation:
We do this by first finding the greatest common factor of 90 and 20, which is 10.
Then, we divide both 90 and 20 by the greatest common factor to get the following simplified fraction:
9/2
Therefore, this equation is true:
90/20 = 9/2
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction.
9/2 = 4 1/2

Step-by-step explanation:
Jennifer has run many marathons and keeps track of all of her finishing times. At a marathon last month, she finished in 350 minutes. The other day, she ran another marathon and finished with a time of 406 minutes. What is the percent of increase in Jennifer's marathon time?
Answer:
16%
Step-by-step explanation:
406 / 350 = 1.16
406 is 116% of 350
so 350 + 16% is 406
because 350 * 0.16 = 56
56 is 16%
350 + 56 = 406

What is the missing side length of this right triangle? Type the answer in the box.
13 in.
5 in.
х
1
Answer:
12 in
Step-by-step explanation:
Using Pythagoras' theorem in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the missing side , then
x² + 5² = 13²
x² + 25 = 169 ( subtract 25 from both sides )
x² = 144 ( take square root of both sides )
x = [tex]\sqrt{144}[/tex] = 12
Tonya has 5/8 yards of ribbon and is sharing it with Terri by cutting it in half. How much ribbon will each girl have?
Answer:
5/16
Step-by-step explanation:
you can't split 5 in half, so you need to multiply the fraction to make it so you can split it in half. Multiply the equation by 2
5/8 * 2=10/16
now you can divide it by two to get 5/16

What is the rate of change?
Answer: 2 is the correct answer I am 100% positive
Step-by-step explanation:
Answer: the rate of change is 2
Step-by-step explanation:
Complete the following products.
1. (x - y) (x² + xy + y²)
= (__) x² + (__) xy + (__) y²
= __ - x²y + x²y - xy² + __ - y³
= x³ - __
1. (x - y) (x² + xy + y²)
= (X )x² + (X ) xy + (y) y²
= ( x^3)- x²y + x²y - xy² +(xy^2) - y³
= x³ -y^3

Two friends, Bart and Claudia, purchased concessions at a basketball game.
Bart purchased 2 drinks and 2 candy bars for a total of $5.00.
Claudia purchased 1 drink and 4 candy bars for a total of $4.75.
Which statement is true?
Drinks cost $1.75 each, and candy bars cost $0.75 each.
Drinks cost 1 point 7 5 dollars each, and candy bars cost 0 point 7 5 dollars each.
Drinks cost $0.75 each, and candy bars cost $1.75 each.
Drinks cost 0 point 7 5 dollars each, and candy bars cost 1 point 7 5 dollars each.
Drinks cost $1.25 each, and candy bars cost $1.25 each.
Drinks cost 1 point 2 5 dollars each, and candy bars cost 1 point 2 5 dollars each.
Drinks cost $1.00 each, and candy bars cost $0.75 each.
The Drink cost $1.75 each, and candy bars cost $0.75 each.
let
The price of a drink = x
The price of a candy bar = y
Bart total purchase
2x + 2y = 5Claudia total purchase
x + 4y = 4.75The cost of each can be calculated by combining the equations. Therefore,
2x + 2y = 5
x + 4y = 4.75
x = 4.75 - 4y
2(4.75 - 4y) + 2y = 5
9.5 - 8y + 2y = 5
9.5 - 6y = 5
-6y = -4.5
y = -4.5/-6
y = 0.75
2(0.75) + 2x = 5
1.5 + 2x = 5
2x = 5 - 1.5
2x = 3.5
x = 3.5/2
x = 1.75
Cost of a drink = $1.75
Cost of a candy bars = $0.75

Write the equation of the parabola in vertex form.

f(x) =
(Simplify your answer.)
Answer:
Equation of the parabola: y = 3 - 7x^2
Step-by-step explanation:
The equation of the parabola with vertex (h,k) is y = a(x - h)^2 + k
Thus, the equation of this parabola is y = ax^2+3
To find a, use the fact that the parabola passes through the point (1,−4):
-4 = a(1)^2 +3
Solving this equation, we get that a = −7.
Thus, the equation of the parabola is y = 3 − 7x^2.

A chemist mixes 100 milliliters of a solution that is 75% acid with 25 milliliters of a solution that is 35% acid.
Answer the questions below. Do not do any rounding.
(a) How many milliliters of acid are in the resulting mixture?
(b) What percentage of the resulting mixture is acid?
Answer:
85% acid
Step-by-step explanation:
The amount of acid is 83.75 milliliters
The percentage of the resulting mixture of acid is 67%
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
A chemist mixes 100 milliliters of a solution that is 75% acid with 25 milliliters of a solution that is 35% acid.
This means,
75% of 100 milliliters = 75/100 x 100 = 75 milliliters
35% of 25 milliliters = 35/100 x 25 = 8.75 milliliters
Now,
The amount of acid is (75 + 8.75) = 83.75 milliliters
The percentage of the resulting mixture of acid.
= 83.75 / (100 + 25) x 100
= 83.75/125 x 100
= 67%
Thus,
The amount of acid is 83.75 milliliters
The percentage of the resulting mixture of acid is 67%

Denzel identified (3,2) as a point on the line y-2 = 2/3 (x+ 3). What is the error Denzel made?
Hi there!
»»————- ★ ————-««
I believe your answer is:
He identified the incorrect x-value.
See explanation below.
»»————- ★ ————-««
Here’s why:
⸻⸻⸻⸻
[tex]\text{General Point-Slope Form is:}\\\\y - y_1 = m(x-x_1)\\\rule{150}{0.5}\\\\(x_1,y_1) -\text{A point that is given.}\\\\m -\text{Slope}[/tex]
⸻⸻⸻⸻
Denzel incorrectly identified the x-value of the given point. The value '-3' is actually indicated in the equation. If you plug in '-3' into the equation, you would get '-(-3)', which simplifies to '+3'.⸻⸻⸻⸻
[tex]y-2 = \frac{2}{3} (x-x_1)\rightarrow y-2 = \frac{2}{3} (x-(-3))\rightarrow y-2=\frac{2}{3} (x+3)[/tex]
⸻⸻⸻⸻
The point in the equation should be: (-3, 2).
»»————- ★ ————-««
Hope this helps you. I apologize if it’s incorrect.
The correct points of the line will be (-3,2).
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the point (3,2) is on the line y-2 = 2/3(x+ 3). Satisfy the equation with the given point and check.
y-2 = 2/3(x+ 3)
2-2 = (2/3)(3 + 3)
0 = 4
To make left hand side and right hand side equal the value of x coordinate should be -3.
y-2 = 2/3(x+ 3)
2-2 = (2/3)(3 + 3)
0 = 0
Therefore, the correct points of the line will be (-3,2).
