The test scores you end up having in geometry class are 81 and 87. What possible scores can you earn on your next test to have a test average between 84 and 89?
Answer:
88, 89, 90, 91, 92? idrk
Answer:
A score between 84 and 99
Step-by-step explanation:
First, let's solve for what you would need to score on your next test to have an average of 84:
(81 + 87 + x)/3 = 84
(168 + x)/3 = 84
168 + x = 252
x = 84
Next, let's solve for what you would need to score on your next test to have an average of 89:
(81 + 87 + x)/3 = 89
(168 + x)/3 = 89
168 + x = 267
x = 99
That means you would have to earn a score between 84 and 99.
I hope this helped you, and if it did, a brainliest would be appreciated :)

7y + 8y can be simplified to 15y?
A. True
B. False
Answer:
A. True
Step-by-step explanation:
Since both 8y and 7y have the same variable, and they are both multiplying with the variable, 8y and 7y can be combined.
If one of the numbers had a different variable or if they were being divided instead then you would not be able to simplify.

Jin adds 1 gallon of a water-and-bleach mixture that is 4% bleach to 2 gallons of a
water-and-bleach mixture that is 10% bleach. What percent of the final mixture is bleach?
Answer:
14%
Step-by-step explanation:
1 gallon + 2 gallons = 3 gallons
1/3 of this is 4% bleach, while 2/3 is 10% bleach, together 3/3 is 14% bleach.

What is the unit rate?
y=5x
Answer:
In the equation y=5x the slope (m) is 5, and the y-intercept is the point (0,0) since there is nothing added or subtracted to the 5x, and thus b = 0.
Step-by-step explanation:
Answer:
measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units. ... When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour,
write an equation in point slope form of the line that passes through the (0,1) and has a slope of -3/2
Answer:
y - 1 = -3/2(x - 0)
Step-by-step explanation:
trust me
The equation of the line in point-slope form is y - 1 = -3/2(x - 0).
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 line that passes through the (0,1) and has a slope of -3/2. The equation of the line will be written as,
y - y₁ = m(x-x₁)
y - 1 = (-3 / 2) ( x - 0 )
Therefore, the equation of the line in point-slope form is y - 1 = -3/2(x - 0).

How will I graph this? It’s due soon please help.
Graph the line with slope 1/2 passing through the point (-2,5).
Answer:
y=1/2x + 6
Step-by-step explanation:
Use point slope form
y-y1=m(x-x1)
y-5= 1/2 (x+2)
y-5= 1/2x + 1
y= 1/2x + 6
Given the speeds of each runner below, determine who runs the fastest. \text{Brooke runs 13 feet per second.} Brooke runs 13 feet per second. \text{Will runs 308 feet in 26 seconds.} Will runs 308 feet in 26 seconds. \text{Ron runs 1 mile in 551 seconds.} Ron runs 1 mile in 551 seconds. \text{Debbie runs 658 feet in 1 minute.} Debbie runs 658 feet in 1 minute.
Answer:
Brooke runs the fastest.
Step-by-step explanation:
Brooke runs 13 feet per second.
Therefore, speed of Broke = 13 feet per sec.
Will runs 308 feet in 26 seconds.
Speed of Will = [tex]\frac{\text{Distance}}{\text{Time taken}}[/tex]
= [tex]\frac{308}{26}[/tex]
= 11.85 feet per second
Ron runs 1 mile in 551 seconds.
1 mile = 5280 feet
Speed of Ron = [tex]\frac{5280}{551}[/tex]
= 9.58 feet per second
Debbie runs 658 feet in 1 minute.
1 minute = 60 seconds
Speed of Debbie = [tex]\frac{658}{60}[/tex]
= 10.97 feet per seconds
Here, speed of Brooke is the maximum.
Therefore, Brooke runs the fastest.

Answer:
67 degrees
Step-by-step explanation:
the shape is a tryangle so it will have the same angle measurements, just make sure you look if it has the slash next to the letter or not in the future
Hope this helps girly!!
Answer:
[tex]\angle{C}=54[/tex]
Step-by-step explanation:
Let's first start by establishing that when it comes to a reflection, side lengths and angle measurements remain the same. With that being said, let's identify our angle measurements:
[tex]\angle{A=}\\\angle{B}= 67\\\angle{C}=\\\angle{A'}=59\\\angle{B'}=\\\angle{C'}=\\[/tex]
As mentioned earlier, angle measurements will remain the same, so we can go ahead and identify the values of [tex]\angle{A}[/tex] & [tex]\angle{B'}[/tex]
[tex]\angle{A=59}\\\angle{B}= 67\\\angle{C}=\\\angle{A'}=59\\\angle{B'}=67\\\angle{C'}=\\[/tex]
The sum of the angles in a triangle will always be equal to 180°.
Add the two identified angles of the original figure.
[tex]59+67=126[/tex]
Subtract the sum from 180:
[tex]180-126=54[/tex]
Therefore:
[tex]\angle{C}=54[/tex]
_
Check your work by adding the three identified angle measurements to see if they measure to 180°:
[tex]59+67+54[/tex]
[tex]=180[/tex]

A culture of bacteria has an initial population of 41000 bacteria and doubles every 5 hours. Using the formula P t = P 0 ⋅ 2 t d P t =P 0 ⋅2 d t , where P t P t is the population after t hours, P 0 P 0 is the initial population, t is the time in hours and d is the doubling time, what is the population of bacteria in the culture after 14 hours, to the nearest whole number?
Answer:
Population of bacteria in culture after 14 hours is 285541.
Step-by-step explanation:
We are given with [tex]P_{t} =P_{0}(2)^{\frac{d}{t}}[/tex]
Here initial population is 41000 , t=5 and d=14
Plug in these values into the formula
[tex]P_{14} =41000(2)^{\frac{14}{5} }[/tex]
Simplify
[tex]P_{14}= 41000(2)^{2.8}[/tex]
=41000(6.9644)
=285540.5847...
To the nearest whole number is 285541.
Answer:
285541.
Step-by-step explanation:
P0=41000-The initial population
t=14-Time elapsed
d=5-The doubling time
Pt=P0⋅2^t/d
Pt=41000⋅2^14/5-Plug in
Pt=285540.5848≈285541-(Use parenthesis in the calculator for the exponent)

Luka buys a special pass to a fair for $7 that allows him to go on every ride for $1 each. How many rides will Luka need to ride in order to spend $20?
Answer:
He would have to do 13 rides.
Step-by-step explanation:
If he initially pays $7, which lets him pay only $1 for each ride, so when he spends $20, he would have done 13 rides.
There are 13 rides will Luka need to ride in order to spend $20.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Luka buys a special pass to a fair for $7 that allows him to go on every ride for $1 each.
Here, Luka need to ride in order to spend $20.
Let number of rides = x
So, We can formulate;
⇒ $7 + $1x = $20
⇒ 7 + x = 20
Solve for x as;
⇒ x = 20 - 7
⇒ x = 13
