Write inequalities to represent the situations below.
The vehicle's fuel efficiency is no less than 45 miles per gallon.
Use f to represent the vehicle's fuel efficiency (in miles per gallon).
Martina exercises at least 45 minutes per day.
Use t to represent Martina's amount of exercise (in minutes per day).
Answer:
[tex]f \ge 45[/tex]
[tex]t \ge 45[/tex]
Step-by-step explanation:
Solving (a): No less than 45
In inequalities, no less than means [tex]\ge[/tex]
So, the statement can be represented as:
[tex]f \ge 45[/tex]
Solving (b): At least 45
In inequalities, at least means [tex]\ge[/tex]
So, the statement can be represented as:
[tex]t \ge 45[/tex]

A golf store purchases a set of clubs at a wholesale price of $250. Mr. Edmond learned that the clubs were marked up 200%. Is it possible to have a percent increase greater than 100%? What is the retail price of the clubs? help plz i only ave 13 points but plz help and i will give you brainly
Answer:
Yes, it is possible to have a percent increase greater than 100%. The retail price of the clubs is $750
Step-by-step explanation:
Because the clubs were marked up 200%, we need to add 200% to 100%.
Then to find the retail price, we have to multiply 300%(3) by the wholesale price of $250.
Retail price = 3(250) =750
Therefore, the retail price is $750

Answer:
I am pretty sure B is correct answer
Answer:
A. Slope is -5. Y-intercept is (0,7)
Step-by-step explanation:
1. Find the slope using the slope formula and the coordinates
Remember, the slope formula is: y2-y1/x2-x1
You'll use the coordinates (0,7) (4, -13) to plug into the formula.
-13-7/4-0
= -20/4
= -5
Slope is -5
2. Find the y-intercept.
First, write the equation of the line in point-slope form: y-y1=m(x-x1)
M is slope and y1 and x1 can be from any ordered pair (as long as they're from the same one). Let's use (0,7)
y-7=-5(x-0)
Simplify the equation.
y-7=-5x+0
y=-5x+7
3. Now the equation is in y-intercept form, or y=mx+b. Again, M is slope. B is the y intercept. So, the y-intercept is 7

The temperature at Wonder Lake is 12 F. During a storm, the temperature changes by -26 F. What is the temperature after the storm? Show your work.
I will give Brainly! Pls help!
Answer:
-14
Step-by-step explanation:
if the temperature is 12 at the beginning and there is a -26 temperature change you subtract 12 by -26
12-(-26) = 14
or
you take 26 and subtract 12
26 - 12= -14
and now you have a temperature of 0 with -14 to go so you get -14
The temperature after the storm is = - 14 F
We have temperature at Wonder Lake which is 12 F and during a storm, the temperature changes by - 26 F.
We have to determine the temperature after the storm.
' The temperature of an area is y degrees below zero '. What does this statement mean ?A temperature of y degrees below zero means that the temperature of an area is equal to = - y degrees i.e., T = 0 - y = - y.
According to question -
Initial Temperature T(i) = 12 F
Let the final temperature T(f) = x
Change in temperature ΔT = T(f) - T(i) = x - 12
- 26 = x - 12
x = - 26 + 12
x = - 14 F
Hence, the temperature after the storm will be = - 14 F

Mikhail believes he can use the multiplication expression 1/2x6 to find the total number of
pound servings of rice he can make
from 6 pounds of rice. Which statement best explains why Mikhail is correct or incorrect?
Mikhail is correct in using a multiplication expression because the product of 6 and 1/2 is an integer.
Mikhail is correct in using a multiplication expression because 1/2 is the number of servings per pound.
Mikhail is incorrect in using a multiplication expression because the term "total" implies finding the sum of an addition
expression.
Mikhail is incorrect in using a multiplication expression because the question asks how many equal-sized parts 6 can be
divided into.

Can a triangle have lengths of 2, 2 and 18?
(pls with a actual explanation bc its open ended <3)
Answer:
No, a triangle cannot have lengths of 2, 2 and 18
Step-by-step explanation:
The sum of 2 sides of a triangle must be greater than the third side.

Adam is in mexico where the temperature is given in degrees Celsius. to convert to Fahrenheit, you multiply the Celsius temperature by 9 over 5 and add 32. which equation can you use to convert Celsius temperatures to Fahrenheit temperatures.
A)f=9 over5c+32 b) f=9over5(c+32) C) f=9over5+32c D) f=c(9over5+32)
Answer:
[tex]F = \frac{9}{5}C + 32[/tex]
Step-by-step explanation:
Given
Represent Celsius by C
Required
Convert Celsius to Fahrenheit
Taking the instruction in the question one after the other:
Multiply C by 9/5
[tex]\frac{9}{5} * C[/tex]
Add 32
[tex]\frac{9}{5} * C + 32[/tex]
Equate to Fahrenheit (F)
[tex]F = \frac{9}{5} * C + 32[/tex]
[tex]F = \frac{9}{5}C + 32[/tex]
Hence, option A is correct
