Can someone help me find the slope
Answer:
Slope is -2
Step-by-step explanation:
( -3, 7) and ( -2, 5)
Slope:
m=(y2-y1)/(x2-x1)
m=(5-7)/(-2+3)
m = (-2)/1
m = -2
Find the constant of proportionality.
Use the constant of proportionality to write a unit rate for the data in the table.
Write an equation to represent the relationship between time, t, and distance, d. i will give brainliest if u help
Answer:
see explanation
Step-by-step explanation:
(a)
constant of proportion = [tex]\frac{d}{t}[/tex] ( d is distance, t is time )
Use any ordered pair from the table
Using d = 225 and t = 5 , then
constant = [tex]\frac{225}{5}[/tex] = 45
(b)
Unit rate is then 45 miles per hour
(c)
The equation relating the quantities is
d = 45t
Answer:
(a)
constant of proportion = ( d is distance, t is time )
Use any ordered pair from the table
Using d = 225 and t = 5 , then
constant = = 45
(b)
Unit rate is then 45 miles per hour
(c)
The equation relating the quantities is
d = 45t

The Miller family is traveling on a family vacation. They stop at rest stop A along the way. The map, shown below, has a scale of 1 inch to 38 miles.
The Miller family plans to stop at rest stop B next. What is the actual distance, in miles, between the two rest stops?
16.90
40.25
76.25
85.50
Answer:
85.5 miles
Step-by-step explanation:
From the attached diagram, distance between the two rest stops :
Rest stop A to Rest stop B = 2 1/4 inches
Scale factor :
1 in = 38 miles
Acrual distance would be :
2 1/4 inches would be :
2 1/4 * 38 miles
9/4 * 38 = 85.5 miles

The answer is D) $60
Nance I need help hihihihihihihi
Answer:
11 cans
Step-by-step explanation:
1 hr = 60 min
33 hrs = ? min
Setup proportion and solve for x:
[tex]\frac{1hr}{60 min} =\frac{33hrs}{xmin}[/tex]
Do butterfly method and get x = 1980 minutes
Then take the 1980 divide it by 180 to find the number of cans.
[tex]\frac{1980}{180} =11[/tex]

Harry is making cookies. He needs 1 3/4 cups of flour for one batch, but he wants to make 1 1/2 batches. Write an equation that can be used to find how many cups of flour Harry will need.
Answer: 1 3/4 × 1 1/2
Step-by-step explanation:
Since Harry needs 1 3/4 cups of flour for one batch of cookies, but he wants to make 1 1/2 batches, the equation that can be used to find how many cups of flour Harry will need will be:
= (1 3/4 / 1) × 1 1/2
= 1 3/4 × 1 1/2
Therefore, to make 1 1/2 batches, the cups of flour needed will be:
= 1 3/4 × 1 1/2
= 7/4 × 3/2
= 21/8
= 2 5/8 cups of flours.

Answer:
B
Step-by-step explanation:
1200-800+1600+50-105=1945
Answer: B.
The balance starts at $1200. On July 19th, there's an outgoing transfer of $800, so you subtract 800. The remaining balance is 1200-800=$400.
On July 20th, there's an incoming transfer of $1600, so you add that to $400 to get $2000.
On July 23rd, you the account recieves $50 more, so you add that to get $2050.
On July 24th, you have to pay $105, so you subtract that to get $1945.00.
Hope I could help!

Find the area of the parallelogram. Pls explain and I will give brainliest!
Answer:
C: 697 in^2
Step-by-step explanation:
Since parallelograms have parallel lines, the 41 in and 33 in have the same area, the 17 inch and the opposite have the same area too.
You don't need any solution for this since this question already gave you the answer without needing to do any calculation except for finding the area of the parallelogram.
41 x 17 = 697in^2

Find the value of x and tell which triangle it is.
Answer:
x = 23
Obtuse scalane triangle
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
110+35+x+12 = 180
157 + x = 180 subtract x from both sides
x = 23
The given triangle is an obtuse scalane because it has no eqaual side lengths or angles measurment.

devide (a2+ 7a+ 12)÷ (a+3)
Answer:
(a - 3) • (a - 4)
Step-by-step explanation:
The first term is, a2 its coefficient is 1 .
The middle term is, -7a its coefficient is -7 .
The last term, "the constant", is +12
Multiply the coefficient of the first term by the constant 1 • 12 = 12
Find two factors of 12 whose sum equals the coefficient of the middle term, which is -7 .
-12 + -1 = -13
-6 + -2 = -8
-4 + -3 = -7 That's it
Rewrite the polynomial splitting the middle term using the two factors, -4 and -3
a2 - 4a - 3a - 12
Add up the first 2 terms, pulling out like factors :
a • (a-4)
Add up the last 2 terms, pulling out common factors :
3 • (a-4)
Add up the four terms
(a-3) • (a-4)

A fast-food restaurant must apply an 8.5% tax on every sale it makes. How much tax must it charge a customer who purchases a total of $18.50 in food?
Answer: $1.57
Step-by-Step Explanation:
Study.com says: “the formula for calculating the sales tax on a good or service is: selling price x sales tax rate, and when calculating the total cost of a purchase, the formula is: total sale amount = selling price + sales tax,” (study.com, How to Calculate Sales Tax).
So, to find the amount of money they are charging for taxes, we need to use the formula: $18.50 x 8.5%. The selling price is the total sum of the purchase, and the sales tax rate is the percentage number that is apply to every sale as taxes.
Here’s how we solve:
1. To multiply, we first need to change our percentage into a decimal by dividing it by 100. —> 8.5/100 = 0.085
2. Multiply the purchase times the sales tax rate, which is converted into a decimal. —> 18.50 x 0.085 = 1.5725
3. Because money only uses the tenths and the hundredths places, we round up. —> 1.5725 ~ 1.573 ~ 1.57
4. Our answer for the tax amount charged in money is $1.57
Hope this helps!
