Jim bought 20 rose bushes last week. The regular price is $5.00 per bush, but last week they were on sale at 2 for $8.50. How mu
Nikitich [7]

Answer: he saved $15

Step-by-step explanation:

The regular price is $5.00 per rose bush, but last week they were on sale at 2 for $8.50. This means that the amount that one would cost is

8.5/2 = $4.25

If Jim bought 20 rose bushes last week, it means that the amount that he paid for 20 rose bushes is

20 × 4.25 = $85

The regular price is $5.00 per rose bush. If he had bought at the regular price, the amount that he would have paid is

5 × 20 = $100

Therefore, the amount saved by the bushes on sale is

100 - 85 = $15

Marshall drove to work in rush hour traffic, going just 27 miles in 1 hour and 20 minutes. Later that day, he left work early to
iragen [17]

Answer:

The average speed of Marshall is 29.7 mph

Step-by-step explanation:

Given;

distance traveled to work, d₁ = 27 miles

distance traveled back home, d₂ = 27 miles

initial time taken, t₁ = 1 hour and 20 minutes

final time taken, t₂ = 29 minutes

Total distance traveled, d = d₁ + d₂ = 27 miles + 27 miles = 54 miles

Total time taken for the journey, t = t₁ + t₂ = 1 hour + ( 20 mins + 29 mins)

t = 1 hour + 49 mins = 1 hour + 0.817 hour = 1.817 hour

The average speed is given by;

v = total distance / total time

v = 54 miles / 1.817 hour

v = 29.7 mph

Therefore, the average speed of Marshall is 29.7 mph

The width of a rectangle is 3.4 feet. The perimeter is 12.6 feet what is the length
lesya692 [45]

Answer:

the answer is 2.90

Step-by-step explanation:

Picture a rectangle, if one side is 3.4 then the other side 3.4. Add those two togerther gives you 6.8. Now you can subtract 6.8 from the perimeter which is 12.6 then that gives you 5.8. Then you split the 5.8 which give you 2.90 which is the length of the rectangle. So if you label all the sides of the rectangle like this 3.4 + 3.4 + 2.90 + 2.90 = 12.6

Dennis drew the line of best fit on the scatter plot shown below:
matrenka [14]

Answer:

4th option

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (2, 12) and (x₂, y₂ ) = (6, 6) ← 2 points on the line

m = \frac{6-12}{6-2} = \frac{-6}{4} = - \frac{3}{2}

the line crosses the y- axis at (0, 15 ) ⇒ c = 15

y = - \frac{3}{2} x + 15 ← approximate equation of line of best fit
