A rectangle has a perimeter of 80 feet. Its height is 5 feet shorter than 4 times its base. What are thedimensions (both base and height) of this rectangle?

Answers

Answer 1
Answer:

Answer:

Let the height be x feet and the base be y feet

1st equation:

2(x+y)=80

x+y=40

2nd equation:

x=4y-5

x-4y=-5

Solution of the 1st and the 2nd equation:

x+y=40.1

x-4y=-5.-1

_________

x+y=40

-x+4y=5

_________

5y=45

y=9

x+y=40

x+9=40

x=40-9

x=31

.

. . The height is 31 feet and the base is 9 feet

Is 7 weeks less or greater than 52 days

Answers

Hey there! :) So 7 weeks = 49 days, right? In order to get 49, you do 7(weeks) x 7(days per week) and get 49. Now, we compare. 49 < 52. 52 is greater.

Step-by-step explanation:

Divide 7/24 by 35/48 and reduce the quotient to the lowest fraction

Answers

(7)/(24) ÷ (35)/(48)
Multiply (7)/(24) by the reciprocal of (35)/(48), which is (48)/(35)

=(7)/(24) × (48)/(35)
=(336)/(840)

We can simplify it further:
The greatest common factor here is 168
(336/168)/(840/168)

=(2)/(5)

Find the distance between points m(-4,6) and n(10,-5). round to the nearest tenth if necessary.

Answers

Use distance formula; d = √((x_1-x_2)^2 + (y_1 - y_2)^2)

You have x_1 = -4, x_2 = 10, y_1 = 6, and lastly y_2 = -5

Plug in these values;

d = √((-4-10)^2 + (6 - (-5))^2)
d = √((-14)^2 + (6 +5))^2)
d = √(14^2 + 11^2)
d = √(317)
d=17.8044938\ldots
d \approx \boxed{17.8}
