Gosh I hope you didn't have to turn this in yet. I'll help you with 4 and 5.

If you want to find the unit rate, you're finding out how much money it is per ounce.
Divide your cost by the number of ounces.

So for example, 3.98 / 16.

After you get your answers, write them down. Whichever answer is the lower number is the better buy because each ounce costs less.

if the area of a square is 144 feet and the perimeter of the triangle is 28 feet, what is the perimeter of the room's floor?

FinnZ [79.3K]

Answer:

$52+12\pi$

Step-by-step explanation:

The diagram for the question is attached below

perimeter of the triangle is 28 feet

area of a square is 144 feet

Area of the square is side^2

$side ^2= 144$

take square root on both sides

side = 12

side of the square = 12

side is the diameter of the semicircle

Diameter = 12 , so radius = 12 divide 2 = 6

circumference of semicircle = $2\pi r=2\pi (6)=12\pi$

one side of the rectangle is calculated in the perimeter of triangle and other side is calculated using circumference

perimeter of other two side = 2(12)= 24

Total perimeter = $28+24+12\pi =52+12\pi$

Answer:

Step-by-step explanation:

Maneesha: 75 % × 37 sunflower seeds equals to 27.75

27.75 is a decimal so rounded off they become 28

her friend: 1/3 × 21 = 7 pumpkin seeds

the total of the seeds will be 28 + 7 = 35 seeds

 

 N:B if you're using decimal calculations. The total amount of seeds will be 34.75

9/(x - 8) = 4/5 how to solve this proportion

ICE Princess25 [194]

$\frac{9}{x-8}=\frac{4}{5}$
Cross multiply:
$(9)(5)=(4)(x-8)$
Simplify:
$45=4x-32$
Group like terms:
$77=4x$
Solve for x by division:
$x=\frac{77}{4}$
$x=19.25$
