Answer:

<h2>3 ounces</h2>

Step-by-step explanation:

Step one:

given data

the initial amount of chemical = 1.25 ounces

Extra amount of chemical =2.5 ounces

Total amount of chemical =1.25+2.5=3.75 ounces

Step two:

we are told that the scientist used 0.75 ounces of chemical

Hence the remaining chemical is

remaining= 3.75-0.75

remaining= 3 ounces

<u>The remainder is 3 ounces</u>

If you cut a 35 inch long stick in two pieces in the ratio 2:3, how long would each part be?
Aliun [14]

Answer:

14 : 21

Step-by-step explanation:

---> 2:3 ----> 2+3=5

---> Stick's length = 35 inches

<u />

<u>For the first portion</u>

2/5 x 35

2/1 x 7

= 14 inches

<u>For the second portion</u>

3/5 x 35

3/1 x 7

= 21 inches

To confirm: 14 + 21 = 35 inches

14 : 21

Divide both by 7

2 : 3

Can someone please answer this question answer it correctly and show work please

Answer:

$1,216

Step-by-step explanation:

Costs for Handsome Homes fabric

Area (sq. ft.)   Cost (dollars)

        (x)                  (y)

       250               475

       500               950

       750               1,420

       1000             1,900

If you divide any y-value by its corresponding x-value, the quotient will be 1.9

This means that each square foot costs $1.90 at Handsome Homes

Discount Diggers = 20% per sq. ft. less than Handsome homes

Discount Diggers = $1.90 - 20%

Discount Diggers = $1.90(100 - 20%)

Discount Diggers = $1.90(0.8)

Discount Diggers = $1.52

Now that it is known how much 1 square foot of fabric costs at Discount Diggers, we need to find how much 800 square feet of fabric costs.

$1.52 = 1 sq. ft.

$1.52(800) = 800 sq. ft.

$1,216

800 square feet of landscape fabric at Discount Diggers costs $1,216

Hope this helps :)
