The sum of three consecutive even integers is less than 400.

Answers

Answer:

See below

Step-by-step explanation:

Let the even integers be:

2n, 2n + 2 and 2n + 4

Then we have inequality:

2n + 2n + 2 + 2n + 4 < 4006n + 6 < 4006n < 394n < 394/6n < 65

The numbers are therefore less than 130, 132, 134

The amount of oil used in four different recipes is shown in the table. Recipe Oil Bread 2/8 cup Cookies 1/3 cup Cake 1/5 cup Pie 1/7 cup Which recipe uses the most oil? bread cookies cake pie

Answers

Answer:

cookie

Step-by-step explanation:

Answer: I think that the answer is cookies.

Step-by-step explanation:

The least common denominator for the fractions would be 840.

Bread: 2/8 x 105/105 = 210/840

Pie: 1/7 x 120/120 = 120/840

Cookies: 1/3 x 280/280 = 280/840

Cake: 1/5 x 168/168 = 168/840

Least to greatest:

120/840, 168/840, 210/840, 280/840

That is how I know that the cookies use the most oil.

hi

you must find f°g  

so apply g then f.

g(x) =  2x²+2x-7

f(x) =  2x-7

so  f(gx) =    2  ( 2x²+2x-7) - 7

                 =   4x²+4x-14-7

What is 3/4 of 4/5. Plz help

Answers

Answer:

3/5

Step-by-step explanation:

We want to find 3/4 of 4/5.

The keyword of tells us that we need to multiply. Therefore:

[tex]\frac{3}{4}\times\frac{4}{5}[/tex]

Multiply:

[tex]=12/20=3/5[/tex]

So, 3/4 of 4/5 is 3/5.

We can confirm this by converting them to decimals.

4/5 is 0.8.

3/4 is 0.75.

0.75 or 75% of 0.8 is indeed 3/5 or 0.6.
