Sean wants to make a frame for a painting. The painting is square and has area 196 square inches. The framing material costs ​$1.05 per inch. How much will he ​spend? You may assume that the framing material buys will be the exact amount needs.

Answers

Answer:

$58.80

Step-by-step explanation:

Area = Length * Width              square frame length & width will be the same

√196 = 14 inches                      

  196 = 14 * 14

   196 = 196

14 inches * 4 sides = 56 inches total needed for frame

Cost:

  56 inches * $1.05 = $58.80

Solve for x:
(-3/2)x - 9 = -27

Select one:
a. −24
b. −12
c. 11
d. 12

Answers

This is what the equation looks like: [tex]\frac{-3}{2}x - 9 = -27[/tex]

First, we transpose the terms to the other side. So after transposing [tex]-9[/tex], you get: [tex]\frac{-3}{2}x = -27 + 9[/tex]

Add them and you get: [tex]\frac{-3}{2}x = -18[/tex]

Next we transpose the coefficient of [tex]x[/tex] which is [tex]\frac{-3}{2}[/tex] to the other side, and while doing so the operation changes to a division. When dividing rational numbers, you take the reciprocal so you get: [tex]x = -18 * \frac{-2}{3}[/tex]

Multiply them and you get: [tex]x = 12[/tex]

Therefore, Option D is the correct answer :D

What is the multiplicative rate of change of the function?

1/3
2/3

Answers

Answer:

it is 2/3.

Step-by-step explanation:

please mark as brainliest .

2/3

As x increases by 1
Y decreases by a rate of 2/3.
6x2/3=4
4x2/3=8/3
And so on
To find 2/3, all you need to do is find how y is changing.
First of all, we know that y is decreasing as x increases so the rate is less than 1.
Take y2/y1 to get m or the rate
Ex. 4/6=2/3 which is less than 1!

Carla and George each went hiking.The expressions 4(ℎ + 2) – 2ℎ and 3(2 + ℎ) represent the respective distances Carla and George hiked each day. On what day number h will their distance hiking be the same?
plz help

Answers

Answer:

day 2

Step-by-step explanation:

4(h+2)-2 is 2h+8 and 3(2+h) is 3h+6, and if you do guess and check, when you fill h in as 2, both expressions equal 12.

On the 2nd day, their distance hiking is the same.

Given

Carla and George each went hiking.

The expressions [tex]4(h + 2) - 2h[/tex] and 3(2 + h) represent the respective distances Carla and George hiked each day.

Therefore,

On what day number h will their distance hiking be the same?

[tex]\rm 4(h+2)-2h = 3(2+h)\\\\4h+8-2h=6+3h\\\\2h+8=6+3h\\\\3h-2h=8-6\\\\h = 2[/tex]

Substitute the value of h in the equation first;

[tex]= 4(h+2)-2h\\\\= 4(2+2)-2\times 2\\\\=4(4)-4\\\\=16-4\\\\=12[/tex]

Substitute the value of h in the equation second

[tex]\rm =3(2+h)\\\\= 3(2+2)\\\\= 3\times 4\\\\= 12[/tex]

Hence, on the 2nd day, their distance hiking is the same.

Mei has 60 milliliters of a solution that is​ 35% nitric acid. How many milliliters of nitric acid does the solution​ contain?
(answer this and show your work please)
The solution contains _answer here_ milliliters of nitric acid.

Answers

Answer:

21ml

Step-by-step explanation:

60ml. 35% acid. What is 35% of 60 ml?

÷10 to find 10%

60÷10=6

6=10%

But this is no use

because you cannot multiply 10%to get 35%

(35% is not a multiple of 10)

So we try...

10%÷2=5%

So ÷2 to find 5%

6÷2=3

So 3=5%

5%x7=35%

So, we do

3x7=21

So 35%=21

21ml
