Answer:

(3a + b) : (4a +2b) = 5 : 8

Step-by-step explanation:

For:

[tex]a : b = 1 : 2[/tex]

Express these ratios into fractions:

[tex] \frac{a}{b} = \frac{1}{2} [/tex]

Simplify:

[tex]2a = b - - - \{eqn \: (n) \}[/tex]

For:

[tex](3a + b) : (4a +2 b)[/tex]

Express into fractions:

[tex] = \frac{(3a + b)}{(4a + 2b)} \\ [/tex]

substitute for b as 2a from equation (n):

[tex] = \frac{(3a + 2a)}{(4a + 4a)} \\ \\ = \frac{5a}{8a} \\ \\ = \frac{5}{8} [/tex]

express into ratios:

[tex] = 5 : 8[/tex]

Answer:

-4%   -1/25

Step-by-step explanation:

To convert a decimal to a percentage, multiply it by 100.

-0.04 * 100 = -4

To convert a decimal to a fraction, put the decimal as a fraction over 1 and multiply until the numerator (top number) is a whole number and then simplify.

[tex]\frac{-0.04}{1}[/tex] x [tex]\frac{100}{100}[/tex] = [tex]\frac{-4}{100}[/tex]

-4/100 simplified = -1/25 (because 4 goes into 100 25 times)

Answer:

495/224

Step-by-step explanation:

15/32⋅36/28⋅44/12

= (15/32(9/7))(44/12) [simplify 36/28]

=135/224 (44/12) [multiply]

=135/224 (11/3) [simplify 44/12]

=495/224 [cross multiply]

Answer:

It would be 98.12 dollars

Step-by-step explanation:

Hope this helps. :D

The original price of the car stereo before any discounts or taxes was approximately $187.14.

We have,

Gina paid $131 for the car stereo after it was discounted by 30%.

Let's represent the original price of the stereo as "x" dollars.

The discounted price would be 70% (100% - 30%) of the original price:

Discounted price = 0.70 * x

Given that Gina paid $131, we can set up the equation:

0.70 * x = 131

Now, solve for "x" by dividing both sides of the expression by 0.70:

x = 131 / 0.70

x ≈ 187.14

So, the original price of the stereo before the discount was approximately $187.14.

There was also 7% sales tax on the purchase.

To find the sales tax amount, we calculate 7% of the original price:

Sales tax = 0.07 * 187.14 ≈ 13.10

Now, to find the total original cost before the sales tax, we add the original price and the sales tax:

Total original cost = Original price + Sales tax

Total original cost ≈ 187.14 + 13.10 ≈ 200.24

Therefore,

The original price of the car stereo before any discounts or taxes was approximately $187.14.

Answer:

The distance between the pair of points is 12.0 (to the nearest tenth)

Step-by-step explanation:

The distance between a pair of points in a coordinate system is found by the formula:

d =[tex]\sqrt({x_2-x_1)^2+(y_2-y_1)^2}[/tex]

where, the points are:

[tex](x_1,y_1)\ and\ (x_2,y_2)[/tex]

From the graph,

[tex](x_1,y_1)=(-6,-2)\\(x_2,y_2)=(2,7)[/tex]

Substitute the points into the formula:

[tex]d=\sqrt{(2-(-6)^2+(7-(-2)^2} \\d=\sqrt{(2+6)^2+(7+2)^2} \\d=\sqrt{8^2+9^2} \\d=\sqrt{64+81} \\d=\sqrt{145} \\\d=12.0[/tex]

Answer:

a. circumference

b. area

c. area

d. circumference

Step-by-step explanation:

a. You are using the circumference formula to find the distance around a CIRCULAR track, if you used area, that would include the space in between the track as well. You are only trying to find the track line. ( you can draw a picture of a track and show what you are finding. )

b. You are trying to find the amount of area that the tiles make up in the circular floor, how much of the floor the tiles take up.

c. You are trying to find how much of the oil takes up of the WHOLE bottom of the frying pan.

d. Finding the circumference of your wheel can help determine the distance the car traveled. If you used area, it would not be useful.

Answer:

  130°

Step-by-step explanation:

The angle sum theorem applies.

  ∠WXY = ∠WXZ +∠ZXY

  ∠WXY = 110° +20°

  ∠WXY = 130°

Simplifying Rs = st + -1Rt Solving sR = st + -1tR Solving for variable 's'. Move all terms containing s to the left, all other terms to the right. Add '-1st' to each side of the equation. sR + -1st = st + -1st + -1tR Combine like terms: st + -1st = 0 sR + -1st = 0 + -1tR sR + -1st = -1tR Combine like terms: -1tR + tR = 0 sR + -1st + tR = 0

s = − Rt / R − t
