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:

The midpoint is (2,0)

Step-by-step explanation:

To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2

(5+-1)/2 =4/2 =2

To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2

(6+-6)/2 =0/2 =0

The midpoint is (2,0)

2- (25-36) + 5×4

3- (-11) + 20 =9

Answer:

the answer is 1.

Step-by-step explanation:

Try and plug in 1 as in x it would come out with equal to b0th sides

Answer:

x = 1

Answer:

12°

Step-by-step explanation:

The two shaded angles are alternate-interior angles

(Either side of the transversal line, and inside both parallel lines, AB||CD)

10x + 5 = 12x - 19

10x + 24 = 12x

24 = 2x

x = 12

Answer:

hanging the radius by a given amount has a greater effect on the volume than changing the height by the same amount. This is because the value of the radius is squared in the formula.Step-by-step explanation:

Step-by-step explanation:

2a^2+5/7+b

a= -6

b= -2

solution

2(-6 x -6 )+5/7 +-2

2(36)+5/7+( -2 )

2x36=72

so it will be

72+5/7+ (-2)

72+5=77

77/7+(-2)

= 11+(-2)

=9

9 is the answer.

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

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:

Yes this statement is true because 0/3 is 0

Answer:

False.

Step-by-step explanation:

x = 0 would be the only solution to make the statement true. Anything other than x = 0 will make the statement false.

Answer:

1.2 is less so your answer should be 1.2.

= 1.2

If you're measuring mountains, they're both huge.

If you're measuring green peas, they're both small.

Either way, 1.2 is smaller than 1.7 .

Yes

Step-by-step explanation:

[tex] \frac{16}{24} = \frac{2}{3} [/tex]

if we divide 16 ÷ 8 = 2

if we divide 24 ÷ 8 = 3

[tex] \frac{28}{42} = \frac{4}{6} = \frac{2}{ 3} [/tex]

if we divide 28 ÷ 7 = 4

if we divide 42 ÷7 = 6

we divide both 6 and 4 ÷2

2/3

[tex] \frac{16}{24} = \frac{28}{42} [/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:

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]
