Answer:

The required ratio is b:c = 9:8

Step-by-step explanation:

We are given:

The ratio a:b = 2:3

and the ratio a:c = 3:4

We need to find the ratio b:c

We are given a:b=2:3

We can write it as: \frac{a}{b}=\frac{2}{3}

Finding value of a: \frac{a}{b}=\frac{2}{3}\\3a=2b\\a=\frac{2b}{3}

Now, we have a:c = 3:4

We can write it as: \frac{a}{c}=\frac{3}{4}

Putting value of a and finding b:c

\frac{a}{c}=\frac{3}{4}\\Put\:a=\frac{2b}{3}\\\frac{2b}{3}}\times \frac{1}{c}=\frac{3}{4} \\Finding\:value\:of\:b/c\\\frac{b}{c}=\frac{3\times 3}{4 \times 2}\\  \frac{b}{c}=\frac{9}{8}

So, we get b/c = 9/8

We can write them in ratio as: b:c = 9:8

Gulf gully and jump rope road are a pretty far distance.If the scale for the map is 0.5 inches=2.3 miles,what is the actual dist
Nezavi [6.7K]

Answer:

12 cm = 21.62 miles

6 cm = 11.04 miles

Step-by-step explanation:

To find the distance, set up a proportion. A proportion is two equal ratios set equal to each other. We form the ratios by using corresponding values. We write a ratio of \frac{map}{real world} and simplify.

We know \frac{map}{real world}=\frac{0.5in}{2.3 miles}. We know the distance on the map is 12 cm and 6 cm whish converts to 4.7 inches and 2.4 inches. We can write \frac{4.7in}{xmiles} and  \frac{2.4in}{xmiles}

We set them equal.

\frac{0.5}{2.3}=\frac{4.7}{x}

and

\frac{0.5}{2.3}=\frac{2.4}{x}

To solve each proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

2.3(4.7)=0.5(x)\\10.81=0.5x\\\frac{10.81}{0.5}=\frac{0.5x}{0.5} \\21.62 miles=x

and

2.3(2.4)=0.5(x)\\5.52=0.5x\\\frac{5.52}{0.5}=\frac{0.5x}{0.5} \\11.04 miles=x

Factor 2pq - 5qr + 10r - 4p.
Tresset [83]
The answer is B) <span>(q - 2)(2p - 5r) 

</span>2pq - 5qr + 10r - 4p = 2pq - 4p - 5qr + 10r
                                 = 2pq - 4p - (5qr - 10r)
                                 = 2p(q - 2) - 5r(q - 2)
                                 = (q - 2)(2p - 5r)

Which of the following formulas would find the surface area of a right cylinder
Sliva [168]

Answer:

A and B

Step-by-step explanation:

Because the surface area is \pi r^2*2\pi rh

BA is the base, so BA + 2\pi rh also works.

HELP PLEASE 50 POINTS!!!! PLZ DON'T GUESS!
Olin [163]

Hey DatGamer13!

Question:

Solve for x

Solution:

Subtract 10 from both sides.

3x^2 + 13x − 10 = 10 − 10

3x^2 + 13x − 10 = 0

Factor left side of equation.

(3x − 2) (x + 5) = 0

Set factors equal to 0.

3x − 2 = 0 or x + 5 = 0

Answer:

x = 2/3 or x = −5
