Answer:

337.5 and also 202.5

Step-by-step explanation:

do 8x = 540 since 5 and 3 are in a ratio... so you get 5x plus 3x. Then you solve for x and get 67.5..67.5 times 3 is 202.5 and 67.5 times 5 is 337.5.

<h2> $lets \: number \: to \: be \: 5x \: and \: 3x \\ a.c \: \: \: \: \: (5x) \times (3x) = 540 \\ 15 {x}^{2} = 540 \\ {x}^{2} = \frac{540}{15} \\ {x}^{2} = 36 \\ x = \sqrt{36} \\ x = 6 \\ so \: number \: will \: be \\ 5x = 5 \times 6 = 30 \\ 3x = 3 \times 6 = 18 \\$ </h2><h2>mark it as a Breallent answer </h2><h2>and like❤</h2>

If QT is 9 and TP is 8 Find the length of the following: RP RT RS

anyanavicka [17]

Answer:

i. RP = 17

ii. RT = 15

iii. RS = 30

Step-by-step explanation:

Given that; QT = 9 and TP = 8.

From the diagram, join R to P. Thus RP = QP (radius of the circle)

RP = QT + TP

= 9 + 8

RP = 17

Applying Pythagoras theorem to triangle TRP;

RT = $\sqrt{(RP)^{2} - (TP)^{2} }$

= $\sqrt{17^{2} - 8^{2} }$

= $\sqrt{225}$

= 15

∴ RT = 15

But, RT = TS = 15.

So that;

RS = 15 + 15

= 30

RS = 30

Therefore; RP = 17, RT = 15 and RS = 30.

Answer:

1 7/10

Step-by-step explanation:

First, you would convert the first mixed number into an improper fraction. In this case, it would be 17/4.

The next step would be to multiply the two fractions. To re elaborate, we would be multiplying 17/4 * 2/5. If you don't know how to do that, ask me.

The product is 34/20. It says to simplify the answer into a mixed number, so that would be 1 14/20, simplified to 1 7/10.

Hope this helps! :)
