**Answer: ** units.

**Step-by-step explanation:**

The distance between points (a, b) and (c, d) is given by :_

Given points : (-10,-7) (-8,1)

Distance between points (-10,-7) and (-8,1) =

Hence, distance between given points = units.

**Answer:**

Given

if p:q=2/3:3 and p:r=3/4:1/2, calculate the ratio p:q:r giving your answer in its simplest form

We need to find the ratio p:q:r

Given p:q = 2/3 : 3 = 2/3 / 3 = 2/9

and p : r = 3/4 : 1/2 = 3/4 / 1/2 = 3/2

Now p/q = 2/9 and p/r = 3/2

We need to make p equal numerators so we get

p/q = 2/9 x 3/3 = 6/27 and

p/r = 2/3 x 3/2 = 6/4

Therefore p : q : r = 6 : 27 : 4

Answer:

6.99x 10^(7) = 69,900,000

3.61x10^(7) = 36,100,000

8.3x10^(6) = 8,300,000

question 1

114,300,00 is them all added up

1.143x10^(9) is standard form

and i do belive part a's answer is the 6.99x10^(7) and so on and so forth. I hope this helps. X3 i did my best.

**Answer:**

Tia cut a 4-meter 8-centimeter wire into 10 equal pieces. for Jay 10 quarts would be the answer. Step-by-step explanation: He needs x quarts for the inside painting and x + 19 quarts for the outside. These two measures add up to 2x + 19, which equals 107 (quarts) total. The last one is tring A is 35 cm long, string B is 5 times as long as string A, then string B is 35·5=175 cm long. In total both strings have length 35+175=210 cm. The total length of string needed for 17 identical decirative bottes is cm that is 35.7 m.
