the distance between -2 and 0 is 2 units

the distance between 0 and 3 is 3 units

2+3 = 5

3- (-2) =

3+2 = 5

5 units

If you draw the line and mark -2 and 3 you find that they are 5 apart. By calculation, subtract the lowest from the highest: 3 - -2 = 3+2 = 5

Solve 9-3(x+4)=2(x-3)-8<br> A)3<br> B)2.5<br> C)-2.5<br> D)-4

cupoosta [38]

Answer:

x=11/5, or x=2.2.

Step-by-step explanation:

9-3(x+4)=2(x-3)-8

9-3x-12=2x-6-8

9-12-3x=2x-14

-3-3x=2x-14

-3-3x-2x=-14

-3-5x=-14

5x=-3-(-14)

5x=-3+14

5x=11

x=11/5

x=2.2

Help mee A scout troop are hiking in a forest. Starting from their base, they walk 4.2km south followed by 7.1km west. They want

slega [8]

Answer:

They should walk on a bearing of 59.4 degrees

Step-by-step explanation:

Given

$South = 4.2km$

$West = 7.1km$

Required

The bearing back to the base

The given question is illustrated with the attached image.

To do this, we simply calculate the measure of angle a using:

$\tan(a) = \frac{Opposite}{Adjacent}$

$\tan(a) = \frac{7.1}{4,2}$

$\tan(a) = 1.6905$

Take arctan of both sides

$a = \tan^{-1}(1.6905)$

$a = 59.4^o$

How does 0.008 compare to 0.08

Aleonysh [2.5K]

0.008 would equal to 8/1000 while 0.08 would be 8/10. That would mean 0.008 is much smaller than 8/10. You use the idea of base 10.

Wasn’t sure how to write this out : - )

amid [387]

we are given

$\frac{\sqrt[3]{7}\sqrt{7}}{\sqrt[6]{7^5}}$

we can write it in terms of exponents

$\frac{7^{\frac{1}{3}}*7^{\frac{1}{2}}}{7^{\frac{5}{6}}}$

Firstly , we will simplify numerator

$\frac{7^{\frac{1}{3}+\frac{1}{2}}}{7^{\frac{5}{6}}}$

now, we can add exponents

$\frac{7^{\frac{5}{6}}}{7^{\frac{5}{6}}}$

we can cancel it

and we get

$=1$ ............Answer
