Answer:

1.2

Step-by-step explanation:

1. First, we have to write an equation with a variable! Given 0.8%, we know that it's equal to (0.8/100), and "of" means to multiply. Therefore, the equation will looks like this: \frac{0.8}{100} * 150 = x

2. Now, let's solve for x!

  • \frac{0.8}{100} * 150 = (0.008)(150)
  • (0.008)(150) = \frac{6}{5}
  • \frac{6}{5} = 1\frac{1}{5}
  • 1\frac{1}{5} = 1.2
  • 1.2

Therefore, 0.8% of 150 is 1.2!

7 is one tenth of what number
Sloan [31]

<u><em>Answer:</em></u>

70


<u><em>Explanation:</em></u>

Assume that the number we are looking for is x

one tenth is interpreted into \frac{1}{10}


Now, we know that one tenth of the number is 7, this means that:

\frac{1}{10} * x = 7


Solve for x by multiplying both sides of the equation by 10, we get:

\frac{1}{10} * x * 10 = 7 * 10

x = 70


Hope this helps :)

Anyone able to help with this question?
ELEN [110]

Answer:

This is trigonomentry

Use SOHCAHTOA

where :

s is sin

c is cos

t is tan

o is opposite (side)

h is hypotenuse (opposite of 90 degree angle)

and a is adjacent (side)

Sin = o/h

cos = a/h

tan = o/a

in this case we are looking for side BC which is the hypotenuse(h)

and we have the side adjacent(a) to angle 71

since we have a and h determine what to use SIN, COS, OR TAN?

we should use Cos

they‘ve given the angle so we should do this...

Cos71 = \frac{6.3}{h}

Cos71 = \frac{6.3}{BC}

now apply algebra...

6.3/cos71= BC

BC= 19.3507869666

BC = 19.4   (3SF)
