8 0

One way to solve this is to first divide 120 by 10 and get 12 then multiply by 8 and get 96.

Another way to solve this is to turn the percentage into a decimal. divide 80 by a hundred and we get 0.80. Then we multiple 120 by 0.80 and we get 96.

Answer:

y = 15

Step-by-step explanation:

angle poq + angle qor equals mpor (120)

4y + 3y + 15= 120

7y+15=120

subtract 15 from both sides

7y=150

divide both sides by 7

y=15

check:

4(15) + 3(15) + 15 equals 120

60 + 45 + 15 = 120

120 = 120

but a way to work these problems out is to use PEMDAS

p-parentheses

e-exponent

What is the answer of a ?

Scorpion4ik [409]

Answer:

Step-by-step explanation:

Use the cosine law (look at the picture).

We have:

$a=a\\b=4\\c=3\\\gamma=32^o$

$a^2=4^2+3^2-2(4)(3)\cos32^o$

$\cos32^o\approx0.848$ → look at the second picture

$a^2=16+9-24(0.848)\\\\a^2=25-20.352\\\\a^2=4.648\to a=\sqrt{4.648}\\\\a\approx2.2$

What is the slope of a perpendicular line 2x + y = 6<br><br> is answer -2

Firdavs [7]

Answer:

The slope that is perpendicular to the line will be:

$m_2=+\frac{1}{2}$

Step-by-step explanation:

Given the equation

$2x\:+\:y\:=\:6\:$

We know that

$y=mx+b$ is the slope-intercept form of a line where m is the slope and b is the y-intercept.

So, writing the equation in the slope-intercept form

$2x\:+\:y\:=\:6\:$

$\:y=-2x+6$

here

$m=-2$ ∵ $y=mx+b$

As we know that for perpendicular lines, one slope is the negative reciprocal of the other.

Therefore, the slope that is perpendicular to the line will be:

$m_2=+\frac{1}{2}$
