Step-by-step explanation:

Answer:

80

Step-by-step explanation:

Delta math math

The length of m in triangle MNO is approximately 80 inches.

Triangle is defined as a basic polygonal shape of a triangle that has three sides and three interior angles.

In ΔMNO, n = 85 inches, o = 10 inches, and ∠M=56°.

In this case, we are given the lengths of sides n and o and the measure of angle M. We can use the law of cosines to solve for the length of side m:

⇒ m² = n² + o² - 2 × n × o × cos(∠M)

We are given that n = 85 inches, o = 10 inches, and ∠M = 56°. We can use these values to solve for m:

⇒ m² = 85² + 10² - 2 × 85 × 10 × cos (56°)

We can use a calculator or look up the value of cos 56° to find that it is approximately 0.6. Plugging this value into the formula above gives us:

⇒ m = 79.8397 ≈ 80 inches

Therefore, the length of m in triangle MNO is approximately 80 inches to the nearest inch.

Answer:

350

Step-by-step explanation:

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100

120% = 120/100 = 120 ÷ 100 = 1.2

100% = 100/100 = 100 ÷ 100 = 1

Percentage of 120% of what number = 420?

120% × ? = 420

? =

420 ÷ 120% =

420 ÷ (120 ÷ 100) =

(100 × 420) ÷ 120 =

42,000 ÷ 120 =

350

If 120% × 350 = 420 =>

Divide 420 by 350...

... And see if we get as a result: 120%

Multiply a number by the fraction 100/100,

... and its value doesn't change.

100/100 = 100 ÷ 100 = 1

n/100 = n%, any number.

Step-by-step explanation:

Answer:

so angle a is 60 and angle c is 80. you add those together to get 140. you then subtract 140 from 180 and you get 40. lastly you divide 40 by 2 and you get 20 for x.

The point (-3,1) is not passing through the graph y = -2x + 7 so option (C) will be correct.

A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.

In order to plot the graph, we need to find out y's values corresponding to x's value

After that, we need to substitute the values of x's and y's into the coordinate geometry.

Given that a line  y=-2x+7

Now in order to satisfy any point of this function then the value or

coordinate should satisfy the function or line.

So by checking option (A) 9 = -2(-1) + 7 = 9 so its satisfy.

So all options except (C) are satisfying.

Option (C) ⇒

-2(-3) + 7  ≠ 1

Hence "The point (-3,1) is not passing through the graph y = -2x + 7".
