Answer:

Step-by-step explanation:

It is a 30°-60°-90° triangle.

The lengths of the sides of a 30°-60°-90° triangle are in the ratio 1:√3:2.

The side opposite the 90° angle has length 4, so the side opposite the 30° angle is 2.

x = 2

If the line is perpendicular, that means the slope has to be opposite, so it will have a slope of -1/2

Fill in the point that it has to pass through on y and x

1=-1/2(0) + b

1=0+b

1=b

Then go back to the standard form y=mx + b and fill in the slope and y intercept

Y= -1/2x + 1

What is the answer to adding 3/14 1/7
sp2606 [1]

Hello There!

The answer to adding 3/14 and 1/7 together give you a sum of 5/14

STEP #1 <em>The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.</em>

STEP #2 Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

<h2>(3/14*1/1) + (1/7*2/2)</h2><h2 /><h2><em>3/14 + 2/14 = </em><u><em>5/14</em></u></h2>

Juliette [100K]

Answer:

34 weeks

Step-by-step explanation:

Hello!

We can set up an equation to solve for the number of weeks.

Let w = the number of weeks he is saving up.

The equation is 315 = 115 + 10w - 140

  • 315 is the target amount
  • 115 is the current amount
  • 10w is the rate of growth
  • 140 is the current debt

<h3>Solve for w</h3>
  • 315 = 115 + 10w - 140
  • 315 = -25 + 10w
  • 340 = 10w
  • 340/10 = w
  • 34 = w

He needs to save up for 34 weeks.
