Answer:

Yes

Step-by-step explanation:

If they're perpendicular, that means that angle ECM = 90 degrees and angle ACE = 90 degrees. To figure out if this works, plug that into the two equations they give:

ECM = 3x + 15

becomes

90 = 3x + 15

75 = 3x

25 = x

ACE = 4x - 10

becomes

90 = 4x - 10

100 = 4x

25 = x

Since you get x = 25 for both, you know that they are perpendicular because they both measure 90 degrees

The quotient of two numbers is 3 and their sum is 8 what are he two numbers
Nezavi [6.7K]
<h2>Translating Word Equations into Numerical Equations</h2>

To change words into equations, we can recognize keywords that translate into operations and/or numbers:

  • <em>quotient</em> = divide
  • <em>a number/the number/two numbers</em> = variables
  • <em>sum</em> = add

<h2>Solving the Question</h2>

Let the two numbers be <em>a</em> and <em>b</em>.

We're given:

  • quotient of <em>a</em> and <em>b</em> is 3
    ⇒ \dfrac{a}{b}=3
  • sum of <em>a</em> and <em>b</em> is 8
    ⇒ a+b=8

First, isolate <em>a</em> in the first equation and substitute it in the second equation to solve for <em>b</em>:

\dfrac{a}{b}=3\\\\a=3b

a+b=8\\3b+b=8\\4b=8\\b=2

Therefore, one of the numbers is 2. Substitute this into one of our equations to solve for <em>a</em>:

a+b=8\\a+2=8\\a=6

Therefore, the other number is 6.

<h2>Answer</h2>

The two numbers are 2 and 6.

It takes 50 oz of grass seed to seed 3000 ft2 of lawn. At this​ rate, how much would be needed for 7200 ft2 of​ lawn?
saw5 [17]

Answer:

120 ounces

Step-by-step explanation:

First find how many ft2 of lawn 1 once can seed.

To do this we simply divide 3000 by 50 ( because 50 ounces of grass seed can seed 3000 ft2 of lawn )

3000 / 50 = 60

So 1 ounce can seed 60ft2 of lawn

To find how many ounces would be needed to seed 7200 ft2 of lawn we would divide 7200 by the amount of lawn 1 once can seed ( which is 60ft2 )

7200/60 = 120

So 120 ounces of grass seed would be needed to seed 7200 ft2 of lawn
