In the right triangle ABC, CD is an altitude, and c=e+f,by combining three equations it can be shown that a^2+b^2=c^2.One of the equations is c=e+f.which of the following could be the other two equations

Answer:

The two missing angles are 20 and 30 degrees.

Step-by-step explanation:

Quadrilaterals have four interior angles that add up to 360 degrees.

So we have two angles that are 240 degrees and 70 degrees.

If 240 + 70 = 310

That means the other two angles added together must be equal 50.

Because 360 - 310 = 50

So their ratio is 2:3 which means they have five equal parts.

Which would mean 50/5 = 10

2 x 10 = 20

3 x 10 =30

This means the missing angles are 20 and 30 degrees.

I think 247 is your answer!

Step-by-step explanation:

$560 plus a 6.5% of her sales = 596.4 US$

3800 plus a 6.5% of her sales last week = 4047

6.5% of 3800 is 247

Answer:

32%

Answer: 18 ≤ 6*S ≤ 30

Where S is the number of salmon fillets in one single package.

Step-by-step explanation:

Let's define S as the number of salmon fillets in one package.

We know that it contains at least 3, and no more than 5, then we can write:

3 ≤ S ≤ 5

Now we want to know the total number of salmon fillets that could be on 6 packages, then if S is the number of salmon fillets in one package, 6*S will e the number of salmon fillets in 6 packages.

We can find this by multiplying the inequality:

3 ≤ S ≤ 5

by 6.

We get:

6*3 ≤ 6*S ≤ 6*5

18 ≤ 6*S ≤ 30

Then in 6 packages, we could have any number between 18 and 30 fillets of salmon.

Answer:

x = 2√5

Step-by-step explanation:

Using the Pythagorean Theorem:

a² + b² = c²

You can identify that x is the hypotenuse, as it is opposite to the right angle.

So:

3² + √11² = x²

9 + [(√11) (√11)] = x²

9 + 11 = x²

20 = x²

√20 = √x²

√4√5 = x

2√5 = x

x = 2√5

Answer:$12$

Step-by-step explanation:

The amount of speed by which kendri exceeded the speed limit is; 9 mph

We are given;

Distance; d = 18.4 miles

Time; t = 16 minutes = (16/60) hours

Now, the formula for speed is;

Speed = distance/time

Thus, let's Calculate kenji's speed;

Kenji's speed = 18.4/(16/60)

Kenji's speed = 69 mph

We are told that the speed limit is to be 60 mph, this means that kendri exceeded the speed limit by;

69 - 60 = 9 mph

Answer:

14 pieces

Step-by-step explanation:

Given that the total length available is 9 1/3 ft long and the pieces being cut is 2/3 ft long, the number of pieces that may be cut may be computed by dividing the total length by the length of each piece

= 9 1/3 / 2/3

= 28/3 * 3/2

Answer:

We can solve this question using the slope equation which is y2-y1/x2-x1

If you use that formula and sub in the coordinates

-4 - 5 / -1-2
