Answer:

F. right angle is correct

Kisachek [45]4 years ago

Answer: The correct choices are D and F.

Step-by-step explanation:

There are two classifications of triangles shown.

Any triangle can only be two.

The first classification depends on the triangles' angles:

  1. Acute triangles are triangles with three angles under 90 degrees.
  2. Right triangles are triangles with a right angle.
  3. Obtuse triangles are triangles with an obtuse angle.

The second classification depends on the triangles' sides:

  1. Equilateral triangles are triangles with three equal side lengths.
  2. Isosceles triangles are triangles with two equal side lengths.
  3. Scalene triangles are triangles with no equal side lengths.

The triangle given has angles of 36, 54, and 90 degrees. 90 degrees is a right angle, so the triangle is a right triangle.

The triangle given has side lengths of 7, 5.1, and 8.66. No side lengths are equal, so the triangle is a scalene triangle.

The correct choices are D and F.

Find the LCM of 15 and 25
Murljashka [212]
The LCM of 15 and 25 is 75

The LCM is the smallest number that you can get from multiplying both numbers.

multiples of 15: 15, 30, 45, 60, 75...
multiples of 25: 25, 50, 75....

as you can see, 75 is the first number to pop up in both.
Hope this helps!  ;D

____ [38]

Answer:

\frac{9}{14} \ chance

Step-by-step explanation:

1. Approach

Probability is a way of predicting a future outcome based on given data. In essence, the formula for finding the probability is, \frac{desired\ outcomes}{total\ outcomes}.

It is given that

- (63) paid with cash

- (22) paid with a debit card

- (13) paid with a credit card

First, add all of these numbers up to find the total number of customers. Then set up the probability, finally, simplify the fraction by diving both the numerator and denominator by a common factor.

2. Find the total number of customers

Add up all of the given customers, regardless of their payment type.;

(cash)+(credit)+(debit)\\\\= 63 + 22 + 13\\\\= 98

(98) total customers.

3. Find the probability

Now set up the probability, remember, the formula for finding the probability is,

\frac{desired\ outcomes}{total\ outcomes}

The desired outcome is the number of customers who pay with cash = (63)

The total outcome is the number of customers who when to the business; (98)

Substitute in the numbers and simplify,

\frac{desired\ outcomes}{total\ outcomes}

\frac{63}{98}

Both of these numbers are divisible by (7), hence divide the fraction by (7)

\frac{9}{14}

The area of a triangular Block is 100 square inches. If the base of the triangle is twice the height,how long are the base and t
timurjin [86]
Area = 1/2 base x height
Area = 1/2 (2 x height) x height
Area = height x height
Area = height^2
100 = height^2
height = SquareRoot(100)
Height = 10
Base = 2 x height = 2 x 10 = 20

Allen runs at an average rate of 9 mi/hr and walks at a average rate of 3 mi/hr. Write an equation in standard form to relate th
den301095 [7]

Answer:

The equation would be 30=12+9x.

Allen will Run for 2 hours.

Step-by-step explanation:

Given:

Total Distance traveled = 30 miles

Average rate of walking = 3 mi/hr

Average rate of running = 9 mi/hr

Time for walking = 4 hours

W need to find the time for running.

Solution:

Let Number of hrs required for running be 'x'.

Total Distance traveled is equal Distance Traveled in walking plus Distance traveled in Running

But Distance is equal Rate multiplied by Time.

Framing in equation form we get;

Hence Total Distance Traveled = Rate of walking × Hours of walking + Rate of Running × Hours of running.

Substituting the values we get;

30 = 3\times4 +9x\\\\30=12+9x

Hence The equation would be 30=12+9x

Solving above equation we get;

9x=30-12\\\\9x=18\\\\x=\frac{18}{9}=2\ hrs

Hence Allen will Run for 2 hours.
