Answer:

False

Step-by-step explanation:

The definition given is that of an equilateral triangle, NOT that of an isosceles triangle. An isosceles triangle has at least two angles that are equal by definiton. They need not be 60 degrees. For example, a triangle with angle measures of 140, 20, and 20 is an isosceles triangle because two of the angles are equal. Hope this helped!

Answer:

4.25%

Step-by-step explanation:

Step 1: Calculate the commission paid

Commission = Gross earning - base salary

Commission = 441.3 - 375

Commission = 66.3

Step 2: Calculate the commission sales

Commission sales = Total sales - quota sales

Commission sales = 6560 - 5000

Commission sales = 1560

Step 3: Calculate the rate of commission

x% of 1560 = 66.3

x% * 1560 = 66.3

x% = 0.0425

x = 4.25%

Therefore, the rate of commission was 4.25%.

A university is composed of five schools. The enrollment in each school is given:

Lostsunrise [7]

Answer:

34.767 enrollments/computer

Step-by-step explanation:

According to the Hamilton's method, the standard divisor, D, is determined by dividing the number of enrollments in all schools by the number of new computers available:

$D=\frac{1050+1410+1850+2540+3580}{300}\\D=34.767\ enrollments/computer$

The standard divisor for this situation should be 34.767 enrollments/computer.

The base of an isosceles triangle is 9 and its perimeter 49. The base of a similar isosceles triangle is 14. What is the missing

ratelena [41]

Answer: 76.2

Step-by-step explanation:

Perimetar of isiscales triangle is calculated using equation;

P=b+2a

b=9

P=49

lets find sides of triangle.

P-b=2a

a=(P-b)/2

a=49-9/2

a=40/2=20

If another triangle is similar that means that his base and sides are proportional to first triangle.

Base of first trianlge b₁=9

Base of similar triangle is b₂=14

use proportion to find out side of similar triangle:

b₁:b₂=9:14

a₁:a₂=9:14

a₁=20

20: a₂=9:14

a₂=14*20/9=280/9=31.1

Perimetar of second triangle is:

P₂=b₂+2a₂

P₂=14+2*31.1=14+62.2=76.2
