There is a triangle with sides measuring 301, 30in and 25. Is this a nighttrange? Why or why not?

Answers

Answer 1

Answer:

No

Step-by-step explanation:

Assume you are asking if 30 in, 30 in, 25 in triangle if right.

Since two longer sides are equal this can't be a right triangle. Remember the hypotenuse is the longest side and the right triangle can be isosceles if shorter sides are of same size.

Answer 2

Check through Pythagorean theorem

H²=P²+B²301²=30²+25²

No it's false

It's not right angled

A cylinder has a volume of 200in^3. Determine the volume of a cone whose radius and height are equal to that of the cylinder

Answers

Answer:

66.67 in^3

Step-by-step explanation:

volume of a cylinder = nr^2h

Volume of a cone =  1/3(nr^2h)

n = 22/7

r = radius

the volume of a cone is 1/3 that of a cylinder

volume of the cone = 1/3 x (200) = 66.67 in^3

which expression can he used to find the surface area of the following sqare pyramid​

Answers

Answer:

answer: A

Because when doing area for triangles its

base × height ÷ 2 so for 1 triangle it would be 5 × 4 = 20 then ÷ by 2 so 20 ÷ 2 = 10 Since there are 4 triangles we will have to add 10 4 times and then for the square it's easily just 4 × 4 = 16

so it would come out to 16 + 10 + 10 + 10 + 10 =

Jersey village population in 1950 was 10,173. The population increases by 8.9% every 10 years. Predict the population in 2020

Answers

Answer:

Future Value= 18,478 people

Step-by-step explanation:

eGiving the following information:

Present value (PV)= 10,173

Growth rate (g)= 0.089 every 10 years

Number of periods (n)= 7

To calculate the population in 2020, we need to use the following formula:

FV= PV*(1 + g)^n

FV= 10,173*(1.089^7)

FV= 18,478 people

The equivalent expression for the algebra m(n+p) is mn + mp.

What are equivalent expressions?

Equivalent expressions are similar expressions that when being solved provide the same solution. Equivalent expressions are used widely in the expansion of algebraic equations.

From the given information, we have:

=  m(n + p)

To determine the equivalent expression for the above algebraic equation, we need to expand the bracket as follows:

= m(n) + m(p)

= mn + mp

Answer:

x = 76

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

152° is an exterior angle of the triangle , then

x + x = 152

2x = 152 ( divide both sides by 2 )

x = 76

Answer:

x+x=152° (sum of two opposite interior angles is equal to exterior angle)

2x=152°

x=76 °
