What is a area of a triangle with a heigt of 5 inches and a base of 10inches
nydimaria [60]

Answer: 25 in²

Step-by-step explanation: To find the area of a triangle, start with the formula for the area of a triangle which is shown below.

Area = \frac{1}{2} bh

In this problem, we're given that the base is 10 inches

and the height is 5 inches.

Now, plugging into the formula, we have (\frac{1}{2})(10in.)(5 in.).

Now, it doesn't matter which order we multiply.

So we can begin by multiplying (1/2) (10 in.) to get 5 inches.

Now, (5 in.) (5 in.) is 25 in².

So the area of the triangle is 25 in².

A circle has an area of 225pift2 find the radius of the circle and find the diameter and circumference of the circle
RideAnS [48]

Answer:

  • radius: 15 ft
  • diameter: 30 ft
  • circumference: 30π ft

Step-by-step explanation:

The area is given in terms of the radius as ...

  A = πr^2

so we can find the radius as ...

  r = √(A/π)

For your circle, the radius is ...

  r = √(225π ft^2/π) = 15 ft

The diameter is twice the radius, so is ...

  d = 2r = 2·15 ft = 30 ft

And the circumference is π times the diameter:

  C = πd = π·30 ft = 30π ft

Please answer number 1? Thank you
Naddik [55]

Answer:

This is a normal distribution and we can use the standard score to compute for probabilities. We compute the standard score of the given.

Explnation:

z = (x - mu)/sd

z = (2625 - 2600)/50 = 25/50 = 0.5.

Consulting the z-table, P(z <= 0.5) = 0.6915.

P(z > 0.5) = 1 - P(z <= 0.5) = 1 - 0.6915 = 0.3085.

I hope this helped! <3
