A right triangle has one angle that measures 65°. What is the measure of the other acute angle?

1 answer:

8 0

The other angle is 25 degrees.

This is because the sum of all angles must add up to 180. To find the last angle, you must subtract the other angles you know from 180. We know the angle measurements are 65 and 90 (a right angle is 90)
180 - (65+90) = 25

The electronics company makes two types of switches. Type a takes 4 minutes to make and requires $3 worth of materials.Type b ta

Shalnov [3]

Let

x ------> number of switch type A

y -----> number of switch type B

Remember that

1 hour=60 min

32 hours=32*60=1,920 minutes

4x+5y=1,920 -------> equation 1

3x+5y=1,740 ------> equation 2

Solve the system of equations

Solve by graphing

using a graphing tool

see the attached figure

Solution is

x=180

y=240

therefore

<h2>the number of switch type A was 180</h2><h2>the number of switch type B was 240</h2>

Which formula is correct in computing 50% of the volume of the shape below?

elixir [45]

Answer:

Step-by-step explanation:

volume of a cylinder: V=πr^2h

so for 1/2 volume we can just multiply by 1/2

V = 1/2 (πr^2h)

plug in values r = 4.6 and h = 12.4

V= 1/2 π (4.6)^2 (12.4)

so the answer is D
