Answer:

There is 3 out of 4 chance you will get one head.

You are not guaranteed to get a head

Step-by-step explanation:

Lets determine the sample space

HH  HT  TH  TT

These are the 4 things that can happen when we flip to coins

Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees none of the other lines add up to 180 degrees and are also part of a vertical pair

How many cubes eith side lengths of 1/4 cm does it take to fill the prism? Please help
valina [46]

Step-by-step explanation:

In order to find Volume for a rectangle use the formula: L * W * H

2 1/4 * 3/4 * 1 1/4 = 2 7/64

A cube with the side lengths of 1/4:   1/4 * 1/4 * 1/4 = 1/64

Divide 1/64, by the prisms volume, 2 7/64 to get 135.

I'm not sure if this is right, but I hope that helps! :)

10 more than 2 times a number is equal to 2 times the number plus 50. What is the number?
PSYCHO15rus [73]

Answer:

y = 40 is the answer

Step-by-step explanation:

Let the number be y

10 more than 2 times a number = 10 + 2×y

equal to 2 times the number plus 50. = 2 × y + 50

10 + 2y = 2y + 50

combine the like terms

2y - 2y =50 - 10

0 = 40

the number supposes be 40 but the number is represented by 0

i think some thing is missing in your question

y supposes be 40 not 0 = 40

Hope this helps!
