Forty percent of the 70 buttons in the box had 5 holes

Mathematics
1 answer:
ivanzaharov [21]3 years ago
7 0

Answer: a. 0.6

b. 42 buttons

Step-by-step explanation:

a. What fraction of the buttons did not have 5 holes?

Since forty percent of the 70 buttons in the box had 5 holes, the number of buttons in the box that doesn't have 5 holes will be:

= 100% - 40%

= 60%

= 60/100

= 0.6

b. How many buttons did not have 5 holes?

This will be:

= 60% × 70

= 0.6 × 70

= 42 buttons

-8.5 belongs on whole numbers, integers or rational number?
Feliz [49]

Answer:

-8.5 is a rational number

Step-by-step explanation:

The whole numbers are all the numbers you can reach if you start at 1 (or 0, if that's your thing) and count forward - 1, 2, 3, 4, on and on forever. The integers are all the numbers we can get by adding and subtracting two whole numbers - this includes situations like 3 - 4, where we're "taking away" more than we have: we simply invent numbers less than zero, the negatives, and that gives 3 - 4 a value - the number -1.

So we can add, subtract and multiply any of these numbers together and we end up somewhere else our world of integers, but the moment we want to ask a question like "what numbers are between 0 and 1?" the integers just aren't enough. We need fractions, and for that purpose we create the rational numbers, which include all the fractional parts between integers, as well as the integers themselves.

-8.5 is halfway between the integers -8 and -9, and since it has a fractional part, it must be a rational number.

What is the measure of ZB?<br> 28<br> 36<br> B<br> [?] degrees<br> Enter
Sindrei [870]
All triangles have a measurement of 180 degrees. Therefore, we can use this information to make an equation to find the value of angle B.

Angle B = 180 - (28 + 36)
Angle B = 180 - 64
Angle B = 116

So, angle B is equal to 116 degrees.
