Answer: 28.(3) 3 is repeating

Step-by-step explanation: When we start this problem, we should find out what answers Sue answered incorrectly. Since the problem already tells us that she answered 43 of them correctly(out of 60), all we need to do is subtract: 60-43

That’s when we learn that Sue answered 17 of the 60 questions incorrectly. Now, we need to convert 17/60 into a percentage.

If you didn’t know, in order to convert a fraction into a percentage, you have to first divide the numerator by the denominator, then multiply by 100.

So, 17 divided by 60 will give us 0.28(3). (The reason I put a parenthesis around 3 is that it is a repeating number). After, we have to multiple that decimal by 100 or simply move the decimal point by 2 places. Therefore, we get: 28.(3)

Answer:

These quotients are different because of what division means.

Step-by-step explanation:

When you divide you start with a total and break it into equal groups. If you started with three and broke them into groups of 1/5, that is different then starting with 1/5 and breaking into three groups.

As part of a new advertising campaign, a beverage company wants to increase the dimensions of their cans by a multiple of 1.12.
olga_2 [115]

Answer:

The new can can hold upto volume of 476.69 cubic centimeters.

Step-by-step explanation:

Diameter of the can = d = 6 cm

Radius of the can = r = 0.5d = 0.5 × 6 cm = 3 cm

Height of the can = h = 12 cm

Company wants to increase the dimensions of their cans by a multiple of 1.12. So, the new dimension will be:

r'= 3 cm × 1.12 = 3.36 cm

h' = 12 cm × 1.12 =13.44 cm

Volume of the = can = V

Volume of a cylinder = \pi r^2h

V=\pi r'^2h'

=3.14\times (3.36 cm)^2\times 13.44 cm=476.6808 cm^3\approx 476.68 cm^3

The new can can hold upto volume of 476.69 cubic centimeters.
