The sum of two consecutive interferes is at least 7 (n and n + 1 represent two interferes

vesna_86 [32]

Consecutive integers are 1 apart so they are n and n+1

their sum (add) is at least 7
sum>7

sum means add
n+n+1>7
2n+1>7
minus 7 both sides
2n>6
divide 2
n>3

the smaller number mist be at least 3, (making the bigger number at least 4)

Every two years, there is a local election in a small town. In 2015, a total of 29,000 voters turned out in the election. In 201

Keith_Richards [23]

Answer:

29730 voters

Step-by-step explanation:

so:

in 2017- 16/100=0.16 x 29,000=4640 so 29,000-4640=24360 voters

in 2019-22/100=0.22 x 24369=5361.18 so 24369+5361.18=29730.18 voters

I hope this helped

The circumference of heileen’s basketball is 30 inches. What is the approximate diameter of the basketball?

adoni [48]

Answer:

9.55 in

Step-by-step explanation:

The formula for the circumference of a circle (or the circum. of a basketball) is C = πd, where d is the diameter.

Here C =30 in = πd, so

d = (30 in) / π

= 9.55 in, approx.

A local improvement store sells different sized of storage sheds. The most expensive shed has a footprint that is 15 feet wide b

Mekhanik [1.2K]

Answer:

Question 1: Are the footprints of the two sheds similar?

Yes, the two sheds are similar.

Question 2: Tell whether the footprint of the least expensive shed is an enlargement or a reduction,

It is a reduction

Question 3: Find the scale factor from the most expensive shed to the least expensive shed

The scale factor is 3/2

Explanation:

Question 1: Are the footprints of the two sheds similar?

The footprints of the two sheds will be similar if their measures are proportional.

The ratio of the measures of the footprint of the most expensive shed is:

width/length = 15 feet / 21 feet = 5 / 7

The ratio of the measures of the footprint of the least expensive shed is:

width/length = 10 feet / 14 feet = 5 / 7

Since, the two ratios are equal, you conclude that the corresponding dimensions are proportional and the two sheds are similar.

Question 2: Tell whether the footprint of the least expensive shed is an enlargement or a reduction.

A reduction is a similar transformation (the image and the preimage are similar) that maps the original figure into a smaller one.

Since the dimensions of the foot print of the least expensive shed, 10 feet wide by 14 feet long, are smaller than the dimensions of the most expensive shed, 15 feet wide by 21 feet long the you conclude that the former is a reduction of the latter.

Question 3: Find the scale factor from the most expensive shed to the least expensive shed.

To find the scale factor from the most expensive shed to the least expensive shed, you divide the measures of the corresponding dimensions. You can do it either with the widths or with the lengths.

Using the widths, you get:

width of the foot print of the most expensive shed / width of the foot print of the least expensive transformation

15 feet / 10 feet = 3/2.

That means that the scale factor from the most expensive shed to the least expensive shed is 3/2.

Using the lenghts, you should obtain the same scale factor:

length of the foot print of the most expensive shed / length of the foot print of the least expensive transformation

21 feet / 14 feet = 3/2. Such as expected.
