Kate is 3 years old. Her brother, Scott is 10 years old. A. What is the ratio of Scott's age to Kate's age. B. How many times ol

Dafna1 [17]

Answer:Scott is over 3 times older that Kate

Step-by-step explanation:

Kate is 3 years old. Her brother, Scott is 10 years old.

A) The ratio of Scott's age to Kate's age would be Scott's age divided by Kate's age. It becomes

10/3

B) To determine how many times older than Kate is Scott, we would express the ratio of their ages in decimal. Therefore

10/3 = 3.33

Therefore, Scott is over 3 times older that Kate

The state of mishgan recored an all time high snowball of 355.9 inches during the winter of 1978-79 its lowest snowfall of 81.3

Rama09 [41]

Answer:

274.6 inches more snowfall Michigan received during the winter of 1978-79 than in 1930-31.

Step-by-step explanation:

Given:

The state of Michigan recorded an all time high snowfall of 355.9 inches during the winter of 1978-79.

Its lowest snowfall of 81.3 inches was recorded during the winter of 1930-31.

Now, to find how much more snowfall did Michigan received during the winter of 1978-79 than in 1930-31.

The snowfall in 1978-79 = 355.9 inches.

And, the snowfall in 1930-31 = 81.3 inches.

So, to get the how much more snowfall in 1978-79 than 1930-31 we subtract:

Snowfall in 1978-79 - Snowfall in 1930-31.

$355.9\ inches-81.3\ inches = 274.6\ inches.$

Therefore, 274.6 inches more snowfall Michigan received during the winter of 1978-79 than in 1930-31.

What does dilation of a triangle mean?

NikAS [45]

Answer: Dilation is a technique for creating similar figures. Each point is stretched outwards from the center point D by multiplying distances by the scale factor. (Outwards if the scale factor is bigger than 1.) Move the points A, B, and C to change the shape of the triangle.

Find the volume and surface area of the composite figure. Give your answer in terms of π.

irakobra [83]

Answer:

V = 240π cm^3 , S= 168π cm^2

Step-by-step explanation:

The given figure is a combination of hemi-sphere and a cone

Volume:

For volume

r = 6 cm

h = 8 cm

$Volume\ of\ cone = \frac{1}{3}\pi r^2h\\= \frac{1}{3}\pi (6)^2*8\\=\frac{1}{3}\pi *36*8\\=\frac{288}{3}\pi\\=96\pi cm^3 \\\\Volume\ of\ hemisphere = \frac{2}{3}\pi r^3\\=\frac{2}{3}*\pi * (6)^3\\=\frac{2}{3}*\pi *216\\=\frac{432}{3}\\=144\pi cm^3 \\\\Total\ Volume= Volume\ of\ cone + Volume\ of\ hemisphere\\= 96\pi +144\pi \\=240\pi cm^3$

Surface Area:

For this particular figure we have to consider the lateral area of the cone shape and surface area of the hemisphere

We have to find the lateral height

$l = \sqrt{r^2+h^2}\\ l = \sqrt{(6)^2+(8)^2} \\l= \sqrt{36+64}\\ l = \sqrt{100}\\l = 10cm\\\\Surface\ area\ of\ cone = \pi rl\\= \pi (6)(10)\\=\pi *60\\=60 \pi\ cm^2\\\\Surface\ area\ of\ hemisphere = 2\pi r^2\\= 2 \pi * (6)\\= 2 \pi *36\\= 72 \pi\ cm^2\\\\Total\ surface\ Area = Surface\ area\ of\ cone + Surface\ area\ of \ hemisphere\\= 60 \pi + 72 \pi\\=132 \pi\ cm^2$

Hence the first option is correct ..
