Which of the following could represent the scale factor of the smaller figure to the larger figure?

Mathematics
1 answer:
Reptile [31]3 years ago
8 0

Answer:

It could be 2:5 or 6pi:15pi

Step-by-step explanation:

If you write the ratio of the surface area as a fraction, you would get \frac{20\pi *yd^{2} }{125\pi *yd^{2} }. Simplifying it would leave \frac{4}{25}. But this is NOT the answer because that is the ratio of the surface area. You have to square root it to find the scale factor. The square root is \frac{2}{5}. The answers would be 2:5 and 6pi:15pi.

Mrs. Simpson is frosting circular sugar cookies. Each cookie is 7 cm in diameter. How many square inches will she need to frost
Alexus [3.1K]

Answer:

51.92 square inches

Step-by-step explanation:

Area of a circle = (pi)(r^2)

if the diameter is 7, the radius is 3.5

A = 3.14 x 3.5

A = 10.99 cm^2 for one cookie

10.99 x 12 for a dozen = 131.88 cm^2

converting cm to inches, you divide by 2.54

131.88/2.54 = 51.92 square inches.

What is the y-intercept of f(x)=(1÷4)<br>​
Hunter-Best [27]
Y-intercept means x=0 but judging from the question you only gave f(x) which means Y

And so I think the only valid answer there is

Y= 0.25
X=0

Owen received $100 for his birthday.he wants to spend 2/10 of his money on a video game.he wants to spend 55/100 of his money on
babymother [125]
An easy way to solve fraction problems like this is to make each fraction have the same denominator.  Since he has $100, the denominator will be 100.
2/10=?/100    10*10=100  1*10=20   20/100 of his money he wants to spend on video games
55/100 already has 100 as its denominator, so he wants to spend 55/100 on a skateboard.
3/10=?/100   10*10=100   3*10=100  30/100 is how much he wants to spend on comic books.
Add all of the fractions together to see how much he wants to spend and if he has enough.
20/100+55/100+30/100=105/100
He wants to spend $105, which is $5 more than he has.
