Mathematics
1 answer:
o-na [289]3 years ago
6 0

Answer:

r = 35cm

Step-by-step explanation:

Given

C = 220cm

\pi = \frac{22}{7}

Required

Determine the radius

Circumference (C) is calculated as:

C = 2\pi r

Where r represents radius

Substitute values for C and \pi

220cm = 2 * \frac{22}{7} * r

220cm =  \frac{44}{7} * r

Multiply through by 7/44

\frac{7}{44} * 220cm =  \frac{7}{44} * \frac{44}{7} * r

r = \frac{7}{44} * 220cm =

r = \frac{7 * 220cm }{44} =

r = \frac{1540\ cm}{44}

r = 35cm

<em>Hence, the radius is 35cm</em>

The Westside Bakery uses 310 pounds of flour to make 1,000 loaves of bread. Each loaf
DanielleElmas [232]

Answer:

310 / 1000 = 0.31 pounds

Step-by-step explanation:

When dividing by a number that is 1 less 0 than how many digits the number has, we can move the decimal point the number of times zero is repeated at the end of the number.

1000 has 3 zeroes, so we move the decimal point 3 moves to the left.

So, we do this:

After 0 moves: 310

After 1 move: 31.0

After 2 moves: 3.10

After 3 moves = 0.310

0.310 is the same as 0.31

Therefore, 0.31 pounds of flour are in each loaf.

Chi has a rectangular window planter that is 8 inches high, 18.5 inches long, and 7 inches wide. If she fills the planter halfwa
Ghella [55]
Your answer would be 518 Cubic inches.

18.5 * 7 = 129.5
129.5 * 8 = 1036 (Full planter aka not what we want)
If we take the height and divide it be 2 then we would get 4in (halfway full)
 So 129.5 * 4 = 518 Cu.

I hope I helped!

The graph of g(x)=(0.5)x+4 is shown. Which equation is an asymptote of this function? y = 0 y = 4 x = 4 x = 0
Alexandra [31]

we are given

g(x)=(0.5)^x+4

we can see that

there is no value of x for which g(x) is not defined

so, no vertical asymptote exists

now, we will find horizontal asymptote

\lim_{x \to \infty} g(x)= \lim_{x \to \infty}((0.5)^x+4 )

\lim_{x \to \infty} g(x)= (\lim_{x \to \infty} (0.5)^x+\lim_{x \to \infty} 4 )

\lim_{x \to \infty} g(x)= 0+4

so, we get

horizontal asymptote as

y= 4............Answer

at a certain university, 23% of students will graduate with a math degree, 31% will graduate with a computer science degree and
Tpy6a [65]
<h3>Answer:  B) 47%</h3>

Work Shown:

A = event that the person has math degree

B = event that the person has a computer science degree

P(A) = 0.23, since 23% of the people have a math degree

P(B) = 0.31, similar reasoning as above, just different number

P(A and B) = 0.07

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.23 + 0.31 - 0.07

P(A or B) = 0.47

The decimal value 0.47 then converts to 47% after moving the decimal 2 spots to the right.

There's a 47% chance that we pick someone who has a math degree or a computer science degree (or both).

It might help to set up a venn diagram to see why that formula above works.
