"whats the area of a circle with a circumference of 50.24 units"
pls help:)​

Answers

Answer:

200.96 units^2

Step-by-step explanation:

50.24/Pi = 16 (diameter)

16/2=8 (radius)

area = Pi(r^2)

area = 3.14(8^2) = 200.96 units^2

200.96
If the circumference is pi times the diameter then you divide 50.24 by 3.14 and get 16. So the if the diameter is 16 the radius is 8. 8 squared is 64 times pi is 200.96. Hope that helps

Given: f(1) = 3x– 7, 9(x) = 2x^2 – 3x +1, h(x) = 4x + 1, k(x) = –x^2+3
Find: (h o g) (x)

Answers

Answer:

(h o g) (x) = h(g(x))

Step-by-step explanation:

(h o g) (x) = h(g(x)) = 4(g(x))+1 = 4(2x^2 -3x + 1 ) + 1

= 4*2x^2 - 4*3x + 4*1 + 1

= 8x^2 - 12x + 4 + 1

find the slope of the line parallel to this equation: y=2/5x-4

Answers

Answer:

slope = [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{2}{5}[/tex] x - 4 ← is in slope- intercept form

with slope m = [tex]\frac{2}{5}[/tex]

Parallel lines have equal slopes

Thus the slope of a parallel line is m = [tex]\frac{2}{5}[/tex]

On a Saturday, Saul can cut 4 lawns in 6 hours. If Mitch can mow lawns at the same rate, how long will it take him to mow 9 lawns?

12 hours
12 3/4 hours
6 hours
13 1/2 hours

Answers

Answer:

13 1/2 is your answer.

Step-by-step explanation:

With the same ratio the time taken Mitch to mow 9 lawns will be 13 + 1/2 thus option (D) is correct.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given,

Saul can cut 4 lawns in 6 hours.

The ratio of hours to lawns will be as,

6/4

Suppose the time taken to mow 9 lawns to Mitch is x hours.

The ratio of hours to lawns will be as

x/9

Since the rate is the same thus ratio must be the same.

x/9 =  6/4

x = 6/4 x 9

x = 13.5 = 13 + 1/2

Hence"With the same ratio, the time taken Mitch to mow 9 lawns will be 13 + 1/2".

Two systems of equations are shown. The first equation in system B is the original equation in system A. The second equation in system B is the sum of that equation and a multiple of the second equation in system A.

Answers

Answer:

[tex]x = 3.875[/tex]

[tex]y = 2.375[/tex]

Step-by-step explanation:

See comment for complete question.

Given

A.

[tex]x + 3y = 11 => x + 3y = 11[/tex]

[tex]5x - y = 17 => 15x - 3y = 51[/tex]

[tex]16x = 62[/tex]

B.

[tex]x + 3y = 11[/tex]

[tex]16x = 62[/tex]

Required

Determine the values of x and y

The first equation in B is:

[tex]x + 3y = 11[/tex]

In (a): 5x - y = 17 is multiplied by 3, then added to x + 3y = 11.

So, the second equation is:

[tex]5x - y = 17[/tex]

Solving (a) & (b):

[tex]x + 3y = 11[/tex]  --- (1)

[tex]5x - y = 17[/tex] ---- (2)

Make x the subject in (1)

[tex]x + 3y = 11[/tex]

[tex]x = 11 - 3y[/tex]

Substitute [tex]11 - 3y[/tex] for x in [tex]5x - y = 17[/tex]

[tex]5(11 - 3y) - y = 17[/tex]

Open bracket

[tex]55 - 15y - y = 17[/tex]

[tex]55 - 16y = 17[/tex]

Collect Like Terms

[tex]- 16y = 17-55[/tex]

[tex]- 16y = -38[/tex]

Solve for y

[tex]y = \frac{-38}{-16}[/tex]

[tex]y = \frac{38}{16}[/tex]

[tex]y = 2.375[/tex]

Substitute 2.375 for y in [tex]x = 11 - 3y[/tex]

[tex]x = 11 - 3 * 2.375[/tex]

[tex]x = 11 - 7.125[/tex]

[tex]x = 3.875[/tex]

if x:y=3:5 find the ratio 3×+4y:8x +5y​

Answers

Answer:

29: 49

Step-by-step explanation:

Since x:y= 3:5,

[tex] \frac{x}{y} = \frac{3}{5}[/tex]

Cross multiply:

[tex]5x = 3y[/tex]

Divide by 5 on both sides:

[tex]x = \frac{3}{5} y[/tex]

[tex] \frac{3x + 4y}{8x + 5y} \\ = \frac{3( \frac{3}{5}y) + 4y }{8( \frac{3}{5}y) + 5y } \\ = \frac{ \frac{9}{5}y + 4y }{ \frac{24}{5}y + 5y } \\ = \frac{9y + 5(4y)}{24y + 5(5y)} \\ = \frac{9y + 20y}{24y + 25y} \\ = \frac{29y}{49y} \\ = \frac{29}{49} [/tex]

Thus, 3x+4y: 8x+5y= 29: 49.

express each of the following percentages as a fraction.28% 158%

Answers

Answer:

28% = 7/25 and 158% = 79/50

Step-by-step explanation:

To convert a percent into a fraction, you have to put the value of the percent over 100.

For 28%: 28/100

28 and 100 are both divisible by 4, so the fraction reduces to 7/25.

For 158%: 158/100

158 and 100 are both divisible by 2, so the fraction reduces to 79/50.  If you teacher doesn't want you do use improper fractions, then 79/50 can further be reduced and becomes [tex]1\frac{29}{50}[/tex].
