Step-by-step explanation:

Step one:

given data

Mohammed is running the 800m race

He has completed 25 percent= 25%

Step two:

Let us find 25% of 800

=25/100*800

=0.25*800

=200 m

Answer:

E) 613.9 m2

Step-by-step explanation:

sum of measures of interior angles of a polygon of n sides:

(n - 2)180

For a pentagon:

(5 - 2)180 = 3(180) = 540

measure of one interior angle of a regular pentagon:

540/5 = 108

Draw a segment from the center of the pentagon to the top vertex. Now you have a right triangle.

The triangle has a 90 deg angle where the segment in the figure meets the side of the pentagon. Let half of the side of the pentagon be x. x is a side of the right triangle.

For the 54 deg angle in the triangle, 13 m is the opposite leg, and x is the adjacent leg.

tan A = opp/adj

tan 54 = 13/x

x = 13 m/tan 54 = 9.445 m

x is half of the side of the pentagon.

2x is the side of the pentagon.

2x = 2(9.445 m) = 18.89 m

The given 13 m segment is the apothem of the pentagon.

A = nsa/2

where n = number of sides, s = length of 1 side, a = length of apothem

A = (5)(18.89 m)(13 m)/2

A = 613.9 m^2

Answer: E) 613.9 m2

Answer:

$2.7

Step-by-step explanation:

We find the amount that was marked up

Jermaine buys T-shirts for $6 each and marks up the price by 45%.

The marked up amount = 45% × $6

= 45/100 × $6

= $2.7

Therefore, the amount Jermaine charges more for each T-shirt sold is $2.7

Answer:

26

Step-by-step explanation:

Let 10 be a, and 24 be b, and the undefined hypotenuse be c.

[tex]a^2 + b^2 = c^2[/tex]

[tex]10^2 + 24^2 = c^2[/tex]

100 + 576 =  c

c = 676

[tex]\sqrt{100} + \sqrt{576} = \sqrt{676}[/tex]

[tex]10^2 + 24^2 = 26^2[/tex]

c = 26

The value of the undefined line is 26.

Answer:

It took Mr. Holloway 28 weeks to make 7 guitars.

Step-by-step explanation:

The question is incomplete, but if we are trying to find out how many weeks it would take him to make 7 guitars then the answer would be 28.

First you have to find out how many weeks it takes him to make 1 guitar.

8 ÷ 2 = 4 (4 weeks to make 1 guitar)

Then you have to multiply 4 by 7 since it takes 4 weeks to make 1 guitar.

4 * 7 = 28 (28 weeks to make 7 guitars)

Answer:

28 weeks

Step-by-step explanation:

Answer: 13 metres.

Step-by-step explanation:

Answer: The length would be 13 meters.

Step-by-step explanation:

Area = L*W

52 = 4L

52/4 = L

13 = L

Answer:

5

Step-by-step explanation:

since the sides are the same size, then the equation should be combined into x+2=2x-3

then subtract an x from both sides: 2=x-3

then add 3 to both sides: 5=x

and you have your answer

hope this works

Answer:

x=5

Step-by-step explanation:

x+2=2x-3

-x on both sides=

2= x-3

then -2 on both sides

0= x-5

this means that x must be 5 so that positive 5- negative 5 equals 0 :)

Answer: 840 people

Step-by-step explanation:

They surveyed 40 people in total and out of those 40, 21 said that sausage pizza was their favorite pizza.

The percentage of people who prefer sausage pizza is therefore:

= 21/40 * 100%

= 52.5 %

If there are 1,600 people in the festival and we assume that the sample is a representation of the people there, the estimated number of people who prefer sausage pizza will be:

= 52.5% * 1,600

= 840 people

12/x2+7x

hope it is right

Answer:

12 / x2 + 7x

Explanation:

Multiply the fractions

12/ x · (x + 7)

Distribute x

12/ x2 + 7x

Tank A capacity = 550 gallons       66% x 550 gallons = 363 gallons in Tank A

How about the water in tank B?

ratio of  11: 15      11/15 = 550/x          550 * 15/11 = cap B = 750 gal       53% 0f 750 = .53 x 750 = 397.5 gal in tank B

Answer:

Step-by-step explanation:

Yesss

Answer:

Combined

Step-by-step explanation:

Explore the relationship between the general forms of variation :

Direct Variation :

x varies directly as y ; x = kx

Inverse Variation :

x varies inversely as y ; x = k/x

Joint : x varies jointly as y and Z ; x = kxz

combined :

x varies directly as y and inversely as z ; x = kx * 1/ ; x = kx/z

Where k is the proportionality constant.

In the equation given above :

We have a combination of joint and inverse variation : V = 5ng

V varies jointly as n and t and inversely as m

V α k * n * t * 1 / m

V = Knt /m

Where, k is proportionality constant.
