Anita can paint the shed in 5 h. If Kris helps her, they can paint the shed in 3 h. How long will it take Kris to paint the shed alone?

Answers

Anita can paint the shed in 5 hours. If Kris helps her, they can paint the shed in 3 hours. How long would it take Kris to paint the shed alone?
----
Anita rate = 1/5 job/hr
Together rate = 1/3 job/hr
Kris rate = 1/x job/hr
Equation:
rate + rate = together rate

1/x + 1/5 = 1/3
----
Multiply thru by 15x to get:
15 + 3x = 5x
2x = 15
x = 7.5 hrs (time for Kris to do the job alone)

6x(2+32/16) is greater than,less than or equal to (6x2)+32/16

Answers

32/16=2
2+2=4
4x6=24

6x2=12
32/16=2
12+2=14

6x(2+32/16) is greter than (6x2)+32/16
6×(2+32/16) is greater than (6×2)+32/16 because it equals 24 while the latter equals only 14.

A horse corral is situated on a triangular plot of land. Two sides of the plot are 150 feet long and they meet at an angle of 55°. A fence is to be placed along the perimeter of the corral. How much fencing material is needed?a. 125 ft
b. 138.5 ft
c. 288.5 ft
d. 438.5 ft

Answers

Answer : d. 438.5 ft

The diagram for the given statement is attached below.

Two sides AB and AC are equal so the angle B = angle C

WE know sum of three sides of a triangle = 180

angle A + angle B + angle C = 180

55 + B + C = 180

B + C = 180 -55 = 125

B and C are equal so we divide 125 by 2

angle B = 62.5 and angle C = 62.5

Now we apply sin law

(sin A)/(a) = (sin B)/(b)

(sin 55)/(a) = (sin 62.5)/(150)

150 * sin(55) = sin(62.5) * a

122.8728066 = sin(62.5) * a

a = ( 122.8728066)/(sin(62.5))

a= 138.52 feet

To find perimeter we add all the sides

150 + 150 + 138.52 = 438.52 feet

Robert is making 5 batches of lemonade. Each batch requires 2 1\3 quarts of water. How much water will Robert need?
Express your answer in simplest form.

A.10 1\3
quarts

B.10 2\3
quarts

C.11 1\3
quarts

D.11 2\3
quarts

Answers

2 1/3 quarts per batch, and five batches, so you multiply 2 1/3 x 5.

2 1/3 = 7/3   and   5 x 7/3 = 35/3 which simplifies to 11 2/3, so D. is the answer.

In the scientific value of 5.893 x 10n. The standard value is 0.00005893 what is n? To better illustrate this phenomenon, we can explain it further under the rules of scientific notation. 
For example. 
1.  3 x 10^3 = 3 x 100 = 300 
2.  3 x 10^-3 = 3 x 0.001 = 0.003 

Solution: 
0.00005893 = 5.893 x 0.00001 = 5.893 x 10^-5   
n= ^-5

Answer:

it dosnt make sense because 0.007 is 10x 0.07
