Ewan has a mango farm that is 75 feet X
50 feet, and he also purchases a 20 feet X
10 feet plot of land. Find the total area of
the farm.
Answers
Answer:
3950 feet squared
Step-by-step explanation:
So first you have to multiply 75 by 50, so that is 3750.
Next you have to multiply 20 by 10 and you get 200.
Finally you had both 3750 and 200 in order to get 3950 and that is why the total area of the farm is 3950 feet squared.
The amount of lawns mowed is proportional to the number of hours that Lana works. The equation below represents the proportional relationship between lawns mowed (m) and the number of hours worked (h). M=4h How many lawns can Lana mow each hour?
Answers
Answer:
0.25 lawns
Step-by-step explanation:
The computation of the number of lawns each hour is shown below;
M represent the mowed
ANd, number of hours represent h
Also
M = 4h
That means one mowed = 4 hours
So for one hour = 1 ÷ 4 = 0.25 lawns

Answers
Answer:
8 Hours
Step-by-step explanation:
Since 4 painters painting one house takes 14 hours, then one person would take 56 hours to paint the whole house. Hence, 4 x 14 = 56. If 7 people painted the house, then 8 hours would be needed since 56 / 7 = 8.
4 people x 14 hours = House
56 hours = House
56 hours is required to paint a house.
7 people x H hours= House
7 people x H hours = 56
(7 people x H hours)/ 7 = 56 / 7
You divide 7 on both sides to isolate H on one side.
H hours = 8
So H = 8 which is the amount of hours needed.

Mr. Robison rides 136 miles per hour on his bike ride. He wants to ride more than 360 miles at the same rate during his next bike ride. Which inequality represents all possible values for b, the number of hours Mr. Robison must bike to ride more than 360 miles rounded to the nearest hundredths?
Answers
Answer: See explanation
Step-by-step explanation:
From the equation, we are informed that Mr. Robison rides 136 miles per hour on his bike ride and that he wants to ride more than 360 miles at the same rate during his next bike ride.
The inequality that represents all possible values for b, the number of hours Mr. Robison must bike will be:
136b > 360
b > 360/136
b > 2.65
Therefore, Me Robinson must bike for more than 2.65 hours

Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts and uses 2 of the pieces on gifts.How much ribbon does she use ? Solve this problem any way you choose.
Answers
Answer: 6 2/3
Step-by-step explanation:
Julie has 10 yards of ribbon.She divides the ribbon into 3 equal parts. This means that each ribbon will be:
= 10/3
= 3 1/3
She then uses 2 of the pieces on gifts. The amount of ribbon that she use will be:
= 3 1/3 × 2
= 10/3 × 2
= 20/3

Answer:
x=10, x=-2
Step-by-step explanation:
x^2-5x-3x+15=35
x^2-8x-20=0
Multiply to -20, add to -8: -10, 2
(x-10)(x+2)=0
x=10, x=-2
Answer:
x = −2 or x = 10
Step-by-step explanation:
(x - 3)(x - 5) = 35
x^2 − 8x + 15 = 35
x^2 − 8x + 15 − 35 = 35 − 35
x^2 − 8x − 20 = 0
(x+2)(x−10) = 0
x + 2 = 0 or x − 10 = 0
x = −2 or x = 10

2. Distribute. You will end up with 0 = -3n
3. Divide both sides by -3. n = 0
Step-by-step explanation:
Answer:
n=0
Step-by-step explanation:
3(-4+4)+5n=2n

5n=2n
subtract 2n on both sides
3n=0
divide by 3 on both sides

This is an equation! Solutions: t=-5.
Answer: t= -1/3

divide 3 into 3t and -1
the 3 in 3t is canceled out, leaving us with t, therefore t= -1/3

3f^4g^3 x 8fg^4 / (6f^2g^3)^2 how do you do this? I know the answer is 2/3fg but how do you get 0.666... into that fraction form?
Answers
9514 1404 393
Answer:
0.666... = 6/9 = 2/3
Step-by-step explanation:
The repeating decimal 0.666... can be turned to a fraction as follows.
Let x represent the value of the number. Then 10x is ...
10x = 10(0.666...) = 6.666...
Subtracting x gives ...
10x -x = 6.666... - 0.666... = 6.000...
9x = 6
Dividing by 9 and simplifying, we have ...
x = 6/9 = 2/3
__
It can be worthwhile to remember that 1/9 = 0.111... repeating.
Then 3/9 = 1/3 = 3(0.111...) = 0.333... repeating
and 6/9 = 2/3 = 6(0.111...) = 0.666... repeating
Most calculators will round the last digit of 2/3 so that it is a 7. So, you may see ...
2 ÷ 3 = 0.6666667 or 0.66666666667
or something similar, depending on your calculator. It is up to you to recognize this as probably a representation of 2/3. Some calculators will display the number as a fraction, so you don't have to guess.
_____
Additional comment
A similar method is used to convert repeating decimals of other lengths to fractions. In general you multiply by 10^n, where n is the number of repeating digits. Then proceed as above: subtract x, divide by the coefficient of x. You will find you are always dividing by a number that has as many 9's as there are repeating digits.

Peter makes a base monthly salary of $2,500. As a vendor, he must sell $15,000 worth of items per month. He also makes an 18% commission on all sales beyond the monthly quota. If Peter sold $24,600 worth of items this month, what is his total salary for the month including base salary and commission to the nearest dollar?
Answers
Answer:
Monthly salary= $4,228
Step-by-step explanation:
Giving the following information:
Fixed salary= $2,500
Sales commission= 10%
Sales= $24,600
To calculate the monthly salary, we need to use the following formula:
Monthly salary= fixed income + commission
Commission= (24,600 - 15,000)*0.18
Commission= $1,728
Monthly salary= 2,500 + 1,728
Monthly salary= $4,228
