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.
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?
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
select the two binomials that are factors of this trinomial.
x^2+4x-32
a. x-8
b. x+8
c. x+4
d. x-4
Answer:
b and d
Step-by-step explanation:
Sum = 4
Product = -32
Factors = 8 , (-4)
x² + 4x - 32 = x² + 8x - 4x - 4*8
= x(x + 8) - 4(x + 8)
= (x + 8)(x - 4)

x+y=3
y=3x−17
Answer:
x=5 , y=-2
Step-by-step explanation:
rearrange y=3x-17 to -3x+y=-17
then subtract to get x or y
x+y=3
- (-3x+y=-17)
4x=20
x=20/4
x=5
then sub in the x value into one of the equations

Write the equation of the line with a slope of -5/4 and a y-intercept of 2.
a) y=1/4x+2
b) y=2x-5/4
c) y=-1/4x+2
d) y=-5/4x+2
Answer:
D, y=-5/4x+2
Step-by-step explanation:
the slope always comes before "x", and the y-intercept comes last when written in slope intercept. So y=-5/4x+2 is correct.

I need the answer to this
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.
I Hope This Helps :)

If a barrel is 1/5 full and holds 16 litres how many litres will it hold when 1/2 full how does it fill
Answer:
40liters
Step-by-step explanation:
Given data
1/5 full holds 16 liters
1/2 full barrel will hold???
Let 1/2 full barrel hold x liters
1/5 holds 16 liters
1/2 will hold x
cross multtiply
1/2*16= x/5
8= x/5
x= 8*5
x= 40 liters
Hence 1/2 full will hold 40liters

What is an Arithmetic operation?Combining operands with a single arithmetic operator specifies an arithmetic operation. The built-in functions ADD, SUBTRACT, DIVIDE, and MULTIPLY can also be used to specify arithmetic operations. in general, we use PEMDAS for calculating various arithmetic operations.
Given 25% of the marbels ar red. and also given 45 marble are red.
Hence Total marble will be,
Total marbles = [tex]\frac{45* 100}{25}[/tex] = 180.
Therefore the total number of marbles in the jar is 180.

Five less than twice the value of a number is equal to three times the quantity of
four more than one-half the number. What is the
number?
a. Let x be the number. Write and solve an equation to find x. Show your work.
b. Does the solution of your equation solve the original problem? Explain.
Answer:
a) x = 34
b) yes, it checks out
Step-by-step explanation:
2x - 5 = 3(4 + 1/2x)
multiply both sides by 2 to eliminate fraction
2[2x - 5 = 3(4 + 1/2x)] = 4x - 10 = 24 + 3x
x - 10 = 24
x = 34
check
2(34) - 5 = 3(4 + 34/2)
68 - 5 = 3(4 + 17)
63 = 3(21)
63 = 63
