Answer
125,000 tons of garbage per landfill
Step-by-step explanation:
250 million total tons of garbage was sent to 2,000 landfills. Since it is assumed each landfill gets an equal amount of garbage, we can easily divide.
250,000,000 / 2,000 = 125,000 tons of garbage per landfill
henceforth, each landfill received 125,000 tons of garbage
A motorist covers distance of 180km in 3hours.calculate the speed at which the motorist was driving
Answer:
60 Km / hour
Step-by-step explanation:
average speed (S) is calculated as
S = [tex]\frac{D}{T}[/tex] ( D is distance and T time in hours )
here D = 180 and T = 3 , then
S = [tex]\frac{180}{3}[/tex] = 60 Km / hour

➪ Therefore, Option C is the correct choice!!~is cot 4 a is equal to tan (a - 20) where 4a is an acute angle find the value of a
Answer:
a = 22
Step-by-step explanation:
[tex]cot \: 4a = tan \: (a - 20)....(given) \\ \\ \implies \: tan(90 - 4a) = tan \: (a - 20) \\ [\because \: cot \theta = tan(90 \degree - \theta) ]\\ \\ \implies (90 - 4a) = tan(a - 20) \\ \\ \implies \: 90 + 20 = 4a + a \\ \\\implies \: 110 = 5a \\ \\ \implies \: a = \frac{110}{5} \\ \\ \huge \red{ \boxed{\implies \: a = 22}}[/tex]

Answer:
Slope = 3
y- intercept = (0, 10)
Step-by-step explanation:
the equation is given by y=mx+c where m is the slope
- At y-intercept, x is equal to 0
Therefore, y = 3(0) + 10
y = 0 + 10
y = 10
The value of X is 36 degrees less than the value of y. Find the values of X and Y!!
Answer:

How many gallons of 35% alcohol solution and 50% alcohol solution must be mixed to get 9 gallons of 40%
alcohol solution?
There needs to be____
gallons of 35 % alcohol solution and____
gallons of 50 % solution.
There needs to be 6 gallons of 35 % alcohol solution
and 3 gallons of 50 % solution.
======================================================
Explanation:
x = number of gallons of the 35% solution
y = number of gallons of the 50% solution
The two amounts must add to 9 gallons, so x+y = 9
This solves to y = 9-x
Since we want 9 gallons of 40% alcohol solution, this means we want 0.40*9 = 3.6 gallons of pure alcohol.
----------------
0.35x = amount of pure alcohol from the first batch
0.50y = amount of pure alcohol from the second batch
0.35x+0.50y = total amount of pure alcohol
Set that expression equal to the 3.6 figure calculated earlier (the total amount of pure alcohol we're after) and we get this equation
0.35x+0.50y = 3.6
----------------
Next, we replace y with 9-x and then solve for x.
0.35x+0.50y = 3.6
0.35x+0.50(9-x) = 3.6
0.35x+4.5-0.50x = 3.6
-0.15x+4.5 = 3.6
-0.15x = 3.6-4.5
-0.15x = -0.9
x = -0.9/(-0.15)
x = 6
We'll need 6 gallons of the 35% solution
Use this x value to find y
y = 9-x
y = 9-6
y = 3
We'll also need 3 gallons of the 50% solution

calculate the measure of each angle. find X
Solution:
Note that:
4x - 27 = 3x + 4 (Vertically opposite angles)Using the equation (4x - 27 = 3x + 4), solve for x.
4x - 27 = 3x + 4=> -3x + 4x - 27 = 3x + 4 - 3x=> x - 27 = 4=> x - 27 + 27 = 4 + 27=> x = 31The measure of x is 31.
Solve for X ~
[tex] \bf4x - 27 = 3x + 4[/tex]
[tex] \bf \: 4x - 3x = 4 + 27[/tex]
[tex] \boxed{ \bf \: x = 31}[/tex]
Now, Finding each angle⤵️[tex] \tt \: ∠1 = 2x + 21 \\ \tt \: = 2 \times 31 + 21 \\ \tt \: ∠1= 83 \degree[/tex]
[tex] \tt \: ∠2 = 4x + 27\\ \tt \: = 4\times 31 - 27 \\ \tt \: ∠2= 97 \degree[/tex]
[tex] \tt \: ∠3 = 3x + 4 \\ \tt \: = 3\times 31 + 4 \\ \tt \: ∠3= 97 \degree[/tex]

Step-by-step explanation:
We can solve this using substitution (substitute 4 for x)...
4+y=7
Subtract 4 from both sides
y=3
Answer:
y = 3
Step-by-step explanation:
x + y = 7
x = 4
4 + y = 7
y = 7 - 4

heather ate 3/6 of a box of cookies. Melody ate 3/5, who ate
more?
Answer:
Melody
Step-by-step explanation:
3/6 = 0.5
3/5 = 0.6
i.e. If it has the same numerator but different denominator the one with the smaller denominator will be bigger
Answer: Melody ate more.
Step-by-step explanation:
So, it would be Melody who ate more because
Over here:
Heather: ate 3 OUT of 6
Melody: ate 3 OUT of 5
Melody ate more because if you count up to 5 theres two cookies left, while Heather had 3 cookies left.

Jen traveled from Boston to Cape Cod at 60 mph. On her way back, the
traffic was bad and her return trip took 3 times as long. What was Jen's
average speed on the round trip?
Jen's average speed on the round trip will be 20mph
Distance and spedThe formula for calculating speed is expressed as:
Speed = Distance/Time
d = st
Let the time taken on Jen's way to Cape Cod be "t"
The time taken back to Boston will be t + 3
d1 = 60t
d2 = 60(t+3)
Since he traveled the same distance to and fro, hence;
Average speed = 60/3
Average speed = 20mph
Hence Jen's average speed on the round trip will be 20mph

Will give Brainlist pls answer
Answer:
Negative
Step-by-step explanation:
From the number line we see that [tex]m[/tex] is negative and [tex]n[/tex] is positive
The expression in the parentheses, [tex](-m . n^2)[/tex] is positive since
[tex]-m[/tex] is the negative of a negative number and the sign of that is positive
[tex]n^2[/tex] is positive since a positive (or negative) number squared is always positive
[tex]\frac{m}{n}[/tex] is a negative number. If you divide a negative number, the sign of the result is negative
So evaluating the whole expression [tex]\frac{m}{n} .( m . n^2)[/tex]
gives us a negative number multiplied by a positive number and the result is a negative number

7L + 4O = 9.30
The first equation can be made into the equation
28L + 21O = 38.15

The length of a rectangle is 5 m less than six times its width. If the perimeter is 200 m, find the length and width of the rectangle.
Answer:
Let W be the width of the rectangle. The length will then be 6W (six times the width). The area is length times width. if this equals 216, then you have an equation
(6W)(W) = 216
6W2 = 216
W2 = 36
W = 6.
The width is 6 ft and the length must then be 6W = 36 ft.
To find the perimeter, use the formula
P = 2L + 2W.
Plug in:
P = 2(36) + 2(6) = 72 + 12 = 84 ft.
The perimeter is 84 ft. (Remember that area has units length units squared and perimeter has units same as length.)
