The shape of the top surface of a table is a trapezium. Find its area
if its parallel sides are 1 m and 1.2 m and perpendicular distance
between them is 0.8 m.
1.
Answer:
0.88m²
Step-by-step explanation:
Area of a trapezium = 1/2(a+b)h
a and b are the parallel sides
h is the height
Given
a = 1m
b = 1.2m
h = 0.8m
Substitute
Area of the trapezium = 1/2(1+1.2)(0.8)
Area of the trapezium = 1/2(2.2)(0.8)
Area of the trapezium = 1.1 * 0.8
Area of the trapezium = 0.88m²
A train company charges a flat fee of $175, plus $2.50 per mile for a bus. If the band paid exactly $1,875 for three buses, how far did the band travel?
Answer:
680 miles
Step-by-step explanation:
1,875=2.5x+175
Minus 175 each side.
1,700=2.5x
Divide both sides by 2.5
680=x
If the band travels 680 miles for $2.50 each mile, plus the flat fee of 175. The total will be 1,875.

Rewrite the equation below so that it does not have fractions. 3/4x+2=5/6 do not use decimals in your answer.
Answer:
18x + 48 = 20
Step-by-step explanation:
Rewrite the equation below so that it does not have fractions. 3/4x+2=5/6 do not use decimals in your answer.
We are given the expression:
3/4x + 2=5/6
= 3x/4 + 2 = 5/6
Rewriting the Equation so that it does not have fraction is, we Multiply both sides by the 24
= 3x/4 × 24 + 2 × 24 = 5/6 × 24
= 3x/4 × 24 + 48 = 5 × 4
= 3x × 6 + 48 = 20
= 18x + 48 = 20
Therefore, the Equation without fractions = 18x + 48 = 20

write an expression to represent the length is 6 feet longer than the width
Step-by-step explanation:
Let l be the length of the room, and w be the width.
If the length is 6 feet longer than twice the width, then we can say l = 2w+6
Knowing that the formula for the perimeter of a rectangle is P = 2l+2w, and knowing that P=144 ft, we can say that 2L + 2w= 144 ft.
To find the dimensions, we plug our value for l into our perimeter equation
This gives us the following equation: 144= 2(2w+6) + 2w, which simplifies to 144=4w+12+2w, which further simplifies to 144= 6w+12
To get w on one side of the equation, we subtract 12 from each side, which gives us 132=6w
Dividing each side by 6, we determine that w= 22 ft.
Plugging this value back into our first equation we see that l= 2(22)+6
So l= 50 ft.
So, the dimensions of the room are as follows: length is 50 ft., width is 22 ft.
Answer:
L = w + 6
Step-by-step explanation:
We need to write an expression for the length.
We know that the length is 6ft longer than the width.
Make your expression:
We will represent length as "L" and width as "w".
L = w + 6
This would be our expression since we know that no matter what, the length will be 6ft more than the width, therefore you would add 6 to the width to get your length.

Elisa withdrew $20 at a time from her bank account and withdrew a total of $160. Frances withdrew $49 at a time from his bank account and withdrew a total of $196. Who made the greater number of withdrawals?
Answer: Elisa
Step-by-step explanation:
Elisa withdrew $20 at a time from her bank account and withdrew a total of $160. The number of times she made a withdrawal will be:
= $160 / $20
= 8 times
Frances withdrew $49 at a time from his bank account and withdrew a total of $196. The number of times she made a withdrawal will be:
= $196 / $49
= 4 times.
From the calculations above, we can see that Elisa made the greater number of withdrawals.

Answer:
For Part A the answer is that you're supposed to move the line one unit up on the y-axis.
Step-by-step explanation:
What is the value of y in the product of powers below?
Answer:
The value of y = 0
Step-by-step explanation:
Given the equation
[tex]8^3\cdot 8^{-5}\cdot 8^{\:y}=8^{-2}[/tex]
Apply exponent rule: [tex]a^b\cdot \:a^c=a^{b+c}[/tex]
so
[tex]8^3\cdot \:\:8^{-5}=8^{3-5}=8^{-2}=\frac{1}{8^2}=\frac{1}{64}[/tex]
Thus, the equation becomes
[tex]\frac{1}{64}\left(8\:^y\right)=\frac{1}{64}[/tex]
Divide both sides by 1/64
[tex]\frac{\frac{1}{64}\left(8\:^y\right)}{\frac{1}{64}}=\frac{\frac{1}{64}}{\frac{1}{64}}[/tex]
[tex]8\:^y=1[/tex]
Solve Exponent
[tex]8\:^y=1[/tex]
Take log of both sides
[tex]\:log\left(8\:^y\right)\:=log\:\left(1\right)[/tex]
[tex]y\cdot \left(log\left(8\right)\right)=log\left(1\right)[/tex]
[tex]y\:=\frac{log\left(1\right)}{\left(log\left(8\right)\right)}[/tex]
[tex]y = 0[/tex]
Therefore, the value of y = 0
Write the number 2.3 x 10^4 in standard form.
Answer:
23000
Step-by-step explanation:
The 10^4 indicates that the decimal moves to the right 4 times. So 2.3 x 10^4 to standard/regular form would be 23000.
The ordinary form of : [tex]2.3* 10^{4}[/tex] is 2,30,000
What is standard form?Standard form is like scientific notation and is typically used in science and engineering. A number is written in standard form when it is represented as a decimal number times a power of 10.
The number is in standard form is : [tex]2.3* 10^{4}[/tex]
[tex]2.3* 10^{4}[/tex] = 2.3 x 10000
= 2,30,000

1 Movies cost $10.25 per ticket, popcorn costs $4.99, and candy bars costs $3.50. How much would it cost for 3 people to go the movies and each person will get 1 popcorn and 1 candy bar?
Answer:
$56.22
Step-by-step explanation:
Since movies cost $10.25 per ticket:
total cost for tickets: 3($10.25)= $30.75
Next, each person got one popcorn.
total cost for popcorn: 3($4.99)=$14.97
Each person got one candy bar: 3($3.50)=$10.50.
Finally, you add up the totals:
$30.75+$14.97+$10.50=$56.22
Answer:
$56.22
Step-by-step explanation:
$10.25 x 3 = $30.75
$4.99 x 3 = $14.97
$3.50 x 3 = $10.50
$30.75 + $14.97 + $10.50 = $56.22

y=-3x-8
Step-by-step explanation:
that's the answer
Answer:
y = - 3x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (0, - 8)
m = [tex]\frac{-8-1}{0+3}[/tex] = [tex]\frac{-9}{3}[/tex] = - 3
The line crosses the y- axis at (0, - 8 ) ⇒ c = - 8
y = - 3x - 8 ← equation of line

Answer:
wHaT?!?!!??!?!?!?!?!
Find the real solution(s) of the equation. Round your answer to two decimal places
when appropriate.
(x + 4) = -125
Answer:
-9
Step-by-step explanation:
Given the expression
(x+4)³ = -125
We are to find the value of x
Cube root both sides
³√(x+4)³ = ³√-125
x+4 = -5
Subtract 4 from both sides
x+4-4 = -5-4
x = -9
Hence the real solution to the equation is -9
