Answer:
A. 48 Km.
B. 62.5 miles.
Step-by-step explanation:
From the diagram given above, the following data were obtained:
50 miles = 80 Km
A. Converting 30 miles to kilometres.
50 miles = 80 Km
Therefore,
30 miles = 30 miles × 80 Km / 50 miles
30 miles = 48 Km
Thus, 30 miles is equivalent to 48 Km.
B. Converting 100 km to miles.
80 Km = 50 miles
Therefore,
100 Km = 100 Km × 50 miles / 80 Km
100 Km = 62.5 miles
Thus, 100 Km is equivalent to 62.5 miles.

10x=y
2x+y=-24
Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y
Water flows through a pipe at a rate of 89 quarts per hour. Express this rate of flow
in cubic meters per month. Round your answer to the nearest tenth.
Answer:
60.6 on delta math
Step-by-step explanation:
The rate of the flow will be 1.12 x 10⁻⁴ cubic meters per meter.
What is the rate of flow?The rate of the flow of the fluid is defined as the volume of the fluid through a confined space or cross-section in a unit of time. The unit of the rate of flow is gallons per minute or cubic meter per minute.
Given that water flows through a pipe at a rate of 89 quarts per hour the value of the rate of flow in cubic meters per month will be calculated as below:-
1 quartz = ( 1 / 1056.688) cubic meters
1 quartz = ( 89 / 1056.688)
1 quartz = 0.08 cubic meters
1 quartz per hour = 0.08 / ( 24 x 30) cubic meters per month
1 quartz per hour =1.12 x 10⁻⁴ cubic meters per month
Therefore, the rate of the flow will be 1.12 x 10⁻⁴ cubic meters per meter.

2. If 1/2 of a gallon of paint covers 1/8 of a wall, how much paint is needed to cover the entire wall?
A) 8 2/3 gallons
B) 8 1/3 gallons
C) 3 gallons
D) 2 gallons
Please help !
Answer: 4 gallons.
Step-by-step explanation:
With this equation, we can use the ratio 1/2 : 1/8. For every 1/2 gallon of paint, 1/8 of a wall is painted.
If 1/2 gallons covers 1/8 of a wall, then we need 8 of the 1/2 gallons to cover the whole wall. We canrepresent this by multiplying 8 and 1/2.
8 x 1/2 = 4.
Because of this, 4 gallons of paint are needed to cover he entire wall.
(Quick note: I don't know why, but the answer choices seem kind of weird. But the answer is 4 :])

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 – 160x + 300. The variable x is the number of televisions sold.
If 150 televisions are sold, what is the profit?
$2,700
$6,000
$50,700
$51,300
Answer: $50,700 is the profit
If 150 televisions are sold, the profit is $50,700.
What is profit?
Profit is the total revenue less the total cost.
Profit = total revenue - total cost
What is profit?Profit = (3x^2 + 180x) - (3x2 – 160x + 300)
Profit = (3 x 150^2 + 180 x 150) - (3 x 150^2 - 160x 150 + 300)
27,000 + 24,000 - 300
Profit = $50,700

Fiona was thinking of a number. Fiona divides by 8, then adds 11 to get an answer of 7. What was the original number?
Answer:
-32
Step-by-step explanation:
Do the opposite of everything to fin the number:
7 - 11 = -4
-4 x 8 = -32
Check to see if it's true:
-32/8 = -4
-4 + 11 = 7
So the original number was -32, because when you divide it by 8 then add 11 it equals 7.
In order to solve the equation below, what would be a valid first step?
4(x+8) =34−2x
A. Simply x + 8 to 8x.
B. Distribute the 4.
C. Subtract x from both sides.
D. Subtract 8 from both sides.

What is the equation for an arithmetic sequence with a first term of 5 and a second term of 2? (5 points) an = 5 − 2(n − 1) an = 5 + 2(n − 1) an = 5 − 3(n − 1) an = 5 + 3(n − 1)
Answer:
an = 5 − 3(n − 1)
Step-by-step explanation:
First term,a = 5
Second term = 2
Common difference,d = 2 - 5 = -3
nth term = a + d(n - 1)
= 5 -3(n - 1)
Check
When n = 2
2nd term = 5 - 3(2 - 1)
= 5 - 3(1)
=5 - 3
= 2
2nd term = 2

Answer is 4/25
Step-by-step explanation:
0.16*100 = 16 which would allow us to say 16/100
now you can divide 16 and 100 by 4 which would be
16/4 = 4 and 100/4= 25
therefore the answer is 4/25

Solve the system
9x^2 + 4(y - 2)^2 = 36
x^2 = 2y
Answer: y = 2 and x = 2
Step-by-step explanation:
[tex]9x^2+4(y-2)^2=36\\x^2=2y[/tex]
First, get the entire thing in terms of y, because you cant solve for two variables at the same time. They gave us the fact that x^2 = 2y
[tex]9(2y)+4(y-2)^2=36\\18y+4(y^2-4y+4)=36\\18y+4y^2-16y+16=36\\4y^2+2y-20=0[/tex]
What two numbers multiply to equal -80 but add to equal 2? That is +10 and -8.
[tex]4y^2+2y-20=0\\(4y^2-8y)+(10y-20)=0\\4y(y-2)+10(y-2=0)\\(4y+10)(y-2)=0\\y=-5/2\\y=2[/tex]
Now solve for x by plugging in y to the easier equation
[tex]x^2=2(-5/2)\\x\neq \sqrt{-5}[/tex]
If I didn't make a mistake, this should be the only answer. In the case of y = -5/2, you would get an imaginary x-value. Therefore y cannot equal -5/2
[tex]x^2=2(2)\\x=2[/tex]
The solution of the expression are,
x = 2.28 , y = 2.62
Or, x = 3.9i , y = - 7.62
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The system of equations are,
9x² + 4 (y - 2)² = 36 .. (i)
x² = 2y .. (ii)
Substitute the value of x² from (ii) in (i);
9x² + 4 (y - 2)² = 36
9 × 2y + 4 (y - 2)² = 36
18y + 4 (y - 2)² = 36
9y + 2 (y - 2)² = 18
9y + 2 (y² + 4 - 2y) = 18
9y + 2y² + 8 - 4y = 18
2y² + 5y + 8 - 18 = 0
2y² + 5y - 10 = 0
y = - 5 ± √5² - 4×2×- 10 / 2×2
y = - 5 ± √ 25 + 80 / 2
y = - 5 ± √ 105 / 2
y = - 5 ± 10.24 / 2
y = - 5 + 10.24 / 2
y = 5.24/2
y = 2.62
y = - 5 - 10.24 / 2
y = - 15.24 / 2
y = - 7.62
From (ii);
x² = 2y
x² = 2 × 2.62
x² = 5.24
x = 2.28
x² = 2y
x² = 2 × - 7.62
x² = - 15.24
x = 3.9i
Thus, The solution of the expression are,
x = 2.28 , y = 2.62
Or, x = 3.9i , y = - 7.62

How do you find the vertex
Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).

Step-by-step explanation:
On each coordinate plane, the parent function f(x) = |x| is represented by a dashed line and a translation is represented by a solid line. Which graph represents the translation g(x) = |x + 2| as a solid line? Why is it C???
The adding a value to x shifts the graph that many places to the left.
In g(x) you are adding 2 to x, so the graph moves 2 units to the left.

Ivan and tanya share £150 in the ratio 4 : 1 work out how much more ivan gets compared to tanya.
Answer:
Ivan receives £120 more than Tanya.
Step-by-step explanation:
Total Money = £ 150
Ratio = 4:1
This means that Ivan gets 4x of £150 and Tanya gets 1x of £150.
Ivan's money = 4x
Tanya's money = 1x
Now, we know that total money is equal to the sum of Ivan's & Tanya's money.
Total money = Ivan's money + Tanya's money
£ 150 = 4x + 1x
£ 150 = 5x
150/5 = x
30 = x.
We have found the value of x, now we can substitute 30 in the place of x and find the money Ivan and Tanya get.
Ivan = 4x = 4×30 = £120.
Tanya = 1x = 1×3 = £30.
So, Ivan receives more money. But how much more? We can solve that by subtracting Tanya's money from the total amount.
Total amount - Tanya's money = 150 - 30 = £120.
So, Ivan receives £120 more than Tanya.
