Answer:
l and k are both 70
Step-by-step explanation:
l and k are both the same angle.
130+90= 220
360-220=140
140/2=70
therefore l and k are both 70
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.
Constructed Response you have an economic decision to make. You have $50.00 to spend. Should you purchase sports equipment to use at home, a ticket to attend a professional sporting event, or sports memorabilia for your football collection ?
Answer:
Step-by-step explanation:
From a business standpoint, I think the smartest decision would be either the sports equipment or the memorabilia. Each has pros and cons so it depends on you. The sporting event would be the worst option as it is something that can most likely be viewed for free online. The sporting equipment will still hold monetary value and can be resold as well as providing you with other value if used properly such as being healthier and/or putting on muscle. The Sports Memorabilia would not provide real life value but may increase in monetary value and have a much higher resale value than the equipment.
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.
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 :])

Which sequence is an example of an arithmetic sequence
Answer:
Only the third sequence is arithmetic
Step-by-step explanation:
If the sequence has a common difference, then it is arithmetic. To find the common difference, substract a term from the next term.
First sequence:
10 - 20 = -10 5 - 10 = -5 The differences are not the same, so the sequence is NOT arithmetic
Second sequence:
-6 - (-3) = -3 -18 - (-6) = -12 The differences are not the same, so the sequence is NOT arithmetic
Third sequence:
10 - 5 = 5 15 - 10 = 5 20 - 15 = 5 The differences are the same, so the sequence is arithmetic
Fourth sequence:
10 - 5 = 5 20 - 10 = 10 The differences are not the same, so the sequence is NOT arithmetic

Solve the system by substitution
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

Total marks: 3
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.

Answer:
1 / We have the area of a rectangle ABCD = 8 x 16 = 128 ft²
2 / Find the area of an isosceles Δ DEF:
The base of the isosceles ΔDEF => DF = DC- FC = 16 -12 = 4 ft
So the area of Δ DEF = 1/2 (DF x EH) = 1/2 (4 x 6) = 12 ft²
3 / Area of the irregular shape = area ABCB + Area DEF = 128 + 12 = 140 ft²

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.

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).
