Mary is painting pumpkins to earn money. She plans on selling each pumpkin for $7.50. She currently has $200 in her savings account. Is the amount of money in her bank account proportional to the number of pumpkin she sells?
Answer: No. It's not proportional
Step-by-step explanation:
The direct proportion in mathematics is expressed as:
y = kx
where
y = $200
k = constant
x = $7.50
We then solve for k
y = kx
200 = 7.50k
k = 200/7.50
k = 26.67
Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.
Madhu bought a washing machine for Rs 13,000. He then sold it for Rs 15,000. He also paid Rs 300 to arrange the delivery of the washing machine at the buyer's house.
How much profit did Madhu make by selling the washing machine?
cost price=1300
selling price=1500
1500_1300=2000
madhu use 300 from his profit so
2000_300=1700
answer=1700

(6) QP = QR therefore, triangle QPR is an isosceles triangle.
Since QPR is an isosceles triangle, the base angles are equal.
angle P + angle R + 80 = 180
2x + 80 = 180
2x = 100
x = 50.
That is just the measure of the base angle.
Now take triangle TSR.
Since R = 50, due to angle sum property, we can come up with this equation:
50 + 85 + x = 180
x = 180 - 135
x = 45 <- That's the answer.
(8) Take triangle PSQ, you get angle P = 70 degrees using the angle sum property and algebra.
Now take triangle PSR and you get angle P in the triangle as (180 - 100) / 2 = 40.
Since P = 70, and P in the smaller triangle is 40, 70 - 40 would be the answer.
x = 30 degrees <- That's the answer :D
The first floor of a house consists of a kitchen, playroom, and dining room. The areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2 . The combined area of these three rooms is 189 square feet. What is the value of one box on the tape diagram ?
Answer:
The value of one box in the tape diagram will be 21 square feet
Step-by-step explanation:
Here, we have the total ratio added as 4 + 3 + 2 = 9
So the area of one box on the tape diagram will be the combined area divided by the total square feet
Mathematically, that will be;
189 square feet/9 = 21

Need help quick!!!!! Ada and Steve spend a certain amount of money from their accounts each week at a pet shelter.
The table shows the relationship between the amount of money (y) remaining in Ada's account and the number of weeks (x):
Function 1:
Number of Weeks
(x) Amount Remaining (dollars)
(y)
1 40
2 36
3 32
4 28
The equation shows the relationship between the amount of money, y, remaining in Steve's account and the number of weeks, x:
Function 2:
y = −5x + 40
Which statement explains which function shows a greater rate of change? (1 point)
Function 1, because Ada spends $4 each week and Steve spends −$5 each week
Function 1, because Ada spends $12 each week and Steve spends $35 each week
Function 2, because Steve spends $5 each week and Ada spends $4 each week
Function 2, because Steve spends $40 each week and Ada spends $12 each week
Answer:
Function 2, because Steve spends $5 each week and Ada spends $4 each week
Step-by-step explanation:
Function 1 shows a rate of change of using two points
(x1, y1) = (40,1)
(x2,y2) = (36,2)
m = (y2-y1)/(x2-x1) = (36-40)/(2-1) = -4
The rate of change is decreasing or spending at $4 per week
Function 2 shows an equation y=mx+b; where m is the slope or the rate of change
m=-5
The rate of change is decreasing or spending at $5 per week
Answer: its C
Function 2, because Steve spends $5 each week and Ada spends $4 each week

Decrease 125 by 40% maths assignment
Answer:
75
Step-by-step explanation:
125 × 0.40 = 50
125 - 50 = 75
Decrease number by 40% of its value.
Percentage decrease = 40% × 125
New value
125 - Percentage decrease
125 - (40% × 125)
125 - 40% × 125
(1 - 40%) × 125
(100% - 40%) × 125
60% × 125
60 ÷ 100 × 125
60 × 125 ÷ 100
7,500 ÷ 100

Answer:
y - 2 = 3 (x - 4) - Point-Slope form.
y = 3x - 10 - Slope-intercept form.
Step-by-step explanation:
I will solve by using the formula:
y - y1 = m (x - x1)
Substitute:
y - 2 = 3 (x - 4)
This is the answer written in point-slope form.
I will put it into slope-intercept form.
Distribute:
y - 2 = 3x - 12
add 2 to both sides:
y = 3x - 10
Point (4 , 2) with a slope of 3 as an equation written in slope-intercept form looks like:
y = 3x - 10
The equation in point-slope form is y = 3x - 10 for the line that passes through the point at (4,2) with the given slope m=3.
What is the slope of the line?The slope of a line is defined as the angle of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
Given that line that passes through the point at (4,2)
Let the equation in point-slope form would be
⇒ y - y₁ = m(x -x₁ )
Here, slope m = 3, x₁ = 4 and y₁ = 2
Substitute the values in the equation, and we get
⇒ y - 2 = 3 (x - 4)
⇒ y - 2 = 3x - 12
Add 2 to both sides of the equation
⇒ y = 3x - 10
Hence, the equation in point-slope form is y = 3x - 10 for the line that passes through the point at (4,2) with the given slope m = 3.

Please guys help me :( A bell tower that is 60 yards tall casts a shadow 32 yards long. If a nearby windmill is
45 yards tall, how long will the windmill's shadow be?
Write your answer as a whole number or a decimal. Do not round.
Answer:
The shadow of the windmill will be 24 yards long
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ A bell tower that is 60 yards tall casts a shadow 32 yards long
∴ The tall = 60 yards and the shadow = 32 yards
∵ A windmill is 45 yards tall
∴ The tall = 45 yards
→ By using the ratio method
→ Tall : Shadow
→ 60 : 32
→ 45 : x
→ By using the cross multiplication
∵ x × 60 = 45 × 32
∴ 60x = 1440
→ Divide both sides by 60
∵ [tex]\frac{60x}{60}=\frac{1440}{60}[/tex]
∴ x = 24
∴ The shadow of the windmill will be 24 yards long

On the day a person is born, a deposit of $10,000 is made in a trust fund that pays 5% interest, compound quarterly. Find the balance on the person's 18th birthday.
Given:
Amount deposited on birth = $10,000.
Interest rate = 5% compound quarterly.
To find:
The balance on the person's 18th birthday.
Solution:
The formula for amount is
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.
Substitute P=10000, r=0.05, n=4, t=18 in the above formula.
[tex]A=10000\left(1+\dfrac{0.05}{4}\right)^{4(18)}[/tex]
[tex]A=10000\left(1+0.0125\right)^{72}[/tex]
[tex]A=10000\left(1.0125\right)^{72}[/tex]
[tex]A=24459.2026814[/tex]
[tex]A\approx 24459.20[/tex]
Therefore, the balance on the person's 18th birthday is $24459.20.

The amount of money left in Alma’s bank account is expressed by the linear equation y = -27x + 577, where x represents the number of weeks and y represents the amount of money left in her account. After how many weeks will Alma have $145 left in her account?
12 weeks
16 weeks
22 weeks
26 weeks
Answer: 16 weeks
Step-by-step explanation:
If y represents the amount of money left in her account, then left y be $145 in the equation and solve for x.
145 = -27x + 557
-557 -557
-432 = -27x

Answer:
[tex]\huge\boxed{\sf 126\° \ OR \ 145 \°}[/tex]
Step-by-step explanation:
m∠4 + m∠7 = 180 (Adjacent Angles of a parallelogram)
Given that m∠4 = x + 45, m∠7 = x² + 45
x + 45 + x² + 45 = 180
x² + x + 90 = 180
x² + x = 180 - 90
x² + x = 90
x² + x - 90 = 0
Using mid-term break formula
x² + 10x - 9x - 90 = 0
x(x+10) - 9(x+10) = 0
(x - 9)(x + 10) = 0
Either,
x-9 = 0 OR x+10 = 0
x = 9 OR x = -10
[tex]\rule[225]{225}{2}[/tex]
Now,
m < 7 = x² + 45
For x = 9
m < 7 = (9)² + 45
m < 7 = 81 + 45
m < 7 = 126°For x = -10
m < 7 = (-10)² + 45
m < 7 = 100 + 45
m < 7 = 145°[tex]\rule[225]{225}{2}[/tex]
