Answer:
No Mason is not correct you would use fractions and find a common denominator such as 12 and 2/3 would be 8/12 and 3/4 would be 9/12 therefore the two ratios are not equivelent
No, the statement is not correct.
What is ratio?Ratio is the comparison of two quantities which is obtained by dividing the first quantity by the other. If a and b are two quantities of the same kind and with the same units, such that b is not equal to 0, then the quotient a/b is called the ratio between a and b. Ratios are expressed using the symbol of the colon (:). This means that ratio a/b has no unit and it can be written as a : b
The example given here is not relevant.
This is because if 2:3 is added by 1/1
gives 3/4 or 3:4
but 3:4 cannot be more simplified.
So, let us make the equivalent denominator for both
2/3*4*4= 8/12
3/4*3/3=9/12
So, 2:3 ≠3:4

How much profit did Madhu make by selling the washing machine?
cost price=1300
selling price=1500
1500_1300=2000

[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]

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

(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
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.

Write an equation in point-slope form for the line that passes through the point with the given slope. point: (4,2) and m=3 *
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.

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

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
