A cake recipe contains sugar and flour in the ratio 3 : 2.
How much of each ingredient is needed to make 600 gram of such a cake?
Answer:
360 g of sugar and 240 g of flour
Step-by-step explanation:
add the parts of the ratio, 3 + 2 = 5 parts
Divide the total by 5 to find the value of one part of the ratio.
600 g ÷ 5 = 120 g , thus
3 parts = 3 × 120 g = 360 g ← amount of sugar required
2 parts = 2 × 120 g = 240 g ← amount of flour required
Answer:
360 grams of sugar and 240 grams of flour
Step-by-step explanation:
First, find the sum of the parts of the ratio: 3 + 2 = 5
Divide the total amount (600) by the amount of parts:
600/5 = 120
Now multiply 120 by the amount of each part of the ratio:
210 * 3 = 360
360 * 2 = 240
360 grams of sugar and 240 grams of flour are needed to make 600 grams of a cake.

What is the length of segment MO?
PHOTO ABOVE
I need to pass!!!!!
Pls try!!!
Answer: 13
Step-by-step explanation: In the picture, you have angle H congruent to angle N, Side MN congruent to side GH, and angle G congruent to angle M. That means that these two triangles are congruent by ASA. Therefore by CPCTC, side GI is congruent to side MO, which means that MO is 13.
The value of y varies directly with the value of x. If x = 8 then y = 320. What is the value
of x when y = 52?
Answer:
1.3
Step-by-step explanation:
I believe this is correct because if you divided 320 by 52 you get 6.15384615385 (or just 6.1) and since we did it to the Y operation we do it to the X operation and x, aka 8, divided by 6.1 equals 1.3.

Translate this sentence into an equation 20 less than Jenny's score is 66?
Answer:
x-20=66
Step-by-step explanation:
Jenny's score can be written as a variable x. 20 less than x is x-20. The answer is 66, so that will be on the other side of the equation. The equation is written as: x-20=66.

m is the midpoint of segment AB. if M (-1,2) and A(-9,6) find the cooridinates of the other endpoints.
Answer:
B(7 , -2)
Step-by-step explanation:
A(-9 , 6)
Midpoint = (-1 , 2 )
[tex]Midpoint = (\frac{x_{1}+x_{2}}{2} , \frac{y_{1}+y_{2}}{2}) = (-1 , 2)\\[/tex]
[tex](\frac{-9+x_{2}}{2},\frac{6+y_{2}}{2}) = (-1 , 2)\\[/tex]
Compare the x co ordinates and y co ordinates,
[tex]\frac{-9+x_{2}}{2}= - 1[/tex] & [tex]\frac{6+y_{2}}{2}=2[/tex]
-9 + x₂ = -1*2 & 6 + y₂ = 2*2
-9 + x₂ = -2 & 6 + y₂ = 4
x₂ = -2 +9 & y₂ = 4 - 6
x₂ = 7 & y₂ = -2
B(7 , -2)

A home improvement store advertises 60 square feet of flooring for $287.00, which includes an $80.00 installation fee. Write an equation to represent the cost of one square foot of flooring
Given :
A home improvement store advertises 60 square feet of flooring for $287.00, which includes an $80.00 installation fee.
To Find :
Write an equation to represent the cost of one square foot of flooring.
Solution :
Fee of one square feet, p = $287/60 = $4.783 .
So, slope of equation will be 4.783 .
Price of installation is $80 dollar.
Therefore, equation to represent the cost of one square foot of flooring is :
C = 4.783n + 80
Here, C is total cost and n is number of square feet.
Hence, this is the required solution.

Solve this equation: 12−3(3x−5)=12(2x+1)
Answer:
x = -3/11
Step-by-step explanation:
First, distribute the -3 and 12 within the parenthesis
12 - 9x + 15 = 24x + 12
Now, combine like terms
3 - 9x = 24x + 12
Subtract 24x from both sides of the equation
3 - 33x = 12
Subtract 3 from both sides of the equation
- 33x = 9
Divide both sides by -33
x = -9/33
-9/33 can be simplified to -3/11, so the answer is
x = -3/11

What is the slope of the line that passes through these two points (0, -2) and (3, -4)?
Answer:
2
Step-by-step explanation:
Use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\frac{-4-(-2)}{3-0}[/tex] = [tex]\frac{6}{3}[/tex] = 2
The slope of the line will be "[tex]-\frac{2}{3}[/tex]".
The given points are:
[tex](x_1, y_1) = (0, -2)[/tex]
[tex](x_2, y_2) = (3, -4)[/tex]
As we know,
→ The slope of the line:
= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
By substituting the values, we get
= [tex]\frac{-4-(-2)}{3-0}[/tex]
= [tex]\frac{-4+2}{3}[/tex]
= [tex]-\frac{2}{3}[/tex]

All right triangles follow the Pythagorean theorem [tex]a^2+b^2=c^2[/tex] where the squares of the two shorter sides of the right angle triangle is equivalent to the square of the longest side.
Squares of the two shorter sides:
[tex]9^{2}+15^{2}=306[/tex]
Square of the longer side:
[tex]17^{2}=289[/tex]
∵ [tex]306\neq 289[/tex], ∴ the triangle is not a right angle triangle.
