Answer:
Number of ml of 40% sugar = x = 1000mL
Number of ml of 85% sugar used = y = 800mL
Step-by-step explanation:
Let the
Number of ml of 40% sugar = x
Number of ml of 85% sugar used = y
From the above question, our system of equations is given as:
x + y = 1800mL ....... Equation 1
x = 1800 - y
40% × x + 85% × y = 60% × 1800mL
0.4x + 0.85y = 1080.... Equation 2
We substitute 1800 - y for x in Equation 2
0.4(1800 - y) + 0.85y = 1080
720 - 0.4y + 0.85y = 1080
- 0.4y + 0.85y = 1080 - 720
0.45y = 360
y = 360/0.45
y = 800mL
Solving for x
x = 1800 - y
x = 1800 - 800
x = 1000mL
Therefore,
Number of ml of 40% sugar = x = 1000mL
Number of ml of 85% sugar used = y = 800mL

Answer:
B. 3(12 - x) = 6
Step-by-step explanation:
3(20 - 10) = 44
3(10) = 44
30 < 44
3(12 - 10) = 6
3(2) = 6
6 = 6
2(10) + 3 = 25
20 + 3 = 25
23 < 25
2(10) - 3 = 22
20 - 3 = 22
17 < 22

There are 4 cones with a height of 18 meters. The Radius of the Cones: Cone 1: 1 Cone 2: 2 Cone 3: 3 Cone 4: 4 What's the volume of each cone? Express your answer in terms of pi.
Answer:
6π
24π
54π
96π
Step-by-step explanation:
Cone 1:
Height, h= 18 meters
Radius, r = 1
Volume of cone 1 = πr²h/3
= (π * 1² * 18)/3
= (π * 1 * 18)/3
= 18π/3
= 6π
Cone 2:
Height, h= 18 meters
Radius, r = 2
Volume of cone 2 = πr²h/3
= (π * 2² * 18)/3
= (π * 4 * 18)/3
= 72π/3
= 24π
Cone 3:
Height, h= 18 meters
Radius, r = 3
Volume of cone 3 = πr²h/3
= (π * 3² * 18)/3
= (π * 9 * 18)/3
= 162π/3
= 54π
Cone 4:
Height, h= 18 meters
Radius, r = 4
Volume of cone 4 = πr²h/3
= (π * 4² * 18)/3
= (π * 16 * 18)/3
= 288π/3
= 96π

Answer:

Sum of interior angles is 180:
y = 180 - (42 + 31) = 107The law of sines:
x / sin 107 = 11 / sin 42x = 11 sin 107deg / sin 42deg x = 15.72#2
The law of cosines:
cos 76 = (6² + 17² - x² )/2(6)(17)204*0.24 = 325 - x²x² = 325 - 48.96x² = 276.04x = √276.04x = 16.61#3
Same as above:
2*9.4*10*cos 20 = (10² + 9.4² - x²)176.66 = 188.36 - x²x² = 188.36 - 176.66 x² = 11.7x = √11.7x = 3.42#4
Sum of interior angles is 180:
y = 180 - (52 + 94) = 34The law of sines:
x / sin 34 = 15 / sin 94x = 15 sin 34 / sin 94 x = 8.41The weight of the rectangle is 80
grams.
The weight of the triangle is
double the weight of the circle.
Determine the weight of the circle.
Answer:
6 2/3
Step-by-step explanation:
Rectangle has four sides. The total weight of the circle is 20 grams.
What is a rectangle?A rectangle is a 2D shape that has four sides, and the pair of opposite sides are equal and parallel to each other.
As it is given that the weight of the rectangle is 80 grams, and a rectangle is made up of two triangles. Therefore, the weight of each triangle can be written as,
[tex]\text{Weight of the reactangle} = \dfrac{\text{Total weight of the reactangle}}{\text{Number of Triangles}}[/tex]
[tex]\text{Weight of the reactangle} = \dfrac{80}{2} = 40\rm\ grams[/tex]
It is given that the total weight of the triangle is double the weight of the circle. therefore, the relationship can be written as,
[tex]\text{Weight of the triangle} = 2 \times \text{Weight of the circle}[/tex]
[tex]40= 2 \times \text{Weight of the circle}\\\\\text{Weight of the circle} = 20\rm\ grams[/tex]
Hence, the total weight of the circle is 20 grams.

Consider the function graphed below.
Which function does the graph represent?
Answer:
its c on edge 2021
Step-by-step explanation:
The function of graph is
f(x) = { x² , x < 1
1/3x+ 2/3 , x > 1
What is function?In mathematics, a function is an expression, rule, or law that establishes the relationship between an independent variable and a dependent variable. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.
For first part of graph we have the equation of parabola as
y = a (x- h)² + k
At origin, h= 6 and k= 0
y = ax²
and, Passing through the point (1, 1)
1 = 1 (a)
a= 1
So, the equation first is y= x².
Now, for second part using slope intercept form
y= mx+ b
As, Passing through (1, 1) and (4, 2)
(y- 1) = (2-1)/ (4-1) (x- 1)
y-1 = 1/3 (x-1)
y - 1 = 1/3 x - 1/3
y - 1/3 x = -1/3 + 1
y - 1/3x = 2/3
y= 1/3x + 2/3
So, the function of graph is
f(x) = { x² , x < 1
1/3x+ 2/3 , x > 1

write in standard form 5.2-0.5x=1.9y
Answer:
5.2 = 0.5x + 1.9y
Step-by-step explanation:
In this case "standard form" signifies an equation resembling Ax + By = C.
Adding 0.5x to both sides results in 5.2-0.5x + 0.5x = 1.9y + 0.5x, or
5.2 = 0.5x + 1.9y, which is in "standard form."

A certain island contains 540 cats and 675 dogs. What is the ratio of cats to dogs on this island?
Answer:
4 : 5
Step-by-step explanation:
every 4 cats there are 5 dogs
The ratio of cats to dogs is 4 : 5
The ratio of cats to dogs is:
Number of cats : Number of dogs
540 : 675
Now you take them down to their lowest terms by dividing both numbers by their highest common factor.
The highest common factor of 540 and 675 is 135 so divide both sides by 135:
540 / 135 : 675 / 135
4 : 5
The ratio of cats to dogs is therefore 4 : 5.
