Answer:
Fraction 8/20
Step-by-step explanation:
So only 12 people don't use sugar so if we were to put a fraction for people who don't put sugar then it would be.
12/20
The 20 stands about how many people their are and the 12 stands for how many people don't put sugar.
So now we are supposed ot do peope who put sugar so it would look like this
8/20
How I got the 8 is that I took the 20 people and subtrack it with the people who don't get sugar which is 8 and 8 people use sugar so theirs our answers.
8/20

What is the gradient of the blue line?
X
Answer:
1/4
Step-by-step explanation:
Using points (0 ; 1) and (4 ; 2)
m= y2-y1 / x2-x1
= 2-1 /4-0
= 1/4
The gradient of the blue line is, 1/4
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the blue line are (3, -3) and (3, -6).
Now,
Since, The equation of line passes through the points (4, 2) and (8, 3).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (3 - 2) / (8 - 4)
m = 1 / 4
m = 1/4
Thus, The gradient of the blue line is, 1/4

Did I do this right????
Answer:
x = -7, y = -3 yup you did it right!
Step-by-step explanation:
Solve the following system:
{-2 y + x = -1 | (equation 1)
8 y - 5 x = 11 | (equation 2)
Swap equation 1 with equation 2:
{-(5 x) + 8 y = 11 | (equation 1)
x - 2 y = -1 | (equation 2)
Add 1/5 × (equation 1) to equation 2:
{-(5 x) + 8 y = 11 | (equation 1)
0 x - (2 y)/5 = 6/5 | (equation 2)
Multiply equation 2 by 5/2:
{-(5 x) + 8 y = 11 | (equation 1)
0 x - y = 3 | (equation 2)
Multiply equation 2 by -1:
{-(5 x) + 8 y = 11 | (equation 1)
0 x + y = -3 | (equation 2)
Subtract 8 × (equation 2) from equation 1:
{-(5 x) + 0 y = 35 | (equation 1)
0 x + y = -3 | (equation 2)
Divide equation 1 by -5:
{x + 0 y = -7 | (equation 1)
0 x + y = -3 | (equation 2)

Answer:
side: 17 inchesaltitude: 6 inchesStep-by-step explanation:
The formula for the area of a triangle gives a relationship between area, height, and base length. The problem statement gives the area, and it gives another relation between height and base length. Using these two relations, you can solve for the dimensions of the triangle.
__
setupThe side to which the altitude is measured is called the "base" in the area formula. The altitude is called the "height." The relation between them given by the area formula is ...
A = 1/2bh
51 = 1/2bh . . . . . . using the given value for area
The other relation given by the problem statement is that the base is 1 less than 3 times the height:
b = 3h -1 . . . . . . . base is 1 less than 3 times altitude
__
solutionUsing this second equation to substitute for 'b' in the first equation, we have ...
51 = 1/2(3h -1)h
102 = 3h² -h . . . . multiply by 2, eliminate parentheses
3h² -h -102 = 0 . . . . . put in standard form
3h² -18h +17h -102 = 0 . . . . . prepare to factor
3h(h -6) +17(h -6) = 0 . . . . . factor pairs of terms
(3h +17)(h -6) = 0 . . . . . . . . finish factoring
Solutions are the values of h that make these factors zero:
3h +17 = 0 ⇒ h = -17/3
h -6 = 0 ⇒ h = 6
We know that dimensions in a geometry problem must be positive, so the solution here is h = 6. Then b = 3h -1 = 3(6) -1 = 17. The dimensions are all in inches.
The length of the side is 17 inches; the altitude to that side is 6 inches.

The three positive numbers whose sum is 27 will be 14, 1, and 12.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
Suppose the three positive numbers are x, y and z.
If the summation of numbers is 27.
⇒ x + y + z = 27 --- (1)
⇒ z = 27 - x - y
Suppose the square sum of the number be S.
∴ S = x² + y² + z²
⇒ S = x²+ y² + (27 - x - y)² --- (2)
We will optimize the function, partially differentiating it with respect to x and y, and setting dS/dx = 0 to get the minimum value of S.
2x + 2(27- x - y)(-1) = 0
2x - 54 + 2x + 2y = 0
4x + 2y - 54 = 0
y = 27 - 2x --- (3)
Differentiate partially with respect to y as
2y + 2(27 - x - y)(-1) = 0
2y - 54 + 2x + 2y = 0
4y + 2x - 54 = 0
x = 54 - 2y --- (4)
Substitute the value of y = 27 - 2x in the equation (4),
x = 12 - 2(27 - 2x)
x = 12 - 54 + 4x
4x - x = 54 - 12
3x = 42
⇒ x = 14
By substituting x = 14 in equation (3)
y =2(14) - 27
y = 28 - 27
⇒ y = 1
Substitute the values of x and y in equation (1),
14 + (1) + z = 27
z = -14+27-1
z= 12
Thus, the three positive numbers whose sum is 27 will be 14, 1, and 12.

Answer:
x = 26
Step-by-step explanation:
The length marked x is the hypotenuse of a right triangle with legs 10 and 24. The Pythagorean theorem can be used to find the value of x.
The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the legs:
x² = 10² +24²
x² = 100 +576 = 676 . . . . simplify
x = √676 . . . . . . . take the square root
x = 26
Answer:
The hypotenuse is 26 units
Step-by-step explanation:
Step 1: Determine the value of x
Pythagorean theorem: [tex]a^2 + b^2 = c^2[/tex]
[tex](24)^2+(10)^2=c^2[/tex]
[tex]576 + 100 = c^2[/tex]
[tex]676 = c^2[/tex]

The radius of a circle is 9 feet. What is the Area and the circumference of the circle?
Answer:
area is 254.34 circumference is 56.52
Step-by-step explanation:
To find the area you need to follow the formula r^2(pi)
so it would be 9x9x3.14 which is 254.34
to find circumference you need to find diameter which is double the radius (9x2) so the diameter is 18
To find circumference to need to do radius x pi
18x3.14 is 56.52
