Step-by-step explanation:
since 105 + z is a straight line we know it equals 180 so we can use this equation
180 = 105 + z
simplify
75 = z
the since we know that all quadrilaterals equal 360 degrees we can add our two given number and z then subtract from 360:
102 + 85 + 75
= 262
now subtract
360 - 262
= 98
y = 98

Sum of the radius of the base and height of a cylinder is 21 cm and the curved surface area of the cylinder is 616 sq.cm,find the total surface area of the cylinder.
Please help me!
Answers
Given:
Sum of the radius of the base and height of a cylinder = 21 cm
Curved surface area of the cylinder = 616 sq.cm
To find:
The total surface area of the cylinder.
Solution:
Let r be the radius of the base and h be the height of the cylinder.
Sum of the radius of the base and height of a cylinder = 21 cm
[tex]r+h=21[/tex]
[tex]h=21-r[/tex] ...(i)
Curved surface area of the cylinder is
[tex]CSA=2\pi rh[/tex]
Curved surface area of the cylinder = 616 sq.cm
[tex]2\pi rh=616[/tex]
[tex]2(\dfrac{22}{7})r(21-r)=616[/tex]
[tex]44r(21-r)=616\times 7[/tex]
[tex]21r-r^2=\dfrac{616\times 7}{44}[/tex]
[tex]21r-r^2=14\times 7[/tex]
[tex]0=98-21r+r^2[/tex]
[tex]0=98-14r-7r+r^2[/tex]
[tex]0=14(7-r)-r(7-r)[/tex]
[tex]0=(7-r)(14-r)[/tex]
[tex]r=7,14[/tex]
Using (i), for r=7, h=14 and for r=14, h=7.
Total surface area of the cylinder is
[tex]A=2\pi r(r+h)[/tex]
For r=7 and h=14,
[tex]A=2(\dfrac{22}{7})(7)(7+14)[/tex]
[tex]A=44(21)[/tex]
[tex]A=924[/tex]
For r=14 and h=7,
[tex]A=2(\dfrac{22}{7})(14)(14+7)[/tex]
[tex]A=88(21)[/tex]
[tex]A=1848[/tex]
Therefore, the total surface area of the cylinder is either 924 sq.cm or 1848 sq. cm.

Work out the number of adults
Answers
Answer:
[tex]Adults = 510[/tex]
Step-by-step explanation:
Given
[tex]Children = \frac{3}{5}[/tex]
[tex]Girls:Boys = 2 : 7[/tex]
[tex]Girls = 170[/tex]
Required
Determine the number of adults
First, we need to calculate the number of children
[tex]Girls:Boys = 2 : 7[/tex]
Given that: [tex]Girls = 170[/tex]
Substitute 170 for Girls in [tex]Girls:Boys = 2 : 7[/tex]
[tex]170 : Boys = 2 : 7[/tex]
Convert to fraction
[tex]\frac{170}{Boys} = \frac{2}{7}[/tex]
Cross Multiply
[tex]Boys * 2 = 170 * 7[/tex]
Divide both sides by 2
[tex]Boys = \frac{170 * 7}{2}[/tex]
[tex]Boys = \frac{1190}{2}[/tex]
[tex]Boys = 595[/tex]
So, the number of children are:
[tex]Children = Boys + Girls[/tex]
[tex]Children = 595 + 170[/tex]
[tex]Children = 765[/tex]
Next, we calculate the number of people in the cinema.
[tex]Children = \frac{3}{5} * People[/tex]
Substitute 765 for Children
[tex]765 = \frac{3}{5} * People[/tex]
Make People the subject.
[tex]People = \frac{765 * 5}{3}[/tex]
[tex]People = \frac{3825}{3}[/tex]
[tex]People = 1275[/tex]
If 3/5 are children, then 2/5 are adults.
So:
[tex]Adults = \frac{2}{5} * 1275[/tex]
[tex]Adults = \frac{2* 1275}{5}[/tex]
[tex]Adults = \frac{2550}{5}[/tex]
[tex]Adults = 510[/tex]

Which equation represents a proportional relationship? Oy=2(x + 1) Oy=2 o y = 4x + 3 o y = 32x y
Answers
Answer:
y=32x shows a proportional relationship.
Step-by-step explanation:
We need to find an equation that shows the proportional relationship.
If x and y are proportional to each other, it will look like,
y = mx
Where
m is constant of proportionality
Out of 4 option, option (4) is y=32x, it shows the proportional relationship where the value of m is equal to 32.
The equation that represents a proportional relationship is y = 32x
What is a proportional relationship?A proportional relationship usually has the form:
y = kx
Where:
y = dependent variable k = constant of proportionality x = independent variableIn this equation: y = 32x

Step-by-step explanation:
This answer is my interpretation of what the question is asking, it could be wrong.
This question says, one has 2426 tablespoons, and 2 teaspoons of a substance. If one were divided that quantity in half, how much of that substance could they have. So essentially, all one needs to do is divided 2426 by 2, and divide 2 by 2.
2426 ÷ 2 = 1213
