2 cm
Step-by-step explanation:
h = 14 cm
Curved surface area of a right circular cylinder = 88 cm²
2πrh = 88
[tex]2 * \frac{22}{7}*r*14=88\\\\r = \frac{88*7}{2*22*14}\\\\ r =1 \\\\r = 1 cm[/tex]
Diameter = 2 * r = 2 * 1 = 2 cm

Select the table representing a linear function. (Graph them if necessary)
Answer:
B
Step-by-step explanation:
There are a couple of ways you can go about solving this. The first is plotting all of the points and seeing which one makes a straight line. This is a little bit more time consuming but is great if you blank out and forget how to solve it. The faster way to do it is to see which function is decreasing/increase a constant amount between equal intervals. A increases but by a different amount each time. B decreases by 2 each time. C decreases at different intervals each time. And D does not consistently increase or decrease.

Answer:
5,040 ways
Step-by-step explanation:
Here, we want to find the number of ways they can sit
The total
number here is 3 + 4 = 7
The first person has 7 choices, next has 6 choices and so on
So the total
number of ways will
be :
7! = 5,040 ways
Are the ratios 5:3 and 6:4 equivalent?
yes
no
Answer:
nope
Step-by-step explanation:
The given ratios 5:3 and 6:4 are not equivalent.
What are Equivalent ratios?Equivalent ratios are the ratios that are the same when we compare them. Example 1/2 and 2/4 are equivalent ratios.
Two or more ratios can be compared with each other to check whether they are equivalent or not.
The given two ratios are 5:3 and 6:4
We can write them as 5/3 and 6/4
Let us apply subtraction, if we get 0 then these are equivalent.
6/4-5/3
The LCM of 4 and 3 is 12
=(18-20)/12
The value of 18-20 is -2
=-2/12
We have to divide 2 by 12 we get -1/6.
=-1/6 not equal to 0

The time (t) required to finish a certain job is inversely
proportional to the number of persons (p) on the job. If 10
persons can finish the job in 6 hours, how long will it take
for 30 persons to finish the job?
18 hours
Step-by-step explanation:
6/10=0.6 hours (one person takes 0.6 hour)
0.6×30=18 hours
or another way 10 is 1/3 of 30. so
6:1/3=18

A new arrow needs to be painted on the road to direct traffic.
What shapes can the figure be broken into?
What is the area of the arrow?
I
7 ft
1 ft
2 ft
11 ft
Answer:
The arrow can be broken into a rectangle and a triangle.
And the area of the arrow is 22 ft^2
Step-by-step explanation:
Area of the rectangle:
length • width = 7 • 2 = 14 ft^2
Area of the triangle:
(base • height) / 2
You must add 1 + 2 + 1 in order to get the base which is 4
And to get the height, you must do 11 - 7 = 4 (height)
(4 • 4) / 2 = 8 ft^2
Add both areas together to get the area of the arrow:
14 ft^2 + 8 ft^2 = 22 ft^2

if £2000 is placed into a bank account that pays 3% compound interest per year how much will be in account after 2 years?
Answer:
£2121.80
Step-by-step explanation:
Year 1 -> 2000 + (3% of 2000) = 2000 + (60) = 2060
Year 2 -> 2060 + (3% of 2060) = 2060 + (61.80) = 2121.80
The length and breadth of rectangular field are 240m and 200m respectively. Find the cost of digging the field at Rs 10 per m^2
Answer:
Please check the explanation.
Step-by-step explanation:
Given
The length of rectangular field = l = 240mThe breadth of rectangular field = w = 200mWe can determine the area of the rectangular field using the equation
[tex]A=wl[/tex]
where
[tex]l[/tex] is the length [tex]w[/tex] is the widthsubstituting l = 240m, and w = 200m in the formula
[tex]A=wl[/tex]
A = 240 × 200
A = 48000 m²
Given that the cost of digging the field at Rs 10 per m².
Thus,
The cost of digging the field of the area 48000 m² = 10 × 48000
= 480000 Rs
Therefore, the total cost of digging = 480000 Rs
two brothers, richard and andrew share a sum £30 in the ratio 3:7 how much does each brother get?
Answer:
Richard gets: £9
Andrew gets: £21
Step-by-step explanation:
To get the value of 1 part we have to add the total number of parts (3+7) and then divide them by the sum (30) 30/10 = 3 so we know 1 part is £3
Thus Richard gets: £3*3 = £9
And Andrew gets: £3*7 = £21

Answer:
The equation is;
y = -2x + 1
the answer belonging in the green question mark is -2
Step-by-step explanation:
We start by getting the slope
The slope can be obtained by selecting any two points and applying the slope formula
let us select the points;
(1,-1) and (3,-5)
the slope formula is;
m = (y2-y1)/(x2-x1)
m = (-5-(-1)/(3-1)
m = (-5+1)/2 = -4/2 = -2
The y intercept is the value of y when x = 0
As it can be seen, y = 1 when x = 0
so the equation of the relation is;
y = -2x + 1
