Find he lateral and total surface area of each cone. Round to the nearest tenth
Answers
Answer:
a) Lateral surface area = 1225.2 m²
b) Total surface area = 1756.2 m²
Step-by-step explanation:
We are to find the Lateral and Total surface area of the cone in the diagram
Slant height = l = 30m
Diameter = 26 m
Radius = Diameter /2 = 26m/2 = 13m
a) The Lateral surface area of a cone when given the slant height is calculated as:
πr × l
= π × 13 × 30
= π × 13 × 43
= 1225.2211349 m²
Approximately = 1225.2 m²
b) The Total Surface area of the cone when given the slant height is calculated as:
πr( r + l)
= π × 13 × (13 + 30)
= π × 13 × 43
= 1756.1502934 m²
Approximately = 1756.2 m²

(24,4,84)
Step-by-step explanation:
Since they restricted our domains to certain x values, we can find the range by plugging in the x values to find it y value or output.
[tex]f( - 2) = 5( { - 2}^{2} ) + 4[/tex]
[tex]5(4) + 4 = 24[/tex]
[tex]f(0) = - 5( {0}^{2} ) + 4 = 4[/tex]
[tex]5(4) {}^{2} + 4 = 84[/tex]
So our range is (24,4,84)
Answer:
f(x)=5x²+4
f(-2)=5×(-2)²+4
5×4+424f(0)=5(0)²+4
0+44f(4)=5×(4)²+4
5×16+484so the range of function{-2,0,4}is{24,4,85}

If we can show
then EH || FG
Answers
Answer:
D
Step-by-step explanation:
The answer is D because A and B is an alternate interior angle meaning they don't have to be parallel lines in order to show that they are the same angles. C is incorrect.
E is incorrect because perpendicular lines mean that they have to be 90 degrees angle but the one that is shown is diagonal instead.
If we can show ∠4 ≅ ∠8 then EH || FG. [option A]
What are parallel lines?Two lines are said to be parallel if they do not meet each or intersect each other and have same slope.
Given is a quadrilateral EFGH, we need to determine a reason that can show EH || FG.
So, we know if two alternate angles between two lines are equal then the lines will be parallel by converse of alternate angles theorem.
Here, ∠4 and ∠8 are alternate angles, so if we show that ∠4 ≅ ∠8 then we can conclude that EH || FG.
Hence the correct option is A.

Answers
Answer:
Step-by-step explanation:
From the dot plot of start of school year,
Maximum value of the miles run = 10
Minimum value of the miles run = 5
Range of the data set = 10 - 5
= 5 miles
From the dot plot of End of school year,
Maximum value of the miles run = 10
Minimum value of the miles run = 6
Range of the data set = 10 - 6
= 4 miles
The range at the start of the year was 5 miles and the range at the end of the year was 4 miles.

A cellular phone is in the shape of rectangular prism. The height of the phone is 6 millimeters, and the width is 50 millimeters. The volume is 22,500 cubic millimeters. What is the length of the cellular phone?
Answers
Answer: 75ml
Step-by-step explanation:
The volume of a rectangular prism is:
= Length × width × height
where,
Volume = 22500ml³
Length = Unknown
Width = 50ml
Height = 6ml
We then slot the values into the formula.
Volume = Length × width × height
22500 = Length × 50 × 6
22500 = Length × 300
Length = 22500/300
Length = 75ml
The length of the cellular phone is 75ml.

6x - 5y = 11
y = 7x + 21
Answers
Answer:
x= -4, y= -7
Step-by-step explanation:
First, label the 2 equations.
6x -5y= 11 -----(1)
y= 7x +21 -----(2)
Substitute (2) into (1) so that the first equation is only written in terms of x.
6x -5(7x +21)= 11
6x -5(7x) -5(21)= 11 (Expand)
6x -35x -105= 11
-29x= 11 +105 (Simplify, +105 on both sides)
-29x= 116
x= 116 ÷(-29)
x= -4
Substitute x= -4 into (2):
y= 7(-4) +21
y= -28 +21
y= -7

what percent of 25$ is 5$ no links
Answers
Answer:
20%
Step-by-step explanation:
5 20% = 100%
Answer:
20% is 5$.
Step-by-step explanation:
Ok - these always need a bit of a read to make sure we're answering the right thing.
"What percent..." asks us for a percentage. Ok - good.
"...of 25..." asks us to take the number (25) and multiply it by the percentage we're going to find.
"...is 5" tells us what the answer we're looking for is. So we have:
25 × P = 5
- 25 times some percentage equals 5.
We can treat P as a variable and so can divide both sides by 25:
p = 5/25 = 1/5 = 0.2 = 20%.
