What is the surface area of the cone?
14 in²
43.96 in²
50.24 in²
56.52 in²
The surface area of the cone is 56.52 in².
What is Surface Area?An object's surface area is the total area that all of its surfaces occupy. Many 3D shapes in geometry have various surface areas, which are simply calculable using the formulas.
As per the given diagram:
slant height of the cone (l) = 7 inch
radius of the cone (r) = 2 inch
For the surface area of the cone:
= πr(l+r)
= (22/7) × 2 × (7 + 2)
= (396/7)
= 56.52 in²
Hence, the surface area of the cone is 56.52 in²

Yosune walked her dog 5 miles today and plans to walk her dog 2.5 miles everyday from now on. The total number of miles walked y can be represented by y=2.5x+5 where x is the number of days walkef
Answer:
The answer is below
Step-by-step explanation:
Yosune walked her dog 5 miles today and plans to walk her dog 2.5 miles every day from now on. The total number of miles walked y can be represented by y = 2.5x + 5, where x is the number days walked after today. a. State the x- and y-intercepts and then graph the equation. b. Interpret the x- and y-intercepts.
Solution:
The equation for a linear function is given by:
y = mx + b; where m is the slope of the function and b is the y intercept.
Given the equation y = 2.5x + 5, the y and x intercept can be found by substituting x = 0 and y = 0. Hence:
a) x intercept is the value of x when y = 0. Therefore:
0 = 2.5x + 5
2.5x = -5
x = -2
y intercept is the value of y when x = 0. Therefore:
y = 2.5(0) + 5
y = 5
b) The x-intercept is at the point (–2, 0). But there cannot be a negative number of days walked, hence the x intercept does not apply in this situation.
The y intercept is at the point (0, 5). This means that Yosune has initially walked her dog 5 miles.

Find the missing side lengths. All answers should be in fully simplified form.
a=?
b?
Answer:
a=8 b=6
Step-by-step explanation:
Using the Pythagorean theorem, a^2+b^2=c^2, and in this case, a^2+b^2=10^2 = 100
so a^2+b^2=100
8^2+6^2=100
64+36=100 ✔
and since A is longer than B, a=8, b=6
Answer: a= [tex]5\sqrt{3}[/tex] b= 5

Pls help! I dont know what to put im horrible at patterns
Answer:
divide by 4, 12, 21
Step-by-step explanation:
first, look at 20, and 5. How do you get there?
well, there are 2 possible ways.
20/4=5, or 20-15=5
we take it into the next pattern to get
44/4=11, and 44-15=29.
so now we know that the rule is to divide by 4
____________________________________________
36/4 = 12
84/4=21
Answer:
1. 36 / 4 = 9
2. 84 / 4 = 21
Rule: The input divided by 4. (I / 4 = O)
Step by Step explanation:
Look at the first input and output, what do you see? Well, 5 is a multiple of 20, but if 5 is the output, this means that instead of multiplication we're doing division. How many times does 5 go into 20? 4 times, so that's our rule, I / 4 = O. If we use this rule for the rest of the questions, you get the answer.

Question:
The area of a rectangular computer chip is 112a^3b^2 square microns. Write a simplified expression that represents the length, if the width is 8ab
Answer:
[tex]Length = 14a^2b[/tex]
Step-by-step explanation:
Given
[tex]Area = 112a^3b^2[/tex]
[tex]Width = 8ab[/tex]
Required
Determine the height
Area is calculated as:
[tex]Area = Length * Width[/tex]
Make Length the subject
[tex]Length = \frac{Area}{Width}[/tex]
[tex]Length = \frac{112a^3b^2}{8ab}[/tex]
[tex]Length = \frac{14a^3b^2}{ab}[/tex]
Apply law of indices
[tex]Length = 14a^{3-1}b^{2-1}[/tex]
[tex]Length = 14a^2b[/tex]

The oblique prism has a rectangular base with a width of 10 units and a length of 13 units. An oblique prism with a rectangular base is shown. The rectangular base has a width of 10 units and a length of 13 units. The distance between the top and the bottom base is 17 units. The top base extends 8 units to the right of the bottom base. The top base extends 8 units to the right of the bottom base. What is the volume of the prism? 1,040 cubic units 1,360 cubic units 1,950 cubic units 2,210 cubic units
Answer:
1,950 cubic units
Step-by-step explanation:
The computation of the volume of the prism is shown below:
Area of the rectangle = length × breadth
= 10 units × 13 units
= 130 units^2
Now the volume of the prism is
= Base × height
= 130 units × √(17^2 - 8^2)
= 130 units × 15 units
= 1,950 cubic units
Answer:
1,950 Cubic Units
Step-by-step explanation:

What is the total surface area??
Answer:
790 units^2
Step-by-step explanation:
Take the area of each side and add them all up. Remember each side is there twice.
Formula: SA = 2(15*5 + 15*16 + 5*16)
SA = 2(75 + 240 + 80)
SA = 2(395)
SA = 790

What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = 4 + 2 ( b + 3 )
On simplifying the equation , we get
A = 4 + 2b + 6
A = 2b + 10
Hence , the expression is A = 2b + 10

Mr. Gibbs bought number of shirts for the new members of his band. The cost for number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. How many shirts did Mr. Gibbs buy?
Answer:
Number of shirts= 6
Step-by-step explanation:
Giving the following information:
The cost for several shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25.
First, we need to calculate the net total price paid for the shirts:
Net total cost= 77.49 - 3.99= $73.5
Now, the number of shirts bought:
Number of shirts= 73.5 / 12.25
Number of shirts= 6
