What is the lateral surface area of a cone that has a slant height 17 inches and a diameter of 13 inches? 107.5

Answers

Answer 1

Answer:

c.s.a of cone = pie r^2 + pie r l

radius = diameter/2 = 13/2

slant height (l) = 17

pie (13/2)^2 + pie 13/2 * 17

3.14 * 169/4 * 3.14 * 13/2 * 17

368246/8

= 46030

can the side lengths
form a triangle ?
​

Answers

Answer: No

Step-by-step explanation:

Because 4^2=16

5^2=25

25+16=41

41 squared =6.4031.....

6.4031 does not = 20

Answer: No, a triangle is not possible

The two smaller sides add to 4+5 = 9 which is not larger than 20. For a triangle to be possible, we need to be able to add 2 sides to make them longer than the third side. This is an application of the triangle inequality theorem.

Jada has a 12 gallon gas tank and her gauge indicates that it is 3/4 full. How many gallons of gas does Jane have?

Answers

Answer: 9

Count on to find out how much 3/4 of 12 is.

3, 6, 9.

9 is 3/4 of the number 12.

3/4 of 12 = 9.

The answer to the question is 9.

Hope this helps!

A total of 9 gallons of gas jane have in their gas tank.

What are the ratio and proportion?

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b, will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Given that,

The capacity of a gas tank = 12 gallons.

Amount of gas present in has = 3/4 of capacity = (3/4)12.

The amount of gas present in has = 9 gallons.

Hence there will be a total of 9 gallons of gas available.

What subtraction sentence does this show? A. 4.3 - (-0.9) = 5.2 B. 4.3 - 0.9 = 5.2 C. -4.3 - 0.9 = 5.2

Answers

A is correct. Because two negatives equal positive, so 4.3-(-0.9)=4.3+0.9=5.2

Step-by-step explanation:

as two negative are equa positive same as A is correct

therefore

4.3-(-0.9)=4.3+0.9=5.2

56.7+23.44 useing front-end to estimate the sum

Answers

Answer:

Step-by-step explanation:

To estimate the sum of 56.7 and 23.44 using the front-end method, you can round each number to the nearest whole number and then add them together. This will give you an estimate of the sum that is close to the actual result.

Using this method, you would round 56.7 to 57 and 23.44 to 23, and then add them together to get an estimate of 80. This is a reasonable estimate of the sum of 56.7 and 23.44, which is actually 80.14.

Note that this method is not as accurate as using a calculator or performing the exact calculation, but it can be a useful tool for quickly estimating the sum of two numbers.

Answer:80

Step-by-step explanation: 56.7 when rounded is 57 and 23.44 rounded is 23 so 57+23 is 80

A swimming pool is 22 feet long and 18 feet wide. How many feet of fencing are needed to enclose the pool

Answers

Answer:

80 feet

Step-by-step explanation:

length of pool = 22    ,  width of pool = 18

feet required for fencing the pool = 2 (l +b)

= 2 ( 22+18)

=2*40

=80feet

Answer:

Step-by-step explanation:

The pool is a rectangle as length and breadth are different.

Since they are asking about fencing you need to find the perimeter.

Length=22feet

Breadth=18feet

Perimeter of a rectangle = 2(l+b)

= 2 × 22 + 2×18

=44+36

=80 feet

Extra Points! Please Help!And Explain too. (Or will be deleted)

Answers

Step-by-step explanation:

The lateral surface area is the area of the sides, not including the top and bottom.

Assuming the 3×6 rectangles are the top and bottom, the lateral surface area is:

LA = 2×3 + 2×3 + 2×6 + 2×6

LA = 6 + 6 + 12 + 12

LA = 36

The total surface area is the lateral surface area plus the area of the top and bottom.

SA = 36 + 3×6 + 3×6

SA = 36 + 18 + 18

SA = 72

SA is equal to 72!!!!

Answers

Answer:

Part A

x is 46°

Part B

Alternate angles are angles that are in relatively opposite locations relative to a transversal

Step-by-step explanation:

Part A

∠DRP  = 110° (Given)

∠QPA = 64° (Given)

∠QPR =

Given that AB is parallel to CD, we have;

∠DRP is congruent to ∠APR (Alternate angles to a transversal RP of parallel lines AB and CD)

Therefore, ∠APR = 115°

∠APR = ∠QPA + ∠QPR (Angle addition postulate)

∴ 115° = 64° +  ∠QPR

∠QPR = 110° - 64° = 46°

x = 46°

Part B.

Given that AB is parallel to CD, the lines common (that intersects) both lines are the transversal lines

The angles formed between the parallel lines and the transversal lines have special relationships based on their position with respect to each other

In the question, the angle 110° given between CD and the transversal RP, is found to at an alternate position to the angle ∠APR between the same transversal RP and AB and given that alternate angles are always equal, angle ∠APR is therefore also equal to 110°.

X would equal 46 degrees

Answer:

B)2

Step-by-step explanation:

We want to figure out the 415th digit of this repeating decimal.

\( \dfrac{2}{7} = 0. \overline{285714}\)

Obviously it's almost impossible and absurd to find the answer by writing down all the 415 digits. So instead we're going to use some tricks to do so.

Finding the 415th digit:

There're 6 repeating digits. dividing 415 by 6 yields 69.17. Now multiplying 69 by 6 yields 414 which means that the 414th digit of the repeating decimal would be the last digit of the repeating digits, that is,4 and hence The 415th digit of the repeating decimal is gonna be 2. Hence the answer is B

B is the answer

Does 6/10+8/100 = 14/10 or 68/10??

Answers

Answer:

The answer is 68/100 or 17/25

Step-by-step explanation:

To solve this problem, you need to find common denominators. In this equation, the easiest way to do this is to make both fractions have a denominator of 100. 8/100 is already in the proper denominator, and 6/10 can be multiplied by 10 to get 60/100. After adding, you get 68/100 which simplifies to 17/25
