Answer 1

Answer:

78.5 cm^2

Step-by-step explanation:

The formula for the area of a circle is A=pi*r^2. In this case, the radius is 5 and pi is 3.14 so, A=(3.14)(5)^2. When we plug this into a calculator, we get 78.5 which will be the area for the circle. :)

Step-by-step explanation:

Formula for a cone:

V = 1/3 \(\pi\) r² h

Given:

\(\pi\) = 3.14

h=  12

Solution:

We need to find r to plug into formula

We can find r using pythagorean theorem on the triangle

c²=a²+b²               c is always the hypotenuse, longest side

15² = 12² + r²

225 = 144 + r²

r² = 81

r=9

V = 1/3 \(\pi\) r² h

V = 1/3 (3.14)(9²)(12)

V= 1017.36

First Person who gets it right and EXPLAINS will get branliest! :-)

Answers

If I’m correct, it’s 5 since x•x•5=24 isn’t doable
Answer:

5 is the answer.

Review:

What is a cuboid?

A cuboid is a rectangle, but in 3D form.

Do we calculate area or volume in a cuboid?

We calculate the volume for 3D shapes. For 2D shapes, area is used.

If/Then:

Now, if the volume of the cuboid is 24 units³ then:

x × x × y

Now, lets fit all our options to see which one is NOT the dimensions.

Option A:

x × x × 3 = 24 units³

x × x = 12 units³ ✔

This is possible.

Option B:

x × x × 4 = 24 units³

=> x × x = 6 units³ ✔

This is possible.

Option C:

x × x × 5 = 24 units³

=> x × x = 24/5 units³ ❌

This is not possible. This will be our answer.

Option D:

x × x × 6 = 24 units³

=> x × x = 4 units³✔

This is possible.

Conclusion:

So after working on our problem, we can conclude that C is our answer. Hoped this helped.

Answers

step 1: make the fractions improper fractions (36/5) - (21/4)

step 2: find the common denominator between 5 and 4 (20)

step 3: cross multiply them 36/5 x 4 which is going to make the fraction 144/20

step 4: do the same for the other side 21/4 x 5 105/5

step 5: now replace the old fractions with the new ones, 144/20 - 105/20

the answer should be 39/20

simplify to 1 19/20

The solution of the given expression is-

\(7\frac{1}{5} -5\frac{1}{4} = 1\frac{19}{20}\)

We must first transform mixed fractions into improper fractions before we can subtract them.

Let's transform  \(7\frac{1}{5}\)  it into an improper fraction :

\(7 \frac{1}{5} = \frac{(7 * 5 + 1)}{5} = \frac{36}{5}\)

Let's change \(5\frac{1}{4}\)  into an improper fraction now:

\(5\frac{1}{4} = \frac{(5 * 4 + 1)}{4} = \frac{21}{4}\)

We can now subtract the fractions:

To subtract fractions, we need to find a common denominator. The least common multiple or the LCM of 5 and 4 is 20.

Converting the fractions to have a common denominator of 20:

(36/5) * (4/4) = 144/20

(21/4) * (5/5) = 105/20

So the subtraction will be as follows:

\(\frac{36}{5} -\frac{21}{4} =\frac{(36*4)+(21*5)}{4*5} =\frac{144-105}{20}=\frac{39}{20}\)

Therefore, \(7\frac{1}{5} -5\frac{1}{4}\) is equal to  \(\frac{39}{20}\) or,  \(1\frac{19}{20}\) .

The solution of the given expression is-

\(7\frac{1}{5} -5\frac{1}{4} = 1\frac{19}{20}\)

I’m learning this too. Slopes confuse me

Answer:

\(slope=-2\)

Step-by-step explanation:

Alrighty, I would love to help. So with slopes, we usually are given t-tables as such to determine how a line will look on a coordinate plane. When given the lines, we use the formula:

\(\frac{rise}{run}\)

Although, we are given the coordinates instead which our formula then is:

\(\frac{y_{2-y_{1} } }{x_{2}-x_{1} }\)

Although this may look confusing all it is saying is that we are going to do the following:

We have coordinates (-1,1) and (0,-1)

By applying the formula given earlier, all it is saying is that we are going to take -1-1 and 0-1 like such:

\(\frac{y_{2-y_{1} } }{x_{2}-x_{1} } \\\\\frac{-1-1}{0-1} \\-1-1=-2\\0-(-1)=1\\slope=\frac{-2}{1} \\slope=-2\)

When working with fractions, any number over 1 is just the numerator(top number) say if we had 10/1, then our answer is 10 since we are dividing 10 by 1.

whats the surface area?

Answers

Answer:

  1108 in²

Step-by-step explanation:

You want the total surface area of the pentagonal prism shown.

Base area

The area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...

  A = LW +1/2bh

  A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches

Lateral area

The lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.

  LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches

Total area

The total surface area of the figure is the sum of the two base areas and the lateral area:

  SA = 2(114 in²) +880 in² = 1108 in²

The surface area of the composite figure is 1108 in².
