whats the formula for the surface area of a triangle?

Answers

Answer 1

Answer:

use the formula A = 1/2bh, where A = area, b = base, and h = height. Once you have the areas of all sides and faces, you simply add them together to get the surface area.

Hope this helps!

Answer 2
The formula would be depending on the triangular shape. Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. Which creates the formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.

Chucky spent $23.24 on supplies to make cookies for his booth at the show. He made a profit of $24.76. Each cookie was $1, how many cookies did he sell?
c - 23.24 = 24.76
c + 23.24 = 24.76
c - 24.76 = 23.24
c + 24.76 = 23.24

Solve it.
Chucky spent $23.24 on supplies to make cookies for his booth at the show. He made a profit of $24.76. Each cookie was $1, how many cookies did he sell?
5 cookies
1.5 cookies
50 cookies
48 cookies

Answers

Answer:

just do this 24.76min. 23.24 then see what u have got for

Answer:

c - 23.24 = 24.76 (the first option)

48 cookies

Explanation:

Profit is equal to revenue(amount made) minus costs, or r - cost = p. The revenue is 1*cookies sold, or c. So, c - 23.24 = 24.76.

Solving is relatively simple,

c - 23.24 = 24.76

c = 48 (add 23.34 to both sides)

(b) Suppose a car is traveling southwest on King Avenue and turns left onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.

(c) Suppose a car is traveling northeast on King Avenue and turns left onto 4th Street. What is the measure of the angle created by the car's turning? Explain your answer.

Pls work it out for me I'm VERY confused.

Answers

Answer:

c.The measure of the angle created by the car's turning is 105°

Step-by-step explanation:

Suppose a car is traveling east on 4th Street and turns onto King Avenue heading northeast. What is the measure of the angle created by the car's turning? Explain your answer.

180°-70°= 110° ✓

This person  would be driving 110° degrees. ✓

So, what we would do it do 180° subtracted by 70. We need to find how much he turns onto King Avenue heading northeast. So we do 180° because that would be considered a full half turn, so 180° subtracted by 70 and that would give you . . .

180° - 70° =

(Part 2)

Your question states:

Suppose a car is traveling southwest on King Avenue and turns left onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.

This may be a little tricky on this side. These side's are coherent. As we know now that the angel on (King Ave.)  was 110°, we would say the on the (3rd angel through King Ave.) that angel as well would be 110° because that is the angel on top. This would mean that they would be the same. But the thing is, we are finding what is the angel when the car is traveling southwest on King Avenue and turns left onto 3rd Street. This angel would be 70° degrees because as we do 70° + 70° + 110° + 110° = 360°.

This is how we would know that this would be that angel going into (3rd Ave).

My steps: 360° - 110° - 110° = 140°.

140° ÷ 2 = ∡70° ✓

Your correct answer would be

Step #3

Your question states:

Suppose a car is traveling northeast on King Avenue and turns right onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.

Your correct answer would equal 110°. ✓

My steps:

360° - 75° - 75° = 210°

210° ÷ 2 = 105° ✓

Your correct answer would be

A 12ft. tall ladder is leaning against a building. If the bottom of the ladder is 3ft. from the base of the building how high up the side of the building does the ladder reach? Put your answer in the box. Round your answer to the nearest whole number.

Answers

Step-by-step explanation: The Pythagorean theorem states that, in a right triangle, the length of the hypotenuse squared equals the sum of the squares of the other two sides or legs of the triangle.  Algebraically, a2+b2=c2.  In your example, the length of the ladder would be the hypotenuse and the distance from the wall would be one of the legs.  So substitute these values into the equation to get: 32+b2=122 or 9+b2=144 and then subtract 9 from both sides to get b2=135.  Therefore b=√135≈11.62.  If your problem requires an exact answer in its most simplified form, please note that √135=3√15.  Hope this helps you

Answer:

1) c and d

2) 44

3) a and c

1: if 96 is the 100% price and 32% is what you need to find, it is 32 out of 100. 0.32 is the same, as well as 32/100.

2: if you divide the shape into different pieces, i find it easier to find the area. 9 x 3 = 27. 4 x 2= 8. 3 x 3 = 9. 27+8+9=44.

3:  the ratio 8:20 can be simplified down to 2:5 which makes A true. if the ratio is originally blue:red, then for c, 10:4 is the same as 4:10 since it states red to blue instead of blue to red, meaning c is also true.

Answer:

1. C and D.

2. 34

3. A and C

Step-by-step explanation:

1. All you have to do is solve each equation in order to see which ones are equal to the same answer

A. 32 * 96 = 3072

B. 3.2 * 96 = 307.2

C. 0.32 * 96 = 30.72

D. 32/100 * 96 = 30.72

Both C and D have the same answer.

2. Add up all the sides

9+6+5+4+3+3+2+2= 34

3. Look at each answer carefully.

A. There are 2 blue cubes for every 5 red cubes. True

B. When the game has 56 cubes in all, there are 40 red cubes. False

C. The ratio of red to blue cubes is 10:4. True
