Answers

Answer 1

Answer:

Triangle E or D

Step-by-step explanation:

Is not the right one

Answer 2

Triangle C and Triangle D are not right angle triangles.

What is right angle triangles?

Right Angle Triangle is a triangle in which one angle is right angle or 90 angle , means in which two sides are perpendicular.

Following length of the sides of triangles are given

Triangle A=3,4,5  , Triangle B=5,12,13  Triangle C= 10,12,15

Triangle D= 3,6,145  and Triangle E=8,15,17

According to Pythagoras theorem ,  in right angle triangle the square of biggest side is equal to the sum of square of remaining two sides.

So,

The solution for triangle A,

5²=4²+3²

25 = 16 + 9= 25  

Triangle A is right angle triangle.

The solution for triangle B,

13²= 5² + 12²

169= 25+144=169

Triangle B is a right angle triangle.

The solution for triangle C,

15²=12²+10²

225= 144+100

225=244

Triangle C is not right angle triangle.

The solution for triangle D,

145²=6²+3²

21025=36+9=45

Triangle D is not a right angle triangle.

The solution for triangle E,

17²=15²+8²

289=225+64=289

Triangle  E is right angle triangle.

Therefore, Triangle C and Triangle D are not right angle triangle.

A pyramid has a square base with sides that measure 10cm and a height of 14cm. What is the slant height of the pyramid?
A)17.2 cm
B)14.9 cm
C)13.2 cm
D)12.1 cm

Answers

the answer is A im pretty sure

The solution is,  the slant height of the pyramid is 14.9 meters.

What is Pythagorean theorem?

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

here, we have,

we know that,

The slant height is the height of a triangle making up the base of the pyramid.

We can imagine a right triangle with one leg being a vertical line from the peak of the pyramid going down to the center of the base, and the other leg going from the center of the base to the center of one edge of the base.

And finally, the hypotenuse will join the ends of those 2 lines together and will also be the slant height of the pyramid.

Then we can easily use the Pythagorean theorem to determine the slant height.

So, S = sqrt((10/2)^2 + 14^2)

S = sqrt(5^2 + 14^2)

S = sqrt(25 + 196)

S = sqrt(221)

S = 14.9

So the slant height of the specified pyramid is 14.9 meters.

Mrs. Jones was very proud of her apple tree. One autumn, after harvesting her apples, she called her three sons together. “Here are 150 apples,” she said. “I want you to take them to the market tomorrow and sell them for me.” She gave Paul 15 apples, Nick 50, and Ben 85. “Your job,” added Mrs. Jones, “is to sell the apples in such a way that each of you brings home the same amount of money.” How do they do it?

Good Luck!! First Right Answer May Get Brianliest!!! : )

Answers

I think that the first person who came along to buy apples would have to buy 12 dozen apples at $1 per dozen. Paul’s sells one dozen, Nick sells 4 dozen, and Ben sells seven dozen. After that, Paul has 3 apples, Nick has 2, and Ben has 1. If they all sent their remaining apples at a price of $3, Paul would earn 9 more dollars, Nick would earn 6, and Ben would earn three. That puts them each with a profit of $10.

27x + 15y = ? (9x + ? y)
Please help! I don't understand!

Answers

Answer:

3;5

Step-by-step explanation:

One side of the equation is 27x + 15y, the number of the first blank times 9x needs to be 27x, so it has to be 3. And 3 times {blank} y needs to be 15y, so the second blank has to be 5.

Hope this helps! :)

Answer:

27x + 15y = 3(9x + 5y)

Step-by-step explanation:

27x + 15y = ?(9x + ?y)

3 times 9 = 27

so the first ? would be 3

27x + 15y = 3(9x + ?y)

15/3 = 5

so the 2nd ? would be 5

27x + 15y = 3(9x + 5y)

Simplify to check your work.

27x + 15y = 3(9x + 5y)

27x + 15y = 3(9x) + 3(5y)

27x + 15y = 27x + 15y
