Answers
9514 1404 393
Answer:
4.512.5Step-by-step explanation:
Let s represent the smaller number. Then s+8 is the larger number, and their sum is ...
s + (s+8) = 17
2s = 17 -8 = 9
s = 9/2 = 4.5
s+8 = 4.5 +8 = 12.5
The two numbers are 4.5 and 12.5.

Comment on problems of this type
A method is shown here for solving the problem using one equation in one variable. The general solution can be seen to be ...
two numbers = (sum ± difference)/2
Here, that is ...
two numbers = (17±8)/2 = (25, 9)/2 = (12.5, 4.5)

Lucy wasn't allowed to have any pets so she collected stuffed animals instead. She had 36 animals total. 3/12 of them were bears and 4/6 of them were dogs. What fraction of the animals were either dogs or bears?
Answers
3/12 times 3=9/36 bears
4/6 times 6= 24/36dogs
So 33 of the animals were dogs or bears
But to simply add the fractions make the denominator the same by timesing the 4/6 by 2
So 3/12 plus 8/12 is
11/12
So 11/12 is your answer.

identify the similar triangles in the diagram, then sketch them so the corresponding sides and angles have the same orientation.
Answers
The triangle KLM and triangle JKM are congruent triangle
In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.
Triangles that are identical in size and shape are said to be congruent triangles. Inferred from this is that the matching sides and angles are equal. Without checking each of the triangles' sides and angles, we may determine whether two triangles are congruent.
Given a triangle LKJ
We have to find similar triangles in the diagram so the corresponding sides and angles have the same orientation.
By the figure given we can write following things:
LK/LJ = MK/JK
LK/JK = MK/MJ
So the triangle KLM ≅ triangle JKM ≅ triangle JLK
Hence the triangle KLM and triangle JKM are congruent triangle

Answer:
152 yards
Step-by-step explanation:
If you look at the rectangular side, the length is 8, and the width is 5.
The area of this side is 40 yd!
Since this is a 3D shape, there are two of that side.
40 times 2 = 80
Next, the triangle side!
The area of a triangle is base times height divided by 2.
So, this triangle is:
6 times 4 divided by 2 = 12
The area of one triangle side is 12, but there's two!
12 times 2 = 24
Lastly, there's a bottom. 6 times 8 = 48.
Now add them up!
152 yards

The base and corresponding height of a parallelogram are 75 cm and 25 cm. If the other base is 50 cm, find out its corresponding height.
Answers
Answer:
Height of the parallelogram = 37.5 cm
Step-by-step explanation:
As given,
Base of a parallelogram = 75 cm
Height of a parallelogram = 25 cm
As,
we know that
Area = Base × Height
= 75 × 25
= 1875 cm²
As the parallelogram is same
So, Area = Base × Height
⇒1875 = 50 × Height
⇒ Height = [tex]\frac{1875}{50}[/tex] = 37.5 cm
So, we get
Height of the parallelogram = 37.5 cm

Explain how you can use ratios of the side lengths to find the angle measures of the acute angles in a right triangle.
Answers
Answer:
The answer is below
Step-by-step explanation:
Triangles are polygons with three sides and three angles. Types of triangles are isosceles, equilateral, scalene and right angled triangles.
Trigonometric identities are equations that uses trigonometric functions to show the relationship between the angles in a right angle triangle and the sides of the right angled triangle.
If θ be an acute angle in a right angled triangle, hyp. is the hypotenuse side of the angle, opp. is the opposite side to the angle and adj. is the adjacent side to the angle, then:
sinθ = opp. / hyp.v; cosθ = adj. / hyp. ; tanθ = opp. / adj.
