Answer:
Option (4)
Step-by-step explanation:
From the picture attached,
Side lengths of the triangles have been given in the picture attached.
If these triangles are similar, their corresponding sides will be proportional.
By this property of similarity,
[tex]\frac{19.5}{5}= \frac{20}{8}[/tex]
3.9 = 2.5
Which is not true.
Therefore, these triangles are not similar.
Option (4) will be the answer.

Josh hit a baseball straight up into the air. The equation below describes the
height of the ball (h), in meters, as a function of time (t) in seconds.
h(t) = -9.8t2 + 30t + 1.5
What is the height of the ball after 3 seconds?
Answer:
3.3 meters
Step-by-step explanation:
h(3)=-9.8(3)^2+30(3)+1.5
=-88.2+90+1.5
=3.3
Does the point (5, 8) satisfy the inequality 2x + y > 18?
Answer:
The answer is...... NO
Step-by-step explanation:
Step 1: Plug in your values in the x and y cordinates.
2(5) + 8 > 18
Step 2: Solve
Then you multiply 2 and 5 and get 10.
SO then your equation should look like this:
10 + 8 > 18
The answer to the question is no because in order for this to work it would need to be the greater than or equal to sign, which looks like this ≥.
Hope this helps and have a great day! :)

Consider the figure below.
What are the values of x and y?
Answers:
x = 14
y = 14
==========================================
Explanation:
The tickmarks indicate the sides x and y are the same length.
So y = x or x = y
We can use the Pythagorean theorem to say
a^2 + b^2 = c^2
x^2 + y^2 = (14*sqrt(2))^2
x^2 + x^2 = 14^2*(sqrt(2))^2
2x^2 = 196*2
x^2 = 196 ...... divide both sides by 2
x = sqrt(196)
x = 14
This must mean that y = 14 as well.
This triangle is an isosceles right triangle. We also consider it a 45-45-90 triangle because the three angles are 45, 45, and 90 degrees.
For any 45-45-90 triangle, the hypotenuse is always sqrt(2) times the leg length.
hypotenuse = leg*sqrt(2)

A group of students formed a circle during a game.
The circumference of the circle was about 43.96 ft. ,
and the diameter of the circle was 14 ft.
Which expression best represents the value of π?
Answer and Step-by-step explanation:
C = circumference = 43.96
d = diameter = 14
C = [tex]\pi d[/tex]
Divide both sides by d.
[tex]\frac{C}{d} = \pi[/tex]
[tex]\frac{43.96}{14}[/tex] = [tex]\pi[/tex]

the interior angles formed by the sides of a quadrilateral have measures that sum to 360 degrees. what is the value of x? enter your answer in the box
x =_____
Answer:
x = 59
Step-by-step explanation:
since the quadrilateral add up to 360 degrees,
X + X + (2x + 3 ) + (2x + 3) would equal 360 degrees
x + x + (2x + 3) + (2x + 3) = 360
6x + 6 = 360, addtion
6x = 354, subtraction
x = 59, division
5,15,35,65 solve the rule and the next term
Answer:
105
Step-by-step explanation:
Given the sequence of numbers
5,15,35,65
First lets get the common difference
d1 = 15-5 = 10
d2 = 35 - 15 = 20
d3 = 65-35 = 30
We can see that the differences form an arithmetic sequence
10, 20, 30..
Let's get the next term fist
Tn = a + (n-1)d
T4 = 10+(4-1)(10)
T4 = 10 + 3(10)
T4 = 10+30
T4 = 40
This means that the next term of the original sequence will be gotten by adding 40 to the preceding value
Next term = 65 + 40
Next term = 105
Hence the next term is 105

A.) 15.7in
B.) 31.4in
C.) 40in
D.) 62.8in
Answer:
31.4 in
Step-by-step explanation:
This is a tricky question,
if you observe the shape carefully, you will notice that if you mirror (flip outward) each curve surface of each quardrant, what you will end up with is a complete circle with a radius of 5 inches.
Hence the combined length of all the curved surfaces is simply the circumference of the circle, given by:
Circumference = 2πr
= 2 x 3.14 x 5
= 31.4 in
A desk drawer is shaped like a rectangular prism. The height of the drawer is 7 inches. The bottom of the drawer has an area of 210 square inches.
Answer:
We know the volume formula of rectangular prism is:
Volume = Length × Width × Height
We are given:
Volume = 1428 in³
Height = 6 in
Length = 17 in
Width = p
Apply the formula!
1428 = 6 × 17 × p
1428 = 102p
Divide by 102 on either side to isolate p
p = 14
The width is 14 inches

Is the function increasing or decreasing over the interval (-3,-1)? Explain.
Explanation:
The curve is going downhill as you move from left to right, and as you move from x = -3 to x = -1.
The interval notation of (-3,-1) means -3 < x < -1.
Since the curve is going downhill on this region, this means the function is decreasing on this interval.
Yes, the function is decreasing over the interval (-3,-1).
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given interval is (-3, -1).
The curve is going downhill as you move from left to right, and as you move from x = -3 to x = -1.
The interval notation of (-3,-1) means -3 < x < -1.
Since the curve is going downhill on this region, this means the function is decreasing on this interval.
