Answer and Step-by-step explanation: With the constant velocity motion formula, we can determine constant velocity of the object in motion whose data we collected:
x = x₀ + vt
Velocity can be calculated as:
[tex]v=\frac{x-x_{0}}{t}[/tex]
[tex]v=\frac{70-40}{10}[/tex]
v = 3 m/s
The beginning of the data collect, object is 40m away, then x₀ = 40.
So, equation modeling the object's path is x = 40 + 3t.

The required similarity ratio for the given triangle is given as 1/3, and option B is correct.
What are Similar triangles?Similar triangles are those triangles that have similar properties,i.e. angles and proportionality of sides.
Here,
Consider the triangles ABC to PQR,
Taking the ratio of the corresponding sides,
AB/PQ = BC /QR = AC/PR
2 / 6 = 2/6 = 1/3
1/3 = 1/3 = 1/3
Thus, the required similarity ratio for the given triangle is given as 1/3, and option B is correct.

QUESTION 7
Solve for x.
(3x + 32)
(5x-8)
O a. 3
b. 12
O c. 20
O d. 19.5
Answer:
The answer is x = 20
Step-by-step explanation:
If you set both equations equal to each other and solve for x, you will get 20.
3x+32 = 5x-8 add 8 to both sides
3x+40 = 5x subtract 3x from both sides
40 = 2x divide by 2 on both sides
20 = x

Adele is building a snowman. There are 3 hats and 8 scarves to choose from. For the nose, Adele has 3 options. If Adele uses one of each item, how many different snowmen can she make?
Answer: 72
Step-by-step explanation:
Given: Choices for hats = 3
Choices for scarves = 8
Choices for nose = 3
Using the Fundamental principle of counting, the number of different snowmen she can make = (Choices for hats) x (Choices for scarves) x (Choices for nose)
= 3 x 8 x 3
= 72
Hence, the number of different snowmen she can make = 72
2. Each letter from the word "MASSACHUSSETT " is written on a separate 20 points
piece of paper and put in a bag. What is the probability of selecting the
letter S, as a fraction in lowest terms ? *
1 out of 2
4 out of 11
0 4 out of 13
1 out of 3
Answer: 4 out of 13
Step-by-step explanation:
Total letters in "MASSACHUSSETT " = 13
Number of S = 4
Probability of an event = [tex]\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
The probability of selecting the letter S = [tex]\dfrac4{13}[/tex] [already in lowest term as gcd(4,13)=1]
Hence, the probability of selecting the letter S = 4 out of 13.

what is 13.045 rounded to the nearest tenth
Answer:
13.0
Step-by-step explanation:
Place value can be defined as the numerical value representing a digit owing to its position in a number. Some examples of the various place values used in representing each digit are tenths, hundredths, thousandths, unit, tens, hundreds, thousands etc.
For the number 13.045;
The place value of 1 is tens.The place value of 3 is units.The place value of 0 is tenths.The place value of 4 is hundredths.The place value of 5 is thousandths.Therefore, 13.045 to the nearest tenth is equal to 13.0.
NB: This is because the value of the hundredth term (4) is less than 5 and as such cannot be rounded up.
Consider the following rational numbers
-11, 12, 13
Order the numbers from teast to greatest Type your answer in the box below.
Order the numbers'absolute values from least to greatest Type your answer in
the box below
Is the order of the rational numbers in part (a) different from the order of the
numbers absolute values in part (b)?
Explain why or why not
Answer:
The numbers are already in order, least to greatest. –11 is much less than 12 and 13 IF the signs on these numbers are correct.
The absolute values will be in the same order 11,12,13 as the signs on the numbers make no difference when considering absolute values..
Step-by-step explanation:
If we had negative signs on –12 and –13, the order for part a would be reversed. –13 is less than –12 and –11
Use the quadratic formula to solve the equation.

Find the sum of measures of the interior angles of the given figure
The sum of interior angles of the given 6 sided polygon is 720°. Therefore, option A is the correct answer.
What is the formula for sum of interior angle of a polygon?(n-2)180° is the formula for computing the total internal angles, where is the total number of sides. In a regular polygon, all internal angles are equal. Interior angle of a polygon = sum of interior angles number of sides is the formula for determining the amount of an interior angle.
In the given figure, there are 6 sides.
The sum of interior angles = (n-2)×180°
= (6-2)×180°
= 4×180°
= 720°
Therefore, option A is the correct answer.

A tree is broken at a height of 5 m from the ground and its top touches the ground at a distance of 12 m from the base of the tree find the original height of the tree
Answer:
The original height of the tree is 18 m.
Step-by-step explanation:
Please see attached photo for explanation.
From the diagram, we shall determine the value of 'x'. This can be obtained by using the pythagoras theory as follow:
x² = 5² + 12²
x² = 25 + 144
x² = 169
Take the square root of both side
x = √169
x = 13 m
Finally, we shall determine the original height of the tree. This can be obtained as follow.
From the question given above, the tree was broken from a height of 5 m from the ground which form a right angle triangle with x being the Hypothenus as illustrated in the diagram.
Thus, the original height of the will be the sum of 5 and x i.e
Height = 5 + x
x = 13 m
Height = 5 + 13
Height = 18 m
Therefore, the original height of the tree is 18 m.

[tex]\tt Step-by-step~explanation:[/tex]
You cannot simplify this expression, but instead, you can factor it like this:
Find the Greatest Common Factor (GCF) of the three numbers.
[tex]\tt 10 \div 5=2\\6 \div 3 = 2\\6 \div 3 = 2\\GCF=2[/tex]
Since the GCF is 2, we can factor 10, 6, and 6 by dividing them by two and placing them inside parenthesis.

When you multiply 2 to each of the terms, you would end up with 10a + 6b + 6c.

many guests can Jaden invite?
Answer:8
Step-by-step explanation:
6 is 120

Answer:
3 more guests

You just to have to add 120 plus 30 until you reach 200.
120+30=150
150+30=180
180+NO it is going to be too much.30=210
Then if you see I did 180+30 it gave me more than 200 but they only have the budget of 200. So you will have $10 extra. ANd then you can only invite 3 more guest.
