Answers
Answer:
0.12 Miles
Step-by-step explanation:
Given:
Joakin = 0.3 Miles from Keith
Layla lives 0.4 times as far as Joakim
Solution:
If Joakin lives 0.3 miles from keith and Layla lives 0.4 times as far from keith as Joakim that mean to multiply 0.3 by 0.4.
0.3 x 0.4 = 0.12
Hence, Layla live 0.12 Miles from Keith.

An investigator at a crime scene found a triangular piece of torn fabric. The investigator remembered that one of the suspects had a triangular hole in their coat. Perhaps it was a match. Unfortunately, to avoid tampering with evidence, the investigator did not want to touch the fabric and could not fit it to the coat directly.
a) If the investigator measures all three side lengths of the fabric and the hole, can the investigator make a conclusion about whether or not the hole could have been filled by the fabric?
b) If the investigator measures two sides of the fabric and the included angle and then measures two sides of the hole and the included angle can he determine if it is a match? Explain.
Answers
9514 1404 393
Answer:
a) yes
b) yes
Step-by-step explanation:
a) Triangles can be proven congruent by the SSS postulate, so knowing the three side lengths is sufficient to demonstrate the piece will fit in the hole.
__
b) A triangle can be solved (completely specified) if two sides and the included angle are known. Those measurements on the fabric and the hole allow all side lengths and angles of the triangles to be determined completely. Hence the triangles can be shown congruent as a result.
_____
Additional comment
Showing SSS congruence generally means demonstrating corresponding sides are the same length. However, the three side lengths completely specify the triangle. The side lengths can always be made corresponding if they are listed in some order, for example, shortest to longest.
Showing SAS congruence requires that corresponding sides and angles be shown congruent. However, an SAS specification of a triangle is sufficient to permit determination of all sides and angles. Specifically, the third side length can be found using the Law of Cosines, and the remaining angles can be found from either the Law of Sines or the Law of Cosines.

can someone write this equation is slope intercept form?
Answers
Answer:
To find the slope use the distance formula. The distance formula is Y2-Y1/X2-X1.
300-100/10-2
200/8
25
So, the equation so far is y=25x+b. To find the y-intercept, substitute one of the points into the equation.
100=25(2)+b
100=50+b
b=50
The equation of the line is y=25x+50.
:)
Answer:
y = 25x + 50
Step-by-step explanation:
The graph shows this line passing through (2, 100) and (10, 300). Here x changes from 2 to 10, a 'run' of 8, and y changes from 100 to 300, a 'rise" of 200. Hence the slope of this line is m = rise / run = 200/8 = 100/4 = 25.
The basic slope-intercept form is y = mx + b. We know that m = 25. Taking coordinate values from (2, 100), we let x = 2 and y = 100:
100 = 25(2) + b, or 100 = 50 + b.
Therefore, the y-intercept is 50, and the desired equation in slope-intercept form is
y = 25x + 50

A surveyor is standing 75 feet from the base of a building. The angle of elevation to the top of the building is 60°. Approximately how tall is the building? Round the answer tot he nearest tenth.
Answers
Using the principle of Pythagoras, the height of the building is approximately 129.9 feets.
Using SOHCAHTOA :
Tanθ = opposite / AdjacentTan(60) = height / 75
1.7320508 = height / 75
Height = 1.7320508 × 75
Height = 129.90 feets.
Hence, the height of the building is 129.9 feets.

Eduardo is in 8th grade and gets an allowance of $10 every week from his parents. He has saved up $110 so far in a savings account. He wants to buy some new clothes since his current wardrobe is getting worn out. He sets a budget of $250 for himself.
a: How much more money does Eduardo need before he can go shopping?
b: How many months will it take Eduardo to save this much money?
Answers
Answer:
eduardo needs 140 more dollars before he can go shopping
3 months
Step-by-step explanation:
a: Eduardo needs $140 more money before he can go shopping.
b: 3.5 months will it take Eduardo to save this much money.
a: To find out how much more money Eduardo needs before he can go shopping, you subtract his current savings from his budget:
Amount needed=Budget−Current savings
=$250−$110
=$140
Hence, Eduardo needs $140 more money before he can go shopping.
b: To calculate how many months it will take Eduardo to save this much money, we need to divide the remaining amount he needs by his weekly allowance:
Number of weeks needed=Amount needed/weekly allowance
=140/10
=14
Since there are roughly 4 weeks in a month, you can estimate that it will take Eduardo approximately 14 weeks ÷ 4 weeks/month
= 3.5 months.
Hence, it will take Eduardo about 3.5 months to save up the remaining $140 he needs.

A box has colored balls (12 red, 10 green, 6 light blue and 8 yellow). What is the probability of drawing 2 red balls?
Answers
9514 1404 393
Answer:
1/14
Step-by-step explanation:
The probability of drawing the first red ball is 10/36, the number of reds divided by the number of balls.
The probability of drawing the second red ball is 9/35, the remaining number of reds divided by the remaining number of balls.
P(2 red) = (10/36)(9/35) = 1/14
When a ball is dropped onto a flat floor, it bounces to 65% of the height from which it was dropped. If the ball is dropped from 80 cm, construct a sequence consists of the first, second and third term which represents the height of each bounce from the first drop.
13n
Show that the height of nth bounce, Tn is = 80 .
20
Hence, find the height of the fifth bounce
Answers
Using a geometric sequence, it is found that:
The rule for the height of the nth bounce is:[tex]a_n = 52(0.65)^{n-1}[/tex]
The height of the fifth bounce is of 9.28 cm.In a geometric sequence, the quotient between consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given by:
[tex]a_n = a_1q^{n-1}[/tex]
In which [tex]a_1[/tex] is the first term.
In this problem:
Bounces to 65% of the height from which it was dropped, thus the common ratio is of [tex]q = 0.65[/tex].Dropped from 80 cm, thus, the height of the first bounce is [tex]a_1 = 80(0.65) = 52[/tex].Thus, the rule for the height of the nth bounce is:
[tex]a_n = 52(0.65)^{n-1}[/tex]
The height of the fifth bounce is [tex]a_5[/tex], thus:
[tex]a_5 = 52(0.65)^{5-1} = 9.28[/tex]
The height of the fifth bounce is of 9.28 cm.

Answer: 0.875
Step-by-step explanation:
The answer that has already been given is perfect in and by itself. I just want to give you some methods for doing these type of questions so that you won’t stagger when you see these type of questions in exams (like the SAT).
Whenever you see such questions, remember the following things. These are conversions of English words to Mathematical tools.

I’ll give you an example through a question.
What percent of 200 is 5?
Ans: Replace English words by mathematical tools according to the rules I told you.

Calculate x. On calculating, x comes out to be

So, 2.5 percent of 200 is 5.

You want 87.5%. By the rules, % means divided by 100. So

Disregard the next section if you know how to convert a decimal to a fraction
Section Starts
First, I’ll write the decimal form. Whenever you divide by a number that is in form of 1 followed by
n
number of zeroes. (here 1 is followed by 2 zeroes), you should shift the decimal point to the left side by n places.
In this case, shift decimal point in 87.5 to the left by 2 places. So this becomes 0.875.
This is the answer in decimal point.
Now simultaneously, I’ll teach you how to convert a decimal into a fraction.
Here, you see 2 types of “numbers”. One to the left side of the decimal point and one to the right side of the decimal point.
Here, left side of decimal point is 0 and right side of decimal point is 875.
Count the number of digits in the number to the right side of the decimal point (Here, the number of digits is 3)
Remove the decimal point and divide the number by a number formed by 1 followed by the “digits” we obtained (i.e. 3).
So, 875/1000. Simplify this, and you get your answer.
