Answer: 101.03 cm
Step-by-step explanation:
Given
The height of the person is [tex]h=175\ cm[/tex]
Sun is [tex]60^{\circ}[/tex] above the ground
Suppose x is the length of the shadow
From the figure, we can write
[tex]\Rightarrow \tan 60^{\circ}=\dfrac{h}{x}\\\\\Rightarrow x=\dfrac{h}{\tan 60^{\circ}}\\\\\Rightarrow x=101.03\ cm[/tex]
So, the length of the shadow is 101.03 cm

A group of 20 people are going to run a race. The top three runners earn gold, silver, and bronze medals. How many outcomes are possible for these awards?
Answer:
There are 6,840 possible outcomes for these awards.
Step-by-step explanation:
Given that a group of 20 people are going to run a race, and the top three runners earn gold, silver, and bronze medals, to determine how many outcomes are possible for these awards, the following calculation must be performed:
20 x 19 x 18 = X
380 x 18 = X
6.840 = X
Therefore, there are 6,840 possible outcomes for these awards.
Total outcomes that are possible for these awards are 6840 outcomes, calculated using permutation.
Total number of people=20
what is the difference between permutation and combination?permutation means the arrangement of items while the combination is all about the selection of some out of many.
let us say start with the gold medal
no of ways a gold medal can be given = ²⁰C₁ = 20
Now, the number of people left is 19
no of ways a silver medal can be given = ¹⁹C₁ = 19
Now, the number of people left is 18
no of ways a bronze medal can be given = ¹⁸C₁ = 18
possibility of total outcomes=20*19*18 = 6840ways
Therefore, total outcomes that are possible for these awards=6840

Write an equation in slope-intercept form for the line that is parallel to the line 6x + 2y = 2 and passes through the point
(-1, 7).
Answer:
[tex]y=-3x+4[/tex]
Step-by-step explanation:
Hi there!
What we need to know:
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)Parallel lines have the same slope (m) and different y-intercepts (b)1) Determine the slope (m)
[tex]6x+2y=2[/tex]
Rearrange this equation in slope-intercept form (so it's easier for us to identify the slope)
Subtract 6x from both sides to isolate 2y
[tex]6x+2y-6x=-6x+2\\2y=-6x+2[/tex]
Divide both sides by 2 to isolate y
[tex]y=-3x+1[/tex]
Now, we can tell clearly that -3 is in the place of m. Therefore, because parallel lines have the same slope, we know that the line we're solving for will also have a slope of -3. Plug this into [tex]y=mx+b[/tex]:
[tex]y=-3x+b[/tex]
2) Determine the y-intercept
[tex]y=-3x+b[/tex]
Plug in the given point (-1,7)
[tex]7=-3(-1)+b\\7=3+b[/tex]
Subtract 3 from both sides
[tex]7-3=3+b-3\\4=b[/tex]
Therefore, the y-intercept of the line is 4. Plug this back into [tex]y=-3x+b[/tex]:
[tex]y=-3x+4[/tex]

OB. 107%
C. 85%
D. 22%
Answer:
107%
Step-by-step explanation:
because if we look at the x-axis, Discount (%)
and look at 35 which is between 30 and 40
and start going up we get near 100
so
107%
or?
we use the two points and with that we find the slope first
[tex]\frac{y2-y1}{x2-x1}[/tex]
plug in (20,62) and (10,32)
[tex]\frac{32-62}{10-20}[/tex]
equals
[tex]\frac{-30}{-10}[/tex]
simplify to 3
then we use
y - y1 = m (x - x1)
y - 62 = 3 (x - 20)
y - 62 = 3x - 60
add 60 from both sides
y - 2 = 3x
add 2 to both sides
y=3x+2
then plug in 35
y= 3(35) + 2
which is
107

Step-by-step explanation:
First you simplify 2 3/5, which can be 2.6. You will find half of it so 2.6 divided by 2 equals 1.3. She traveled 1.3 miles or 1 3/10 miles before she stopped.
Is 8 a solution to 48 < 4x?

Answer:
No
Step-by-step explanation:
We need to tell that whether 8 satisfies the given inequality. The inequality is ,

now substitute x 12 is equal to 8 and check whether if it satisfies the given inequality.Putting x = 8

Jamal's friends toss 12 balls to him at the same time. Three balls are red, 3 are green, 3 are blue, and 3 are white. Jamal manages to catch 5 of the balls.
What is the probability that he catches 2 red balls and 1 ball of each of the other colors?
Answer:
81/792 or 9/88 or 10.2%
Step-by-step explanation:
Possibility: nCr(12,5) = 792
Red: nCr(3,2) = 3
Blue, Green, White: nCr(3,1) = 3
3 * 3 * 3 * 3 = 81
81/792 simplified is 9/88 percentage is 10.22%
The probability that Jamal will catch 2 red balls and 1 ball of each of the other colors is 0.1025.
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lies in the close interval of 0 and 1 [0,1].
The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.
The total numbers of balls are 12.
Each color has 3 balls.
If total 12 balls are tossed, the number of ways of catching 5 of them is,
¹²C₅ = 792
The number of ways of catching 2 red balls out of 3 is ³C₂ = 3
The number of ways of catching 1 green ball out of 3 is ³C₁ = 3
The number of ways of catching 1 blue ball out of 3 is ³C₁ = 3
The number of ways of catching 1 white ball out of 3 is ³C₁ = 3
Thus, the probability as per the question is given as follows,
(3 × 3 × 3 × 3)/792
= 81/792
= 0.1025
Hence, the probability of catching 2 red balls and 1 ball of each of the other colors is 0.1025.

Find the measure of x and y (3x-3) (4y+4) 60 degrees
Answer:
y=29
X=21
Step-by-step explanation:
180-60=120
4y+4=120 get y by itself and remember that what ever you do to one side you do to the other.
Alternate interior angles are congruent so 3x-3=60
Hence, the values of [tex]y=29,x=21[/tex].
What is a degree?
A degree, usually denoted by °, is a measurement of a plane angle in which one full rotation is [tex]360[/tex] degrees.
Here given that,
The measure of [tex]x[/tex] and [tex]y[/tex] is
[tex](3x-3) (4y+4)[/tex] and the angle is [tex]60[/tex] degrees.
As we know the sum of three angles is [tex]180[/tex] a degree.
[tex]180-60=120[/tex] degree
Since [tex]4y+4=120[/tex] get [tex]y[/tex] we are doing it on the one side so we need to do it on the other side also.
And the alternate angles are congruent [tex]3x-3=60[/tex] degrees.
Hence, the values of [tex]y=29,x=21[/tex].

If AM = 12x + 8 and MB = 10x + 15, then AM = ?
Answer:
AM = 50
Step-by-step explanation:
12x + 8 = 10x + 15
subtract 10x from both sides
2x + 8 = 15
subtract 8 from both sides
2x = 7
divide both sides by 2
x = 3.5
-----------------------------
AM = 12x + 8
AM = 12(3.5) + 8
AM = 42 + 8
AM = 50
