Answer:
8 meters
Step-by-step explanation:
This is a question that deals with Proportion
Height of flagpole/Shadow of flagpole = Height of Luke/Shadow of Luke
Length of the shadow of Luke = x
= 12/24 = 4/x
We cross Multiply
12 × x = 24 × 4
x = 24 × 4/12
x = 8 meters
Hence, the length of the shadow of Luke = 8 meters

Thomas is going to flip an unfair coin 2 times. Each coin flip is independent, and the probability that the coin flips
heads is 20% each time.
Please tell me the possible outcomes, thank you.
Answer:
Step-by-step explanation:
The probability of flipping heads is 20% (or 0.2), the probability of flipping tails is 80% (or 0.8).
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
There are four possible outcomes when flipping an unfair coin twice, since each coin flip has two possible outcomes (heads or tails).
We can use H to represent heads and T to represent tails.
The possible outcomes are:
HH (both flips are heads)
HT (first flip is heads, second flip is tails)
TH (first flip is tails, second flip is heads)
TT (both flips are tails)
Each of these outcomes has a certain probability associated with it.
Since the probability of flipping heads is 20% (or 0.2), the probability of flipping tails is 80% (or 0.8).
Hence, the probability of flipping heads is 20% (or 0.2), the probability of flipping tails is 80% (or 0.8).

How would i do this??:: Some kinds of fruit juice are only 10% juice. Other brands are 40% juice how much of each kind of juice should be mixed together to form 5 gallons of punch which is 25% juice?
Answer:
You should mix
2.5 gallons of the first juice with
2.5 gallons of the second juice
Step-by-step explanation:
Step one
Let the first kind of juice be x
Let the second be y
Given x contain 10% juice
and y contains 40% juice
So for the percentage constituent concentration of each the expression is
0.1x+ 0.4y=0.25(5)
0.1x+0.4y=1.25—----------------1
Step two
Also for the volume of the mixture, we are working with 5 gallons hence the expression
x+y=5-------------------------------2
The system of equation for the situation is
0.1x+0.4y=1.25------1
x+y=5-------------------2
From equation 2
x=5-y
Put x=5-y in the equation
0.1(5-y) +0.4y=1.25------1
0.5-0.1y+0.4y=1.25
0.3y=1.25-0.5
0.3y=0.75
Dividing both sides by 0. 3
y=0.75/0.3
y=2.5
x=5-y
x=5-2.5
x=2.5
The mixture should consist of
2.5 gallons of the first juice with
2.5 gallons of the second juice
Marshall is writing an equivalent equation to solve for x. What should be his next step? 5 x + 4 y = 8. 5 x + 4 y minus 4 y = 8 minus 4 y. 5 x = 8 minus 4 y.
Answer:
d)Divide both sides of the equation by 5.
Step-by-step explanation:
Marshall is writing an equivalent equation to solve for x. What should be his next step?
5x+4y=8
5x+4y-4y=8-4y
5x=8-4y
a)Add 5x to both sides of the equation.
b)Subtract 5x from both sides of the equation.
c)Multiply both sides of the equation by 5.
d)Divide both sides of the equation by 5.
5x + 4y = 8
Subtract 4y from both sides
5x + 4y - 4y = 8 - 4y
5x = 8- 4y
Divide both sides by 5
5x / 5 = (8 - 4y) / 5
x = (8 - 4y) / 5
Marshall's next step should be to divide both sides of the equation by 5
Answer: D)Divide both sides of the equation by 5.

if BD and EG are parallel lines and m∠DCF = 125°, what is m∠DCA
Answer:
55
Step-by-step explanation:
FCA equals 180 degrees so you subtract 180 from 125 and get 55 degrees.
Answer:
55
Step-by-step explanation:
Just subtract 180 and 125
You said that m∠DCF = 125° right?
And the m∠DCF and m∠DCA are linear pair because they have angles that share a side, so supplementary angles = 180
m∠DCF + m∠DCA = 180
replace (since m∠DCF = 125):
125 + m∠DCA = 180
-125 -125
m∠DCA = 180 - 125
m∠DCA = 55
just need 5 and 6 done due in 20 minutes plz help
Step-by-step explanation:
5. Let the equation of the line be y = mx + c
m = (6-15)/(2-(-1)) = -3
sub (2, 6) and m = -3:
6 = -3(2) + c
c = 12
Equation of the line: y = -3x + 12
6. Let the equation of the line be y = mx + c
y-intercept of 7 means c = 7
y = mx + 7
x-intercept: value of x when y = 0
therefore, sub (4, 0):
0 = m(4) + 7
m = -7/4
Equation of the line: y = -7/4x + 7

when simplify 4^7, using a calculator, you get 16384. When you simplify 4^-2 , you get 0.0625. When multiplied together, the total is 1024, which is an integer. Answer a, b, and c were not integers, because when multiplied or divided, the answer was less than zero and showed up as a decimal starting with 0.*** . An integer is defined as any whole number, and not a fraction, therefor D is the only correct answer.

A pitcher can hold 5.2 liters of water. How many 0.4 liter glasses of water can be poured from the pitcher? *
13 glasses can be poured
Hope I helped
Answer:
13
Step-by-step explanation:
number of glasses = total quantity of water / quantity of one cup
n = 5.2/0.4
n = 52/4 (multiply numerator and denominator with 10)
n = 13
therefore it can be poured into 13 cups
Write an equation that could be used to find three consecutive odd integers whose sum is -3
Answer:
2x+1 + 2x+3 + 2x+5 = -3Step-by-step explanation:
2x+1 - the first odd integer
2 x+1 + 2 = 2x+3 - the next odd integer consecutive to 2x+1
2x+3+2 = 2x+5 - the odd integer consecutive to 2x+3 (the third consecutive odd integer)
2x+1 + 2x+3 + 2x+5 - the sum of three consecutive odd integers
therefore the equation:
2x+1 + 2x+3 + 2x+5 = -3
6x + 9 = -3
6x = -12
x = -2
2x+1=2(-2)+1=-3
2x+3=2(-2)+3=-1
2x+5=2(-2)+5=1
the three consecutive odd integers whose sum is -3 are: -3,-1,1

(3,-1). What is the image of point (4,2) under the
same translation?
Answer:
Step-by-step explanation:
REF: 060309a
ANS:
(9,−2)
(x,y)-->(x+5,y-4)
Transformation involves changing the position of a point.
The image of the translation is (9,-2).
The point is given as:
[tex]\mathbf{A= (-2,3)}[/tex]
The image of the point is:
[tex]\mathbf{A'= (3,-1)}[/tex]
The translation rule is calculated as:
[tex]\mathbf{T = <x + 3--2,y-1-3>}[/tex]
[tex]\mathbf{T = <x + 5,y-4>}[/tex]
So, the image of (4,2) is:
[tex]\mathbf{Image = (4 + 5, 2 -4)}[/tex]
[tex]\mathbf{Image = (9, -2)}[/tex]
Hence, the image of the translation is (9,-2).

David pays $335 in advance on his account at the gym. Each time he visits the gym , $6 is deducted from the account. Write an equation in y = max + form that represents the value remaining in his account after x visits
Answer:
x = 335 - (6 * v)
Step-by-step explanation:
In order to calculate the value remaining, we need to first multiply the daily cost of each visit by the number of visits made to the gym which is represented by the variable (v). Once we have this cost of all the days then we subtract this amount from the current account balance in order to get the new remaining balance which is represented by x.
x = 335 - (6 * v)

Zeke kicked a football 92 yards. Zane estimated it at 90 yards. What percent error did Zane make? If a decimal, round the percent to 2 decimal places.
Answer:
Zeke had a 2.17% margin of error in his estimation.
Step-by-step explanation:
To set this problem up, you would need to create a proportion. X, the percent of error you're trying to find, should be over 100%. It should look like:
2/92 = X/100
This would translate your terms, the distance the football was kicked, into percentage terms. You should have 2/92 rather than 90/92. 90/92 would give you how accurate Zeke's estimate was instead of is percent of error.
Cross-multiply your numbers:
(2)(100) = 92X
200 = 92X
X = 2.1739
Then, once you round it, your answer would be X = 2.17.

Step-by-step explanation: I know math just trust me i am a sraight A student.
Not long after he begins to study algebra he will likely meet with the "tank" problems, the "labor" problems and many other puzzle problems. He finds these problems carefully phrased in the language of practical mathematics. However, a study of the original problems and the fanciful way in which they were stated will reveal the fact that they were originally intended mostly for puzzles. The present-day student of algebra would doubtless work as industriously over the so-called practical problems if he were told they were puzzle problems that his predecessors had worked on for the past 1600 years.
The problems given below are selected from a collection made by Metrodorus about 310 A. D. found in The Greek Anthology. It is not known how much farther back they date. It will not be difficult for the reader to trace many of the problems found in the present-day algebras back to their original source. He may judge for himself as to whether the modern text-book writer has improved the problems by leaving off the little fanciful touches of rhetoric, found in the original.
The original problems were solved by rhetorical algebra as our symbols, +, -, ×, ÷, etc., were introduced many centuries later, about 1540.
