A wise man once said, "500 reduced by 4 times my age is 188." What is his age?
Answer:
125
Step-by-step explanation:
Answer:
He Is 78 Years Old.
Step-by-step explanation:
a = age
Solve for a in 500 - 4a = 188.
Simplify 500−4a=188.
500−4a=188
500+−4a=188
−4a+500=188
Subtract 500 from both sides.
−4a+500−500=188−500
-4a = -312
Divide both sides by -4.
[tex]\frac{-4a}{-4} =\frac{-312}{-4}[/tex]
a = 78
Answer:
He Is 78 Years Old.

Step-by-step explanation:
Vijay missed 12 out of his last 16 free throws. Considering this data, how many of his next 20
free-throw attempts would you expect Vijay to miss?
misses
Answer: 15
Step-by-step explanation: i don’t know
Answer:
15
Step-by-step explanation:
The fraction computed shows that the number of his next 20 free-throw attempts that you expect Vijay to miss is 15.
How to solve the fraction?
From the information given, Vijay missed 12 out of his last 16 free throws. The fraction missed will be:
= 12/16
= 3/4
Therefore, the number of his next 20 free-throw attempts that you expect Vijay to miss will be:
= 3/4 × 20
= 15
Mekala has an MP3 player called the Jumble. The Jumble randomly selects a song for the user to listen to. Mekala's Jumble has 4 techno songs, 2 country songs, and 3 jazz songs on it. Mekala plans to listen to 270 songs.
Answer:
Mekala Jumble has 4 techno songs, 2 country songs, and3 jazz songs on it.
Ratio of techno songs,to country songs,to jazz songs= 4: 2 : 3
Whatever be total number of songs, let the number of techno songs, country songs,and jazz songs be 4 x, 2 x, and 3 x.
Total number of songs that Mekala plans to Listen = 2 70
Then , 4 x + 2 x + 3 x= 270
9 x = 270
Dividing both sides by 9, we get
x = 30
So, Number of techno songs = 4 × 30= 120
Number of techno songs = 2 × 30= 60
Number of jazz songs = 3 × 30= 90
Option (b) b) Close to 60 country songs but probably not exactly 60 country songs ,is true option regarding number of songs listen by Mekala.

1.On field day, the P.E. coach divides the students into two groups, Positives and Negatives. He wants to have the same amount of students of each group on each side of a rope, to play Tug-of-War.
He uses the following expression to figure out how many students of a certain group he still needs to create an even match.
–5 + 20
Evaluate the expression and write the answer below. Write only a number, either positive or negative. No letters
Answer:
-15
Step-by-step explanation:
because -5 + 20 = -15.
The coach needs 15 negative players to join the negative team in order to get 20 players (which would make the teams even)

Michael has $12.50 to buy school supplies. He spends $3.49 at one store for a package of glue sticks, but he still needs to buy 4 pens and a notebook. At the next store, he finds pens for $1.49 each.
Part A
What is the most he can spend of a notebook if he buys the 3 pens?
Part B
On a number line, the solution to Part A would have a circle at __________ that is __________ and the number line would be shaded __________.
Answer: Part A- $ 4.54
Step-by-step explanation:
Answer:
Part A: If he's buying 3 pens he'll have $4.54 left, if he's buying 4, he'll have $3.05 left. I don't really understand what you mean with Part B but I hope this answer and explanation for Part A helps you :D
Step-by-step explanation:
3 Pens situation:
12.50 - 3.49 = 9.01
1.49 (The price of a single pen) x 3= 4.47
9.01- 4.47= 4.54.
.......................................4 Pens situation:
12.50 - 3.49 = 9.01
1.49 (The price of a single pen) x 4= 5.96
9.01- 5.96= 3.05.
If measure FG = 120° and measure EH = 94, what is measure angle EPH?
A) 94
B) 120°
C) 114
D) 107°
Answer:
∠EPH = 107°
Step-by-step explanation:
∠EPH is an angle formed by two intersecting chords.
arc FG and arc EH are the arcs ∠EPH intercepts.
The relationship between an angle formed by intersecting chords and their intercepted arcs is that the angle is equal to half the sum of its intercepted arcs.
Which means that ∠EPH = 1/2 ( arc FG + arc EH )
If arc FG = 120° and arc EH = 94°
Then ∠EPH = 1/2 ( 120 + 94 )
120 + 94 = 214
214 / 2 = 107
Hence, ∠EPH = 107°

For what value of x is line / parallel to line m in this figure?
Answer:
132
Step-by-step explanation:
The angle with a measure of 48 degrees and the angle labeled "x" are supplementary angles. Supplementary angles add up to equal 180
This means that we can find the value of the missing angle by subtracting the measure of the known angle from 180
So x = 180 - 48
180 - 48 = 132
Hence, x = 132

if x + 3/4 =1, then which point on the number line could be x ?
Answer:
point B
Step-by-step explanation:
isolate the x to solve for x:
=> x = 1 - [tex]\frac{3}{4}[/tex]
=> x = [tex]\frac{1}{4}[/tex]
point B=> the half of [tex]\frac{1}{2}[/tex] is [tex]\frac{1}{4}[/tex]=> [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{1}{4}[/tex]

what is the least common multiple of the two denominators 32 18 8 12
Answer:
288
Step-by-step explanation:
32 = 2 × 2 × 2 × 2 × 2
8 = 2 × 2 × 2
18 = 2 × 3 × 3
12 = 2 × 2 × 3
LCM(32, 8, 18, 12)
= 2 × 2 × 2 × 2 × 2 × 3 × 3
= 288

Answer:
229
Step-by-step explanation:
All the angles of a 4 sided shape add up to 360 degrees.
So if you add 99 and 32 together, then subtract the answer from 360, you get 229.
For a 95% confidence interval what would the sample size need to be as it's most conservative to have a 2% margin of error
Answer:
The size of the sample 'n' = 2401
Step-by-step explanation:
Step:1
Given that the margin of error = 2 % = 0.02
The margin of error is determined by
[tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]
we know that the proportion
[tex]\sqrt{p(1-p)} < \frac{1}{2}[/tex]
Step:2
The margin of error is determined by
[tex]0.02 = \frac{1.96( \frac{1}{2} ) }{\sqrt{n} }[/tex]
[tex]\sqrt{n} = \frac{1.96}{2 X 0.02}[/tex]
√n = 49
Squaring on both sides, we get
n = 49 × 49
n = 2401
Final answer:-
The size of the sample 'n' = 2401
the length of a rectangle is twice its width if the perimeter of the rectangle is 72 inches, find its area.
length = 2 x width
permiter = length x width x 2
perimeter = 72
72 ÷ 2 = 36
36 = 1 length and 1 width
(2 x width) + width = 36
width = x
2x + x = 36
3x = 36
x = 12
width = 12
length = 2 x width = 2 x 12 = 24
so
width = 12
length = 24
