A man earns 12,000 per year, 10% of it was spent on transport while 5% of the salary went as tax. He spent 80% of the remainder on food. How much has he left.
Answer:
Amount left = 2040
Step-by-step explanation:
Given that:
Per year salary = 12,000
Amount spent on transport = 10%
Transport = [tex]\frac{10}{100}*12000[/tex] = 0.1 * 12000
Transport = 1200
Tax = 5%
Tax = 0.05 * 12000
Tax = 600
Total = 1200 + 600 = 1800
Amount left = 12000 - 1800 = 10200
Food = 80% of remainder
Food = 0.8 * 10200
Food = 8160
Amount left after food = 10200 - 8160 = 2040
Hence,
Amount left = 2040

The rectangle on the right is a scaled copy of the rectangle on the left. Identify the
scale factor. Express your answer as a whole number or fraction in simplest form.
Answer:
Scale factor = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Given question is incomplete; find the question in the attachment.
Scale factor = [tex]\frac{\text{Dimension of image}}{\text{Corresponding dimension of preimage}}[/tex]
Scale factor = [tex]\frac{\text{Dimension of image rectangle B}}{\text{Corresponding dimension of preimage rectangle A}}[/tex]
From the figure attached,
Length of rectangle B = [tex]\frac{20}{3}[/tex]
Length of rectangle A = 20
Scale factor = [tex]\frac{\frac{10}{3}}{10}[/tex]
= [tex]\frac{\frac{10}{3}}{10}[/tex]
= [tex]\frac{1}{3}[/tex]
Therefore, image rectangle A is dilated with by a scale factor of [tex]\frac{1}{3}[/tex].

Solve for w: 4w^2+49=-28w
Answer:
Fraction form: -7/2
Decimal form: -3.5
Move all terms to one side
4w^2 + 49 + 28w = 0
Rewrite 4w^2 + 49 + 28w in the form a^2 + 2ab + b^2, where a = 2w and b = 7
(2w)^2 + 2(2w)(7) + 7^2 = 0
Use the Square of Sum: (a + b)^2 = a^2 + 2ab + b^2
(2w + 7)^2 = 0
Take the square root of both sides
3w + 7 = 0
Subtract 7 from both sides
2w = -7
Divide both sides by 2
w = -7/2

On a certain hot summer's day, 386 people used the public swimming pool. The daily prices are $1.75 for children and $2.50 for adults. The receipts for admission totaled $807.50. How many children and how many adults swam at the public pool that day?
Answer:
Call x is childrens
Call y is adults
x + y = 386 (1)
1,75x + 2,5y = 807,5 (2)
(1) => x = 386 - y => (2) 1,75 ( 386-y )+2,5y = 807,5
0,75y=132 => y = 176 and x = 210

John's family visited his grandmother over the weekend. the drive to her house was 2 hours at their usual speed. the trip back took 15 min longer because traffic was bad and they had to drive 5 mph slower. how many miles away is Johns's grandmother's house?
The distance to Johns's grandmother's house is 90 miles.
SpeedSpeed is the ratio of total distance to total time taken, it is given by:
Speed = distance / time
Let x represent the speed that John used and d represent the distance, hence:
x = d/2
Also when taken 15 minute longer (0.25 hours):
x - 5 = d/(2 + 0.25)
x = d/2.25 + 5
Equating:
d/2 = d/2.25 + 5
d = 90 miles
The distance to Johns's grandmother's house is 90 miles.

Stefan sells Jin a bicycle for $138 and a helmet for $16. The total cost for Jin is 40 % of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally?
Answer:
The original cost is
$385
Step-by-step explanation:
Step one:
given data'
cost of bicycle= $138
helmet = $16
Total cost = 138+16= $154
Step two:
let the original cost be x
we are told that 40% of x= 154
hence
40/100*x= 154
0.4x=154
divide both sides by 0.4
x= 154/0.4
x=$385

the water level in Noah's water tank is 72 inches high. Noah begins to drain a water tank by opening a valve. the water drains at the speed of 5 inches per minute. what is the slope?
Answer:
An equation of slope:
y = -5x+72
Step-by-step explanation:
The equation of slope intercept is given by:
where m is the slope and c is the y-intercept or initial value.
Let x represents the time in minutes and y represents the height of the water level
As per the statement:
The water level in Noah's water tank is 72 inches high.
At x = 0
y= 72
It is also given that:
The water drains at a speed up 5 inches per minute.
Here, m represent the slope in inches per minute
(as the water drains)
Substitute in [1] we get;
y = -5x+c
Substitute x = 0 then;
72 = -5(0)+c
72 = c
⇒equation becomes: y = -5x+72
Therefore, an equation of slope is y = -5x+72

Answer:
Step-by-step explanation:
<NOC is 31 because it is a vertical angle to <BOK, which is also 31
<DOC is 62 because it is two times the bisected <NOC. 2*31=62
<DON is 31 because it is the bisected angles <DON and <NOC are equal.
<TOC is 118 because <KOT and <NOC are both 31 degrees. Since they lie on a line together, the three angles should add up to 180 degrees. 180-31-31 = 118
