Answer:
76
Step-by-step explanation:
For some common difference d, the terms of the progression are ...
k = 3 +d
w = k +d = 3 +2d
18 = w +d = 3 +3d
Solving for d, we get ...
15 = 3d . . . . subtract 3
5 = d . . . . . . divide by 3
Now, we can find ...
3k +4w = 3(3 +d) +4(3 +2d) = 9 +3d +12 +8d = 21 +11d
3k +4w = 21 +11(5) . . . . substitute for d
3k +4w = 76

A property sells for $140,000 two years after it was purchased. If the annual appreciation rate is 6%, how much did the original buyer pay for it?
Answer:
$123,200
Step-by-step explanation:
0.06 x 2 = 0.12
140,000 x 0.12 = 16,800
140,000 - 16,800 = 123,200
The original buyer paid the amount of $123,200 for the property.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
The property appreciated by 6% per year, so in two years it would have appreciated by 6% × 2 years = 12%.
Once we know the total appreciation, we can subtract that value from 100% to find the original purchase price as a percentage of the final sale price.
If the property appreciated by 12%, then the original purchase price must have been 100% - 12% = 88% of the final sale price.
Now, multiply the final sale price by the original purchase price as a percentage to find the original purchase price.
So, the original buyer paid the amount = 88% × $140,000 = $123,200
Therefore, the original purchase price was $123,200.

Draw a line segment of length 6.4 cm and divide it in to 4 equal parts. Write the length of each part. (Draw clearly)
Answer:
The line drawn has a length of 6.4 cm.
Also it is divided into 4 equal parts.
Hence let the measure of the each equal part be ' x '
So x * 4 parts = 6.4 cm
=> x = 6.4 cm / 4
=> x = 1.6 cm
Hence the measure of each equal part is 1.6 cm.
Hence solved !

Answer:
it is correct
Step-by-step explanation:
2000 N
The resistance force acting is 1N per ton.
Tension in the coupling between engine and the wagon is 2000N.
Answer:
46 will be converted to .44m
x will be the mass of the 44 cm engine
x/72 = .44^3/11^3
x/72 = 0.085/1331
cross multiply
1331x = 72 x 0.085
1331x = 6.12
x= 6.12/1331
=0.004598
x = 0.004598 tonnes
change to kilograms
0.004598*1000 = 4.6 kg

For what value(s) of x is f(x)=3?
Answer:
D
Step-by-step explanation:
Remember that for this kind of question, when f(x) is given as 3, then 3 is the y value of the point. So you must have a point whose value is (x,3)
There is only one point that does that. x = - 2
The answer is D
The diameter of a circle is 19 7/8". What is the circumference (to 2 decimal places)?
Please note:
C = πd
Answer:
62.41
Step-by-step explanation:
19 7/8= 19.875
C= pie x d
C= 3.14 x 19.875
C= 62.4075
C= 62.41 (if you want 2 decimal places)

Saji swims 1/3 mi every day. One day he had already swum 1/5 mi. How much further should he swim?
9514 1404 393
Answer:
2/15 mi
Step-by-step explanation:
The difference of two fractions can always be computed using the pattern ...
[tex]\dfrac{a}{b}-\dfrac{c}{d}=\dfrac{ad-bd}{bd}[/tex]
Using this pattern to find the difference of 1/3 and 1/5, we see it is ...
1/3 -1/5 = (5 -3)/(3·5) = 2/15
Saji must swim 2/15 miles further to complete his 1/3 mile swim.

A falcon flies 300 kilometers per hour. A goose flies 140 kilometers per hour. If a falcon and a goose each fly for 2 hours, how many more kilometers will a falcon fly?
Answer:
320
Step-by-step explanation:
Distance covered by falcon in 2 hours=300*2=600 km
Distance covered by goose in 2 hours=140*2=280 km.
Falcon flew 600-280=320 km more than goose

Answer:
C(x) = x/11 + 34 6/11
Step-by-step explanation:
The two given points are (x, C) = (60, 40) and (170, 50). These can be used in the 2-point form of the equation for a line to find the cost function.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (50 -40)/(170 -60)(x -60) +40
y = (1/11)(x -60) +40
C(x) = 1/11x +34 6/11 . . . . . . cost as a function of copies made
the line y=mx+7 is perpendicular to the line y=3/4x-9. what is the value of m?
Answer:
-4/3
Step-by-step explanation:
In y=mx+b, m represents the slope. In the second line, we are multiplying x by (3/4). This represents the slope of the second line.
To find the slope of a perpendicular line, we take the negative reciprocal of the current slope. In the first line, m represents the slope. The reciprocal of 3/4 is 4/3, and the negative reciprocal of 3/4 is -4/3. This is the value of m
Is 10 irrational or rational
Answer:
Rational
Step-by-step explanation:
An irrational number is a number that goes on forever, such as pi. These numbers have infinite decimals.
In contrast, a rational number is a number that can be created by dividing two other integers.
These numbers do not go on forever.
10 is a rational number because it can be created by dividing 2 other integers, and it does not go on forever.

Ronnie sales wooden toothpicks it cost him $.10 to make a box of toothpicks he charges $1.20 per box toothpicks how many toothpicks does he need to sell to profit $1000
Answer:
910 boxes of toothpicks
Step-by-step explanation:
Create an equation to represent the situation, and let x represent the number of boxes of toothpicks.
1.20x - 0.1x = 1000
1.1x = 1000
x = 909.09
Round up to the nearest whole number:
= 910
So, Ronnie would have to sell 910 boxes of toothpicks to profit $1000.
