It is plus five, minus two (repeated)
The pattern is +5 then -2 alternatively .
What is pattern?A pattern is a repeated arrangement of numbers, shapes, colors and so on. The Pattern can be related to any type of event or object. If the set of numbers are related to each other in a specific rule, then the rule or manner is called a pattern. Sometimes, patterns are also known as a sequence.
According to question
7 12 10 15 13 .........
The pattern in the series is
7+5 = 12
12-2 = 10
10+5=15
15-2= 13 .....................
Hence, the pattern is +5 then -2 alternatively .

The time t required to empty a water tank varies inversely as the rate of pumping p. A pump can empty a water tank in 40 min at the rate of 120 gal/min. Write the equation of the inverse variation. How long it will take the pump to empty the water tank at the rate of 200 gal/min?
the question requires:
the time t required.
the equation of the inverse variation.
how do find t:
first we determine how much the tank holds by multiplying 120 by 40.
the tank holds 4800 gallons.
so now to find t we can use the formula v = d/t where d is the 4800 gallons.
so: t = d/v
t = 24 minutes
now for the equation of the inverse variation.
we can say that the equation is t = d/v since t and v are inversely proportional.
note that v and t stand for velocity and time respectively.
make sure to ask if you need any further guidance!!
Answer:
t = 24

Answer:
45.2pi inches
Step-by-step explanation:
C=2×pi×r
since the answers already have pi we don't need to multiply it
C=2×22.6 = 45.2pi inches
Answer:
A. 22.6π
Step-by-step explanation:
Given:
22.6 inches across = diameter
What we need to find is how much ribbon do we need, so we use the formula:
C = 2πr
C = Circumference
r = radius = half diameter
Since we know the diameter, we do half of it to get the radius
22.6 ÷ 2 = 11.3
radius = 11
Now we substitute this into the formula:
C = 2πr
Substitute radius into formula
C = 2π(11.3)
Multiply 2 and 11.3
C = 22.6π
If 1/3 gallon of paint covers 1/6 of a wall, then how many quarts of paint are needed for the entire wall?
Answer:
8 quarts
Step-by-step explanation:
1/3 of a gallon ---1/6 of a wall
x - 1 (all the wall)
x = (1 x 1/3) / 1/6
x = 1/3 / 1/6
x = 6/3
x = 2 gallons
1 gallons - 4 quarts
2 gallons - x
x = (2 x 4) / 1
x = 8 / 1
x = 8 quarts

Latonya was just hired as an engineer for an electric company. she will make a salary of $50,000 a year. how much of latonya's salary will be taxed at the 10 percent rate? how much of latonya's salary will be taxed at the 28 percent rate?
The $5000 will be taxable amount at 10% of Latonya's salary, and $14000 will be taxable amount at 28% of Latonya's salary.
What is the income tax rate?It is defined as the tax rate applied on the solely earned money by a single entity.
Latonya salary per year = $50,000
If Latonya's salary will be taxed at the 10% rate, then she needs to pay tax:
[tex]= $50,000\times10\%[/tex]
[tex]=50000\times \frac{10}{100}[/tex]
[tex]= \$ 5000[/tex]
If Latonya's salary will be taxed at the 28% rate, then she needs to pay tax:
[tex]= \$50,000\times28\%[/tex]
[tex]=50000\times \frac{28}{100}[/tex]
[tex]= \$14000[/tex]
Thus, the $5000 will be taxable amount at 10% of Latonya's salary, and $14000 will be taxable amount at 28% of Latonya's salary.

Step-by-step explanation:
First find the area of the rectangle, which is 4x3 (base x height) the area of the rectangle is 12.
We are given the radius as 2 for the quarter circles, and 2 quarter circles form 1 semicircle, so really we can solve for the area of one semi circle using the formula ( (pi*radius²)/2 ). Plug in the values and you should get 6.28.
Next, you add the area of the figures so 12+6.8 which is equal to 18.8.

A meat-seller sells x kg of ducks at $8.50 per kg and (2x + 5 ) kg of chicken at $3.60 per kg. If he collects a total of $206.40, find the value of x.
Answer:
[tex]x = 12[/tex]
Step-by-step explanation:
1) Set up an equation that involves all of the values; the price and kg of each duck and chicken equating to 206.40.
[tex]8.50(x) + 3.60(2x + 5) = 206.40[/tex]
[tex]8.50x + 7.2x + 18 = 206.40[/tex]
2) Solve it.
[tex]15.7x + 18 = 206.40[/tex]
[tex]15.7x = 206.40 - 18[/tex]
[tex]15.7x = 188.4[/tex]
[tex]x = \frac{188.4}{15.7}[/tex]
[tex]x = 12[/tex]
