The number of pounds of peaches is 6 pounds and the number of pounds of apples is 18 pounds
Given:
cost of peaches per pound = $4
cost of apples per pound = $2
Total amount spent = $60
Total pounds bought = 24
let
x = number of peaches
y = number of apples
x + y = 24 (1)
4x + 2y = 60 (2)
multiply (1) by 2
2x + 2y = 48 (3)
4x + 2y = 60 (2)
subtract (3) from (2)
4x - 2x = 60 - 48
2x = 12
x = 12/2
x = 6
substitute x = 6 into (1)
x + y = 24 (1)
6 + y = 24
y = 24 - 6
y = 18
Therefore, the number of pounds of peaches is 6 pounds and the number of pounds of apples is 18 pounds

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.

Two numbers whose sum is 29 and their difference is 15
Answer:
22 and 7
Step-by-step explanation:
Let x and y be the two numbers we are looking for:
The statement “their sum is 29” means x + y = 29
The statement “their difference is 15” means x - y = 15
we get this system:
x + y = 29 (1)
x - y = 15 (2)
Let’s solve it :
(1) + (2) ⇒ x + y + x - y = 29 + 15 ⇒ 2x = 44 ⇒ x = 44/2 = 22
Now we replace x by 22 in equation (1) :
22 + y = 29 ⇒ y = 29 - 22 = 7
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]

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

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.

which is an equation of the axis of symmetry of the graph of the equation y= x^2-6x+2?
1) x=-3
2) y=-3
3) x=3
4) y=3
Answer:
x=3
Step-by-step explanation:
The equation is written in the form ax2+bx+c. As you can see, a=1, b=-6 and c=2. The axis of symmetry is worked out by x=−b2a.
−(−6)2(1) = 62=3
Substituted this value of x back into the equation to find the y coordinate.
y=(3)2−6(3)+2
y=9−18+2
y=−7q

Q.1. The potter at a pottery store makes two sizes of vases. The larger size takes six hours to make, and the smaller size takes 1.5 hours to make. The potter works 30 hours a week. She needs to make at least six total vases a week, including at least two of each size. Give one example of how many of each type of vase the potter can make.
Answer:
Step-by-step explanation:
Let x and y be the large (x) and small (y) vases the potter makes in one week.
We are told that the large and small vases require 6 hours for each large(x) and 1.5 hours for each small (y) vase. The combination of large and small vases made in one week thus requires a total time of:
6x + 1.5y = total hours/week
We are told that the potter works 30 hours per week, so:
6x + 1.5y = 30 hours
We also learn that she needs to make at least 6 vases in a week, so:
x + y => 6
Plot the two equations:
6x + 1.5y = 30, and
x + y => 6
This will produce the attached grap, Vases1. The inequality appears as the shaded area in the upper area. Any point in the shaded area satisfies the inequality of x + y => 6. The x and y intercepts are at (0,6) and (6,0), representing either all large (x) or small vases (y).
The lines intersect at (4.67,1.33). This represents a fictional combination of 4.67 large and 1.33 small vases. This results in 6 vases (4.67 + 1.33) that require a total of 30 hours to make (6*4.67 + 1.5*1.33) = 30 hours. If you want to select whole number answers, they appear at (0,6), (2,4), (4,2), and (6,0). (x,y or large,small). All combinations result in 6 vases, but eould require less than the 30 hours of time available. Any whole number combination in the area below the line 6x + 1.5y = 30, but above the line x+y =>6 are valid, such as (4,4). This area is shown in Vases2. The valid area for making choices has the darkest shade, where the two inequalities are both satisfied.
Liana started to evaluate the function f(x) = 2x2 – 3x 7 for the input value 2. f(x) = 2(2)2 – 3(2) 7 = 2(4) – 3(2) 7 what is the value of the function when x = 2? 9 10 16 17
The value of the function when x = 2 will be 9. The value is obtained by putting the value 2 in the place of x.
What is a function?A connection between independent variables and the dependent variable.is defined by the function. Functions help to represent graphs and equations.
The given function in the problem is;
[tex]\rm f(x) = 2x^2 - 3x + 7[/tex]
On putting x =2 we get;
[tex]\rm f(2) = 2(2)^2 - 3(2) + 7 \\\\\ f(2) = 2(4) - 3(2) + 7 \\\\ f(2) = 8 - 6 + 7 \\\\ f(2) = 9[/tex]
