Which set of equations has 3, 1 as its solution
Answer:
D.) A and D
Step-by-step explanation:
To find which set of equations has the solution (3,1), you need to identify where on the graph this point lies. Remember, in a point, the first number listed (3) is the "x" value and the second number (1) is the "y" value.
First, look for x = 3. This is the number located on the x-axis (horizontal line).
From this spot, since y = 1, move up 1 unit.
At this point, two lines intersect. These lines are lines A and D.
A shoe making company makes 256 pairs of boots in a day how many pairs of boots do they make in 260 days
Answer:
66560 pairs
Step-by-step explanation:
let the number of pairs of boots the company makes in 260 days = X
1day -----------------256pairs
260days-------------X
cross multiplying
1×X = 260×256
X= 66560
therefore, in 260days, he makes 66560 pairs

By the consideration of direct proportionality, the constant of proportionality for the height of the plant is equal to 3 inches per week.
How to find a constant of proportionality in direct proportional equation
Let x and y the number of weeks and the height of the plant, respectively. Given the consideration of direct proportionality, the height of the plant inasmuch as the number of weeks increases. Then, the constant of proportionality (in inches per week) is found by dividing the height of the plant by the number of the respective week:
k = 18 inches /6 weeks = 15 inches /5 weeks = 12 inches/4 weeks = 3 inches/week

Answer:
Adjacent sides are in the ratio 5 : 12
That means,
Let length = 12x and breadth = 5x
Perimeter = 34
2(l+b) = 34
12x + 5x = 17

For the bottom left corner:
[tex]10^{2} + 6^{2} \\= 100 + 36\\= 136[/tex]
Now, 10 - 6 = 4
136 / 4 = 34
For the top left corner:
[tex]7^{2} + 5^{2} \\= 49 + 25\\= 74[/tex]
Now, 7 - 5 = 2
74 / 2 = 37
For the top right corner:
[tex]8^{2} + 4^{2} \\= 64 + 16\\= 80[/tex]
Now, 8 - 4 = 4
80 / 4 = 20
For the bottom right corner:
[tex]6^{2} + 4^{2} \\= 36 + 16\\= 52[/tex]
Now, 6 - 4 = 2
52 / 2 = 26
Another method:
5×6+7=37
7×6-5=37
6×4+10=34
10×4-6=34
4×3+8=20
8×3-4=20
So, 4×5+6=26
6×5-4=26
Firstly we have to multiply number with smaller number from the both number, then, multiply that constant number with larger number and then subtract smaller number you will get same number, in this with 4 only 5 constant number following this rule 4×5+6=26, 6×5-4=26, if you multiply 4 with 6, then, 4×6+6=30, 6×6-4=32, and with 7, 4×7+6=34, 6×7-4=38. So, 26 is the right answer of this question

4. 44 5/24 watts
whoever answers correctly i will give brainliest.
132/3 = 44
5/8 / 3 = 5/8 x 1/3 =5/24
answer: 4. 44 5/24 watts
Answer:
[tex]\sf 4. \quad 44\frac{5}{24}\:\:watts[/tex]
Step-by-step explanation:
Given information:
3 hard drives are using 132 5/8 wattsTo find the number of watts used per hard drive, divide the total amount of watts by 3.
Convert the mixed number into an improper fraction:
[tex]=\sf 132 \frac{5}{8}[/tex]
[tex]\sf =\dfrac{132 \times 8+5}{8}[/tex]
[tex]\sf =\dfrac{1061}{8}[/tex]
Divide by 3:
[tex]=\sf \dfrac{1061}{8} \div 3[/tex]
[tex]\sf =\dfrac{1061}{8} \times \dfrac{1}{3}[/tex]
[tex]\sf =\dfrac{1061 \times 1}{8 \times 3}[/tex]
[tex]\sf =\dfrac{1061}{24}[/tex]
Convert back into a mixed number:
[tex]\sf =\dfrac{1061}{24}[/tex]
[tex]\sf =\dfrac{1056+5}{24}[/tex]
[tex]\sf =\dfrac{1056}{24}+\dfrac{5}{24}[/tex]
[tex]= \sf 44\frac{5}{24}[/tex]
Therefore, the number of watts used per hard drive is [tex]\sf 44\frac{5}{24}[/tex] watts.
Cullumber company had $170,000 of net income in 2021 when the selling price per unit was $152, the variable costs per unit were $96, and the fixed costs were $574,800. management expects per unit data and total fixed costs to remain the same in 2022. the president of cullumber company is under pressure from stockholders to increase net income by $106,400 in 2022.
The number of units sold in 2021 = 13,300 units.
The number of units that would have to be sold in 2022 to reach the stockholder's desired profit level = 15,200 units.
Assuming that Cullumber company sells the same number of units in 2022 as it did in 2021, the selling price in order to reach the stockholder's desired profit level = $160.
The net income of a company is its profit function, derived by the formula:
Profit = Sales - Cost.
Sales are the product of the number of units sold and per unit selling price.
Cost is the sum of fixed costs and the product of the number of units produced to the variable cost per unit.
Assuming the number of units sold in 2021 to be x,
we can say sales = $152x, and
cost = ${574800 + 96x}.
Therefore, profit = sales - cost,
or, 170000 = 152x - {574800 + 96x},
or, 170000 = 56x - 574800
or, 56x = 574800 + 170000 = 744800,
or, x = 744800/56 = 13300.
Therefore, the number of units sold in 2021 was 13,300.
In 2022, the desired profit = $170,000 + $106,400 = $276,400.
Assuming the number of units sold in 2022 to be n, at the same unit data and fixed cost, we can say that:
Sales = $152n, and
Cost = ${574800 + 96n}.
Therefore, profit sales - cost,
or, 276400 = 152n - {574800 + 96n},
or, 276400 = 56n - 574800,
or, 56n = 574800 + 276400 = 851200,
or, n = 851200/56 = 15200.
Therefore, the number of units sold in 2022 should be 15,200 to reach the desired profit of the stakeholders.
When the number of units sold in 2022 is the same as in 2021, that is, the number of units = 13,300, we assume the per unit selling price to be $P.
Now we can say that,
Sales = $13300P.
Costs = ${574800 + 96*13300} = ${574800 + 1276800} = $1851600.
Therefore, profit = sales - cost,
or, 276400 = 13300P - 1851600,
or, 13300P = 1851600 + 276400 = 2128000,
or, P = 2128000/13300 = 160.
Therefore, the new selling price per unit to reach stockholders' desired profit, assuming the number of units sold in 2022 to be the same as in 2021 is $160.

A circle centered at the origin contains the point
(0, -9). Does (8, √17) also lie on the circle? Explain.
O No, the distance from the center to the point
(8, √17) is not the same as the radius.
O No, the radius of 10 units is different from the
distance from the center to the point
(8, √17).
O Yes, the distance from the origin to the point
(8, √17) is 9 units.
O Yes, the distance from the point (0, -9) to the point
(8, √17) is 9 units.
Approximate value of √17
~4+So the point is (8,4)
As we can see in graph the point is contained by the circle
Hence the distance
√(0-8)²+(9-4)²√8²+5²√89Approximately 9 units
Option D
Answer:
Yes, the distance from the origin to the point (8, √17) is 9 units
Step-by-step explanation:
Equation of a circle
[tex](x-a)^2+(y-b)^2=r^2[/tex]
where:
(a, b) is the centerr is the radiusGiven:
center = (0, 0)r = 9Substitute the given values into the formula to create the equation of the circle:
[tex]\implies (x-0)^2+(y-0)^2=9^2[/tex]
[tex]\implies x^2+y^2=81[/tex]
To find if point [tex]\sf (8, \sqrt{17})[/tex] lies on the circle, substitute x = 8 into the found equation and solve for y:
[tex]\implies 8^2+y^2=81[/tex]
[tex]\implies 64+y^2=81[/tex]
[tex]\implies y^2=81-64[/tex]
[tex]\implies y^2=17[/tex]
[tex]\implies y=\sqrt{17}[/tex]
As y = √17 when x = 8, this proves that point (8, √17) lies on the circle.
The distance from the origin to any point on the circle is the radius.
Therefore, as the radius is 9 units, the distance from the origin to the point (8, √17) is 9 units.

Answer:
f(x) = 7.5x
Step-by-step explanation:
you can find the slope by using the slope formula (y2-y1)/(x2-x1). you can use any of the values but for this example I'll be using (2, 15) and (4, 30).
(30-15)/(4-2) = 15/2 = 7.5.
now we can use one of the coordinates to find the y-intercept by plugging the known values in the equation y=mx+b where m is the slope and b is the y-intercept.
for this example I'll be using (2, 15) but you could use any of the values you gave.
15 = 7.5(2) + b
15 = 15 + b
0 = b
so now we have the function rule
f(x) = 7.5x + 0 or just f(x) = 7.5x

Today’s weather map shows the jet stream flowing west to east toward Washington, D.C., at a speed of 70 knots. If the ground speed needs to be 450 knots to make it from Washington to Kansas City on time, what does the plane’s speed need to be?
Considering the direction of the wind, it is found that the plane's speed needs to be of 520 knots.
What is the ground speed?The ground speed, considering that the wind is flowing from Kansas City to Washington, and the trip is Washington to Kansas City, is given by:
