The commission that the salesperson earns on the sale is $1320

The commission would be double when he doubles his sales of furnaces

Step-by-step explanation:

The given is:

We need to find the commission that the salesperson earns

∵ The salesperson earns 4% commission on furnaces sale

∵ The furnaces sale have worth $33,000

- Find the 4% of 33,000

∴ The salesperson earns 4% of 33,000

∵ 4% × 33,000 = [tex]\frac{4}{100}[/tex] × 33,000 = 1320

∴ The salesperson earns $1320

The commission that the salesperson earns on the sale is $1320

∵ The salesperson doubles his sales of furnaces

∴ The commission would be double

That because the commission is a constant percent from his sales of furnaces, so if the amount of his sales of furnaces doubles , then his commission also doubles, it is a direct proportion relationship

Commission = constant (4%) × amount of furnaces sale

The commission would be double when he doubles his sales of furnaces

Answer:

Sum of the solutions of [tex]x^2+9x+20=0[/tex] is -9.

Product of the solutions of [tex]6x^2+7x=3[/tex] is [tex]-0.50[/tex]

Step-by-step explanation:

1. [tex]x^2+9x+20=0[/tex]

Given:

The expression whose sum of the solution is required is given as:

[tex]x^{2} +9x+20=0[/tex]

For a quadratic equation of the form [tex]ax^2+bx+c=0[/tex] the sum of the solutions is given as:

Sum = [tex]\frac{-b}{a}[/tex]

Here, [tex]a=1,b=9,c=20[/tex]

Therefore, the sum of the solutions = [tex]-\frac{9}{1}=-9[/tex]

2. [tex]6x^2+7x=3[/tex]

Rewriting the above equation in a standard quadratic equation, we get:

[tex]6x^2+7x-3=0[/tex]

For a quadratic equation of the form [tex]ax^2+bx+c=0[/tex] the product of the solutions is given as:

Product = [tex]\frac{c}{a}[/tex]

Here, [tex]a=6,b=7,c=-3[/tex]

Therefore, the product of the solutions = [tex]\frac{-3}{6}=-0.50[/tex]

The total cost of all the pizzas that the softball team order can be calculated as 6c + 10f, where c represents the number of cheese pizzas ordered, and f represents the number of four-topping pizzas ordered.

To determine how much the softball team is spending on pizzas, we need to multiply the cost of each type of pizza by the number of each type they are ordering. For the cheese pizzas, that cost $6 each, the cost will be:
6c (where 'c' is the number of cheese pizzas).
For the four-topping pizzas, that cost $10 each:
The cost will be 10f (where 'f' is the number of four-topping pizzas).

Now, to calculate the total cost, we add up the cost of the cheese pizzas and the four-topping pizzas:
Total cost = 6c + 10f

Answer:

Part a) m∠WZY=72°

Part b) m∠XWZ=108°

Part c) m∠WYZ=28°

Step-by-step explanation:

we know that

In a parallelogram opposite angles are congruent and consecutive angles are supplementary

see the attached figure to better understand the problem

Part a) Find the measure of angle WZY

we know that

m∠WZY≅m∠WXY ----> by opposite angles

we have

m∠WXY=72°

therefore

m∠WZY=72°

Part b) Find the measure of angle XWZ

we know that

m∠XWZ+m∠WXY=180° ----> by consecutive angles

we have

m∠WXY=72°

substitute

m∠XWZ+72°=180°

m∠XWZ=180°-72°

m∠XWZ=108°

Part c) Find the measure of angle WYZ

we know that

The sum of the interior angles of a triangle must be equal to 180 degrees

In the triangle WZY

m∠ZWY+m∠WZY+m∠WYZ=180°

we have

m∠ZWY=80°

m∠WZY=72°

substitute

80°+72°+m∠WYZ=180°

152°+m∠WYZ=180°

m∠WYZ=180°-152°

m∠WYZ=28°

In a parallelogram, finding angles involves rules like opposite angles being equal and adjacent angles being supplementary. wzy = 72 degrees, xwzc = 80 degrees, and wyz = 108 degrees.

Given:

wxy = 72 degrees

zwy = 80 degrees

To find:

wzy: Opposite angles in a parallelogram are equal, so wzy = wxy = 72 degrees

xwzc: Opposite angles in a parallelogram are equal, so xwzc = zwy = 80 degrees

wyz: Adjacent angles in a parallelogram are supplementary. Therefore, wyz = 180 - wxy = 180 - 72 = 108 degrees

Answer:

12 days

Step-by-step explanation:

At the end of the first day he has the distance left to climb = 5,250 feet

He plans to climb the distance each day = 500 feet

Number of days to complete his trip = [tex]\frac{5,250}{500}[/tex]

                                                             = 10.5 ≈ 11 days

He has already climbed for one day, so he will finish his trip in 1 + 11  = 12 days.

Answer:

Megan is 14

Step-by-step explanation:

Megan is M

Molly is Mo

Mo = 8

M = x

6 + mo = x

6 + 8 = 14

If Molly is 8 years old and there is a 6-year age gap between her and Megan, then Megan must be 6 years older than Molly.

Therefore, Megan is 8 + 6 = 14 years old.

This age gap of 6 years means that Megan was born 6 years before Molly.

Age gaps are calculated by subtracting the younger person's age from the older person's age.

It's important to note that Megan is the older of the two, and the age difference remains constant as they both get older.

Understanding age differences is essential in various contexts, from family dynamics to social relationships and legal matters.

In this case, it's a straightforward calculation, but age gaps can have significant implications in more complex situations, such as legal age requirements, generational differences, and even compatibility in personal relationships.

In this instance, Megan is 6 years older than Molly, and that age gap will remain consistent as they both grow older.

Least possible sum of missing digits is 3 that is 3 + 0 and missing numbers are 30

Solution:

Given that number 42,__2 rounded to the hundred place is 42300 .

Need to determine least possible sum of the two missing digits.

first lets see what all numbers can be rounded to 300  

number from 251 to 349 can be rounded to 300 as 251 is more close to 300 than 200 and 349 is closer to 300 than 400.  

But in our case at ones place we are having 2 , so possible numbers having 2 at ones place and in between  251 to 349 are 252 , 262 , 272 , 282 , 292 , 302 , 312 , 322 , 332  and 342.

but we are only concern numbers at hundred and tens place

so now we have 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 and 34.  

Out of this set we want numbers whose sum is least . So if you carefull observer that number is  30 having least sum as 3 + 0 = 3 .

So missing numbers in 42,__2 is 30 and number is 42,302.

Hence we can conclude that least possible sum of missing digits is 3 that is 3 + 0 and missing numbers are 30.

The solution of the system of equations is (6 , -7)

Step-by-step explanation:

There are two method to solve the system of equations

Let us use the elimination method with your problem

∵ 3x + 2y = 4 ⇒ (1)

∵ 3x + 6y = -24 ⇒ (2)

- Multiply equation (1) by -1 to eliminate x ⇒ to make the coefficients of x in the two equations have same values and different signs

∵ -3x - 2y = -4 ⇒ (3)

- Add equations (2) and (3)

∴ 4y = -28

- Divide both sides by 4

∴ y = -7

Substitute value of y in equations (1) OR (2) to find x

∵ 3x + 2(-7) = 4

∴ 3x - 14 = 4

- Add 14 for both sides

∴ 3x = 18

- Divide both sides by 3

∴ x = 6

The solution of the system of equations is (6 , -7)

Answer:

resistance is 1.5 ohms (1.5 Ω)

Step-by-step explanation:

R varies directly with l

R varies inversely with [tex]d^2[/tex]

We can set-up a proportionality statement as shown below:

[tex]R=k\frac{l}{d^2}[/tex]

Now, Given,

R = 1.50

l = 2

d = 1.5

We substitute and find k (the proportionality constant):

[tex]R=k\frac{l}{d^2}\\1.5=k\frac{2}{1.5^2}\\1.5=\frac{2k}{2.25}\\2k=1.5*2.25\\2k=3.375\\k=1.6875[/tex]

Now, we will use this value of k to solve the problem.

Given,

l = 8

d = 3

and

k = 1.6875

We find R:

[tex]R=k\frac{l}{d^2}\\R=1.6875\frac{8}{3^2}\\R=\frac{1.6875*8}{9}\\R=1.5[/tex]

Equation in slope-intercept form of the line that passes through (6,-2) and (12,1) is:

[tex]y =\frac{1}{2}x-5[/tex]

Step-by-step explanation:

Given points are:

(x1,y1) = (6,-2)

(x2,y2) = (12,1)

The slope intercept form is:

[tex]y=mx+b[/tex]

We have to find the slope first

[tex]m =\frac{y_2-y_1}{x_2-x_1}\\=\frac{1-(-2)}{12-6}\\= \frac{1+2}{6}\\=\frac{3}{6}\\=\frac{1}{2}[/tex]

Putting the value of slope

[tex]y = \frac{1}{2}x+b[/tex]

To find the value of b, putting (12,1) in the equation

[tex]1 = \frac{1}{2}(12)+b\\1 = 6+b\\b = 1-6\\b=-5[/tex]

Putting the values of m and b

[tex]y =\frac{1}{2}x-5[/tex]

Hence,

To write the equation in slope-intercept form, find the slope and y-intercept using the given points. The slope is 1/2, and the y-intercept is -5. The equation is y = (1/2)x - 5.

To write an equation in slope-intercept form, we need to find the slope (m) and the y-intercept (b). The slope can be calculated using the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of two points on the line. In this case, the slope is (1 - (-2)) / (12 - 6) = 3/6 = 1/2.

Now, we can use the slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept. Plugging in the values, we get y = (1/2)x + b.

To find the value of b, we can substitute the coordinates of one of the given points (6, -2) into the equation. -2 = (1/2)(6) + b. Solving for b, we get b = -2 - 3 = -5.

Therefore, the equation in slope-intercept form of the line that passes through (6, -2) and (12, 1) is y = (1/2)x - 5.

Answer:

232.6 metres after 3.8 seconds.

Step-by-step explanation:

h(t) = -16t² + 122t

a = -16  b = 122  c = 0

Substitute into the quadratic formula

(Ignore the Â)

[tex]x =  \frac{-b±\sqrt{b^{2}-4ac}}{2a} [/tex]

[tex]x =  \frac{-122±\sqrt{122^{2}-4(-16)(0)}}{2(-16)} [/tex]

[tex]x =  \frac{-122±122}{-32} [/tex]

Split the equation at the ±

[tex]x =  \frac{-122+122}{-32}[/tex]        [tex]x =  \frac{-122-122}{-32} [/tex]

[tex]x =  \frac{0}{-32}[/tex]                    [tex]x =  \frac{-244}{-32} [/tex]

[tex]x = 0[/tex]                                       [tex]x = \frac{61}{8}[/tex]

The two x-intercepts at 0 and 61/8. The midpoint of the x-intercepts is the axis of symmetry, which is the x-coordinate of the vertex.

Midpoint = [0 + (61/8)] / 2

Midpoint = 61/16   <= This is the time for maximum height

t = 61/16

t = 3.8125  => Round to t = 3.8

To find the maximum height, substitute t=61/16 into the equation

h(t) = -16t² + 122t

h(61/16) = -16(61/16)² + 122(61/16)

h(61/16) = 232.5625  => Round to h = 232.6

Therefore, the ball will reach the maximum height of 232.6 metres after 3.8 seconds.
