Answer:

I DONT KNOW

Step-by-step explanation:

Figure it out

Let c represent amount of commission and s represent amount of sales.

We have been given that Lee sells electronics. He earns a 5% commission on each sale he makes.

A. We are asked to find the constant of proportionality.

First of all, we will write our given equation as direct proportion. We know that two proportional quantities are in form [tex]y=kx[/tex], where y is directly proportional to x and k represents constant of proportionality.

We can represent our given information in an equation as:

[tex]c=\frac{5}{100}s[/tex]

[tex]c=0.05s[/tex]

Therefore, constant of proportionality is [tex]0.05[/tex].

B. To find amount of electronics sold by Lee, we will substitute [tex]c=100[/tex] in our equation an solve for s as:

[tex]100=0.05s[/tex]

[tex]\frac{100}{0.05}=\frac{0.05s}{0.05}[/tex]

[tex]2000=s[/tex]

Therefore, Lee must sell $2000 of electronics to make $100 commission.

Answer:

Step-by-step explanation:

+ Because of " the line passing through the points (-2, 2) and (3,-1)", that means this line has its equation y = ax + b where

[tex]a=\frac{2-(-1)}{-2-3} =\frac{2+1}{-5} =-\frac{3}{5}[/tex]

So we write its equation: y = -3/5 x + b.

+ Then, now, we replace x = -2 and y = 2 into y = -3/5 x + b for finding b like:

2 = -3/5 * (-2) + b or 2 = 6/5 + b

so b = 2 - 6/5 = 4/5.

And this line has its equation: y = -3/5 x  + 4/5.

Mẹthod 2:

we have a formule for a line that passes 2 points [tex](x_{0},y_{0}) , (x_{1},y_{1}) ,x_{0}\neq x_{1}[/tex]

Here is: [tex]\frac{x-x_{0} }{x_{1}-x_{0} } = \frac{y-y_{0} }{y_{1}-y_{0} }[/tex]

Then, we can write for this case:

[tex]\frac{x-(-2)}{3-(-2)} =\frac{y-2}{-1-2} \\\frac{x+2}{5} =\frac{y-2}{-3} \\-3(x+2) = 5( y-2)\\-3x-6=5y-10\\3x+5y-4=0\\or\\y=-\frac{3}{5}x+\frac{4}{3}[/tex]

Answer:

If the coefficient of the squared term is positive, the parabola opens up. The vertex of this parabola is called the minimum point. If the coefficient of the squared term is negative, the parabola opens down. The vertex of this parabola is called the maximum point.

The graph opens upward, if the vertex of the quadratic function with a positive a value.

Given that, the quadratic function with a positive a value.

The vertex of the graph of a quadratic function is the highest or lowest possible output for that function. If you're looking at a graph, the vertex would be the highest or lowest point on the parabola. The easiest way to find the vertex is to use the vertex formula.

If a is positive, the graph opens upward, and if a is negative, then it opens downward. The line of symmetry is the vertical line x = h, and the vertex is the point (h, k). Any quadratic function can be rewritten in standard form by completing the square.

Therefore, the graph opens upward, if the vertex of the quadratic function with a positive a value.

He stopped at 11:35 P.M

=> He practiced in 35 - 15 = 20 mins = 1/3 hour.

=> 1/3 hour means 1/3 circle, the number of degrees the minute hand turned:

N = (1/3) x 360 = 120 deg (1 circle = 360 deg)

Answer:

The other angle is 110

Step-by-step explanation:

Supplementary angles add to 180

Let x be the other angle

70+x = 180

Subtract 70 from each side

70+x-70 = 180-70

x = 110

Answer:

About 7.8 miles.

Step-by-step explanation:

We can use the distance formula to find the distance from the gas station to the house.

However, your teacher said to use the Pythagorean Theorem to find the distance.

(4,3), (10,8), and (10,3) would make a right triangle.

[See Picture]

Angelica's house is at point (4,3). It is 6 units from our new third point.

The gas station is at point (10,8). It is 5 units form out new third point.

The legs are 5 and 6 units. The distance from the house to the gas station would be our hypotenuse.

Use the Pythagorean Theorem to find the length of the hypotenuse.

[tex]a^2 + b^2 = c^2\\\\\text {Replace a and b with the appropriate values: }\\6^2 + 5^2 = c^2\\\text {Solve: }\\6^2 + 5^2 = c^2\\6^2 = 36\\5^2 = 25\\\rightarrow 36 + 25 =c^2\\36 + 25 = 61\\\rightarrow 61=c^2\\\sqrt{61}=\sqrt{c} \\\boxed {7.81024967591=c}[/tex]

7.81024967591 ≈ 7.8

The hypotenuse is about 7.8.

Therefore, the distance between the gas station and Angelica's house should be about 7.8 miles.

Answer:

AG = 7,8

Step-by-step explanation:

Plot the third point at (10,3) and let's call it point B.

Now construct the right sided triangle A B G

With A = (4,3) , B = (10,3) and G = (10,8).

AB is horizontal so subtract the x coordinates of point A and point B. So AB has length 10 - 4 = 6

BG is vertical so subtract the y coordinates of point B and point G. So BG has length 8 - 3 = 5

Now use pythagorean theorem to calculate AG

In any right sided triangle you can use a² + b² = c²

In our case AB² + BG² = AG²

Substitute AB = 6 and BG = 5

6² + 5² = AG²

AG² = 6*6 + 5*5

AG² = 36 + 25

AG = + - SQRT(61)

{Only the + variant of the SQRT has a meaning here.}

AG = 7,81 rounded on one decimal AG = 7,8

Got it right on the test ✅

Answer:

easy peasy,

the 'n' th term of any arithmetic sequence can be found with the following formula

=> a + ( n-1) d, [where 'a' if the first term of the sequence, 'n' the number of term we need to find, and 'd' being the common difference between each two consecutive term of the sequence)

all in this case would be,

a = 0

n = 100

d = +5

hence the 100th term would be,

=>  0 + (100 - 1) 5

=> 99 x 5

=> 495

Answer:

Interval for the function has local minimum of 0 is [2,4].

Step-by-step explanation:

You need to find the local minimum of 0 in the given function's graph.

In mathematics, local minimum is a point on a graph whose value is less than all other points near it.

See that, graph value 0 is lie on the x = 3 and in interval x = 2 to x = 4

So, final answer is :

Interval for the function has local minimum of 0 is [2,4].That's the final answer.

Answer:

X intercept is (-8,0), Y intercept is (-6,0)

Step-by-step explanation:

The intercept is where the line crosses the X and Y axis, so in this line, the line crosses the x axis at (-8,0) and the y axis at (-6,0).

Answer:

There are two different intercepts in this linear line. The x - intercept would be at (-8, 0), and the y - intercept would be at (0,-6). To find out which is the x - intercept and which is the y - intercept, remember that x is always horizontal and y is always vertical.

Area = 1/2 x base x height

Answer:

24cm²

Step-by-step explanation:

So you do 8×4=48 (a square) then half it (triangle) which becomes 24cm²

Well, a simple way to do it is to do base × height then half it

Answer:

i think its 25 because like if 72 is the shaded part then it can't be the answer 100 wouldn't be the answer because it is too high and 20 wouldn't be the answer because it is too low so 25 is my reasonable answer.

Step-by-step explanation:

Since the area to me is 25 then we would do 360 x 25 = 9000

the you do 9000 / 36 i got 36 by doing 360 / 10

After that you you do 9000 / 36 which gives you 2.5

Last i did 2.5 x 10 which gave me 25

Answer:

ask your math teacher i rember learning this but froget ow

Step-by-step explanation:

Write equations with j own information:

Adult + child = 200

Adult = 200 - child

3.00 Adult + 1.50 child = 510

Combine equations:

3.00(200-child) + 1.50 child = 510

Simplify:

600 -3.00 child + 1.50 child = 510

600 - 1.50 child = 510

Subtract 600 from both sides:

-1.50 child = -90

Divide both sides by -1.50

Child = -90 / -1.50

Child = 60

There were 60 child seats sold and 140 adult seats sold.

Answer:

The sum of the inverses of two rational numbers is 5 by 6, and the difference of the inverses of the numbers is 1 by 6. Calculate the sum and product of numbers.

Sum = a + b = 5

Product = a ₓ b = 6

Step-by-step explanation:

[tex]\frac{1}{a} +\frac{1}{b} =\frac{5}{6}[/tex]

[tex]\frac{1}{a} -\frac{1}{b} =\frac{1}{6}[/tex]

Add both equations together

[tex]\frac{1}{a} +\frac{1}{a} +\frac{1}{b} -\frac{a}{b} =\frac{5}{6} +\frac{1}{6}[/tex]

2 / a = 6/6

2 / a = 1

a = 2

we replace in any relation a

1 / 2 + 1 / b = 5 / 6

3b + 6 = 5b

5b - 3b = 6

2b = 6

b = 3

Sum = a + b = 2 + 3 = 5

Product = a ₓ b = 2 ₓ 3 = 6

Answer:

Multiply (2 * 16)

Step-by-step explanation:

Our expression is 13 - 2 * 16 + 2. The two operations used here are addition (+) and multiplication (*).

Remember order of operations PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

We see that multiplication comes before addition, so we multiply 2 by 16 first:

13 - 2 * 16 + 2

13 - 32 + 2

Thus, the answer is multiply.
