What is the scale factor? PLZ HELP
Answer:
1 2/3 aka 1.6666666666666...
Step-by-step explanation:
When you divide 15 by 9 that is the number you get, and you can verify it by then multiplying 9 by 1 2/3 and you get 15. I don't know if they are wanting you so get x, but if they do then you would multiply 6 by the scale factor and you would get 10.

The Skateboard club has 2 different colors of skateboards blue and red. Can you find the number of skateboards of each color, if the total number of skateboards is 15, and their product is 44?
Answer:
The number of skateboards of each color is 11 and 4
Step-by-step explanation:
Let x represent blue skateboards and
y represent red skateboards.
From the question, the total number of skateboards is 15, that is,
x + y = 15 ...... (1)
and their product is 44, that is,
xy = 44 ...... (2)
From equation (1),
x + y = 15
We can write that
x = 15 - y ...... (3)
Substitute this into equation (2)
xy = 44
(15-y)y = 44
15y -y² = 44
Then,
y² - 15y + 44 = 0
Solve quadratically
y² -4y -11y + 44 = 0
y(y-4) -11(y-4) = 0
(y-11)(y-4) = 0
y-11 = 0 OR y-4 = 0
y = 11 OR y = 4
Put the values of y into equation (3) for x
x = 15 - y
When y = 11
x = 15 - 11
x = 4
and when y = 4
x = 15 -4
x = 11
(4,11) and (11,4)
It is either 4 blue and 11 red skateboards OR 11 blue and 4 red skateboards.
Hence, the number of skateboards of each color is 11 and 4.
The graph of y= 3 + 2x -x is shown.
a) What are the coordinates of the turning point? I
b) What are the coordinates of the roots of the equation 3 + 2x - x = 0 ?
Answer:
Step-by-step explanation:
(1, 4)
(-1, 0), (3, 0)
The coordinate of the turning point is (1,4) and the coordinates of the roots are (-1,0) and (3,0)
How to determine the coordinate of the turning point?This is the vertex of the equation.
The equation is the given as:
y = 3 + 2x - x^2
According to the graph, the vertex is at the coordinate (1,4)
Hence, the coordinate of the turning point is (1,4)
How to determine the coordinate of the roots?The equation is the given as:
3 + 2x - x^2 = 0
According to the graph, the equation crosses the x-axis at (-1,0) and (3,0)
Hence, the coordinates of the roots are (-1,0) and (3,0)

The width of a rectangle is x. Its length is 3x. How long is the diagonal of the rectangle? Express your answer in simplified radical form.
Answer:
The length of the diagonal is x√10
Step-by-step explanation:
Here, we want to find the length of the diagonal
The diagonal will represent the hypotenuse of a triangle formed with the width and length of the triangle being the measure of the other sides
Mathematically, we then apply Pythagoras’ theorem to get this
we have this as that the square of the diagonal equals the sum of the squares of the two other sides

The sum of the remaining angles is 180-128 = 52°.
The remaining angles must be 26° each.
In the triangle below, what is the length of the side opposite the 30 degree angle?
Answer:
A. 3/2
Step-by-step explanation:
To find the lenght of the side opposing the 30° angle, you need to use trigonometry, since it's a right-angled triangle. You have your 30° angle and you have the side beside : therefore, you can use the sine :
sin(30) x 3 = ?
0,5 x 3 = ?
1,5 = ?
1,5 = 3/2

Solve for x if EF = 2x + 7 and FG = 7x –9
help please I'll give brainliest
Answer:
x = 3.2
Step-by-step explanation:
Since, intercepts made by parallel lines on the transversals are in proportion.
[tex] \therefore \frac{AB}{BC} =\frac{EF}{FG}... (1)[/tex]
AB = BC.... (given)

The map shows different events at a ski resort. Each unit of the coordinate plane represents 1 mile.
What is the distance between snow tubing and the ski lift?
A. 6 miles
B. 7 miles
C. 13 miles
D. 17 miles
Answer: B
Step-by-step explanation:
Let us write down the coordinates of the snow tubing and the ski lift.
Ski Lift = (3 , -4)
Snow Tubing = (3, 3)
We want to find the distance, which can be found by subtracting their y coordinates from each other.
-4 - 3 = 7

A new bagel store opened. The first day 15 customers entered the store. The number of
customers that enter the store triples each day after. Which function represents f(d), the
number of customers that enter on the d day?
1.
f(d) = 3(15)
2.
f(d) = 3d + 15
3
f(d) = 150 + 3
f(d) = 15(3)
Submit Answer
Answer:
[tex]f(d) = 15 + 3d[/tex]
Step-by-step explanation:
Given
[tex]a = 15[/tex] --- day 1
[tex]Rate = 3[/tex] -- i.e. triples daily
Required
Determine the function f(d)
The number of customers on a particular day is:
Customers = Day 1 + Rate * Number of days
Represent as a function:
[tex]f(d) = a + Rate* d[/tex]
Where d is the number of days.
So, we have:
[tex]f(d) = 15 + 3* d[/tex]
[tex]f(d) = 15 + 3d[/tex]

Answer:
5,720,000 Sq Feet.
Step-by-step explanation:
They are asking the Area of a Trapezoid
Equation =( base + base / 2) x height
Lets first set it up. We know that A-B is 200 feet. & D-C is 260. They are both the bases.
So if you multiply them (200 x 260) You will get 52000.
Now we divide that by 2. (52000 / 2 = 26000)
Now it says the straight line is 220. I think this refers to the height.
Now we multiply 26000 x 220. Which is 5720000.
Its a pretty big number, but that is the answer! :)

Answer:
Distributing
Step-by-step explanation:
The first step is to get the x's out of parenthesis. Distribute the 2 into the (x-4), and the -3 into (x+2).
ex. 2(x-4) = -3(x+2)
distribute: 2x-8= -3x+6

Solve the equation for y. Show work.
6x−4y=24
Answer:
y = -3/2x + 6
Step-by-step explanation:
We won't be able to figure out Y in number form, since we have a second variable, but we can figure it out in terms of X.
First, we have to subtract 6x from both sides
( -4y = -6x + 24 )
Then we have to divide both sides by -4
( y = -3/2x + 6 )
This is our final answer in terms of x

Mei wants to solve the inequality --W < 12. How can she isolate the variable?
2
• Multiply both sides by -2 and reverse the inequality symbol.
• Multiply both sides by -2 and do not reverse the inequality symbol.
*) Divide both sides by 12 and reverse the inequality symbol.
) Divide both sides by 12 and do not reverse the inequality symbol.
Answer:
Multiply both sides by -2 and reverse the inequality symbol.
Step-by-step explanation:
To isolate w, multiply both sides by the reverse of -1/2 (because -1/2*2=1 ), which is -2
When multiplying or dividing by negatives, you must reverse the inequality symbol as well.
To isolate the variable, you multiply both sides by -2 and reverse the inequality symbol.
Isolating variables in inequalityIsolation of variables means making the variable the subject of the formula from the given expression.
Given the inequality expression -1/2 w < 12
To make w the subject of the formula, we will have to multiply both sides by -2 to have;
-1/2 w * -2 > 12 * -2
w > -24
Hence to isolate the variable, you multiply both sides by -2 and reverse the inequality symbol.
