Suppose that 13 inches of wire costs 78 cents.
At the same rate, how much (in cents) will 7 inches of wire cost?
Answer:
$0.42
Step-by-step explanation:
create a proportion:
13/.78 = 7/x
cross-multiply to get:
13x = 7(.78)
13x = 5.46
x = 5.46/13
x = .42

The perimeter is about ___
units.
Answer:
18
Step-by-step explanation:
Adding 6 and 3 gives you the full length of the long side of rectangle and since 3 is the radius of the circle, the short side if the rectangle would also be equal to 3.
So, the long sides equal 9 and the short sides are 3, making the perimeter 18
The perimeter of the rectangle is P = 24 units
What is the Perimeter of a Rectangle?The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.
Perimeter P of rectangle = 2 ( Length + Width )
Given data ,
Let the perimeter of the rectangle be P
Now , the width of the rectangle = radius of circle
W = 3 units
And , the length of the rectangle is L = 6 + 3 = 9 units
And , Perimeter P of rectangle = 2 ( Length + Width )
On simplifying , we get
P = 2 ( 9 + 3 )
P = 2 x 12
P = 24 units
Hence , the perimeter is 24 units

Help me ASAP for question 9
Find the unknown angle measures
Answer:
A. 69
C. 42
Step-by-step explanation:
Angle A is similar to angle C, so that makes that angle 69. With two angles figured out, we can just use basic math to find the last.
The total of all triangle angles will always be 180 degrees. Knowing this...
180-69-69=42
Thus, the angles are 69,69, and 42

Find the distance between points P(4, 4) and Q(9, 3) to the nearest tenth
Answer:
[tex]5.1[/tex] units
Step-by-step explanation:
(4, 4) & (9, 3)
To find the distance of two points, we use the distance formula:
[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]
Let's plug in what we know.
[tex]d = \sqrt{(9 - 4)^2 + (3 -4)^2 }[/tex]
Evaluate the parentheses.
[tex]d = \sqrt{(5)^2 + (-1)^2 }[/tex]
Evaluate the exponents.
[tex]d = \sqrt{(25) + (1)}[/tex]
Add.
[tex]d = \sqrt{(26)}[/tex]
Evaluate the square root.
[tex]d = \sqrt{26}[/tex] or [tex]5.0990[/tex] units
Round to the nearest 10th.

Write the equation of the parabola in vertex form.
vertex(2,1),points (1,-4)
F(x)=?
Step-by-step explanation:
The general vertex form is given by
[tex]y = a {(x - h)}^{2} + k[/tex]
where (h, k) is the vertex and a is a constant. So we can write the y as
[tex]y = a {(x - 2)}^{2} + 1[/tex]
To find the value of a, substitute the point (1, -4)
-4 = a(1 - 2)^2 + 1
or a = -5
Therefore, the vertex form of the parabola is
[tex]y = - 5 {(x - 2)}^{2} + 1[/tex]
Mr. Tolin purchased a used car for $2,816, which was 12% off the asking price. What was the asking price of the used car?
Answer:
Original price= $3,200
Step-by-step explanation:
Giving the following information:
Purchase price= $2,816
Discount rate= 12% = 0.12
To calculate the original price, we need to use the following formula:
Original price= purchase price / (1 - discount rate)
Original price= 2,816 / 0.88
Original price= $3,200
