Christine drives her car 144 miles and has an average of a certain speed. If the average speed has been 5 mph more, she could have traveled 168 miles in the same length of time. What was her average speed?
Let's make a system of equations:
144/x=y
168/(x+5)=y
So,
144/x=168/(x+5)
Solving using cross multiplication,
x=30
So, her average speed for driving 144 miles was 30 miles per hour.

Answer:
x = 124.5
Step-by-step explanation:
adjacent given 88 and asked us to find x, which is a hypotenuse.
using the cosine formula:
[tex]\frac{adjacent}{hypotenuse} = cos(y)[/tex]
[tex]\frac{88}{hypotenuse} = cos(45)[/tex]
[tex]hypotenuse = \frac{88}{cos(45)}[/tex]
[tex]hypotenuse = 124.5[/tex]
is 17.8 = 18.8 reasonable explain.
Answer:
No.
Step-by-step explanation:
For there to be a equal sign, it will mean that both sides will have to have the same exact amount. If it is expressions on both sides, then the expressions must, when combined, equal to each other.
In this case, there is not given operation that will allow for both numbers to equal each other, and 17.8 is 10 less than 18.8, therefore it is not reasonable.
17.8 ≠ 18.8

Suppose the length and the width of the sandbox are doubled.
the width is 6ft and the length is 10ft
a. Find the percent of change in the perimeter.
The percent of change in the perimeter is a
( %) increase.
b. Find the percent of change in the area.
The percent of change in the area is a
( %) increase.
Answer:
Rectangle is the closed shaped polygon with 4 sides. Opposite sides of the rectangle are equal. when the length and the width of the sandbox are doubled the percent of change in the perimeter is 100 percent and the percent of change in the area is 300 percent.Given-The length of the sandbox is 10.The width of the sandbox is 6.a) The percent of change in the perimeter.Perimeter of the rectangleThe perimeter of the rectangle is the twice of the sum of its side.The perimeter P of the sandbox is,When the length and the width of the sandbox are doubled the perimeter of the box is,Percentage change in the perimeter,b) The percent of change in the area.Area of the rectangleThe area of the rectangle is the product of its side.The area A of the sandbox is,When the length and the width of the sandbox are doubled the area of the box is,Percentage change in the area,Thus when the length and the width of the sandbox are doubled the percent of change in the perimeter is 100 percent and the percent of change in the area is 300 percent.

The area of a trapezoid is 48 square centimeters. The height is 6 centimeters and one base 3 times the length of the other base. What are the lengths of the bases?
The lengths of the bases are: 4cm and 12cm.
Area of a TrapezoidSince the area of a trapezoid is given by the formula;
A = 1/2 (a + b) h.Where a and b are the lengths of the bases and h is the height of the trapezoid.
Hence, in this case scenario; it follows that;
48 = 1/2(x + 3x) 648 = 12xx = 48/12a = x = 4cm
b = 3x = 12cm.

find the greatest common factor of 12w^4 and 5y^3
Answer:
1.
Step-by-step explanation:
The greatest common factor is the largest positive integer that divides evenly into all numbers with zero remainder.
So, let's factor each number:
12w⁴: To factor it, factor 12 and w⁴ separately.
12: 1, 2, 3, 4, 12
w⁴: 1, w, w², w³, w⁴
So, the factor of 12w⁴ is all the combinations of the factor of 12 and w⁴.
1, 2, 3, 4, 12, 1w, 2w, 3w, 4w, 12w, 1w², 2w², ..., 12w⁴
5y³: To factor it, factor 5 and y³ separately.
5: 1, 5
y³: 1, y, y², y³
So, the factors of 5y³ are all the combinations of the factor of 5 and y³.
1, 5, 1y, 5y, 1y², ... , 5y³
The only factor that 12w⁴ and 5y³ have in common is 1.

Answer:
37.2 cm
Step-by-step explanation:
Perimeter of a rectangle = 2*(length + breadth)
length = 12 cmwidth = 6.6 cm==> perimeter = 2*(12 + 6.6)
= 2*(18.6)
= 37.2 cm
Answer:
[tex] \red{37.2 \: cm}[/tex]
Step-by-step explanation:
The formula to find the perimeter of a rectangle is:
[tex] \text{perimeter} = 2(l + w)[/tex]
Given that,
length = 12cm
width = 6.6cm
Let us find the perimeter of the rectangle now.
[tex] \text{perimeter} = 2(l + w) \\ \text{perimeter} = 2(12 + 6.6) \\ \text{perimeter} = 2 \times 18.6 \\ \text{perimeter} = 37.2 \: cm[/tex]

Step-by-step explanation:
equation of a circle: [tex](x - h)^2+(y-k)^2=r^2[/tex]
where (h, k) = center and r = radius
From inspection, we can see that the center of the circle = (0, 0)
and the radius = 1
[tex]\implies (x - 0)^2+(y-0)^2=1^2[/tex]
[tex]\implies x^2+y^2=1[/tex]
Substitute [tex]y=\frac{\sqrt{3}}{2}[/tex] into [tex]x^2+y^2=1[/tex] and solve for [tex]x[/tex]:
[tex]\implies x^2+(\frac{\sqrt{3}}{2})^2=1[/tex]
[tex]\implies x^2+\frac{3}{4}=1[/tex]
[tex]\implies x^2=\frac{1}{4}[/tex]
[tex]\implies x=\pm \sqrt{\frac{1}{4}}[/tex]
[tex]\implies x=\pm\frac{1}{2}[/tex]

room are seated in
seven-eighths of the chairs. The
rest of the people are standing.
If there are 8 empty chairs.
How many people are in the room
The number of people in the room is 91.
What is the total number of chairs in the room?The first step is to determine the total number of chairs in the room. In order to determine this value, divide the fraction of the unoccupied chairs by the number of empty chairs.
8 ÷ 1/8
8 x 8 = 64
What is the number of people in the room?Number of people sitting on the chairs = 64 - 8 = 52
Number of people in the room = 52 ÷ 4/7
= 52 x 7/4 = 91
