How far did the car travelled?
151.5 miles
Step-by-step explanation:
50.5 × 3 = 151.5
Answer:
151.5 Miles
Step-by-step explanation:
A constant speed means the speed was the same throughout the whole trip, also meaning there were no stops. So the answer is as simple as 50.5x3

A function graph of a line with two points (-3,-2) and (-1,2) with an x axis of negative five to five and a y axis of negative five to five
9514 1404 393
Answer:
y = 2x + 4
Step-by-step explanation:
You have the graph, so you can read the slope and y-intercept from it. The line goes up 2 units for each unit to the right, so the slope is ...
slope = rise/run = 2/1 = 2
The y-intercept is where the graph crosses the y-axis, at y=4.
The slope-intercept form of the equation for a line is ...
y = mx + b
where m is the slope (2) and b is the y-intercept (4). Your equation is ...
y = 2x +4

Jeff ordered 5 pizzas for his daughters birthday
party. Each pizza has 8 slices. At the party, 50%
of the pizzas were eaten. When the party was
over, Jeff ate 20% of what was left. How many
did Jeff eat?
Answer:
4 slices.
Step-by-step explanation:
5 x 8 = 40. 40 slices of pizza divded by 2 since 50% = 2.
20 slices, 20% of 20 slices or 20 in general is 4
How many factors of 100 are also multiples of 5?
Let us write the factors of 100. A factor of 100 can only be a multiple of five if it is divisible by five.
Divisibility rule of 5: A number can only be divisible by five if the ones digit of the number is a five or 0.Factors of 100 ⇒ numbers divisible by 100 ⇒ 1, 2, 4, 5, 10, 20, 25, 50, 100
When checking each factor of 100;
1 is not a multiple of 5 ⇔ not divisible by 5.2 is not a multiple of 5 ⇔ not divisible by 5.4 is not a multiple of 5 ⇔ not divisible by 5.5 is a multiple of 5 ⇔ divisible by 5.10 is a multiple of 5 ⇔ divisible by 5.20 is a multiple of 5 ⇔ divisible by 5.50 is a multiple of 5 ⇔ divisible by 5.100 is a multiple of 5 ⇔ divisible by 5.⇒ Five factors are multiples of 5.
Therefore, five factors of 100 are multiples of 5.
carla, bev, and ashley took their unit 2 math test. carla made an 80 and bev made a 75. what was ashleys score on the test if their average was 78.

Determine the range of the following graph:
Answer:
The range of the graph is [tex]Ran\{f\} = [-4, 11)[/tex].
Step-by-step explanation:
From Function Theory we identify the range of the function as the set of values on vertical axis (y-axis). According to the graphic, we find that the range of the following graph, which represents a bounded function, is:
[tex]Ran\{f\} = [-4, 11)[/tex]
The range of the graph is [tex]Ran\{f\} = [-4, 11)[/tex].
A mountain road rises 10 feet over a 206-foot run. What is its slope?
It's slope is 5/103 , by using simple calculation for slope.
What is slope?
In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction. The letter m is frequently used to represent slope; the reason for this usage is unclear, but it can be found in O'Brien's (1844) and Todhunter's (1888) formulations of the equation for a straight line as "y = mx + b" and "y = mx + c," respectively. The ratio of the "vertical change" to the "horizontal change" among (any) two distinct points along a line is used to calculate slope. The ratio can also be written as a quotient (also known as "rise over run"), which gives the same number for each and every two distinct points on same line.
Mathematically, it's calculated as "rise over run".
Here,
Rise is given i.e. 10feet.
and foot-run=206.
So, slope = Rise/foot-run
= 10/206
= 5/103 .
Hence, slope = 5/103.

Answer:
2.) undefined slope 3.) zero slope (i'm not sure what 1 and 4 are, sorry!)
Step-by-step explanation:
undefined slope has the same x-coordinate and the denominator becomes 0. it also is a vertical line. for a zero slope, it has the same y-coordinate and the numerator is 0. this is a horizontal line. *this is my first response so if i am wrong, that is embarrassing*

please show work
Answer:
Step-by-step explanation:
5x+9y=-3 Multiply both sides by 8
40x+72y=-24
-53x-8y=-3 Multiply both sides by 9
-477x -72y= -27
sum the equations vertically to eliminate one variable
40x+72y= -24
-477x-72y= -27 (the y cancels out )
-477x =-51 (-24 + -27=-51)
-477x=-51 / -477 divide both sides by -477
x =51/437
5x 51/437=9y= -3 substitute the value of x
y= -174 /437
(x,y) = (51/437, -174/437)

A number t multiplied by −4 is at least −25.
Answer:
[tex]t\leq 6.25[/tex] in decimal form
[tex]t\leq \frac{25}{4}[/tex] in fractional form
Step-by-step explanation:
-4 times a number t is greater than or equal to - 25. This is what they mean by at least.
[tex]-4t \geq -25[/tex]
Solve for t.
[tex]t\leq \frac{-25}{-4}[/tex] , we flip the inequality because we are dividing by a negative number.
[tex]t\leq 6.25[/tex]
Write the equation of the line that passes through the points (-8,-5) (5,−8)
Answer:
y=-3/13x-89/13
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-8)-(-5)/5-(-8)
m=-3/13
y-y=m(x-x1)
y-(-8)=-3/13(x-5)
y+8= -3/13x+15/13
-8 -8
y=-3/13x-89/13
The total area of the polygon is 176 square feet. Find the value of x. x= ft
Answer:
x = 6 ft
Step-by-step explanation:
Area of the polygon = area of the square + 2(area of the triangle)
Area of the polygon = 176 ft²
Area of the square = length × width = 16 × 8 = 128
Area of the two triangles = 2(½*base*height) 2(½*x*8) = 8x
Plug in the above values into the equation for area of the polygon. Thus:
176 = 128 + 8x
Subtract 128 from each side
176 - 128 = 8x
48 = 8x
Divide both sides by 8
6 = x
x = 6 ft
Answer:
x=6ft
