Hi!
The area of the entire figure is 76 units squared.
NOTE: This question has two different shapes: a rectangle, and a triangle.
Rectangle Formula:
Length * Width = Area
[tex]LW=A[/tex]
Triangle Formula
(Base * Height) / 2 = Area
[tex]\cfrac{bh}{2}=A[/tex]
Let's first get the rectangle's area:
[tex]LW=A[/tex]
[tex]8*7=A[/tex]
[tex]56=A[/tex]
The area of the rectangle is 56.
Now, for the top triangle:
[tex]\cfrac{bh}{2} =A[/tex]
[tex]\cfrac{8*2}{2} =A[/tex]
[tex]8=A[/tex]
The area of the top triangle is 8.
Now, for the bottom triangle.
[tex]\cfrac{bh}{2} =A[/tex]
[tex]\cfrac{8*3}{2} =A[/tex]
[tex]12=A[/tex]
The area of the bottom triangle is 12.
Now, add them all together:
[tex]56+8+12=76[/tex]
A train travels from Washington D.C. to New York (225 miles). The train departs at 4:55 PM and arrives in New York at 7:55 PM. What is the average speed of the train?
7:55 pm - 4:55 pm = 3 hours
225 miles / 3 hours = 75 miles per hour
Average speed = 75 miles per hour
What is the area for 12ft and 8.5 for a parallelogram
Answer:
102 ft^2
Step-by-step explanation:
Im pretty sure area for a parallelogram is the same as a rectangle, so A = bh which would be 12 x 8.5
simplify the answer should be 2/5 i just don’t understand how to get it
Step-by-step explanation:
((8x⁶)²)⅙ = (64x¹²)⅙
= (2⁶x¹²)⅙
= 2x²
(625x⁸)¼ = (5⁴x⁸)¼
= 5x²
2x²/5x² = 2/5

Dale wants to order business cards for his new job.
• Company A charges a flat fee of $0.15 per card.
• Company B charges $0.10 per card plus an additional $10.00 for delivery
Write an inequality for the amount of business cards, c, that Dale would need to buy for Company to be cheaper
Dale would need to buy more than 200 cards for Company B to be cheaper.
What is inequality?Inequality is defined as the relation which makes a non-equal comparison between two given functions.
Company A charges a flat fee of $0.15 per card.
Company B charges $0.10 per card plus an additional $10.00 for delivery
Let x = number of cards
Company A charges = $0.15x
Company B charges = $10.00 + $0.10x
For company B to be the cheaper option ( B < A )
$10.00 + $0.10x < $0.15x
$10.00 < $0.05x
subtracting positive from both sides to retains the sense of the inequality and x is positive
200 < x
x > 200
So, Dale would need to buy more than 200 cards for Company B to be cheaper.

Kate packs snow into 5 identical jars. each jar represents a different depth of snow. kate then lets the snow in each jar completely melt. the table shows the height of the liquid in each jar as it relates to the original depth of snow in the jar. a 2-column table with 5 rows. the first column is labeled snow depth (inches), x with entries 2, 4, 6, 8, 10. the second column is labeled water depth (inches), f(x) with entries 0.4, 0.8, 1.2, 1.6, 2.0. which statements are true about the relationship between the depth of the snow and the height of water in the jar after the snow is melted? select two options. the points on a graph representing the relationship lie on a line. there is 0.4 inch of water to every 1 inch of snow. a line through the points will pass through (0, 0). the function relating snow depth to water depth is quadratic. the data can be represented by f(x) = 0.2x.
The true statements include the point on the graph represents the relationship lie on a line and a line through the points will pass through (0, 0).
How to illustrate the table?From the table, the water depth changes for about (0.8 - 0.4) = 0.4 inches. Here, the function is a linear model.
In this case, the the point on the graph represents the relationship lie on a line and a line through the points will pass through (0, 0).

What is the equation that represents the function
Answer:
y= 1/5 x -1
Step-by-step explanation:
Find two points ( any two of the three given)
find the slope between 5,0 and 10, 1
( 1-0)/(10-5) = m = slope = 1/5
so the line is of the form y = mx + b :
y = 1/5 x + b sub in any point to calculate 'b'
1 = 1/5 (10) + b
b = -1
y = 1/5 x -1 is your answer
The number of items, n, made in 1 hour by a machine is given by n=30/t, t is the time in minutes the machine takes to make one item. The value of r changes for different types of item. On the grid, plot the points that would be used to draw the graph of n = 30/t for values of t from 1 to 4
The equation n = 30/t is an illustration of an inverse variation
The points on the graph are: (1,30), (2,15), (3,10) and (4,7.5)
How to plot the graph?The equation is given as:
n = 30/t
When t = 1, we have:
n = 30/1
n = 30
When t = 2, we have:
n = 30/2
n = 15
When t = 3, we have:
n = 30/3
n = 10
When t = 4, we have:
n = 30/4
n = 7.5
So the points on the graph are:
(1,30), (2,15), (3,10) and (4,7.5)

A composite figure is formed by combining a square and a triangle. Its total area is 49.5 ft. The area of the
triangle is 33.5 ft. What is the length of each side of the square? Complete the explanation.
The area of the square is
it?, so each side of the square is
ft.
Answer:
The length of each side of square is 5ft.
Step-by-step explanation:
A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft squared.
The area of the triangle is 7.5ft squared.Area of combined figure - area of triangle = area of square.
32.5 ft squared - 7.5 ft squared = 25 ft squared.
So, area of square = 25 ft squared.
Now, by putting the formula for getting the length of each side:
Let the side = a.
Area of square = 25 ft squared
Area of square = a²
Using square root both sides we get:
So, the side = 5 ft.
Therefore, the length of each side of square is 5ft.

Martina's inground swimming pool is finally finished, and all that's left to do is fill it with water. Martina's family decides to fill their pool using their garden hose to save money, even though they know it will take a really long time. The swimming pool is 10 meters long and 5 meters wide, and Martina's family wants the water to be 2 meters deep. Water from the garden hose flows at a rate of 2,500 liters, or 2.5 cubic meters, per hour.
How long will it take to fill the pool?

Find the required water volume using the volume of prism formula
V = lwhV = 10*5*2 = 100 m³Find the time required
100/2.5 = 40 hoursAnswer:
40 hours
Step-by-step explanation:
The swimming pool can be modeled as a rectangular prism.
Volume of a rectangular prism
[tex]V = lwh[/tex]
where:
l = lengthw = widthh = heightFirst, calculate the volume of water needed:
Given:
l = 10 mw = 5 mh = 2 mSubstitute the given values into the formula and solve for V:
[tex]\implies V=10 \cdot 5 \cdot 2=100\:\: \sf m^3[/tex]
If the water flows as a rate of 2.5 m³/h, divide the volume by the rate to calculate how long it will take to fill the pool:
[tex]\implies \sf Time=\dfrac{Volume}{rate}[/tex]
[tex]\implies \sf Time=\dfrac{100}{2.5}[/tex]
[tex]\implies \sf Time=40\:\:hours[/tex]
what are the mean,median,mode, and range of the data set given the altitude of lakes in feet:-11,-28,-17,-25,-28,-39,-6,and -46? i dont know the answer
Answer:
Read explanation.
Step-by-step explanation:
The average is -22.2 (mean)
-46,-39,-28,-28,-25,-17,-11.-6 You cross out the lowest and highest until you reach the middle, which is -26.5(median)
The mode is -28 as it is the most repeated number
The range is 40 as when you subtract a negative it turns into the absolute value.
