Answer:
10 ft by 12 ft
Step-by-step explanation:
This problem requires you to first write an equation to represent the situation. Here we will represent the shorter side of the doghouse with the variable x, the longer side will be represented with x+2 because it is 2 feet longer.
48 = x * (x+2)
This represents the area of the doghouse as the product of the width and length of the doghouse.
48 = x^2 + 2x
Now, we need to move all the items onto one side of the equals sign, it is best to have the x^2 be positive.
0 = x^2 + 2x - 48
Now, we factor to find what x equals.
0 = (x-6) * (x+8)
From here, we can use each of the terms in parentheses to solve for x.
0 = x-6
x = 6
0 = x+8
0 = -8
Here we know that the shorter side has to be 6 ft because length is a positive number, and we can determine that the longer side is 8 ft because it is 2 ft longer. The dimensions of the slab are therefore 10 ft by 12 ft because the slab is 2 ft on each side, therefore adding an extra 4ft to the dimensions because the 2ft is added on each side.
Write an equation for the line in slope-intercept
form.
(Use integers or fractions for any numbers in the
equation.)
Answer:
y = 3x + 5
Step-by-step explanation:
Find the slope using two points on the line, say, (0, 5) and (-3, -4):
Slope (m) = ∆y / ∆x = (-4 - 5) / (-3 - 0) = -9/-3
m = 3
Find y-intercept (b):
y-intercept (b) is the value of y when x = 0. At this point, the line intercepts the y-axis.
When x = 0, y = 5
y-intercept (b) = 5
Write the equation by substituting m = 3 and b = 5 into y = mx + b
Thus:
y = 3x + 5

Answer: 2.8
Step-by-step explanation:
The Quadrilateral ABCD is just being rotated and nothing else, so the length of the segments don't change.
so whatever value for CD is also the the value for C'D' which is 2.8

Compare mean, median, mode, and standard deviation.
Answer:
The mean, median and mode are all estimates of where the "middle" of a set of data is. These values are useful when creating groups or bins to organize larger sets of data. The standard deviation is the average distance between the actual data and the mean.

Last night, 5 friends went out to dinner at a restaurant. They split the bill evenly. Each friend paid $11.50. If B represents the total bill in dollars, what equation could you use to find the value of B?
Answer:
B=11.5x5
Step-by-step explanation:
5 people pay $11.50 to get a total of B.
To get the total bill, 11.5x5=57.5
B=57.5
The total cost of the bill is $57.50.

Answer:
$38.16
Step-by-step explanation:
8% of $48 is $3.84 so we subtract $48-$3.84=$44.16. Because of the coupon we then remove $6. $44.16-$6=$38.16
Answer:
$38.16
Step-by-step explanation:
A quadrilateral has two angles that measure 70 and 60. The other two angles are in a ratio of 4:19 what are the measures of those two angles.
Answer:
We can obtain the answer from the Angle sum property of a quadrilateral.
Angle sum property of a quadrilateral =360 degrees.
So, 70+60+4x+19x=360 degrees
130+23x=360degrees
23x=360-130,230
23x= 230 divided by 23, 10
X=10
Angles are:-
4x=4*10=40
19x=19*10=190

How can data be represented in a scatter plot?
How can I use scatter plots to analyze two sets of data?
How can I determine the line of best fit, and how will this help me to make predictions?
How can I assess the accuracy of my line of best fit?
Answer:
1. Scatter plots are used to observe relationships between variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point.
2. A Scatter Analysis is used when you need to compare two data sets against each other to see if there is a relationship. Scatter plots are a way of visualizing the relationship; by plotting the data points you get a scattering of points on a graph
