Answer:
= 20 square units
Step-by-step explanation:
First we calculate the obvious square without the extra points. The side length of the square is four; therefore, the area of the square is 16 square units. The points are each 1 square unit as they split the squares down the midde. In total, 16 + 4(1) = 20.

Diego and Jada are both trying to write an expression with fewer terms that is equivalent to
7a+5b−3a+4b
Jada thinks 10a+1b is equivalent to the original expression.
Diego thinks 4a+9b is equivalent to the original expression.
Substitute your own values for “a” and “b” and determine if the expressions are equivalent. Show your work in the space provided.
Answer:
Diego's answer 4b+9b is correct:)
Step-by-step explanation:
Our first step is to combine like terms.
Causing you to combine 7a and -3a which gives you 4a because 7-3=4
Next, you would combine 5b and 4b which gives you 9b because 5+4=9
After you have combined like terms you would have your simplified equation 4b+9b causing Diego's answer to be correct!
Hope this helps!
Please tell me if I am wrong, I enjoy learning from my mistakaes:)
Have a great rest of your day:)

Last week at the park Haeather ran 4 miles in 48 minutes when she runs her next race she Hope's to improve her time by 2 minutes per mile
Last week at the park what was haeather rate of speed in miles per hour
Answer:
Haeather ran at a speed of 5 miles per hour.
Step-by-step explanation:
Given that last week at the park Haeather ran 4 miles in 48 minutes, to determine what was Haeather rate of speed in miles per hour the following mathematical calculation must be performed:
48/4 = 12
Thus, Haeather ran 1 mile every 12 minutes.
60/12 = 5
1 x 5 = 5
Therefore, Haeather ran at a speed of 5 miles per hour.

1. Find the equation of the line that passes through the point
(2,12) and is parallel to the equation below.
y = 40 - 1
A. y = 43 – 20
B.y = 45 + 4
C. y = + 14
D.y = x + 10
Answer:
None of the above ? （the equation should be y=12）
Step-by-step explanation:
the line parallel to line y=40-1=39 means it's a horizontal line. Which means it's y coordinate is also a constant. Since it pass through （2,12）,it means the constant of y is 12.

What is the total interior measure of the polygon?
And what’s the value of x?
Answer:
x =196°
Step-by-step explanation:
The polygon is 5 sided, therefore, total interior angles of a pentagon is:
(n - 2) 180
(5 - 2) 180
(3) 180
540°
96° + 112° + 102° + 84° + x° = 540°
394° + x = 540°
Collect like terms
x = 540° - 394°
x = 196°
#2.) Shipment Times. A survey of 36 selected recording companies showed these numbers of days that it took to receive a shipment from the day it was ordered. Find the class mean and the modal class for the data.
Days / Frequency
1-3 6
4 - 6 8
7-9 10
10 - 12 7
13 - 15 0
16 - 18 5
Answer:
1. Mean => 8.2
2. Modal class => 7 - 9
Step-by-step explanation:
From the question given above, the following data were obtained:
Days >>>>>> Frequency
1 - 3 >>>>>>> 6
4 - 6 >>>>>> 8
7 - 9 >>>>>> 10
10 - 12 >>>>> 7
13 - 15 >>>>> 0
16 - 18 >>>>> 5
Next, we shall determine the the day mark.
The day mark is obtained by adding the the lower and upper class intervals and diving the result by 2.
This is illustrated below:
Days >> Day mark >>> Frequency
1 - 3 >>> 2 >>>>>>>>>> 6
4 - 6 >>> 5 >>>>>>>>> 8
7 - 9 >>> 8 >>>>>>>>> 10
10 - 12 >> 11 >>>>>>>> 7
13 - 15 >> 14 >>>>>>>> 0
16 - 18 >> 17 >>>>>>>> 5
1. Determination of the mean.
Summation of (day mark × frequency) = (2×6) + (5×8) + (8×10) + (11×7) + (14×0) +(17×5)
= 12 + 40 + 80 + 77 + 0 + 85
= 294
Summation of frequency = 6 + 8 + 10 + 7 + 0 + 5
= 36
Mean = Summation of (day mark × frequency) / Summation of frequency
Mean = 294 / 36
Mean = 8.2
2. Determination of the modal class.
The modal class is simply the class with the highest frequency.
Days >>>>>> Frequency
1 - 3 >>>>>>> 6
4 - 6 >>>>>> 8
7 - 9 >>>>>> 10
10 - 12 >>>>> 7
13 - 15 >>>>> 0
Considering the data given above, the class with the highest frequency is 7 - 9.
Thus, the modal class is => 7 - 9

find 3 numbers in GP whose sum is 28 and product is 512
Answer:
4,8 and 16Let the three numbers be a,ar, ar^2 ,
where r is the common ratio.
⇒a+ar+ar^2 =28 and a^3 r^3 =512
⇒ar=8⇒a+ar^2 =20
⇒8r^2 −20r+8=0
⇒r=2,r= 1/2
If r=2,a=4
Therefore, the three numbers are 4,8,16.

Is 3.13 greater than 3.12
Answer:
yes
Step-by-step explanation:
if we figure out the difference between the two numbers by subtracting one from the other, if the product comes out positive, then the number you subtracted from is greater, if the product comes up negative, then the number you subtracted from is lesser
say we did 3.13 as our first number
3.13 - 3.12 = 0.01
this means that 3.13 is greater by 0.01, if we switch the two numbers however...
3.12 - 3.13 = -0.01
then that means that 3.12 is lesser by 0.01
i hope this makes sence, working with decimals may get tricky sometimes lol
Yes, 3.13 is greater than 3.12.
What is decimal?A decimal number is a number in which whole number part is separated from a decimal.
How to find greater number?We have been given two numbers 3.13 and 3.12 and we have to find the greater number from these two numbers. When two numbers are in decimal then firstly we have to see the digit before the decimal, the number having large digit becomes large. If the digit before decimal is same in both numbers then we have to see whether the first digit after the decimal is greater or not. If this digit is also same then we will move towards left and so on.
In the numbers 3.12 and 3.13, 3 which is second digit after decimal is greater than 2. So 3.13 is greater than 3.12.
Hence 3.13 is greater than 3.12.
