The equation for the circle below is x2 + y2 = 16. What is the length of the
circle's radius?
Answers
Answer:
4
Step-by-step explanation:
The general equation circle is
[tex] {x}^{2} + {y}^{2} = {r}^{2} [/tex]
Where r is the radius
Plug in the equation
[tex] {x}^{2} + {y}^{2} = 16[/tex]
Take the sqr root of 16 tocfind the radius
[tex] \sqrt{16} = 4[/tex]

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.
Answers
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!

Is 3.13 greater than 3.12
Answers
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.

The length of a rectangle is 13 centimeters less than its width. What are the dimensions of the rectangle if its area is 140 square centimeters?
Answers
Answer:
Dimensions = 7 cm by 20 cm.
Step-by-step explanation:
Let the length and width of the rectangle be L & W respectively.
Given the following data;
Area of rectangle = 140 cm²
L = W - 13
To find the dimensions of the rectangle;
The area of rectangle = L * W
Substituting into the above formula, we have;
140 = L * W
140 = (W - 13) * W
140 = W² - 13W
W² - 13W - 140 = 0
Solving the quadratic equation using factorization method;
Factors are -20 and 7
W² - 20W + 7W - 140 = 0
W(W - 20) + 7(W - 20) = 0
(W - 20)(W + 7) = 0
W - 20 = 0
W = 20
W + 7 = 0
W = -7
Thus, W = 20 or -7
But the width has to be positive, W = 20 centimeters.
Next, to find the length of rectangle
L = W - 13
L = 20 - 13
L = 7 centimeters.

#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
Answers
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

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
Answers
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.
