Answer:
3 6/8
Step-by-step explanation:
30÷8=3 6/8
8×3=24
30-24=6
Answer:
The mixed that represents 30/8 is --> 3 3/4
Step-by-step explanation:
Step 1: Find the whole number
We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.
30/8= 3.75 = 3
Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.
Step 2: Get the new numerator
To work this out we'll use the whole number we calculated in step one (3) and multiply it by the original denominator (8). The result of that multiplication is then subtracted from the original numerator:
30 - (8 x 3) = 6
Step 3: Our mixed fraction
We've now simplified 30/8 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:
3 6/8
Step 4: Simplifying our fraction
In this case, our fraction (6/8) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 6 and 8 is 2.
We can now divide both the new numerator and the denominator by 2 to simplify this fraction down to its lowest terms.
6/2 = 3
8/2 = 4
When we put that together, we can see that our complete answer is:
3 3/4

What is the perimeter of this composite shape? ___ ft.
Use 3.14 for "pi" and round to the nearest hundredths place
Answer:
36.85 ft
Step-by-step explanation:
3 feet on either end + 6 feet on either side + circumference of the circle
3 + 3 + 6 + 6 + circumference of the circle
18 + circumference of the circle
You can find the circle's diameter by subtracting 6 from 12. You get 6. You can find the radius by dividing the diameter by 2. You get 3.
The formula for circumference is 2·π·Radius
2 · π · 3 = 6 · π = 6 · 3.14 ≈ 36.85

Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.
Evaluate the expression 2^x − x^2 for x=5.
Answer:
To evaluate the expression 2^x − x^2 for x=5, we need to substitute 5 for x and simplify. Using the order of operations, we get:
2^x − x^2
= 2^5 − 5^2
= 32 − 25
= 7
So, the expression 2^x − x^2 evaluates to 7 when x=5.

What is the distance traveled by the tip of the second hand of a clock in 1 minute if the hand is 10.5 inches long? Leave your answer in terms of π.
Answer:
(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.
Step-by-step explanation:
The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

Answer:
A
Step-by-step explanation
A is correct because the Median(also known as the second quartile) for the Chess club is 14 and that is greater then the Median of the Cheekers club which is 12 ( 14> 12 )
B is incorrect a lot to explain that is why there isn't a explanation
C is incorrect as well because the range for the chess club is 10 and the Range for the Checkers Club is 11. and so the Chess Club doesn't have more members than the Checker's Club dose.
D is incorrect because the 3rd Quartile for the Chess Clubs is 15 and the Checkers club is 15 too. So we know that they are equal to each other, not greater or less then.

Answer:
The answer is 288 inches!
Step-by-step explanation:
First you have to split the kite in multiple shapes. To be able to get the surface area of the top triangles, you have to do 32 - 20 to get the height, the answer would be 12. Then you can multiply the height times the width. (the width is 9) If you would do that you would get 108, but since it is a triangle you would need to divide that by 2. But, there is 2 triangles that have the same surface area so we will just keep it at 108. Now we have to get the surface area of the shapes at the bottom of the kite. It shows the width of both of the triangles but we will divide that by 2 to get the width of one, once doing that you will have a width of 6. You need to multiply the width times the height. (the height is 20) Doing that you will get 180, but since it is a triangle you need to divide that by 2. There is 2 triangles so we will just keep it at 180. So now we have to add the 2 groups of triangles together. The lower triangles have a surface area of 180 and the upper triangles have a surface area of 108. Adding those together will get our total surface area of 288 inches!

Answer:
D. None of the above.
Step-by-step explanation:
To evaluate the expression when x = 6, we substitute 6 for x in the expression:
2 - 3(x - 5)
= 2 - 3(6 - 5)
= 2 - 3(1)
= 2 - 3
= -1
Therefore, the value of the expression when x = 6 is -1.
So, the answer is D. None of the above.
Answer: none of the above
Step-by-step explanation:
When x = 6 We substitute 6 for x in the expression:
2 - 3(x - 5)
2 - 3(6 - 5)
2 - 3(1)
2 - 3
= -1
Marley surveyed the students in 7th grade to determine which type of social media they most commonly used. The data that Marley obtained is given in the table.
Type of Social Media Tweeter VidTok Headbook Picturegram
Number of Students 85 240 125 50
Which of the following circle graphs correctly represents the data in the table?
Choice A: a circle graph titled social media usage, with four sections labeled headbook 17 percent, picturegram 48 percent, tweeter 25 percent, and vidtok 10 percent
Choice B: a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Choice C: a circle graph titled social media usage, with four sections labeled tweeter 17 percent, vidtok 48 percent, headbook 25 percent, and picturegram 10 percent
Choice D: a circle graph titled social media usage, with four sections labeled picturegram 17 percent, tweeter 48 percent, vidtok 25 percent, and headbook 10 percent
Answer:
Choice C
Step-by-step explanation:
We first have to find the sum of the students.
85 + 240 + 125 + 50 = 500
Next, we have to find the percentage of each group of students for each group.
Users of Tweeter = 85 (17%)
Users of VidTok = 240 (48%)
Users of Headbook = 125 (25%)
Users of Picturegram = 50 (10%)
Therefore C is the answer

Triangle XYZ is similar to triangle JKL.
triangle XYZ with side XY labeled 8.7, side YZ labeled 7.8, and side ZX labeled 8.2 and triangle JKL with side JK labeled 10.44
Determine the length of side LJ.
8.79
9.36
9.84
10.13
Answer:
C) 9.84
Step-by-step explanation:
JK ~ XY
XY = 8.7
JK = 10.44
10.44/8.7 = 1.2
That’s the scale or dilation
LJ ~ ZX
ZX = 8.2
8.2 X 1.2 = 9.84
LJ = 9.84
The length of side LJ in the triangle JKL is 9.36.
We are given that triangle XYZ is similar to triangle JKL, which means that the corresponding sides are proportional.
We are also given the lengths of the sides of triangle XYZ, so we can use these lengths to find the corresponding sides of triangle JKL.
The ratio of the corresponding sides of triangle XYZ to triangle JKL is:
XY : JK = 8.7 : 10.44
YZ : KL = 7.8 : 9.36
ZX : LJ = 8.2 : x
Since the two triangles are similar, we know that the ratios of the corresponding sides are equal.
Therefore, we can set the two ratios equal to each other and solve for x, the length of side LJ:
8.7 / 10.44 = 7.8 / 9.36 = 8.2 / x
Cross-multiplying, we get:
8.7 * x = 10.44 * 7.8
x = (10.44 * 7.8) / 8.7
x = 9.36
Therefore, the length of side LJ is 9.36.

Pls answer this question ASAP i beg of u
Answer:
Step-by-step explanation:
To find the interquartile range, we first need to find the values of the first and third quartiles.
The median of the data set is 4. To find the first quartile, we take the median of the lower half of the data set:
1 1 3 3 | 4 4 5 7 7
^
First quartile = 3
To find the third quartile, we take the median of the upper half of the data set:
1 1 3 3 | 4 4 5 7 7
^
Third quartile = 7
The interquartile range is the difference between the third quartile and the first quartile:
7 - 3 = 4
Therefore, the interquartile range of the data set is 4.
In the data set below, what is the interquartile range?
23 58 58 64 76 87
Answer: IQR= 18
Step-by-step explanation:
First, you need to put the numbers in order from least to greatest, which they already are.
23, 58, 58, 64, 76,87
then, you draw an imaginary line down the middle of the numbers (between 58 and 64), and then you find the number in the middle of these. The Q1 is 58, and the Q3 is 76. In order to find the Interquartile range (IQR), you simply subtract the two.
76-58= 18
And you have your answer
Hope this helps!
Answer:
44
Step-by-step explanation:
First, we need to find the median in the data set.
It's between 58 and 64. To find the median, we add those two numbers and then divide by 2.
58 + 64 = 122
122 ÷ 2 = 61 (Mark this point in between the numbers on the data set)
median = 61
23, 58, 58, | 64, 76, 87
Now that we have the median, we have to find the upper quartile and the lower quartile in order to find the interquartile range.
Lets find upper quartile first. In order to do that, add up all the numbers to the right of the data set from the median point, then divide by 2.
64 + 76 + 87 = 227
227 ÷ 2 = 113.5
The same goes for the lower quartile (to the left).
23 + 58 + 58 = 139
139 ÷ 2 = 69.5
Lastly, to find the interquartile range, simply subtract the lower quartile from the upper quartile.
113.5 - 69.5 = 44
Therefore interquartile range = 44.
