Answer: 39.25
========================================
Work Shown:
d = diameter = 10
r = radius = d/2 = 10/2 = 5
A = area of a full circle
A = pi*r^2 = 3.14*5^2 = 78.5
Cut this in half to get the area of a semicircle (aka half circle)
(78.5)/2 = 39.25
This result is approximate.

H
a
104°
K
76
measure of angle H =
measure of angle K = 137
Answer:
∠H = 137°
∠K = 76°
Step-by-step explanation:
The sum of the interior angles of a trapezoid = 360°
In a trapezoid, the angles on the same leg (called adjacent angles) are supplementary, meaning they add up to 180°
The legs are the non-parallel sides: JK and HI
Therefore, 104 + ∠K = 180
⇒ ∠K = 180 - 104 = 76°
And, ∠H + 43 = 180
⇒ ∠H = 180 - 43 = 137°
Sum of two adjacent angles in trapezium equals 180°
[tex]\\ \tt\hookrightarrow <H+43=180[/tex]
[tex]\\ \tt\hookrightarrow <H=180-43[/tex]
[tex]\\ \tt\hookrightarrow <H=137[/tex]
And
[tex]\\ \tt\hookrightarrow <K+104=180[/tex]
[tex]\\ \tt\hookrightarrow <K=180-104[/tex]
[tex]\\ \tt\hookrightarrow <K=76°[/tex]

While shopping at the mall, Tom bought 3 hats and 4 pairs of glasses and spent $123. His friend Jerry bought the same type of items consisting of 1 hat and 3 pairs of glasses and spent $66. How much does a pair of glasses cost? How much does a hat cost?
Answer:
a pair of glasses costs $17
a hat costs $21
Step-by-step explanation:
h = hat
g = glasses
3h + 4g = 123
1h + 3g = 66
multiply the 2nd equation by 3
3h + 9g = 198
negate everything in the 1st equation and add it to the 'new' 2nd equation
3h + 9g = 198
+ -3h - 4g = -123
5g = 75
g = 15
substitute the 15 in either one of the 1st equations
1h + 3(15) = 66
h + 45 = 66
h = 66-45
h = 21
to check, substitute both g=15 and h=21 into BOTH 2 original equations.
What number is in between 6534 and 6565
Answer:
I am assuming any number in between these two, so let's just say 6,550.
Step-by-step explanation:
If you count up from 6,534, you will eventually get to 6,550. If you continue to count up, you will eventually reach 6,565 which is bigger than 6,550.

If each of the numbers in the following data set were multiplied by 18, what
would be the new median of the data set?
14, 20, 18, 58, 71, 36, 28
what would be the new median of the data set ?
The answer is 28 or 504. My explanation....
ALRIGHT! So, it took me a little while to do it all.... since I wasn't really sure if it was already multiplied by 18 or not.
So the normal numbers in order from least to greatest,(because that's easier)
14, 18, 20, 28, 36, 58, 71.
The new numbers I multiplied by 18 are...
252, 324, 360, 504, 648, 1044, 1268.
When I put it like that you can clearly see the new median. 28 and 504!

tell whether the sequence is arithmetic if it is what is the common difference?
19, 12, 5, -2
no
yes; 1/7
yes;7
yes;-7
Answer:
(d) yes; -7
Step-by-step explanation:
The differences between terms are ...
12 -19 = -7
5 -12 = -7
-2 -5 = -7
These are all the same, so this difference is "common". A sequence in which terms have a common difference is an arithmetic sequence.
This sequence is arithmetic, with a common difference of -7.

If you only have a 1 3 cup measuring cup and a recipe calls for 5 1 3 cups of flour, how many 1/3 cups would you need to use?
Answer:
You would need 16 1/3 cups!
Step-by-step explanation:
I used an equation, but you could also use mental conversions! :
1/3c = 5 1/3
(1/3c)3 = (5 1/3)3 (multiply each side by 3 (3/1))
3c /3 = (48) /3 (divide each side by 3)
c = 16
:)
(c = cups!)
The requried number of 1/3 cups to make the recipe is 16.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
here,
Measuring cup = 1/3
Recipe required number of cups = 5 1/3 of flour,
Let the number of 1/3 cups = x
1/3x = 5 1 / 3
x/3 = 16 / 3
x = 16
Thus, the requried number of 1/3 cups to make the recipe is 16.

HELP ME FIND MIDPOINT
Answer: (-1/2, 0) which is the same as saying (-0.5, 0)
================================================
Explanation:
The x coordinates of A and B are -2 and 1 respectively.
Add up those values to get -2+1 = -1
Then cut that result in half: -1/2 = -0.5
This is the x coordinate of the midpoint.
--------
Repeat for the y coordinates:
Add: 1 + (-1) = 0
Cut in half: 0/2 = 0
The y coordinate of the midpoint is 0
-------
Overall, the midpoint is located at (-1/2, 0) which is the same as writing (-0.5, 0). This is where the segment AB crosses the x axis.
