Answer:
Triangle A: 38 degrees
Triangle B: Unknown (not enough information)
Triangle C: Unknown (not enough information)
Triangle D: 70 degrees
Triangle E: 40 degrees
Step-by-step explanation:
Work for Triangle A: 90 + 52 = 142. 180 - 142 = 38.
Work for Triangle B: Unidentifiable because there is no indicator to tell you if any of the angles/lines are equal. Generally there will be a "double lined" indicator in the corners of which a triangles angles are equal.
Work for Triangle C: Same as B.
Work for Triangle D: 90 + 20 = 110. 180 - 110 = 70.
Work for Triangle E: 90 + 50 = 140. 180 - 140 = 40.

Answers
Answer:
3/4
Step-by-step explanation:
From the plotted number line :
The Outlier value can be determined :
Q1 = 0.25(n+1)th term
Q1 = 0.25(21)th term = 5.25th = (2 1/4 + 2)/2 = 2.125
Q3 = 0.75(21)th term = 15.75th = 2 1/2
IQR = Q3 - Q1 = 2.5 - 2.125 = 0.375 = 3/8
Q1 - 1.5(IQR) = 2.125 - (1.5*0.375) = 1.5625
Q3 - 1.5(IQR) = 2.5 + (1.5*0.375) = 3.0625
Hence, Outlier values will be :
Values < 1.5625 and
Values > 3.0625
The Outlier value in the data is 3/4

Georgie put $500 in her savings account, earning interest at a rate of 4% each year. She did not make any more deposits or withdrawals. a) How much money was in the account after one year? b) How much money was in the account after 4 years? c) Was the amount of money earned in interest the same or different each year?
Answers
Answer:
a) $520
b) $580
c) Interest amount is same each year
Step-by-step explanation:
Given - Georgie put $500 in her savings account, earning interest at a rate of 4% each year. She did not make any more deposits or withdrawals.
To find - a) How much money was in the account after one year?
b) How much money was in the account after 4 years?
c) Was the amount of money earned in interest the same or different each year?
Proof -
Here given that,
Principal amount = $500
rate of interest = 4% = 4/100 = 0.04
Now,
a)
Amount = P [ 1 + RT ]
= 500 [ 1 + 0.04(1)]
= 500 [ 1 + 0.04] = 520
⇒Amount = $520
b)
Amount = P [ 1 + RT ]
= 500 [ 1 + 0.04(4)]
= 500 [ 1 + 0.16] = 580
⇒Amount = $580
c)
In 2nd year,
Amount = P [ 1 + RT ]
= 500 [ 1 + 0.04(2)]
= 500 [ 1 + 0.08] = 540
⇒Amount = $540
Now,
Interest in 1st year = 520 - 500 = 20
Interest in 2nd year = 540 - 520 = 20
So,
The interest amount is same each year

Answer:
TO FIND THE AREA OF A RECTANGLE, THAT IS L×B OR L× W (WIDTH/BREADTH) IS THE SAME THING. KEEP THAT IN MIND. SO : 90FT × 150FT. = 13500FTSQ. BUT WE ARENT FINISHED . YOU NEED TO FIND THE AREA OF BOTH SEMICIRCLES (SEMI MEANS HALF) , SO HENCE, THE AREA OF BOTH HALF SEMICIRCLES. THAT IS : PIRSQUARED. PI×R×R. THE RADIUS IS UNKNOWN. SO WE WILL USE THE DIAMETER TO FIND THE RADIUS SINCE THE DIAMETER IS TWICE THE RADIUS. THAT IS : 90÷2 , THAT IS = 45.SO WE KNOW THE RADIUS OF EACH SEMI CIRCLE IS 45. SO NOW :
PIRSQUARED = PI × R×R 3.14 × 45×45 OR 45SQUARED.THAT IS : 6,358.5 FT SQUARED. NOW 6,358.5FT SQ IS ONLY THE AREA OF ONE SEMICIRCLE. SO NOW WE KNOW THAT BOTH SEMICIRCLES HAVE A AREA OF 6,358.5 FT SQ.WE WILL ADD : 6,358.5 + 6,358.5 = 12,717.YOU ARE GOING TO ADD THE AREA OF BOTH HALF CIRCLES TO THE AREA OF THE RECTANGLE.
= 26,217FT SQ.
SINCE THEY ARE PROBABLY ONLY ASKING FOR THE AREA OF THE RECTANGLE, THEN THE ANSWER WOULD BE 13500FT SQ INSTEAD OF 26,217. NOT SUREAnswer:
C, 19858.5 [tex]ft^2[/tex]
Step-by-step explanation:
Imagine that these are two semi-circles on either side of a rectangle
the diameter of the semi circle is 90, and the radius is half of the diameter.
this means the radius is 45 (for both circles)
so now lets apply that to the area of a full circle, [tex]\pi r^2[/tex]
replace r with the radius [tex]\pi 45^2[/tex]
using 3.14 as pi, your answer should be 6358.5
but now remember that his is the area of a full circle, not a semi circle, so we must divide by 2 to get the semi circle area, which would then be 3179.25
since there's two semi circles, you would multiply this by two and now you're back to 6358.5
if that was confusing you can think of it as a full circle split into two parts on either side of the rectangle rather than two semicircles, so the two split pieces would add together to make the area of a full circle
now calculate the area of the rectangle, which is length times width
150 * 90 = 13500
so add the area of the rectangle to the area of the two semicircles and the answer is 19,858.5 :)
2. The store bought a pair of shoes for $60, and sold
it for $100. What percentage was the markup?
Answers
Answer:
33.3%
Step-by-step explanation:
Given data
Cost of shoes= $60
Selling price = $100
% markup = (selling-cost/cost)*100
% markup = (100-75/75)*100
% markup = (25/75)*100
% markup = (0.33333333333)*100
% markup =33.3%
Hence the markup is 33.3%

If x=7 then which answers would I circle? A. X + 7 = 17 b. 7 = 17 - x c. 70 = 10x d. X/35 = 5 e. 15x = 105
Answers
Answer:
C. 70 = 10x
E. 15x = 105
Step-by-step explanation:
x = 7
Using method of elimination;
A. X + 7 = 17
Substituting the value of x;
7 + 7 ≠ 17 (Incorrect option)
B. 7 = 17 - x
Substituting the value of x;
7 ≠ 17 - 7 (Incorrect option)
C. 70 = 10x
Substituting the value of x;
70 = 10 * 7 (Correct option)
D. X/35 = 5
Substituting the value of x;
7 / 35 ≠ 5 (Incorrect option)
E. 15x = 105
Substituting the value of x;
15 * 7 = 105 (Correct option)

We must be happy enough to find the value of only one valuable here, that is, x.
therefore, x-1/3=3
To find what is x-1, all we need to do is,
Take the denominator of the fraction to the answer (3)and multiply them. (that's how you'll find the values in the numerator)
So, you'll get,
x-1=3*3
x-1=9
To find the value of x,
The other number (-1) should be taken to the answer (9)
(Remember that the sign changes when the number crosses the equals sign)
therefore,
x= 9 + 1 (-1 will turn to +1 on crossing the equal sign)
Therefore , by addition, normally,
you'll get x=10

In your task this would be:

Now you have to calculate the area of the triangle. The formula for this is: Height x Length of the base x 1/2
So in your task this would be:
7ft x 5ft x 1/2 = 17.5 square ft
(you get the 7ft by subtracting 6ft from 13ft, which results in the height of the triangle)
Now you just add those two surfaces areas together:
52 square ft + 17.5 square ft = 69.5 square ft

Answers
Answer:

Explanation:
the formula for calculating the average grade would be the total score of all students ÷ the number of students. in this case, that would be:
(100 + 50 + 50 + 50 + 50) ÷ 5
= 300 ÷ 5
= 60
so, the average grade is 60.
