Step-by-step explanation:
So we have to break the shapes down to triangle, rectangle and the small rectangle
Area of rectangle=WxL
Area of triangle= (BxH)÷2
triangle=
(23x11)÷2
=253÷2
=126.5m
rectangle=
9x19
=28m
square#2(the small one)=

=174.5m
Eric has 240 coins in his collection. 11\20 of his coins are pennies. 4\20 of the coins are nickels. The rest f the coins are quarters. How many of the coins are quarters? Explain how you got your answer.
Answers
Answer:Number of coins that are quarters =60
Step-by-step explanation:
Total coins in possession of Eric=240
Number of coins that are pennies=11\20 x 240= 132
Number of coins that are nickels=4\20 x 240= 48
Since the rest are quarters,
Number of coins that are quarters =Total coins in possession of Eric -( Number of coins that are pennies+ Number of coins that are nickels)
=240-(132+48)
=240-180
=60

For positive acute angles A and B, it is know that tan A= 8/15 and sin B= 11/61. Find the value of cos (a+b) in simplest form
Answers
Answer:
812/1037
Step-by-step explanation:
To solve this, we have to use trigonometric identities.
Cos (A + B) is given as Cos A Cos B - Sin A Sin B. And from the question, we have that
Tan A = 8/15.
We know that in a triangle, the Tan angle is represented Opp/Adj and thus the Opp is 8, and the Adj is 15. Using Pythagoras, we have
hyp² = opp² + adj²
hyp² = 8² + 15²
hyp² = 64 + 225
hyp² = 289
hyp = √289 = 17
The identity of Cos is Adj/Hyp and that of Sin is Opp/Hyp.
Cos A = 15/17
Sin A = 8/17
Repeating the same process for B, we have
Sin B = 11/61
adj² = hyp² - opp²
adj² = 61² - 11²
adj² = 3721 - 121
adj² = 3600
adj = √3600 = 60
Cos B = 60/61
Now, using the earlier stated trigonometric identity, we have
cos (a + b) = CosA CosB - SinA SinB
cos (a + b) = 15/17 * 60/61 - 8/17 * 11/61
cos (a + b) = 900/1037 - 88/1037
cos (a + b) = 812/1037

A jar contains only pennies, nickels, dimes, and quarters. There are 23 pennies, 22 dimes, and 20 quarters. The rest of the coins are nickels. There are 79 coins in all. How many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could you use to find n?
Answers
Answer:
1. 65 coins
2. 79 - (23 + 22 + 20) = n
Step-by-step explanation:
You can use the expression 23 + 22 + 20 to get the amount of coins that are not nickles. And for two? Try it yourself.

Elsa, Hans, and Charlie have a total of in their wallets. Hans has less than Elsa. Charlie has times what Hans has. How much do they have in their wallets?
Answers
Answer:
Elsa = x = $28
Hans = y = $26
Charlie = z = $56
Step-by-step explanation:
Elsa, Hans, and Charlie have a total of $106 in their wallets. Hans has $6 less than Elsa. Charlie has 2 times what Hans has. How much do they have in their wallets?
Let us represent.
The amount of money
Elsa = x
Hans = y
Charlie = z
Elsa, Hans, and Charlie have a total of $106 in their wallets.
= x + y + z = 106
Hans has $6 less than Elsa.
y = x - 6
Charlie has 2 times what Hans has.
z = 2x
Hence:
x + x - 6 + 2x = 106
4x - 6 = 106
4x = 106 + 6
4x = 112
x = 112/4
x = 28
Elsa = x = $28
Hans = y = $26
Charlie = z = $56

choice 4) x = 27, ∠FDG = 62°, ∠GOF = 118°
Step-by-step explanation:
2x + 8 + 4x + 10 = 180°
6x + 18 = 180
6x = 162
x = 27
∠FDG = 2(27) + 8 = 62°
∠GOF = 4(27) + 10 = 118°

The store paid 2.50 for a book and sold it 5.25%. What is the percent?
Answers
profit as a percent = (price sold - purchase price) / (purchase price)
profit as a percent = (5.25 - 2.50 ) / (2.50)
profit as a percent = 2.75 / 2.50
profit as a percent = 1.1
then we will multiply 1.1 by 100 to get a percentage
profit as a percent = 110%
