A collection of nickels and quarters is worth $2.10. There are 22 coins in all . How many of each coin
are there?
Answer:
17 nickels
5 quarters
Step-by-step explanation:
Let n = no. of nickels
22 - n = no. of quarters
Each quarter is 25 cents and each nickel is 5 cents
5n = total amount of money in cents for the nickels
25(22 - n) = total amount of money in cents for the quarters
Since the total amount of money is $2.10 or 210 cents we have the equation
5n + 25(22 - n) = 210
5n + 550 - 25n = 210
-20n + 550 = 210
-20n = -340
n = 17 nickels
22 - n = 22 - 17 = 5 quarters
Now, you don't need to do all that I did. I explained in detail what is going on in this problem. All that you would need to do is write this:
let n = no. of nickels
22 - n = no. of quarters and then write the equation and solve
5n + 25(22 - n) = 210
?? OK?

Answer:
On a coordinate plane, a straight line has a positive slope and goes through (negative 3, negative 3), (0, 0), and (3, 3).
Step-by-step explanation:
If f(x) and g(x) are inverse functions, then f(g(x)) = x
The graph of y = x goes thru points with the coordinates of x and y being equal. So, the second answer is correct

Find the value of the lettered angles in each of the following ( see image ).
Please show workings.
The only given angles are 60° , 10° , 40°
Answer:
Step-by-step explanation:
s + 40 + 60 = 180 {angle sum property}
s + 100 = 180
s = 180 - 100
s = 80
This figure is a cyclic quadrilateral. sum of opposite angles are 180
s + v + 60 + 10 = 180
80 + v + 60 + 10 = 180
v + 150 = 180
v = 180 - 150
v = 30
y+ 10 + v = 180 {angle sum property}
y + 10 + 30 = 180
y + 40 = 180
y = 180 - 40
y = 140
9514 1404 393
Answer:
r = 80°, s = 80°, t = 10°, u = 60°, v = 30°
Step-by-step explanation:
Working clockwise from the left side, we can name the points on the circle as A, B, C, D. The given inscribed angles are half the measure of the arcs they intercept, so we have ...
arc BD = 2×40° = 80°
arc DA = 2×60° = 120°
arc CD = 2×10° = 20°
From these measures, we can deduce the measures of the individual arcs as ...
arc AB = 360° -BD -DA = 360° -80° -120° = 160°
arc BC = BD -CD = 80° -20° = 60°
Then the angle measures of interest are ...
r = AB/2 = 80°
s = AB/2 = 80°
t = CD/2 = 10°
u = DA/2 = 60°
v = BC/2 = 30°

can someone help find x, y, and z
Answer:
Step-by-step explanation:
x^2=13^2-12^2
x^2=25
x=5
(sin90)/13=(sin(90-A))/5
sin(90-A)=5/13
90-A=arcsin(5/13)
A=90-arcsin(5/13)
tan(90-arcsin(5/13))=5/y
y=5/(tan(90-arcsin(5/13))
y=25/12

Step-by-step explanation:
a sum of money was divided between two friends, karen and Natasha in the ratio 2:5. If Natasha received $120 more than karen, find the sum of money shared
Answer:
$600
Step-by-step explanation:
Let x be the total amount divided
Karen gets (2/7) x
Natasha gets (5/7) x
(5/7) x = (2/7) x + 210
Multiply both sides by 7
5x = 2x + 1470
3x = 1470
x = 490
Natasha gets (5/7) (490) = 350
Karen gets (2/7)(490) = 140
The difference in ration is 5 - 3 = 2. So divide 150 by 2 to get the amount for each part of the ratio which is 75. the total ration is 3 + 5 = 8. So to get the total original sum of money, multiply 75 and 8 which is $600. for each person just multiply 75 with their respective ratios. For A: 75 X 3 = $225. For B: 75 x 5= $375. To check that it is correct add 225 and 375, and you should get 600.
according to my calculations, the starting amount will be 600
Answer:
$280
Step-by-step explanation:
Ratio = 2 : 5
Karen's Share = 2x
Natasha's share = 5x
Natasha received $120 more than karen.
5x = 2x + 120
5x - 2x = 120
3x = 120
x = 120/3
x = 40
Karen's share = 2*40 = $ 80
Natasha's share = 5*40 = $ 200
Sum of money = 80 +200 = $ 280
