Laura collects nickels and dimes she has a total of 47 nickels and dimes she calculated the value of the coins and found out she has $4.05 how many nickels and dimes does laura
Answer:
Number of dimes = 34
Number of nickels = 13
Step-by-step explanation:
Total number of coins = 47
Coins are in the form of nickels and dimes.
Value of a nickel = 5 cents
Value of a dime = 10 cents
Total value of coins = $4.05 or 405 cents
To find:
Number of nickels and dimes?
Solution:
Let number of nickels = [tex]x[/tex]
Money value of nickels = 5[tex]x[/tex]
Let number of dimes = [tex]y[/tex]
Money value of dimes = 10[tex]y[/tex]
Total value of coins = [tex]5x+10y[/tex]
This value is given as equal as 405.
As per question statement, the equations can be written as:
[tex]5x+10y = 405 ..... (1)\\x+ y = 47 ...... (2)[/tex]
Multiplying equation (2) with 5 and subtracting from equation (1):
[tex]10y - 5y = 405 - 235 \\\Rightarrow 5y = 170\\\Rightarrow y = 34[/tex]
Number of dimes = 34
Number of nickels = 47 - 34 = 13

find the missing side measure
Answer:
D) 25.5
Step-by-step explanation:
Use basic trigonometry. In this case, use sine.
sin(45) = 18 / x
18 / sin(45) = x
x = 25.4558441227
After you solve this, you will see that 25.5 is close to that.
Hence, the answer to this question is D.

Exit Ticket: At noon, a tank has a water depth of 9 in. After 3 hours, the depth was 8 inches. At 6pm, the depth was 7 inches. What is the initial value for the function? help will be appreciated.
Answer:
Step-by-step explanation:
The straight line equation is:
y = m*x + b Where m is the slope of the line and b the intercept with y-axis, in our case y is the depth of the tank and x (time in lapsus of 3 hours).
The slope m = ( y₂ - y₁ ) / (x₂ - x₁)
We have point A ( 3 , 8 ) and point B ( 6 , 7 )
m = ( 6 - 3 ) / (7 - 8 ) m = -3
We see that each 3 hours time-depth decreases 1 in.
Then to find the depth at the beginning of x-axis
At noon 12 tank was 9 inches, three hours before at 9 in the morning the depth was 10 inches and:
9 in the morning 10
6 in the morning 11
3 in the midnight 12
12 in the night 13
Then 13 is the intercept with y-axis
then the equation is:
h = - 3*x + 13
Note x is time in lapsus of 3 hours

Given
- 4(- x + 8) = 0
- 4≠ 0, so
- x + 8 = 0 ( subtract 8 from both sides )
- x = - 8 ( multiply both sides by - 1 )
x = 8
Answer:
X=8

Answer:
Step-by-step explanation:
Equation for the linear function has been given as,
y = 26 - 4x
For x = 1,
y = 26 - 4(1)
= 26 - 4
= 22
For x = 2,
y = 26 - 4(2)
= 26 - 8
= 18
For x = 3,
y = 26 - 4(3)
= 26 - 12
= 14
For x = 6,
y = 26 - 4(6)
= 26 - 24
= 2
Therefore, table for the function will be,
x y

2 18

Clara simplifies (8 b minus 4 r) minus (2 b minus r) and says the result is 6 b minus 5 r. What error did Clara make?
Answer: Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b minus 3 r.
Step-by-step explanation: (8b-4r)-(2b-r)
Open the bracket
=8b-4r-2b+r
Collect the like terms and simplify
=8b-2b-4r+r
=6b-3r
Clara incorrectly combined the r coefficients. The correctly simplified expression is 6 b minus 3 r.
