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

AB = p
AD = 9
DC AB = 3:2
D
С
a) Write vector DC in terms of p.
+
b) Work out vector BC in terms of p and q.
Give your answer in its simplest form.
Answer:
a) 2/3pb) q + 1/2pStep-by-step explanation:
Given
AB = pAD = qa)
DC /AB = 3/2 ⇒ DC = 3/2AB = 3/2pb)
BC = AD + (DC - AB)BC = q + (3/2p - p) = q + 1/2pAnswer:
a) DC=1.5p
b) q=0.5p

Ahmad just bought a used sailboat with two sails that need replacing. How much sail fabric will Ahmad need if he replaces sail A?
PLZ HELP
Answer:
sail a = 81ft²
sail b base = 12ft
Step-by-step explanation:
question 5:
the measurements for sail A are 18ft(height) and 9ft (base)
the formula to find the the area of a triangle is (b · h) 1/2
(9 · 18) 1/2 = (162) 1/2 = 81
so ahmad will need 81ft² of fabric for sail a
question 6:
we know that the formula to find the area of a triangle is (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.
(b · 18) 1/2 = 108
[tex]\frac{(b . 18) 1/2}{1/2}[/tex] = 108/ 1/2
(b · 18) = 216
18b = 216
18b/18 = 216/18
b= 12
check your work:
(12 · 18) 1/2 = 108
(216) 1/2 = 108
108 = 108 true!
the base measurement for sail b is 12ft
hope this helps and have a great day!!
7th grade math help pls it’s about slope and stuff
Answer:
m=-2
entire equation in slop int. form is: 7=-2x+5
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.

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.

Plz helppp meee wallah I swear to god I will mark you as a brainliest and I will give you 20
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
1 22
2 18
3 14
6 2
