Answer:
The answer is below
Step-by-step explanation:
a) Let y represent the amount of time kiran slept, hence:
y = x - (1/10)x = x - 0.1x
y = 0.9x
b) Let y represent the amount of time Mia practice, hence:
y = x - (2/5)x = x - 0.4x
y = 0.6x
c) Let y represent the amount of drink kiran drank, hence:
y = x + (4/3)x = 7x / 3
y = 7x/3
d) Let y represent the money Mai spent, hence:
y = x - (1/4)x = x - 0.25x
y = 0.75x
e) Let y represent the amount of almond kiran ate, hence:
y = x + 1.5x = 2.5x
f) Let y represent the recycling Mai collected, hence:
y = x - (3/10)x = x - 0.3x
y = 0.7x
g) Let y represent the amount of km kiran walked, hence:
y = x + (3/8)x
y = (11/8)x
h) Let y represent the amount of puzzles mai completed, hence:
y = x + (3/5)x = x + 0.6x
y = 1.6x

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!!

Answer:
4^3, 8^2, 2^6
Step-by-step explanation:
64^1 = 64
We need all expressions equal to 64.
4^3 = 4 * 4 * 4 = 64 Yes
3^4 = 3 * 3 * 3 * 3 = 81 No
8^2 = 8 * 8 = 64 Yes
2^8 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 256 No
6^2 = 6 * 6 = 36 No
2^6 = 2 * 2 * 2 * 2 * 2 * 2 = 64 Yes
Answer:
Step-by-step explanation:
1,3, and 6 are the correct answers.
when you see a small number next to the big number that means you multiply that big number how ever much the small number shows

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.

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

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.

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
