A 3.6 metre long carpet that costs $67.14 expressed in$/m
Step-by-step explanation:
well, 3.6 meters cost $67.14
how much is 1 meter ?
right !
67.14 / 3.6 = $18.65
so, the price in $ per meter or $/m is $18.65.
For the function find f-1(x)
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solve for "y".
[tex]\stackrel{f(x)}{y}=\sqrt[3]{x^5-3}\implies \stackrel{\textit{quik switcheroo}}{x = \sqrt[3]{y^5-3}}\implies \stackrel{\textit{cubing both sides}}{x^3=y^5-3} \\\\\\ x^3+3=y^5\implies \sqrt[5]{x^3+3}=\stackrel{f^{-1}(x)}{y}[/tex]

Increase 835 in the ratio 7:5
Answer:
835.2
Step-by-step explanation:
Add the ratio together; 7+5=12
Divide; 835:12=69.5833333 / if needed, round the number with decimals -> 69.6
Multiply the number you have with each of the ratio numbers. 69.6×7=487.2 and 69.6×5=348
487.2+348=835.2

of cards you have
For each equation and graph, drag the situation that can be modeled by that
relationship into the space in that row.

You start with 1 card, and the number of cards triples each month.
You collect 3 cards each month.
The total cards equals the number of months multiplied by itself and then tripled.

a certain pet store sells only dogs and birds. They have a total of 71 animals in the store currently
A story employee walked around and counted a total of 246 legs. How many of the animals are
dogs?
Answer: 52 Dogs
Hi, I hope this helps you :D Good Luck !
Step By Step:
Let d = number of dogs
b = number of birds
d+b = 71
Birds have 2 legs and dogs have 4 legs
4d+2b = 246
Multiply the first equation by -2
-2d-2b = -142
Add this to the second equation
-2d-2b = -142
4d+2b = 246
--------------------------
2d + 0b = 104
Divide each side by 2
2d/2 = 104/2
d = 52
There are 52 dogs
what is equivalent to 4d-4?
Answer:
4 (d-1)

One weekend, 600 tickets were sold to a carnival for a total of $2400. If an adult's ticket costs $6 and a child's ticket costs $4, how many adults and how many children went to the carnival ?
Answer:
adults : 0 children: 600
Step-by-step explanation:
x + y = 600
6x＋4y = 2400
4×(x + y = 600) = 4x＋4y = 2400
(6x＋4y = 2400) － (4x＋4y = 2400) = x=0
so y=600

From a point T ,a man moves 12km due west and then moves 12km due south to another point Q. Calculate the bearing of T from Q
How to find the bearing between two points?
Let's assume that:
The point T is the point (0km, 0km).East is the positive x-axisNorth is the positive y-axis.Then, if the man moves 12 km due west and then 12 km due south, the new position is:
( 0km - 12km, 0km - 12km) = (-12 km, -12km)
This lies just in the middle of the third quadrant, so we have 90° per quadrant plus half of that:
90° + 90° + 45° = 225°
This is the angle measured from the positive x-axis, which is the east.
If we consider the negative x-axis, which is the west, the angle would be:
θ = 45°
This means that the bearing is 45° south of west.

what are 3 fractions that are greater than 1/2 but less than one (50 points)
Answer:
2/3, 3/4, and 4/5.
Step-by-step explanation:
Three fractions that are greater than 1/2 but less than 1 are 2/3, 3/4, and 4/5.
To write three fractions that are greater than 1/2 but less than 1, the following calculation must first be performed:
1/2 = 0.5
Therefore, the fraction must have a value between 0.5 and 1.
2/3 = 0.666
3/4 = 0.75
4/5 = 0.80
Therefore, three fractions that are greater than 1/2 but less than 1 are 2/3, 3/4, and 4/5.
Answer:
2/3, 3/4, and 4/5
