Mona wants to buy carpet for a floor in her house. The floor is rectangular with a width of 5 m and a length of 8 m. Two shops sell carpet with the prices shown below. How much will Mona save by going to Carpet World ?
Answers
Answer:
Mona will save a total of $7 by going to Carpet World.
Step-by-step explanation:
First, we need to calculate the total area of the floor by multiplying the width by the length...
5m * 8m = 40m
Now we calculate the amount that it would cost to buy the carpet from each of the establishments. For the first establishment, we can buy 16[tex]m^{2}[/tex] and get the next 8[tex]m^{2}[/tex] half off and that would leave another 16[tex]m^{2}[/tex] at full price. The second establishment we have a 5% off (0.95 of official price) for every 8[tex]m^{2}[/tex], since out total area is 5 times this amount then our total will have a 5% off.
Establishment 1: (16[tex]m^{2}[/tex] * 2.20) + (8[tex]m^{2}[/tex] * 1.10) + (16[tex]m^{2}[/tex] * 2.20) = $79.20
Establishment 2: (40[tex]m^{2}[/tex] * 1.90) * 0.95 = $72.20
Difference: 79.20 - 72.20 = $7
Mona will save a total of $7 by going to Carpet World.

Answer:
Step-by-step explanation:
A and B are the side lengths. C is the hypotenuse (the longest side).
For triangle A)
a^2+b^2=c^2
(it won't let me add exponents but you get the point)
4^2+2^2=c^2
8+4=c^2
12=c^2
c=square root of 12
For B)
a^2+b^2=c^2
2^2+5^2=c^2

After solving, it doesnt

Answers
Answer:
C
Step-by-step explanation:
The Pythagorean Theorem says [tex]a^{2} +b^{2} =c^{2}[/tex], with c being the hypothomes, which is not part of the right angle. So, when you square a and b, you get [tex]c^{2}[/tex]. To find the value of c, you find its square root.

Hu is installing a new window in his bedroom wall. He wants to center it horizontally. The window is 40 1/2 inches long, and the wall is 105 1/4 inches long. How far from each edge of the wall should Hu install the window? Type the number only, as a decimal or fraction. What is the answer?
Answers
Given :
Hu is installing a new window in his bedroom wall. He wants to center it horizontally.
The window is 40 1/2= 81/2 inches long, and the wall is 105 1/4= 421/4 inches long.
To Find :
How far from each edge of the wall should Hu install the window.
Solution :
Remaining size,
[tex]R = \dfrac{421}{4}-\dfrac{81}{2}\\\\R = \dfrac{259}{4}\ inches[/tex]
So, distance of the window form eah edge is [tex]\dfrac{R}{2}=\dfrac{259}{8}\ inches[/tex].
Hence, this is the required solution.

Rebekah manages a yoga studio that charges each customer a one-time initial fee of $35and an additional fee of $12per class taken. Rebekah's goal is for each customer to spend at least $100 at the studio, and she wants to know the minimum number of classes a customer needs to take to meet that goal.
Answers
Answer:
Step-by-step explanation:
12 x 5 = 60 + 35 = 85, and we cannot go any higher without exceeding 100. However it would be different if it was a decimal. So for now the answer would be 5 classes added with the initial one time fee of 35 dollars.
Miss Sullivan owns a farm where she has a total of 28 birds and dogs the total number of legs on those animals is 70 how many dogs and how many birds are on the farm
Answers
Answer:
21 birds and 7 dogs
Step-by-step explanation:
Represent Birds with B and Dogs with D
[tex]B + D = 28[/tex] ----- Total Animals
A bird has 2 legs and a dog has 4, so:
[tex]2B + 4D = 70[/tex] ---- Legs
Required
Solve for D and B
Make D the subject in the first equation
[tex]D = 28 - B[/tex]
Substitute 28 - B for D in the second
[tex]2B + 4(28 - B) = 70[/tex]
[tex]2B + 112 - 4B = 70[/tex]
Collect Like Terms
[tex]2B - 4B = 70 - 112[/tex]
[tex]-2B = -42[/tex]
Solve for B
[tex]B = -42/-2[/tex]
[tex]B = 21[/tex]
Recall that: [tex]D = 28 - B[/tex]
[tex]D = 28 - 21[/tex]
[tex]D = 7[/tex]
Hence, there are 21 birds and 7 dogs
