Answer:
the ladder is 5 ft from the base of the wall.
--
To find the unknown length, we need to use the Pythagorean Theorem
The Pythagorean Theorem is a²+b²=c²Since the legs are x and 12 this means that a=x and b=12
Also, since the hypotenuse is 13, this means that c=13.
Plug in a=x, b=12, c=13x²+12²=13²x²+144=169Subtract 144 from both sides.
x²=169-144Combine like terms.
x²=25Take the square root of both sides.
x=√25x=5 Simplify the square root.
Answer:
So the solution is x=5 which means that the foot of the ladder is 5 ft from the base of the wall.

the shoes department is offering a sale of 15% off all shoes. if mrs. jefferey saved $12.30, how much were the shoes full price?
Answer: $82
Step-by-step explanation:
F - .15F = 12.30
F = 12.3/.85 =$14.47 for full shoe price rounded down a fraction of a cent
Full Price minus 15% discount = $12.30
F - 0.15F = 12.30
F(1-0.15) = 12.30
0.85F = 12.30
Overall answer --->F = 12.30/.85 = 14.47058824

The two dot plots below compare the forearm lengths of two groups of schoolchildren:
Based on visual inspection of the dot plots, which of the following groups appears to have the longer average forearm length?
A. Group B, because a child in the group has the least forearm length of 11 inches
B. Group A, because three children in the group have the least forearm length of 11 inches
C. Group B, because four children have a forearm length longer than 13 inches
D. Group A, because no child in the group has a forearm length longer than 13 inches
So, The dots represent the children.
And the numbers represent the length in.
I wouldnt say its D.
I would say its C. Group B, because 4 kids have forearm length longer then 13 in.

Ricardo paid for 3 pounds of oranges with a $10 bill. He got back $8.20. What was the cost of 1 pound of oranges?
Answer:
6 cents
Step-by-step explanation:
10 - 8.20 = 1.8
1.8 / 3 = 0.6
Hope this helps you :D
Answer: $0.60
Step-by-step explanation:
Facts
got 3 lbs of oranges
paid with $10, got 8.20 in change.
Step 1: Find how much the 3lbs of oranges actually cost (actual total)
10-8.20= 1.8
Step 2: Find the unit rate (cost per lb)
Cost per lb. Divide the cost by the number of pounds, as shown:
1.8/3= 0.6
Step 3: Checks
[hypothetically], each pound costs 0.60.
Buying 3 pounds of oranges, multiply 0.6x3= 1.8.
Now, you pay with $10.
To find how much change you get, subtract 10-1.8= 8.20
These computations are correct, and the resulting facts match those given in the question. This is how I double check the answer is accurate.
Hence, each pound costs $0.60, or 60 cents.
Hope this helps :)) brainiest would be appreciated :D

Answer:
15d=165
Step-by-step explanation:
15 dollars per dough (d)= 165 dollars
Hope this helps! ;-)
~Master Chief
Let's solve this problem step by step:
So we know that Isaac sold 'x' number of tubs of dough
⇒ and that each tub of dough is worth 15 dollars
⇒ means he made '[tex]15*x'[/tex] dollars from selling 'x' tubs of dough
⇒ coincidently, we know that he made a total of $165
⇒ So the equation is: [tex]15x = 165[/tex]
Answer: 15x = 165
Hope that helps!

27. Find a polar equation of the conic with focus at the pole that has the given eccentricity and equation of directrix.
e=\frac{4}{3}, r \cos \theta=-3
The polar equation will be [tex]r=\dfrac{4}{1+cos\theta}[/tex]
What is the polar equation?A polar equation is any equation that expresses the relationship between r and theta, where r is the distance between the pole (origin) and a point on a curve, and theta is the counterclockwise angle formed by a point on a curve, the pole, and the positive x-axis.
From the equation, we are told that
The Eccentricity: e = 1
The Directrix is y = 4
Generally, the polar equation for e = 1 and y = + c is mathematically represented as
[tex]r =\dfrac{e\times c}{1+ecos\theta}[/tex]
[tex]r =\dfrac{1\times 4}{1+1\times cos\theta}[/tex]
[tex]r=\dfrac{4}{1+cos\theta}[/tex]
Therefore the polar equation will be [tex]r=\dfrac{4}{1+cos\theta}[/tex]
