A tool set is on sale for 424.15. The original price of the tool set was 499.00. What percent of the original price is the sale price?
How do you solve this?
Answer:
499-424.15=74.85
499:100=4.99
74.85:4.99=15 is the percent of the discount
100-15=85 is the percent of the original price that you pay

Answer:
(5, -7) is the center 9 is the radius
Step-by-step explanation:
just a general rule >>
(x-h)^2 + (y-k)^2=r^2
r^2 is 81 so the radius is 9
notice its -h and -k, so the actual answers are the negate of whatever is in the parentheses
-5 is actually 5
and 7 is actually -7
(5, -7)
pls give brainliest!!
can y’all please help. I will send points if you want me to.

Eric's house is in the same quadrant as the library. Which of the following could be the coordinates of Eric's house?
(2,4)
(-2,4)
(2,-4)
(-2,-4)
Answer:
if Eric house is in the same quadrant as the library then the coordinates will be (-2,4)
Answer:
(-2, 4) is also in the second quadrant
Step-by-step explanation:
The library is in the second quadrant, at the point (-3, 5), where the x-coordinate is negative and the y-coordinate is positive. Among the four given points, only (-2, 4) is also in the second quadrant.

Answer:
[tex]c = \sqrt{52}[/tex]
Step-by-step explanation:
[tex]c^{2} = a^{2} + b^{2}[/tex]
[tex]c^{2} = 4^{2} + 6^{2}[/tex]
[tex]c^{2} = 16 + 36\\[/tex]
[tex]c^{2} = 52[/tex]
[tex]\sqrt{c^{2} } = \sqrt{52}[/tex]
[tex]c = \sqrt{52}[/tex]
All of the edges of a regular triangular pyramid have length 12. A frustum of the pyramid has height half of that of the pyramid. What is the:
1) Volume of the frustum?
2) Surface area of the frustum?
Answer:
1) The volume of the frustum is 27·(√3)·h
2) The surface area the frustum is 24·h + 54·√3
Step-by-step explanation:
1) A frustum of the regular triangular prism is a portion of the triangular prism
The length of the edge of the triangle prism = 12
The area of the triangular face, A = (√3/4)·a²
∴ A = (√3/4)·12² = 36·√3
When
The volume of the triangular prism, V = A·h = (36·√3)·h
By triangle proportionality theorem, the cross sectional area of the top half of the triangular prism = (√3/4)·6² = 9·(√3)
The volume of the top half, V₂ = 9·(√3)·h
The volume of the frustum = V - V₂ = (36·√3)·h - 9·(√3)·h = 27·(√3)·h
The volume of the frustum = 27·(√3)·h
2) The surface area of the triangular side of the frustum is given as follows;
A = 36·√3- 9·(√3) = 27·(√3)
The surface area the frustum, [tex]F_A[/tex] = 2×27·(√3) + 2 ×6 ×h + 12×h = 24·h + 54·√3
The surface area the frustum = 24·h + 54·√3
Ava makes bead necklaces. She has a total of write the value of each expression.of 6,048 beads. Each necklace has 24 beads.Her friend Maria says that the greatest number of necklaces she can make with the beads is 162. Maria’s work is shown here.Explain why Maria’s answer is incorrect and how she can find the correct answer.
Answer:
She made the 6 into a five to make the 0 a 1 too early, because 24 can go into 60 twice, but in order to subtract the 8, you would then have to make the 6 into a 5 as well as the 0 into a 1.
Step-by-step explanation:
6048 divided by 24 is 252

Answer:
30.45
Step-by-step explanation:
Answer:
30.45
Step-by-step explanation:
if
[tex]a = \frac{2x + \sqrt{x} }{x} [/tex]
and
[tex]b = \frac{1 - 2 \sqrt{x} }{ \sqrt{x} } [/tex]
without sing a calculator, show that
[tex](a + b) {}^{2} = \frac{4}{x} [/tex]
Answer:
Step-by-step explanation:
Rationalize the denominator of b. So, multiply the numerator and denominator by [tex]\sqrt{x}[/tex]
[tex]b = \frac{(1-2\sqrt{x}) *\sqrt{x}}{\sqrt{x}*\sqrt{x} }=\frac{1*\sqrt{x} -2\sqrt{x} *\sqrt{x} }{\sqrt{x} *\sqrt{x} }\\\\=\frac{\sqrt{x} -2x}{x}\\[/tex]
Now, find a +b
[tex]a +b = \frac{2x+\sqrt{x} }{x}+\frac{\sqrt{x} -2x}{x}\\\\=\frac{2x+\sqrt{x} +\sqrt{x} -2x}{x}[/tex]
Combine like terms
[tex]= \frac{2x-2x+\sqrt{x} +\sqrt{x} }{x}\\\\=\frac{2\sqrt{x} }{x}[/tex]
Now find (a + b)²
(a +b)² = [tex](\frac{2\sqrt{x} }{x})^{2}[/tex]
[tex]= \frac{2^{2}*(\sqrt{x} )^{2}}{x^{2}}\\\\= \frac{4* x}{x^{2}}\\\\= \frac{4}{x}[/tex]
Hint: [tex]\sqrt{x} *\sqrt{x} =\sqrt{x*x}=x[/tex]

[tex]\sqrt[4]{7m} = (7m)^\frac{1}{4}[/tex]'
Step-by-step explanation:
Given
[tex]\sqrt[4]{7m}[/tex]
Required
Write using rational exponent
[tex]\sqrt[4]{7m}[/tex]
Law of indices states that:
[tex]\sqrt[n]{a} = a^\frac{1}{n}[/tex]
Apply this law on: [tex]\sqrt[4]{7m}[/tex]
We have:
[tex]\sqrt[4]{7m} = (7m)^\frac{1}{4}[/tex]
