90% OFF original price!
Eric wants to buy a chandelier. The original price is $90. What is the sale price?
$
90% of $90 is $81, so therefore the sale price (original price - percentage) would be $9.
(1+3p)(1-3p)
the answer is 1-9p²
How do i get this though?
Step-by-step explanation:
[tex](a - b)(a + b) = {a}^{2} - {b}^{2} [/tex]
simplify the product and you get
[tex] {1}^{2} - (3p {}) {}^{2} [/tex]
1 times any power automatically equals 1. So that equals
[tex]1 - (3p) {}^{2} [/tex]
=
[tex]1 - 9p {}^{2} [/tex]

A park volunteer plans to work on the park's stone walls for 1 hour every Monday, 1 hour every
Wednesday, and 3 hours on Fridays. The graph shows the number of hours he plans to work for a
given number of weeks. Complete parts a through c.
Answer:
The answer is below
Step-by-step explanation:
A linear graph has an equation in the form y = mx + b, where y and x are variables, m is the slope of the line and b is the y intercept (that is value of y at x = 0).
a) y represent the number of hours worked and x represent the number of weeks. The points are represented in the form (x, y).
First we can find the slope of the line by picking two points from the graph. Let us use (0, 0) and (2, 10). The slope m is given as:
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{10-0}{2-0} \\\\m=5[/tex]
The slope and constant of proportionality is 5.
b) The equation can be gotten using the points (0, 0) and (2, 10). Therefore:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\\\y-0=\frac{10-0}{2-0}(x-0)\\\\y=5x\\\\[/tex]
c) In 16 weeks (i.e. x = 16):
y = 5x
y = 5(16)
y = 80 hours

Which is an equation of the line with a slope of 4 and a y-intercept of -2?
Answer:
y = 4x - 2
Step-by-step explanation:
Y-intercepts cross the y-axis at x = 0. So, we can plug (0 , -2) into an equation with m = 4.
-2 = 4(0) + b
-2 = b
y = 4x - 2

Juanita is buying a cover for her motorcycle which has a length of 7.5 feet if the covers are only sold in whole foot increments what size covers should Juanita buy
Answer:
Size of the cover should Juanita buy is 8 feet.
Step-by-step explanation:
Given: The length of the motorcycle is 7.5 feet.
To find: The size of the cover of motorcycle.
The length of the motorcycle is 7.5 feet. But the covers are only sold in whole foot increments.
So, Juanita should buy 8 feet long cover for motorcycle.
In A ABC, m ZA = 36°, m ZB = 45°, and m ZC = 99º. Which statement
is true?
A. CA > BC > AB
B. BC > CA > AB
C. AB > BC > CA
D. AB > CA > BC
Answer:
The true statement is AB > CA > BC ⇒ D
Step-by-step explanation:
In any triangle, the longest side in length is the opposite to the greatest angle in the measure, and the shortest side in length is opposite to the smallest angle in the measure.
Let us solve the question
∵ ABC is a triangle
∵ m∠A = 36°
∵ m∠B = 45°
∵ m∠C = 99°
→ That means C is the greatest angle and A is the smallest angle
∴ ∠C is the greatest angle and ∠A is the smallest angle
∴ The arrange of the measures of the angles is m∠C > m∠B > m∠A
∵ AB is the opposite side of ∠C
∴ AB is the longest side
∵ BC is the opposite side of ∠A
∴ BC is the shortest side
∵ CA is the opposite side of ∠B
∴ The arrange of the lengths of the sides is AB > CA > BC
∴ The true statement is AB > CA > BC
A runner has a mass of 89 kg he produces aforce of 84 Newtons between the ground and his running shoes How fast does he accelerate
Force = mass × acceleration
acc= force / mass
84N/89kg
= 0.94m/s
The acceleration of the runner is 0.9 m/[tex]s^{2}[/tex].
We have a runner has a mass of 89 kg he produces a force of 84 Newtons between the ground and his running shoes.
We have to determine the acceleration of the runner.
What is the formula to calculate the force on a body ?The force on a body is the product of mass and acceleration. Mathematically -
F = ma
According to the question, we have -
Force = 84 N
Mass = 89 Kg
Therefore -
F = ma
84 = 89 x a
a = 84/89 = 0.9 m/[tex]s^{2}[/tex]
Hence, the acceleration of the runner is 0.9 m/[tex]s^{2}[/tex].

Angela purchased a storage cube with a volume of 10 cubic feet. She wants to put it on a shelf that is 24 inches tall.
A.
Yes, because the height of the cube is approximately 4.93 inches.
B.
Yes, because the height of the cube is approximately 2.15 inches.
C.
No, because the height of the cube is approximately 25.85 inches.
D.
No, because the height of the cube is approximately 39.96 inches.
Answer:
c
Step-by-step explanation:
10 cubic feets volume is equivilant o 25.85 inches.
No, because the height of the cube is approximately 25.85 inches. Option C is correct.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing. A cube's volume can be calculated using its side cube.
Given that, Angela bought a storage unit with a 10 cubic foot capacity. It will go on a shelf that is 24 inches tall,
Volume, V = 10 cubic feet
Height, h =24 inches
The volume of a cube is found as the cube of the side.
Volume of cube = side³
V=a³
10=a³
Take a cube root of 10 to find the value of a,
a=2.15 feet
We can convert feet into inches, in one foot there are 12 inches.
1 feet = 12 inches
2.15 feet = 2.15 × 12
2.15 feet = 25.85 inches
Thus, no because the height of the cube is approximately 25.85 inches. Option C is correct.

(3x+23x +32) = (x+6)
Answer:
x = -26/25
Step-by-step explanation:
(3x+23x +32) = (x+6)
Combine like terms
26x +32 = (x+6)
Subtract x from each side
26x -x +32 = x+6-x
25x +32 = 6
Subtract 32 from each side
25x+32 -32 = 6-32
25x = -26
Divide each side by 25
25x/25 = 26/25
x = -26/25
