Mr. Armstrong went to Target to buy four pairs of dress socks. There was a 30% off sale
on the socks, and his total bill before tax was $14. What was the price of each pair of socks
before the sale?
Answer: $5
Step-by-step explanation:
We should note that since there was a 30% off sale, it means that he paid for 70% (100% - 30%) of the sales price.
Therefore, let the price of the socks be represented as x.
70% of x = 14
70/100 × x = 14
0.7 × x = 14
0.7x = 14
x = 14 / 0.7
x = 20
Therefore, the price of the socks was $20. Since there are 4 pairs, each pair will be:
= $20 / 4
= $5

Write an equation whose graph is a line perpendicular to the graph of x = -7 and which
passes through the point (-7,1).
Answer:
y = 1
They will pass through each other perpendicular, also you can look up graph in chrome and use a free graph.
Step-by-step explanation:
The equation of the line perpendicular to the graph of x = -7 and which passes through the point (-7,1) is y=1.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
As the equation x=-7 will represent a straight verticle line at x=-7. Therefore, the line that will perpendicular to this line will be a horizontal line. Since it is given that the line must intersect at (-7,1). The horizontal line should be at y=1.
Hence, the equation of the line perpendicular to the graph of x = -7 and which passes through the point (-7,1) is y=1.

A ball is thrown into the air with an upward velocity of 44 ft/s. It’s height h in feet after t seconds is given by the function h=-16t^2 +44t+5. How long does it take the ball to reach its maximum height? What is the balls maximum height?

Answer:
1.375 seconds35.25 feetStep-by-step explanation:
A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).
Here, we have ...
h = -16t^2 +44t +5
t = -44/(2(-16)) = 11/8 = 1.375
It takes 1.375 seconds for the ball to reach its maximum height.
The height at that time is ...
h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25
The maximum height is 35.25 feet.

Answer:
x = 3, y = 30.4
Step-by-step explanation:
From the given diagram;
8x - 3 = 6x+3 (alternate exterior angle are equal)
Collect like terms
8x - 6x = 3 + 3
2x = 6
x = 6/2
x = 3
Also;
8x - 31 + 5y + 35 = 180 (sum of angle on a straight line is 180)
8(3) - 31 + 5y + 35 = 180
5y + 24 - 31 + 35 = 180
5y + 28 = 180
5Y = 180 - 28
5Y = 152
y = 152/5
y = 30.4
Hence x = 3, y = 30.4

sinB = 5/13, cosB = 5/13, tanB = 5/12
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
Sin(A) = 12/13
Sin(B) = 5/13
Cos(A) = 5/13
Cos(B) = 12/13
Tan(A) = 12/5
Tan(B) = 5/12

A Ferris Wheel has a radius of 16 feet. How far will you travel if you take a ride that goes around 5 times? Round answer to the nearest hundredth and for pi use π = 22 7 .
Answer:
502.85 feet
Step-by-step explanation:
Given that,
The radius of a Ferris wheel, r = 16 feet
We need to find how far will you travel if you take a ride that goes around 5 times.
Distance = 5×2πr
So,
= 10πr
[tex]=10\times \dfrac{22}{7}\times 16\\\\=502.85\ \text{feet}[/tex]
So, the required distance is 502.85 feet.
Savannah has a principle of 15000 with a 4.25% and saves 1,275 in interest. How long is she saving for
Answer:
5.73 years
Step-by-step explanation:
Considering she saved 4.25% in each year of the amount $15000.
So, we have to calculate in what time her saving reaches $1275, if she save each year.
it becomes question of simple interest in which
SI = $1275, Principal P= $5000, time T, rate R = 4.25%
we know SI = PRT/100
1275 = 5000×4.25×T/100
⇒T = 1275×100/(5000×4.25)
⇒ T= 5.73 years
