Answer:
4.75
Step-by-step explanation:
original price (100%) → $19
discounted price ((100-75)%) = (25%) → 25% x $19 = $4.75
Answer:
Step-by-step explanation:
Here's what we have to do:
1. 19 x 0.75
= 14.25
2. 19 - 14.25
= 4.75
3. 4.75 + 14.25
= $19
The Discount is $4.75, and the sale price is $19.00.

A recipe for sparkling lemonade calls for 4 tablespoons of lemonade mix and 12 cups of sparkling water. Find how many tablespoons of lemonade mix it takes per cup of sparkling water.
The ratio of lemonade and sparkling water is 1:3.
What is ratio?Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
Number of tablespoons of lemonade = 4,
And number of cups of sparkling water = 12.
To find tablespoons of lemonade pr cup of sparkling water,
Use ratio property,
= 4:12
=1:3
Therefore, 1 tablespoon of lemonade takes 3 cups of sparkling water.

Angela is riding a scooter around her neighborhood. The front wheel has a diameter of 10 inches and the back wheel has a diameter of 5 inches. The scooter is moving at a speed of 10 inches per second.
As she is riding her scooter, a spider hops onto the front wheel. Angela looks down and thinks that if the praying mantis has a good grip that he will go all the way around the wheel in just 1 second. Is Angela right or wrong? Why?
If she is wrong find the amount of time it will take to go all the way around
Answer:
i. Angela is wrong. Because the diameter of the wheel is not the distance covered all the way round.
ii. The time is 3.14 seconds.
Step-by-step explanation:
The font wheel has a diameter of 10 inches. Thus;
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{10}{2}[/tex]
= 5 inches
Circumference of a circle = 2[tex]\pi[/tex]r
⇒ The circumference of the front wheel = 2[tex]\pi[/tex]r
= 2 x [tex]\frac{22}{7}[/tex] x 5
= 31.4286
The circumference of the front wheel is 31.43 inches.
The total distance to be covered by the mantis = circumference of the front wheel
= 31.43 inches
But,
speed = [tex]\frac{distance}{time}[/tex]
The scooter moves with a speed of 10 inches per second, so that;
10 = [tex]\frac{31.43}{time}[/tex]
⇒ time = [tex]\frac{31.43}{10}[/tex]
= 3.143 s
The time taken to complete a revolution by the mantis is 3.14 seconds.
Therefore,
i. Angela is wrong. Because the diameter of the wheel is not the distance covered all the way round.
ii. The time is 3.14 seconds.

What is the equation of the line in slope-intercept form?
Answer:
y = 4/3 + 4
Step-by-step explanation:
4/3 comes from using rise over run. 4 comes from the y-intercept.
Answer:
y = [tex]\frac{4}{3}[/tex] x + 4
Step-by-step explanation:
y = mx + b
m = [tex]\frac{rise}{run}[/tex] ; "b" is y-intercept
~~~~~~~~~~~
m = [tex]\frac{4}{3}[/tex] and b = 4
y = [tex]\frac{4}{3}[/tex] x + 4

1. You purchase a car using a $15,000 loan with a 5% simple interest rate.
(a) Suppose you pay the loan off after 4 years. How much interest do you pay on your loan? Show your work. (10 points)
(b) Suppose you pay the loan off after 2 years. How much interest do you save by paying the loan off sooner? Show your work. ( 5 points)
Answer:
a) $3000
b) $1500
Step-by-step explanation:
a)
interest = Principal x rate as decimal x time
interest = 15,000 x 0.05 x 4
interest = 3000
b)
interest = Principal x rate as decimal x time
interest = 15,000 x 0.05 x 2
interest = 1500
you save $1500 if you pay after 2 years

Answer:
7) nth term a₁₈ is 160
8) nth term a₃₆ is 128
Step-by-step explanation:
7) Find nth term of each arithmetic sequence
[tex]a_1=7, d=9, n=18[/tex]
The formula used to find nth term is: [tex]a_n=a_1+(n-1)d[/tex]
Putting values and finding nth term n=18
[tex]a_n=a_1+(n-1)d\\a_{18}=7+(18-1)9\\a_{18}=7+(17)9\\a_{18}=7+153\\a_{18}=160[/tex]
So, nth term n₁₈ is 160
8) Find nth term of each arithmetic sequence
[tex]a_1=-12, d=4, n=36[/tex]
The formula used to find nth term is: [tex]a_n=a_1+(n-1)d[/tex]
Putting values and finding nth term n=36
[tex]a_n=a_1+(n-1)d\\a_{36}=-12+(36-1)4\\a_{36}=-12+(35)4\\a_{36}=-12+140\\a_{36}=128[/tex]
So, nth term n₃₆ is 128

if e^xy−y^2=e−4, then at x = 1/2 and y = 2, dy/dx =
Answer:
dy/dx = -0.5285
Step-by-step explanation:
e^(xy) − y² = e^(−4)
To get dy/dx, we will differentiate with respect to x applying both chain rule and product rule.
Thus;
e^(xy)[d(xy)/dx] - (d/dx)y² = 0
e^(xy)[x(dy/dx) + y] - ((dy/dx) × (d(y²)/dy)) = 0
xe^(xy)[dy/dx] + ye^(xy) - 2y = 0
Thus, rearranging we have;
dy/dx = [2y -(ye^(xy))]/xe^(xy)
We are given;
x = 1/2 and y = 2
Thus;
dy/dx = [2(2) - (2e^(½ × 2))]/(1e^(½ × 2))
dy/dx = (4 - 5.4366)/2.7183
dy/dx = -0.5285

What are Exponents?Exponents are the method of writing numbers, especially large numbers, in terms of a base and an exponent, which is written as the power of base.
Given that,
5⁵ . 5ˣ = 5²
We have to use a multiplication rule for exponent here.
xᵃ . xᵇ = xᵃ⁺ᵇ
Using this,
5⁵⁺ˣ = 5²
⇒ 5 + x = 2
⇒ x = -3
p⁻³ . p⁻⁶ = p^y
Using the same rule of exponent,
p⁻³⁺⁻⁶ = p^y
⇒ y = -3 - 6 = -9
9² . 9⁻⁷ . 9ⁿ = 9⁻⁵
9²⁻⁷⁺ⁿ = 9⁻⁵
⇒ 2 - 7 + n = -5
⇒ n = 0
Hence the values of x, y and n are -3, -9 and 0 respectively.
