Answer:
The value is [tex]t_2 = 50 \ minutes[/tex]
Step-by-step explanation:
From the question we are told that
The driving time varies inversely with the speed of the car
The amount of time a trip at a velocity of [tex]v_1 = 50 \ mph[/tex] takes is [tex]t_1 = 40[/tex]minutes
Let
v represent the velocity
while t represent the time
So
[tex]t \ \ \alpha \ \ \frac{1}{v}[/tex]
=> [tex]t \ \ = k \ \ \frac{1}{v}[/tex]
=> [tex]k = vt[/tex]
=> [tex]v_1 * t_1 = v_2 * t_2[/tex]
From the question we are given [tex]v_2 = 40 \ mph[/tex] and we are told to find [tex]t_2[/tex]
So
[tex]t_2 = \frac{v_1 * t_1}{v_2}[/tex]
=> [tex]t_2 = \frac{ 50 * 40}{40}[/tex]
=> [tex]t_2 = 50 \ minutes[/tex]
This is pretty easy but I’m just bad at explaining it if u know ur inequalities please help.
Caleb is saving money to buy a bike next year. He makes $75 per week babysitting. So far he has saved $150. Write an inequality to show how many weeks he must babysit so he has at least $800 to spend on the bike, then solve the inequality.
Answer:
x>8.6
Step-by-step explanation:
We want to model an expression for the amount of money Caleb has and how many week he must work to have that amount
given data
amount at hand=$150
weekly saving=$75
let the number of weeks be x
total amount= $800
the expression for this situation is given as
y=mx+c
where y=800
m=75
c=150
substituting we have
800=75x+150
solving for x we have
800-150=75x
650=75x
x=650/75
x=8.6
then he must work for x>8.6 weeks

what is the original slope and the parallel slope
Hey there!
Answer:
Original slope: [tex]\frac{-3}{1}[/tex]
Parallel slope: [tex]\frac{-3}{1}[/tex]
Step-by-step explanation:
The slope of this line looks like its [tex]\frac{-3}{1}[/tex], and parallel lines are lines that will never intersect, which means they will always have the exact same slope! Hope this helps! :)

What is p in p+5=p+6 it doesn’t make sense to me
Answer:
no solution
Step-by-step explanation:
Given
p + 5 = p + 6 ( subtract 5 from both sides )
p = p + 1 ( subtract p from both sides )
0 = 1 ← not possible
Because it makes no sense the equation has no solution

Edward purchased his home for $89,000. For the first three years after he moved in the real estate market was very lively, so his property value grew by 4.8% every year. For the next five years, the market slowed down somewhat, and his property value grew by 2.6% every year. How much had the value of Edward's home increased after eight years, to the nearest hundred dollars?
a. $25.700
b. $27.500
c. $30,000
d. $13,200
Answer:
b
Step-by-step explanation:
After eight years, the value of Edward's home increased by $24,386.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
We have to given that;
Edward purchased his home for $89,000.
For the first three years after he moved in the real estate market was very lively, so his property value grew by 4.8% every year.
And, For the next five years, the market slowed down somewhat, and his property value grew by 2.6% every year.
Now,
After three years, the value of Edward's home increased by,
⇒ 3 × (4.8% of $89,000)
⇒ 3 × (4.8/100 × 89,000)
⇒ 3 × 4,272
⇒ $12,816
And, After five years, the value of Edward's home increased by,
⇒ 5 × (2.6% of $89,000)
⇒ 5 × (2.6/100 × 89,000)
⇒ 5 × 2,314
⇒ $11,570
Thus, After eight years, the value of Edward's home increased by,
⇒ $12,816 + $11,570
⇒ $24,386

Rewrite 3^-7 using a positive exponent.
Answer:
1/3^7
Step-by-step explanation:
Negative exponents go to the denominator
The positive exponent for the given exponent is [tex]\frac{1}{3^7}[/tex].
The given exponent is [tex]3^{-7}[/tex].
What is an exponent?The exponent of a number shows how many times the number is multiplied by itself.
A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number.
Now, [tex]3^{-7}=\frac{1}{3^7}[/tex] (∵[tex]a^{-n}=\frac{1}{a^n}[/tex])
Therefore, the positive exponent for the given exponent is [tex]\frac{1}{3^7}[/tex].
