Answer:
The value of y is directly proportional to the value of x. When x = 4.25, the value of y is 2. What is the value of x when y = 8?
Step-by-step explanation:
Answer:
x = 17 when y = 8
Step-by-step explanation:
Considering the value of y,
→ 8 ÷ 2
→ 8/2 = 4
Now the value of x will be,
→ x = 4.25 × 4
→ [ x = 17 ]
Hence, the value of x is 17.
In a laboratory experiment, the population of bacteria in a petri dish started off at
2600 and is growing exponentially at 13% per day. Write a function to represent the
population of bacteria after t days, where the hourly rate of change can be found
from a constant in the function. Round all coefficients in the function to four decimal
places. Also, determine the percentage rate of change per hour, to the nearest
hundredth of a percent.
Answer:
See belowStep-by-step explanation:
Daily growth rate is 13% with initial values of 2600 bacteria.
The equation is:
[tex]f(t) = 2600*( 1 + 0.13)^t=2600*1.13^t[/tex]Find the hourly rate x considering 1 day = 24 hours:
[tex]2600*1.13^{t/24}=2600*x^t[/tex][tex]ln 1.13^{t/24}=ln x^t[/tex][tex]ln1.13^{1/24}=lnx[/tex][tex]x=1.13^{1/24} =1.0051[/tex]Percentage rate of change per hour is:

Danielle bought a silver coat rack online it cost $653.76 +7% shipping and handling what was the total cost
round your answer to the nearest cent
Answer:
$699.52
Step-by-step explanation:
Theres two ways to solve this.
(1) You can either find 7 percent of 653.76 and then add it on
or
(2) You can just multiply the tax with the 653.76
Option (1)
You find 7 percent of 653.76. Now percent means out of a hundred so 7 percent is really 7/100 or 0.07
Now you multiply 653.76 by 0.07 which is 45.76 (rounded to nearest cent)
Now add it up to the total.
653.76+45.76= $699.52
Option (2)
This is the easier method in my opinion. SInce you want to find the total of the product including tax. The tax is technically multiplying the total. The total of course is 653.76 and total means everything. Everything means 100%. So you can add 100% to the tax cause technically thats what your doing becuase you grinding 7percent of the total which is 100 percent. So in this case your price is increasing by 107 percent.
(Example)
So If you want to find 100 percent of a product it would be the same exact result. Like 100 percent of 653.76 is 654.76… So using that we can just add the amount of tax to the 100%. 100+7=107%
Proof that this works is this
usually when you want to find a percentage of something, you turn the percentage into a decimal then multiply. So 100 percent of 653.76 is 653.76*1.00 which is 653.76. So the 100 percent is a place holder to prevent you from doing more steps. Now just add 7 percent since your increasing the total by 7 percent (tax). Now its 653.76*1.07 which when solved you would get $699.52. The same exact result. Less steps same result.
Final answer: $699.52
How do you do Geometry the right way and what is the best way to remember how to do it?

Answer:
7.5
Step-by-step explanation:
To find the area of a trapezoid it is:
[tex]A= \frac{a+b}{2}h[/tex]
Where h is the height, b is the base, and a is the "top base," so our values are:
h = 5
b = 9
a = 6
Plug them in and solve:
[tex]A= \frac{a+b}{2}h[/tex]
[tex]A= \frac{6+9}{2}5[/tex]
[tex]A= \frac{15}{2}5[/tex]
[tex]A = (7.5)(5)[/tex]
[tex]A = 37.5[/tex]
The area of the rectangle is found by using:
[tex]A=bh[/tex] where b is the base and h is the height. So our values are:
b = 6
h = 5
Plug in and solve:
[tex]A=bh[/tex]
[tex]A=(6)(5)[/tex]
[tex]A = 30[/tex]
Subtract the rectangle from the trapezoid:
37.5 - 30 = 7.5
Answer: 7.5

What is the contrapositive of "If our plane is not late, then we make our connecting flight.
Answer:
If we make our connecting flight then our plane is not late.
Step-by-step explanation:
The contrapositive occurs when the conclusion and the hypothesis change places. Let the hypothesis be represented by "p" and the conclusion be represented by "q".
hypothesis (p) [ conclusion (q)]
Now in the given statement: If (our plane is not late), then [we make our connecting flight].
statement If p then q
contrapositive If q then p
The required contrapositive statement is: "If we do not make our connecting flight, then our plane is late."
The contrapositive of the statement "If our plane is not late, then we make our connecting flight" is formed by negating the hypothesis (antecedent) and the conclusion (consequent) and then switching their positions. The contrapositive is logically equivalent to the original statement. Here's the contrapositive:
Original Statement: If our plane is not late, then we make our connecting flight.
Contrapositive: If we do not make our connecting flight, then our plane is late.
In the contrapositive, we negate the "our plane is not late" to "our plane is late" and negate "we make our connecting flight" to "we do not make our connecting flight." Then we switch their positions.

Sheila walks 3 miles in 9/10 of an hour. How fast does she walk per hour?
Answer:
1 hours = 60 min
60 x 9/10 = 54 min
3 divided by 54 = 1/18
so she walks 1/18 miles per hour.
Im not sure though. It might be 3 divided by 9/10 = 3 1/3. I’m not that confident in my answer. But it is definitely one of them, either 1/18 or 3 1/3.
