After Friday's football game, Megan and her friends go out for ice cream. They share the Mega Mountain sundae and finish the whole thing! When they pay for the sundae, Megan evenly divides the total among 5 people. Each person pays $5.20. Which equation can you use to find the total cost c of the sundae?
Answer: c= $( 5 x 5.20)
Step-by-step explanation:
Given: Total people =5
Money paid by each person = $5.20
Total cost of the sundae = (Number of people ) x (Money paid by each person)
Total cost of sunday : c= 5 x ($5.20)
i.e.Total cost of sunday = $(5 x 5.20)
i.e.Total cost of sunday = $ 26
Hence, the required equation to represent the total cost (c) of the sundae:
c= $( 5 x 5.20)

How do the values of the 4s in 64.723 and 9.048 compare? Choose the best answer below to correctly complete the statement. The value of the 4 in 64.723 is 10 100 1000 times the value of the 4 in 9.048.
Answer:
100
Step-by-step explanation:
4 in 64.723 is a unit value. So it has a value of 1
4 in 64.723 has a value of 0.01
so the value of 4 in 64.723 is 100 times the value of the 4 in 9.048.

HELP What is the area of a circle with a radius of 13 feet? IT IS NOT 530.93 ft
Answer:
530.66
Step-by-step explanation:
to find the area you need to do pi times the radius square and to find the radius squared you just times it by its self so 13 times 13 which is 169 and pi is 3.14
so now you just do 3.14x169=530.66
the half-life of chromium-51 is 38 days. If the sample contained 510 grams. How much would remain after 1 year?
Answer:
About 0.6548 grams will be remaining.
Step-by-step explanation:
We can write an exponential function to model the situation. The standard exponential function is:
[tex]f(t)=a(r)^t[/tex]
The original sample contained 510 grams. So, a = 510.
Each half-life, the amount decreases by half. So, r = 1/2.
For t, since one half-life occurs every 38 days, we can substitute t/38 for t, where t is the time in days.
Therefore, our function is:
[tex]\displaystyle f(t)=510\Big(\frac{1}{2}\Big)^{t/38}[/tex]
One year has 365 days.
Therefore, the amount remaining after one year will be:
[tex]\displaystyle f(365)=510\Big(\frac{1}{2}\Big)^{365/38}\approx0.6548[/tex]
About 0.6548 grams will be remaining.
Alternatively, we can use the standard exponential growth/decay function modeled by:
[tex]f(t)=Ce^{kt}[/tex]
The starting sample is 510. So, C = 510.
After one half-life (38 days), the remaining amount will be 255. Therefore:
[tex]255=510e^{38k}[/tex]
Solving for k:
[tex]\displaystyle \frac{1}{2}=e^{38k}\Rightarrow k=\frac{1}{38}\ln\Big(\frac{1}{2}\Big)[/tex]
Thus, our function is:
[tex]f(t)=510e^{t\ln(.5)/38}[/tex]
Then after one year or 365 days, the amount remaining will be about:
[tex]f(365)=510e^{365\ln(.5)/38}\approx 0.6548[/tex]

Y=? Need help ASAP very much appreciated
Answer:
8
Step-by-step explanation:
I'm guessing the answer is 8 because when y is -8, x is 4. So, my thought in mind is when x is negative, y is positive. It also says, "If the value of "y" varies directly with "x". So, this means the answer is 8. You're very much welcome! Also, I'm sorry if this is incorrect. I tried my best with this question but I'm pretty sure the answer is 8! Have a great day sunshine!! :)
Answer: y = 8

Find the area of this composite figure.
Answer: ≈ 551.71 ft²
All work is shown in the picture.
Answer:
551,7
see in the picture, this composite figure is made up of a rectangle and 2 halves of a circle
=> the area of this composite figure = the area of a rectangle + the area of a circle
+) the area of the rectangle = 15.25 = 375
+) the area of the circle = (15/2)².pi = 56,25pi
=> the area of this figure = 375 + 56,25pi = 551,7
how do I get the area of a circle?
Answer:
The area of a circle is pi times the radius squared (A = π r²).

Answer:
owes $12.50
Step-by-step explanation:
2.5*5
=12.5
Answer:
-12.5
Step-by-step explanation:
If you do 2.50*5 (because Ms. Ortiz borrows $2.50 every day for 5 days) it equals 12.5, and since it's how much she owes, you have to make it negative, so it's -12.50 or she owes $12.50 (the first one if you are supposed to have the answer be negative, the second one if you have to have it in money form).

The Richter scale magnitude reading m is given by m=log10x , where x represents the amplitude of the seismic wave causing ground motion. Determine the reading of an earthquake that is 10 times less intense than an earthquake that measures 4.5 on the Richter scale.
Answer: The reading would be 5.5 on the Richter scale.
Step-by-step explanation:
The intensity of an earthquake that measures 4.5 on the Ritcher scale can be found by solving:
4.5 = log₁₀(x)
for x.
remember that:
logₐ(x) = ln(x)/ln(a)
Then we can rewrite our equation as:
4.5 = ln(x)/ln(10)
4.5*ln(10) = ln(x)
we also know that:
ln(exp(x)) = exp(ln(x)) = x
Then we can apply the exponential equation to both sides to get:
exp( 4.5*ln(10)) = exp( ln(x) ) = x
exp( 4.5*ln(10)) = x
x = 31,622.8
Now, if we have an intensity 10 times larger than this, we will have:
x = 10*31,622.8 = 316,228
The reading on the Richter scale will be:
m = Log₁₀(316,228) = 5.5

Answer:
She will have $2,200
Step-by-step explanation:
Im assuming shes getting paid interest every month.
10% of 1,000 is 100
So, when you mulitiply 100 times 12
You get 1,200
You add that to the original amount of savings
And she ends up with $2,200
If you don’t know the answer pls don’t reply thank you
Answer:
Is B
Step-by-step explanation:
It's B because you use cups with the tablespoons to find the answer. 2 is cups, and it's on the numerator, and 1.5 is cups. It would have to be a numerator since you would only use denominators to plug in the value of tablespoons in the equation. v would be the denominator with 1.5 as the numerator since we are trying to find v with 1.5, so 1.5 has to be in the same fraction.
Hope this helps!
