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

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]

Answer:

A. 5y + 4z

Step-by-step explanation:

the coefficient is the number placed after the variable

so 5y in A part. because 5 is written with Y which is a variable

===============================================

Explanation:

For these questions, we'll use the inscribed angle theorem. This says that the inscribed angle is half the measure of the arc it cuts off. An inscribed angle is one where the vertex of the angle lies on the circle, as problem 1 indicates.

For problem 1, the arc measure is 80 degrees, so half that is 40. This is the measure of the unknown inscribed angle.

Problem 2 will have us work in reverse to double the inscribed angle 42 to get 84.

-------------------

For problem 3, we need to determine angle DEP. But first, we'll need Thales Theorem which is a special case of the inscribed angle theorem. This theorem states that if you have a semicircle, then any inscribed angle will always be 90 degrees. This is a handy way to form 90 degree angles if all you have is a compass and straightedge.

This all means that angle DEF is a right angle and 90 degrees.

So,

(angle DEP) + (angle PEF) = angle DEF

(angle DEP) + (35) = 90

angle DEP = 90 - 35

angle DEP = 55

The inscribed angle DEP cuts off the arc we want to find. Using the inscribed angle theorem, we double 55 to get 110 which is the measure of minor arc FD.

Answer:

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)

Answer:

x = 34 degrees

Step-by-step explanation:

there are many rules when it comes to parallel lines but this is called corresponding angles which means if we know these two are parallel lines then x and 34 will be the same therefore x will equal 34

Answer:

150 pizzas

Step-by-step explanation

36 pizzas are equivalent to 24% so i divided both sides by 4 which gave me 9 pizzas  for 6% . But 6 cannot fully fit into 100 so it will have to be a decimal i did 100 divided by 6 so i would know what i would have to divide both sides by which gave me  50/3 which was 16.66666667 which when i times by 9 by it gave me 150 pizzas

Step-by-step explanation:

A rate is a special ratio in which the two terms are in different units. For example, if a 12-ounce can of corn costs 69¢, the rate is 69¢ for 12 ounces. When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates.

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.

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:

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

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).
