Answer:

20/3

Step-by-step explanation:

To figure this out, you would multiply 5 by the reciprocal of the fraction. The reciprocal is the fraction flipped around. 3/4 flipped around would be 4/3.

5*4/3=20/3

Answer:

x = 7

y = 10

Step-by-step explanation:

<K and <NLK are marked as being equal.

That means that KN and LN are equal.

So LN = 6

y - 4 = 6

y = 4 + 6 = 10

For the same reason LN = LM

That means that x + 3 = 10

x = 10 - 3

x = 7

Answer:

D. a║b, because if two lines are perpendicular to the same line, then they are parallel to each other.

Step-by-step explanation:

This is more of a rule than anything else, but to prove this, you can think of c as the transversal. The 4 angles at the intersection of line a and line c are 90 degrees, and so are the 4 angles at the intersection of line b and line c. Using the converses of the Corresponding Angles Theorem, Same Side Interior Angles Theorem, Alternate Interior Angles Theorem, etc.., you can prove that a and b are parallel.

Answer:

Less than 25%

Step-by-step explanation:

1. Find the difference of the two numbers: 1,207 - 957 = 250

decrease = original number - new number

2. Then, divide the decrease by the original number

250/1,207 = 0.207

3. Multiply the answer by 100 to get the percentage

0.207 x 100 = 20.7%

Therefore, the number of people fell by 20.7%

Hence, the answer is less than 25%

Answer:

Carbon-14 will take 19,035 years to decay to 10 percent.

Step-by-step explanation:

Exponential Decay Function

A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay.

An exponential decay can be described by the following formula:

[tex]N(t)=N_{0}e^{-\lambda t}[/tex]

Where:

No  = The quantity of the substance that will decay.

N(t) = The quantity that still remains and has not yet decayed after a time t

[tex]\lambda[/tex]     = The decay constant.

One important parameter related to radioactive decay is the half-life:

[tex]\displaystyle t_{1/2}=\frac {\ln(2)}{\lambda }[/tex]

If we know the value of the half-life, we can calculate the decay constant:

[tex]\displaystyle \lambda=\frac {\ln(2)}{ t_{1/2}}[/tex]

Carbon-14 has a half-life of 5,730 years, thus:

[tex]\displaystyle \lambda=\frac {\ln(2)}{ 5,730}[/tex]

[tex]\lambda=0.00012097[/tex]

The equation of the remaining quantity of Carbon-14 is:

[tex]N(t)=N_{0}e^{-0.00012097\cdot t}[/tex]

We need to calculate the time required for the original amout to reach 10%, thus N(t)=0.10No

[tex]0.10N_o=N_{0}e^{-0.00012097\cdot t}[/tex]

Simplifying:

[tex]0.10=e^{-0.00012097\cdot t}[/tex]

Taking logarithms:

[tex]ln 0.10=-0.00012097\cdot t[/tex]

Solving for t:

[tex]\displaystyle t=\frac{log 0.10}{-0.00012097}[/tex]

[tex]t\approx 19,035\ years[/tex]

Carbon-14 will take 19,035 years to decay to 10 percent.

Answer:

D 16 cupcakes and 40 cookies

Step-by-step explanation:

I wrote an equation to solve for this

2.5x + x = 56

x represents cupcakes

3.5x = 56

x = 16

16 represents cupcakes.

16*2.5 = 40 (cookies)

Answer: x = 5.2425

Graphing It Is undefined which means there  is no solution

Step-by-step explanation:

Answer:

Neither

Step-by-step explanation:

For two lines to be parallel, they must have the same slope. 2 and -2 are not the same. For lines to be perpendicular, their slopes must be negative reciprocals (ex 5 and -1/5) The slopes of these lines are not the same or negative reciprocals, so they are not parallel or perpendicular.

Answer:

Your answer is -25

Step-by-step explanation:

First, you figure out what to do for the equation.

In this case we you would subtract because it says "what is the difference" which means to subtract.

So -55 subtracted by -80 = -25

Answer:

A

Step-by-step explanation:

Kayla spends 6 a day and has a total of 30 dollars, c is the amount left over so this would make the equation c=30-6d

The correct statement will be;

⇒ c = 30 - 6d

Where, 'c' is left amount and 'd' is number of days.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Kayla has $30 to spend on yogurt.

And, She spent a total of $6 each day on yogurt.

Now,

Let 'c' is left amount and 'd' is number of days.

And, She spent a total of $6 each day on yogurt.

So, We can formulate;

⇒ c = 30 - 6d

Where, 'c' is left amount and 'd' is number of days.

Thus, The correct statement will be;

⇒ c = 30 - 6d

Where, 'c' is left amount and 'd' is number of days.

Answer:

C

Step-by-step explanation:

To find the area of a circle, take its radius (3) and square it. In this case, 3 times 3 = 9. Then, you multiply the answer by pi, which rounds to 3.14, but is more like 3.14159265......etc, etc. There is a rhyme for that: May I have a large container of coffee beans? Where the length of each word is a number of pi. Anyway, most people would write 9pi, but this is asking for the exact answer, so you can do 3.14 times 9, which equals roughly 28.27. Hope this helped!        

Answer:

For me the answer was (f+g)(x)=4x^3+x^2+5x+2

Step-by-step explanation:

A function assigns the values. The value of the (f-g)(x) is 4x³ + x² +2 is 4x³ + x² + 5x + 2.

A function assigns the value of each element of one set to the other specific element of another set.

Given that f(x)=4x²+5x-3 and g(x)=4x³-3x²+5, therefore, the value of the (f-g)(x) can be written as,

(f-g)(x) = f(x) - g(x)

          = 4x² + 5x - 3 + 4x³ - 3x² + 5

          = 4x³ + 4x² - 3x² + 5x + 5 - 3

          = 4x³ + x² +2

Hence, The value of the (f-g)(x) is 4x³ + x² +2 is 4x³ + x² + 5x + 2.

Answer:

322 1/2 miles

Step-by-step explanation:

Recall how s = d/t ; speed = distance/time.

To effectively solve for distance traveled, rearrange the formula so that distance is on the left-hand side by multiplying speed, and time.

speed × time = distance/time × time

speed × time = distance

distance = speed × time ; d = st.

Now to find the total distance traveled, individually multiply the rate of speed with the time. Time will cancel, and we will get the total mileage.

Given an average speed of 60 mph at a certain time for 4.5 hours, and another average speed of 35 mph at another time of 1.5. Calculate the distance individually, and then add both distances together. Distance 1 = 60 mph × 4.5 h = 60 miles / h × 4.5h = 60 miles × 4.5 = 270 miles.

Distance 2 = 35mph × 1.5h = 35 miles / h × 1.5h = 35 miles × 1.5 = 52 1/2 miles.

Distance 1 + Distance 2 = Total distance.

270 miles + 52 1/2 miles = 322 1/2 miles.
