Answer:

4.99

Step-by-step explanation:

i cant remember how i got 4.99 but can show u how to check

= 55 + 4.99 = 59.99

59.99 divide 3 = 19.99666667

= 19.99666667 divide 4 (working in reverse as it says 4 times the orig no.)

= 4.99 (was rounded)

Answer:

Jaimy's fifth term equals Monica third term of 36.

Step-by-step explanation:

Monica:

Multiply by 3 and starts at 4.

4*3 = 12

12*3 = 36

36*3 = 108

...

So: {3,12,36,108,...}

Jaimy:

Adds 6 and starts at 12. So

12 + 6 = 18

18 + 6 = 24

24 + 6 = 30

30 + 6 = 36

...

So: {12,18,24,30,36,...}

So Jaimy's fifth term equals Monica third term of 36.

Step-by-step explanation:

Answer:

28 cm²

Step-by-step explanation:

We are asked to find the surface area of the given square pyramid. To do this we can find the sum of the areas of each of the faces of the square pyramid, including the base.

Since this is a square pyramid, we know that each of the triangle faces of the pyramid have the same area, being the congruent triangles, and that there are 4 triangle faces.

Since this is a square pyramid, we know that the base of the pyramid is a square.

So to find the surface area we can multiply the area of one of the triangle faces by 4 and add it to the area of the square base. In other words:

(4 × area of triangle face) + area of square base = surface area

Lets start with finding the area of the square base. we are given that the side length of the base is 2 cm. Remember, the area of a square is:

s × s

or

s²

where s is the side length of the square.

Lets plug in 2 for s:

2 × 2 = 4

or

2² = 4

So the area of the square base is 4 cm².

Now lets find the area of the triangle side.

Remember, the area of a triangle is:

[tex]\frac{1}{2}(b*h)[/tex]

where b is the length of the base (not to be confused with the base of the pyramid) and h is the height.

We are given that the height of the pyramid is 6 cm and the base is 2 cm. Lets plug in 6 for h and 2 for b:

[tex]\frac{1}{2}(6*2)=\frac{1}{2}*12=6[/tex]

So the area of a triangle side of the pyramid is 6 cm².

Now lets find the surface area. To do this we can multiply the area of a triangle side of the pyramid by 4 and add the area of the square base. Remember, the area of the square base was 4 cm² and the area of the triangle side was 6 cm².

(4 × 6) + 4 = 24 + 4 = 28

So the surface area would be 28 cm²

I hope this helps. Let me know if you have any questions. Happy studying.

Answer:

your answer I think would be 20 miles

Answer:

2 minutes 10 seconds = 130 seconds

Step-by-step explanation:

Given that,

LHS = 2 minutes 10 seconds

RHS = 130 seconds

Solving LHS first,

We know that,

1 minute = 60 seconds

2 minute = 120 seconds

2 minutes 10 seconds = 120s + 10 s

= 130 seconds

It means,

LHS = RHS

So,

2 minutes 10 seconds = 130 seconds

Answer:

..........

Step-by-step explanation:

1 = 1 × 2 = 2

3. 3×2. 6

Answer:

1a ) N_6 = 50 mg

1b) N_3 = 70.7 mg

1c) N_1 = 89.1 mg

2) f(t) = 100e^(-0.1155t)

Step-by-step explanation:

Formula to get amount remaining is;

N_t = N_o × ½^(t/t_½)

We are given;

N_o = 100 mg

t_½ = 6 years

We have; N_t = 100(½^(t/6))

Thus;

1a) amount left after 6 years is;

N_6 = 100 × ½^(6/6)

N_6 = 50 mg

1b) amount left after 3 years is;

N_3 = 100 × ½^(3/6)

N_3 = 70.7 mg

1c) amount left after 1 year is;

N_1 = 100 × ½^(1/6)

N_1 = 89.1 mg

2) to find the function to model the amount left after t years, let's use the formula;

f(t) = f_o × e^(-rt)

Where r is decay constant

Thus;

f(t) = 100e^(-rt)

We recall that N_t = 100(½^(t/6))

Thus;

100(½^(t/6)) = 100e^(-rt)

Divide both sides by 100 to get;

(½^(t/6)) = e^(-rt)

In (½^(t/6)) = In e^(-rt)

Using power rule, we have;

(t/6) In ½ = -rt In e

-0.6931t/6 = - rt (because In e = 1)

t will cancel out to give;

r = 0.6931/6

r = 0.1155

Thus;

f(t) = 100e^(-0.1155t)

Answer:

4 2/3 ÷ 3 1/3= 1 2/5

Step-by-step explanation:

First, you turn the mixed terms into an improper fraction like this

4 2/3 → 14/3 because when you multiply 4 times 3 equaling 12 then having 2 then adding that you get 14/3.

3 1/3 → 10/3 because when you multiply 3*3=9 then having 1 and adding that you get 10/3.

Then, you do KCF which stands for Keep Change Flip so for this you would do: 14/3 ÷ 10/3 → 14/3 × 3/10

14 × 3 = 42 and 3 × 10= 30

Now being 42/30 this is considered an improper fraction in which you have to transform it into a mixed number like this:

(For this you need to find the greatest common factor)

42/30 →  42 and 30 greatest common factor is 6 because they are divisible and factor of 6.

Now you divide both the denominator and the numerator y 6 like this:

42 ÷ 6= 7

30 ÷ 6= 5

Now we have 7/5, this is still an improper number so we see how many times 7 can go to 5 which is once. So we have 1 as whole number, now we put the reminder as the numenator of the mix fraction keeping 5 as being the denominator.

Overall, We have our answer 1 2/5

I hope this helps :D  

Answer: The center is (-5,2)

The radius is 5

Step-by-step explanation:

Equation of a circle is:

(x-h)^2+(y-k)^2=r^2

(x+5)^2+(y-2)^2=5^2

Comparing both equations we get :

The center (-5,2)

The radius is 5

Answer:  66.

explanation: Ok so right triangle: 1 right angle or 90° and 2 acute angles (Less than 90°). We know that one of the angles are equal to 24° and the right angle is equal to 90° degrees. Now what? We add those 2 values together. 90 + 24 = 114. In the background, a triangle is equal to 180°. So now that we have our 2 core values together, we subtract. The reason why is because this is a missing value type equation. In these types, (usually indicated by the word find) we can subtract 2 values. Our 2 values is 114 and 180. When we subtract both, we get 66.
