What is the area of the triangle?

Answer:

70 sec (1 min 10 sec)

Step-by-step explanation:divide 28 by 2 and get 14 and multiply that by 5 to get 70 sec

Answer:

14 cm per day

Step-by-step explanation:

To find the water level increase rate in cm per day, divide 84 by 6, since it increased by 84 cm in 6 days:

84/6

= 14

So, the water level increase rate in 14 cm per day

Answer:

B.) X less than or equal to 16.5

Step-by-step explanation:

If you take his limit, 40 and subtract the 7 dollars you will get 33. Then, divide that by two because he will need two tickets and you will get 16.5. It can't be greater than 16.5 because he will go over his budget.

Answer:

x ≤ 16.5

Step-by-step explanation:

40 ≤ 2t + 7 Subtract 7 from both sides.

40 - 7 ≤ 2t + 7 - 7

33 ≤ 2t Divide both sides by 2.

[tex]\frac{33}{2}[/tex] ≤ [tex]\frac{2t}{2}[/tex]

16.5 ≤ t or t ≥ 16.5

Work Shown:

Use the pythagorean theorem

a^2+b^2 = c^2

21^2 + 20^2 = c^2

441 + 400 = c^2

841 = c^2

c^2 = 841

c = sqrt(841)

c = 29

Answer:

4s + 6a + 5c = 1,660

s = 2a

s + a + c = 353

Step-by-step explanation:

s = # of student tickets bought

a = # of adult tickets bought

c = # of senior citizen tickets bought

Answer/Step-by-step Explanation:

Given:

a = no. of DVDs

b = no. of CDs

Total cost ($) for DVDs and CDs = [tex] 2.5a + 2b [/tex]

a. The cost for 1 DVD = 2.5(a) = 2.5(1) = $2.5

The cost for 1 CD = 2(b) = 2(1) = $2

b. Total cost for 4 DVDs and 4 CDs:

Substitute a = 4, and b = 4 into the equation.

[tex] 2.5(4) + 2(4) [/tex]

[tex] 10 + 8 = 18 [/tex]

Total cost for 4 DVDs and 4 CDs = $18

c. To find out if $20 would be enough to buy 6 DVDs and 3 CDs, substitute a = 6, and b = 3 into the equation. Solve for the total cost to see if it equals $20 or is less than $20. If it's greater than $20, then it won't be enough.

[tex] 2.5(6) + 2(3) [/tex]

[tex] 15 + 6 = 21 [/tex]

6 DVDs and 3 CDs cost more than $20, therefore, $20 is not enough.

Answer:

15,300

Step-by-step explanation:

multiply the estimated total number of births (255)

times 60 because there is 60 minutes in an hour

255*60= 15,300

Answer:

15,300

Step-by-step explanation:

1 hour: 60 minutes

60 x 255 = 15,300

Answer: f(x) = -3 if -4 ≤ x ≤ -1

Answer:

-27x+63

Step-by-step explanation:

you do -9 times 3x then -9 times -7, two negatives creates a positive, and so 9 times 7 equals 63

hope this helps :^)

-9(3x-7)

Multiply each term in the parentheses by -9

-9×3x-9×(-7)

Calculate the product

-27x-9×(-7)

now we do the same thing only different way ok

-9×3x

Multiplying a negative and a positive equals a negative : (-)x(+)=(-)

-(9×3)x

Multiply the numbers

-27x

-9×3x-9×(-7)

Multiply the numbers

-27x+63

Now we do the same thing only different way ok

-9×(-7)

Multiply two negatives equals a positive: (-)×(-)=(+)

9 × 7

multiply the numbers

63

Solution: -23x+63

Answer: 15, and 44 are integers.

Step-by-step explanation: For 15 to be an integer, 15 has to be a whole number. Furthermore, for 15 to be an integer, you should be able to write 15 without a fractional or decimal component. 15 is a whole number that can be written without a fractional component, thus 15 is an integer, as well as 44.

Answer:

6y

Answer:

[tex]T_n = 7.143(0.7^n)[/tex]

Step-by-step explanation:

If a ball bounces to a height of 5feet, the initial drop = 5feet

If the ball rebounds to 70% of its previous height after each bounce, the next height after rebouncing will be expressed as;

= 70% of 5

= 70/100 * 5

= 0.7*5

= 3.5 feet

The next height will be 0.7*3.75 = 2.45 and so on

The  heights wil form a sequence as thus;

5, 3.5, 2.45...

This sequence forms a geometric progression.

To get the function that could be used to model the nth term in the sequence of heights of the ball after the initial drop, w will find the nth term of the sequence

[tex]T_n = ar^{n-1}[/tex]

a is the first term of the sequence

n is the number of terms

r is the common ratio

From the sequence:

a = 5

[tex]r = \frac{3.5}{5} = \frac{2.75}{3.5} = 0.7[/tex]

Substitute the given values into the formula

[tex]T_n = 5(0.7)^{n-1}\\T_n = 5(\frac{0.7^n}{0.7^1} )\\T_n = \frac{5}{0.7}\times 0.7^n \\T_n = 7.143(0.7^n)[/tex]

The nth tern=m required is [tex]T_n = 7.143(0.7^n)[/tex]

hi there! here's my answer for you...

i do not think there is an answer since the equation you have given is not a conic section. therefore, there is no vertex form, axis of symmetry, or vertex.

hope this helped. have a good one!

Answer: B

Step-by-step explanation:

We have to find the amount that Maya painted IN ALL, which means we must add 3/4 and 1/8. First, look for the answer choice that has 1/8 as a number (B and A). However, none of the answer choices have 3/4 as an answer, so we must convert it into an equivalent fraction, 6/8. You get 6/8 by multiplying both the numerator and denominator by 2. Therefore the answer is B.

The amount of work done if a person carries 5n of candy 25m when trick or treating is 125.

In order to determine the amount of  work done we are going to multiply the force by the distance.

Using this formula

Work done = Force  x Distance

Where:

Force = 5n

Distance  = 25m

Let plug in the formula

Work done = 5 x 25

Work done= 125

Inconclusion the amount of work done if a person carries 5n of candy 25m when trick or treating is 125.

The work done  if a person carries 5n of candy 25m when trick or treating is; 125 J.

We are given;

Force carried; F = 5n

Distance covered; d = 25 m

Now, the formula for work done is given as;

Work done = Force × Distance

Thus;

Work done = 5 × 25

Work done = 125 N.m

In conclusion, the work done  if a person carries 5n of candy 25m when trick or treating is 125 N.m or 125 J.
