What is the slope of a line perpendicular to the line whose equation is 15x+18y=270. Fully simplify your answer.

Answer:

a=1

Step-by-step explanation:

2/3a + 5/6a - 1/6 = 0

-2/3a + 5/6a = 1/6

5/6a - 2/3a = 1/6

Lowest common multiple of 3 and 6 =6

(5/6-4/6)a =1/6

1/6a = 1/6

a=1/6 / 1/6

a=1

Answer:

D. 60cm²

Step-by-step explanation:

First, notice how the partially shaded squares fit perfectly into one another (the squares are perfectly cut from corner to corner). Once you match these squares to one another, you can then figure out that they add up to three full squares.

Secondly, measure how many squares there will be in the diagram after adding up the partial squares (resulting in a total of 15).

Finally, calculate the area of one of the squares (2cm x 2cm), which results in 4cm². As you have 15 total squares, multiply 4cm² by that to get the final answer of 60cm².

Answer:

2n

Step-by-step explanation:

You pack sandwiches for a mountain hike with your friends.

Each [ meaning 1]  sandwich takes 2 slices of bread.

If each hiker eats one sandwich, and there are 'n' hikers

Thus, to find the number of breads used for 'n' hikers, we multiplied 2 by n

Hence, the expression will be 2n

Answer: r = 16

Step-by-step explanation:

We know that triangle ABC is a right triangle.

Therefore, we can use the pythagorean theorem to solve for r.

r^2 + 30^2 = (r+18)^2

r^2 + 900 = r^2 + 36r + 324

Combine like terms:

36r = 576

Divide both sides by 36:

r = 16

Answer:

5: 0 successes

6: 5 successes

7: 8 successes

8: 6 successes

9: 6 successes

10: 1 success

We need to use her results to estimate the probability that she succeeds at fewer than 7 free-throws in a sample of 10 free-throws.

First, find out how many successes were less than 7 (out of 25), which is 5.

now, we divide 5 by 25 (5/25, formula being number/total attempts) and simplify into a decimal, which comes out to 0.2

Probability w/ Venn Diagrams

Step-by-step explanation:

Disclaimer: The question was incomplete. The complete question can be seen in the image attached.

The estimated probability of Maria succeeding at fewer than 7 free throws in a sample of 10 free throws is 1/5 or 0.2.

The probability of an event is the fractional value showing how likely is that event to occur. It is determined by the formula =

The number of outcomes favorable to the event/the total number of outcomes.

The results from the 25 samples showing the number of success in each trial of 10 throws are:

5 success: 0 outcomes

6 success: 5 outcomes

7 success: 8 outcomes

8 success: 6 outcomes

9 success: 5 outcomes

10 success: 1 outcome.

We are asked to estimate the probability that Maria succeeds at fewer than 7 throws in a sample of 10 free throws.

From the result of 25 samples of 10 free throws each, we see that Maria succeeds fewer than 7 times, that is, 5 and 6 times for 0 + 5 = 5 outcomes.

∴ The probability of Maria succeeding at fewer than 7 throws in a sample of 10 free throws = 5/25 (favorable outcomes/total outcomes)

= 1/5 or 0.2.

So, the estimated probability of Maria succeeding at fewer than 7 free throws in a sample of 10 free throws is 1/5 or 0.2.

To find a common ratio, you divide each term by the previous term.

So, let's do it for each sequence.

A.

6 / 2 = 3

10 / 6 = 1.6667

It is incorrect because we did not get 4.

B.

4 / 1 = 4

16 / 4 = 4

It is correct because we got 4.

C.

400 / 1600 = 1/4

100 / 400 = 1/4

It is incorrect. The common ratio is 1/4.

D.

8 / 2 = 4

32 / 8 = 4

It does have a common ratio of 4. It is correct.

E.

12 / 16 = 0.75

8 / 12 = 0.6667

It does not have a common ratio of 4.

F.

1/8 / 1/2 = 1/4

1/32 / 1/8 = 1/4

It does not have a common ratio of 4. It has a common ratio of 1/4.

The number of years it takes for the balance in your savings account to reach $5625.41 is 11 years

The formula for calculating compound interest is expressed as;

A =P(1+r)^t

Given the following

A =  $5625.41

P = $4000

r = 0.031

Substitute the given parameters into the formula to have:

$5625.41 = 4000(1.031)^t
1.4063525 = (1.031)^t
t = ln(1.4063525)/ln(1.031)

t = 0.34074/0.03052

t = 11 years

Hence the number of years it takes for the balance in your savings account to reach $5625.41 is 11 years

Answer:

False. Sin is not a linear function. Thus, two smaller sin funstions will not equal a larger.

Step-by-step explanation:

Intermediate Value Theorem: Suppose that  f(x)  is an arbitrary, continuous function on an interval  [a,b] . If there exists a value  L  between  f(a)  and  f(b) , then there exists a corresponding value  c∈(a,b) , such that  f(c)=L

f(x)=x3+4x−1

f(0)=−1f(1)=4

Since the function changes sign in the interval  (0,1) , hence there exists a  c∈(0,1)  such that  f(c)=0

To Find :

Solution :

Let us assume the sides be 5x cm, 8x cm and 10x cm.

We know,

[tex]\qquad{ \bold{ \pmb{Sum \: of \: all \: sides \: of \: the \: triangle = Perimeter_{(Triangle)}}}}[/tex]

So, Substituting the values :

[tex]\qquad { \dashrightarrow{ \sf{5x + 8x + 10x = 115}}}[/tex]

[tex]\qquad { \dashrightarrow{ \sf{23x= 115}}}[/tex]

[tex]\qquad { \dashrightarrow{ \sf{ \dfrac{23x}{23} = \dfrac{115}{23} }}}[/tex]

[tex]\qquad { \dashrightarrow{ \bf{ x = 5 }}}[/tex]

Therefore,

The length of the sides of the triangle are :

[tex]\qquad { \dashrightarrow{ \sf{ 5x \: cm= 5 \times 5 \: cm = \bf \: 25\: cm }}}[/tex]

[tex]\qquad { \dashrightarrow{ \sf{ 8x \: cm= 8 \times 5 \: cm = \bf \: 40 \: cm }}}[/tex]

To Find :-

Measurement of each side

Solution :-

let the each side be 5x , 8x , 10x respectively

we know that ,

perimeter of triangle = sum of all sides

putting the known values ,

115cm = 5x + 8x + 10x

115/23 = x

5 = x

putting the value of x we get ,

each side is 25cm , 40cm , 50cm
