Answer:

x = 6

Step-by-step explanation:

using the cosine ratio in the right triangle and the exact value

cos60° = [tex]\frac{1}{2}[/tex] , then

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{12}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2x = 12 ( divide both sides by 2 )

x = 6

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.

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:

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.

Given :

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]

[tex]\qquad { \dashrightarrow{ \sf{ 10x \: cm= 10 \times 5 \: cm = \bf \: 50 \: cm }}}[/tex]

Step-by-step explanation:

Given:-

Ratio of sides of triangle is 5:8:10 , with perimeter of 115cm.

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

There are 4 positions in the string that each have 25 choices (any letter in the English alphabet except A) and the other positions are filled with A, so there are 25⁴ possible strings containing exactly 7 A's.

Overall, there are 26¹¹ possible strings of length 11.

Then the probability of randomly generating a string containing exactly 7 A's is

25⁴ / 26¹¹ ≈ 0.000000000106427

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:

The measure of one part of a rectangle divided into 4 parts is 1/4

If 1 whole is divided into 4 equal parts

= 1/4

So, if the perimeter of the rectangle is 60cm

1 part of 4 = 1/4 × 60cm

= 60/4

= 15 cm

Therefore, the measure of one part of a rectangle divided into 4 parts is 1/4
