Answer:

  x° = arcsin(15.5/26.9×sin(73°))

Step-by-step explanation:

The law of sines tells you the sine of an angle is proportional to the length of the opposite side:

  sin(x°)/15.5 = sin(73°)/26.9

  sin(x°) = (15.5/26.9)sin(73°) . . . . . multiply by 15.5

Using the inverse function, we can find x.

  x° = arcsin((15.5/26.9)sin(73°))

Step-by-step explanation:

Because we know Jordan already has $60, and he makes $6 per week, allwe have to do is multiply 6 times the number of weeks he is saving, which is also 6. That comes out to 36, so he saves $36 in 6 weeks, but we are tyring to find the total amount, so we add 36 and 60 to get 96.

Therefore, Jordan saves $96 after 6 weeks.

The next part of the questions asks for an expression. In the expression, w represents the amount of weeks. So, since he already had the $60, the expression would be:

60 + 6w

Answer:

1/4

Step-by-step explanation:

For a die,

the number of possible results is 6

The prime numbers are 2,3,5

the probability of getting a prime number is thus; 3/6 = 1/2

Tossing a coin, the probability of getting a head is also 1/2

So the probability of getting both on a single toss will be;

1/2 * 1/2 = 1/4

According to the question,

The number of possible results,

Prime numbers,

Now,

The probability of getting a prime number will be:

= [tex]\frac{3}{6}[/tex]

= [tex]\frac{1}{2}[/tex]

then, by tossing the coin head's probability is "[tex]\frac{1}{2}[/tex]".

hence,

Getting both on single toss will be:

= [tex]\frac{1}{2}\times \frac{1}{2}[/tex]

= [tex]\frac{1}{4}[/tex]

Thus the above answer is right.

Answer:

(1) 1/8

(2) 1/12

(3) 1/16

(4) 1/20

Step-by-step explanation:

We need to find multiple divisions, it says  1/4 divided by 2 then go back to 1/4 and divide it again but by 3 then go back to it again and divide it by 4 then go back to 1/4 and divide it by 5.

We will take one by one

(1) 1/4 divides by 2 will be  = 1/8

(2) 1/4 divided by 3 = 1/12

(3) 1/4 divided by 4 = 1/16

(4) 1/4 divided by 5 =1/20

These results are obtained by dividing the given parts, as the given Numerator is in fraction so whatever will be divided from the fractional numerator will get multiplied with the denominator.

Given:

The expression is

[tex]2b+5+1b=3b+5[/tex]

To find:

Whether the two expression in the equation are equal or equivalent.

Solution:

If two expression are exactly the same, then they are equal and if the two expressions are different but the after simplification both are same, then they are called equivalent expressions.

We have,

[tex]2b+5+1b=3b+5[/tex]

Taking LHS, we get

[tex]LHS=2b+5+1b[/tex]

On combining liker terms, we get

[tex]LHS=(2b+1b)+5[/tex]

[tex]LHS=3b+5[/tex]

[tex]LHS=RHS[/tex]

In the given equation both expression are different but after simplification LHS = RHS, therefore the expression are equivalent not equal.

Answer:

6 bowls of ramen eaten by you & your friend

Step-by-step explanation:

The question appears pretty choppy for me. I'll answer what I think you're asking and update in the comments if needed.

Imagine that you and a friend go to a local ramen shop for dinner at this restaurant, each regular bowl of ramen is $7.25. Drinks are $1.50 each. How many regular bowls of ramen did you and your friend eat if you ordered 2 drinks each and your total was $49.50?

a. Write an equation to represent the situation using x to represent the # of bowls you and your friend ate.

4($1.50) + $7.25x = $49.50

6 + 7.25x = 49.50

subtract 6 from both sides

7.25x = 43.50

divide both sides by 7.25

x = 6

Checking the math:

4(1.5) + 6(7.25) = 6 + 43.50 = 49.50

4 drinks, 6 bowls of ramen for $49.50

Answer:

w = -z(-w) + 3(-w)

Step-by-step explanation:

z = w + 3 | Given

-w + z = 3 | Subtract w from both sides.

-w = -z + 3 | Subtract z from both sides

w = -z(-w) + 3(-w) | Multiply -w on both sides.

Median = 6, Lower quartile = 5; Upper quartile = 7; Interquartile range =2

The numbers that divide a piece of data into four equal portions are known as quartiles. A data set is divided in half by its median. The lower quartile (LQ) is the median value for the lowest half of a set of data. The upper quartile (UQ) is the median value for the higher half of a set of data.

Given data is:

7, 5, 3, 8, 6.

in ascending order the data is:

3, 5, 6, 7,8.

Hence, the median is = middle number from the data =   6.

The Lower quartile is =middle number from the lower part of the data = 5

The Upper quartile is = middle number from the data =7.

hence, the Interquartile range  is = upper quartile - lower quartile

= 7 - 5

= 2.

Answer:

sqrt(x)=x^1/2

Step-by-step explanation:

The root of a number is the same as writing that number to 1 over the root. In a square root, it is what number multiplied by itself (x*x), as you can see there are two, so it is that number to the 1/2 power. another example is something to the seventh power. that is calculating what number multiplied by itself 7 times would equal the nmber you are taking the root of. (x*x*x*x*x*x*x) so this would be a number to the 1/7 power.
