18. When an article is sold for $100 a profit of 25% is made on the cost price. What is the cost price?

Answer:

This illustrates a right triangle.

Given:

a(height) = 2457 ft.

∠A = 22°23' ; which is the elevation and reflects the a(height)

Find:

b(base)

Solution:

Using the law of cosine, specifically tan∠ = opposite side÷adjacent side

By analysis, tan∠A = a÷b

Since we are finding b, the formula will be derived into:

b = a÷tan∠A

Find b(base):

b = 2457 ft. ÷ tan22°23' ; substituting the numbers

b ≈ 5,966.05 ft. ; Final Answer

Step-by-step explanation:

1/8

Answer:

1/8 or 0.125 or 12.5%

Step-by-step explanation: You can multiply both denominator and numerator of 3/4 to become 6/8. Then you subtract it from 7/8 which leaves you with 1/8.

Answer:

-2.8

Step-by-step explanation:

Given that:

Mean, μ = 78

Standard deviation, σ = 5

Omar's score, x = 64

The Zscore of Omar's score :

Zscore = (x - μ) ÷ σ

Zscore = (64 - 78) / 5

Zscore = - 14 / 5

Zscore = - 2.8

Hence, Omar's exam score is - 2.8

Answer:

-2.8 is correct

Step-by-step explanation:

x/12=tan53

x=12tan53

x=15.9

Answer:

Tangent is opposite over hypotenuse, so tan(53)=x/12. Then you can solve easily.

Answer:

um, I am confused on the answer options, but 3(p+5) is equivalent

Step-by-step explanation:

3p+15 is the same a 3(p+5) because in 3(p+5) we have to use the distribution property

So, it is 3p +15 here's a picture to explain it better

(3(p+45) would be too big of a number as you also use the distribution property and it would be 3p+135)

Answer:

He missed 3 questions (which is a score of 22/25 that equals 88%)

Step-by-step explanation:

This is just what I've taught to judge this by "eye level" how to solve questions like these. In this case, since it's a 25 question test, if you divide 25/100 that means each question was 4 points.

So if 20/25 is 80% and 25/25 is 100%, so the answer is between that range.

Hope it helps.

Answer:

$40

Step-by-step explanation:

Tax is a sum levied by the government or an agency of the government on goods and services. taxes increases the price of products

Let p = price of a vest

from the question, this equation can be formed :

0.035 x p = $1.4

divide both sides of the equation by 0.035

p = $40

Answer:

2 hours, 15 minutes

B.

Step-by-step explanation:

5:30 to 5:45 is 15 minutes elapsed time.

2 hrs + 15 mins =2 hrs 15 mins.

Answer:

2 hours and 15 minutes

Step-by-step explanation:

You subtract 5:45 - 3:30 = 2:15

Step-by-step explanation:

2y + 14.6m + 3.8 - 34.8m - 15.6 -2y

-20.2m -11.8

Answer:What happens when the y-intercept is greater than 1?: more than one y-intercept would violate this, since it would mean that there are two outputs for x=0. Therefore, it is not possible for a function to have more than one y-intercept. This function never crosses the y-axis because, since you can't divide by zero, it is undefined at x=0.

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

Nothing special happens when the y-intercept is above or below the value of 1. The y-intercept is where the function's graph intersects the y-axis.

When the y-intercept is greater than 1, the graph intersects the y-axis above the point (0, 1).

When the y-intercept is less than 1, the graph intersects the y-axis below the point (0, 1).

__

The meaning of the y-intercept will depend on what the graph is modeling. No information about that is provided here.

Answer:

4

Step-by-step explanation:

The slope of the line is given. It is 4. Use the equation y=mx+b to answer the other questions.

Substitute 1 in for y, 4 in for m, and 2 in for x and solve for b. The equation would look like 1=4(2)+b.

Solving that equation will give you b=-7

That means the y-intercept is -7.

The equation would then be y=4x-7

Answer:

Option A wilk be the correct answer.

Answer:

a. acute, equilateral

Step-by-step explanation:

From the picture the lines on the triangle mean that the sides are equivalent to one another so from that you can eliminate option c. There are not right angles within the triangle so you can eliminate option b. The angles are less than 90 degrees as they arent even cloe to being a right angle so they arent obtuse so you can eliminate option d. Now you are only left with option a.

Answer:

option c is the correct answer

Answer:

Step-by-step explanation:

Let the cost of one soft taco = s

Let the cost of one burrito  = b

So  we have this system

3s  + 3b  = 11.25  

4s +  2b   = 10.00   (1)

Divide  the first equation through by 3   and we have that

s +  b  =  3.75         subtract  b from both sides

s   =  3.75 - b   (2)

Sub  (2) into (1)  and we have

4 (3.75 - b)  +  2b  =  10.00      simplify

15 - 4b  + 2b   = 10.00

-2b + 15  =10.00      subtract 15 from both sides

-2b  =  - 5.00         divide both sides by -2

b  = 2.50

And using (2)

s  =  3.75 - 2.50   =   1.50

So...  a soft taco  1.50 and a burrito is  2.50

Answer: 87

Step-by-step explanation:

42 + 51 = 93 then 180 - 93 = 87

Answer: B

Step-by-step explanation:

Applying limits, it is found that the end behavior of the graph is:

B. As [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex], and as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex].

The function is:

[tex]h(x) = -2x^5 + 8x^4 - 2x^2 + 15[/tex]

To find the end behavior, we apply the limits as x goes to infinity, in which just the term with the highest exponent is considered, hence:

[tex]\lim_{x \rightarrow -\infty} h(x) = \lim_{x \rightarrow -\infty} -2x^{5} = -2(-\infty)^5 = -2(-\infty) = \infty[/tex]

Then, as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex]

[tex]\lim_{x \rightarrow \infty} h(x) = \lim_{x \rightarrow \infty} -2x^{5} = -2(\infty)^5 = -2(\infty) = -\infty[/tex]

Then, as [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex]

Hence, option B is correct.

Step-by-step explanation:

Answer:

[tex]x\geq -6[/tex]

Step-by-step explanation:

The domain of a function is all of the values that [tex]x[/tex] can be under that specific function. In this case, we're asking what values of [tex]x[/tex] allow [tex]\sqrt{\frac{1}{3} x+2}[/tex] to exist.

In order for square roots to exist, the quantity under the square root must be greater than or equal to [tex]0[/tex], because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for [tex]x[/tex]:

[tex]\frac{1}{3}x+2\geq 0[/tex]

Solving this inequality, we get:

[tex]\frac{1}{3}x+2\geq 0[/tex]

[tex]\frac{1}{3}x\geq -2[/tex] (Subtract [tex]2[/tex] from both sides of the inequality to isolate [tex]x[/tex])

[tex]x\geq -6[/tex] (Multiply both sides of the inequality by [tex]3[/tex] to get rid of [tex]x[/tex]'s coefficient)

"The number of boys is 45 the number of girls,"

or to say,

"The ratio of the number of boys to the number of girls is 45:1."

This second interpretation reflects the fact that 45 is the unit rate (which is a number) for the ratio 4:5.
