in a 30-60-90 triangle, What numerical value do u always put in the master triangle for hypotenuse

Answer:

C is actually the correct answer. Cos formula is adjacent/hypotenuse!

Step-by-step explanation:

The cosine ratio for the given figure is cos θ = 12/13. Therefore, option C is the correct answer.

We need to find which is the correct cosine ratio for the given figure.

The cosine of an angle is the ratio of the length of the side adjacent to the angle divided by the length of the hypotenuse of the triangle.
That is cos θ=Adjacent/Hypotenuse.

From the given figure, cos θ = 12/13

The cosine ratio for the given figure is cos θ = 12/13. Therefore, option C is the correct answer.

A ratio shows us the number of times a number contains another number.

Since For every 5 hardcover books a teacher buys, he or she can get 2 paperback books for free. Therefore, the ratio of hardcover books to paperback books will be,

Hardcover/paperback = 5/2

Using the same ratio for 35 hardcover books,

35/Paperbook = 5/2

(35×2)/5 =Paperbook

Paperbook = 14

Hence, the number of paperback books Ms. Baldwin get for free is 14.

Step-by-step explanation:

Since each cookie has 9 grams of fat, four cookies would contain 4*9 = 36 grams of fat.

Also nine cookies has 7*9 = 63 grams of fat.

So the number of grams consumed will be at least 36 and no more than 63.

The number of grams consumed will be; at least 36 and no more than 63.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We have been given that  cookie contains 9 grams of fat and eat no fewer than 4 and no more than 7 cookies, then;

Since each cookie has 9 grams of fat, four cookies would be;

4 x 9 = 36 grams of fat.

Also, the nine cookies have 7 x 9 = 63 grams of fat.

Therefore, the number of grams consumed will be; at least 36 and no more than 63.

Answer:

n=-0.425

Step-by-step explanation:

subtract 16.2 from both sides. divide 8 from both sides

Answer:

N= -1.825

Step-by-step explanation:

First, we must isolate the variable. So we can write 8N+16.2=1.6. Let's subtract 16.2 from both sides of the equal sign. So now we have 8N=-14.6. Now we have to only get N, so we must divide every side by 8. We do this to cancel out the 8 multiplying the N. We get N= -1.825. This is your answer!

This is the general rule for any function, where a function cannot have more than one x value for every y value, there is only one output for every input.

You can also use the vertical line test which states that anything that hits the line more than once is not a function.

Answer:

Kennet 25,Andrew 15,Billy 30,Cameron 7

Step-by-step explanation:

Kenneth - 10+x,

Andrew - x,

Billy - 2x,

Cameron - x - 8,

10 + x + x + 2x + x - 8 =77

5x = 75

x = 15 (Andrew)

10+15= 25 (Kenneth)

2×15=30 (Billy)

15-8= 7 (Cameron)

2x + 4y = 110

Step-by-step explanation:

Let

The quantity of small tables = x

The quantity of large tables = y

The smaller tables can fit 2 people, the larger tables can seat 4 people.

Equation that describes the relationship between the quantity of small tables and the quantity of large tables, assuming exactly 110 people need seats.

Number of people×quantity (small table) + number of people×quantity (large table) = 110

2x + 4y = 110

Answer:

100x+75=y

Step-by-step explanation:

Answer:

y=100x+75. Where y equals total cost and x equals numbers of weeks enrolled.

Step-by-step explanation:

75 is the upfront cost, aka the cost of zero weeks, this cost will never change and is a one-time payment, therefore it needs no variable. 100 is the cost per week which means every week costs 100 more dollars, this is why it must have a variable because it will change with time. They are added together because they both show the total cost and together will show how much one person is spending.

Answer:

The equation is  [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

The Equation is formed from two sides equal to each other

∵ One eighth means [tex]\frac{1}{8}[/tex]

∴ Negative one eighth means  [tex]-\frac{1}{8}[/tex]

→ Assume that the number is x

∵ "of" means times

∴ Negative one eighth of a number = [tex]-\frac{1}{8}[/tex] × (x)

∴ Negative one eighth of a number = [tex]-\frac{1}{8}[/tex] x

∵ Negative one eighth of a number is [tex]-\frac{3}{4}[/tex]

→ "is" means equal, so the left side is [tex]-\frac{1}{8}[/tex] x and the right side is [tex]-\frac{3}{4}[/tex]

∴  [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex] ⇒ Equation

∴ The equation is  [tex]-\frac{1}{8}[/tex] x = [tex]-\frac{3}{4}[/tex]

Answer:

Step-by-step explanation:

put x=8

y=1/8×8+3=1+3=4

so point is (8,4)

put x=0

y=1/8×0+3=0+3=3

so point is (0,3)

to find more points put x=multiple of x and then find y.
