Answer:

[tex]\Huge\boxed{D}[/tex]

Step-by-step explanation:

Hello There!

To find the answer we want to find the trigonometric ratio for each answer choice

important note;

[tex]sin =\frac{opposite}{hypotenuse} \\\\cos=\frac{adjacent}{hypotenuse} \\\\tan=\frac{opposite}{adjacent}[/tex]

for A,

the opposite of angle X is  12 and the adjacent of angle x is 5

so [tex]tanX=\frac{12}{5}[/tex] therefore A is not the answer

for B,

the adjacent of angle x is 5 and the hypotenuse is 13

so [tex]cosX=\frac{5}{13}[/tex] therefore B is not the answer

for C,

the opposite of angle W is 5 and the adjacent of angle W is 12

so [tex]tanW=\frac{5}{12}[/tex] therefore C is not your answer

for D,

the adjacent of angle W is 12 and the hypotenuse is 13

so [tex]cosW=\frac{12}{13}[/tex] therefore D is your answer

Answer:

B

Step-by-step explanation:

RQ=TV

QS=VU

RS=TU

While proving that 2 triangles are congruent you have to consider the same side for both triangles.

The mistake you made was that you presumed that since both have equal sides they are equal,

In a sense that is true but you have align it in the correct way, in option D) it shows RQ is equal to TU which is wrong, RQ is equal to VT, you have align it in a proper way.

B) ΔRQS ≅ ΔTVU here it is align perfectly to be matched

Answer:

30189.155

Step-by-step explanation:

Recall the compound interest formula :

A = P(1 + r/n)^nt

P = principal = 10000

r = rate = 3.7% = 0.037

n = quarterly = 4

t = 30

A = 10000(1 + 0.037/4)^30*4

A = 10000(1 + 0.00925) ^120

A = 10000(1.00925)^120

A = 10000 * 3.0189155

A = 30189.155

Answer:

1 is 90

2 is 52

Step-by-step explanation:

1 is a right angle so its 90

for 2 angles in a triangle equal to 180

so 180-90-38 is equal to 52

Answer:

C. The degree of dependence among the observation is negligible.

Step-by-step explanation:

The conditions for performing a t-procedure when constructing a t-interval are;

1) The samples observation should be independent of each other

2) The use of a random sample or experiment for the procedure

3) Ensure the normality of the data of the dependent variable

Given that surveys usually involve sampling without replacement from a population which is finite can not be taken as independent Bernoulli trials however, it is allowable to still consider samples independent when they are less than 10% the size of population

Therefore, the reason for the condition is to ensure that the population to sample size ratio is large enough and that the degree of dependence among the observation is negligible.

Answer: 6 sandwiches

Step-by-step explanation:

To get the amount of roast beef that Marissa used you would have to subtract 2 3/4 from 5...which is 2.25 pounds of beef that she used.

Then you would divide 2.25 by 3/8 which is 6... meaning Marisa made 6 sandwiches!

Answer:

the desired range is 2 < t < 12.

Step-by-step explanation:

If the third side is 12 (the sum of 5 and 7), we don't really have a triangle, since the 5-unit and 7-unit sides add up to 12 and lie on the third side (of length 12).

Since triangle ABC is acute, all its angles are between 0 and 90 degrees.  So the third side can be 12 but not greater.  The smallest possible length of the third side is 2, since 5 + 2 = 7.

Thus, the desired range is 2 < t < 12.

Answer:

a) 1000 grams

b) 1250 grams

Step-by-step explanation:

Find out how much grams of sausage and dry pasta she needs for each person.

4 people = 400 g

1 person = 400 ÷ 4 = 100 g (sausage)

4 people = 500 g

1 person = 500 ÷ 4 = 125 g (dry pasta)

Find out how much grams of sausage and dry pasta is needed for 10 people.

10 person = 100 x 10 = 1000g (sausage)

10 person = 125 x 10 = 1250g (dry pasta)

Answer:

the diameter is twice the circle radius, or 20

Step-by-step explanation:

Recall that the radius is half the diameter <=> the diameter is twice the radius.  In this problem we need to find the radius first, then multiply it by 2 to obtain the diameter.

We need to determine the distance between the center of the circle Q(6, -4) and the point R(14, 2) on the circle.  

The Pythagorean Theorem applies here.  Going from Q to R, x changes from 6 to 14, or 8 units, which is the horizontal leg of a right triangle, and y changes from -4 to 2, or 6 units.  Thus, according to the Pythagorean Theorem, the length of the hypotenuse of this triangle is

r = √(6² + 8²) = √100 = 10

and so the diameter is twice that, or 20.

Answer:

Option A is the correct answer

Step-by-step explanation:

[tex] - 1 \leqslant x \leqslant 6[/tex]

The domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a given a graph of a function in the picture.

As we can see, the at point x = -1 graph starts, and it has dark dot which means function values exist at x = -1.

Similarly, at x = 6 the function value exist.

The domain of the function:

-1 ≤ x ≤ 6

Thus, the domain of the function is -1 ≤ x ≤ 6 or x ∈ [-1, 6] option (A) -1 ≤ x ≤ 6 is correct.
