Suppose c = 5 and A = 85 degrees.

Answers

Answer:

a = 4.98

b = 0.44

B = 5

Concept:

Here, we need to know the idea of the Pythagorean theorem and basic trigonometry ratios.

Pythagorean theorem: a² + b² = c²

a = legb = legc = hypotenuse

Trigonometry ratios:

Sine = Opposite / Hypotenuse = O/HCosine = Adjacent / Hypotenuse = A/HTangent = Opposite / Adjacent = O/A

Solve:

**Disclaimer** The question did not clarify which place did it required to be rounded to as some of the values are infinite. I rounded to the hundredth place. If it is fine, then you may refer to my answers. If it is not, then you may tell me and I'll redo it.

Given information

c = 5

A = 85°

PART ONE: Find the value of [a]

sin (A) = Opposite / Hypotenuse = a / c

sin (85) = a / 5

a = 5 · sin (85)

a = 4.98

PART TWO: Find the value of [b]

cos (A) = Adjacent / Hypotenuse = b / c

cos (85) = b / 5

b = 5 · cos (85)

b = 0.44

PART THREE: Find the value of [B]

Since the triangle as a right angle sign, meaning it is a right triangle.

Therefore, the corner angle is 90°.

90 - 85 = 5°

Hope this helps!! :)

The double bar graph shows how long, on average, different

Which animal's life span in captivity has the least difference from
its life span in the wild?
ears

Answers

Answer: Cheetah

Step-by-step explanation: I got it right on the test :)

The animal with the least difference is cheetah with a value of 5

From the double bar chart attached :

Life span in wild is = blue bar

Life span in wild is = blue bar Life span in captivity = brown bar

Calculating the approximate difference between the two bar values as obtained from the graph :

CHEETAH = 17 - 12 = 5

POLAR = 35 - 20 = 15

TIGER = 26 - 20 = 6

GIANT PANDA = 30 - 20 = 10

LEOPARD = 28 - 20

The animal with the least difference between it's span in the wild and in captivity is CHEETAH with a value of 5.

using the variable n write an algebraic expression for a number increased by 6

Answers

The answer you are looking for is simply just n+6.

Solution/Explanation:

If you use the variable "n" to write an algebraic expression, for a number increased by 6, you must write it like this:

n+6.

And, also, increase obviously means the same thing as adding.

So, therefore, "n" stands for the number in this algebraic expression, and if you add 6 to that number "n," it must be n+6.

So, therefore, the final answer is n+6.

-21 - 8a = -5(a +6)
Step by step if possible

Answers

Answer:

Step-by-step explanation:

First multiply the -5 to (a+6)

The equation will look like this

-21 - 8a = -5a -30

then move the numbers around where you have a value times on one side, and a normal value on the other

add -5a to -8a, and add -21 to -30

the equation should look like this:

-13a = -51

then you need to get the a by itself, so divide -13 by -51

a= 13/51 (as a fraction with 13 on top)

Answer:

a = 3

Step-by-step explanation:

-21 - 8a = -5(a + 6)

-21 - 8a = -5a - 30

8a + (-5a) = 30 - 21

3a = 9

a = 9/3

a = 3

What is the perimeter?

Answers

Answer:

Perimeter = 16 cm

Step-by-step explanation:

The formula for a square's area  = s^2 where the length of the side is s.

s^2 = 16                   Take the square root of both sides

sqrt(s^2) = sqrt(16)

s = 4

The perimeter is the same

P = 4*s

P = 4 * 4

P = 16

Answer:

16

Step-by-step explanation:

Square root of 16 = 4cm

4 sides, 4 * 4 = 16cm

[tex]\frac{sin\left(90\right)}{x}=\:\frac{sin\left(60\right)}{\left(\frac{\left(6\cdot \:sin\left(90\right)\right)}{sin\left(45\right)}\right)}[/tex]

Step-by-step explanation:

Answer: 4sqrt(6)

Explanation:

Sin(theta) = opp/hyp => hyp = opp/sin(theta)

Find opp:

opp = sqrt(6^2 + 6^2)
= sqrt(72)
= 6sqrt(2)
= 6 x 1.41

Hyp(also is x) = (6 x 1.41)/Sin(60°)
= (6 x 1.41 )/0.86
= 9.83
= 10 (round up)

And 4sqrt(6) = 9.79 = 10 (round up)

Thus I concluded that x = 4sqrt(6)

there are 14 math teachers and 26 science at school today what is the ratio of math teachers and science at school?

Answers

Answer:

Answer is 7:20

It's basically asking "what is the ratio of math teachers to total teachers?" assuming there are only math and science teachers at this school. For the sake of simplicity, let's just go with that. We have 14 math teachers and 14+26 = 40 teachers total. The ratio of math to total is 14:40 which reduces to 7:20 when we divide both parts of the ratio by the GCF 2.

Step-by-step explanation:

Answer:

the ratio is

14:26

but you can leave the answer like this the two numbers can be divided by 2 so

14/2=7 and 26/2=13

then the answer is 7:13.

Vertex is (-8, 4)  not one of the answers offered!

Step-by-step explanation:

Factor -1/8 out of the first two terms. Leave a space inside parentheses in which to add a number.

[tex]y=-\frac{1}{8}(x^2 + 16x + \text{-----})-4[/tex]

Complete the square by squaring half the coefficient of x and adding it in the space.

[tex](\frac{16}{2})^2=64[/tex]

Add 64 in the space you made, then compensate for that at the end of the expression by subtracting  [tex]-\frac{1}{8}(64)=-8[/tex]

[tex]y=-\frac{1}{8}(x^2+16x+64)-4+8\\y=-\frac{1}{8}(x+8)^2+4[/tex]

The x-coordinate of the vertex is the opposite of +8, the number inside the parentheses.  The y-coordinate of the vertex is the number at the end of the expression.

We find a slope between two arbitrary  pair of points( arbitrary means what the question given us). One point we are given is (0,4) and an another point we are given is (2,1).
