Answer 1

Answer:

x = 71°

Option B is correct answer.

Step-by-step explanation:

We need to find for what value of x is [tex]sin\: x = cos 19^{\circ}[/tex], where 0°< x < 90°?

Solving:

[tex]sin\: x = cos\: 19^{\circ}\\Finding \:cos\: 19^{\circ}=0.94551\\Putting\:value:\\sin\:x=0.94551\\Now\:taking\:sin\:inverse\\x=sin^{-1}(0.94551)\\x=71^{\circ}[/tex]

a bus travels 320 miles in 6.4 hours. if the bus continues at the same rate, which proportion can be used to find m, the number of miles the bus will travel in 9 hours.

Answers

Answer:

Step-by-step explanation:

Ok first we need to find rate of MILES per HOUR

320/6.4=50

m= miles in 9 hours

9*50=450

Cross Multiply

is your answer

(6.4*9)/320m=Hours/miles

Hope this helps!

The number of miles the bus will travel in 9 hours will be 6.4 / 320 = 9 / m. Then the correct option is B.

What are ratio and proportion?

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A bus travels 320 miles in 6.4 hours. if the bus continues at the same rate.

We know that speed is the ratio of distance and time. Then we have

The number of miles the bus will travel in 9 hours will be

320 / 6.4 = m / 9

6.4 / 320 = 9 / m

Then the correct option is B.

How can you write the equation for a linear function if you know only two ordered pairs for the function? Drag tiles tho complete the explanation. Tiles may be used once, more than once, or not at all.

Answers

Answer:

Explanation below

Step-by-step explanation:

First determine the slope using (y2-y1)/(x2-x1)

Then set up point slope form and add in an ordered pair for x and y to determine the y intercept: y - y1 = m(x - x1). Solve for y and you'll end up with slope intercept form.

For example: (-2,1), (3,2) find slope and y intercept.

(2-1)/(3-(-2))= 1/5

y-2=.2(x-3)

y=.2x-.6+2

y=.2x+1.4 or y=(x/5)+(7/5)

METHOD 1:

If the perimeter of this triangle is 15 centimeters, what is the value of n?
5n - 6
n
2n + 1
Express your answer as a decimal number.

Answers

Answer:

25/14

Step-by-step explanation:

The value of n that makes up the triangle of perimeter 15 centimeters is 2.5

How to determine the value of n?

The side lengths of the triangle are given as:

5n - 6, n and 2n + 1

The perimeter is given as:

P = 15

The perimeter is the sum of the side lengths.

So, we have:

5n - 6 + n + 2n + 1 = 15

Collect like terms

5n + n + 2n = 15 + 6 - 1

Evaluate the like terms

8n = 20

Divide both sides by 8

n = 2.5

Hence, the value of n that makes up the triangle is 2.5

Answers

In this case, we need to substitute n with 10.

So, it is like this: f(10) = 3(10) + 4

f(10) = 3(10) + 4

f(10) = 30 + 4

f(10) = 34
