Calculate the value of x

Answer:

A. 13.3

General Formulas and Concepts:

Pre-Algebra

Trigonometry

Step-by-step explanation:

Step 1: Set up equation

tan55° = 19/x

Step 2: Solve for x

And we have our final answer!

Answer:

13.3

Step-by-step explanation:

This is trigonometry

So for this one, we use a basic ratio. We need to use 19 and 55 degrees for the answer. We are given that the leg adjacent to the 55-degree angle is x and the opposite leg to the 55-degree angle is 19.

So we use tangent(opposite leg/adjacent leg) for this (TOA of SOH CAH TOA)

tan(55 degrees)=19/x

  SO then solve for x and then evaluate using a scientific calculator and you should get 13.30394322

Answer:

The mixture C is the correct option

Step-by-step explanation:

According to the given scenario, the calculation is as follows:

For Mixture A

Blue Paint - 5 cups

White Paint - 12 cups

The ratio between them is 5:12

For Mixture B

Blue Paint - 6 cups

White Paint - 6 cups

 The ratio between them is 6:6 = 12:12

It came by multiply the numerator and denominator by 12

For Mixture C

Blue Paint - 4 cups

White Paint - 12 cups

 The ratio between them is 4:12

For Mixture D

Blue Paint - 5 cups

White Paint - 6 cups

 The ratio between them is 5:6 = 10:12

It came by multiply the numerator and denominator by 12

As it can be seen that in all four mixtures the denominator is the same so for calculating the lowest ratio we have to see the small value in the numerator

As it can be seen that there is a small value of 4

hence, the mixture C is the correct option

Answer:

first share 2x=36

Second share=5x=90

Step-by-step explanation:

Ratio 2:5

Share=126

Let first share=2x

Second share=5x

So 2x+5x=126

7x=126

X=126/7

X=18

So first share 2x=36

Second share=5x=90

the equivalent expressions are:

And the expression in scientific notation is the last one in the bullet points.

Here we start with the expression:

(9.6*10³)*(6.7*10)

Where both numbers are in scientific notation, notice that we can write that product as:

(9.6*10³)*(6.7*10) = (9.6*6.7)*(10³*10) = 64.32*10⁴

Now, remember that in scientific notation, we only can have a single digit in the left of the decimal point, so we can rewrite:

64.32*10⁴ = 6.432*10⁵

So the equivalent expressions are:

Answer:

It is -5

Step-by-step explanation:

Answer: y=5x+8

Step-by-step explanation:

first you solve for y:
5x - y = 4
-5x       -5x
     ↓
[tex]\frac{-y}{-1}[/tex] = [tex]\frac{-5x+4}{-1}[/tex]
     ↓

y = 5x - 4

slope of given line: 5
slope of a parallel line: 5

plug in slope:
y = 5x + b

find b, which is 8 :)

plug it in!

y = 5x + 8

Answer: B

Step-by-step explanation:

Slope-intercept form is written as y = mx + b, where m is the slope and b is the y-intercept.

From this graph we should determine two points so we can work out the slope. Let's take points (3, -4) and (6, -2).

The equation to find the slope is:

m = [tex]\frac{y2 - y1}{x2 - x1}[/tex]

Let's substitute in our values:

m = [tex]\frac{-2 - -4}{6 - 3}[/tex]

Remember that two negatives make a positive, let's solve for m:

m = [tex]\frac{2}{3}[/tex]

Okay, now we have the value of m. Now we need the value of b. We can determine this by looking at the graph and looking where the line passes through the y-axis. In this graph, we can see the line pass through the y-axis at point (0, -6).

Therefore we can determine that b = -6.

Let's substitute our value for m and our value for b into the slope-intercept formula:

y = mx + b

y = [tex]\frac{2}{3}[/tex]x + -6

There's your final answer! I hope this helps, have a great night. :)
