question
(60-5.8) ÷ 5 - 3^2
explain in an essay how to do this TY!!

Answers

Answer:

(60-5.8) ÷ 5 - 3² = 1.84 (approx)

Step-by-step explanation:

(60-5.8) ÷ 5 - 3²

First simplify the numbers inside the bracket.

(60-5.8) = 54.2

Now, the equation is in the form of,

54.2 ÷ 5 - 9

Put 54.2 ÷ 5 in a bracket for easy calculation.

(54.2 ÷ 5) - 9

Now simplify the numbers inside the bracket again, 54.2 ÷ 5 = 10.84

Subtract 9 from 10.84

10.84 - 9

You will now get the answer as,

1.84 (approx)

Dallas, Texas has an elevation of 200 feet above sea level. The city of Jacksonville is 300 feet less than the elevation of Dallas. Select all options that apply to Jacksonville. at sea level below sea level above sea level elevation of -100 feet elevation of 100 feet

Answers

Answer:

below sea level;

-100 feets

Step-by-step explanation:

Given that:

Dallas, Texas elevation = 200 feets

Jacksonville = 300 feets less than elevation of Dallas

Hence, elevation of Jacksonville :

Dallas elevation - 300 feets

200 feets - 300 feets = - 100 feets

Hence Elevation of Jacksonville city is - 100 feets

-100 feets, means elevation of Jacksonville city is below sea level (elevation points less than 0, are below sea level).

What is the value of x in the figure
below?
PLEASE Help

Answers

Answer:

C) x = 50°

Step-by-step explanation:

In this figure, you can find x by first finding the three angles of the triangle and then applying the Vertical Angle Theorem. First, you need to find the angle in the top right. You can do this by subtracting 95 from 180 since 95 and the missing angle are supplementary:

180 - 95 = 85°

Now, you know two of the angles in the triangle: 85° and 45°. The angles of a triangle add up to 180°; you can use this knowledge to find the triangle's third angle:

85 + 45 + t = 180 (where t is third angle)

130 + t = 180

t = 50°

Now that you know the measure of the third angle, you can apply the Vertical Angles Theorem to find x. The Vertical Angles Theorem states that if two lines intersect, the vertical angles are equal. x is the vertical angle pair for the 50° angle, and therefore x must equal 50°.

Hey there!

To solve this, we can use the linear pair theorem for the 95 degree angle and the missing angle next to it. That gives us 85.

Next, we can use the angles sum theorem for a triangle, and solve for the angle across from x. That gives us 50.

Lastly, we can use the vertical angles theorem, which shows us that x is equal to the angle opposite from it, or 50.

15.D

16.A

Step-by-step explanation:

Hello There!

For 15

We can find the slope given two points by using the slope formula

[tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

so given the two points (2,-3) and (-2,5)

we plug in the y values and x values into the formula

[tex]slope=\frac{5-(-3)}{-2-2} \\5-(-3)=8\\-2-2=-4\\slope=\frac{8}{-4}[/tex]

Finally we want to simplify

8/-4=-2

so we can conclude that the slope of a line that passes through the points (2,-3) and (-2,5) is -2 (D)

For 16

The y intercept is at (0,0) meaning that at 0 hours there was no water in the pool

So we can conclude that the pool was originally empty

Write a function equation that represents a line that contains the two points (-3, 5) and (2, 10).

Answers

Step-by-step explanation:

1. 1st of all calculate the gradient

( - 3, 5) ( 2, 10)

Gradient = (10 - 5) / ( 2--3)

= 1

2. Then find the eq

Y = mx + c

Where m is the gradient

y= 1x + c

Now replace any 2 coordinates from above in the eq.

For ex I'm taking (2, 10)

Y = 1x + c

In the coordinate, x = 2 and y =10

By replacing this in the eq, I will find c

10 = 1(2) + c

2 + c = 10

c = 10 - 2

= 8

So the eq is y = x + 8 ⬅️
