Answer:

3 3/4

Explanation:

30/8 is 3.75 which is equal to 3 3/4

or you can see that 8 goes into 30 completely 3 times and then you have 6/8 left over, which simplifies down to 3/4 because 6/2= 3 and 8/2= 4

Answer:

y-intercept: 100 (0, 100)

[tex]y=\frac{8}{7}x+100[/tex]

Step-by-step explanation:

The y-intercept is the point on a graph that crosses the y-axis, this line crosses the y-axis at 100.

slope-intercept form is: [tex]y=mx+b[/tex]

[tex]m=slope[/tex]

[tex]b=y-intercept[/tex]

This line has a slope of 8/7 and the y-intercept is 100 so the equation would be: [tex]y=\frac{8}{7}x+100[/tex]

y=8/3x+100 is the equation of the line in slope-intercept form.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the given graph let us consider two points through which the line is passing.

(0, 100) and (42, 148)

Slope=148-100/42

=48/42=8/3

Now let us find the y intercept

100=8/3(0)+b

b=100

So slope intercept form is y=8/3x+100

Hence, y=8/3x+100 is the equation of the line in slope-intercept form.

The value of x is 17 unit.

The Pythagorean theorem, or Pythagorean theorem, illustrates the relationship between the three sides of a right-angled triangle. The square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle, according to the Pythagorean theorem.

We know,

Kyle held a balloon 8 feet off the ground.

Ava is standing 15 feet directly to the right of Kyle.

So, height = 8 ft and distance = 15 ft

Using Pythagoras theorem

x² = 8² + 15²

x² = 64+ 225

x = 17 unit

Thus, the value of x is 17 unit.

A≈54cm²

Step-by-step explanation:

Answer:

54 cm²

Step-by-step explanation:

Since it's a cube all sides must be equal. So, the length of one side is equal to the cube root of the volume.

∛27 = 3

An area of one surface is 3² = 9

Since the area of all the surfaces of the cube are equal, we can say that the surface area of the cube is 9 x 6, because there are 6 faces on a cube.

9 x 6 = 54

So, this means that the surface area of the cube is 54 cm².
