Answer:

7 ( x - 0.75 ) = 2.80

Step-by-step explanation:

7 ( x - 0.75 ) = 2.80

7x - 5.25 = 2.80

7x = 2.80 + 5.25

x = 8.05/7

x = 1.15

------------------------------

1.15 - 0.75 = 0.4

(0.4)*7 = 2.8

The volume of an ice cream cone is 500cm^3. The height of the cone is 16cm. What is the approximate diameter of the base of the
olga55 [171]
Volume = πr²h/3
Here, V = 500
h = 16

Substitute their values, 
500 = r² * 22/7 * 16/3
500 = r² * 352/21
r² = 500*21 / 353
r² = 10500 / 353
r² = 29.74
r = √29.74
r = 5.45

Now, diameter = 2 * radius = 2 * 5.45 = 10.90 cm

So, Your Final Answer would be 10.90 cm


Hope this helps!

Find the slope and y-intercept for the two linear functions. Linear Functions Identify the slope of the line given in the table:
Natalija [7]

ANSWER

See explanation

EXPLANATION

The table contains these two points (-4,-3) and (2,-4.5)

The slope of this line is given by;

m =  \frac{rise}{run}

m =  \frac{ - 4.5 -  - 3}{2 -  - 4}  =  \frac{ -  1.5}{6}

m =  -  \frac{1}{4}

The y-intercept can be obtained by finding the equation of the line in the form:

y = mx + c

We plug in the slope and the point (-4,-3) to find c.

This implies that,

- 3 =  -  \frac{1}{4}  \times  - 4 + c

- 3 = 1 + c

c =  - 3 - 1 =  - 4

Hence the y-intercept is -4.

The given line is

y =  \frac{3}{2} x + 1

This is already in the slope intercept form:

The slope is

m =  \frac{3}{2}

The y-intercept is c=1
