Answer:

The answer is $10.

Step-by-step explanation:

If eight avocados is equal to four dollars, then sixteen (eight times two) is equal to eight dollars. Since you can't add another eight avocados to get twenty, you would add half of eight, which would also be half of the cost of eight. Adding four to sixteen gets you to twenty and adding two dollars to eight gets you to ten dollars.

A system of linear equations in two variables can have _____ solutions

valina [46]

If the lines are parallel (have the same slope but different intercepts) . . .
   no solution, because they never cross.

If the lines have different slopes . . .
   one solution, because they have exactly one common point.

If the lines have the same slope and the same intercept . . .
   infinitely many solutions, because every point on one line is also a point on
   the other line, one lays right on top of the other, and when you look at them on
   the graph, it looks like only one line.

The round wading pool at the Greenville Community Center has a diameter of 8 feet. What is the pool's circumference? use 3.14 fo

HACTEHA [7]

The circumference of pool is 25.12 feet

Solution:

Given that round wading pool at the Greenville Community Center has a diameter of 8 feet

Therefore,

Diameter = 8 feet

We know that,

$Radius = \frac{diameter}{2}\\\\Radius = \frac{8}{2}\\\\Radius = 4$

Thus radius is 4 feet

The circumference of circle is given by formula:

$C = 2 \pi r$

Where, "r" is the radius of circle

Substitute r = 4

$C = 2 \times 3.14 \times 4\\\\C = 25.12$

Thus circumference of pool is 25.12 feet

Please help me if you can. please show how you got the answer.

Answer:

Step-by-step explanation:

The area of a circle is A = πr², where r is the radius. That means in order to solve this we have to find the value of x, which is the diameter of the lake, and then divide it in half to get the radius. To find x we will use similar triangles and proportions. x is the height of the big triangle and 4.5 is the height of the smaller triangle; 15.3 + 7.4 is the hypotenuse of the big triangle and 7.4 is the hypotenuse of the smaller triangle. Setting up our proportion:

$\frac{x}{4.5}=\frac{15.3+7.4}{7.4}$ which simplifies a bit to

$\frac{x}{4.5}=\frac{22.7}{7.4}$ and cross multiply to solve for x:

7.4x = 102.15 so

x = 13.8 That is the diameter of the lake. Divide it in half to get 6.9, the radius. Applying the area formula for a circle:

A = (3.14)(6.9)² and

A = 3.14(47.61) so

A = 149.5 which rounds to 150, Choice C

What is the slope of a line perpendicular to 3x- 2y= 6

Tema [17]

Answer:

y = (-2/3)x + 5

2y=3x-6 Then divide by 2. y=3/2x-6 Now it is in slope-intercept form. The slope for this particular equation is 3/2 (m). The slope of a line that is perpendicular to this would be -2/3, the negative reciprocal of 3/2.
