Answer:

Pentagon is 8

Square is 12

last question is 36

Step-by-step explanation:

if we know that circle is 7, subtract that from 27. You now have 20. So take out the circle in the second problem.

<u>Pentagon</u> + Square = 20 .

<u>Pentagon</u> +<u>Pentagon</u> + Sqaure =28. Adding a Pentagon to the third problem makes it go from 20 to 28. Looking at the second problem you know that 8 + Square = 20. Subtract 8 from 20. You now have 12.

Square = 12.

Answer:

Circle = 7

Pentagon = 8

Square = 12

Square + Square + Square = 36

Step-by-step explanation:

Since you know the circle is 7, the square plus the pentagon must be 20. That means the pentagon in the third equation is 8. This means the square is 12.

So, 12 + 12 + 12 = 36.

Find the equation of the line that passes thru (-1,-5) and is parallel to 3x+y=-5. Show work.
sertanlavr [38]

Answer:

y=-3x-8

Step-by-step explanation:

slope-intercept form:

y=mx+b

Start with the given equation, and to find the slope, convert it to slope-intercept form by solving for y.

3x+y=-5

In this case, all you need to do is subtract 3x from both sides.

y=-3x-5

Here, the slope is -3. The slope of a parallel line will also be -3.

Now, we have 3 known variables. We have the slope and the x and y of a known point. Use those 3 knowns to solve for the 1 unknown, the y-intercept.

y=mx+b\\-5=(-3)(-1)+b\\-5=3+b\\-8=b\\b=-8

Finally, with the slope and the y-intercept, you can write the equation of the line:

y=-3x-8

Jane has a circular garden with a diameter of 16 feet if one bag of fertilizer covers 30 ft.² how many bags will she need to cov
AleksAgata [21]

Answer:

She need 7 bags to cover the garden

Step-by-step explanation:

Diameter of circular garden = 16 feet

Radius of circular garden =\frac{16}{2} = 8 feet

Area of circular garden =\pi r^2 = \frac{22}{7} \times 8^2 =200.96ft^2

30 sq.feet covered by no. of bags = 1

200.96 sq.feet covered by no. of bags = \frac{200.96}{30}=6.69

Hence She need 7 bags to cover the garden
