Answer:

-4 and -10

Step-by-step explanation:

-4 * -10 = 40 because two negatives multiplied equals a positive.

-4 + -10 =  -14 because when two negatives added together, you get a negative.

Marjorie is building a dog run that is 25'8" long and 8'8" wide. How much fencing will she need if the opening is 3'6" wide and
antiseptic1488 [7]

Answer:

782 in

Step-by-step explanation:

To find the length of fence, we have to find the perimeter first.

Given

Length = l = 25 feet 8 in

Width = w = 8 feet 8 in

Opening = o =3 feet 6 in

So,

we have to convert the lengths into same unit first

So,

l = (25*12)+8 = 308 in

w = ( 8*12) +8 = 104 in

O = (12*3) + 6 = 42 in

Perimeter = 2(l+w)

= 2(308+104)

=2(412)

=824

As the opening does not need fencing

Total fence = P - o

= 824 - 42

=782 in

or

65 feet 2 in ..

Find the common ratio of the geometric sequence 18,-72,288,...
tamaranim1 [39]

Answer:

<em>The common ratio of the geometric sequence is -4</em>

Step-by-step explanation:

<u>Geometric Sequence</u>

A geometric sequence is defined as a series of numbers that follow a fixed pattern: Each term equals the previous term times a fixed number called the common ratio. The recursive formula is:

a_n=a_{n-1}*r

Where r is the common ratio.

We are given three terms of a geometric sequence:

18,-72,288,...

To find the common ratio, just divide each term by the previous term:

\displaystyle r=\frac{-72}{18}=-4

Make sure it's a fixed number and test with the third term:

\displaystyle r=\frac{288}{-72}=-4

Since both numbers coincide, the common ratio of the geometric sequence is -4

What’s 48 rounded to the nearest ten
Marrrta [24]

Answer:

50

Step-by-step explanation:

When you around to the nearest ten, you look at the ones digit, which in this case, is 8. Since that is 5 and above, you would have to round the 4 in the tens digit up to 5, resulting in 50.

A sprinkler is set to water the section of lawn represented by the shaded region in the circle below. which measurement is close
Elden [556K]

Answer:

A = 64.141

Step-by-step explanation:

150/360 = 0.41667

41.667% of the circle is shaded so when we find the area we will multiply ir by 0.41667 to find only the shaded area

A=πr^2 x 0.41667

A = π(7)^2 x 0.41667

A = 64.142
