Answer:

110 feet

Step-by-step explanation:

Given that,

Length of the rectangular garden = 9 1/4 feet = 37/4 feet

Width of the rectangular garden = 4 1/2 feet = 9/4 feet

We need to find the total length of fencing Mark needs to surround all 4 gardens.

The length for 1 garden = perimeter of the garden

The length for 4 garden = 4×perimeter of the garden

= 4×2(l+b)

=8(l+b)\\\\=8(\dfrac{37}{4}+\dfrac{9}{2})\\\\=8\times 13.75\\\\=110\ \text{feet}

Hence, 110 feet is the total length of the fencing Mark needs to surround all 4 gardens.

The estimated quotient of 895 divided by 19 is what number?a. 40 b. 45 c. 55 d. 60
Ira Lisetskai [31]

Answer:

b. 45

Step-by-step explanation:

895 ÷ 19 = 47.1

47.1 rounded is 50, but since there is no 50 option, we'll just round it down to 45.

--

another way:

round 895 (900) and 19 (20)

divide:

895 ÷ 20 = 45

you'll get 45 either way :)

How much do you save per class by taking the longer-term class: Weight Training, $200 for 18 weeks (54 classes) or $350 for 36 w
Vsevolod [243]

<u>Shorter term class:</u>

You pay $200 for 54 classes in total. So,

\frac{200}{54} =3.704 dollars per class (rounded to 3 decimal places)


<u>Longer term class:</u>

You pay $350 for 108 classes in total, So,

\frac{350}{108} =3.241 dollars per class (rounded to 3 decimal places)


Hence, by taking longer term classes, you save around 3.704-3.241=0.463 dollars.

Rounding to 2 decimal places, you save $0.46 per class.


ANSWER: You save $0.46 per class.

For this case we have that by definition, the point-slope equation of a line is given by:

y-y_ {0} = m (x-x_ {0})

Where:

m: It's the slope

(x_ {0}, y_ {0}): It is a point through which the line passes

According to the statement data we have:

m = 5\\(x_ {0}, y_ {0}): (- 8,1)

Substituting we have:

y-1 = 5 (x - (- 8))

By law of signs of multiplication we have to:

- * - = +\\y-1 = 5 (x + 8)

Answer:

The requested equation is: y-1 = 5 (x + 8)
