A school field is 10 m wide and 50 m length. If a fence is put all around. What will be the total length of the fence
kykrilka [37]
Hi there!

We are looking for the circumference of the school field. When we assume that the field is a rectangle, we can use the following formula for finding its circumference.

Circumference = 2 × length + 2 × width
Plug in the length and width from the question.

Circumference = 2 × 50 + 2 × 10
Multiply first (remember: PEMDAS).

Cirxumference = 100 + 20
And finally add.

Circumference = 120.

Hence, the total length of the fence will be 120 meters.
~ Hope this helps you!

5^0×2^1 help me please
tankabanditka [31]
Starting with 5^0 (since in PEMDAS, we have parenthesis, exponents, multiplication, division, addition, and subtraction, and exponents come before multiplication), we know that anything to the power of 0 equals 1. Therefore, 5^0=1. Next, for 2^1, anything to the power of 1 means it's that number, so 2^1=2. Note that for 2^3 (and for most exponents), however, it's 2 multiplied by itself 3 times, or 2*2*2=8. Since 5^0=1 and 2^1=2, 5^0*2^1=1*2=2

Sam wants to fence his rectangular garden plot along its length on the front side. The perimeter of the plot is 24 meters, and i
Black_prince [1.1K]

Question is Incomplete;Complete question is given below;

Sam wants to fence his rectangular garden plot along its length on the front side. The perimeter of the plot is 24 meters, and its length is 3 times its width. If x is the length and y is the width of the plot, set the equations of the system. Solve and determine the values of x and y. If the cost of fencing is $25 per meter, how much does Sam need to spend on fencing?

Answer:

Length of the plot (x) is 9 meter and width of the plot (y) is 3 meter.

Sam need to spend $225 on fencing.

Step-by-step explanation:

Given;

Perimeter of the plot =24 m

Length of the plot is denoted 'x'

Width of the plot is denoted by 'y'

Cost of Fencing = $25 per meter.

We need to find the the values of x and y.

Also we need to find how much does Sam need to spend on fencing.

Solution:

Now given that;

length is 3 times its width.

so we get;

x=3y

Now we know that;

Perimeter of the rectangle is equal to 2 times sum of its length and width.

framing in equation form we get;

24=2(x+y)

But x=3y

so we get;

24 =2(3y+y)\\\\24=2(4y)\\\\24=8y

Dividing both side by 8 we get;

\frac{24}{8}=\frac{8y}{8}\\\\y =3\ m

Now width of the plot = 3 meter

Length of the plot x=3y=3\times3= 9\ m

Hence Length of the plot (x) is 9 meter and width of the plot (y) is 3 meter.

Now given that;

Sam wants to fence his rectangular garden plot along its length on the front side.

So we can say that;

Length to be fenced = 9 m

Cost of fencing = $25/meter

Cost of fencing the garden = 9\times 25= \$225

Hence Sam need to spend $225 on fencing.

15 crackers weigh 69 grams. how many kilograms is this?
Marrrta [24]

Answer:

0.069\ kg

Step-by-step explanation:

we know that

1 kg=1,000 g

so

using proportion

Find out how many kilograms are 69 grams

Let

x -----> the weight in kg

\frac{1}{1,000}\frac{kg}{g} =\frac{x}{69}\frac{kg}{g}\\\\x=\frac{69}{1,000}\\\\x=0.069\ kg
