Answer:

Perimeter for first shape = 38 ft

Perimeter for second shape = 40 inches ..

Step-by-step explanation:

First we will define the perimeter.

The continuous line which forms the boundary of a closed geometric figure.

To find the perimeter of any geometrical shape the lengths of its outer boundary lines are added.

So for the first shape with sides 10ft, 4ft, 3ft and 9ft, we don't know the lengths of two sides

1. The side parallel to the 10ft side

and

2. The side parallel to 9ft side.

So the lengths of side will be:

For 1,

10-3 = 7ft

For 2,

9-4= 5ft

the perimeter will be:

=> 10+4+3+9+5+7

=> 38 ft

And for the second shape with sides 6 in ,5 in, 4 in, 3 in, 2 in and 10 in,

the length of one unknown side will be 6 inches as it is parallel and equal in length to the side with 6 in length,

And the length of side that is parallel to the side with length 4 inches will be same.

The perimeter will be:

=>6+5+4+3+2+10+6+4

=> 40 inches

So,

Perimeter for first shape = 38 ft

Perimeter for second shape = 40 inches ..

To find perimeter all you need to do is add each side together.

1) 10 + 9 + 4 + 3 = 26

2) 10 + 6 + 5 + 4 + 3 + 2 = 30

Write 70 cm as a fraction of 4.2 m. Give your answer in its simplest form.

kaheart [24]

Answer:

1/6

Step-by-step explanation:

First convert 4.2m to cm

100cm = 1m

x = 4.2m

x = 4.2 * 100

x = 420cm

70cm to 420cm = 70/420

70/420 = 7/42

7/42 = 1/6

Hence 70 cm as a fraction of 4.2 m is 1/6

Which equation represents the function graphed on the coordinate plane?????

Y_Kistochka [10]

Since you haven't provided the graph, I'll explain each one and you choose the one suiting your given.

The parent modulus function is:

g(x) = |x|

It is centered at the origin and opens upwards.

A coefficient inside the modulus |x+k| means that the function is shifted along the x-axis

If "k" is positive, the shift will be to the left. If "k" is negative, the shift will be to the right.

A coefficient outside the modulus |x| + h means that the function is shifted along the y-axis

If "h" is positive, the shift will be upwards. If "h" is negative, the shift will be downwards.

Now, let's check each of the options:

g(x) = |x+4| - 2 :

This function is shifted 4 units to the left and 2 units down. It will be centered at (-4,-2). Check the blue graph in the attachment.

g(x) = |x-4| - 2 :

This function is shifted 4 units to the right and 2 units down. It will be centered at (4,-2). Check the black graph in the attachment.

g(x) = |x-2| - 4 :

This function is shifted 2 units to the right and 4 units down. It will be centered at (2,-4). Check the red graph in the attachment.

g(x) = |x-2| + 4 :

This function is shifted 2 units to the right and 4 units up. It will be centered at (2,4). Check the green graph in the attachment.

All 4 graphs are shown in the attached picture.

Hope this helps :)

Helen [10]

Answer:

$\frac{1}{2}$ is the probability for picking fruits and it will be apple.

Explanation:

probability of picking apple: $\boxed{\frac{total -apples}{total-fruits} }$ → $\frac{4}{8}$ → $\frac{1}{2}$
