What is the area of the shaded region <br> 1cm is in the middle

Archy [21]

Answer:

Area of the shaded region= $128.86\,cm^2$

Step-by-step explanation:

Area of the shaded region=Area of the rectangle-Area of the circle

Area of rectangle= $Length\times Width$

$Length=11\,cm\\Width=12\,cm$

Area is:

$=11\times 12\\\\=132\,cm^2$

Area of the circle = $\pi \times r^2$

$r=1\,cm$

As, $\pi =\dfrac{22}{7} =3.14$

Area of the Circle is :

$=3.14\times 1 \times 1\\\\=3.14\times 1\\\\=3.14\,cm^2$

Area of the Shaded region:

Area of the shaded region $=132-3.14\\\\=128.86\,cm^2$

The answer is NO
Because if x=5 the equation is 125+10y=110
In this case y will be a negative
You can’t have a negative oranges
So the answer is NO

Answer:

n=3.5 a=1.41 units a'=4.95 units b3 units b'10.5 units c2.24 units c'=7.83 units

Step-by-step explanation:

This answer assumes that n = 3.5. The ratio of each side length on to the corresponding side length on is equal to 3.5. For example, a′ = 3.5a. The ratio is equal to the scale factor, n.

Need to zoom in can any find these two out for me?

Ber [7]

Answer:

9. Juanita's recipe.

10. Leon's recipe.

Step-by-step explanation:

9. All you need to do is convert the numbers into fractions.

Juanita's recipe: 4 parts lemon, 2 parts sugar. Lydia's recipe: 5 parts lemon and 3 parts sugar. So in order to find the lemon amount in each recipe convert into this fraction:

lemon/sugar

Juanita: lemon/sugar= 4 lemon/2 sugar

Lydia: lemon/sugar= 5 lemon/3 sugar

The LCM is 6 so that is the denominator.

Juanita: 4 lemon/2 sugar= 12 lemon/6 sugar

Lydia: 5 lemon/3 sugar= 10 lemon/6 sugar

The ratio is 4:2= ?:6 and 5:3= ?:6

Juanita has 12 lemon and Lydia has 10, so Juanita has more lemons.

10. Same as number 9.

Use the fraction peanuts/pretzels because it wouldn't work if peanuts is on the bottom otherwise both Leon and Cisco's peanut amount will be the same. SO put peanuts over pretzels, so pretzels will be the denominator so we can find the peanut amount.

peanuts/pretzels

Leon: peanuts/pretzels= 3 peanuts/8 pretzels

Cisco: peanuts/pretzels= 2 peanuts/6 pretzels

The LCM is 24 so that is the denominator.

Leon: 3 peanuts/8 pretzels= 9 peanuts/24 pretzels

Cisco: 2 peanuts/6 pretzels= 8 peanuts/24 pretzels

The ratio is 3:8= ?:24 and 2:6= ?:24

Leon has 9 peanuts and Cisco has 8, so Leon has more peanuts.
