48 cookies; 25% decrease=?

stepladder [879]

First, you do a proportion. X/48=25/100. 25 times 48 equals 1,200. Now divide 1,200 by 100 which equals 12. This means 12 cookies is 25% of 48 cookies. Now do 48-12 which is 36. YOUR ANSWER IS 36

Janna has three flat plates easy the same size. She stores them in an L shaped drawer as shown so that they fit snuggly inside w

Phantasy [73]

Answer:

258 square centimeters

Step-by-step explanation:

Consider the image attached below.

We can see that the length of each side of L shape is 40 cm and in 2 plates fit in between.

We need to find the are which is not covered by the plates. Let us calculate the area of L shape first.

We can see that it is a square with one fourth of its area missing. So the area of square with side length 40 cm is,

$A_1= 40 \times 40 = 1600 cm^2$ , where ' $A_1$ ' is the area of square.

Now, one fourth of the area is not there in the L shape, so one-fourth of $1600cm^2$ is,

$\frac{1600}{4}= 400 cm^2$

Therefore, the area of L shape drawer is,

$1600-400=1200 cm^2$

Now, we can see that the diameter of each circular plate is, 20 cm. So the radius of circular plate is 10 cm. Let $A_2$ be the area of each circular plate, so,

$A_2= \pi (10)^2=100\pi cm^2$

There are three plates so the total area is,

$A_3= 3\times 100 \pi = 300 \pi cm^2$

$A_3= 300\times 3.14 = 942 cm^2$

Hence, the area not covered by the plates is,

= $1200-942= 258 cm^2$

So, the area not covered by three flat plates is 258 square centimeters.

Find the length of ab

Anvisha [2.4K]

Answer:

$^\frown_{AB}=11.16m$

Step-by-step explanation:

The given circle has radius 8m and a central angle of $80\degree$ .

We want to find the length of arc AB.

Recall that the length of an arc is given by:

$l=\frac{\theta}{360\degree}\times 2\pi r$

where $\theta=80\degree$ is the central angle and $r=8m$ is the radius.

$^\frown_{AB}=\frac{80}{360\degree}\times 2*3.14*8$

This simplifies to:

$^\frown_{AB}=11.16m$

3 /8 + 2/ 3 = 9/ 24 + 16/ 24 = 25/ 24 =

Alchen [17]

Convert the denominator of the first two fractions to 24 since 3 and 8 can fit into 24.

3/8=9/24

2/3=16/24

Now add them together.

9/24+16/24=25/24

Next add the second two fractions 9/24 and 16/24.

9/24+16/24=25/24

Since all fractions equal 25/24, the equation was true!

Hope this helps!
