9 1/3 days
Step-by-step explanation:
- If the total change in the size of the pencil is -7/9 millimeters. Then the actual change itself is 7/9 which is a positive value.
- If each day the pencil changes by 1/12 millimeters, how many 1/12 millimeters are there in 7/9 millimeters. This is a division query;
7/9 ÷ 1/12 = 7/9 * 12/1 = 28/3
= 9 & 1/3 days

As given Zahra has paper rectangles of different sizes.
Also, Every rectangle is 5 cm is longer than it's breadth.
So, if Length=L, then Breadth= L- 5
Or , if Breadth= B, then Length= B+5
or, if length is x and breadth is y ,then writing in terms of equation
→x=y+5
As you can see,there is not any proportional relationship between length and widths of these rectangles.
Answer:
w=2
Step-by-step explanation:
A=length times width (A=lw)
w= l-3
A=10
Substituting in, we get:
10= l(l-3)
Now, solve the equation.
10= -3l
-3l-10=0
(l+2) (l-5)=0 (factoring the equation)
Therefore, l= -2 or 5
Throw out the negative value because a length of rectangle will never be negative.
Now let's solve for width
Remember w=l-3
therefore
(5)-3=2
so, w=2
(honestly, this is easier to just do in your head. But here is the long form math if you happen to run into more complicated problems.)
Ok so the first blank square would be 6, the second would be 48 and the third square would be 10.5 because you would multiply the top number or divide the bottom number by 4. Hope this helps. Happy Thanksgiving
Answer:
28.6 m²
Step-by-step explanation:
The measurements of the square are 4 by 4; this gives us an area of
4(4) = 16 m²
The quarter circle has a radius of 4 m. The area of a circle is given by
A = πr².
Since we have a quarter circle, we multiply this by 1/4:
A = 1/4πr²
Using 3.14 for π and 4 for r,
A = 1/4(3.14)(4²) = 1/4(3.14)(16) = 3.14(4) = 12.56 m²
Together this gives us a total area of 16+12.56 = 28.56 m².
This rounds to 28.6 m².
