22. Mona is in her garden jumping on stones (as shown below).

iris [78.8K]

$\large\green{\sf\boxed{Given:-}}$

Mona starts from 68th stone

She jumps 23 stones ahead 

Then she jumps 28 stones back

$\large\red{\sf\boxed{To \:find:-}}$

Her final position=?

$\large{|\underline{\mathtt{\red{S}\blue{o}\orange{l}\pink{u}\blue{t}\purple{i}\green{o}\red{n}\blue{:}\orange{-}}}}$

Add 23 in 68 [Given]

$\begin{gathered}\\ \sf\longmapsto 68+23=91\end{gathered}$

Subtract 28 from 91

$\begin{gathered}\\ \sf\longmapsto 91-28=Her\:final\:position\end{gathered}$

$\begin{gathered}\\ \sf\longmapsto =63\end{gathered}$

To find how much stones she is ahead or back we will Subtract 63 from 68 which was her initial position.

$\begin{gathered}\\ \sf\longmapsto 68-63=5\end{gathered}$

So, Mona will be 5 stones behind from the starting stone.

☯️Hence, Option C is correct

What is the change in temperature from 15 degrees to -9 degrees? -6, 6, -24, 25

dalvyx [7]

Answer:

24 degrees

Step-by-step explanation:

The distance from 15 degrees to 0 degrees is 15, and the distance from 0 degrees to -9 degrees is 9, so then the total distance from 15 degrees to -9 degrees is (15+9 degrees) which adds up to be 24 degrees

What is the perimeter of this figure?

krok68 [10]

Answer:

D) 44 inches

Step-by-step explanation:

Isosceles trapezoids have equal legs, which is why they are called isosceles.

Squares have equal side lengths are around, so you know that the missing side lengths to this figure are 5 in, 10 in, and 10 inches.

Add all of the given values together.

5 in + 4 in + 10 in = 19

Add all of the "unknown" values together.

5 in + 10 in + 10 in = 25

Add these two values together.

19 in + 25 in = 44 inches

This answer corresponds to answer choice D.
