A swimming pool at a park measures 9.75 meters by 7.2 meters.

neonofarm [45]

Answer:

Part a) The area of the swimming pool is $70.2\ m^2$

Part b) The total area of the swimming pool and the playground is $105.3\ m^2$

Step-by-step explanation:

Part a) Find the area of the swimming pool

we know that

The area of the swimming pool is

$A=LW$

where

L is the length side

W is the width side

we have

$L=9.75\ m\\W=7.2\ m$

substitute the values

$A=(9.75)(7.2)$

$A=70.2\ m^2$

therefore

The area of the swimming pool is $70.2\ m^2$

Part b) The area of the playground is one and a half times that of the swimming pool. Find the total area of the swimming pool and the playground

we know that

To obtain the area of the playground multiply the area of the swimming pool by one and a half

$\frac{1}{2}(70.2)=35.1\ m^2$

To obtain the total area of the swimming pool and the playground, adds the area of the swimming pool and the area of the playground

$70.2\ m^2+35.1\ m^2=105.3\ m^2$

therefore

The total area of the swimming pool and the playground is $105.3\ m^2$

What are the first four terms of the sequence a1=−9 and an+1=an+n. I really need help with this im struggling

pochemuha

$a_{n+1}=a_n+n$

The formatting was a bit confusing, so please do let me know if this isn't the correct equation for the sequence.

The first term is given, which is

$a_1=-9$

Now, use the equation for the next terms:

$a_{1+1}=a_2=-9+1=-8$

$a_{2+1}=a_3=-8+2=-6$

$a_{3+1}=a_4=-6+3=-3$

Thus, the first 4 terms are -9, -8, -6, and -3. Let me know if you need any clarifications, thanks!

When a figure is translated on a coordinate grid, what conclusion can you draw from the pre-image and image? The orientation cha

blagie [28]

The correct answer is -The position changes, and the angles remain congruent. or C.

The size does not change because the shape is only moving to new coordinates not growing or shrinking.
This means the shape also does not change.
When you translate a shape in geometry it means you are changing the position. But the shape will remain the same, meaning the angles remain congruent.
