Bernie’s estimated that 69% of 242 is 168 is her estimate reasonable

Mathematics

Answer:

Yes it is.

Step-by-step explanation:

Best way is to use percentages you know when estimating.

We know 50% is half.

50% of 242 is 121.

So it has to be more than 121.

10% of 242 is 24.2  so add that to 121 and you get 145.2

You are 60% so far. You just need 9% more.

Add another 10% which is 24.2 and you get 169.4, which is over but we used 10% instead of 9% so the estimate is reasonable and close.

Find the area of the figure in the image attached. Round to the nearest tenth if necessary.
tatyana61 [14]

Answer: 15in^2

Step-by-step explanation:

first you need to find the area of the rectangle, so you would multiply 7 and 3, which gives you 21, (A=L•W). So now you need to find the area of the triangles, the formula for that is A= 1/2 b•h, so you get 3in for the area of the triangle, but since there are two and they are the exact same triangle you would just combine them, so the area for both triangles is 6in, so then you would need to subtract the 6 from the 21 so that you can find the area of the shape, and your final answer would be 15in(squared). hopefully you understand

Which value of f makes 3f+5=32 a true statement?<br> a. f=6 <br> b. f=8 <br> c. f=9<br> d. f=12
DIA [1.3K]

We just need to solve the equation in order to find the value.

3f+5=32

So we subtract 5 from both sides of the euqation and get

3f=27

Now we divide by 3 on both sides and get

f=9

So the answer is C.


Hope this helps!
