i need help with this math please
Answer:
question 1: it is between 8 and 9. question 2: option B.
Step-by-step explanation:
1. since the closest value that IS a squarable number is 64, the square root of 64 is 8. because 66 is greater than 64, we can estimate that the square root of 66 is between 8 and 9.
2. to solve this, we can take the square root of the numbers to begin.
the square root of 25 is 5 (because 5x5=25)
the square root of 16 is 4
20 is actually not squarable, so we can estimate that it is a little greater 4.
the answer would be √16, √20, 4.85, √25
it would be option b.
hope this helps!! :))

D. 132 in^2
ty
Answer:
1. 14.40m
2. 128cm²
3. i can barley see the second picture but i believe the answer is 123 inches squared. (i dont know if i did this one right, I'm a I D I O T.)
Step-by-step explanation:
1. You would multiply 6 by 2.4 which equals 14.40.
2. you would multiply all sides (that are available.) then subtract the non-shaded square which give you a total of 128cm².
3. you would multiply all sides, 24 x 24 x 36 = 20.736, (you add the decimal for farther progress.) round by the nearest tenth you get 207 then add the right triangle area and you get 123 inches squared.
I HOPE YOU GET THIS RIGHT! HAPPY EARLY VALENTINES DAY!

A rotating lawn sprinkler sprays water in a circular area of grass, as shown in the picture. The diameter of the circular area of grass is 16 ft. Which measurement is closest to the area in square feet that this sprinkler sprays with water? And my teacher said to use use C=pi x diameter, And PLEASE I need help I'm failing and I want my mom to be proud of me.
Answer:
15.24
Step-by-step explanation:
C=pi x diameter is what i use, you just have to multiply the diameter by pi or 3.14 and that is your answer! So I multiplied 16 and 3.14 and i got 15.24
I hope this helps :)

Answer: The slope is -5. The y-intercept is (0, 4).
Step-by-step explanation:
Slope Intercept Formula: y = mx + b
m = slope
b = y-intercept
y = -5x + 4
Slope = -5
Y-intercept = 4 or (0, 4)

PLEASE HELP! (WILL GIVE BRAINLIEST FOR RIGHT ANSWER)
Answer:
-41.29* 10^-7
Step-by-step explanation:
You would change the order of the numbers by multiplying -4.44 and 9.3 together and multiply 10^-7 and 10^0. Which would now look like this:
(-4.44* 9.3)* (10^-7* 10^0)
-4.44* 9.3= -41.292 and 10^-7* 10^0= 1* 10^-7. So now the equation would look like this:
-41.292* 10^-7
Then round -41.292 to 2 decimal places which would be -41.29.
-41.29* 10^-7
That's the answer. I hope this helps!

Quinn's mom went to the same middle school that Quinn is now attending. The current student population is 817 students. Since Quinn's mom attended, the school has experienced a
57% increase in population. About how many students were enrolled at the school when Quinn's mom attended?
Answer:
520
Step-by-step explanation:
Past number of pupils: p
Increase of 57% = 1.57
Present number of pupils = 817
p x 1.57 = 817
p = 817 divided by 1.57 = 520.382
rounded to the nearest whole number = 520 (this is why the question says "about" how many...)
57 x 817 = 46569
46569 divided by 100 = 465.69
817-465.69 = 351.31
Answer : 351
Explanation : 57 times 817 equals to 46569 and then you divided by 100 . Then it equals to 465.69 . To find out the how many more students were enrolled you have to subtract 465.69 from 817 and then you get 351.31 which you round to 351 .
