It would be an over estimate the answer should be 4 3/10 x 7 = 30 1/10 or 4 3/10 x 5 = 20 1/2 hope this helps
It will be an underestimate the answer is 43 I hoped that helped?
What is the exact area of a circle with a diameter of 25 pi m?A. 25 pi m²
B. 50 pi m²
C.156.25 pi m²
D. 625 pi m²
Answers
The rule to figuring out the area of a circle is A=r^2*pi.
So since the radius is half of the diameter you will ne to cut 25 in half. Which equals 12.5. OK so now we need to multiply 12.5 by 12.5 which equals 156.25.
First try to break up your values as perfect squares we know that 2x 25 = 50 So putting them under the radical to square root is ✔️25 x ✔️2 is the same as ✔️50, but square of 25 is 5 so it comes outside the radical and you are left with 5✔️2. Sorry I dont have or know where myvsquare root sign is on my iphone keypad. The answer is A.?
I need help with this Two-step equation
18-4x= -2
Can anyone help?
Answers
- - Star to simplify both sides of the equation.
- - Now you have top subtract 18 from both sides.
- - Solve:
- - And divide both sides by -4.
- - Solve:
first u would take the 18 and - it on both sides 18 - 18 - 4x = -2 - 18 which would be -4x = -20 then u would divide 4 on bothe sides -4x/4 = -20/4 which would give u - x = - 5 this is the answer for the negative x for positive u would flip the answer so x = 5 which then = 4 x=5 is ur answer hope this helps or u understand wat im sayin
The measure of an angle is 176.9°. What is the measure of a supplementary angle?
Answers
Here, it is easier to add to 176.9 to get to 180 degrees. First, make it a whole number by adding 0.1, which gives you 177. Then it takes 3 degrees to get to 180, so the answer is 3.1 degrees.
Hope this helps.
HOW MANY HALF METERS TOGETHER MEASURE 4 1/2 AND HOW DO YOU DO IT
Answers
2 halves (1/2) make a whole (1/1) and there are 4 wholes and 1 half so 2 times 4=8 8+1=9 so nine halves
4 1/2 = 4.5 half a meter = 0.5 = 1/2 then divide 4.5 by 0.5 4.5/0.5 when dividing by 0.5 or 1/2 it is the same as multiplying by 2 so.. 4.5 x 2 = 9 so 9 half meters measure 4 1/2
