Answer:
2.4747996 * 10^1
Step-by-step explanation:
When working in scientific notation, (a * 10^b) * (c*10^d)
Multiply a*c then add 10 ^(b+d)
Then check that the product of ac is between 1 and 10, if not then we need to adjust so that it is
(7.93205×10^8) • (3.12×10^-8)
(7.93205) • (3.12) =24.747996
10^(8-8) = 10^0
24.747996 needs to be adjusted to be between 1 and less than 10
we move the decimal 1 to the left so we add 1 to the exponent
2.4747996 * 10^0+1
2.4747996 * 10^1
Answer:
Answer:
The student council made more snow cones per hour than the parent volunteers.
Explanation:
To find the number of snow cones made per hour:
XXX
Divide the number of snow cones made
XXX
by the number of hours spent making snow cones.
Parent volunteers
XXX
Number of snow cones:
120
XXX
Number of hours spent making snow cones:
5
Number of snow cones per hour:
120
÷
5
=
24
Student council
XXX
Number of snow cones:
100
XXX
Number of hours spent making snow cones:
4
Number of snow cones per hour:
100
÷
4
=
25
Since the student council made
25
snow cones per hour and the parent volunteers only made
24
snow cones per hour:
the student council made more snow cones per hour.
Step-by-step explanation:
6/11 = 0.545454..
= 0.55 rounded to nearest hundredth
3(x-4)>= 5x+2
Distributing 3 on x-4
3(x)-3(4)>=5x+2
3x-12>=5x+2
Now we need to move x terms together and the numbers together and for that we subtract 5x to both sides and add 12 to both sides
-2x >=14
Now we need to get rid of -2, and for that we divide both sides by -2 and on dividing by negative number, the sign of inequality change , that is
x<=-7
Answer:
sqrt d = 10
d = (10)^2
d = 100
Part b
x^2 = 144
x = 12 or -12
