If u use the app photomath it will give u answer with the steps too
Answer:
B
Step-by-step explanation:
A rational number can be expressed in the form
← where a and b are integers
From the set
3 is rational as it can be expressed as
and = 3 ← rational
, and ← are irrational numbers
Thus there are 2 rational numbers out of the 5 given, thus
P( rational ) = → B
Answer:
The cup can hold 235.5 cubic cm of popcorn.
Step-by-step explanation:
A cone shaped popcorn cup has a radius of 5 cm and a height of 9 cm.
Use 3.14 as an approximation for pi.
Now, to find cubic cm of popcorn the cup can hold.
Radius (r)= 5 cm
Height (h)= 9 cm
= 3.14 (as per question).
So, to get the cubic cm of popcorn the cup can hold we put formula of volume:
Volume= r h 3
Volume= 3.14 x 5 × 93
Volume= 3x14 x 25 x 3
Volume= 235.5 cubic cm.
Answer:
x=8
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the base and h is the height
16 = 1/2 (4) x
16 =2x
Divide each side by 2
16/2 = 2x/2
8 =x
The height is 8 units
Answer:
49.81
Step-by-step explanation:
the formula I used is distance=
Lets say we are finding the distance from c to y
c=(-6,9)
y=(5,9)
cy=
cy=
cy=
cy=
cy=11
And you can find the distance between y and i, i and d, d and o, o and c, using the same formula.
After solving the distance of all I got
yi=16.55294536
id=1
do=9.219544457
oc=12.04159458
After you add them all up you get 49.8140844 which rounded to the nearest hundredth is 48.81.
Thank you and I hope that is helpful.
