Answer: 4√2/13
Step-by-step explanation: add the 3 and 5 together and simplify your radical expression. keep the 13 as the denominator because you cannot divide the simplified radical into that.
Answer:
I am led to believe the answers are 4 and 1
Step-by-step explanation:
I don't think its answer 2 because thou are radios and their isn't any fractions in it
I solved answer 4 it came as a fraction
Okay i looked at 1 and i did all of them they all came out as a decimal so i think that's another one
answer 3 you can't divide by 0 so i don't think so
Answer:
15:21 = 5:7
Step-by-step explanation:
21/7 = 3
5 x 3 = 15
Answer:
Solution : Third Option
Step-by-step explanation:
The first step here is to make all the signs uniform. As you can see the third inequality has a less than sign, which we can change to a greater than sign by dividing negative one on either side, making the inequality y > - 7.

Now take a look at the third option. Of course the y - coordinate, 3, is greater than - 7, so it meets the third requirement ( y > - 7 ). At the same time 3 > 1( 2 ) > 2, and hence it meets the second requirement as well. 3 > - 3( 1 ) + 4 > - 3 + 4 > 1, meeting the first requirement.
Therefore, the third option is a solution to the system.
The surface area of cylinder is 8.625
, if the cylinder has 5 centimeters high and 1.5 cm of diameter.
Step-by-step explanation:
The given is,
Cylinder has a 5 centimeters height
Diameter of the cylinder is 1.5 centimeters
Step:1
Formula for the surface area of cylinder is,
......................................(1)
Where,
h - Height of cylinder
r - Radius of cylinder
From the values of h and r,

= 
r = 0.75 cm
From the formula,
= ( 2 ×
× 0.75 × 5 ) + ( 2 ×
×
)
= ( 7.5
) + ( 1.125
)
A = 8.625

Result:
The surface area of cylinder is 8.625
, if the cylinder has 5 centimeters high and 1.5 cm of diameter.
