The answer is choice A- 68
Answer:
4. C
5. B
Step-by-step explanation:
4. Circumference = diameter * pi
pi is approximately 3.14
Diameter = 2*radius
Diameter = 2*8 = 16
Circumference = 3.14 (16), so the answer is C.
5. The question asking asking for the surface of the toy box.
Surface area of a cube = 6*the area of one face of the cube = 6 (edge * edge)
Substitute the edge with 2
Surface area of the toy box = 6(2*2) = 6(4) = 24
Surface area is 24 feet squared, so the answer is B
Hope this helps :)
Have an awesome day!!
Given:
In a two-digit number, the tens digit is 5 less than the units digit.
The number itself is five more than three times the sum of its digits.
To find:
The number.
Solution:
Let the two digit number is ab. So,
Tens digit is 5 less than the units digit.
...(i)
The number itself is five more than three times the sum of its digits.
...(ii)
Using (i) and (ii), we get
Putting b=8 in (i), we get
Therefore, the required number is 38.
Answer:
b) y-3x = 1
c) 3x+1 = y
Step-by-step explanation:
I think you forgot to write a little part of the question. If your complete statment with this condition, i have the answer.
"Kevin said that if you triple his age the result will be 1 less than his mother age. Which of any of these Equation shows the relationship between Kevin's age x and his mothers age Y choose all that are correct
a) 3x-y=1
b) y-3x=1
c) 3x+1=Y
d) 3x=1-y"
you can write "the triple of this ages" as: 3x. and the result is y-1. That is:
3x = y-1
That equation can be rewrite as:
1. Passing -1 to the other side as +1 you will have: 3x+1=y. That is option c).
2. From last point 3x+1=y. Passing 3x to the other side as -3x you will have: y-3x=1. That is option b).
