Ages of Dan and Cary are 29 and 33 respectively.
<u>Step-by-step explanation:</u>
Step 1:
Form equations out of the given details. Let the age of Dan be x, then age of Cary is x + 4.
In 7 years, sum of their ages = 76
⇒ (x + 7) + (x + 4 + 7) = 76
⇒ 2x + 18 = 76
⇒ 2x = 58
⇒ x = 29
Step 2:
Calculate age of Cary.
⇒ x + 4 = 33

Hi, I hope this helps; I apologize for answering late. I just now completed this lesson, myself! I assure you its right.
Answer:
$210
Step-by-step explanation:
Say you were to write it as a function. F(x)=30<em>x</em>
all you have to do is fill in for <em>x</em>
30 times 7 = 210
If 16.1cm is a radius of circle:
# Area= Pi X R{2}
= 3.141592654 X 16.1 square
= 814.3 cm square
# circumference= Pi X 2 X R
= 3.141592654 X 2 X 16.1
= 101.2 cm
# if 16.1 is a diameter:
#Area= Pi X D/2 square
= 3.141592654 X 16.1 divide by 2 square
= 203.6 cm square
#Circumference= Pi X D
= 3.141592654 X 16.1
=50.6 cm
That's it it. a bit long cuz I dun know what exactly what they given Radius or Diametre.
Given:
Two cubes are rolled together.
To find the probability that the sum of the numbers on the number cubes will equal 4.
Formula
P(A) =
where, A be any event.
x be the number of successful outcomes
y be the total number of outcomes
Now,
If the two cubes are rolled together, total number of outcomes = 36
In total outcomes, the sum of the numbers of cube will be 4 for (1,3),(3,1) and (2,2)
So, the number of successful outcomes = 3
Now,
Putting x=3 and y = 36 we get,
or,
Hence,
The probability that the sum of the numbers on the number cubes will equal 4 is . Option D.
