Answer:
(C) 1.75 in
Step-by-step explanation:
It give you a clue in the question that the height increases by the same amount each week. This means that if you add 0.25 you will get a constant answer. What I mean by constant is this :-
0.25 + 0.25 = 0.5 in
I can also do it by multiplying it by 2.
2 × 0.25 = 0.5 in
If you add 0.25 every time or if you multiply 0.25 by the number of weeks you will get your answer same. So,
7 × 0.25 = 1.75 in
Hope this helps, thank you !!
Answer:
63
Step-by-step explanation:
A composite number is a whole number. It can be defined as a number that is divisible by 1, itself and other factors. This means a composite number has two or more factors. A prime number cannot be a composite number.
The seven smallest composite numbers are:
4, 6, 8, 9, 10, 14, 16,
Their total sum = 4 + 6 + 8 + 9 + 10 + 14 + 16 = 63
Therefore, the sum of the seven smallest composite numbers which cannot be determined to be composite simply by using the divisibility rules (for 2,3,4,5,6,8,9 or 10) is 63.
Given:
A grandfather is 9 times older than his granddaughter.
In 8 years the grandfather will be 5 times older than his granddaughter.
To find:
The present age of grandfather and granddaughter.
Solution:
Let x be the present age of granddaughter.
Then, present age of grandfather = 9x
After 8 years,
Age of granddaughter = x+8
Age of grandfather = 9x+8
In 8 years the grandfather will be 5 times older than his granddaughter.
Isolate variable terms.
Divide both sides by 4.
Now,
Present age of granddaughter = 8
Present age of grandfather = 9(8) = 72
Therefore, the present age of granddaughter is 8 years and present age of grandfather is 72 years.
we are given
Since, we have to solve this inequality
so, we will isolate x on anyone side
step-1:
Multiply both sides by 3/2
step-2:
Distribute negative sign
step-3:
Subtract both sides by 1/2
step-4:
Subtract both sides by (3/10)x
step-5:
Multiply by sides by -10/23
now, we can simplify it
now, we can write in interval notation as
