Answer:
The maximum number of toys you can afford to buy is 40
Step-by-step explanation:
Let
x -----> the number of toys
we have the compound inequality
Divide into two inequalities
-----> inequality A
----> inequality B
<em>Solve the inequality A</em>
Divide by 11 both sides
Rewrite
<em>Solve the inequality B</em>
Divide by 11 both sides
The solution for x is the interval ----> [13,40}
Remember that the number of toys must be a whole number
The domain is all whole numbers greater than or equal to 13 toys and less than or equal to 40 toys
therefore
The maximum number of toys you can afford to buy is 40
Answer:
Step-by-step explanation:
16v/6v=16/6=8/3
10/7=1 3/7
Answer:
The figure will change by a factor of 2.25.
Step-by-step explanation:
When the lengths (1-dimensional) change by a factor 1.5 (the definition of <em>dilating </em>a figure), the area (2-dimensional) will change by a factor 1.5 to the power of the quotient of the values of the dimensions, which is 2/1 = 2. So the area will change by a factor of 1.5^2 = 2.25.
Answer:
X=2.5
Step-by-step explanation:
4+6+4+7+X+(X+1)+8+2/8=5
31+X+(X+1)/8=5
40=31+X+(X+1)
9=X^2+X
X=2.5
Answer:
9.434 X 10^66
Step-by-step explanation:
2.34 X 10^65 + 9.2 X 10^66 (First, you have to manipulate the exponents to bring them to the same index, i.e. the same power)
We can say that 2.34 X 10^65 = 0.234 X 10^66
Now that the indexes are equivalent, we can proceed to add the two bases together.
0.234 X 10^66 + 9.2 X 10^66
= (0.234 + 9.2) X 10^66
= 9.434 X 10^66
