Complete the inequality statement with the symbol that makes it true.
1.67 ___ 16.7
>
<
=
Answer:
The symbol in the blank space would be '<'
Step-by-step explanation:
Since, in inequality,
'>' = greater than,
'<' = less than,
'≥' = greater than equal to,
'≤' = less than equal to,
Now, 1.67 × 10 = 16.7
⇒ 16.7 is 10 times of 1.67,
That is,
1.67 is less than 16.7
⇒ 1.67 < 16.7
Hence, THIRD option is correct.

Step-by-step explanation:
Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have already been declared, use a do...while loop to compute the sum of the cubes of the first n whole numbers, and store this value in total. thus if n equals 4, your code should put 1*1*1 + 2*2*2 + 3*3*3 + 4*4*4 into total. use no variables other than n, k, and total.
If a memory cell whose address is 5 contains the value 8, what is the difference between writing the value 5 into cell number 6 and moving the contents of cell number 5 into cell number 6?
The required difference is value 5 is put in cell 6 and in the second case value of cell 5 is transferred to cell number 6.
Given that,
If a memory cell whose address is 5 contains the value 8, what is the difference between writing the value 5 into cell number 6 and moving the contents of cell number 5 into cell number 6 is to specify.
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is a dependent variable.
Here,
If a memory cell whose address is 5 contains the value 8
implies at cell number 5 the entry is 8
Similarly,
writing the value 5 into cell number 6
While in the case of moving the contents of cell number 5 into cell number 6, Implies 8 is transferred to cell number 6.
Thus, the required difference is value 5 is put in cell 6, and in the second case value of cell 5 is transferred to cell number 6.

divide -2x^3-5x^2+4x+2 by x+2
Final answer:
The detailed answer explains how to divide a polynomial by another using long division method.
Explanation:
To divide -2x³-5x²+4x+2 by x+2, we will perform polynomial long division:
-2x³-5x²+4x+2 / x+2
Start by dividing the leading terms: -2x³ / x = -2x². Multiply x+2 by -2x² to get -2x³-4x². Subtract this from -2x³-5x² to get x². Bring down the 4x next. Continue the process and you will get a quotient of -2x²+x-2 with a remainder of 6.

he value of an autographed baseball from 2017 is $300. The value of the baseball exponentially increases by 5% each year after 2017. Write a one-variable inequality that could be used to solve for the number of years, x, it would take for the baseball to be worth at least $650. Do not use any dollar signs in the inequality. Write the inequality in standard form.
Answer:
[tex]300(1.05)^x\geq 650[/tex]
Step-by-step explanation:
Since, the initial value of the basketball = $ 300
Annual rate of interest = 5 %
Let the basket ball after x years is worth at least $ 650,
⇒ The cost of basketball after x years ≥ 650
[tex]\implies 300(1+\frac{5}{100})^x\geq 650[/tex]
[tex]\implies 300(1+0.05)^x\geq 650[/tex]
[tex]\implies 300(1.05)^x \geq 650[/tex]

Find ONLY the areas of the polygons
11.
area for lower left = 52*62 = 3224
area for upper right = 68*54 = 3672
total area = 3224 + 3672 = 6896 square yards
12.
area of upper left = 57-69 = 3933
area of lower right = 24*37 = 888
total area = 3933 +888 = 4821 square feet

Alvin’s age is two times Elga’s age. The sum of their age is 60. What is Elga’s age?
x = Elgas age
2x = Alvins age
x +2x = 60
3x =60
x = 60/3 = 20
Elga is 20 years old
Final answer:
By setting Elga's age as x and establishing an equation based on the given relationship and sum of their ages, we calculated Elga's age to be 20 years old.
Explanation:
To determine Elga's age, we will use the information given:
1. Alvin's age is two times Elga's age.
2. The sum of their ages is 60.
Let's define Elga's age as x. Then, Alvin's age would be 2x since it is two times Elga's age. The sum of their ages can be written as the following equation:
x + 2x = 60
This simplifies to 3x = 60. To find Elga's age, we divide both sides by 3:
3x / 3 = 60 / 3
x = 20
Therefore, Elga's age is 20 years old.

The perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is 2l + 2w = 16, where lrepresents the length of the rectangle and w represents the width of the rectangle. Which value is possible for the length of the rectangle?
It is basically a trick question. Firstly we have to ficus on the given formula to get to the answer for this question.
2l + 2w = 16
2(l + w) = 16
l + w = 8
l = 8 - w
Mow w cannot be less than 1. So the length of the rectangle cannot be more than 7. So we can conclude that 7 inches is the correct option or the first option is the correct option among the given options.
Hope this helped!!!!!
