Select one:
a. ±7
b. 7
c. −7
d. 24.5
The negative square root of 49 is -7.
Option C is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
2² + 4 i s an expression.
3² + 4³ + 3³ is an expression.
3 + 4 x 5 + 4³ is an expression.
We have,
-√49
7 x 7 = 49
Make an exponent of base 7.
7² = 49
So,
-√49
= -√7²
Square root and exponent 2 get canceled.
= -7
Thus,
The negative square root of 49 is -7.

The quotient of two consecutive positive integers is 1.02. What is the sum of these two integers?
If quotient of two consecutive positive integers is 1.02 then the sum of the two integers is 101.
What is Number system?A number system is defined as a system of writing to express numbers.
Let x be the smaller of the two consecutive positive integers. Then, the next consecutive integer is x + 1.
According to the problem, the quotient of these two consecutive integers is 1.02. In other words:
(x + 1) / x = 1.02
Multiplying both sides by x, we get:
x + 1 = 1.02x
Subtracting x from both sides, we get:
1 = 0.02x
Dividing both sides by 0.02, we get:
x = 50
Therefore, the two consecutive positive integers are 50 and 51, and their sum is:
50 + 51 = 101
Therefore, if quotient of two consecutive positive integers is 1.02 then the sum of the two integers is 101.

What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.
Given:
The expressions are equivalent,
Expressions that function identically despite having distinct appearances are called equivalent expressions. If two algebraic expressions are equivalent, then when we enter the same value(s) for the variable, the two expressions have the same value (s).
As you can see in the options 2 - x because this will equal (-x +2) or 2 + (-x)
Thus, the expression which is not equivalent is 2 - x.

Can you give a reason why a calculator shows 2/3 equal to 0.666666667
The division of 2 by 3 will give an answer which does not terminate so the calculator rounds the answer.
Given division problem is 2 by 3.
Here it clearly cannot be divided evenly.
The quotient is 0.6666....
We know about the rounding of numbers.
When the next number is greater than 5, the preceding number will add 1.
Here each number is 6, which is greater than 5.
So any number can be written as 7 and then stop the answer.
So this can be written as :
0.7, 0.67, 0.667,...
Hence the calculator shows 7 after certain digits.

Using the distributive property, which expression is equivalent to 5(32)? 5(3+2) 32(5+2) 5*30 + 2*30 5(30+2)
The given expression 5(32) using the distributive property will be 5(30+2). The correct option is E.
What is Distributive property?The distributive property of multiplication is that when two numbers are added such as (a+b) and multiplied by a third number such as x, then the result will be the sum of the multiplication of the third number with the first number (xa) and the third number with the second number (xb).
x(a+b) = xa + xb,
The given expression using the distributive property can be written as,
5(32) = 5(30 + 2)
Hence, the given expression 5(32) using the distributive property will be 5(30+2).

you want to buy a bouquet of yellow roses and baby's breath for $16.the baby's breath costs $3.50 per bunch,and the roses cost $2.50 each.you want one bunch of baby's breath and some roses for your bouquet.how many roses can you buy?
After subtracting the cost of one bunch of baby's breath ($3.50) from the total budget ($16), you have $12.50 left for the roses. Since each rose costs $2.50, you can buy 5 roses to complete your bouquet within the budget.
To calculate the number of roses that can be bought, first, we need to subtract the cost of one bunch of baby's breath from the total budget for the bouquet. The cost of one bunch of baby's breath is $3.50. With a total budget of $16, we subtract the cost of baby's breath to see how much is left for the roses:
$16.00 - $3.50 = $12.50
Since each rose costs $2.50, we will divide the remaining budget by the cost of each rose to find out the number of roses that can be purchased:
$12.50 / $2.50 = 5 roses
Therefore, you can buy 5 roses along with one bunch of baby's breath to make up your $16 bouquet.
