Answer:

The third one.

Step-by-step explanation:

The square root of 81 is 9. The closest answer to that is the third one.

Answer:

x is between 80 and 90

Step-by-step explanation:

Square both sides

x= 9^2, so 9*9

x=81

Answer:

The answer is 31/20.

Step-by-step explanation:

First, you have to have both fractions the same denorminator :

[tex] \frac{9}{4} - \frac{7}{10} [/tex]

[tex] \frac{9 \times 5}{4 \times 5} - \frac{7 \times 2}{10 \times 2} [/tex]

[tex] \frac{45}{20} - \frac{14}{20} [/tex]

Next, you have to subtract :

[tex] \frac{45}{20} - \frac{14}{20} [/tex]

[tex] \frac{45 - 14}{20} [/tex]

[tex] \frac{31}{20} [/tex]

Answer:

9/4 - 7/10= 31/20=1 11/20

Step-by-step explanation:

look first for their LCM=20

2 4 10

2 2 5

5 1 5

1 1

then you divide the LCM which is 20by one of the denominator and multiply by the numerator over denominator

20/4*9=45/20

20/10*7=14/20

now both have the same denominator so we just subtract the numerators

45-14/20=31/20

now we have subtracted and our answer is in improper fraction so we need to change to mixed fraction

31/20=1 11/20

Step-by-step explanation:

10-7=3  3-7=-4

Answer:

The equation given above is  sqrt (2x + 1) = 3. First, square both sides of the equation giving, 2x + 1 = 9. Solving for x in this equation gives an answer of x = 4. When we substitute x = 4 to the original equation, the number inside the radical sign is positive. Thus, x = 4 and it is a non-extraneous root.

Answer:

x = [tex]\frac{c+b}{a}[/tex]

Step-by-step explanation:

Given

ax - b = c ( add b to both sides )

ax = c + b ( divide both sides by a )

x = [tex]\frac{c+b}{a}[/tex]

True, all fractions and mixed numbers become decimals that either terminate or repeat. Every fraction can be written as a decimal, either terminating or repeating. To write a fraction as a decimal, divide the numerator by the denominator.

Answer:

Q1:

The red dot is after the ninth line, and the two numbers are [tex]2.182[/tex] and [tex]2.183[/tex].

This means that the number has to be [tex]2.1829391321...[/tex]

Q2:

The red dot is after the third line, and the two numbers are 2 and 3.

This means that the number has to be [tex]2.364125...[/tex]

Q3:

There seems to be an error with this question, as the red dot is after the seventh position. This means that the number should be at least [tex]2.117...[/tex] but there isn't any option so we will skip this.

Q4:

The red dot is after the second line, and the two numbers are [tex]2.18[/tex] and [tex]2.19[/tex].

This means that the number is [tex]2.1823912...[/tex]

The remaining option will be the answer for Q3.

Answer:

[tex]d=\dfrac{V}{bt}[/tex]

Step-by-step explanation:

It is given that,

V = bdt i.e. V is equal to the product of b, d and t

We need to find the formula for d.

Dividing both sides of the given expression by bt

So,

[tex]\dfrac{V}{bt}=\dfrac{bdt}{bt}\\\\d=\dfrac{V}{bt},\ \text{bt in both denominator and numerator cancel out}[/tex]

Hence, [tex]d=\dfrac{V}{bt}[/tex] is the value of d.

Answer:

B

Step-by-step explanation:

The equation c = 100 + 5C represents the cost c of a book bag order depending on the number of bags option (B)  c=5n+100 C is correct.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A company makes a book bag and charges a one-time design fee of $100 and then $5 for each bag made.

C is the number of the book bag.

The fixed cost/one-time design fee = $100

Total cost c = 100 + 5C

Thus, the equation c = 100 + 5C represents the cost c of a book bag order depending on the number of bags option (B)  c=5n+100 C is correct.

The value of 2² + {[1 x (5 - 2)] x 3 using PEDMAS is 13.

To simplify the expression 2² + {[1 x (5 - 2)] x 3}, we will use PEDMAS

First, within the innermost parentheses, we have 5 - 2, which equals 3.

So the expression becomes: 2² + {[1 x 3] x 3}.

Next, we simplify the multiplication within the curly brackets: 1 x 3 equals 3.

= 2² + {3 x 3}.

Now, we evaluate the exponent 2², which means 2 raised to the power of 2. It equals 4.

= 4 + {3 x 3}.

Finally, we multiply within the curly brackets: 3 x 3 equals 9.

= 4 + 9.

Adding 4 and 9, we get the final result: 13.

Therefore, 2² + {[1 x (5 - 2)] x 3} equals 13.

Answer:

37 and 38.

Step-by-step explanation:

Let the smaller integer be x.

Thus, the larger integer is (x+1) since it is consecutive.

[tex]x+(x+1)=75[/tex]

[tex]2x+1=75[/tex]

Subtract both sides by 1:

[tex]2x+1-1=75-1[/tex]

[tex]2x=74[/tex]

Divide both sides by 2:

[tex]\frac{2x}{2}=\frac{74}{2}[/tex]

[tex]x=37[/tex]

To find the other number, simply add 1 to 37 to get 38.

Answer:

37 and 38

Step-by-step explanation:

Let the two consecutive integers be x and x+1

According to the question,

sum of the two consecutive integers is 75

Therefore,

x +(x+1)= 75

=>2x+1=75

=>2x=75-1

=>2x=74

=>x=74/2

=>x=37

So, the two numbers are 37 and (37+1)
