an equation that is true for every value of the variable is a ___

Answers

An identical equation is a literal equation that is true for every value of the variable, e.g., the equation (x+1)2=x2+2x+1. A conditional equation (usually referred to simply as an equation) is a literal equation that is not true for all values of the variable, e.g., only the value 2 for x makes true the equation x+3=5.

Trisha spins a spinner. the pointer lands on three prime numbers .she says the sum is less than 12.which could be the number

Answers

The answer is 2, 3, and 5

The sum of the first three prime numbers less than 12 is 2, 3, and 5.

What is a Prime number?

A prime number is a positive integer having exactly two factors that are 1 and number itself. Any number that does not follow this is termed a composite number.

Given

Trisha spins a spinner. the pointer lands on three prime numbers.

She says the sum is less than 12.

How to find the prime number?

The prime numbers are as follows,

2, 3, 5, 7, 11..so on

So the sum of the first three prime numbers will be

2 + 3 + 5 = 10

Hence, the sum of the first three prime numbers less than 12 is 2, 3, and 5.

Since the slope of a vertical line is undefined, is it possible for vertical lines to be parallel.(Explain)

Answers

Yes the slope of a vertical line is parallel.

Parallel lines never intersect each other.

Y-axis is a vertical axis cartesian coordinate plane.

All vertical lines would be parallel to y-axis.

Because all vertical lines would have same slope, that is undefined slope.

Therefore, all vertical lines would be parallel lines.

So, we can finally say that it is possible for vertical lines to be parallel.

Julie is digging a square area in her backyard a for a vegtable garden. If the area is 52 square feet, what is the approximate length of one of her garden?
(a) 6 feet
(b) 7 feet
(c) 8 feet
(d) 9 feet

Answers

Answer:

The correct option will be:   (b) 7 feet.

Step-by-step explanation:

Suppose, the length of the garden is  [tex]x[/tex] feet.

As the shape of the garden is like a square, then the area of the garden will be: [tex](length)^2 = x^2[/tex] feet²

Given that, the area is 52 square feet. So, the equation will be.......

[tex]x^2= 52\\ \\ x=\sqrt{52} = 7.211.... \approx 7[/tex]

So, the approximate length of the garden will be 7 feet.

Calculate the slope of the line that passes through the labeled points on the graph.

Answers

m=(Y2-Y1)/(X2-X1)


(1.) m=(2-(-1))/(-2-3) = 3/-5 = -3/5

(2.) m=(-2-1)/(-3-2) = -3/-5 = 3/5  

(3.) m=Infinity (equation: x=-2)



The slopes of the lines passing through the given points are: 1. [tex]\((-2,2)\)[/tex] and [tex]\((3,-1)\)[/tex]: [tex]\(m = -\frac{3}{5}\)[/tex]. 2. [tex]\((-3,-2)\)[/tex] and [tex]\((2,1)\)[/tex]: [tex]\(m = \frac{3}{5}\)[/tex]. 3. [tex]\((-2,-2)\)[/tex] and [tex]\((-2,3)\)[/tex]: The slope is undefined (vertical line).

To calculate the slope m of a line given two points [tex]\((x_1, y_1)\)[/tex] and [tex]\((x_2, y_2)\)[/tex], you can use the formula:

[tex]\[m = \frac{y_2 - y_1}{x_2 - x_1}\][/tex]

Let's apply this formula to the given points:

1. For points (-2,2) and (3,-1):

[tex]\[m = \frac{-1 - 2}{3 - (-2)} = \frac{-3}{5}\][/tex]

2. For points (-3,-2) and (2,1):

[tex]\[m = \frac{1 - (-2)}{2 - (-3)} = \frac{3}{5}\][/tex]

3. For points (-2,-2) and (-2,3):

[tex]\[m = \frac{3 - (-2)}{(-2) - (-2)} = \frac{5}{0}\][/tex]

The slope for the third set of points is undefined because the denominator becomes zero, indicating a vertical line. The first two sets of points have slopes of [tex]\(-\frac{3}{5}\)[/tex] and [tex]\(\frac{3}{5}\)[/tex] respectively.

Tina bought two pairs of regular socks and one pair of long fleece socks .The fleece socks cost $12.If the final price ,including 5% sales tax ,was $30.45,what was the price of each pair of regular socks?

Answers

So first we need to get rid of that naughty sales tax so we need to divide 30.45 by 1.05 since 30.45 is 105% of the pre-tax price. We get the answer of 29 and subtract 12 from 29 since the long fleece socks cost 12 bucks and we get 17 dollars. Since there are 2 pairs of regular songs we divide 17 by 2 and get 8.5

So the regular socks cost $8.50

Checking work 8.5*2=17
12+17=29
1.05*29=30.45

A 13.9 gallon gas tank is 4/5 full. How many gallons will it take to fill the tank?

Answers

It will take 2.78 gallons to fill the remainder of the tank.

13.9 * 4/5 = 11.12    - 11.12 is the amount of gas already in the tank.

13.9 - 11.12 = 2.78    - So, subtract 11.12 from 13.9 and you get your answer.

G.o has 3 orange picks for every two green. If there are 25 picks in all, how many picks are orange

Answers

15 picks are orange....

Answer:

15 orange picks.

Step-by-step explanation:

Let x represent the number of orange picks.

We have been given that G.o has 3 orange picks for every two green. We are asked to find the number of orange picks, if there are 25 picks in all.

Since there are 3 orange picks for every two green. so there will be 3 orange picks for all 5 (3+2) picks.

We will use proportions to solve our given problem.

[tex]\frac{x}{25}=\frac{3}{5}[/tex]

Upon multiplying both sides of our equation by 25, we will get:

[tex]\frac{x}{25}*25=\frac{3}{5}*25[/tex]

[tex]x=3*5[/tex]

[tex]x=15[/tex]

Therefore, there are 15 orange picks for all 25 picks.

Answer:

The answer is B x^3

Step-by-step explanation: I just took the FLVS exam and this was the correct answer

x3 is the Greatest Common Factor of x6 and x3.

How do you find the greatest common factor?

The greatest common factor is the greatest factor that divides both numbers. To find the greatest common factor, first list the prime factors of each number. 18 and 24 shares one 2 and one 3 in common. We multiply them to get the GCF, so 2 * 3 = 6 is the GCF of 18 and 24.

What is the GCF of 4 and 6?

The largest number of all those common factors is known as the greatest common factor (GCF). Here, 2 is the largest number found in both factors. Hence, the GCF of 4 and 6 is 2.

An engineer designing a ramp in a football stadium was told to keep the slope to a ratio of 1:10. The ramp height is 25 ft. What is the Ideal Mechanical Advantage of the ramp? (Its 10.05, but how do I solve it?)

Answers

we know that

To calculate the ideal mechanical advantage for an inclined plane, divide the length of the incline by the height of the incline

Step 1

Find the horizontal distance of the ramp

we know that

the ramp has a slope of [tex]1:10[/tex]

so

by proportion

[tex]\frac{1}{10} \frac{height}{long} =\frac{25}{x} \frac{height}{long} \\ \\x=25*10 \\ \\ x=250\ ft[/tex]

Step 2

Find the length of the incline of the ramp

Applying the Pythagorean Theorem

[tex]incline^{2}=height^{2}+horizontal^{2}[/tex]

substitute the values

[tex]incline^{2}=25^{2}+250^{2}[/tex]

[tex]incline^{2}=63,125[/tex]

[tex]incline=251.25\ ft[/tex]

Step 3

Find the ideal mechanical advantage

[tex]Ideal\ Mechanical\ Advantage=\frac{incline}{height}[/tex]

substitute the values

[tex]Ideal\ Mechanical\ Advantage=\frac{251.25}{25}=10.05[/tex]

therefore

the answer is

the Ideal Mechanical Advantage of the ramp is [tex]10.05[/tex]

5x+2(x+9)=x+4x+43
How do you solve this?

Answers

x = 25/2


this is your answer

Step 1. Simplify x + 4x + 43 to 5x + 43

5x + 2(x + 9) = 5x + 43

Step 2. Cancel 5x on both sides

2(x + 9) = 43

Step 3. Divide both side by 2

x + 9 = 43/2

Step 4. Subtract 9 from both sides

x = 43/2 - 9

Step 5. Simplify 43/2 - 9 to 25/2

x = 25/2
