Find the value of 14+5•3-3^2. Then change two operation signs so that the value of the expression is 8

Answer:

8

Step-by-step explanation:

think about this: which number has the bigger distance from 0 on a number line.

-4  -3  -2  -1  0  1  2  3  4  5  6  7  8

You can see the distance between -4 and 8. Because 8 is eight spaces away from zero, and -4 is 4 spaces away from zero, we can see that 8 is bigger

The 8 is greater than -4. The difference between the two numbers is 12, and 8 is a positive number, while -4 is a negative number, solidifying that 8 is the larger value.

To compare the numbers -4 and 8, we can use the number line or basic numerical comparison. On the number line, -4 is to the left of 8, indicating that 8 is greater. Additionally, we can verify this by subtracting -4 from 8, which gives us 12 (8 - (-4) = 12). Since 12 is positive, 8 is indeed greater than -4.

In numerical comparison, when a positive number is compared to a negative number, the positive number is always greater. This is because negative numbers are "less than" zero, and positive numbers are "greater than" zero.

In conclusion, 8 is greater than -4. The difference between the two numbers is 12, and 8 is a positive number, while -4 is a negative number, solidifying that 8 is the larger value.

Answer:

[tex]\Large \boxed{\mathrm{Option \ B}}[/tex]

Step-by-step explanation:

The equation is in the form ax² + bx + c = 0.

x² - c = 0

1x² + 0x + -c = 0

Where : a = 1, b = 0, and c = -c

c > 0

The quadratic equation can always be factored if c is a square number

c can be a square number and the quadratic equation can be solved by using the difference of two squares formula.

x is squared so it can be solved by isolating x on one side by adding c to both sides and using the square root property.

Answer:

[tex]\huge\boxed{Option \ B}[/tex]

Step-by-step explanation:

[tex]x^2 - c = 0[/tex]

This equation is in a quadratic form since:

=> It has the highest power of x as 2. Those equations are quadratic equations in which the highest power of x is 2.

=> However, Those quadratic equation in which b = 0 , and they are like either [tex]ax^2 + c = 0 \ OR \ ax^2-c = 0[/tex], They are called pure quadratic equation.

So, [tex]x^2 - c = 0[/tex] is a quadratic equation.

Each ticket cost 4.05

Step-by-step explanation:

Start by finding what is 60% of 13.50 = 0.6 * 13.50 = 8.10

Answer:

1 inch represents 1 mile

66330 inches represent 1 mile

Convert to feet = 5280 feet for every mile

So if the map shows y = 1 1/4  then this means 1 1/4 miles

which would make the decimal of y = 1.25

which makes x = 5280 x 1.25 = 6600

We can just convert to decimalization the ' length of y in inches' and multiply by 5280 to find our answer.

= y * x   = (1 .) + additional)  * 1 * 5280

Not forgetting the above decimal if under 2 inches.

Or in any measure including if over 2 inches we can use

= measure of y  * 5280  = (  ) answer

If [tex]1[/tex] inch on a map represents [tex]y[/tex] miles, then the miles represented by [tex]x[/tex] feet on the same map will be [tex]12[/tex] miles.

A map is a visual representation of an entire area or a part of an area, typically represented on a flat surface.

Mile is a measure of length, in one mile there 1.6 kilometers.

We  have,

[tex]1[/tex] inch [tex]=y[/tex] miles

Then,

[tex]x[/tex]  feet will represent miles on map will be as

We know that,

[tex]1[/tex] feet [tex]=12[/tex] inch

So,

According to question,

Miles represented by [tex]x[/tex] feet [tex]=12y[/tex] miles

Because according to the above given statement we came to know that in [tex]1[/tex] feet there are [tex]12[/tex] inches.

Hence, we can say that if [tex]1[/tex] inch on a map represents [tex]y[/tex] miles, then the miles represented by [tex]x[/tex] feet on the same map will be [tex]12[/tex] miles.

Answer: About 175 homeruns

Step-by-step explanation:

For every 135 games played, he hit 22 home runs, which makes an average of 1 home run every 6.136 games. Take that number and divide 1075 by it.

1075 / 6.136 = about 175.

Carlos Gonzales hits 175 runs in his total of 1075 games in his career.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Number of games played by Carlos Gonzales = 135.

And runs hit by Carlos Gonzales = 22 runs.

To find the runs hit by Carlos Gonzales in 1075 games,

Use ratio property,

In 135 games = 22 runs hit,

in 1 game = 22 / 135 runs hit,

In 1075 games = (22/135)x1075 = 175.18 = 175 (approx)

The runs hit by Carlos Gonzales in 1075 games is 175.

Answer:

x = sqrt(17)

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2

Let the unknown side be x

8^2 + x^2 = 9^2

64 + x^2 = 81

Subtract 64 from each side

x^2 = 81-64

x^2 =17

Taking the square root of each side

x = sqrt(17)

Answer:

x = √17

Step-by-step explanation:

Your question have a right triangle.

So, we could use the Pythagorean Theorem.

Pythagorean Theorem is a² + b² = c².

So, 8² + n² = 9².

8² is 64, and 9² is 81.

So, 'n' is 81 - 64.

Let's see... 81 - 64 is 17.

So, It is √17.

Because when you use the Pythagorean Theorem, it is 8² + (√17)² = 9².

Otherwise, 64 +  (√17)² = 81.

And, √17 is 4.12 when rounding to a hundredth.

Answer:

D. 22.5

Step-by-step explanation:

By the property of intersecting tangent and secant outside of the circle, we have:

x° = 1/2[(4x+5)° - 50°]

2x° = [(4x+5)° - 50°]

2x° = (4x-45)°

2x = 4x - 45

45 = 4x - 2x

45 = 2x

x = 45/2

x = 22.5

Answer:

2gramm/millimeters

Step-by-step explanation:

From the question we were given 5

gram ball with a volume of 2.5 milliliters.

Then What is the density of the ball?

Density of a substance is the mass of the substance per it's unit volume

It can be expressed below as

Density= mass/ volume

Mass= 5gram

Volume= 2.5millimetre

Then substitute we have

Density=5/2.5

=2g/mm

Therefore, density of the ball is 2gramm/millimeters

Answer:

Coordinates of the point P are [tex](-\frac{29}{7},-1)[/tex]

Step-by-step explanation:

If a point P(x, y) divides the line AB into the ratio of m : n, coordinates of this point will be,

x = [tex]\frac{mx_2+nx_1}{m+n}[/tex]

y = [tex]\frac{my_2+ny_1}{m+n}[/tex]

In the given question m : n = 3 : 4

And the coordinates of A and B are (-5, -4) and (-3, 3) respectively.

x = [tex]\frac{3(-3)+4(-5)}{3+4}[/tex]

x = -[tex]\frac{29}{7}[/tex]

y = [tex]\frac{3(3)+4(-4)}{3+4}[/tex]

y = -1

Therefore, coordinates of the given point P are [tex](\frac{29}{7},-1)[/tex].

slope = 2/-6 = -1/3

distance (-1,-4) to (0, -4.63)

√(-1 - 0)² + (-4 - -4.63...)² = √1.4 = 1.18

6.32 - 1.18 = 5.14

1.18 : 5.14

Answer:

[tex]0=\frac{-1(k)+1(5)}{k+1} \\or~0=-k+5\\or~ k=5\\\therefore ~y-axis~ divides ~A,B~in~the~ratio~5:1\\y=\frac{5(-4)+1(-6)}{5+1} =\frac{-26}{6} =-\frac{13}{3}[/tex]
