Find the product. 526 x 9

Answer:

Slope=2

Step-by-step explanation:

Slope=rise/run

We can start at 2, 3 (you can start anywhere on the line)

Then go to 3, 5 (you can end anywhere on the line)

Rise=2

Run=1

2/1=2

Slope is 2. The uses up there were examples. It doesn't have to be the exact points.

Answer: 256 miles

Step-by-step explanation:

if 1 1/4 inches = 80 miles, then 1/4 inch = 16 miles (there are five 1/4 in 1 1/4 inches, so 80/5 = 16)

there are sixteen 1/4 inches in 4 inches, and we know that each 1/4 inch is equal to 16 miles, so 16*16 = 256

Answer:

x = 39

Step-by-step explanation:

We know that PRQ is a right triangle, so we use the pythagorean theorem to solve the problem. The theorem states that a^2 + b^2 = c^2. Let's assume that the length of RP is c, the length of PQ is a and x is b. We plug the lengths into the equation and solve it:

80^2 + x^2 = 89^2

6400 +x^2 = 7921

x^2 = 1521

x = [tex]\sqrt{1521}[/tex]

x = 39

Answer:

2,4

Step-by-step explanation:

This question is quite simple. First you need to find the factors of 8. Then you need to see which factors of positive 8 can add up to make -6. The factors are -4 and -2. Then expand. Now you have the equation x^2-4x-2x+8. Now group it.

(x^2-4x) +(-2x+8)

Then take out the X from the first group and the -2 from the second. We want the values in the brackets to be the same.

Now you have

x(x-4)-2(x-4)

Take the x and the -2x and make it a group. Now you have (x-4)(x-2)

Set x-4 equal to zero. x-4=0 Now solve it like a regular equation. Add four to both sides. Now you have x=4

Do the same thing with (x-2) and you get x=2

4 and 2 are your solutions

Answer:

x = 4 and x = 2

Step-by-step explanation:

The easiest way to find the roots is by converting the function into its factored form. This can be determined by asking the question:

What two numbers have a product 8 and a sum of -6?

These two values are -4 and -2.

-4 x -2 = 8

-4 + (-2) = -6

These two numbers are used in the factored form of the equation. You can prove the accuracy of the factored form by re-expanding it (multiply all the terms in the first parentheses by the terms in the second parentheses). The factored form looks like this:

(x - 4)(x - 2)

The roots are the values that make the expression equal 0. This can be done by setting each parentheses equal to 0 and solving for "x".

x - 4 = 0                              x - 2 = 0

x = 4                                    x = 2

Therefore, the roots of the function x² - 6x + 8 are x = 4 and x = 2.

Answer:

85 1/3

Step-by-step explanation:

All I did is multiply and got that.

I'm going to submit my finals, so hopefully it's not wrong. I don't think it's wrong though.

The surface area of the solid will be A=327.5 square inches and the lateral surface area will be A= 377.5 square inches.

The space occupied by any figure in the two-dimensional space is called an area. The area can be rectangular circular triangular types.

Here we have the figure made up by the two pyramids and one rectangular box. So we will find the surface area of the pyramid then the rectangular box and again the pyramid and will add all of them.

The Lateral surface area will be calculated as:-

A=2W√(w÷2)²+(h)²+w²

A=2x5√(5÷2)²+(3)²+5x5

A=152.5 +25

A=177.5 square inch

Area of lower pyramid= (1÷2)xbxh+w²

A=(1÷2)x5x7.5 + 25 =75+25= 100

Area of the rectangular box= 4(w²)=4(5x5)=100

So total lateral surface area will be =100+100+177.5=377.5 square inch

(2)The surface area will be calculated as:-

A=2W√(w÷2)²+(h)²

A=2x5√(5÷2)²+(3)²

A=152.5 square inches

Area of lower pyramid= (1÷2)xbxh

A=(1÷2)x5x7.5  =75 square inches

Area of the rectangular box= 4(w²)=4(5x5)=100

So total surface area will be =100+75+152.5=327.5 square inch

Hence the surface area of the solid will be A=327.5 square inches and the lateral surface area will be A= 377.5 square inches.

Answer:

The answer is 18 pounds per bucket.

In this question, we are given the expression that relates the pounds of lobster to the number of buckets:

[tex]\displaystyle \frac{\text{450 pounds}}{\text{25 buckets}}[/tex]

This fraction is presented to give a proportion of pounds of lobster to the number of buckets these lobsters inhabit.

To solve this problem, we need to know exactly how this rate will work.

A rate is the same thing as a fraction, percentage, or decimal. All of these forms are convertible between one another.

For instance, if we took 25%, we know that by dividing this by 100, we receive a decimal form (0.25) or a fractional form (1/4).

We can apply the same principle here.

Part I - Set up the Rate

To solve, set up the rate:

[tex]\displaystyle \frac{450 \ \text{pounds}}{25 \ \text{buckets}}[/tex]

Part II - Find the GCF

Then, find the Greatest Common Factor (GCF) of the two digits:

Check for common factors between the two trees:

Since 25 is the greatest of the three factors, it is the GCF.

Part III - Apply the GCF

Divide both the numerator and the denominator by 25:

[tex]\displaystyle \frac{450}{25} = 18[/tex]

[tex]\displaystyle \frac{25}{25} = 1[/tex]

Part IV - Simplify

Set up the new fraction:

[tex]\displaystyle \frac{18}{1}[/tex]

Anything divided by 1 does not change:

[tex]\displaystyle \frac{18}{1} = 18[/tex]

Since we got 18 an answer, this means that there are 18 pounds of lobster per bucket.

Step-by-step explanation:

so, that means we want to find the time t (days) after which N = No/2

because "half-life" means the amount of time until half of the substance has disappeared (or transformed into something else).

so, we have

No/2 = No × e^(-0.1481×t)

No = 2× No × e^(-0.1481×t)

1 = 2×e^(‐0.1481×t)

1/2 = 0.5 = e^(-0.1481×t)

ln(0.5) = -0.1481×t

t = ln(0.5)/-0.1481 = 4.680264555... ≈ 4.7 days

The term, "variability" describes how far apart data points lie from each other, and from the center of a distribution.

Along with measures of central tendency, measures of variability give you descriptive statistics that summarize your data.

Variability is also referred to as spread, scatter or dispersion.
