a triangle has two sides of length 18 and 3. what is the largest possible whole-number length for the third side?

Answer:

34 dollars and 6 cents

Step-by-step explanation:

1 percent = 0.26

0.26 x 31 = 8.06

26 + 8.06 = 34 dollars and 6 cents

I believe it is 34.06

Answer: x= (−∞,∞)

Step-by-step explanation:

3+8x+6 = 5(x+2) + 3x-1

9+ 8x = 5x +10 + 3x -1

9 + 8x = 8x +9

Subtract nine on both sides

8x= 8x

Answer:

176cm

Step-by-step explanation:

therefore r=13÷2 =r=7.5. and pieces =22÷7

then we substitute

The coordinate (4, 3) is the solution of the following system of equations:

y = 1/2x + 1 and y = -x + 7

y = x - 1 and y = 1/4x + 2

The solution implies that the coordinate is the: point of intersection.

The solution to a system of equations are the coordinate of the point where the two lines that represent the equations of the system intersect each other. The coordinate of x and the coordinate of y, when plugged into  any of the equations would be true.

The graph of the system of equations, y = x - 1 and y = 1/4x + 2 shows that both equations intersect at the point with the coordinate (4, 3) [see the graph in figure 1].

Also, the graph in figure two shows that y = 1/2x + 1 and y = -x + 7 also intersect at (4, 3).

Therefore, we can state that, the system of equations with (4, 3) as the solution are:

y = 1/2x + 1 and y = -x + 7

y = x - 1 and y = 1/4x + 2

The solution means point of intersection.

You want the steps involved in factoring 3x² +13x -10 by grouping.

To fill in the blanks, you need to know the product of the first and last coefficients, and the factor pairs of that product that have a sum equal to the middle coefficient.

   3(-10) = -30 = (-1)(30) = (-2)(15) = (-3)(10) = (-5)(6)

The sums of these factor pairs are 29, 13, 7, 1. The sum of interest is ...

  -2 + 15 = 13

These are the values that go in the first pair of blanks.

  = 3x² -2 x + 15 x -10

We want to identify the common factor for each pair of terms:

  = x (3x -2) + 5 (3x -2)

Finally, the common factor (3x -2) is removed and we have ...

  = ( x + 5 )(3x -2)

There is a dramatic change in desert temperatures from day to night because B. of the lack of water.

It should be noted that because the air in the desert is so dry, heat escapes quickly at night, the temperature can vary dramatically from day to night. The temperature during the day averages 38°C, while at night it can drop to -4°C in some deserts. The temperature varies greatly depending on where you are in the desert.

During the day, the sand's radiation from the sun's energy superheats the air, causing temperatures to rise. And, because the desert air is so dry, heat escapes quickly at night, according to NASA. The desert biomes are the driest of all biomes.

Answer:

a) 45

b) 54

Step-by-step explanation:

a) To be able to round up to the nearest 10, the number in the "ones column" needs to be 5 at the minimum.

You could argue it could be a decimal point however, you shouldn't really have a decimal of a bead ( it's possible but it over complicates the answer ) and, it's to the nearest 10, not nearest one decimal point for example.

Therefore, the min is 45 beads

b) ( The above poster was correct oops, I made a silly mistake )

The max is 54 beads as if anything in the ones column is under 4, you can't round up to the nearest 10. Hence it remains as 50 when rounding

Therefore, the max is 54 beads

Answer:

Lateral Surface Area = 1848 m^2 (does not include the top and bottom)

Step-by-step explanation:

Vol Cylinder = pi*r^2 *h  

h = (3/2)r

Vol = pi*r^2((3/2)r)                     [We are told that the volume is 12,936 m^3]

pi*r^2((3/2)r) = 12,936 m^3  

pi*(3/2)*(r^3) = 12,936 m^3

pi*r^3 = (12,936 m^3)*(2/3)

pi*r^3 = 8,624 m

r^3 = (8,624 m)/(3.14)

r^3 = 2745.1

r = 14.0 m

Lateral Surface = 2*(pi)*r*h  [Lateral is just the curved portion of the right cylinder.

Lateral Surface Area = 2*(3.14)*(14.0)(21.0)

The inequality that represents all possible combinations of x, the number of monitors, and y, the number of keyboards, the university can buy for the computer lab is 250x + 50y <= 4500

Which inequality represents all possible combinations?

The given parameters are:

Spending = At most $4,500

Cost of monitor (x) = $250 per unit

Cost of keyboard (y) = $50 per unit

The total spending is represented as

Total = 250 * x + 50 * y

This gives

Total = 250x + 50y

The spending is at most $4,500 i.e less than or equal to

So, we have

250x + 50y <= 4500

(a) The mean of Y is 100 meters, and the standard deviation of W is approximately 0.7348 meters.

(b) The mean of W is 100 meters, and the standard deviation of W is approximately 0.6935 meters.

a) To find the mean and standard deviation of Y, where Y = (X₁ + X₂) / 2, we use the properties of the mean and variance of a sum of independent random variables.

Mean of Y:

The mean of Y is simply the average of the means of X₁ and X₂, as the measurements are independent and have the same true height of 100 meters.

Mean(Y) = (Mean(X₁) + Mean(X₂)) / 2 = (100 + 100) / 2 = 100 meters

The standard deviation of Y:

When adding or subtracting independent random variables, the variances add up. Since the measurements are independent, we can use the formula:

Var(Y) = Var((X₁ + X₂) / 2) = (Var(X₁) + Var(X₂)) / 4

Now, calculate the variance of Y:

Var(Y) = (1.2² + 0.85²) / 4 ≈ 0.54

Standard deviation(Y) = √Var(Y)
                                    ≈ √0.54
                                      ≈ 0.7348 feet

b) Now, let's find the mean and standard deviation of W, where W = (1/3)X₁ + (2/3)X₂.

Mean of W:

Mean(W) = (1/3) * Mean(X₁) + (2/3) * Mean(X₂)
               = (1/3) * 100 + (2/3) * 100
               = 100 meters

The standard deviation of W:

To calculate the standard deviation of W, we need to find the variance of W and then take its square root.

Var(W) = (1/3)² * Var(X₁) + (2/3)² * Var(X₂)
            = (1/9) * 1.2² + (4/9) * 0.85²

Now, calculate the variance of W:

Var(W) = 0.0181 + 0.1956 =0.481

Standard deviation(W) = √Var(W)
                                     ≈ √0.481
                                      ≈ 0.6935 meters

So, the mean of W is 100 meters, and the standard deviation of W is approximately 0.6935 meters.

Answer:

1 = 45

2 = 75

3 = 60

4 = 41

5 = 71

6 = 109

Step-by-step explanation:

This may seem tricky at first, but if you follow the order of the numbers, you can find them fairly quickly using the values already given.

For angle 1:

The angle above it of 45 degrees is similar to angle 1, so that it automatically going to be 45

For angle 2:

The same concept for angle 1 applies for angle 2, so it will be 75 degrees.

For angle 3:

All triangles add up to 180 degrees. So, since we have angles 1, and 2, solve to find 3:

180 - 45 - 75 = 60

For angle 4:

All straight lines add up to 180 degrees. So solve to find angle 4 using the value we found for angle 3:

180 - 60 - 79 = 41

For angle 5:

Angle 5 is part of another triangle and we have two of the angles already. So solve to find angle 5 using the logic used to find angle 3:

180 - 41 - 68 = 71

For angle 6:

angles 5 and 6 are part of a straight line, so use the same logic for angle 4 and solve for angle 6:

180 - 71 = 109

Answer:

Part A

7x² + 5xy – 3

Part B

2x² – 8xy + 8

Step-by-step explanation:

Part A

the canned food collected so far is the sum of the canned food the three friends have by combining the expression

5xy + 2 + 6x² – 5 + x²

= 6x² + x² + 5xy + 2 – 5

= 7x² + 5xy – 3

Part B

The total of cans the friend need to collect to meet their goal is the canned food collected so far minus their targeted goal

= 9x² – 3xy + 5 – (7x² + 5xy – 3)

= 9x² – 3xy + 5 – 7x² – 5xy + 3

= 9x² – 7x² – 3xy – 5xy + 5 + 3

= 2x² – 8xy + 8

In general, the dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend.

Step-by-step explanation:

The dividend income on W number of shares of XYZ stock will be W * Y dollars if XYZ distributes a $Y per share dividend. This is because the dividend income is calculated by multiplying the number of shares that an investor owns by the amount of the dividend per share.

For example, if an investor owns W = 100 shares of XYZ stock and XYZ distributes a $Y = 5 per share dividend, then the investor's dividend income will be 100 * 5 = 500 dollars.
