6m - 3k when k=2 and m=7

Answer:

x= 5

Step-by-step explanation:

You need to get rid of the fraction first and to do that you muliply the whole equation by 5 so that your new equation reads 4x+25=45. Then you subtract 25 from both sides so you have 4x=20. Divide both sides by 4 so x=5.

Answer:

8 1/2 feet

Step-by-step explanation:

Here is the complete question

A window shaped like a parallelogram has an area of 73 2/3 square feet. The height of the window is 8 2/3 feet. How long is the base of the window?

A parallelogram is  quadrilateral that has two pairs of parallel sides. The opposite sides  equal in length

Area = base x height

73 2/3 = 8 2/3 x base

divide 73 2/3  by 8 2/3

221/3 x 3/26 = 8 1/2 feet

Answer:

4.63

Please give me brainliest, I really need it.

The value of 4.63 falls within the interval (4.66, 4.791) where 95% of the sample means occur option (B) is correct.

It is defined as the sampling distribution following an approximately normal distribution for known standard deviation.

The formula for finding the confidence interval for population standard deviation as follows:

[tex]\rm s\sqrt{\dfrac{n-1}{\chi^2_{\alpha/2, \ n-1}}} < \sigma < s\sqrt{\dfrac{n-1}{\chi^2_{1-\alpha/2, \ n-1}}}[/tex]

Where s is the standard deviation.

n is the sample size.

[tex]\chi^2_{\alpha/2, \ n-1} and \chi^2_{1-\alpha/2, \ n-1}[/tex]  are the constant based on the Chi-Square distribution table.

α is the significance level.

σ is the confidence interval for population standard deviation.

Calculating the confidence interval for population standard deviation:

We know significance level = 1 - confidence level

It is given that:

Mean of the population x = 4.73

Standard deviation s = 0.865

Sample size n = 200

The interval where 95% of the sample means occur:

Lower limit = 4.73 - 0.865/√200

Lower limit = 4.66

Upper limit = 4.73 + 0.865/√200

Upper limit = 4.791

The interval = (4.66, 4.791)

Thus, the value of 4.63 falls within the interval (4.66, 4.791) where 95% of the sample means occur option (B) is correct.

Answer: $178.50

Step-by-step explanation:

If Alex is paid a piecework rate of $8.50 per motor, then;

Price per motor assembly = $8.50

By assembling 21 motors Alex gets,

1 motor = $8.50

21 motors = (21 * $8.50) / 1

= $178.50 / 1

= $178.50

By assembling 21 motors,

Alex gets $178.50

Answer: 33

If you put all the numbers In order from least to greatest and find the middle number you'll get the answer

Answer: See explanation

Step-by-step explanation:

We should note that the hypothenuse is the longest side in a triangle. Therefore, the length of the other side will be represented by x. This is then solved below:

x² + 3² = 5²

x² + 9 = 25

x² = 25 - 9

x² = 16

x = ✓16

x = 4cm

The other leg is 4cm

Joni shouldn't have added the hypothenuse to the other leg but rather subtracted the square of the other leg from the square of the hypothenuse and then find the square root.

Answer:

54

Step-by-step explanation:

The given number to be increased = 36

The percentage by which the number is increased = 50%

In increasing a number by a percentage, we find the value of the percentage increase of the number and add to the number as follows;

50% of 36 + 36 = 50/100 × 36 + 36 = 54

Second method

The find the number obtained by increasing a number by a given percentage 'x', we add 100 to the give percentage and multiply the result by the number and hen divide the final result by 100 as follows;

36 increased by 50% = (100 + 50) × 36/100 = 54

Answer:

y = -x + 11

Step-by-step explanation:

The slope of the line y = -x + 4 is -1.

So the slope of our line is also -1 ( because they are parallel).

First use the point-slope form of the equation of a line:

y - y1 = m(x - x1) where m is the slope and (x1, y1) is a point on the line.

Here m = -1 and (x1, y1) = (6, 5).

So we have:

y - 5 = -1(x - 6)

y - 5 = -x + 6

y = -x + 11  <------ Slope intercept form.

Answer:

7 cm by 6 cm by 18 cm

Step-by-step explanation:

Given :

Volume of candle = 270cm³

Height = 18cm

Triangular base = 5cm

Width of candle = 7cm

Volume = Area of base * height

270cm³ = Area of base * 18

Area of base = 270cm³ / 18cm

Area of base = 15 cm²

Using this to find the height of triangular prism :

Area = 1/2 * base * height

15cm² = 1/2 * 5 * height

15cm² = 2.5 *. Height

Height = 6 cm

Hence, the dimension of triangular prism is : 7cm by 6cm by 18cm
