Determine the slope between (4, 2) and (-3, 5) ~hurry please~

SpyIntel [72]

Answer:

A.-3/7

Step-by-step explanation:

the slope formula is

m = (y2 - y1) / (x2-x1)

The point (4, 2) is (x1, y1) and the point (-3, 5) is (x2, y2). Now you have to substitute in the slope formula:

m = (5 - 2) / (-3 - 4)

m = 3 / -7

m = -3/7

The average marks of the first 10 students are 17 and that of the next 15 students is 18. find the mean of 25 students?

Ray Of Light [21]

Answer:

The mean of 25 students is 17.6

Step-by-step explanation:

The formula of the mean (average) is mean (average) = $\frac{S}{N}$ , where S is the sum of the data, and N is the number of the data

∵ The average marks of the first 10 students are 17

- That means the mean is 17 and the number of students is 10

∴ Average = 17

∴ N = 10

∵ Average = $\frac{S}{N}$

- Substitute average by 17 and N by 10

∴ 17 = $\frac{S}{10}$

- Multiply both sides by 10

∴ 170 = S

∴ The sum of the marks of the first 10 students is 170

∵ The average of the next 15 students is 18

∴ Average = 18

∴ N = 15

- Substitute average by 18 and N by 15

∴ 18 = $\frac{S}{15}$

- Multiply both sides by 15

∴ 270 = S

∴ The sum of the marks of the next 15 students is 270

Now to find the mean of 25 students and the two sums and divide the answer by 25

∵ S = 170 + 270

∴ S = 440

∵ N = 25

∴ Mean = $\frac{440}{25}$

∴ Mean = 17.6

The mean of 25 students is 17.6

how high up on a building will 15 foot ladder reach if the foot of the ladder is placed 5 feet from the building? (be sure to in

mezya [45]

Use the Pythagorean theorem:
$5^2+x^2=15^2 \\
25+x^2=225 \\
x^2=225-25 \\
x^2=200 \\
x=\sqrt{200} \\
x=\sqrt{100 \times 2} \\
x=10\sqrt{2} \\
x \approx 14.14$

The ladder will reach approximately 14.14 feet (exactly 10√2 feet) up on the building.

PLEASE HELP OMG the side lengths of triangle MNO are given: MN=5, NO=4, OM=2.5. the triangle is dilated by a scale factor of k w

elena-14-01-66 [18.8K]

The value of the scale factor k, is 1.5

<h3>Perimeter</h3>

The perimeter of a shape is the sum of the side lengths of the shape

<h3>Dimensions </h3>

The dimensions of the triangle MNO are given as:

$MN = 5$

$NO = 4$

$OM = 2.5$

Calculate the perimeter of the triangle as follows:

$MNO=5 + 4 +2.5$

$MNO=11.5$

Divide 17.25 by 11.5 to calculate the scale factor (k)

$k = \frac{17.25}{11.5}$

$k = 1.5$

Hence, the scale factor is 1.5
