9 feet is the same as = 2.74 m

Given

1 ft≈ 0.305 m

To find out 9 feet is the same as how many meters:

To convert a foot measurement to a meter measurement, multiply the length by the conversion ratio.

Since one foot is equal to 0.3048 meters, you can use this simple formula to convert:

meters = feet × 0.3048

= 9 * 0.3048

= 2.7432 m

The length in meters is equal to the feet multiplied by 0.3048.

Hence the answer is the 9 feet is the same as meters = 2.74m.

The value of v is -12.5 when u = 15, t = 8, and s = 40.

According to the question,

We have the following expression:

s = (u+v)[tex]t^{2}[/tex]

We have the following values:

u = 15, t = 8, s = 40

Now, we can easily find the value of v by putting all these values in the given expression.

So, we have the following expression:

40 = (15+v)8*8

40 = (15+v)16

Multiplying 16 into the bracket:

40 = 15*16+16v

40 = 240+16v

Subtracting 240 from both sides:

40-240 = 16v

-200 = 16v

Dividing by 16 on both sides:

-200/16 = v

v = -12.5

Hence, the value of v is -12.5 when u = 15, t = 8, and s = 40.

1 m = 1 metros = 10 decímetros = 10 dm

3.5 metros = 3.5 * 10 = 35 decímetros

Answer: only 1

Step-by-step explanation:

Answer: One-fifth.

Step-by-step explanation:

2/5 is two-fifths, 3/5 is three-fifths, and so on.

1/10 is one-tenth, 2/10 is two-tenths, and so on.

The equation of the function is: y = 11.5x.

The slope = 11.5 garbage bag per hour.

Y-intercept = 0 bag at 0 hour.

The domain: number of hours

Range of the function: number of garbage bags filled.

138 bags will be filled in 12 hours.

The equation of a function can be written as y = mx + b in slope-intercept form. Here, we have:

Given the graph with the points that represents the number of garbage bags filled as a function of time as:

(6, 69); (5, 57.5); (4, 46); (2, 23); (1, 11.5); (3, 34.5)

Use two points, (6, 69) and (4, 46) to find the slope of the function:

Slope (m) = change in y / change in x = (69 - 46)/(6 - 4)

Slope (m) = 23/2

Slope (m) = 11.5

To find the y-intercept (b), substitute m = 11.5 and (x, y) = (6, 69) into y = mx + b:

69 = 11.5(6) + b

69 = 69 + b

69 - 69 = b

b = 0

To write the equation of the function, substitute m = 11.5 and b = 0 into y = mx + b:

y = 11.5x + 0

y = 11.5x

The slope, 11.5, means 11.5 garbage bags were filled per hour.

Y-intercept is zero, which means no bag was filled at 0 hour.

The domain is the set of the number of hours, while the range of the function is the set of number of garbage bags filled.

To find the number of garbage bags that volunteers fill in 12 hours, substitute x = 12 into y = 11.5x:

y = 11.5(12)

y = 138 bags.

  (c)  50 units²

Step-by-step explanation:

You want to know the area of the rectangle with vertices (-5, 5), (-1, 7), (4, -3), and (0, -5).

The distance formula can be used to find the lengths of the sides. That formula is ...

  d = √((x2 -x1)² +(y2 -y1)²)

The distance between the first two points is ...

  d = √((-1 -(-5))² +(7 -5)²) = √(4² +2²) = √20

The distance between the next two points is ...

  d = √((4 -(-1))² +(-3 -7)²) = √(5² +(-10)²) = √125

The area is the product of two adjacent side lengths:

  A = LW

  A = (√125)·(√20) = √(125·20) = √2500 = 50 . . . . square units

The area of the rectangle is 50 units².

The probability that an individual man’s step length is less than 2.2 feet is 0.10 or 10%

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean  and standard deviation , the z-score of a measure X is given by:

Z = (X - mean)/S.D

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 2.8 feet and a standard deviation of 0.5 feet.

Find the probability that an individual man’s step length is less than 2.2 feet.

This is the p-value of Z when X = 2.2. So

Z = (2.2 - 2.8)/0.5

Z = 0.6/0.5 = 1.2

Z = 1.2

has a p-value of 0.10

Therefore, the probability that an individual man’s step length is less than 2.2 feet is 0.10 or 10%

Answer:you have 2 lines that cross.

the left angle formed is equal to 3x + 8

the right angle formed is equal to 5x - 20.

the bottom angle formed is equal to 5x + 4y

since the lines are crossed, the opposite angles to each other are equal.

this means that:

3x + 8 = 5x - 20

solve for x to get x = 14 degrees.

the angle on the left side will be equal to 3(14) + 8 = 50 degrees.

the angle on the right side will be equal to 5(14) - 20 = 50 degrees.

this is at it should be since the angles are equal to each other.

since the sum of the 4 angles formed is equal to 360 degrees, the sum of the remaining 2 angles is equal to 260 degrees.

since those 2 angles are equal, then each one must be equal to 130 degrees.

one of those angles is equal to 5x + 4y.

you get 5x + 4y = 130

since x was already found to be 14, replace x with 14 to get:

5(14) + 4y = 130

solve for y to get y = (130 - 5(14)) / 4 which is equal to 15 degrees.

when x = 14 and y = 15, 5x + 4y = 5(14) + 4(15) = 70 + 60 = 130 which confirms the value of 15 for y is good.

your answers are:

x = 14 degrees

y = 15 degrees

2 of the angles measure 50 degrees each.

2 of the angles measure 130 degrees each.

Answer:

y = 5x/6 + 3/2

Step-by-step explanation:

First, find the slope (m):

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

m=(9-4)/(9-3)

m=5/6

y=mx+b ==> slope-intercept form equation

y = 5x/6 + b==> substitute the value of the slope for m

9 = 5(9)/6 + b ==> substitute a point (x, y) or (9, 9) into the equation

9 = 45/6 + b ==> simplify

(9 = 45/6 + b)*6 ==> multiply the equation by 6 to remove denominators

54 = 45 + 6b ==> simplify

54 - 45 = 45 - 45 + 6b ==> solve for b

9 = 6b

9/6 = 6b/6

b = 3/2

y = 5x/6 + 3/2 ==> plug in b for the slop-intercept equation

Answer:

a = 70 degrees

b = 20 degrees

c = 20 degrees

Step-by-step explanation:

First, we can find "c":

angleBCA = 90

angleBCA = angleBCD + c

90 = 70 + c

90 - 70 = c

20 = c

Knowing "c", we can find "a".

angleADC = 90

triangleADC = 180

triangleADC = angleADC + c + a

180 = 90 + 20 + a

180 = 110 + a

180 - 110 = a

70 = a

Knowing "a", we can find "b".

angle BCA = 90

triangleACB = 180

triangleACB = angleBCA + a + b

180 = 90 + 70 + b

180 = 160 + b

180 - 60 = b

20 = b
