The person who runs fastest is Zach.

Ron runs 9 feet per second: 9 ft/s

Zach runs 410 feet in 49 seconds:

410/49 ft/s

=8.36 ft/s

= 8.4 ft/s (Approximately)

Katie runs 1 mile in 412 seconds:

1 mile = 5280 ft

5280/412 ft/s

=12.8 ft/s

Noah  runs 870 feet in 1 minute:  

= 870/60 ft/s

= 14.5 ft/s

Hence,

Ron 9 feet per seconds

Zach 8.4 feet per seconds

Katie  12.8 feet per seconds

Noah 14.5 feet per seconds

The linear function f with the given values f(0) = 2, f(3) = -1 is f(x) = -x + 2.

What is Linear Function?

A straight line on the coordinate plane is represented by a linear function.

The linear function formulas are:

Here, we have

The given functions are f(0)=2 and f(3) = -1

For f(0) = 2

Coordinate: (0,2)

y-intercept, c: 2

For f(3) = -1

Coordinate: (3,-1)

gradient or slope, m when x₁ = 0, y₁ = 2, x₂ = 3, y₂ = -1

=( y₂-y₁)/(x₂-x₁)

= ( -1 -2)/(3 - 0)

= -3/3

= -1

The linear equation is in the slope-intercept form, y=mx+c

f(x) = -x+2, where -1 is the slope and 2 is the y-intercept.

Hence, The linear function f with the given values f(0) = 2, f(3) = -1 is f(x) = -x + 2.

As per the unitary method, the cost of 8 bottles is $6.48

Unitary Method:

Unitary method is the way of solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given,

Hawa buys 15 bottles of apple juice at the corner store for a total cost of $12.15.

Here we need to find the if each bottle costs the same amount, how much is 8 bottles of juice.

Let x be the cost of one bottle.

so, based on the unitary method we can written the situation as,

15 bottles = costs $12.15

Therefore, the cost of one bottle is.

x = 12.15/15

x = 0.81

So, the cost of 8 bottle is calculated by multiplying the cost of one bottle with 8,

Then we get,

=> 8 x 0.81

=> 6.48

Therefore, the cost of 8 bottles is $6.48

The letters for XYZ are in the wrong order.

The correct statement should be [tex]\triangle TUV \cong \triangle ZYX[/tex]

============================================

Further Explanation:

The order of the letters matters when writing congruence statements.

The claim is that [tex]\triangle TUV \cong \triangle XYZ[/tex]

The first two letters of each are "TU" and "XY" in that order.

But notice how TU has a single tickmark, while XY has a double tickmark. The two sides are clearly different.

--------

Instead, the statement should be: [tex]\triangle TUV \cong \triangle ZYX[/tex] because of the following three facts:

Notice that:

The arrangement of the points in increasing order of the slopes are (27, 2) and (243, 18),  (63, 9) and (84, 12), (45, 15) and (60, 20), (27, 12) and (72, 32), (15, 30) and (20, 40),  (12, 32) and (18, 48), (18, 63) and (24, 84)

Slope is defined as the change in y divided by the change in x. Mathematically:

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

To arrange the pair of points. You need to find the slope:

For (15, 30) and (20, 40):

x1 = 15, y1 =30 and x2 =20, y2=40

slope = (40-30)/(20-15) = 10/5 =2

For (12, 32) and (18, 48):

slope = (48-32)/(18-12) = 16/6 = 2.67

For (27, 12) and (72, 32):

slope = (32-12)/(72-27)  = 20/45 = 0.44

For (45, 15) and (60, 20):

slope = (20-15)/(60-45) = 5/15 = 1/3 = 0.33

For (27, 2) and (243, 18):

slope = (18-2)/(243-27) = 16/216 = 0.07

For (18, 63) and (24, 84):

slope = (84-63)/(24-18) = 21/6 = 7/2 = 3.5

For (63, 9) and (84, 12):

slope = (12-9)/(84-63) = 3/21 = 1/7 = 0.14

Therefore, the pairs of points in increasing order of the slopes are (27, 2) and (243, 18),  (63, 9) and (84, 12), (45, 15) and (60, 20), (27, 12) and (72, 32), (15, 30) and (20, 40),  (12, 32) and (18, 48), (18, 63) and (24, 84)

Answer:

2x2x3x5= 60

I hope you like it

Answer:

2 X 2 X 3 X 5

Step-by-step explanation:

We divide 60 by 2 as many times as possible to get 60 = 15 x 2 x 2. 2 is a prime number so we don't need to break the 2's down any more. Instead we break 15 down. 15 doesn't divide by 2 so we try the next prime number: 3 Divide 15 by 3 to get 15 = 5 x 3, and so 60 = 5 x 3 x 2 x 2. Now we collect the factors, so our final answer is 60 = 5 x 3 x 22.

The complement of a set is the set that includes all the elements of the universal set that are not present in the given set. Let's say A is a set of all coins which is a subset of a universal set that contains all coins and notes, so the complement of set A is a set of notes (which do not includes coins).

U = {2,3,6,9,10,13,14,17,19}, A =  {2,9,10}

set A complement are all the elements in the Universal set U not contained in set A. Those elements are in set A' =  { 3, 6, 13, 14, 17, 19}

The equation of line d that is perpendicular to line c is: y = 7/3x - 2/3.

Perpendicular lines have slope values, whose product is equal to -1, that is, they are negative reciprocals to each other. An equation in slope-intercept form is often written for a line as y = mx + b, where m = slope and b = y-intercept.

The slope of y - 3/7x + 4 is -3/7. The negative reciprocal of -3/7 is 7/3. Therefore, the slope (m) of the perpendicular line d is 7/3.

Substitute m = 7/3 and (x, y) = (2, 4) into y = mx + b to find the value of b (y-intercept of the line):

4 = 7/3(2) + b

4 = 14/3 + b

-14/3 + 4 = b

(-14 + 12)/3 = b

-2/3 = b

b = -2/3.

To write the equation of line d, substitute m = 7/3 and b = -2/3 into y = mx + b:
