Answer:

3/4

Step-by-step explanation:

1 / (1/3) = 3

1/4 * 3 = 3/4

Let's try all of the possible answer choices.

Any result that is even, we cross off the list. Otherwise we have our answer.

If c = -8, then c-8 = -8-8 = -16 which is even. Cross this off the list

If c = 0, then c-8 = 0-8 = -8, which is even. Cross this off the list.

If c = -5, then c-8 = -5-8 = -13, which is odd. We have our answer

If c = 10, then c-8 = 10-8 = 2, which is even. Cross this off the list

The amount of time it takes to ride 26 miles is 2.89 hours.

Step-by-step explanation:

Given : You ride your bike at 9 miles per hour.

To find : How long it will take you to ride 26 miles ?

Solution :

The equation given is [tex]9\times t=26[/tex]

Using distance formula,

[tex]\text{Distance}=\text{Speed}\times \text{Time}[/tex]

According to formula t represent the time taken to cover the distance.

Your speed in miles per hour is 9 miles per hour.

The number of miles you've traveled so far is 26 miles.

Solving the equation,

[tex]9\times t=26[/tex]

[tex]t=\frac{26}{9}[/tex]

[tex]t=2.89[/tex] hours

The amount of time it takes to ride 26 miles is 2.89 hours.

Answer:

(b) y=-3/4x-8

Step-by-step explanation:

The graph that will be perpendicular to the graph 4x - 3y = -12

If this equation is represented in form of the straight line equation y = mx + b

it will change to 3y = 4x + 12

therefore y = (4/3)x + (12/3)

y = (4/3)x + 4

which implies that m = 4/3 while b = 4

However for the line that will be perpendicular to the graph, its slope m1 must be negative inverse of the slope of the initial graph

This is because m x m1 = -1

therefore m1 = -1/m

this implies that the correct answer must have a slope of -1/(4/3) = -3/4

The correct answer can then be analysed by expressing all options with y = mx + b

(a) In form of y = m1x + b, 4x+3y=12 becomes y = -4/3x + 4 (m1 = -4/3: wrong)

(b) In form of y = m1x + b, y=-3/4x-8 has m1 = -3/4 (correct)

(c) In form of y = m1x + b, y=3/4x+1 has m1 = 3/4 (wrong)

(d) In form of y = m1x + b, 3x-4y=1 becomes y = 3/4x - 1/4 (m1 = 3/4: wrong)

Answer:

Odds in against the team winning is 5 : 3

Step-by-step explanation:

Consider the provided information.

The odds against is the ratio of how many ways an outcome can't take place compared to how many ways it can take place.

Here the probability of winning its next match is 3/8.

That means total number of outcomes are 8.

Favorable outcomes are 3.

Therefore, the unfavorable outcomes are 8-3=5.

We need to find the odds against the team winning its next match.

Therefore, odds in against the team winning is 5 : 3

The probability of odds against the team winning is [tex]\frac{5}{8}[/tex]

To find the odds against the rugby team winning, subtract the probability of winning from 1 to get the probability of not winning and form a ratio of these probabilities, resulting in odds of 5:3 against the team winning.

The student is asking about the calculation of odds against a rugby team winning its next match given a certain probability of winning. First, we need to understand the probability of the team not winning (losing or drawing) because the odds against the team winning would be the ratio of it losing to it winning. Since the probability of winning is given as 3/8, the probability of not winning is 1 - 3/8 = 5/8. The odds against the team winning are therefore expressed as the ratio of the probability of not winning to the probability of winning, which is 5/8 to 3/8, or simply 5:3 when converted into odds format.

The first plant produces 5x + 26 more items daily than the second​ plant

Given that , A company has two manufacturing plants  

The daily production levels of one company is 7x + 19 items  

And daily production levels of another company is 2 x - 7 items

To find the number of items first plant produce more than the second plant, wed need to subtract the number of items produced by second plant from the the number of items produced by first plant.

Extra items produced by 1st plant = daily production of 1st plant - daily production of 2nd plant

Extra items produced count = 7x + 19 – (2x – 7)

= 7x + 19 – 2x + 7  

= 7x – 2x + 19 + 7 = 5x + 26  

Hence, the 1st plant produces 5x + 26 items more than 2nd plant

Step-by-step explanation:

If you want fraction form then the

X-Intercept: (6/5,0)

Y-Intercept (0,3/4)

To find the x intercepts, you have to plug y=0 into the equation. After you plug in y=0, you get the equation 5x-9=-3 and once you solve that, you find that the x intercept = 1.2

Likewise, to find the y intercepts, you would plug x=0 into the equation. Once you do that, you get the equation -9=-8y-3 and when you solve for y you get an intercept of 3/4

Dimension of rectangular parking lot is width = 112.882 feet and length = 132.882 feet

Given that  

Area of rectangular parking lot = 15000 square feet

Length is 20 feet more than the width.

Need to find the dimensions of rectangular parking lot.

Let assume width of the rectangular parking lot in feet be represented by variable "x"

As Length is 20 feet more than the width,

so length of rectangular parking plot = 20 + width of the rectangular parking plot

=> length of rectangular parking plot = 20 + x = x + 20

The area of rectangle is given as:

[tex]\text {Area of rectangle }=length \times width[/tex]

Area of rectangular parking lot = length of rectangular parking plot [tex]\times[/tex] width of the rectangular parking

[tex]\begin{array}{l}{=(x+20) \times (x)} \\\\ {\Rightarrow \text { Area of rectangular parking lot }=x^{2}+20 x}\end{array}[/tex]

But it is given that Area of rectangular parking lot = 15000 square feet

[tex]\begin{array}{l}{=>x^{2}+20 x=15000} \\\\ {=>x^{2}+20 x-15000=0}\end{array}[/tex]

Solving the above quadratic equation using quadratic formula

General form of quadratic equation is  

[tex]{ax^{2}+\mathrm{b} x+\mathrm{c}=0[/tex]

And quadratic formula for getting roots of quadratic equation is

[tex]x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]

In our case b = 20, a = 1 and c = -15000

Calculating roots of the equation we get

[tex]\begin{array}{l}{x=\frac{-(20) \pm \sqrt{(20)^{2}-4(1)(-15000)}}{2 \times 1}} \\\\ {x=\frac{-(20) \pm \sqrt{400+60000}}{2 \times 1}} \\\\ {x=\frac{-(20) \pm \sqrt{60400}}{2}} \\\\ {x=\frac{-(20) \pm 245.764}{2 \times 1}}\end{array}[/tex]

[tex]\begin{array}{l}{=>x=\frac{-(20)+245.764}{2 \times 1} \text { or } x=\frac{-(20)-245.764}{2 \times 1}} \\\\ {=>x=\frac{225.764}{2} \text { or } x=\frac{-265.764}{2}} \\\\ {=>x=112.882 \text { or } x=-132.882}\end{array}[/tex]

As variable x represents width of the rectangular parking lot, it cannot be negative.

=> Width of the rectangular parking lot "x" = 112.882 feet  

=> Length of the rectangular parking lot = x + 20 = 112.882 + 20 = 132.882

Hence can conclude that dimension of rectangular parking lot is width = 112.882 feet and length = 132.882 feet.

Answer:

Total savings  = $63  +  12 ( m)  

: m  = number of driveways shoveled

Step-by-step explanation:

Here, the money earned for each road David shovels = $15

The number of driveway shoveled by David = 12

The total money saved  David has after he is done with his work = $243

Now, The number of money saved by shoving 12 driveways  

= 12 x ( Money earned by shoveling 1 driveway)

= 12 x ( $15) = $ 180

Total savings  = His previous savings  + Money earned from Shovel work

⇒  $243  =   His previous savings + $ 180

⇒ His previous savings = $243  - $180 = $63

Now, we can write his total savings as:

Total savings  = $63  + 12 ( m)  

: m  = number of driveways shoveled
