The Quantities And Y Are Proportional.2y5.85.87.57.511.211.2Find The Constant Of Proportionality (r)

Answers

Answer 1

Answer:

r = 1

Step-by-step explanation:

We know that x and y are proportional, with the the equation y = rx representing the proportional relationship. Where r = constant of proportionality

Thus the constant of proportionality would be:

r = y/x

Using any of the given pair of values from the table, say (5.8, 5.8),

r = 5.8/5.8

r = 1

Would you be breaking the speed limit in a 40 mi/h zone if you were traveling at 60km/h?

Answers

no you wouldn’t be breaking the speed limit! your absolutely fine!

Since 40 mi/h is greater than 60 km/h. Therefore, 60 km/h is not breaking the speed limit given.

We need to check if would you be breaking the speed limit in a 40 mi/h zone if you were travelling at 60 km/h.

What is the speed?

The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).

To check whether the speeds are the same, make their units the same.

As we know, 1 mile = 1.60934 km

So, 40 miles = 64.3736

≈64

Then, the speed =64 mile/h

Since 40 mi/h is greater than 60 km/h. Therefore, 60 km/h is not breaking the speed limit given.

Which function is not a linear function?

Answers

Answer: upper left corner

This is an absolute value function. It is a piecewise function composed of two different linear equations (they are glued together at the vertex), but it is not overall a single straight line compared to the other graphs.

find slope of the graph 9x-3y=15

Answers

ExplanationConvert the equation into slope-intercept form.

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept.

What we have to do is to make the y-term as the subject of equation.

[tex]9x - 3y = 15 \\ 9x - 15 = 3y \\ \frac{9x - 15}{3} = y[/tex]

Simplify

[tex] \frac{9x}{3} - \frac{15}{3} = y \\ 3x - 5 = y \\ y = 3x - 5[/tex]

From y = mx+b, the slope is 3.

Answer

James and Bethany Morrison are celebrating their 10th anniversary by having a reception at a local reception hall. They have budgeted $3500 for the reception. If the reception hall charges a $50 cleanup fee plus $34 per person find the greatest number of people that they may invite and still have within their budget.

Answers

Answer: See Below

Step-by-step explanation:

Create the equation:

$34 times the number of people plus the $50 cleaning fee has to be less than or equal to $3500

Or

34p + 50 <= 3500

34p <= 3450

p <= 101.470588....

We can have a part of a person attending the reception so we have to drop the remainder/decimal. Therefore the most amount of people that can attend the party and stay within budget is 101.

ASAP determine whether the polygons are similar

Answers

Answer:

Not similar

Step-by-step explanation:

For two triangles to be similar , their sides should be in the same ratio. Here the sides are ,

First ∆ = 5 , 5 & 3 Second ∆ = 6 , 6 & 4

Ratio of first sides :-

= 6/5 = 1.2

Ratio of second sides :-

= 6/5 = 1.2

Ratio of third sides :-

= 4/3 = 1.33

Since the ratio of all three sides are not same , Hence the two triangles are not similar.

Hence the two triangles are not similar .

Find three consecutive integers such that the sum of twice the second integer and 4 times the third integer is two less than seven times the first integer.

Answers

Answer:

12,13 and 14

Step-by-step explanation:

Let the three consecutive integers be n, n+1 and n+2

ATQ,

The sum of twice the second integer and 4 times the third integer is two less than seven times the first integer.

[2(n+1)+4(n+2)] = 7n-2

or

2n+2+4n+8=7n-2

Taking like terms together,

6n-7n = -2-8-2

n = 12

So,

First integer = 12

Second integer = 12+1 = 13

Third integer = 12+2 = 14

Hence, three consecutive integers are 12,13 and 14.

Under her cell phone plan, Lily pays a flat cost of $55.50 per month and $4 per
gigabyte. She wants to keep her bill at $63.10 per month. Write and solve an equation
which can be used to determine x, the number of gigabytes of data Lily can use while
staying within her budget.
equation:
answer x=

Answers

Answer:

Equation : y = 4x + 55.50

x = 1.9 gigabytes

Step-by-step explanation:

Given that:

Flat fee per month = $55.50

Cost per gigabyte = $4

Let,

x be the number of gigabytes.

y be the total cost

y = 4x + 55.50

Lily wants to keep her bill $63.10

63.10 = 4x + 55.50

63.10 - 55.50 = 4x

4x = 7.60

Dividing both sides by 4

[tex]\frac{4x}{4} = \frac{7.60}{4}\\x=1.9[/tex]

Hence,

Equation : y = 4x + 55.50

x = 1.9 gigabytes

Answer:

Equation: 4x+55.5=63.1

Arthur's dog, Shep, had to go on a diet. After three months of dieting, Shep had lost 16% of his weight, which was 24 pounds. How much did Shep weigh before he was put on a diet?

Answers

Answer: 150 pounds

Step-by-step explanation:

Let her initial weight be represented by x.

Since Shep had lost 16% of his weight, which was 24 pounds. Shep weight before he was put on a diet would be:

16% × x = 24

0.16 × x = 24

0.16x = 24

x = 24/0.16

x = 150 pounds

PLZ HELP Fast!!!!!!!!!!!!!!!!!Read the passage from Sugar Changed the World.In every single American slave state, the population of enslaved people kept rising even after the slave trade was abolished. That was because enough enslaved children were born, lived, and grew to become adults. There was just one exception to this rule: Louisiana, where the native-born enslaved population kept dropping. Sugar was a killer.Unlike the Caribbean, Louisiana has cold snaps. That put an additional pressure on the sugar harvest. Not only did the slaves need to harvest the cane in perfect rhythm with the grinding mills, but the entire crop had to be cut down between mid-October and December.
