the solution of this question

Answer:

No

Step-by-step explanation:

For a proportional relationship :

y = kx

Where , k = constant of proportionality

Taking the first set of data:

x = 50 ; y = 10

10 = 50k

k = 10/ 50 = 1/5

Hence, the proportional equation or relation is :

y = 1/5x

Check if this is true for other data points on the data :

Taking the second data point :

x = 85 ; check if y will be 20

From :

y = 1/5x

y = 1/5*85

y = 85/5

y = 17

Since ;

y value from the equation isn't the same as that in the table, then the table does not show a proportional relationship.

Answer:

I believe the answer is 8.16 pardon me if it's wrong.

Answer:

8.18

Step-by-step explanation:

First, note that 8.175 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:

Integer Part: 8

Fractional Part: 175

To round 8.175 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part.

We use the following rules to round 8.175 to the nearest hundredth:

A) If the last digit in the fractional part of 8.175 is less than 5, then simply remove the last the digit of the fractional part.

B) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.

C) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.

D) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.

With 8.175, rule B applies and 8.175 rounded to the nearest hundredth is:

8.18

8 because the opposite of 8 is -8 and the opposite of that is 8 so yep 8 is the answer

Answer:126m2

Step-by-step explanation:

Since they are both rectangles, use the area of a rectangle equation to find it which is length times width. What I would do first is find the area of the big rectangle which is 10*15 which is 150. Then I would find the area of the white space which is 6*4 which is 24. Since the white space is not part of the question, subtract 24 from 150 which gets you 126m2. Hope this helps :)

Answer:

There are 6 boxes

Step-by-step explanation:

We know there are 45 frames and 3 broken ones, so there are 48 frames in total.

We know there are 8 boxes that have the frames.

let x equal the amount of picture frames in a box

8x=48

8x/8 = 48/8

x=6

side opposite of 30° = x

side opposite of 60° = x√3

side opposite of 90° = 2x

Answer:

5:12

Step-by-step explanation:

$1.20 = (1x100 + 20) cents = 120 cents

You get a ratio of 50:120.

Since both are divisible by 10, divide both sides by 10.

You get 5:12.

Since 5 and 12 share no common factors other than 1, this is the simplest form.

Answer:

[tex]y = \frac{11}{8}x + 50[/tex]

Step-by-step explanation:

Given

See attachment for plot

Required

The line of best fit

From the attached plot, we have:

[tex](x_1,y_1) = (0,50)[/tex]

[tex](x_2,y_2) = (80,160)[/tex]

Calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{160 - 50}{80-0}[/tex]

[tex]m = \frac{110}{80}[/tex]

[tex]m = \frac{11}{8}[/tex]

The line of best fit is then calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

This gives:

[tex]y = \frac{11}{8}(x - 0) + 50[/tex]

[tex]y = \frac{11}{8}x + 50[/tex]

Answer:

95 points

Step-by-step explanation:

Given

[tex]n = 370[/tex] --- expected point

See attachment for points

Required

An inequality to determine the points needed

First, we calculate the points (p) Lesha has already accumulated.

[tex]p = Test\ 1 + Test\ 2 + Test\ 3[/tex]

[tex]p = 75 + 100 + 100[/tex]

[tex]p = 275[/tex]

Let the number of points needed be t.

So:

[tex]p + t = 370[/tex] ---- i.e. She must score a total of 370

Make t the subject

[tex]t = 370 -p[/tex]

Substitute 275 for p

[tex]t = 370 -275[/tex]

[tex]t = 95[/tex]

Answer:94.5

Step-by-step explanation:

Step-by-step explanation:

you know that QPS adds up to 47

so the sum of RPS and QPR shoukd = 47

(3x - 38) + (7x - 95) = 47

you then solve for x then you can use that to find QPR

Answer:

16 kg/cm^2

Step-by-step explanation:

200cm^3=32kg/cm^2

Answer:

3 1/3

Step-by-step explanation:

super easy, just multiply them

5/1*1/3 and you get 10/3 and you simplify and get 3 1/3 pizza

Answer:

3 1/3 pizzas

Step-by-step explanation:

Take 2/3 and multiply it by 5/1. You get 10/3, which is an improper fraction. You take that and simplify it. I know 9 goes into 3 3 times, so that means those boys had 3 1/3 pizzas.

(Can I get a brainliest?)

Answer:

9/3

Step-by-step explanation:

9/3 = 3

Answer:

9/3

Step-by-step explanation:

Well we know that it is not 2/3 or 1/3 because those do not equal a whole number as they are decimals.

5/3 is equivalent to 1 2/3. Which we already determined that 2/3 was a decimal and not a whole number.

9/3 is equivalent to 3, and 3 is a whole number.

Hope this was a bit easier to understand.
