is this proportional, non-proportional, both or neither?

Answer:

48

Step-by-step explanation:

Answer: C

Step-by-step explanation: it says that As Treatment X became more effective(In the graph it shows its increases) Treatment Y became less effective. The graph shows as one is increasing other decrease.

The scatter plot C best demonstrates this relationship.

An inverse relation is a relation in which value of two variable is inversely proportional to each other.

Given,

When treatment X became more effective, treatment Y became less effective.

Also, when treatment Y became more effective, treatment X became

less effective.

Therefore, variables X and Y follows inverse relationship.

Hence, Graph between X and Y is correct in option C.

The solution of expression [tex]0.1 \times (- 0.9 + - 0.2 \div - 0.5)[/tex] by using the BODMAS rule would be [tex]- 0.05.[/tex]

Used the concept of the BODMAS rule which states that,

The correct order in which to solve maths problems. Bodmas stands for B-Brackets, O-Orders (powers/indices or roots), D-Division, M-Multiplication, A-Addition, S-Subtraction.

Given that the expression is,

[tex]0.1 \times (- 0.9 + - 0.2 \div - 0.5)[/tex]

Solve the above equation by using the BODMAS rule,

[tex]0.1 \times (- 0.9 + - 0.2 \div - 0.5)[/tex]

It can be written as,

Answer:

length - 80

width - 80

Step-by-step explanation:

95*2 = 190

65*2 = 130

190+130 = 320

320/4 = 80

80 x 80 = 6400

95 x 65 = 6175

6400 > 6175

80 x 4 = 320 = both perimeters

Answer:

DABABY CONVERTIBLE GANG :)

Answer:

<A = 120degrees

<B = 80degrees

<C = 60degrees

<D = 100degrees

Step-by-step explanation:

For a cyclic quadrilateral, the sum of the adjacent angle of the quadrilateral are equal, hence;

<A + <C = 180

<B + <D  = 180

Substitute the given values

4x+20+4y = 180

4x+4y =1 60

x + y = 40 ...1

Similarly;

3x+5+7y - 5 = 180

3x+7y = 180 ....2

Solving simultaneously

x + y = 40 ...1 .....* 3

3x+7y = 180 ....2 ...... *1

__________

3x + 3y = 120 ...1 .

3x+7y = 180 ....2

Subtract

3y - 7y = 120 - 180

-4y = -60

y = 15

Since x+y = 40

x + 15 = 40

x = 40 - 15

x = 25

<A = 4x+20

<A = 4(25)+20

<A = 120degrees

<C = 180 - <A

<C = 180 - 120

<C = 60degrees

<B = 3x+5

<B = 3(25)+5

<B = 80degrees

<D = 180 - <B

<D = 180 - 80

<D = 100degrees

Answer:

20%

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 750 × 20/100

Discount = 750 x 0.2

You save = $150.00

Final Price = Original Price - Discount

Final Price = 750 - 150

Final Price = $600.00

Answer:

20%

Step-by-step explanation:

Just multiply 750 by 20%, and you will get 150. Subtract and you will get 600. That means my answer is correct.

A: More than half of the scores were 85% or greater.

E: At least one score was exactly 85%

Step-by-step explanation:

Here the 5 test would be taken in science so 85% would be the result of one of the test

Also 85% represent the median so it means there are 2 values more and 2 values less

So there are 3 results with 85% or greater

169. (m^2)

Step-by-step explanation:

lets first look at the smaller box. 7 x 7 is 49 so we have that answer. then 7 x 20 is 120. add those together and you get 169.

Answer:

The area of the composite figure is 189 square meters.

Step-by-step explanation:

First, partition the composite figure into 2 distinct shapes: a rectangle and a square on the top.

The formula for finding the area is: A = lw, or Area = length * width.

Area for figure number 1 (the square): 7 * 7 = 49

Area for figure number 2 (the rectangle): 20 * 7 = 140

Now, just add up both figures' areas, and find the answer:

140 + 49 = 189

Answer:

BC ≈ 15.01

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan65° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{BC}{7}[/tex] ( multiply both sides by 7 )

7 × tan65° = BC , then

BC ≈ 15.01 ( to the nearest hundredth )
