Answer:

Step-by-step explanation:

first graph

<h2>height=constant* width ( direct variation describes a linear relation between 2 variable )</h2>

6=8x ⇒ x=6/8=0.75

h=0.75w

<h2>constant is 0.75</h2>

second graph:

<h2>height=constant/width ( inverse variation)</h2>

15=x/4 ⇒x=4*15 ⇒x=60

<h2>constant=60</h2>

For two quantities with inverse variation, as one quantity increases, the other quantity decreases. k(constant)=xy

A month with 31 days has the same number of Mondays and Wednesdays. How many of the seven days of the week could be the first da

Anvisha [2.4K]

Answer: b. 3

Therefore, we will have the same number of Mondays and Wednesdays if the first day is either Monday, Thursday or Friday. Making 3 possible days

Step-by-step explanation:

Given that there are 31 days in the month.

And there are equal number of Mondays and Wednesdays within a 7 day bracket.

30 - 4(7) = 3days

After four weeks we are left with three days.

So, if the first day is;

Monday - we will have 5 Mondays and Wednesdays each

Tuesday - we have more Wednesday

Wednesday - we will have more Wednesday

Thursday - we will have 4 Mondays and Wednesdays each

Friday - we will have 4 Mondays and Wednesdays each

Saturday - we will have more Monday

Sunday - we will have more Monday

Therefore, we will have the same number of Mondays and Wednesdays if the first day is either Monday, Thursday or Friday. Making 3 possible days

What are the coordinates of the midpoint of GH with endpoints (-2,5) and<br> H(4,1)?

kozerog [31]

Answer:

(1, 3)

Step-by-step explanation:

Given coordinates of 2 endpoints, G(-2, 5) and H(4, 1), midpoint of AB is calculated as shown below:

Midpoint (M) of GH, for G(-2, 5) and H(4, 1) is given as:

$M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2})$

Let $G(-2, 5) = (x_1, y_1)$

$H(4, 1) = (x_2, y_2)$

Thus:

$M(\frac{-2 + 4}{2}, \frac{5 + 1}{2})$

$M(\frac{2}{2}, \frac{6}{2})$

$M(1, 3)$

Coordinates of the midpoint of GH = (1, 3).
