Answer:

(a) -4 dollars

(b) +343 members

Step-by-step explanation:

(a) The change in the value of each share is the total amount of change divided by the number of shares:

change per share = (total change)/(number of shares)

change per share = (-40 dollars)/(10 shares) = -4 dollars/share

The change in value for each share was -4 dollars.

(b) As with most rate problems, the quantity is the product of rate and time.

growth = (7 members/week) × (49 weeks) = 7×49 members

growth = 343 members

The change in the club's size was +343 members.

Answer:

a) -4

b) +343

Step-by-step explanation:

a) 10 shares - loss $40

1 share --- ?

? = 40 / 10 = 4 decrease

b) each week 7 members increase for 49 weeks

so total increase = 7 * 49 = 343

Lines 3x-2y+7=0 and 6x+ay-18=0 is perpendicular. What is the value of a?

BlackZzzverrR [31]

Answer:

$\boxed{\sf a = 9 }$

Step-by-step explanation:

Two lines are given to us which are perpendicular to each other and we need to find out the value of a . The given equations are ,

$\sf\longrightarrow 3x - 2y +7=0$

$\sf\longrightarrow 6x +ay -18 = 0$

Step 1 : Convert the equations in slope intercept form of the line .

$\sf\longrightarrow y = \dfrac{3x}{2} +\dfrac{ 7 }{2}$

and ,

$\sf\longrightarrow y = -\dfrac{6x }{a}+\dfrac{18}{a}$

Step 2: Find the slope of the lines :-

Now we know that the product of slope of two perpendicular lines is -1. Therefore , from Slope Intercept Form of the line we can say that the slope of first line is ,

$\sf\longrightarrow Slope_1 = \dfrac{3}{2}$

And the slope of the second line is ,

$\sf\longrightarrow Slope_2 =\dfrac{-6}{a}$

Step 3: Multiply the slopes :-

$\sf\longrightarrow \dfrac{3}{2}\times \dfrac{-6}{a}= -1$

Multiply ,

$\sf\longrightarrow \dfrac{-9}{a}= -1$

Multiply both sides by a ,

$\sf\longrightarrow (-1)a = -9$

Divide both sides by -1 ,

$\sf\longrightarrow \boxed{\blue{\sf a = 9 }}$

Hence the value of a is 9 .

Given RS = 6, ST = 3, and SL = 4, find SM.

NemiM [27]

A² + b² = c²
3² + 4² = c²
9 + 16 = c²
C² = 25
C = 5
so
SM = 5

Glenn rolls a 6-sided die. What is the probability that he gets a number greater than 2 or an odd number?

Marysya12 [62]

Hello!

You can write down what the possible numbers their are

The numbers greater than 2 are 3, 4, 5, and 6

The numbers that are odd are 1, 3, and 5

List all the numbers out in a row

3, 4, 5, 6, 1, 3, 5,

Eliminate one of the numbers that repeat

3, 4, 5, 6, 1

You put the amount of answers of the total amount of outcomes

The answer is 5/6

Hope this helps!
