Suppose you deposit $12.50 into your savings account each week for 4 weeks and then withdraw $4.80 each week for the next two we
monitta

Answer:

The total change in the amount of money in my account is $ 9.60

Step-by-step explanation:

Given:

Amount of money deposited each week, A_{d}=\$12.50

Amount of money withdrawn each week, A_{w}=\$4.80

∴ Amount of money deposited in 4 weeks, A_{dT}=A_{d}\times 4=12.50\times 4 = \$50

∴ Amount of money withdrawn in 2 weeks, A_{wT}=A_{w}\times 4=4.80\times 2 = \$9.6

Now, amount of money left in the account is the difference of the two amounts.

So, amount left = A_{dT}-A_{wT}=50-9.6=\$40.4

Therefore, the total change in the amount of money in my account is given as:

Total change = Initial amount after 4 weeks - Final amount in the account.

Total change = $ 50 - $40.4 = $ 9.6

A certain corporation listed their sales in 100s as 1,700. What was their actual volume in thousands?
svp [43]

Answer: 170

Step-by-step explanation:

Based on the problem, you know that this corporation listed their sales in 100s as 1,700. This means that, to calculate their actual volume in thousands, you need to multiply 1,700 by 100 and divide the product by 1,000.

Let be "x" their actual volume in thousands.

Therefore, applying the corresponding procedure, you get that the value of "x" is the following:

x=\frac{(1,700)(100)}{(1,000)}\\\\x=\frac{170,000}{1,000}\\\\x=170

What is the equation of the line that passes through the point (9, 6) and is perpendicular to the line y = 3x - 5?
Ilia_Sergeevich [38]

Answer:

Step-by-step explanation:

y = 3x - 5

m₁ = 3

The required line is perpendicular to y = 3x - 5. Let the required line's slope be m₂

m₂ = -1/m₁

m₂ = -1/3

Point (9,6)

Equation of line: y - y₁ = m(x - x₁)

y - 6 = (-1/3)(x - 9)

y-6=\frac{-1}{3})x+\frac{1}{3}*9\\\\y-6=\frac{-1}{3}x+3\\\\y=\frac{-1}{3}x+3+6\\\\y=\frac{-1}{3}x+9\\

Someone please help need ASAP

The slope intercept form is given by
y = mx + c
where m is the slope and c is the y - intercept

That is
m =  \frac{3}{5}
c = 7
Hence the equation is
y =  \frac{3}{5} x + 7
