Answer:439.2$

Step-by-step explanation:

So first there are 52 people who use the cleaning service right? therefore lets do 52 people times the amount paid each month 12.20$ = 634.4$

16 members in the first week times 12.20 = 195.2$

so then subtract 634.4-195.2= your answer of 439.2 $ were collected the second week

Which logarithmic graph can be used to approximate the value of y in the equation 3y = 7?

notka56 [123]

We have that
3^y = 7
applying log both members
log(3^y)=log 7
y*log 3=log 7
y=log 7/log 3

using the logarithmic graph of y=log x

I graphically determine the values for x = 3 and x = 7

see the attached figure

for x=3
log 3=0.48

for x=7
log 7=0.85

therefore
y=log 7/log 3-----> y=0.85/0.48-----> y=1.77

the answer is
the approximate value of y is 1.77

Please help!!!!! I would really appreciate it!! :)

Klio2033 [76]

Answer:

First evaluate 4^t

put x= 1 in 4^x

It's 4^1 = 4 but f(x) = 8

So we need to multiply with 2

So it's A) 2.4^x

You have from 10 p.m. to 11:30 p.m. to do a project. a. At 11, what fraction of the time remains? b. At 11:20, what fraction of

EleoNora [17]

Answer:

a. $\frac{1}{3}$

b. $\frac{1}{9}$

Step-by-step explanation:

To solve it we must work in a single unit of time.

The unit we will use to solve it will be in minutes

So from 10 pm to 11 pm, it has been 1 hour (60 minutes) and from 11 pm to 11:30 pm has been half an hour (30 minutes)

Now the total minutes that have passed from 10 pm to 11:30 pm is

$60+30= 90$

A fraction tells us how many parts we have

In this case 90 minutes is what we want to divide:

a. At 11, what fraction of the time remains?

Let's think about it in the following way if 60 minutes have passed from 10 pm to 11 pm, at what fraction of 90 minutes does 60 minutes equal?

To solve it we use a simple rule of three

$90 \longrightarrow 1\\ 60\longrightarrow x \\ \\ x=\frac{(60)(1)}{90} \\ x=\frac{2}{3}$

This is the fraction of time that has past.

Now the fraction of time that remains is

$1-\frac{2}{3}=\frac{1}{3}$

b. At 11:20, what fraction of the time remains?

Let's think about it in the following way if 80 minutes have passed from 10 pm to 11:20 pm, at what fraction of 90 minutes does 80 minutes equal?

To solve it we use a simple rule of three

$90 \longrightarrow 1\\ 80\longrightarrow x \\ \\ x=\frac{(80)(1)}{90} \\ x=\frac{8}{9}$

This is the fraction of time that has past.

Now the fraction of time that remains is

$1-\frac{8}{9}=\frac{1}{9}$

What’s the value of r?

-BARSIC- [3]

Answer:

r = 4

Step-by-step explanation:

z ^ (7/10) * z^ ( 33/10)

We know that a^ b* a^c = a^(b+c)

z^ (7/10 +33/10)

z^ (40/10)

z^4

r = 4

What is the equation of the vertical line through (-8, 5)

oksian1 [2.3K]

Answer:

The equation of the vertical line passing through the point (-8, 5) will be:

$x=-8$

Step-by-step explanation:

As we have to determine the equations for the horizontal and vertical lines passing through the point (-8, 5).

To determine the equation for the vertical line passing through the point (-8, 5), we must observe that the vertical line will always have the same x-value regardless of y-values.

Therefore, the equation of the vertical line passing through the point (-8, 5) will be:

$x=-8$
