"<span>Bob spent twice as much as James, who spent four times as much as Nava"

Bob:     b</span>
James: j
Nava:   n

Bob spent twice as much as James:           b=2j
<span>James spent four times as much as Nava: j=4n</span>

<span>Bob and James together spent $180:        b+j=180
but we have:                                                b=2j
                 </span><span>                                                -------------------
</span>                                           <span>                          2j+j=180
</span>                                           <span>                           3j=180      >>      j=60$
</span>                                           <span>                                                      b=2j=120$</span>
Recall this: <span>j=4n >>>>    60=4n >>>>>n=15$</span>


SO far we calculated how much everyone spent

I hope that helps!

Let's say that Bob is x and James is y

x + y = 180
x = 2y

2y + y = 180
y = 60.
James spent 60 dollars.

Find the surface area of a cylinder with the height of 10 inches and a base diameter of 6 in ​
sweet-ann [11.9K]

Answer:

339.24

Step-by-step explanation:

To find the surface area, you will need to the the area of the base of the cylinder. To do that, use the formula A=pi (r)^2

The radius is half the diameter do r=3

3.14(3)^2 should give you about 28.27.

This is the area of the top and bottom of the cylinder.

Now, do 28.27x10=282.7 to find the height surface area.

282.7+28.27+28.27=Surface area.

SA= about 339.24

LoneWolves or anyone plz help me with this math question! I promise I'll mark u brainliest for the absolute right ANSWER
jeyben [28]

Answer:

8 ft^2

Step-by-step explanation:

\frac{h1}{2ft} =\frac{h2}{3ft} \\\\

area of ABC is:

A= \frac{(3ft)(h2)}{2}

area of ABC is 18 square ft, then

h2 = \frac{(area)(2)}{3ft} = \frac{(18 ft^2)(2)}{3ft} =12ft

now you can find h1 and the area for EFG

(08.01 mc) sue wants to know how many families in her small neighborhood of 50 homes would volunteer to help at a neighborhood a
Pani-rosa [81]

Answer:

Yes, this is a valid inference because she took a random sample of the neighborhood.

Step-by-step explanation:

As we can see, Sue's survey was perfectly random and without any prejudice.

18% of the families, according to her research, would volunteer at the shelter. According to her, 18% of the local households should be required to volunteer at the animal shelter.

Therefore, given that she chose a representative sample of the area, her conclusion is valid.

Jackson purchases a new car for $48,000. The car's value can be modeled by the
vekshin1

We have been given that Jackson purchases a new car for $48,000. The car's value can be modeled by the  following exponential function: y = 48000(0.76)^t where y represents the car's  value and t represents time in years. We are asked to find the decay rate as a percentage.

We know that an exponential decay function is in form y=a\cdot (1-r)^x, where,

y = Final value,

a = Initial value,

r = Decay rate in decimal form,

x = time.

Upon comparing our given function y = 48000(0.76)^t with standard decay function  y=a\cdot (1-r)^x, we can see that 1-r=0.76.

Let us solve for r.

1-1-r=0.76-1

-r=-0.24

r=0.24

Let us convert 0.24 into percentage.

0.24\times 100\%=24\%

Therefore, the decay rate is 24%.
