Could someone please answer #35 for me
katrin2010 [14]

Answer:

408

Step-by-step explanation:

Volume = length times width times height

So in this situation we can see that 17 is the length, 8 is the width, and 6 is the height

Knowing this information we can continue

If you think of a regular cube, you can split it diagonally and then it would be 2 triangles

So we can split the width, in halve which would be 4 and then apply the formula 4*6*17 and when you solve that you get 408 Now we have to split that in halve because remember it is a triangle and a triangle is halve of a square. Halve of 408 is 204.

If we repeat that prosses for the other side we will also get 204. Now we add 204+204 to get our answer 408.

Sorry is this was a little confusing but that's the best I can explain it.

Hope that helped and have a great day!

How can u solve this by system of equations by elimination 4x-5y=6;2x+5y=-28
gayaneshka [121]

Answer:

x=17/3, y=10/3. (17/3, 10/3).

Step-by-step explanation:

4x-5y=6

2x+5y=-28

-----------------

4x-5y=6

-2(2x+5y)=-2(-28)

--------------------------

4x-5y=6

-4x-10y=56

------------------

-15y=-50

15y=50

y=50/15

y=10/3

4x-5(10/3)=6

4x-50/3=6

4x=6+50/3

4x=18/3+50/3

4x=68/3

x=(68/3)/4

x=(68/3)(1/4)=68/12=17/3

Write an exponential function y = abx for a graph that includes (–3, 16) and (–1, 4) f(x) = 2(0.5)x f(x) = 0.5(2)x f(x) = 4(0.3)
Arisa [49]

Answer: f(x)=2(0.5)^x

Step-by-step explanation:

Given, the exponential function y = ab^x for a graph that includes (–3, 16) and (–1, 4).

On putting these points, we will have

f(-3)=16=ab^{-3}\\\\ f(-1)=4=ab^{-1}

Now,

\dfrac{f(-3)}{f(-1)}=\dfrac{16}{4}=\dfrac{ab^{-3}}{ab^{-1}}\\\\\Rightarrow\ \dfrac{4}{1}=\dfrac{b^{-3}}{b^{-1}}\\\\\Rightarrow\ \dfrac{4}{1}=\dfrac{b}{b^3}=\dfrac{1}{b^2}\\\\\Rightarrow\ b^2=\dfrac{1}{4}\\\\\Rightarrow\ b=\pm\dfrac{1}{2}=\pm0.5

since the multiplicative factor cannot be negative, so b= 0.5.

At b= 0.5

4=a(0.5)^{-1}\\\\\Rightarrow\ 4=a(\dfrac{1}{2})^{-1}\\\\\Rightarrow\ 4=a(2)\\\\\Rightarrow \ a=2

So, the required function is f(x)=2(0.5)^x.

On August 1, the supplies account balance was $1,025. During August, supplies of $3,110 were purchased, and $1,324 of supplies w
vichka [17]

we are given

Account balance on 1 st August was $1,025

so,

BB=1025

During August, supplies of $3,110 were purchased

so,

purchase =3110

$1,324 of supplies were on hand as of August 31

so, EB=1324

Let's assume supplies expense for August  as X

so, we can use formula

BB+purchase-X=EB

now, we can plug values

we get

1025+3110-X=1324

now, we can solve for X

we get

X=2811

so,

The supplies expense for August is $2811.........Answer
