Varvara68 [4.7K]3 years ago
4 0

Answer:

   2/17

Step-by-step explanation:

We can use the slope formula when given two points

m = (y2 - y1)/ ( x2-x1)

    = ( -1- -3)/( 8 - -9)

    = ( -1+3)/( 8+9)

   2/17

Answer:

20) 8 years

21) Tori could paint the room alone for 3 hours, Sydney could paint the room alone for 5 hours.

Step-by-step explanation:

A = P ( 1 + r/n ) ^ nt.

8000 = 5000 ( 1 + 6%/4) ^ 4t

8000 = 5000 ( 1 + 0.06/4) ^4t

8000 = 5000 ( 1 + 0.015 ) ^ 4t

8000 = 5000 ( 1.015 ) ^ 4t

8000 / 5000 = ( 4.06 / 4 ) ^ 4t

8/5 = ( 203/200 ) ^ 4t

b = aᶜ ⇔ logₐb = c

Additive invers of -12 + 7
lorasvet [3.4K]

Answer:

The additive inverse of 7 is −7, because 7 + (−7) = 0; The additive inverse of −0.3 is 0.3, because −0.3 + 0.3 = 0.

I hope I'm right and good luck! :)

sergei caught 4 striped fish. each one weighed the same number of pounds. then he caught another fish that weighed 8 pounds. whi
Grace [21]

8 x 5 = 32 is the expression. Since Sergei caught 4 striped fish that all weigh the same, we know that we can multiple the weight of one fish by the amount of fish he caught.

Since he also caught another fish that would make the total of fish 5.

Assume that the flask shown in the diagram can be modeled as a combination of a sphere and a cylinder. Based on this assumption,
kompoz [17]

If the flask shown in the diagram can be modeled as a combination of a sphere and a cylinder, then its volume is

V_{flask}=V_{sphere}+V_{cylinder}.

Use following formulas to determine volumes of sphere and cylinder:

V_{sphere}=\dfrac{4}{3}\pi R^3,\\ \\V_{cylinder}=\pi r^2h,

wher R is sphere's radius, r - radius of cylinder's base and h - height of cylinder.

Then

  • V_{sphere}=\dfrac{4}{3}\pi R^3=\dfrac{4}{3}\pi \left(\dfrac{4.5}{2}\right)^3=\dfrac{4}{3}\pi \left(\dfrac{9}{4}\right)^3=\dfrac{243\pi}{16}\approx 47.71;
  • V_{cylinder}=\pi r^2h=\pi \cdot \left(\dfrac{1}{2}\right)^2\cdot 3=\dfrac{3\pi}{4}\approx 2.36;
  • V_{flask}=V_{sphere}+V_{cylinder}\approx 47.71+2.36=50.07.

Answer 1: correct choice is C.

If both the sphere and the cylinder are dilated by a scale factor of 2, then all dimensions of the sphere and the cylinder are dilated by a scale factor of 2. So

R'=2R, r'=2r, h'=2h.

Write the new fask volume:

V_{\text{new flask}}=V_{\text{new sphere}}+V_{\text{new cylinder}}=\dfrac{4}{3}\pi R'^3+\pi r'^2h'=\dfrac{4}{3}\pi (2R)^3+\pi (2r)^2\cdot 2h=\dfrac{4}{3}\pi 8R^3+\pi \cdot 4r^2\cdot 2h=8\left(\dfrac{4}{3}\pi R^3+\pi r^2h\right)=8V_{flask}.

Then

\dfrac{V_{\text{new flask}}}{V_{\text{flask}}} =\dfrac{8}{1}=8.

Answer 2: correct choice is D.
