Find the difference 7 7/8 - 3 1/4

Mathematics

That would be 4 and 5/8. Because you would find the common denominator which would be 8 and then take 2*4 and 2*1 and get 2/8 and then subtract 3 and 2/8 from 7 and 7/8 and get 4 and 5/8. I hope this helps you.

EastWind [94]

Answer:

Vertex (-2.5,-300)

Step-by-step explanation:

We are given with h(t)=-16 t^2 +80 t.  We are asked to find the vertex.

X-coordinate of vertex =\frac{-b}{2a}

Where 'a' is coefficient of t^{2} term

'b' is coefficient of 't' term.

From given function, a= -16

b=80

So,

x-coordinate of vertex =\frac{-80}{2(-16)}

                                =-2.5

y-coordinate of vertex =-16(-2.5)^{2} +80(-2.5)

Simplify it,

            =-100 -200

           = -300

So, vertex is at (-2.5, -300).

Answer:

  x = 40 1/2

Step-by-step explanation:

The hash marks tell you the triangles are similar and the smaller one is 1/2 the size of the  larger one. Then x is half the length of the corresponding segment marked 81.

  x = 81/2

  x = 40 1/2

___

You may have to write it as 81/2 or as 40.5. Sometimes the answer needs to be in a particular form.

Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirre
NeTakaya

Answer:

She caught 10 rabbits

Step-by-step explanation:

Given

Represent Rabbits with R; Squirrels with S and Deer with D

S = 3D

S = R - 5

S + R+ D = 10 +4D

Required

Determine the value of R

S + R+ D = 10 +4D

Solve for R

R = 10 + 4D - D - S

R = 10 + 3D - S

Recall that S = 3D

Substitute 3D for S

R = 10 + 3D - 3D

R = 10

Hence;

<em>She caught 10 rabbits</em>
