Answer: Her unit rate is 42.5 m/min.

Step-by-step explanation:

Since we have given that

Distance she covered = 1700

Time taken = 40 minutes

So, we need to find the unit rate.

As we know that Speed=\dfrac{Distance}{Time}

Speed is given by

\dfrac{Distance}{Time}\\\\=\dfrac{1700}{40}\\\\=42.5\ m/min

Hence, her unit rate is 42.5 m/min.

R(4, 2) and S(10, 10) are the endpoints of a line segment. What is the midpoint M of that line segment?
bogdanovich [222]

M = (7,6)

Step-by-step explanation:

formula to find mindpoint is

(\frac{x2 + x1}{2} \frac{y2 + y1}{2} )

(4,2) = (x1, y1)

(10,10) = (x2,y2)

now substitute those into the formula!

\frac{10 + 4}{2} \frac{10 + 2}{2}

now solve for x & y !!

x =  \frac{10 + 4}{2}  =  \frac{14}{2}  = 7

y =  \frac{10 + 2}{2}  =  \frac{12}{2}  = 6

so now that we have solved for x & y put it in point form and your done !!

point for is (x,y)

and thanks why the Midpoint is (7,6)

What is side e<br><br>Angle d and angle f<br>Please let me know asap
irga5000 [103]

9514 1404 393

Answer:

  • e ≈ 9.608
  • D ≈ 46.5°
  • F ≈ 38.5°

Step-by-step explanation:

The only given angle is between the two given sides, so the Law of Cosines must be used to find the side opposite the angle. It tells you ...

  e² = d²+f² -2df·cos(E)

  e² = 7² +6² -2·7·6·cos(95°) ≈ 92.321082

  e ≈ 9.608

The remaining angles can be found from the law of sines.

  sin(D)/d = sin(E)/e

  D = arcsin(d/e·sin(E)) ≈ arcsin(7/9.608·sin(95°)) ≈ 46.5°

  F = 180° -95° -46.5° = 38.5°

X^(2)+x^(2)=128<br> or<br> x^2+x^2=128
Dvinal [7]

Answer:

Step-by-step explanation:

x^2 + x^2 = 128                 Normally you don't do this but rewrite the question

1x^2 + 1x^2 = 128

You actually do use 1 + 1 = 2 First time I've ever done that.

2x^2 = 128                         Divide by 2

2x^2/2 = 128 / 2

x^2 = 64                            Take the square root of both sides

sqrt(x^2)= sqrt(64)

x = 8

A right rectangular prism has a length of 2 1/4 cm, the width of 8 cm, and height of
Vikentia [17]

Answer:

Volume of the rectangular prism=369cm^3

Step-by-step explanation:

Length=2\frac{1}{4} =\frac{9}{4} cm\\\\Width=8cm\\\\Height=20\frac{1}{2} =\frac{41}{2}cm

Volume of a rectangular prism = Length*Width*Height

                             =\frac{9}{4}*8*\frac{41}{2}\\\\  =\frac{72}{4}*\frac{41}{2}  \\\\=18*20.5\\\\=369cm^3

The volume of the rectangular prism with the given dimensions is 369cm^3
