Jamin wants to paint a wall in his bedroom. In order to know how much paint to buy, he first needs to know the approximate area.

There is a window in the middle of the wall, so he'll only need to paint the shaded part shown. How many square feet is just the window? [Note: The wall and window are both rectangular.]

For this case what is asked is to find the area of the window.
 The area of the window in this case is a rectangle.
 Therefore, the area is given by:
 A = (18 * (1/12)) * (2)
 A = 3 feet ^ 2
 Answer:
 
the window is:
 
A = 3 feet ^ 2

Answer:

The answer would be 3ft.

Step-by-step explanation:

The area of the whole thing is 48ft. To find the area of the window, we have to multiply the base of the window by the height of the window. We have to put 18in. into feet. 18in. = 1.5ft. Multiply 1.5 x 2 and you get 3ft.

Hope this helps. :')

Masha biked 20km 20 minutes faster than Dasha biked 20km. Find the speed of each cyclist if one biked 2km/h faster than the othe
motikmotik

Answer:

  • 12 km/h and 10 km/h

Step-by-step explanation:

Let the speed of Masha = s, speed of Dasha = d

  • Distance = 20 km
  • Time difference = 20 min = 1/3 hr
  • Speed difference  = 2 km/h

<u>As per above info we get following equations:</u>

  • s = d + 2
  • 20/s + 1/3 = 20/d

<u>Substitute s and solve for d:</u>

  • 20/(d + 2) + 1/3 = 20/d

<u>Get rid of fraction by multiplying all terms by 3d(d + 2):</u>

  • 60d + d(d + 2) = 60(d + 2)
  • 60d + d² + 2d = 60d + 120
  • d² + 2d = 120
  • d² + 2d + 1 = 121
  • (d + 1)² = 11²
  • d + 1 = 11
  • d = 10

<u>Find s:</u>

  • s = 10 + 2 = 12

<u>The answer is</u>

  • Masha's speed 12 km/h and Dasha's speed 10 km/h

In a circle, chords ST and RA intersect at Y such that SY is perpendicular to RY. The value of mSA + mRT is: a. 90º b. 180º c. 2
pshichka [43]

Answer:

a. 90º

Explanation:

The chords ST and RA intesect at Y, so that SY is now perpendicular to RY and they form an angle 90 degrees at that point. However angles mSA and mRT are both at the circumference of the circle(a chord is a line from point of a circle's circumference to the other) and are both 90 degrees because angle at the circumference is half of angle at the centre in same arc.
