The surface area of the geometric shape is B. 840 cm².

Step-by-step explanation:

Step 1:

The given figure is made up of three rectangles and two triangles.

The surface area of the geometric shape is given by summing the individual surface areas.

The geometric shape's surface area = The sum of the individual surface areas.

Step 2:

The surface area of the rectangles is the multiplication of its length and width.

The surface area of the rectangle with length z and width x = (26)(10)= 260 cm^{2}.

The surface area of the rectangle with length y and width x = (24)(10)= 240 cm^{2}.

The surface area of the rectangle with length x and width x = (10)(10)= 100 cm^{2}.

Step 3:

The area of a triangle is half the product of its base length and height.

The surface area of a triangle with base y and height x= \frac{1}{2} (24)(10) = 120 cm^{2}.

They are two similar triangles so their areas are equal

Step 4:

The geometric shape's surface area = 160 + 240+100+120+120 = 840 cm^{2}.

So the surface area is option B. 840 cm².

Is .634 rational number
Ksivusya [100]
Yes 0.634 is a rational number.
Rational numbers are those numbers that can be still expressed in standard form or in fraction form and vice-versa. Unlike irrational numbers that are opposed to the definition of rational numbers. These values include pi, square root of two and etc. These values are impossible to fractionize. To better illustrate this circumstance.

We can have calculate a number that will have a quotient of 0.634 or a fraction that is equal to the given value. <span><span>

I need help with help on the one with the pink circle
podryga [215]

Answer:

15°

Step-by-step explanation:

The line in the middle of the triangle divides it into two triangles.  These two triangles are equal.  You can see this because the given angle (90°) is equal for both sides, and the bottom sides (23) are also equal to each other.  

Since the triangles are equal, this means that the given angle of 75° also applies to the other side.  The total degrees a triangle can have is 180°.  Use the given angles to solve for the unknown angle.

75° + 90° + x = 180°

165° + x = 180°

x = 15°

The angle measure will be 15°.

HELP ASAPPPP!!!!You are making a picture frame in the craft cabin at summer camp. The frame measures 9 inches by 12
Greeley [361]

Answer:

yes

Step-by-step explanation:

euhm ... did u just asked if a figure with h=9inches and b=12inches is rectangular???

Does it matter what the diagonals are etc?

if the frame has angles of 90° and it has two different lengths then it has to be rectangular. The sides of a square would have the same lengths.

Answer:

  • B. y = -4/3x + 22

Step-by-step explanation:

Parallel lines have the same slope.

<u>Use the given point (6, 14) and point-slope form:</u>

  • y - 14 = -4/3(x - 6)
  • y = -4/3x + 8 + 14
  • y = -4/3x + 22

Correct choice is B

PLZZZZZ HELP ME! :) XDDD
Taya2010 [7]
 In order to figure out what the answer is you would have to divide the number of feet it fell by the time. If you do 35.75 divided by 3.25 it would be 11. 
So the answer most likely would be 11
Please correct me if I am wrong
Have a great day!
