The area of a trapezoid is 864 cm. It has a height of 24 cm, and the length

Mathematics

Answer:=42 cm

Step-by-step explanation:

Strap=(a+b)*h/2    ( where a and b are trapezoid' s  bases and h is a height)

So   864=(30+b)*24/2

30+b=864*2/24

30+b=864/12

30+b=72

b=72-30

b=42 cm

Probability of pulling a green marble out of a bag of coloured marble is 2:5 if you were to pull coloured marbles out of the bag
Slav-nsk [51]

Answer: 171 green marbles

Step-by-step explanation: There are 7 total marbles so 100/7 equals 14.28

Then there is a 2 out of 7 total tries so  14.28 * 2 equals 28.57% chance to get a green marble.

600 * 0.2857 = 171.41 marbles but you cant get half a marble so 171 green marbles.

When CA= 3x-1 and SR=5x+4, what is CA?
avanturin [10]

Answer:

CA=17

Step-by-step explanation:

From given picture we see that A and C are the mid points of sides QR and QS respectively.

We know that line joining mid points of the two sides of triangle is always half of the length of the third side.

So that means:

2*CA=SR

2(3x-1)=5x+4

6x-2=5x+4

6x-5x=4+2

x=6

plug value of x into CA=3x-1

CA=3*6-1=18-1=17

Hence final answer is CA=17

You make a time capsule with your friends. Find the surface area of the shape pictured. Use 3.14 to approximate pi.
Orlov [11]

Answer: 1,475.8mm^{2}

Step-by-step explanation:

1. If you join the top part and the bottom part of the figure, you obtain a sphere. Then, you must apply the formula for calculate the surface area of a sphere:

SA_s=4r^{2}(3.14)

Where r is the radius (r=\frac{10mm}{2}=5mm)

2. Then:

SA_s=4(5mm)^{2}(3.14)=314mm^{2}

3. The formula for calculate the suface area of the red part, which is a cylinder, is:

SA_c=2(3.14)(r)(h)

Where h is the height (h=32mm)

4. Then:

SA_c=2(3.14)(5mm)(32mm)=1,004.8mm^{2}

5. So, the total surface area is:

SA_t=314mm^{2}+1,004.8mm^{2}=1,318.8mm^{2}
