The correct answer is 0.125. Each outcome is out of 8 possible outcomes. 1/8 = 0.125 . Therefore, 0.125 is your answer.
I'll solve 21, and you then should be able to solve the rest on your own!
Since ADC is 135, that means that that whole angle is 135 degrees. In addition, since angles ADB and BDC add up to ADC, we get ADB+BDC=ADC=135=11x+9+7x=18x+9. Subtracting 9 from both sides, we get 126=18x. Dividing both sides by 18, we get x=7. Plugging that into 11x+9=BDC, we get 11*7+9=77+9=86
Answer:
40
Step-by-step explanation:
I answered by simply looking at the equation
In this question you are finding the surface area. So first you need to classify what is the height length and width.
6 cm- width
4 cm- length
3 cm- height
Next you should draw a rectangular prism. Put the width, length and height in the according sides. After doing so you would see the faces would have the following dimensions: 24, 12 and 18. Multiply each dimension by two and you will get your surface area 108 cm squared.
OR use the following formula: A=2(wl+hl+hw)
Answer:
save $3.6, pay $14.4
Step-by-step explanation:
A cd costs $18
If there is a 20% discount, you only have to pay 80% of the original price.
This means you only have to pay (0.80 x $18=) $14.4 dollars, which means you saved ($18 - $14.4=) $3.6.
Or you could just do $18 x 0.20 = $3.6
