There are 35 red marbles, 8 blue marbles, and 7 green marbles in a bag. What is the theoretical probability of randomly drawing a red marble?

○ 35%
○ 25%
○ 42.9%
○ 70%
​

Answers

Answer 1

Answer:

70%

Step-by-step explanation: 35/50 equals 0.7

Answer 2

Answer:

70%

Step-by-step explanation:

The total number of marbles will be 35 + 8 + 7 = 50 marbles in total (all the colors added together). The probability of drawing a red marble will be the number of red marbles divided by the total marbles. This also fits the  probability formula of (desired outcomes)/(total number of outcomes. Thus, we have 35 red marbles and 50 marbles in total. So, we get 35/50, which is 70%.

Answers

Answer:

A. 13

Step-by-step explanation:

The non-vertex angles of a kite are always congruent. Therefore,

m<X = m<Z = 102°

Sum of all angels of a kite = 360°

Thus:

m<X + m<Y + m<Z + m<W = 360°

Substitute

102 + (5x - 4) + 102 + (7x + 4) = 360

102 + 5x - 4 + 102 + 7x + 4 = 360

Add like terms

204 + 12x = 360

12x = 360 - 204

12x = 156

x = 156/12

x = 13

5. Match each description with the correct equation below. Then solve the equation.
a) When 4.26 is added to a number, the sum is 17.04.
b) The product of 4.26 and a number is 17.04.
c) When a number is doubled and 4.26 is subtracted, the result is 17.04.

4.26n = 17.04 2n − 4.26 = 17.04 n + 4.26 = 17.04

Amanda is 160 cm tall. She is 10 cm taller than her younger sister Carl a. Which of the following equations can be used to find x? X + 10 = 160 X + 160 = 10 X - 10 = 160 x = 10 + 160 ​

Answers

Answer:

A. x + 10 = 160

Step-by-step explanation:

This is the correct choice since, we already know the height of Amanda and it gives us the difference between her sister and her height. We can formulate an expression.

x + 10 = 160

Solve.

160 - 10 = 150

x = 150

Thus, Carla is 150 centimeters tall.

Answers

Answer: -3

Step-by-step explanation: well there is a pretty easy explanation for this because what you pretty much do is you put the answer around by doing 5-2 and just put a negative since the smaller number is in the front.

The answer is… 2 - 5 = -3
This is simple math so regularly since you will get a negative if it is puted as 2 - 5. So you might as well do the simple math 2 - 5, than as soon as you get your answer than just put a negative sign since it isn’t in the basic number scale, but instead on the negative number scale.

1) Substitute d=100 into the equation and solve for s:

s=sqrt(9.81d)

s=sqrt(9.81(100))

s=sqrt(981)

s≈31.32

Therefore, the speed of the wave will be about 31.3 m/s

2) Substitute d=1000 into the equation and solve for s:

s=sqrt(9.81d)

s=sqrt(9.81(1000))

s=sqrt(9810)

s≈99.05

Therefore, the speed of the wave will be about 99 m/s

What value of X makes the equation true -7x - (-5-x) = -9(2x-1) -1

Answers

Answer:

x = 1/4

Step-by-step explanation:

-7x - (-5-x) = -9(2x-1) -1

-7x + 5 + x = -18x + 9 - 1

combine like terms:

-6x + 5 = -18x + 8

add 18x to each side of the equation:

12x + 5 = 8

subtract 5 from each side:

12x = 3

divide both sides by 12:

x = 3/12 = 1/4
