Kayla has a bowl of beads that contains 42 yellow beads, 28 green beads, 12 white beads, and 18 red beads. She randomly draws a bead from the bowl.The probability of Kayla not drawing a yellow or a green bead is %. The probability of Kayla drawing a red or a green bead is %.

Answers

Answer 1

Answer: a) probability of she not drawing a yellow beads or green beads is probability of she drawing red or white. Red+ white = 30. There are total of 100 beads. That means that asked probability is:
30/100

b) its oposite that result from a) yellow beads + green beads = 70
probability is: 70/100

Answer 2

Answer:

Answer:

1. 30%

2.46%

Step-by-step explanation:

The probability of Kayla not drawing a yellow or a green bead is 30 %. The probability of Kayla drawing a red or a green bead is 46 %.

Correct for plato! :)

Answers

Answer:

The answer to your question is: the second option

Step-by-step explanation:

a) This is not the right answer, the sentence to this option could be: fourteen more than the quotient of five and a number is 23.

b) This is the right option, the sentence is given in the description.

c) This is not the right answer, the sentence to thi option could be: the quotient of fourteen plus a number and five is 23.

d) This is not the right answer, the sentence of this option could be: the quotient of five and the addition of a number and fourteen is 23.

Final answer:

The equation representing the given number sentence is x/5 + 14 = 23.

Explanation:

The number sentence is "Fourteen more than the quotient of a number and 5 is 23." To represent this as an equation, we need to translate the words into mathematical symbols. Let's say the number is represented by x. The quotient of a number and 5 is x/5. Fourteen more than x/5 is x/5 + 14. So, the equation representing the number sentence is x/5 + 14 = 23.

The perimeter of the scalene triangle is 54.6 cm.Which equation can be used to find the value of b if side a measures 8.7 cm?

8.7 + b = 54.6
17.4 + b = 54.6
26.1 + b = 54.6
34.8 + b = 54.6

Answers

the correct question is
The perimeter of the scalene triangle is $54.6$ cm.
Which equation can be used to find the value of b if side a measure $8.7$ cm and side c measure $26.1$ cm?

we know that
the perimeter of a triangle is equal to

$P=a+b+c \n P=54.6 cm$ equation 1

$P=a+b+c \n P=8.7+26.1+b$ equation 2

equate equation 1 and equation 2
$54.6=(8.7+26.1)+b \n 54.6=34.8+b$

therefore

the answer is the option D
$34.8 + b = 54.6$

Answer:The correct answer is :

34.8 + b = 54.6

Step-by-step explanation:

The perimeter of the scalene triangle = Sum of length of all sides

Given that perimeter of the scalene triangle = 54.6 cm

a = 8.7 cm , c = 26.1 cm

a + b + c= 54.6 cm

8.7 cm + b + 26.1 cm= 54.6 cm

34.8 cm+b = 54.6 cm

From the given options the correct answer is:

34.8 cm+b = 54.6 cm

I was walking to the store at the same time as my friend Angela. No matter what, She has always gotten there twice as fast as me. Half way to the store her friend picks her up on his scooter which was 10 times faster than me. She got there in 30 minutes. How long did it take for me to get there?

Answers

let's call your speed "a"

her walking speed is then "2a"

and her friend's scooter speed is 10 a

let's also call the distance you need to walk "d"

so the time (t)you need is:

d/t=a
t=d/a

and her time is:
t= $(d)/(2) /2a+ (d)/(2) /10a$
(half a distance with the speed of 2a and half a distance (d/2) with the distance of 10 a

now we count (we know that her time is 30 minutes)

30= $(d)/(4a)+(d)/(20a)$ //multiply by 20a

600a= $5d+d$
600a=6d/divide by 6
100a=d

Now, in order to calculate your time we need to calculate:

t=d/a

but we know how much is d now!
t= $(100a)/(a)$ =100

which means that you need 100 minutes, or 1 h 40 minutes!!!

Two boats on opposite banks of a river start moving towards each other. They first pass each other 1400 meters from one bank. They each continue to the opposite bank, immediately turn around and start back to the other bank. When they pass each other a second time, they are 600 meters from the other bank. We assume that each boat travels at a constant speed all along the journey. Find the width of the river?

Answers

assuming that the river doesn not move
if they kept a constand speed then they passes
the problem doesn't say how fast they were moving, but we can see that 1 boat is faster so

first pass
1400 meters from 1 bank
if they turn around they are 600 meters from the other bank
since they kept constant speed, they passed in the same place so
distance from bank1 to markx=1400
distance from bank2 to markx=600
distance from bank1 to bank2=600+1400
1400+600=total distance=2000 m
