Answer:
1/72
Step-by-step explanation:
P(2 on number cube) = 1/6
P(10 on the card) = 1/12
To get the probability of two events at the same time you multiply the probability of the events on their own
[tex]\frac{1}{6}\times\frac{1}{12} =\frac{1}{72}[/tex]
∴ P(2 on the number cube and 10 on the card) = [tex]\frac{1}{72}[/tex]

Answer:
84
Step-by-step explanation:
Multiples of 3 in this range: 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99, 102, 105
Multiples of 6 in this range: 66, 72, 78, 84, 90, 96, 102
Multiples of 7 in this range: 63, 70, 77, 84, 91, 98, 105
If we look at these multiples, we see that 84 is the only number to show up in every list. Meaning, the answer is 84.
For an upcoming school field trip, there must be one adult supervisor for every five children.
If the bus seats 40 people, how many children can go on the trip?
Answer: 32 Childrens maximum I think
Step-by-step explanation: I believe it is 32 because there will be 8 adults for every 32 children (ratio 1 adult:5 children) then convert the ratio to ?adult: availaible seats (40) so multiply by 8 since 5×8 equals 40 and 8×1 equals 8 but the adults have their spots too so 40-8=32

can somebody explain in the simplest way how to find the slope? :)
Answer:
4/3
Step-by-step explanation:
Slope is rise over run. So how far do you rise to get up to 3 from -1. Put that over the run, (once you go up that many how far do you run?) Put that as a fraction and simplify if needed.

Answer:
[tex]x>-1[/tex]
Step-by-step explanation:
We have the inequality:
[tex]-3x+3<6[/tex]
Subtract 3 from both sides:
[tex]-3x<3[/tex]
Divide both sides by -3. Since we are dividing by a negative, we must flip the inequality sign:
[tex]x>-1[/tex]
Hence, our solution is all numbers greater than -1.

How do you solve -4(x + 5) - 9 = -45
Answer:
x=4
Step-by-step explanation:
Add 99 to both sides.
-4(x+5)=-45+9−4(x+5)=−45+9
Simplify -45+9−45+9 to -36−36.
-4(x+5)=-36−4(x+5)=−36
Divide both sides by -4−4.
x+5=\frac{-36}{-4}x+5=
−4
−36
Two negatives make a positive.
x+5=\frac{36}{4}x+5=

36
Simplify \frac{36}{4}

to 99.
x+5=9x+5=9
Subtract 55 from both sides.
x=9-5x=9−5
Simplify 9-59−5 to 44.

- -4 (x + 5) - 9 = -45
Add 9 to both sides! This makes:
-4 (x + 5) - 9 + 9 = -45 + 9
Simplify!
-4(x + 5) = -36
Divide both sides by -4! This makes:
-4(x + 5) over -4 = -36/-4
Simplify!
x + 5 = 9
Subtract 5 from both sides! This makes:
x + 5 - 5 = 9 - 5
Simplify
x = 4
If x = 4..
-4 (4 + 5) - 9 = -45
-4(4 + 5) - 9
4(4 + 5) = 36
= -36 -9
Subtract the numbers: -36 -9 = -45!
= -45

Solve for x and/or y:
Answer:
C) x=35
Step-by-step explanation:
First, we know that the total amount of degrees in a rotation is 360. As the picture tells us, the opposite angles will be exactly the same. Taking this information, we can have the following equation:
4x + 2(3x+5) = 360
By now using our linear equation skills, we get:
10x+10=360
10x=350
x=35
The degree amount of x for c) is 35 degrees.
C. Since the angles form a linear pair, their sum equals 180.
So, 2x + 3x + 5 = 180
x=35
D. Since the angles are verticle, they equal each other.
So, 3x + 5 = 5x -57
x=31

A public swimming pool that holds 45,000 gallons of water is going to be drained for maintenance at a rate of 100 gallons per minute. The amount of water, w (in gallons), in the pool after t minutes is given by the function w = 45,000 – 100t. How many minutes will it take to empty the pool?
Answer:
450 minutes
Step-by-step explanation:
Given
w = 45000 - 100t
Required
Determine how long it'll take to empty the pool
Being empty means there's no water in the pool.
So, we have to set w to 0 to get the value of t
i.e w = 0
Substitute 0 for w in w = 45000 - 100t
0 = 45000 - 100t
Collect Like Terms
100t = 45000
Divide through by 100.
t = 450
Hence, it'll take 450 minutes to empty the pool

Mr. Walker gave his students a poem to memorize and present to the class. After the presentations, he gathered data about the time each of seven students spent memorizing their poem and the number of errors each made when presenting it to the class.
He used a graphing tool to display the data in a scatter plot, with x representing the minutes spent memorizing the poem and y representing the number of errors. Then he used the tool to find the equation of the line of best fit:
y = -0.118x + 14.327.
Based on the line of best fit, approximately how many minutes did a student spend memorizing the poem if the student made 12 errors when presenting it to the class?

Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.
How many miles does the second cyclist bike in 45 minutes?
Answer:
The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles
Step-by-step explanation:
The given parameters are;
The distance between the two cyclist when they begin biking away from each other = 7 miles
The first cyclist's speed = 12 miles per hour
The second cyclist's speed = 12 + b miles per hour
Therefore, we have;
The equation for distance covered, d = Speed × Time
The distance covered by the second cyclist in 45 minutes, [tex]d_{45 \ minutes}[/tex] is given as follows;
45 minutes = 3/4 hour
[tex]d_{45 \ minutes}[/tex] = (12 + b) × 3/4 = (3/4·b + 9) miles
The distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.
Answer:
The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles
Step-by-step explanation:
The given parameters are;The distance between the two cyclist when they begin biking away from each other = 7 milesThe first cyclist's speed = 12 miles per hourThe second cyclist's speed = 12 + b miles per hourTherefore, we have;The equation for distance covered, d = Speed × TimeThe distance covered by the second cyclist in 45 minutes, is given as follows;45 minutes = 3/4 hour = (12 + b) × 3/4 = (3/4·b + 9) milesThe distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.
