You roll a fair number cube and flip a coin at the same time. What is the probability that you roll a 5 and flip a heads?
Answer:
probably of a head= 1/2
probably of a multiple of 3 (either 3 or 6)= 2ways*1/6 as 1/6 is the prob of any one side
Step-by-step explanation:
Answer:
1/12 or 8.3%
Step-by-step explanation:
To find probability, mark the how many sides you are testing in your probability over the possible outcomes.
Die: 1 side out of 6 sides is the test = 1/6 probability abt. 16%
Coin: 1 side out of 2 sides is the test = 1/2 probability 50%
To find total probability of getting a 5 on the die and a heads on the coin is found by multiplying the two fractions together.
1/6 x 1/2 = 1/12
abt. 16% x 50% = abt. 8%
There are 160 boys and gitls playing in soccer tournament. 32 of the students are wearing Orange. What percent of yhe players are wearing orange
Answer:
20 percent
Step-by-step explanation:
Because there are 160 total people, you would divide 32 by 160 which gives you 0.2 multiply 0.2 by 100 then you get 20 percent
32/160 = 0.2
0.2*100 = 20
Answer:
53.3%
Step-by-step explanation:
(32/63)×100
=53.3%

Answer:
3 batches
Step-by-step explanation:
We have been given that a sports drink recipe calls for 5/3 tablespoons of powered drink mix for every 12 ounces of water.
We need to find out how many batches can be made with 5 tablespoons of drink mix and 36 ounces of water.
So, from the given information we see that to make 1 batch of sports drink we need 5/3 tablespoons of powdered drink mix for every 12 ounces of water.
So, we have 36 ounces of water. But we know that for 1 batch of sports drink we need to 12 ounces. So with 36 ounces of water we can make
= 3 batches
Therefore, we can make 3 batches of sports drink from 5 tablespoons of powdered drink mix and 36 ounces of water.

d=3 1/4
Step-by-step explanation:
Answer: 3 1/4 or 37/4
Step-by-step explanation:
3 1/4 would have an extra fraction, subtracting would make both sides equal. 37/4 is 3 1/4 as an improper fraction instead of a mixed number.

Find the x-intercept and the y-intercept.
Then use them to graph the line.
X-intercept:
X 미미
y-intercept:
Answer:
x=8
y= -6
Step-by-step explanation:
3(0)-4y=24
-4y=24
24÷-4
y = -6
----------------------
3x-4(0)=24
3x=24
24÷3
x = 8
to find the x-intercept, substitute the y for a zero "0", to find the y-intercept, substitute the x for a zero "0"

One standard size for the United States flag is 19 feet
by 10 feet.
What is the ratio of length to width for this flag?
Answer:
Answer:
19 : 10 = 19 : 10
Solution:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 19 and 10 is 1
Divide both terms by the GCF, 1:
19 ÷ 1 = 19
10 ÷ 1 = 10
The ratio 19 : 10 cannot be reduced further by dividing both terms by the GCF = 1 :
This ratio is already in lowest terms.
Therefore:
19 : 10 = 19 : 10
Step-by-step explanation:
What is the directrix of the parabola? (y+4)2=4(x−2)
Answer:
the answer is 1
Step-by-step explanation:
Answer:
x=1
Step-by-step explanation:
for y²=4ax
directrix is x=-a
for y²=4x ,directrix is x=-1
for y²=4(x-2), shift directrix 2 units right.
so directrix is x=-1+2=1
so for (y+4)²=4(x-2) directrix is x=1

Answer:
8. 504ft²
9. 4970yd² (rounded to 3 s.f.)
Formulas (For easy reference):
Area of rectangle = length × breadth
Area of circle = pi×r×r
Circumference of circle = pi×r×2
-----------------------------------------------------------------------------------------------------------
Step-by-step explanation:
8. You know a box has 6 sides, and there are 3 types of surfaces that are different from each other, and you have to multiply each side by 2 cus there are the front and backside (You can draw the box with its dimensions to see the 3 types of surfaces and why I multiplied by 2):
(2×12×6) + (2×12×10) + (2×6×10) = 144 + 240 + 120
= 504ft²
9. The net of a cylinder contains two circles of radius 24yd and one long sheet to wrap around the circles with the length that is the circumference of the circle (so that it can wrap around the two circles) and a width which is the height of the cylinder (9yd).
2 Circles = 2×pi×24×24
= 1152pi
Long sheet = 9×24×2×pi
= 432pi
Now we can add all of them together:
432pi+1152pi = 1584pi
= 4970yd² (rounded to 3 s.f.)
Answer:
Step-by-step explanation:
9.) Surface Area of Cylinders: A=2πrh+2πr^2
A=2πrh+2πr^2
A=2(3.14)(12)(9)+2(3.14)(12)^2
A = 678.24 + 904.32
A ≈ 1582.56
Two different buses start their routes at the same corner at 9 A.M. Buses from one route stop at the library every 9 minutes. Buses from the other route stop at the library every 12 minutes. In what number of minutes will both buses end up at the library?
Answer: In 36 minutes both buses will end up at the library.
Step-by-step explanation:
Given: Buses from one route stop at the library every 9 minutes.
Buses from the other route stop at the library every 12 minutes.
The number of minutes in which both buses will end up at the library= LCM(9,12)
Now , 9= 3 x 3
12= 2 x 2 x 3
LCM(9,12) = 2 x 2 x 3 x 3 = 36
In 36 minutes both buses will end up at the library.
Help me with this question
Answer:
Second choice, 4/3
Step-by-step explanation:
With the two point already highlighted, find the difference they have in x and y. (-1, 2) and (2, 2)
x = -1 - 2 = -3
y = -2 - 2 = -4
The slope is y/x so it would be -4/-3 or just 4/3 because the negatives cancel each other out and they mean the same anyway.
An easier way would to just draw a slope triangle from the two points and count the squares they have. 4 squares going up and 3 squares going to the right = 4/3
12. The point P lies on a line through the midpoint of AB and perpendicular to AB. If AP=15 in., what is the length PB? How do you know?
Answer:
PB = 15
Step-by-step explanation:
A midpoint is a point in the center of a line. Since P is the midpoint of AB, the length of AP = PB. Therefore, if AP = 15, PB = 15.

Answer:
3
Step-by-step explanation:
Dilated has the meaning of getting larger. So in this case, if it has any meaning at all and the answer is "no answer given" then all you have to do is look at the y intercept.
The shorter line has a y intercept of 1
The longer line has a y intercept of 3
Therefore the dilation factor is 3
However if your teacher is a stickler for a better proof, then you could compare lengths.
Shorter line
Two end points
(-6,-3) (6,5)
Distance = sqrt( (-6-6)^2 + (-3-5)^2 )
distance = sqrt (144 + 64)
distance = sqrt(208)
distance = 14.42
Longer line
(-12,-5) (24,19)
distance = sqrt(24 - - 12)^2 + (19 - -5)^2 )
distance = sqrt( 36^2 + 24^2)
distance = sqrt (1296 + 576)
distance = sqrt(1872)
distance = 43.27
The best answer is =3

Mr. B traveled 500 miles in his car in 5 hours. How fast was he going?
Answer:
100 miles per hour.
Step-by-step explanation:
To solve this we need to divide 5 by 5 to find the answer for 1 hour rather than 5.
5 / 5 = 1
Following the logic of, “what you do to one side, you must do to the other” i will divide 500 by 5.
500 / 5 = 100
Mr B was traveling at 100 miles per hour.
