The members of track team ran laps around their school. They ran a total of 4 1/2 miles, each lap 5/6 mile long. How many laps did they run?
Answers
Answer:
5.4 laps
Step-by-step explanation:
One lap = 5/6 miles
= 0.833miles (approximately)
If 0.833 miles = 1 lap
4.5 miles = ?
4.5/0.833 = 5.4 laps
Final answer:
To find the number of laps the track team ran, divide the total distance by the length of each lap. In this case, the team ran approximately 5.4 laps.
Explanation:
To find the number of laps the track team ran, we need to divide the total distance they ran by the length of each lap. The total distance they ran is 4 1/2 miles, which can be written as 9/2 miles. Each lap is 5/6 miles long.
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. So, to find the number of laps, we can multiply 9/2 by the reciprocal of 5/6: (9/2) x (6/5) = 54/10 = 5.4.
Therefore, the track team ran approximately 5.4 laps.
Find the percent of the number.

Explain your method.
Answers
Answer:
The answer would be 9
Step-by-step explanation:
Step 1: Our output value is 30.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$30=100\%$.
Step 4: Similarly, $x=30\%$.
Step 5: This results in a pair of simple equations:
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
Step 7: Again, the reciprocal of both sides gives
Therefore, 30% of 30 is 9
Answer:
30%of 30 is 9
Step-by-step explanation:
first you change 30% into a decimal (.30) by moving the decimal over to the left two times.
next you multiply 30* .30 ( i recommend you multiply it like this 30.00)
.30
next your first answer should be 900.00 . when you get this answer move the decimal over to the left two time again and your answer look like 9.0000
which is 9 as your final answer :).

What is the length of CD?
Round to one decimal place
please help me
Answers
To calculate the length of CD, additional information about the geometric figure is necessary. Meanwhile, for operations like addition or subtraction, results should be rounded to the same number of decimal places as the number with the least decimal places.
Explanation:The student's question seems to refer to the relationship between angles in a geometric figure and determining the length of a side, specifically the length of CD, within that figure. However, to provide a correct and precise length of CD, more information from the geometric figure or additional conditions are required, such as side lengths or other angle measurements. As the question stands, it lacks sufficient data to calculate the length of CD.
Regarding rounding, in general when you are performing mathematical operations like addition or subtraction, the result should be rounded to the same number of decimal places as the number with the least number of decimal places. For example, if you were to add 5.123 to 2.5, the result should be rounded to one decimal place, since 2.5 has only one decimal place. The correct sum would be 7.6.
Write an equation in slope-intercept form that goes through the point (5, -3) and is parallel to y = 3x - 1.
Answers
Answer:
[tex] y = 3x -18[/tex]
Step-by-step explanation:
For this case we have this point given (5,-3) and we want to create an slope intercept formula given by:
[tex] y = mx +b[/tex]
And this equation needs to be parallel to y= 3x-1 so then the slope needs to be equal m =3 and then we can use the point given to find the intercept b like this:
[tex] -3 = 3*5 +b [/tex]
[tex] b = 3-15=-18[/tex]
And the formula for the slope would be given by:
[tex] y = 3x -18[/tex]
Nine tokens are black on one side and white on the other. Initially, four tokens have the black side up (see the picture). In each turn you have to flip three tokens. What is the least number of turns you need to have all tokens showing the same color?
Answers
Answer:
2 Movements
Step-by-step explanation:
Let us name the tokens
B-For Black Tokens
W-For White Tokens
The initial arrangement is therefore given as:
B-B-B-B-W-W-W-W-W
Since we are allowed to flip three tiles in each turn
First movement: Flip two blacks and one white, we would have:
B-B-W-W-W-W-W-W-B
Second movement: Flip the three black tokens, this would give us:
W-W-W-W-W-W-W-W-W
Therefore, the least number of movements to have all tokens showing the same color is 2.

You are standing on top of a building looking down at your friend who is getting chased by a zombie. The building is 150 feet tall. When your friend looks up, the angle of elevation is 50°. When the zombie looks up at you, the angle of elevation is 25°.
Answers
Answer:
a) 125.86 feet
b) 321.68 feet
c) 195.82 feet
Step-by-step explanation:
a)
To find the distance from the friend to the build, we just need to use the tangent relation of his angle. The opposite side is the height of the building and the adjacent side is his distance to the building:
tangent(50) = height / distance
1.1918 = 150 / distance
distance = 150 / 1.1918 = 125.86 feet
b)
Similarly to letter a), we can use the tangent relation of the zombie's angle, where the opposite side is the height of the building and the adjacent side is his distance to the building:
tangent(25) = height / distance
0.4663 = 150 / distance
distance = 150 / 0.4663 = 321.68 feet
c)
To find the distance from the zombie to the friend, we just need to subtract the two distances:
Distance = 321.68 - 125.86 = 195.82 feet

how do you solve 7 exponent 0.8
Answers
Answer:
4.74; Explanation is as follows
Step-by-step explanation:
When you raise a number to a fractional power, it is the same as taking a root of that number. Here's what I mean:
We know that .8 is the same as 4/5, so 7^.8 power is the same as 7^4/5 power!
[tex]7^\frac{4}{5} =\sqrt[5]{7^4}[/tex]
The above equation is the same as 7 raised to the .8th power! Now to solve, we do the following:
[tex]=\sqrt[5]{7^4} \\=\sqrt[5]{7*7*7*7} \\= \sqrt[5]{2401} \\=4.74[/tex]
So that is how you raise 7 to the .8th power!
Bryan is planning to serve blueberries and cream. He has 3/4 of a bottle of cream. Each bowl should have 1/8
of a bottle of cream.
How many bowls of blueberries and cream can Bryan serve?
Answers
Answer:
3/4 divide by 1/8 is 6.
Bryan can serve 6 bowls of blue berries
Step-by-step explanation:
Final answer:
Bryan can serve 6 bowls of blueberries and cream.
Explanation:
To calculate the number of bowls Bryan can serve, first determine how many bowls can be served from 3/4 of a bottle of cream. Since each bowl requires 1/8 of a bottle of cream, divide 3/4 by 1/8. This division is equivalent to multiplying 3/4 by the reciprocal of 1/8, which is 8/1. Thus, (3/4) / (1/8) = (3/4) * (8/1) = 6. Therefore, Bryan can serve 6 bowls of blueberries and cream with 3/4 of a bottle of cream. This calculation ensures efficient use of resources, allowing Bryan to accurately plan the quantity of ingredients needed for serving a specific number of bowls.
A desk is on sale for $380, which is 20% off the original price. Which equation can be used to determine the
amount of money saved, s, in dollars, when purchasing this desk on sale?
A s= 0.2(380)
B
S = (380 = 0.8) - 380
Cs= (380 = 0.5) – 380
D
8 = (380 = 0.8)
Answers
Tthe correct answer is:
A) [tex]\( s = 0.2(380) \)[/tex]
To determine the amount of money saved when purchasing the desk on sale, you first need to find the original price of the desk before the discount.
Let's denote the original price of the desk as [tex]\( P \)[/tex].
Since the desk is on sale for 20% off, the sale price [tex]\( S \)[/tex] can be calculated as:
[tex]S=P-0.20\times P=0.80\times P[/tex]
Where:
- [tex]\( P - 0.20 \times P \)[/tex] represents the original price minus 20% of the original price.
-[tex]\( 0.80 \times P \)[/tex] represents 80% of the original price.
Now, to find the amount saved [tex](\( s \))[/tex], it's the difference between the original price [tex](\( P \))[/tex] and the sale price [tex](\( S \))[/tex]:
[tex]\[ s = P - S \][/tex]
Substituting the expression for [tex]\( S \)[/tex]:
[tex]\[ s = P - 0.80 \times P = 0.20 \times P \][/tex]
So, the equation that can be used to determine the amount of money saved, [tex]\( s \)[/tex], in dollars, when purchasing this desk on sale is:
[tex]\[ s = 0.20 \times P \][/tex]
Complete correct question:
A desk is on sale for $380, which is 20% off the original price. Which equation can be used to determine the
amount of money saved, s, in dollars, when purchasing this desk on sale?
A [tex]s= 0.2(380)[/tex]
B [tex]s= (380 = 0.8) - 380[/tex]
C [tex]s= (380 = 0.5) - 380[/tex]
D [tex]8 = (380 = 0.8)[/tex]
The equation that can be used to determine the amount of money saved when purchasing this desk on sale is:
[tex]\[ {\text{D) } s = (380 \times 0.8) - 380} \][/tex]
Hence the correct option is d.
To determine the amount of money saved (s) when purchasing the desk on sale, we need to calculate 20% of the original price.
The original price of the desk can be represented by x, and the sale price is $380.
We know that the sale price is 20% off the original price, so the equation representing the sale price is:
[tex]\[ \text{Sale price} = \text{Original price} - \text{Discount} \]\[ 380 = x - 0.2x \]\[ 380 = 0.8x \][/tex]
To find the amount saved, we subtract the sale price from the original price:
[tex]\[ s = x - 380 \]Now, let's solve for \( s \):\[ s = 0.8x - 380 \][/tex]
So, the equation that can be used to determine the amount of money saved when purchasing this desk on sale is:
[tex]\[ {\text{D) } s = (380 \times 0.8) - 380} \][/tex]
Hence the correct option is d.
A dart hits the board. What is the probability that it will hit in Region II, as a decimal to the nearest tenth?
A) type in your fraction from step 3
B) p(region ll)= _____ (decimal to the nearest tenth)
Answers
We have been given a graph of a board. We are asked to find the probability that dart will hit in region II.
The probability that dart will hit the region II will area of region II over area of board.
Let us find area of region II. We can see that one side of region II is 35 and other is 20.
[tex]\text{Area of Region II}=35\times 20[/tex]
[tex]\text{Area of Region II}=700[/tex]
Length of board would be [tex]35+15=50[/tex]
Width of board would be [tex]20+8=28[/tex]
[tex]\text{Area of board}=50\times 28[/tex]
[tex]\text{Area of board}=1400[/tex]
[tex]\text{Probability that dart will land in region II}=\frac{700}{1400}[/tex]
[tex]\text{Probability that dart will land in region II}=\frac{1}{2}[/tex]
[tex]\text{Probability that dart will land in region II}=0.5[/tex]
Therefore, the probability that dart will land in region II is 0.5.

So,the right answer is 3.

Hope it will help you
This is very basic, so it won't take long. First step in any algebraic question is to combine like terms, any term with alike variables or constants. So to begin with we need to combine the constants.
2n+1=7 To combine like terms, we need to move the 1 over to the seven by subtracting on both sides like a mirror.
2n+1-1=7-1
2n=6
Then, since it's 2n we need to divide by two to get n isolated.
2n/2=6/2
n=3
The final answer is n=3.

D. no x-intercepts
Answers
Answer:
i think D or B is the answer
Step-by-step explanation:
Answer:
B. 1 x-intercept
Step-by-step explanation:
We can use the discriminant expression, b²- 4ac, to answer this question.
In the equation y = 3x² + 6x + 3 we know that,
3 = a-value
6 = b-value
3 = c-value
Using this information, we can plug these numbers into the discriminant expression to find the discriminant.
6² - 4(3)(3) = 0
Because the value is equal to 0, we know there is 1 real solution and therefore there is 1 x-intercept.
