A European swallow flies about 12 meters in 1 second.
How many kilometers could it fly in 15 minutes?
It could fly |
Answers
Answer:
It could fly 10,8 kilometers.
Step-by-step explanation:
The European swallow fly speed is 12 meters per second.
We have to calculate how many kilometers it could fly in 15 minutes.
This can be calculated using the equivalent factors for each of the units:
- 1 km is equivalent to 1,000 meters.
- 1 minute is equivalent to 60 seconds.
We know that the distance travelled by the fly is the product of the speed and the time, so we have:
[tex]D=v\cdot t\\\\\\D=12\,\dfrac{m}{s}\cdot15\, min\\\\\\D=12\,\dfrac{m}{s}\cdot(\dfrac{1\,km}{1,000\,m})\cdot15\, min\cdot (\dfrac{60\,s}{1\,min})\\\\\\D=\dfrac{12\cdot 15\cdot 60}{1,000}\,km=\dfrac{10,800}{1,000}\,km\\\\\\D=10,8 \,km[/tex]

Answer:

x=2√2
y=2√2
Step-by-step explanation:
First triangle :
tanΦ=v/3√3
tan30=v/3√3
(√3)/3=v/(3√3)
Cross multiply
(√3)/3 x 3√3=v
(√3 x 3√3)/3=v
(3√9)/3=v
(3x3)/3=v
9/3=v
3=v
v=3
Sin30=v/u
0.5=3/u
Cross multiply
0.5xu=3
0.5u=3
Divide both sides by 0.5
0.5u/0.5=3/0.5
u=6
Second triangle :
sin45=x/4
Cross multiply
x=4 x sin45
x=4 x (√2)/2
x=2√2
Cos45=y/4
Cross multiply
4 x Cos45=y
4 x (√2)/2=y
(4√2)/2=y
2√2=y
y=2√2

Select the correct choice below and fill in any answer box to complete your choice. A. The mean cholesterol level is nothing. (Round to one decimal place as needed.) B. There is no mean score.
Answers
Answer:
The mean cholesterol levels
= 173873.7
Step-by-step explanation:
For The mean
The mean is going to be sum of the numbers divide by the number
Mean = (130130 +145145+ 215215 +170170+ 165165 +225225+ 240240 +185185+ 130130 +132132 )/10
Mean =1738737/10
= 173873.7
For Median
Wee arrange ascending order
130130, 130130, 132132, 145145, 165165, 170170, 185185, 215215, 225225, 240240
Median = (165165+170170)/2
Median = 335335/2
Median = 167667.5
Mode = 130130

How much money must be in each envelope for them to have the same amount of money? Write and solve an equation. Solve each of the following inequalities for the given variable. Represent your solutions algebraically and on a number line. Be sure to use a test point to check your solution region.
Answers
Answer:
The envelopes have to have $101 for them to have the same amount of money.
x=$101
Step-by-step explanation:
Olivia has eight envelopes labeled “x” and an additional $218, so we can write that she has this amount of money:
[tex]M_o=8x+218[/tex]
Jasmine has five envelopes labeled “x” and an additional $521. We can write the money that Jasmine has as:
[tex]M_j=5x+521[/tex]
If both have the same amount of money, we have:
[tex]M_o=M_j\\\\8x+218=5x+521\\\\8x-5x=521-218\\\\3x=303\\\\x=303/3=101[/tex]
The envelopes have to have $101 for them to have the same amount of money.

Answers
Answer:
Starting time: 1:37
Step-by-step explanation:
Instead of proof to solve the problem, let us prove that the starting time above is correct;
1. There are 60 minutes in an hour, so 60 - 37 = the minutes 'till 2:00, or 23 minutes
2. Knowing that the time the truck stopped driving through the neighborhood was 5 minutes past 2:00, the minute difference being 23 + 5, or 28 minutes

What the the Quotient 7/12 divided by 2/5
Answers
Answer:35/24
Step-by-step explanation:
7/12 ➗ 2/5
Next step we change divide sign to multiplication,with the numerator and denominator of the right hand fraction inverted
7/12 x 5/2
(7x5)/(12x2)
35/24
The quotient of 7/12 divided by 2/5 is 35/24.
To divide fractions, you need to multiply the first fraction by the reciprocal (or the multiplicative inverse) of the second fraction.
The reciprocal of a fraction is obtained by swapping the numerator and the denominator.
So, to find the quotient of 7/12 divided by 2/5, you multiply 7/12 by the reciprocal of 2/5, which is 5/2.
Here are the steps:
Write down the first fraction: 7/12
Write down the reciprocal of the second fraction: 5/2
Multiply the first fraction by the reciprocal: (7/12) x (5/2)
Multiply the numerators: 7 x 5 = 35
Multiply the denominators: 12 x 2 = 24
Simplify the fraction, if possible: 35/24
Therefore, the quotient of 7/12 divided by 2/5 is 35/24.

A flagpole casts a shadow that is 21m long when the angle between the suns ray and the ground is 48. Determine the height of the flagpole to the nearest metre
Answers
Answer:
23 m
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationships between angle functions and side measures in a right triangle. The geometry of this problem can be modeled as a right triangle with one leg (h) equal to the height of the pole, and one leg (21 m) that is the shadow length on the ground. The angle of the sun's rays is the angle opposite the h leg, so we can use ...
Tan = Opposite/Adjacent
tan(48°) = h/(21 m)
h = (21 m)tan(48°) ≈ 23.32 m
The height of the flagpole is about 23 meters.

$0.16
$0.20
$0.37
$2.70
Answers
Answer: $0.16
Step-by-step explanation:
Hi, to answer this question we simply have to divide the variable cost ($1,972.50) by the number of miles driven (the variable; 12,000 miles)
Mathematically speaking:
1,972.50 /12000 = 0.16
The cost per mile for Omar to operate his vehicle last year was $0.16

The fuel tank in a car holds 20 gallons of gasoline. The car has a fuel efficiency rating of 24 miles per gallon. If the gas tank is full when the family begins, and their destination is 1,600 miles away, what is the least number of times they will have to stop and fill the gas tank to get to their destination?
Answers
Answer:
3
Step-by-step explanation:
1600 miles × (1 gallon / 24 miles) = 66⅔ gallons
66⅔ gallons × (1 tank / 20 gallons) = 3⅓ tanks
Rounding up to the nearest integer, the family will need 4 tanks. Since they start with a full tank, they will need to stop at least 3 times.

Wilson’s class?
Answers
Answer:
10:9

First ratio is 5:4. 4 is equal to Henry class
If you múltiply the ratio by 2 you get
10:8, This ratio can be compared because now Henry class has 8
2(5:4)
10:8
8:9
Meaning that the answer is 10:9
The require ratio of number of students in Mr. Moore's class to Mr. Wilson's class is 10:9
What is Ratio?The ratio can be expression as how many times one number contain another number.
For example, If any bag contain 4 apples and 8 oranges then the ratio of apple to orange is 4:8 while the ratio of the orange to the apple is 8:2
How to find ratio?Consider M denote the number student present in the Mr. Moore's class
similarly H denote the number of student in miss Henry's class and W denote the number of student present in Mr. Wilson's class
then we have given that
M : H = 5 : 4 or
[tex]\frac{M}{H} = \frac{5}{4}[/tex]
Also we have H : W = 8 : 9
[tex]\frac{H}{W} = \frac{8}{9}[/tex]
Now multiply these two equations we have
[tex]\frac{M}{H}\times \frac{H}{W}=\frac{5}{4}\times\frac{8}{9}[/tex]
[tex]\frac{M}{W}= \frac{10}{9}[/tex]
The ratio of number of student in Mr. Moore's class to Mr. Wilson's class is 10:9
