There are 205 total students in a school. 20% of the students are 5th
graders. How many students are 5th graders? *
Answers
Answer:
41 students
Step-by-step explanation:
We're trying to find what 20% of 205 is so:
We start by converting 20% to a fraction :
20% = 1/5
Then we have
20% of 205 = 1/5 x 205 = 1/5 x 205/1 = 205/5
Notice that 205 was rewritten as the fraction 205/1, and that to multiply two fractions together, you simply multiply the numerators and denominators.
In order to find the simplest form of 205/5 we cancel out the greatest common divisor of 205 and 5, which is 5:
205/5 = 41/1
So there are 41 5th graders
In 2019, there were about 21 million teenagers (aged 13-17) in the United States. They each sent an average of 3,300 text message per month. About how many text messages did all of the teenagers in the United States send each month? Express your answer using scientific notation.
Answers
Answer:
All of the teenagers in the United States sent about 69,300,000,000 text messages each month.
Step-by-step explanation:
Given that in 2019, there were about 21 million teenagers in the United States, and they each sent an average of 3,300 text messages per month, to determine about how many text messages did all of the teenagers in the United States send each month the following calculation should be done:
21,000,000 x 3,300 = X
69,300,000,000 = X
Therefore, all of the teenagers in the United States sent about 69,300,000,000 text messages each month.
6. You buy a pair of shoes that cost $120. You use your 20% off coupon and pay an 9% tax. What is your
total bill?
Answers
Answer:
$104.64
Step-by-step explanation:
Because coupons come before tax, we have to take away 20%, then add 9%
Step 1 : Find 20%
In order to find the percent of anything, all you have to do is multiply the percent (as a decimal) by your price
In this case, it's : 120 × 0.20
Using this expression, we find that 20% of $120 = $24
Step 2 : take away 20%
Coupons take away money from a full price, so we will take away $24 from $120, leaving us with $96
Step 3 : Find 9%
Now we multiply 0.09 (9%) by our new price (96)
96 × 0.09 = $8.64
Step 4 : Add 9%
Lastly, we use our coupon-added price (96) and add our tax (8.64)
96 + 8.64 = $104.64

Actually Welcome to the concept of Isosceles triangles.
They have two sides equal to each other, so we get as,
==> 3x + 3 = 2x + 8
==> 3x - 2x = 8-3
==> x = 5
hence the length of AC = 5 units.
Answer:
AC = 5
Step-by-step explanation:
here's your solution
=> This is a isosceles triangle
=> both sides are equal.
=> AB = CB
=> 3x + 3 = 2x + 8
=> 3x - 2x = 8 - 3
=> x = 5
so, AC = 5

La montaña más alta del mundo es Everest cuya altura es de 8.848m y la altura de la segunda montaña más alta es de 2hm 3dam y 7m menos ¿Cuantos metros de altura tiene la segunda montaña más alta del mundo
Answers
Answer:
La segunda montaña más alta del mundo tiene 8611 metros.
Step-by-step explanation:
La montaña más alta del mundo es Everest cuya altura es de 8.848m.
La altura de la segunda montaña más alta es de 2hm 3dam y 7m menos. Para calcular la altura que tiene la segunda montaña más alta del mundo, debes realizar primero un cambio de unidades sabiendo que
1 hm= 100 m1 dam= 10 mEntonces podes aplicar las siguientes reglas de tres simple:
Si 1 hm equivale a 100 m, 2 hm equivale a ¿Cuántos metros?
[tex]metros=\frac{2 hm*100 m}{1 hm}[/tex]
metros= 200
Si 1 dam equivale a 10 m, 3 dam equivale a ¿Cuántos metros?
[tex]metros=\frac{3 dam*10 m}{1 dam}[/tex]
metros= 30
Entonces, la altura de la segunda montaña más alta es de 200 m+30 m+ 7 m menos que el Everest. Esto es, 237 metros menos que la montaña más alta del mundo. Entonces:
8848 metros - 237 metros= 8611 metros
La segunda montaña más alta del mundo tiene 8611 metros.

Mrs perez drove at constant rate of speed she drove a total of 33.75 miles in 3/4 of hours what was the speed in miles per hour that mrs Perez traveled if this situation is represented by the equation d=rt
Answers
Answer:
Speed in miles per hour = 45 miles per hour
Step-by-step explanation:
Given:
Distance cover by Mrs Perez = 33.75 miles
Time taken by Mrs Perez = 3/4 hours = 0.75 hour
Find:
Speed in miles per hour
Computation:
Speed = Distance cover / Time taken
Speed in miles per hour = Distance cover by Mrs Perez / Time taken by Mrs Perez
Speed in miles per hour = 33.75 / 0.75
Speed in miles per hour = 45 miles per hour

a click beetle abruptly releases elastic energy stored in its body to launch itself into the air. the function h(t)=-16t^2+12t represents the height h (in feet) of the click beetle t seconds after launching. the height of a second click beetle t seconds after launching is shown in the graph. which click beetle went higher?
Answers
Answer:
The first click beetle reaches a maximum height of 2.25 feet. From the graph, you can see that the second click beetle reaches a maxium height of between 1.5 and 1.6 feet. So, the first click beetle went higher.
A beetle reaches a maximum height of 2.25 meters after 2,25 seconds
How to determine the maximum height?The function is given as:
h(t)=-16t^2+12t
Differentiate
h'(t)= -32t + 12
Set to 0
-32t + 12 = 0
Add 32t to both sides
32t = 12
Divide both sides by 32
t = 0.375
Substitute t = 0.375 in h(t)
h(0.375) = -16 * 0.375^2 + 12 * 0.375
Evaluate
h(0.375) = 2.25
The above means that a beetle reaches a maximum height of 2.25 meters after 2,25 seconds
