Round to the nearest hundredth 6.086
Answer:
6.09
Step-by-step explanation:
Since the 6 in the thousadths place is greater than five, you round up on the place value to the right of the 6 which is 8, so that 8 becomes 9.
Hence, 6.09

how many solutions does this system have
Answer:
A) exactly one solution
Step-by-step explanation:
if we set the y values equal we would get

-7= 5x
x=-7/5
Since we get an x value, the answer is that they have exactly one solution.
There are 8 green tokens in the bag . The ratio of green tokens to black tokens is 4 for every 1 find the number of black tokens in the bag
Answer:
the number of black tokens in the bag is 2
Step-by-step explanation:
The computation of the number of black tokens in the bag is as followS
Given that
There is 8 green tokens
and, the ratio of green tokens to black tokens is 4:1
So let us assume the black tokens be x
So,
[tex]\frac{8}{x} = \frac{4}{1}[/tex]
Now do the cross multiplication
x = 2 tokens
Hence, the number of black tokens in the bag is 2

Answer:
A van can carry 15 students and a bus can carry 21 students
Step-by-step explanation:
System of Equations
There are separate trips to the water park for which vans and buses were rented. Let's call the variables:
x = number of students that a van can carry
y = number of students that a bus can carry
6 vans and 8 buses were filled with 246 students. This leads to the equation:
6x + 8y = 246
Dividing by 2:
4x + 3y = 123 [1]
4 vans and 8 buses were filled with 228 students. Thus, we form the equation:
4x + 8y = 228 [2]
Subtracting [2] minus [1]:
5y = 228 - 123 = 105
Dividing by 5:
y = 105/5 = 21
y = 21
From [1]:
4x + 3*21 = 123
4x + 63 = 123
Subtracting 63:
4x = 60
Dividing by 4:
x = 60/4 = 15
x = 15
A van can carry 15 students and a bus can carry 21 students

Which equation finds m given E, and C
Answer:
C
Step-by-step explanation:
E=mc^2
To find m, isolate m from the rest of the variables, E and C. Since m and c^2 are being multiplied, use the inverse of multiplication, division, to undo the multiplication.
E/c^2 = m.

Evaluate 9 to the power of -1/2
Evaluate 9 to the power of -1/2
=> 0.05
The equivalent expression of ''9 to the power of -1/2'' would be 1/3.
Used the concept of the square root of a number that states that,
The square root of a number is the number that, when multiplied by itself, gives the original number.
Given that,
The expression is 9 to the power of -1/2.
Now, it can be written as,
9 to the power of -1/2
[tex]= 9^{- 1/2}[/tex]
[tex]= \dfrac{1}{9^{1/2} }[/tex]
[tex]= \dfrac{1}{(3^2)^{1/2} }[/tex]
[tex]= \dfrac{1}{3 }[/tex]
Therefore, the expression is written as 1/3.

The cylindrical part of a architectural column has a height of 325 cm and a diameter of 30 cm. Find the volume of the cylindrical part of the column. Use 3.14 for π and round your answer to the nearest cubic centimeter if needed.
Answer:
[tex]V=229612.5\ cm^3[/tex]
Step-by-step explanation:
Given that,
The height of a cylinder, h = 325 cm
Diameter, d = 30 cm
Radius, r = 15 cm
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2h[/tex]
Putting all the values,
[tex]V=3.14\times (15)^2\times 325\\\\V=229612.5\ cm^3[/tex]
So, the volume of the cylinder is [tex]229612.5\ cm^3[/tex].

4x + 8 = 32 i need help btw i am in middle school
Answer:
x=6
Step-by-step explanation:
to solve this equation, we need to isolate the variable (x).
to do this we must subtract both sides by 8.
doing this we get:
4x=24
now we need to divide both sides by 4:
x=6
that's the answer!
The function f(x) = 2x^2 + 3 represents the rate of a boat traveling with the current in miles per hour.The function g(x) = x+2 represents the time the boat traveled in hours. Solve (f x g) (2), and then interpret the answer (f x g)(2) = 15, the distance in miles the boat traveled
(F times G) (2) = 15, the distance in miles the boat traveled
(F time G) (2) = 15, the number of boats
(F times G) (2) = 44, the distance in miles the boat traveled
(F times G) (2) = 44, the number of boats
Answer:
Step-by-step explanation:
Answer:
The distance travelled by the B737-400 aircraft in 5 hours is 2,000 miles
Step-by-step explanation:
Average speed = 400 miles per hour
Distance = 400t
t= 5
Total distance = 400t at t hours
Total distance when t = 5 hours
Total distance travelled = 400t
= 400 × 5
= 2,000 miles
Total distance travelled = 2,000 miles
The distance travelled by the B737-400 aircraft in 5 hours is 2,000 miles
