A plane goes from a standstill to 350 mi/hr in about 45 sec. What is the plane's acceleration?
Answer:
The acceleration is 466.7m/s^2
Step-by-step explanation:
Given
[tex]u = 0m/s[/tex] -- Initial Velocity
It is 0 because the plane starts from a standstill
[tex]v = 350mi/h[/tex] -- final velocity
[tex]t = 45s[/tex] -- time
Required
Determine the acceleration
This is calculated using Newton's first equation of motion
[tex]v = u + at[/tex]
Convert time to hour
[tex]t = 45s[/tex]
[tex]t = \frac{45}{60}hr[/tex]
[tex]t = 0.75hr[/tex]
Substitute values for v, u and t
[tex]350 = 0 + a*0.75[/tex]
[tex]350 = 0.75a[/tex]
Divide both sides by 0.75
[tex]\frac{350}{0.75} = a[/tex]
[tex]466.67 = a[/tex]
[tex]a=466.67m/s^2[/tex]
Hence, the acceleration is 466.7m/s^2
Find exact radius of circle please help!
===========================================================
Explanation:
Let r be the radius we want to find
The area of the full circle is A = pi*r^2
The unshaded portion is 60 degrees, so the unshaded portion must be 360-60 = 300 degrees.
The full area was pi*r^2, but we only want 300/360 of that full area.
So,
s = shaded area
s = (300/360)*(full circle area)
s = (300/360)*(pi*r^2)
s = 30pi
(300/360)*(pi*r^2) = 30pi
(300/360)*r^2 = 30
(5/6)*r^2 = 30
5r^2 = 30*6
5r^2 = 180
r^2 = 36
r = sqrt(36)
r = 6
The radius is 6 inches.
Solve this system by substitution, y = 4x + 12. -3x + 2y = 4
Step-by-step explanation:
in equation 1
y=4x+12
so now
eqs 2
2y=4+3x
then
-y=x+8
y= -x-8
so
-x-8=4x+12
-20=5x
-4=x
so
y= 4-8
y=-4

Answer:
1.2
Step-by-step explanation:
4 3/20 as a fraction
Answer: 83/20
Step-by-step explanation:
Take a mixed number (whole number with a fraction) and turn it into an improper fraction (numerator is more than the denominator)
To do this, multiply the denominator (20) by the whole number (4) and add the numerator (3) to it. 20x4+3= 83. This is your new numerator. Now just simply write this over the original denominator of 20. = 83/20

-4x< 8 help please solving one step inequalities
Answer:
x>-2
Step-by-step explanation:
when dividing by a negative number, the inequality sign flips.
Answer:
x > -2
Step-by-step explanation:
-4x< 8 (divide both sides by -4)
-x < 8/4
-x < 2 (divide or multiply both sides by -1, remember to flip the inequality when multiplying or dividing by -1)
x > 2 (-1)
x > -2

Find all real zeros of the function y=-9x-1
A. -9
B. 1/-9
C. 1/9
D. -9 -1
Please select the best answer from the choices proided
Answer:
OPTION D
Explanation:
For zeros of the function (y is the function, a function of x) we need y = 0 so that in turn means we need - 9x - 1 = 0 or - 9x = 1 (i.e. add 1 to both sides); now divide by - 9, and x = 1/-9 which is exactly the same as - 1/9 or - (1/9) and this is the only zero of the function.
or
If y = -9x - 1,
When y = 0
0 = -9x - 1
0 + 1 = -9x - 1 + 1
1 = -9x
1/9 = -9x/9
1/9 = -x
1/[9 X (-1)] = -x/-1
- (1/9) = x
When x = 0
y = (-9 X 0) - 1
y = 0 - 1
y = - 1

What are the partial products for 3.2 x 0.6?
Answer:
This is a complete lesson with instruction & exercises for 5th grade about multiplying decimals by decimals. The interpretation for multiplying a decimal by a decimal is to think of it as taking a fractional part of a decimal number (the symbol × translates to "of"). The lesson compares multiplication by a decimal to scaling & shrinking a stick. Lastly, it shows the common shortcut to decimal multiplication (multiply as if there were no decimal points; the answer has as many decimals as the factors have in total.)
In the video below, I explain the rule for multiplying decimals (put as many decimal digits in the answer as there are in the factors.) I explain where this rule comes from, using fraction multiplication. The lesson continues below the video.
Obtuse triangles have only one obtuse angle.
True or false
Answer: true
Step-by-step explanation:
Answer:
yes, obtuse angles have only one obtuse angle.
hence, it's true.
Step-by-step explanation:
A triangle can't have more than one obtuse angle , because if there are more than one obtuse angle the sum of measures of all interior angles will exceed 180°, which isn't possible.

What is the solution to the system?
1/2x + 3/2= -7
-3x + 2y = -2
Answer: (-2, -4)
Answer:
the (x, y) pair solution to the system is: (-2, -4)
That is x = -2 and y = -4
Step-by-step explanation:
I presume there is a variable y missing in the first equation, and in fact the system looks like:
(1/2) x + (3/2) y = - 7
- 3 x + 2 y = -2
In such case, we proceed to multiply both sides of tye first equation by 6
6 (1/2) x + 6 (3/2) y = - 42
3 x + 9 y = - 42 and we add term by term this equation to the second one, so as to cancel out the term in x:
3 x + 9 y = - 42
- 3 x + 2 y = -2
_____________
11 y = - 44
divide both sides by 11 to isolate y
y = -44 / 11 = -4
Then with the value y = -4, now we replace it in the second equation to solve for x:
- 3 x + 2 y = - 2
- 3 x + 2 (- 4) = -2
- 3 x - 8 = - 2
add 8 to both sides
- 3 x = 6
divide both sides by (-3) to isolate x
x = 6 / (-3) = - 2
Therefore the (x, y) pair solution to the system is: (-2, -4)
That is x = -2 and y = -4

Step-by-step explanation:
simplify (5 square root 2) * ( 3 square root 2 )
Answer:
30
Step-by-step explanation:
multiply 5 x 3 and you get 15 then multiply the roots and you also get 2 so then you have to multiply 5 and 2 to get 30.
The solution is : the simplification of 5√2 × 3 √2 is: 30.
Here, we have,
given that,
5√2 × 3 √2
now, we need to simplify this, i.e. we have to multiply this.
so, we get,
multiply 5 x 3 and we get 15
then multiply the roots and we also get 2
i.e. √2 ×√2 = 2
so then you have to multiply 15 and 2 to get 30.
i.e. 15 * 2 = 30
so, we have,
5√2 × 3 √2
= 5 × 3 × √2 ×√2
=15 × 2
=30
Hence, The solution is: the simplification of 5√2 × 3 √2 is: 30.
