how to round 10.71428571 by the nearest ten.
Answer:
Well if it is rounding to the nearest 10 it is 10
but if you meant round to the nearest 10th then it is 10.7
Step-by-step explanation:
For 10 you look at the ones place if it is 0-4 round down if it is 5-9 round up so for this number round down which is 10
FOr 10.7 look at the hundredths place if it is 0-4 round down if it is 5-9 round up so for this number round down which is 10.7
Hope this helps!

Step-by-step explanation:
hope you have a great day!
Answer:
x = 5
Step-by-step explanation:
minus 2 from both sides. so you get
10 = 2x.
divide by 2 on both sides to get
x = 5

Twinkle toes tony kick the football and it landed 100 feet from where he kicked it also reach a maximum height of 125 feet write an equation that models the path of the ball while it was in the air
Answer:
The equation that models the path of the ball is y = 5·x - 0.05·x²
Step-by-step explanation:
The given information are;
The distance the football landed from where it was kicked = 100 feet
The maximum height the football reached = 125 feet
The equation that models the path of the ball is that of the equation of parabola in vertex form, given as follows;
y = a·(x - h)² + k
Where;
(h, k) = The coordinate of the vertex (which is the coordinates of the highest point reached by the ball)
Therefore, taking the x-coordinate of the highest point reached by the ball as midpoint of the horizontal distance moved by the ball, we have;
The x-coordinate of the midpoint of the horizontal distance moved by the ball = (50, 0)
We have;
The coordinate of the highest point reached by the ball = (50, 125)
Therefore;
(h, k) = (50, 125)
Substituting the above values in the equation of the parabola gives;
y = a·(x - 50)² + 125
At x = 100, y = 0, which gives;
0 = a·(100 - 50)² + 125 = a·2500 + 125
0 = a·2500 + 125
a = -125/2500 = -0.05
Therefore, we have;
y = a·(x - h)² + k = y = -0.05 × (x - 50)² + 125 = -0.05·x² + 5·x - 125 + 125
y = -0.05·x² + 5·x - 125 + 125 = -0.05·x² + 5·x
y = -0.05·x² + 5·x
The equation that models the path of the ball is y = -0.05·x² + 5·x.
Given the system of equations below, Identify the number of solutions.
x + 9y = 1
2x + 18y = -16
Question 3 options:
No Solution
Infinitely Many Solutions
3 Solutions?
One Solution
Answer:
no solution
Step-by-step explanation:
u can see: 2x + 18y = -16
=> x + 9y = -8
but x + 9y =1
so it is unreasonable

At noon, a tank contained 5 in. of water. After several hours, it contained 4 in. of water. What is the percent decrease of water in the tank?
Answer:
20%
Step-by-step explanation:
4 is 80% of 5, so all we need to do is find out what percent is left after 80%, 20%, and then that would be how much it decreased

A canoe rental service charges a $20 transportation fee and $30 dollars an hour to rent a canoe. Write an equation representing the cost, y, of renting a canoe for x hours. What is the cost of renting the canoe for 6 hours?
Answer:
use slope intercept form to write the equation y=mx+b m (slope of the line) will be the hourly fee, and b (y-intercept) will be the one-time transportation fee.
y=30x+20
to find the cost of renting a canoe for 6 hours, plug 6 into the equation replacing x
y=(30×6)+20
y=180+20=$200
Sorry, I can't graph the line, but I would number the x-axis of the coordinate plane (graph) by 1s or 2s (for the hours), and the y-axis by 20s (for the cost

24-10b=9 what is the missing variable equal to
Answer:
b = 1.5
Step-by-step explanation:
Lets first set up the equation:
24 - 10b = 9
Okay now lets add 10b on both sides:
24 = 9 + 10b
Now let's subtract 9 from both sides so we can get the variable b by its self:
15 = 10b
Okay now we can divide each side by 10:
1.5 = b
Answer:
24-10(1.5)=9
b = 1.5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
b = 3 /2
Decimal Form:
b = 1.5
10(1.5) = 15
24 - 15 = 9

Segments AB and CD intersect to form an angle of 89 degrees as shown. What is the measure of <2
Answer:
180-89= 91
Step-by-step explanation:
Answer:
2 = 91
Step-by-step explanation:
Angle 2 and the 89 degree angle are supplementary (They both add up to 180) because they form a straight line. So, you would do as follows:
180 - 89 =
91
