(a).
36 players = 100%
? = 10%
(36×10) / 100%
= 3.6 gloves for left hand players.
Explanation :- Object needs to be in full form whereas 3.6 would be written as only 3 gloves in full.
Ans: Yes. Total gloves were enough.
(b).
36player gloves = 100%
7 lefties = ?
=700/36 = 19.4%
=19.4444444 as recurring would be,
19 % (nearest to whole percent) DONE ✅.
There is a rope running from the
top of a flagpole to a hook in the
ground. The flagpole is 6 meters
high, and the hook is 8 meters
from its base. How long is the
rope?
Answer:
10 meters
Step-by-step explanation:
Use the Pythagorean Theorem for this one:
[tex]a^{2} + b^{2} = c^{2}[/tex]
If a = 6, b = 8, then:
[tex]a^{2} + b^{2} = c^{2}[/tex]
[tex]6^{2} + 8^{2} = c^{2}[/tex]
[tex]\sqrt{6^{2} + 8^{2}} = c[/tex]
[tex]\sqrt{36 + 64} = c[/tex]
[tex]\sqrt{100} = c[/tex]
[tex]10 = c[/tex]
[tex]c = 10[/tex]
According to the Pythagorean theorem, if the flagpole is 6 meters high and the hook is 8 meters from its base, the rope is 10 meters long.
Hope this helps!

Find the value of x that makes m || n
Answer:
x = 60
Step-by-step explanation:
if m and n are parallels, that means that x and 2x would be same side interior angles.
same side interior angles add up to 180
x + 2x = 180
3x = 180
x = 180/3
x = 60

Brandon enters bike races. He bikes 7 1/2 miles every 1/2 hour. complete the table to find out how far Brandon bikes for each time interval
Answer:
12. Since there is no table given I will assume that what you want me to do is to show that Unit rate of Brandon’s biking. SO here are the data that we need: => 8 and ½ miles = 8.5 miles => ½ hour = .5 hours or 30 minutes Now, let’s solve for the unit rate => SO in every 30 minutes he bikes around 8.5 miles => Since 1 hour is equals to 30 minutes, simply multiply 8.5 by 2 => 8.5 * 2 = 17miles => 17 miles / hour

A line has a slope of 6 and a y-intercept of 5. What is its equation in slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
The equation in slope-intercept form is y = 6x + 5
Step-by-step explanation:
The slope-intercept form of the linear equation is y = m x + b, where
m is the slopeb is the y-interceptLet us solve the question
∵ A line has a slope of 6
∵ m is the slope of the line
∴ m = 6
∵ The line has a y-intercept of 5
∵ b is the y-intercept
∴ b = 5
→ Substitute the values of m and b in the slope-intercept form
∵ y = m x + b
∴ y = 6x + 5
∴ The equation in slope-intercept form is y = 6x + 5

Answer:
The solution to the inequality is:
[tex]-1\le \:x\le \:3[/tex]
The line graph of the solution is also attached.
Step-by-step explanation:
Given the expression
[tex]4x-1\:\le \:5x\:\le \:3\left(x+2\right)[/tex]
solving the expression
[tex]4x-1\:\le \:5x\:\le \:3\left(x+2\right)[/tex]
[tex]\mathrm{If}\:a\le \:u\le \:b\:\mathrm{then}\:a\le \:u\quad \mathrm{and}\quad \:u\le \:b[/tex][tex]4x-1\le \:5x\quad \mathrm{and}\quad \:5x\le \:3\left(x+2\right)[/tex]
solving
[tex]4x-1\le \:5x[/tex]
Add 1 to both sides
[tex]4x-1+1\le \:5x+1[/tex]
Simplify
[tex]4x\le \:5x+1[/tex]
Subtract 5x from both sides
[tex]4x-5x\le \:5x+1-5x[/tex]
simplify
[tex]-x\le \:1[/tex]
Multiply both sides by -1 (reverse inequality)
[tex]\left(-x\right)\left(-1\right)\ge \:1\cdot \left(-1\right)[/tex]
Simplify
[tex]x\ge \:-1[/tex]
Similarly solving
[tex]5x\le \:3\left(x+2\right)[/tex]
Subtract 3x from both sides
[tex]5x-3x\le \:3x+6-3x[/tex]
Simplify
[tex]2x\le \:6[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}\le \frac{6}{2}[/tex]
Simplify
[tex]x\le \:3[/tex]
So combine the interval
[tex]x\ge \:-1\quad \mathrm{and}\quad \:x\le \:3[/tex]
Merge overlapping intervals
[tex]-1\le \:x\le \:3[/tex]
Therefore, the solution to the inequality is:
[tex]-1\le \:x\le \:3[/tex]
The line graph of the solution is also attached.

Carla believes that the number of hours of video games a student plays is predictive of the student's grade point average. Which value
represents a correlation coefficient that would strongly support Carla's belief?
Answer:
Negatively Correlated
Step-by-step explanation:
Number of video games played is likely to be negatively correlated to student's grade.
Negative correlation means that the variables deviate in opposite directions, one variable increase (decrease) & other variable decrease (increase).
As more video games played implies lower student grade, less video games played higher student grade. So, the variables are negatively correlated.
Whether the variables are strongly negatively correlated (correlation coefficient > 0.5) or weekly correlated (correlation coefficient < 0.5). It depends on how severely video games affect student's performance.

Need answer simplify -2/5+4/3=
Answer:
The answer should be 14/15.
Step-by-step explanation:
The answer is 14/15 because -2/5 and 4/3 with a common denominator turns into -6/15 and 20/15.
Then you add both of them together.
-6/15 + 20/15 = 14/15
is it possible to draw a triangle with numbers 5,6,11
Answer:
No
Step-by-step explanation:
Let's use the Pythagorean Theorem. For those of you that don't know, it is [tex]a^2 + b^2 = c^2\\[/tex].
11 is the bigger side in this case, so our formula would go like this: [tex]5^2 + 6^2 = 11^2\\[/tex].
We now calculate to see if this is true.
25 + 36 [tex]\neq[/tex] 121
Therefore, the answer is wrong.
Is (2,5) a solution to this system of equations?
3x + 2y = 16
x + 14y = 13
yes
no
answers for both boxes please
Step-by-step explanation:
4x + y = 6 => 8x + 2y = 12.
8x + 2y = 12
+ (-5x - 2y = -3)
=> 3x = 9, x = 3.
Therefore 4(3) + y = 6, 12 + y = 6, y = -6.
The solutions are x = 3 and y = -6.
