How long will this trip take? A bike 15 miles per hour on a biking trail to a trailhead 30 miles away.
Answers
Answer:
2 hours
Step-by-step explanation:
Distance = Rate * Time
If we replace these with the numbers in the problem and use "t" as the variable, it becomes:
30 miles = 15 mph * t
Now, to solve:
30 = 15t
divide both sides by 15
t = 2
add the units
time = 2 hours

Answer:
direct
Step-by-step explanation:
The standard form of an equation representing direct variation is
y = kx ← k is the constant of variation
The standard form of an equation representing inverse variation is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
y = - [tex]\frac{2}{5}[/tex] x ← represents direct variation with k = - [tex]\frac{2}{5}[/tex]

Answer:
x= 65 z= 38 y= 77
Step-by-step explanation:
x=65° (opposite angles are equal)
z= 180°-[71+71 (bc the other side is also equal to 71)]
z= 180°-142°=38°
y= 180 - [sum of angle x (65°) and angle z (38°)]
y= 180 - 103= 77°
to make sure ur answer is correct the sum of angle x, y and z MUST = 180
lets check:
65° + 38° + 77° = 180°

Answer:
b.
m<1 = 80 degrees because of the alternate angles rule.
m<2 = 100 degrees because angles on a straight line equals 180 degrees.
c.
m<1=75 degrees because again of the alternate angle rule.
m<2= 60 because that angle is equal to diagonally upper angle (I'll call it Z) and that angle would equal 60 because 180-120=60

Find the Y intercept
Please help!!!
Answers
Answer:
y - intercept = 8
Step-by-step explanation:
Given
y = (m - 2)(m - 4)
To find the y- intercept, let m = 0 in the equation and solve for y, that is
y = (0 - 2)(0 - 4)
= (- 2)(- 4)
= 8 ← y- intercept or in coordinate form as (0, 8 )

Answers
Given:
Secret number is more than 11 units away from 50.
To find:
The absolute- value inequality that gives the possible values of Mai's number.
Solution:
Let the secret number be x.
Secret number is more than 11 units away from 50. It may be less than 50 or more than 50.
Case 1: If x<50, then [tex]50-x>11[/tex]
Case 2: If x>50, then [tex]x-50>11[/tex]
It means the absolute difference between secret number and 50 is greater than 11.
[tex]|x-50|>11[/tex]
Therefore, the required inequality is [tex]|x-50|>11[/tex].

Answer: Slope is undefined. x=0
slope calculation: -3-4/0-0 = -7/0 and anything divided by 0 is undefined
the x value in the coordinates is 0 so it’s x=0 line.
vertical lines always have undefined slopes
Answer:
[tex]x=0[/tex]
Step-by-step explanation:
So first of all we need the slope of the line we are trying to findWe get the slope by using the following formula [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex] So when you have two pairs of points, it will be [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] so our points are; (0,4) the first point, so [tex]x_1=0,y_1=4[/tex] and(0.-3) the second point, so [tex]x_2=0,y_2=-3[/tex] Put this in our equation [tex]slope=\frac{(-3)-(4)}{(0)-(0)}=\frac{-7}{0}[/tex] Oh no, that can't be right, any number divided by zero is undefined, meaning can't be answered. So this line has no slope So how do we know the equation? Remember, (a) if the line is horizontal, then the slope is 0,(b) if the line is vertical then the slope is undefinedSo our line is vertical, meaning it is an equation of xIf it were horizontal it would be an equation of ySo vertical, it is [tex]x=??[/tex] How do we know what x equals? Just look at our points (0,4) and (0,-3)For both of them [tex]x=0[/tex] and this is our equation!Why has social media made a significant impact on influencing government

8^6 ÷ 4^3

So, 262,144 ÷ 64 = 4,096.
Done!
Answer:
2^12 = 4096
Step-by-step explanation:
Assuming that the problem is:
8^(6) / 4^(3)
1. Convert all numbers to the same base
In other words, rewrite the problem such that all the bases (the numbers under the exponent) are the same.
8 can be rewritten as 2^3
4 can be rewritten as 2^2
Hence the problem is:
((2^(3))^(6)) / ((2^(2))^(3))
2. Combine the exponents on the numerator and denominator
((2^(3))^(6)) / ((2^(2))^(3))
Simplify, remember an exponent to the power of another exponent is the same as multiplying the two exponents, applying this:
(2^(18)) / (2^(6))
3. Simplify the fraction and solve
(2^(18)) / (2^(6))
Dividing two exponents, with the same base is the same as subtracting the exponents, hence:
(2^(12))
= 4096
