Answer:

Table C

Step-by-step explanation:

To find the constant of proportionality, you need to divide y by x

Table A has a constant of proportionality of $\frac{1}{3}$ which is 0.3333 repeating

Table B has a constant of proportionality of $\frac{3}{5}$ which is 0.6

Table C has a constant of proportionality of $\frac{3}{10}$  which is 0.3

Answer:

260 miles
$73.80

Step-by-step explanation:

The cost of each plan (y) is the sum of the initial fee and the product of the mileage charge and the number of miles (x).

First Plan: y = 40 +0.13x

Second Plan: y = 53 +0.08x

We can find when the costs are the same by solving this system of equations. A way to do that is to subtract the second equation from the first:

(y) -(y) = (40 +0.13x) -(53 +0.08x)

0 = -13 +0.05x

Multiplying by 20 gives ...

0 = -260 +x

Adding 260, we have ...

x = 260

The plans cost the same for 260 miles of driving.

The cost of the plans for that distance is ...

y = 40 +0.13x = 40 +0.13(260) = 40 +33.80

y = 73.80

The cost when the two plans cost the same is $73.80.

Write an equation for a line g(x) perpendicular to f(x) = 4x − 5 and passing through the point (4, 20). plz.....

cluponka [151]

The slopes of perpendicular lines are negative reciprocals.The slope of the given line is 4.The slope of the perpendicular is -1/4.
Now we need to find the equation of a line that has slope -1/4 and passes through the point (4, 20).
We use the point-slope form of the equation of a line, where m = slope, and the point is (x1, y1).
y - y1 = m(x - x1)
y - 20 = -1/4(x - 4)
-4y + 80 = x - 4
x + 4y = 84

A panda and a giraffe start moving towards each other when they are 300 feet apart. The panda is running at a speed of P feet pe

liq [111]

Answer:

(2P + G) feet/min

Step-by-step explanation:

Speed of the panda = P

Speed of the giraffe = P + G

Thus,

Speed of Panda + Speed of Giraffe = approaching time

= P + P + G

= 2P + G

Thus, The panda and the giraffe are approaching each other at a rate

of (2P + G) ft/min

Hope it helps :)

The probability of getting a head when a biased coin is tossed is . The coin is tossed three times. Find the following probabili

S_A_V [24]

Answer:

a) P(three tails) = $\frac{1}{8}$

b) P(two tails followed by one head) = $\frac{1}{8}$

Step-by-step explanation:

coin is tossed three times so, outcome is

HHH, TTT, HTH, THH, HHT, THT, TTH, HTT.

Hence sample space will be

S = {HHH, TTT, HTH, THH, HHT, THT, TTH, HTT}

chance of getting three tails is '1' i.e. TTT

hence,

P(three tails) = $\frac{1}{8}$

two tails followed by one head is TTH

so, chance of getting that outcome is also '1'

hence,

P(two tails followed by one head) = $\frac{1}{8}$
