Answer:

Store B

Step-by-step explanation:

Since the lowest common multiple of 2 and 3 is 6, so let's find the cost of 6 bags of chips from each store.

Store A

cost for 6 bags of chips

= 3(2.5)

= $7.50

Store B

cost for 6 bags of chips

= 2(3.25)

= $6.50

Since store B offers a cheaper price for 6 bags of chips, it offers a better deal.

Alternatively, you could work out the cost of each bag of chips for both stores.

You answer is: 28 + 3[tex]x[/tex]

Since $28 is a one-time fee and does not have to be paid again for each and every ride, it does not need a variable in front of.

But for every ride you want, you pay $3 so you need the variable "[tex]x[/tex]" which represents how many times you ride.

For example, if you ride the roller coaster once, your total amount, in dollars, will be:

T = 28 + 3 * (1)

T = $31

But if you ride the roller coaster 3 times, your cost, in dollars, will be:

T = 28 + 3 * (3)

T = 28 + 9

T = $37

Answer:

Since the moon has no atmosphere, all wavelengths of sunlight reach the ground by traveling straight through space. Our sun appears white because it produces all visible wavelengths approximately equally. The sun will appear the same size whether viewed from Earth or the Moon since Earth and the moon are relatively close to the sun. The sun and moon both have an apparent size of one-half of a degree when viewed from Earth.

Trip of 45miles with seven gallons of gas in a car and car gets 22 miles per gallon ,estimate fuel supply for trip is 2 gallons.

As given in the question,

Total distance covered in family trip is 45 miles

Total fuel in car is seven gallons

Average of the on trip=22 miles per gallon

Estimate fuel supply for trip =(45 miles )/(22 miles per gallon)

                                               =2.04545gallons

                                               ≈2gallons(approximately)

As the fuel used in the trip is 2.04545.. gallons which is nearest to the 2 gallons, it is okay to estimate the fuel supply.

Therefore, trip of 45 miles with 7gallons of gas in a car with average 22 miles per gallon ,estimate fuel supply for trip is 2 gallons.

Answer:The time of Trip 2 is

⇒ 0.8 hours.

The distance of Trip 1 is

⇒ 4 km.

The time of Trip 2 is 0.8 hours

The distance of trip 1 is 32 km

Given,

The speed of the bus = 40 km/h

Talia's walked at a speed = 5 km/h

To determine the time,x for her walk here used the equation; 40(0.9 – x) = 5x.

We have to find the time from Talia's home to bank in bus and the distance.

Here,

Equation is already given, we can simplify it and get x which is the time.

40(0.9 – x) = 5x.

36 - 40x = 5x

36 = 40x + 5x

36 = 45x

x = 36/45

x = 0.8 hours = 0.8 x 60 = 48 minutes

Now,

Distance from Talia's home to bank;

Speed = distance/time

Distance = speed x time = 40 x 0.8 = 32 km

That is,

The time of Trip 2 is 0.8 hours

The distance of trip 1 is 32 km

Step-by-step explanation:

The percent by which the value of Ken's bike depreciated over the past year is 20%.

Depreciation is the decline in the value of an asset with the passage of time. Depreciation is as a result of wear and tear of an asset. The price of an item would decline when it depreciates.

Percentage is the fraction of an amount that is expressed as a number out of hundred. Percentage is used to measure the frequency of data. The sign that represents percentage is %. To convert a number to percentage, multiply the number by 100.

Percent depreciation = (value of the mountain bike today / value of the mountain bike last year) - 1

($320 / $400) - 1 = -0.20

0.20 x 100 = 20%

Answer:

20

Step-by-step explanation

We need to find the multiples of 10 and 20 (multiples of 10 = 10, 20, 30, 40; multiples of 20 = 20, 40, 60, 80) and choose the smallest multiple that is exactly divisible by 10 and 20, i.e., 20.

Answer:

20

Step-by-step explanation:

First, find the factors of both 10 and 20

Factors of 10: 1, 2, 5, 10

Factors of 20: 1, 2, 4, 5, 10, 20

Notice any common factors?: 1, 2, 5, 10

Now multiply the greatest common factor, 10, with another even number to hopefully get 20: 10*2=20.

Hence, the least common multiple is 20.

Step-by-step explanation:

did you change the reference number ?

I think the original question was "90 is how many % of 80 ?"

now it is 81.

in % calculations the most important things to identify :

what are 100% (or any other reference % level).

then what is 1%.

and then multiply this 1% by the desired number of % or divide the target number by this 1% to find out how many % the target number is.

in our case here

100% = 81

1% = 100%/100 = 81/100 = 0.81

how many % are 90 ?

well, as many as how often 1% fits into these 90 :

90/0.81 = 111.111111111... %

when the reference was 80, then we had

90/0.8 = 112.5%

15 km of walkway still need to be paved after 4 days. There are still 12 miles of trail to be paved after another 6 days. The average rate of the change is 24.

Given that,

The paving of a bike route by a city. Every day, the same amount of the path is paved. 15 km of walkway still need to be paved after 4 days. There are still 12 miles of trail to be paved after another 6 days.

We have to find the average change rate.

1st we find the slope with the points (4,15) and (6,12).

Slope =[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Slope=[tex]\frac{12-15}{6-2}[/tex]

Slope=-3/4

Now,

y=mx+b

15=-3/4(4)+b

b=15+3

b=18

We got the equation of line as y=-3/4x+18

Now take y=0

0=-3/4x+18

-3/4x=-18

x=(18×4)/3

x=72/3

x=24

If Lisa and Joey put the same amount of money every month in the savings account for David's future and the situation is plotted in a graph where time is on the x-axis, then there will be straight line with a constant slope.

As per the question statement, Lisa and Joey just became parents to their son, David and they decided to start a savings account for their newborn's future, where they agreed to put an equal amount of money every month.

We are required to determine the condition of the variables if the above-mentioned situation is plotted into graph and the account gets constantly filled with money as David grows older.

To solve this question, first let us consider the time to be plotted on the X-axis (As mentioned in question statement that "Time" is almost always on the x-axis) and the money collected to be plotted on the Y-axis.

Since, an equal amount of money is put into the account every month, therefore, taking 1 month as unit time to plot our graph, the money will grow diagonally in a straight line with a constant slope. Hence, both the variables (abscissa and ordinates) will increase on a constant ratio along the first quadrant.

The rate of change of an edge of the cube is 0.074 m/min.

The rate at which the volume of the cube changes is calculated as follows;

dv/dt = 2 m³/min

where;

The length of edge of the cube will be denoted with a, and it is related to the volume of cube in the following equation.

v = a³

a = v^¹/₃

where;

The change in the edge with volume;

da/dv = 1/3 (1/v)^2/3

The change in edge of the cube with time is given as;

da/dt = da/dv . dv/dt

da/dt = 1/3 (1/v)^2/3    x   2 m³/min

da/dt = 1/3 (1/27)^2/3 /m²     x    2 m³/min

da/dt = 1/27 x 2 m/min

da/dt = 2/27 m/min

da/dt = 0.074 m/min
