Step-by-step explanation:

The ratio formula is given as a:b = a/b for any two quantities, let's say a and b. Given that a and b are separate amounts for two quantities, the combined total quantity is denoted by (a + b).

There are 48 lollipops and 6 candy bars for a gift bag.

Then the possible ratios of lollipops to candy bars are:

( 48 / 6 ) ÷ ( 2 / 2) = ( 24 / 3 )

( 48 / 6 ) ÷ ( 3 / 3) = ( 16 / 2 )

( 48 / 6 ) ÷ ( 6 / 6) = ( 8 / 1 )

There are 48 lollipops for every 6 candy bars.

There are 24 lollipops for every 3 candy bars.

There are 16 lollipops for every 2 candy bars.

There are 8 lollipops for every 1 candy bar.

The values of A, B, C and D are 55.04ft² ,9184.50ft , 75.36ft and 38.46ft², the A(C-D)+B= 11214.00

Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2.

Circumference of a circle is the perimeter of a circle. It can be calculated as C= πd or 2πr

calculating A, the area of the circle is 3.14×8²= 200.96

the area of the square= l×l= 16×16= 256

area of the shaded part = 256-200.96= 55.04ft²

calculating B, since the maintenance worker moved round 3 times

3C = 3πd= 3.14×975×3 = 9184.50ft

calculating C

circumference of 3 bowls

= 3πd= 3×3.14×8= 75.36ft

calculating D

area= πr²= 3.14×3.5²

= 38.46ft²

therefore A(C-D)+B= 55(75.36-38.46)+9184.50

= 2029.5+9184.5

= 11214.00

The solution of the algebraic equation for the cost of downloading a song for members is x = $0.95

Given that:

1. Peggy pays an annual fee of $10.75. Last year she downloaded 105 songs

2. Non-members pay $0.35 more per song download than members

3. Daniel is not a member of the club and downloaded 85 songs last year

Let x represent the cost of downloading a song for members

Thus, the cost of a song for Peggy will be x

From statement 2: the cost of a song for Daniel will be x+0.35

The algebraic equation for the total amount for Peggy will be:

A = 105x + 10.75

The algebraic equation for the total amount for Daniel will be:

A = 85(x+0.35)

If Daniel and Peggy both paid the same total amount, we can say:

105x + 10.75 = 85(x+0.35)

105x + 10.75 = 85x + 29.75

105x - 85x = 29.75 - 10.75

20x = 19

x = 19/20

x = 0.95

Thus, the cost of a song for member is $0.95

The value of t while considering a right-tailed test (upper tail) and a sample size of 40 at the 95% confidence level is ±1.685.

Given:

Consider a right-tailed test (upper tail) and a sample size of 40 at the 95% confidence level.

we are asked to determine the t value:

The directional hypothesis is:

Hₐ : µ > µ₀

The sample size is, n = 40.

The significance level is:

α = 1-0.95 = 0.05

Use the t-table to compute the right-tailed t-critical value as follows:

tₐ,₍ₙ₋₁₎ = t₀.₀₅,₍₄₀₋₁₎

        = t₀.₀₅,₃₉

        ≈ t₀.₀₅,₄₀

        = 1.684

        ≈ 1.685

The value is positive since the directional hypothesis suggests that the test is right tailed.

The paper's smallest dimensions are height=8.660in and width=17.321in.

In physics and mathematics, the dimension of space is the smallest set of coordinates needed to specify any point within a mathematical space.

A line has a dimension of one because only one coordinate is needed to specify a point on a line, such as a point at 5 on a number.

So, we have:

Area = 150in²

Side margin = 1 in

Top and Bottom Margin = 2 in

To obtain the smallest dimensions, calculate as follows:

The printed material's area is:

Area = l*w

A1 = h*w

A1 should be changed to 150:

150 = h*w

h = 150/w

The complete paper's topic is:

Area = l*w

A2 = (w+2+2)*(H+1+1)

A2 = (w+4)*(H+2)

For H, substitute 150/W:

A2 = (w+4)*(150/w+2)

A2 = w(150/w+2) + 4(150/w+2)

A2 = 150 + 2w + 600w + 8

A2 = 2w = 600/w + 8 + 150

A2 = 2w = 600/w + 158

Calculate a difference with regard to w and set the outcome to 0:

A'2 = 2-600/w²+0

A'2 = 2-600/w²

0 = 2 - 600/w²

2 = 600/w²

2*w² = 600

w² = 600/2

w² = 300

w = 17.321

Remember that:

h = 150/w

h = 150/17.321

h = 8.660

Therefore, the paper's smallest dimensions are height=8.660in and width=17.321in.

Step-by-step explanation:

Abiona should buy the first bicycle ($190) because it is cheaper than the second bicycle ($212.8)

Given that:

The original price of each is $380

The first bicycle is marked down by 50%

The second bicycle is marked down by 30% first and then an additional 20% off

The price of the first bicycle after the discount will be:

price = 380 - (0.5×380)

price = $190

The price of the second bicycle after the discount will be:

After 30% discount:

price = 380 - (0.3×380) = $266

After 20% discount:

price = 266 - (0.2×266) = $212.8

If Shen produced and Manuel consumed one additional bottle of water, total surplus would be $2

The law of supply and demand combines two fundamental economic ideas that describe how changes in the price of a resource, commodity, or product affect its supply and demand.

Supply grows as the price rises, but demand drops. In contrast, as the price falls, supply is constrained and demand is increased.

Demand and supply levels for different prices can be displayed as curves on a graph. The intersection of these curves symbolizes the process of price discovery in the marketplace, as it indicates the balance, or market-clearing price, at which demand equals supply.

According to the law of demand, demand for a good or resource will decrease as its price increases and increase as its price decreases.

How to solve?

Price ------ Quantity Supplied ----- Quantity Demanded

After approximately 113 minutes, there will be only 40 bacteria remaining.

Half-life is defined as the time it will took a substance to reduce to half of its initial amount. The half-life of a substance is determined with respect to the rate of the reaction. It can be calculated using the formula below.

N(t) = N₀(1/2)^(t/T)

where N(t) = amount of substance remaining after time t

N₀ = initial amount of substance

t = time

T = half-life

If the sample begins with 500 bacteria, and after 16 minutes there are 350 bacteria, then

N₀ = 500, and N(t) = 350 when t = 16 minutes

Substitute the given values and solve for the half-life.

N(t) = N₀(1/2)^(t/T)

350 = 500(1/2)^(16/T)

T = 31.09 minutes

Using the formula, solve for t when n(t) = 40.

N(t) = N₀(1/2)^(t/T)

The percentage reduction is 40% if the original number was 5 and the new quantity is 3.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics.

If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

A percentage is a value expressed as a decimal. Divide the percentage value by 100 to convert percentages to decimals and fractions.

The Latin word per centum, which means "hundred" or "by the hundred," is where the word "percent" originates.

The Italian word per cento, which means "for a hundred," gradually shrank to become the symbol for "percent."

Per was frequently shortened to "p" and eventually vanished entirely. The contemporary "%" symbol was created by condensing the "cento" to two circles divided by a horizontal line.

According to our question-

5 were originally ordered, however only 3 were added, resulting in a net drop of 1.

(5 - 3) = 2.

Now, we'll divide net change by the initial amount and multiply it by 100% to get the percentage change, which is,

(2/5)×100%.
