find the value of expression when y=4 6y-78

Answer:

24

Step-by-step explanation:

Think of .5 as 2 and instead of dividing, you're multiplying.

So instead of 12/.5, it would be 12x2, which is 24.

He will pay $24.055 after discount and sales tax.

A sales tax is a fee that is paid to the government when specified goods and services are sold. Typically, laws permit the vendor to charge the customer the tax at the time of purchase. Use taxes are typically used to describe taxes on goods and services that consumers pay directly to a governing authority.

Given Data

Car cost = $24.211

Discount = 8%

Car cost after discount:

= 24.211 - 8%

= 22.274

Car cost after sales tax:

= 22.274(8%)

= 22.274 (0.08)

= 1.781

Cost of car =  22.274 + 1.781

Cost of car = 24.055

He will pay $24.055 after discount and sales tax.

A certain plant grows 1 1/6 inches each week. it will rake the plant to grow 6 1/6 inches is 5 weeks 2 days.

Time is ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future. It is a quantity that is part of several measurements that are used to compare the length of events or the gaps between them, to compare how long they last, to order events, and to measure how quickly the things change in the real world or in our conscious experience. Along with the three spatial dimensions, time is frequently referred to as a fourth dimension.

Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without the circularity has consistently eluded scholars. Nevertheless, diverse fields such as the business, industry, sports, sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.

A certain plant grows every week = [tex]1\frac{1}{6}[/tex] = [tex]\frac{7}{6}[/tex] inches

1 week = 7 days

Therefore in 1 day plant grows = [tex]\frac{\frac{7}{6} }{7}[/tex]

                                                        = [tex]\frac{1}{6}[/tex] inch

Now we have to calculate the number of days in which the plant grows [tex]6\frac{1}{6}[/tex]  inches ≈ [tex]\frac{37}{6}[/tex] inch

Number of days = [tex]\frac{Total growth}{growth in one day}[/tex]

                          = [tex]\frac{37}{6}[/tex] ÷ [tex]\frac{1}{6}[/tex]

                          = [tex]\frac{37}{6}[/tex]  × 6

                          = 37 days ≈ 5 weeks and 2 days

It will take plant 5 weeks 2 days to grow [tex]6\frac{1}{6}[/tex] inches.

The measures of the unknown angles are as follows:

The measures of each angles can be found as follows:

Therefore,

∠AEB = ∠CED (vertically opposite angle)

∠DEA = ∠BEC (vertically opposite angle)

Vertically opposite angles are equal.

Therefore,

4x = 75 - x

4x + x = 75

5x = 75

x = 75 / 5

x = 15

Therefore,

∠DEA = ∠BEC = 4(15) = 60°

∠AEB = ∠CED  = 360 - 120 / 2 = 240 / 2 = 120°

The probability that the amount dispensed per box will have to be increased is 0.0062.

Consider the provided information.

Sample of 16 boxes is selected at random.

If the mean for 1 hour is 1 pound and the standard deviation is 0.1

1 Pound = 16 ounces , then 0.1 Pound = 16/10 = 1.6 ounces

Thus: μ = 16 ounces and σ = 1.6 ounces.

Compute the test probability

z= x−μ/σ/[tex]\sqrt{n}[/tex]

z= 15-16/ 1.6/[tex]\sqrt{4}[/tex]

z= -1/ 0.4

z= -2.5

By using the table.

Probability p value = P(Z<-2.50) = 0.0062

Thus, the probability that the amount dispensed per box will have to be increased is 0.0062.

I guess you want to draw the graph.

The graph is a straight line

-6x - 20 = 4y

When x = 0:

-6(0) - 20 = 4y

y = -20/4 = -5

So, one point on the graph

= (0, -5)

When y = -2:

Plugging y = -2 into the equation:

-6x - 20 = 4(-2)

-6x = -8 + 20 = -12

x = -2

So, another point is (-2, -2)

Mark these 2 points on the graph paper

and draw a line passing through them.

In the question ,

a fraction 3/12 is given ,

we have to find the value of 3/12 of 100 .

to find the value , we first convert both the numbers into fraction

So 100 in fraction form can be written as 100/1

So the value 3/12 of 100 means

= [tex]\frac{3}{12} *\frac{100}{1}[/tex]

multiplying the numerator with numerator

and multiplying denominator with denominator .

we get = 300/12

√134 is the number which is located between 11 and 12 on a number line.

A number line is a horizontal straight line on which real numbers are arranged in equal intervals. This line extends both sides at infinity.

Comparison and operations of numbers can be better explained using number lines.

Taking consecutive perfect squares of integers which lies above and below the given numbers on the number line and taking it's square root, we can find the answer.

The perfect squares below and above 150 are 144 = 12² and 169 = 13². So √150 lies in between 12 and 13.

The perfect squares below and above 134 are 121 = 11² and 144 = 12². So √134 lies in between 11 and 12.

The perfect squares below and above 115 are 100 = 10² and 121 = 11². So √115 lies in between 10 and 11.

The number 121 is itself a perfect square. √121 = 11.

Hence √134 is the number which lies in between 11 and 12.
