4 gallons of low fat milk cost 1.80, Find the cost of 6 gallons of low fat milk.

Answers

Answer:

2.70

Step-by-step explanation:

4 gallons 1.80

2 gallons 0.90(half)

6 gallons 2.70(both above)

Answer:

$2.70

Step-by-step explanation:

Divide 1.80 by 4 = $45 Cents

( Check : 45 x 5 = 1.8) (* Add 0 )

So since it is now known that a gallon of low fat milks costs $45 cents per gallon, multiply 6 by 0.45 and you'll get 2.7

So it can be a type of currency,

add 0

So the reuslt would be $2.70

Therefore, the cost of 6 gallons of low fat milk is $2.70 ( 2 dollars and 70 cents).

Vladimir is looking to retire in 10 years. He has a plan to put $25,000 into an investment today that earns interest at a fixed amount per year. What would be a reasonable domain and range for a function modeling the total amount of the investment, including interest?
25 Points for the correct answer

Answers

The domain and range for a function modeling the total amount of the investment, including interest are as follows;

Domain, X = {0<= years <= 10}Range, Y (total amount) = {$25,000<= Y <= 25,000( 1 + 10R)}

The starting principal amount, P is $25,000.

Let the interest rate per year, be represented as, R (%)

Time of investment, T = 10 years

In essence, after 10 years, the total amount Vladimir has is;

Total amount = 25,000( 1 + xR).

In essence, the domain (No. of years ) is;

Domain, X = {0<= years <= 10}

Range, Y (total amount) = {$25,000<= Y <= 25,000( 1 + xR)}

Answers

Answer:

3/20x−3

Step-by-step explanation: TOOK THE FOR K12 HOPE THIS HELPS

The difference of the given expression is 3/20 x - 3.

Given that, (2/5x−1)−(1/4x+2).

What is the subtraction of expressions?

To subtract an algebraic expression from another, we should change the signs (from '+' to '-' or from '-' to '+') of all the terms of the expression which is to be subtracted and then the two expressions are added.

Now, (2/5x−1)−(1/4x+2)

= (2/5 x - 1/4 x) -1 - 2

= (8/20 x - 5/20 x) - 3

= 3/20 x - 3

Therefore, the difference of the given expression is 3/20 x - 3.

78.95 in standard form

Answers

Answer:

[tex]7.895[/tex] × [tex]10^1[/tex]

Step-by-step explanation:

Standard form is a way of writing a number so it is easier to read. It is often used for very large or very small numbers. Standard form is like scientific notation and is typically used in science and engineering.

--A number is written in standard form when it is represented as a decimal number times a power of 10.

As an example, consider the speed of light which travels at about 671,000,000 miles per hour. Written in standard form this number is equivalent to 6.71 x 10^8.

Show all work to identify the asymptotes and zero of the function f of x equals 4 x over quantity x squared minus 16.

Answers

9514 1404 393

Answer:

asymptotes: x = ±4, y = 0zero: x = 0

Step-by-step explanation:

The function factors as ...

[tex]f(x)=\dfrac{4x}{(x-4)(x+4)}[/tex]

The vertical asymptotes are found where the denominator factors are zero:

x-4 = 0 ⇒ x = 4

x+4 = 0 ⇒ x = -4

The zero of the function is where the numerator is zero:

4x = 0 ⇒ x = 0

The horizontal asymptote of the function is the value of 4x/x² when x tends to infinity. That value is zero. The equation of the horizontal asymptote is ...

Each sheep has 4 legs and each chicken has 2 legs.if a farm boy counts 50 heads and 130 feet, how many sheep are there

Answers

Answer:

15 sheep

Step-by-step explanation:

1 leg = 1 foot

1 head = 1 animal

Suppose all the animals are chickens:

50 × 2 = 100

130 - 100 = 30

4 - 2 = 2

30 ÷ 2 = 15

Hence, there are 15 sheep.

Blank two the options are: one-seventh, one-twelfth, three twenty-sixths, or thirty-six thirds

Blank three the options are one, eighty-four, seven twelfths, or twenty-one twenty-sixths

Please help me with the problem.

Answers

List all the info:

3/8 gallon of white paint

2 7/8 gallon of blue paint

11/4 gallon of red paint

First, let’s answer the first question.

Francis has made _____ gal of paint when he first mixes the three colors.

Add all the gallons of paints together and you get 6. So, Francis has made 6 gal of paint when he first mixes the three colors.

Now for the second blank. All you have to do is do 6 divided by 3/8 which is 16. So, The constant of proportionality of white paint to gallons of mixed paint is 16.

Lastly, you will have to do is 3/8 x 7 = 2 5/8. (Im not too sure about this part though, but the rest I‘m pretty confident about)

Quinn leaves her house at 10:00 am and runs 3 miles at a steady pace of 6 miles per
hour. She relaxes and takes a lunch break for 1 hour. She is pretty tired so she walks
home at a steady pace of 2 miles per hour. What time does Quinn return home

Answers

Using the relation between velocity, distance and time, it is found that Quinn returns home at 1 pm.

Velocity is distance divided by time, that is:

[tex]v = \frac{d}{t}[/tex]

She walked 3 miles at a velocity of 6 miles per hour, thus [tex]d = 3, v = 6[/tex]. The time is:

[tex]v = \frac{d}{t}[/tex]

[tex]t = \frac{d}{v} = \frac{3}{6} = 0.5[/tex]

Thus, she arrived at 10:30 am, and took a lunch break of 1 hour, so she started to return at 11:30 am.Distance of 3 miles, velocity of 2 miles per hour, thus [tex]d = 3, v = 2[/tex]. The time she took to return, in hours, is:

[tex]t = \frac{d}{v} = \frac{3}{2} = 1.5[/tex]

1.5 hours after 11:30 am is 1 pm, thus, Quinn returns home at 1 pm.

The width of a rectangular field is 20 centimeters. The perimeter is at least 648 centimeters. Write and solve an inequality to find the possible lengths of the field.

Answers

The possible length of the rectangular field as represented by an inequality is; l ⩾ 322 centimetres

The perimeter of a rectangular field is;.

Perimeter = (2 × length) + (2 × width)

However; the perimeter of the field is at least 684 centimetres.

Therefore;

[tex]perimeter \geqslant 684cm[/tex]

Therefore;

2l + 2w ⩾ 684

2l + (2 × 20) ⩾ 684

2l + 40 ⩾ 684

2l ⩾ 644

l ⩾ 644/2
