Answer:

1h 20m

Step-by-step explanation:

Let the total amount of work be x.

Shannon:

2h = x

1h = [tex]\frac{1}{2}[/tex]x

So basically Shannon does  [tex]\frac{1}{2}[/tex]x work per hour.

Sarah:

4h = x

1h = [tex]\frac{1}{4}[/tex]x

So basically Sarah does [tex]\frac{1}{4}[/tex]x work per hour.

Together:

1h = [tex]\frac{1}{2}[/tex]x + [tex]\frac{1}{4}[/tex]x

    = [tex]\frac{2}{4}[/tex]x + [tex]\frac{1}{4}[/tex]x

    = [tex]\frac{3}{4}[/tex]x

Amount of time spent = [tex]\frac{4}{4}[/tex]x ÷ [tex]\frac{3}{4}[/tex]x

                                     = [tex]\frac{4}{4}[/tex]x × [tex]\frac{4}{3}[/tex]x

                                     = [tex]\frac{16}{12}[/tex]h

                                     = 1[tex]\frac{4}{12}[/tex]h

                                     = 1h 20m

Answer:

4/3 hours

Step-by-step explanation:

For every hour that Sarah mows, Shannon mows twice as much. Because of this, Sarah is going to mow two times as much of the field as Shannon. You can set up an equation where x is the fraction of lawn mowed. This equation should be:

2x + x = 1 -> 3x = 1

The reason the equation is set up like this is because there is 1 whole lawn that the fraction of the lawn that Shannon mows (2x) plus the fraction of the lawn that Sarah mows (x) adds up to. You can use this equation to solve for x, which will be 1/3.

Since you know x, you can find what fraction of the lawn Shannon and Sarah mow. Since Shannon mows a fraction of 2x of the lawn, the fraction she mows will be 2*1/3 = 2/3. The fraction that Sarah mows will be x = 1/3.

Now that you know the fraction of the whole lawn that both Saran and Shannon mow, you can multiply their respective fraction by the amount of time it takes for them to mow a whole lawn. To do this for Shannon, you multiply 2/3 of the lawn by 2 hours, which gives you 4/3 hours. To do this for Sarah, you multiply 1/3 of the lawn by 4 hours, which also gives you 4/3 hours.

The nth term of an arithmetic progression is expressed according to the equation;

Tn = a + (n-1)d

where

a is the first term

n is the number of terms

d is the common difference

Determine the common difference

d = 42-b = b - 30

-b-b = -30-42

-2b = -72

b = 36

d = 36-30

d = 6

For the first term;

d = 30 - a

6 = 30 - a

a = 24

For the value of c

c = 42 + 6

c = 48

For the value of d

d = 48 + 6

d = 54

For the value of e

e = 54 + 6

e = 60

Hence the complete sequence is 24, 30, 36, 42, 48, 54, 60

The base of the given expression will be 4.

Here, we are given that 4 is multiplied by itself 7 times, that is-

4 x 4 x 4 x 4 x 4 x 4 x 4

As anything raised to the power 1 is the number itself, the given expression can also be written as follows-

[tex]4^{1} * 4^{1} *4^{1} *4^{1} * 4^{1} *4^{1} *4^{1}[/tex]

Now, we know that when we need to find the product of 2 numbers whose bases are same, we can simply add the powers. Mathematically this can be represented as follows-

[tex]a^{n}a^{m} =a^{n+m}[/tex]

Thus, the given expression will become-

[tex]4^{1} * 4^{1} *4^{1} *4^{1} * 4^{1} *4^{1} *4^{1}[/tex] = [tex]4^{1+1+1+1+1+1+1}[/tex]

= [tex]4^{7}[/tex]

Thus, we see that when 4 is multiplied 7 times, the base comes out to be 4 only.

Step-by-step explanation:

Each recipe of waffles requires 3/4 cups of butter

Mrs Claus has 4 1/2 cups of butter

Therefore the number of recipes which she will be able to make can be calculated as follows

= 4 1/2 ÷ 3/4

= 9/2 ÷ 3/4

= 9/2 × 4/3

= 6

Hence Mrs Claus can make 6 recipes

Answer:

A

Step-by-step explanation:

Okay.

A negative exponent means we want to "flip" the term.

so we get

(1/-c^2)^1/3

When we get a fraction exponent, we want to "root" the term by that

so we get

[tex]\sqrt[3]{\frac{1}{-c^2} }[/tex]

Which simplifies to

[tex]\frac{\sqrt[3]{1} }{\sqrt[3]{-c^2} }[/tex]

Which becomes[tex]1/\sqrt[3]{-c^2}[/tex]

Therefore, the slope of a line on a standard XY-plane that passes through points (1, 3) and (4,-3) is -2.

So, option (c) is correct.

Given two points are (1, 3) and (4, -3)

We need to find the slope of a line

The slope of a line (m) :

m = y₂ - y₁ / x₂ - x₁

Given (x₁, y₁) =  (1, 3) and (x₂, y₂) =  (4, -3)

Slope (m) =  y₂ - y₁ / x₂ - x₁

                = -3 - 3 / 4 - 1

                = -6 / 3

                = -2

Therefore, the slope of a line on a standard XY-plane that passes through points (1, 3) and (4,-3) is -2.

So, option (c) is correct.
