saves $7 each week. At what week will they have the same amount of money?

Answer:

A 4

Step-by-step explanation:

-1/-4 = 4

Answer:

not a real number

Step-by-step explanation:

any negative number under a square root sign, except for 0, isn't real

On evaluating the given roots,

(a) [tex]$-(\sqrt[3]{8}) = -2$[/tex]

(b) [tex]$\sqrt[4]{-81}$[/tex] is not a real number

(a) [tex]$-(\sqrt[3]{8})$[/tex]:

The cube root of 8 is the number that, when raised to the power of 3, equals 8. In this case, the cube root of 8 is 2, because [tex]2^3 = 8[/tex].

Since we have a negative sign in front of the cube root, the result will be the negative value of the cube root of 8.

Therefore, [tex]$-(\sqrt[3]{8}) = -2$[/tex].

(b) [tex]$\sqrt[4]{-81}$[/tex]:

The fourth root of a number is the number that, when raised to the power of 4, equals the given number.

In this case, we are looking for the fourth root of -81.

However, the fourth root of a negative number is not a real number. This is because raising a positive number to an even power (in this case, 4) will always result in a positive value, and there is no real number that, when raised to the power of 4, gives a negative result.

Therefore, the fourth root of -81 is not a real number.

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]

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

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

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

Answer:

y = -4

Step-by-step explanation:

-8y+6(y+5) = 38

-8y + 6y + 30 = 38

-2y + 30 = 38

-2y = 8

8 / -2 = -4

y = -4

Answer:

V= -4

Step-by-step explanation:

-8v+6(v+5) = 38

-8v+6v+30 = 38

-2v = 38-30

-2v = 8

v = 8/-2

v = -4

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).

15 sheep

Step-by-step explanation:

1 leg = 1 foot

1 head = 1 animal

Suppose all the animals are chickens:

4 - 2 = 2

30 ÷ 2 = 15

Hence, there are 15 sheep.

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)

Answer:

[tex]b = 6[/tex]

Answer:

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 ...
