Answer:

see below

Step-by-step explanation:

sqrt( -6) * sqrt(-24)

We know that sqrt(a b) = sqrt(a) sqrt(b)

sqrt(6) sqrt(-1)  * sqrt(24) sqrt(-1)

We know that sqrt(-1) = i

sqrt(6) i  * sqrt(24) i

We know that sqrt(a) sqrt(b) = sqrt(ab)

sqrt(6*24) i*i

sqrt(144) i^2

12 i^2

We know that i^2 = -1

12 (-1)

-12

Answer:

[0, infinity)

Step-by-step explanation:

The domain is including all numbers from 0 to infinity.

The reason negative numbers are not included is because of the [tex]\sqrt{x}[/tex]. A negative number cannot be included there, otherwise it would be what's called an "imaginary number" (i).

Therefore, every number besides negative numbers are included in the domain.

Answer:

£3.50

Step-by-step explanation:

£4.90 = 7/8

£4.90/(7/8) = £5.60 (Total Amount of Money)

£5.60 x (5/8) = £3.50

Answer:

£3.50

Step-by-step explanation:

    [tex]\frac{7}{8}[/tex] = £4.90

(÷7)              (÷7)

    [tex]\frac{1}{8}[/tex] = £0.70

(×5)              (×5)

Step-by-step explanation:

Answer:

15/20 and 18/20

Step-by-step explanation:

Least common denomintor of 3/4 and 9/10 = least common multiple of 4 and 10

multiples of 4: 4, 8, 12, 16, 20

multiples of 10: 10, 20

Least common denominator = 20

Rewrite fractions: 15/20 and 18/20

3/4 and 9/10 using the least common denominator is 15/20 and 18/20.

LCM of two or more than two given numbers is the smallest common multiple that is divisible by two or more than two given numbers.

Given, are two fractions 3/4 and 9/10 we know the LCM of 4 and 10 is 20.

∴ (3×5)/(4×5) and (9×2)/(10×2).     (we have to multiply same constant to the  

                                                         fraction to retain it's original value).

So,  3/4 and 9/10 using the least common denominator is 15/20 and 18/20.

Answer:

b

Step-by-step explanation:

The correct answer for the given problem above would be option B.

⇒ Fran must work 17 hours per week to meet her goal.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Now, According to the given details,

Fran works 15 hours per week for $225 which makes it $15 per hour.

Hence, If she adds another 2 hours per week to make it 17 hours,

Then, she will earn $255 dollars per week.

Now, since she is saving $40 dollars plus the two hours which is $30, a total of $70 per week of savings, multiplied by 20 weeks, then, she will be able to get $1,400.

Hence, The correct answer for the given problem above would be option B.

⇒ Fran must work 17 hours per week to meet her goal.

Answer:

6.66 hours, that is, 6 hours and 40 minutes.

Step-by-step explanation:

If Mike can plow a field in 12 hours, we plows 1/12 of the field each hour.

If Phil can plow a field in 15 hours, we plows 1/15 of the field each hour.

So if they are working together, they can plow (1/12) + (1/15) of the field each hour, that is:

(1/12) + (1/15) = (5 + 4) / 60 = 9 / 60 = 3 / 20 = 1 / 6.66

So if they work together, they can plow the field in 6.66 hours, that is, 6 hours and 40 minutes.

Scale factor = 4/12 = 1/3

Answer: 77 percent

Step-by-step explanation:

The value of the stock decrease by 23.13%.

The difference between starting and final numbers is the percentage drop. It displays a percentage loss of value compared to the original regardless of the units. The difference between the initial and final amounts is the amount of decline.

Given:

The price of the stock was $35.48.

Then The price of the stock is $27.36.

So, the decrease in amount= 35.48 - 27.36 = 8.12

Then, percent decrease

= 8.12/ 35.48 x 100

= 23.13%

Hence, the percent decrease is 23.13%.
