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:

Because the x line is for degrees C and the y is for Degrees F and the y intercept is where C is at 0 and F is at 32 making it the temp in F when C is at 0 degrees

Answer:

k=29

Step-by-step explanation:

(5K-3)+(9+k)=180

6k+6=180  add like numbers

6x=174        subtract 6 from 180

x=29           divide by 6

The solution is : k=29, is the value of k.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

Here, we have,

from the given diagram, we get,

(5K-3)+(9+k)=180

6k+6=180     [add like numbers]

6x=174       [ subtract 6 from 180]

x=29          [ divide by 6]

Hence, The solution is : k=29, is the value of k.

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.

Answer:

The slope decreases and the y-intercept decreases.

Explanation:

Red is original, blue is when y is doubled.

Answer:

a) y=(300-150)x-2100

b) y=150x-2100

c) y=150(140)-2100

y=18900

Jose was wrong. He did not make 20000 dollars last year.

Answer:

A: ((300-150) * 140) - 2100

B: 21000-2100= $18,900 profit.

Jose made 18,900 dollars worth of profit. He did not make $20,000 worth of profit.

Answer:

First mistake appears in First Step

Step-by-step explanation:

First mistake appears in First Step, within the parenthesis need to solve division first.

2 + 5 x (4 + 18 ÷ 6)

Step 1 should be 18 ÷ 6

2 + 5 x ( 4 + 3 )

Step 2 is 4 + 3

Step 3 is 5 x 7

2 + 35

Step 4 is 2 + 35

Steps:

Step 1: Simplify both sides of the equation.

4x+3=9

Step 2: Subtract 3 from both sides.

4x+3−3=9−3

4x=6

Answer:

19b-4

Step-by-step explanation:

7b+3(4b-2)+6÷3

Bracket comes first so we distribute 3 over the terms in the bracket

= 7b + 12b -6 +6 ÷ 3

First we solve division

= 7b + 12b -6 +6 ÷ 3

= 7b + 12b -6 +2

= (7b+12b)+(-6+2)

= 19b -4

This can't be simplified further as it can't be solved anymore

Answer:

19b - 4

Step-by-step explanation:

Distribute the 3 to (4b - 2), like so:

3(4b - 2)

12b - 6

→ 7b + 12b - 6 +6 ÷ 3

Add like terms:

→19b - 6 + 6 ÷ 3

Following PEMDAS, you divide 6 by 3 first:

→19b - 6 + 2

Add like terms:

→19b - 4

The United States federal earned income tax credit or earned income credit is a refundable tax credit for low- to moderate-income working individuals and couples, particularly those with children.

Answer:

x = 18

Step-by-step explanation:

Given

[tex]\frac{3x}{5}[/tex] + 1 = [tex]\frac{4x}{15}[/tex] + 7 ( subtract 1 from both sides )

[tex]\frac{3x}{5}[/tex] = [tex]\frac{4x}{15}[/tex] + 6

Multiply through by 15 to clear the fractions

9x = 4x + 90 ( subtract 4x from both sides )

5x = 90 ( divide both sides by 5 )

x = 18

Answer:

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:

Given below

Step-by-step explanation:

M is Mikey and B is Betty in,

Current ages:

M= x

B= 3x (cuz she is 3 times older)

After 5 years

M= x+5

B= 3x+5 (5 years added to present age)

It says the ages of Betty after 5 years (3x+5) will be twice as much as Mikey (2(X+5))

So,

3x+5 = 2(x+5)

3x+5 = 2x+10

3x -2x = 10-5

x = 5

Therefore,

The current ages are

Betty : 3x = 3*5 = 15

Mikey: 5 (x)

Answer: 36

The LCM of 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11 is 2 × 3 × 2 × 5 × 7 × 2 × 3 × 11 = 27720.

A multiple of 27720 will end in 0, and the sum of its digits will be a multiple of 9.

The largest 6-digit number which is multiple of 9 with last digit of 0 is 999990, and the sum of its digits is 45. 45 is not a multiple of 27720, and there is no other way to get a digit sum of 45.

We now look at the next biggest multiple of 9, 9 × 4

= 36.

The largest 6-digit multiple of 27720 is 27720 × 36 = 997920, and the sum of its digits is 36.

Answer: It means that there are 570 chocolate chips in all the 30 cookies

Step-by-step explanation:

The mean also referred to as the average of a data set is calculated by adding all numbers in a data set and dividing by number of values in the set.

Since the mean number of chocolate chips in 30 cookies is 19 chocolate chips, this means that there are:

= (30 × 19) = 570 chocolate chips in the cookies.
