What is greater 2/5 or 3/4

What is 1 6/7 -1 4/11

Answers

Convert both numbers to improper fractions, and to do that, multiply the denominator and whole number, and add the numerator.

If done correctly, you should get 13/7 - 15/11.

Now, we have to find the LCM of both denominators.
77 is the LCM.

77 is the LCM.

You needed to multiply 7 by 11 to get 77, so multiply 13 by 11, too.
13 x 11 = 143
We get 143/77.

Do the same with the other fraction.
You needed to multiply 11 by 7 to get 77. So multiply 15 by 7.
15 x 7 = 105
We get 105/77

Now you can subtract.

143/77 - 105/77 = 38/77
LCD = 77
1 66/77 - 1 28/77= 38/77

(2 5/8 + 2 1/2) - 4 2/3

Answers

Steps:
1. Do 2 5/8 + 2 1/2 by changing them so they have the same denominators. Since 2 goes into 8, 8 would be your common denominator.
2. Multiply 2 times 4 which equals 8. Multiply 1 times 4 which equals 4
3. Your new problem is 2 5/8 + 2 4/8
4. This equals 4 9/8 which equals 5 1/8
5. Do 5 1/8- 4 2/3 by multiplying both denominators and numerators by 3 and the second mixed number by 8
6. 8 times 3 equals 24
1 times 3 equals 3
7. 5 3/24
8. 3 times 8 equals 24
9. 2 times 8 equals 16
10. 5 3/24 - 4 16/24
11. Take from the whole number in 5 3/24
12. 4 27/ 24 - 4 16/24
13. Your answer is 11/24
You need to change the fractions so that they all have a common denominator (the bottom half of the fraction). So you have to fond a number that all three denominators go into. You have 8, 2, and 3. They all go into 24. Times all the fractions by whatever they need to make the bottom 24. but you can only times them by 1, or else it will ruin your equation. [3/3 x 5/8 = 15/24] [12/12 x 1/2 = 12/24] [8/8 x 2/3 = 16/24] now plug your new fractions into the problem. (2 15/24 +2 12/24) - 4 16/24. simplify the part in the parenthesis first, (4 27/24) - 4 16/24. since you are subtracting, you can leave the part in parenthesis as a wrong fraction. now subtract. 4 27/24 - 4 16/24 = 11/24. you can't simplify that to be a smaller number, so that is your answer:)[11/24]

Z=sqrt 2[cos(-pi/4)+isin(-pi/4)]=a+bi what is a and b?

Answers

Answer:

\boxed{\boxed{a=1,b=-1}}

Step-by-step explanation:

The given expression is,

z=√(2)\left[\cos(-(\pi)/(4))+i\sin (-(\pi)/(4))\right]

According to Distributive property,

=√(2)\cos(-(\pi)/(4))+i√(2)\sin (-(\pi)/(4))

we know that,

\cos(-(\pi)/(4))=\cos((\pi)/(4))=(1)/(\sqrt2)

and

\sin(-(\pi)/(4))=-\sin((\pi)/(4))=-(1)/(\sqrt2)

Putting these,

=√(2)\cdot (1)/(\sqrt2)-i√(2)\cdot (1)/(\sqrt2)

=1-i\cdot 1

=1-i

Comparing this to a+bi, we get

a=1,b=-1

Answer: a=1, b=-1

Carla made a scale drawing of a classroom. The length of the classroom in the drawing is 5in. The actual length is 40ft. What scale did Carla use for her drawing?

Answers

Answer:

1/96

Step-by-step explanation:

scale is

a model cannot be as same size as that of actual object ,

hence objects are scales down to some value so that its model can be comfortably made.

scale is generally ratio of length  of drawing and actual length of object

scale = length  of drawing / actual length of object.

Given

length of classroom drawing = 5in

actual length of classroom = 40 ft

as unit of drawing and actual classroom is different lets make unit of class smilar to that of drawing that is in inches

we know

1 feet = 12 inches

thus 40 feet = 12*40 inches = 480 inches

thus,

actual length of classroom in inches = 480 inches

scale used by Carla = length  of drawing / actual length of classroom

                                = 5 inches/480 inches = 1/96 (answer)
