Answer:

3a) 5/45 you divide by 5

3b) 6/7 you divide by 2

3c) 2/7 you divide by 9

3d) 2/5 you divide by 9

4a) 6

4b) 1 1/4 or 5/4 (both are correct)

4c) 3 1/2 or 3 3/6 (both are correct)

4d) 5 1/8

The fraction bar tells you to divide the top number by the bottom number.

Step-by-step explanation:

For 3a through 3d, you just use the fraction that has a missing number, and if the missing number is at the bottom, use the top number and devide it by the other top number that the fraection is equal to.

For 4a through 4b, devide the top the bottom number

Answer:

A) c = 5 ft

Step-by-step explanation:

a = 3

b = 4

3^2+4^2 = c^2

c^2 = 9+26 = 25

c = 5

Answer:

B

Step-by-step explanation:

Unfortunately, I dont really have a explanation for this besides yellow square is larger than both red and green, so using judging by the answers, it has to be B.

Answer:

Step-by-step explanation:

you mean (-4+2i)-(5-4i)

=-4+2i-5+4i

=-9+6i

Based on the equation, to eliminate the x terms and solve for y in the fewest steps; the first equation should be multiplied by 3 and the second equation by 5.

6x - 5y = 17

7x + 3y = 11

Using elimination method

18x - 15y = 51

35x + 15y = 55

18x + 35x = 51 + 55

53x = 106

x = 106/53

x = 2

6x - 5y = 17

6(2) - 5y = 17

12 - 5y = 17

-5y = 17 - 12

-5y = 5

y = 5/-5

y = -1

Therefore, the solution to the simultaneous equation; 6x - 5y = 17, 7x + 3y = 11 is x = 2 and y = -1

Answer:

Answer:

commutative property of multiplication

Step-by-step explanation:

Answer:For these, n is equal to the term you want. So you substitute the number in for whichever term you want. This means:

a) 1 (1st term) + 5 = 6

2 (2nd term) + 5 = 7

3 (3rd term) + 5 = 8

4 (4th term) + 5 = 9

10 (10th term) + 5 = 15

And so on for b (not going to keep writing the term, I’m sure you get that by now.

b) 2(1) - 1 = (2x1) - 1 = 1

2(2) - 1 = (2x2) - 1 = 3

2(3) - 1 = (2x3) - 1 = 5

2(4) - 1 = (2x4) - 1 = 7

2(10) - 1 = (2x10) - 1 = 19

Answer: Yes, your friend is correct

Additional Note: Associative Property is modifying the addendum grouping does not alter the number.

Answer: The friend is wrong.

Step-by-step explanation:

In this equation, they are doing the commutative property. Commutative property is a property that the numbers on which we operate can be moved or swapped from their position without making any difference to the answer. The Associative Property of Addition is a property which means that rearranging the parentheses in an expression will not change the result. Clearly, they didn’t do that; they just switched the 7 and x around which is the commutative property.

This might be slightly confusing but I hope this helps :’)

Answer:

P(X = 0) = 0.12.

P(X = 1) = 0.37.

P(X = 2) = 0.43.

P(X = 3) = 0.08

Step-by-step explanation:

12% have no children

This means that P(X = 0) = 0.12.

37% have one child

This means that P(X = 1) = 0.37.

43% have two children

This means that P(X = 2) = 0.43.

8% have three children.

This means that P(X = 3) = 0.08

Answer:

The relation is [tex]y = -1.5x[/tex]

Step-by-step explanation:

x and y are directly proportional:

This means that the equation is given by:

[tex]y = ax[/tex]

In which a is the multiplier that relates these two variables.

x= -4, y =6

We use this to find a. So

[tex]y = ax[/tex]

[tex]6 = -4a[/tex]

[tex]a = -frac{6}{4}[/tex]

[tex]a = -1.5[/tex]

So

The relation is [tex]y = -1.5x[/tex]

The larger number is 301804

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Given;

The smaller number =6 524,

The difference between two numbers = 308 328

Now,

Let the missing number be x

x-6524=308328

x=308328-6524

x=301804

Therefore, the larger number of algebra will be 301804.

#SPJ2

Answer: See explanation

Step-by-step explanation:

ΔLNM and ΔLKN are 30°- 60°- 90° triangles

We have to find the length of LN before we can find the length of MN.

In a 30°- 60°- 90° triangle, the length of the hypotenuse is 2 times the length of the shorter leg, and the length of the longer leg is the length of the shorter leg times √3

Since the hypotenuse is 6, the short leg would be 3 since the hypotenuse is 2 times the length of the short leg.

LN = √3 times the shorter leg

3 × √3 = 3√3

LN = 3√3

We now know the length of the longer leg in ΔLNM (3√3)

MN would be 3√3 × √3

3√3 × √3

= 3√9

= 3 × 3 = 9

MN = 9

ΔLKM is also a 30° - 60° - 90° triangle

The short leg is 6 m

The hypotenuse would be 12 m

The longer leg would be 6√3

Perimeter: 6 + 12 + 6√3

The perimeter is 18 + 6√3

Area: 1/2 × b × h

b = 6√3

h = LN = 3√3

6√3 × 3√3

18√9 = 18 × 3 = 54

Area: 54 m²

Answer:

The value of the parameter of interest in this setting is:

d. The value of the parameter of interest cannot be determined from the given information.

Step-by-step explanation:

To determine the parameter of interest in this setting, we need information about the population figure of the small-to-medium-sized streams in eastern North Carolina.  We also require the population proportion of these streams, which have runoff from hog farms.  But in this situation, the information is lacking.  Instead, we are given information about the sample, which only produces statistics.  For example, we can calculate the average (mean) proportion of the sample of 242 small-to-medium-sized streams using the 55 that were found to have runoff from hog farms.

Answer:  B.  (5,11)

Step-by-step explanation:

c  = 6 + 1s          In this case we know that c is your total cost and s is the number of downloaded songs.

If we were to do it in terms of x and y, y will be c, and x will be s.

Now is asking for the cost of 5 songs, so you will input the value 5 into the equation for s and solve for c.

c = 6 + 1(5)

c = 6 + 5

c = 11

Now we know that for 5 songs it will cost you $11, and if x is the same as the number of songs, and y is the total cost then we can say that the point will be,

Answer:

7.5

Step-by-step explanation:

The ratio between the two numbers in each set are the same, so the process used to get from 4 to 6 could also be used to find x. 6/4=1.5, so 4*1.5=6. Multiplying 5 by 1.5 would get x. 5*1.5=7.5, so x=7.5.
