Answer:

9/4 or 2 1/4

Step-by-step explanation:

2 7 /8 -5/8 which gives you 9/4

Answer:

-1 -9i, where a = -1 and b = -9

Step-by-step explanation:

1st step is to open up the brackets. Since there's a (-) in front of the second bracket, we have to multiply every term by -1, so positive becomes negative, negative becomes positive etc.

4-i-5-8i

Then we collect like terms.

-1 -9i

This is the answer. It looks wrong since the variables are 'positive' in a +bi, but you have to remember that a variable can be represented as a, but its actual value could be negative, in this case -1. This is the same with b, as b could be the same as -9.

This is an expression, so we can't multiply everything by -1 to make it 'look right'. You can only multiply by -1 or 'alter' the terms when the expression equates to something.

Answer:

2

Step-by-step explanation:

Since they are similar triangles then the ratio will be the same on all sides.

You know the one side 5 is the same ratio to 5x   so you multiply x to all sides of the little triangle to get the value of the equivalent side in the big one.

so the missing side x times x will equal the big size of the bigger triangle which is 4

x times x = 4   can only be 2

Answer:

6 in long ; 4 in wide

Step-by-step explanation:

With a scale of 1:20

Scaled drawing is 3 in long ; 2 in wide

Actual dimension :

Length = 20 * 3 = 60 in

Width = 20 * 2 = 40 in

Hence, to make a scaled drawing using 1 :10

Dimension :

Length = (1/10) * 60 = 6 inches

Width = (1/10) * 40 = 4 inches

Answer:

x = 3 or x = 7

Step-by-step explanation:

X² - 8x + 14 = 2x - 7

x² - 8x + 14 - 2x + 7 = 0

Now we have a quadratic equation ;

x² - 10x + 21 = 0

-3 and - 7 gives a sum of - 10 and a product of 21

x² - 3x - 7x + 21 = 0

x(x - 3) - 7(x - 3) = 0

(x - 3) = 0 or (x - 7) = 0

x = 3 or x = 7

Answer:

1. yes

2. yes

3. no

4. no

5. yes

Step-by-step explanation:

The questions you're asking relate to the Triangle Inequality Theorem, which states that the two smallest sides (ex. 6 and 13) have to be of greater value than the largest side (ex. 18)

1. 6+13>18

2. 34+27>58

3. 29+9=38 (since the value of the two smallest sides are equal, it does not apply to the Triangle Inequality Theorem, and therefore won't be a triangle)

4. 12+12<25

5. 19+14>31

Answer:

I dont think it that would be the solution because 14 has to be greater and not equal.

Step-by-step explanation:

3(b) + 2 < 14

3(4) + 2 < 14

12 + 2 < 14

14 < 14

Step-by-step explanation:

Since this scuba diver descends below the surface of a lake at a rate of 12 feet per minute, an integer which represents the depth of the diver after four (4) minutes is 48 feet.

The rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.

Mathematically, the rate of change for the depth covered by this scuba can be calculated by using this formula;

Rate of change = Depth/time

Making depth the subject of formula, we have:

Depth = Rate of change × time

Substituting the given parameters into the formula, we have;

Depth = 12 × 4

Depth = 48 feet.

Hope this helps!

The maximum  number of miles Rachel can run on the third day without going over the planned average of  6.4 miles per day is 6.1 miles.

Let x represent the maximum  number of miles

Formulate

6.6+6.5+x÷3=6.4

Hence:

6.6+6.5=6.4×3

13.1+x=19.2

x=19.2-13.1

x=6.1 miles

Inconclusion the maximum  number of miles Rachel can run on the third day without going over the planned average of  6.4 miles per day is 6.1 miles.

Question:

Jin Ya take the bus across town to school each morning last week he timed his trips and found that the time varies day today the time in minutes or listed below:

10 15 11 13 11

If you had to use one number to tell someone how long it took Jin Ya to get to school, what would you say?

Answer:

11 minutes or 12 minutes

Step-by-step explanation:

Given:

10 15 11 13 11

Required

Determine one number that summarizes the 5 numbers

First, one can use the mean to get the summary of the numbers.

The mean is calculated as:

[tex]Mean = \frac{Sum\ of\ observation}{Number\ of\ observation}[/tex]

[tex]Mean = \frac{10 + 15 + 11 + 13 + 11}{5}[/tex]

[tex]Mean = \frac{60}{5}[/tex]

[tex]Mean = 12[/tex]

Another number that summarizes the numbers is the mode of the distribution.

[tex]Mode = Highest\ Occurring\ Value[/tex]

So, in this case:

[tex]Mode = 11[/tex]

Hence, you can either use 11 minutes or 12 minutes.
