what is 5.128 + 2.624 (show ur work)

Answer:

5

Step-by-step explanation:

5 x 2 is 10 and 48 plus 10 is 58

Answer:

4th one

Step-by-step explanation:

because its a line (linear)

Answer:

1. Ursula = y

2. Alma = y - 3 (3 meters behind)

3. Carly = y - 6 (3 meters behind Alma)

4. Lani = y - 8 (2 meters behind Carly)

5. Isabel = y - 10 (2 meters behind Lani)

6. Betty = y - 12 (2 meters behind Isabel)

Step-by-step explanation:

We are going to use different letters to represent the meters run by the girls:

Alma beat isabel by 7 meters, if A is x then Isabel is x - 7

A = x

I = x -7

Ursula beat  Betty be 12 meters. Let's call Ursula y, then:

U  = y

B = y - 12

Alma finished 5 meters ahead of Lani but 3 meters behind Ursula. Let's call Lani z.

L = z

A = z + 5 = y - 3 (since Ursula was "y" and Alma finished 3 meters behind Ursula)

We're going to leave Carly until the end since she finished halfway between the first and the last girls.

Now we can see that Alma is represented by equations with 3 different letters:

A = x = z + 5 = y -3

Therefore we know that

x = y -3

⇒A = y - 3

And we'll proceed to express all the other girls distances in terms of "y"

We know that Isabel = x - 7. Therefore we can substitute x = y - 3 and we get that

Isabel = x - 7 = (y - 3) - 7 = y - 10

⇒I = y - 10

We already have Ursula and Betty expressed in terms of y.

⇒U = y

⇒B = y - 12

Now let's go back to Alma equation (A = x = z + 5 = y -3) and we see  that:

z + 5 = y - 3.

Therefore z = y - 3 - 5 = y - 8.

⇒z = y - 8

We have Lani left who was L= z = y - 8

⇒ L = y - 8

The first girl would be Ursula = y

And the last girl would be Betty = y - 12.

⇒Therefore, Carly finished halfway them both and that would be C = y - 6

So, the order in which they arrived was:

Ursula = y

Alma = y - 3 (3 meters behind)

Carly = y - 6 (3 meters behind Alma)

Lani = y - 8 (2 meters behind Carly)

Isabel = y - 10 (2 meters behind Lani)

Betty = y - 12 (2 meters behind Isabel)

Answer:

  C.  -32

Step-by-step explanation:

Using the rule of exponents for a power of a power, we can simplify the expression like this:

  (-8)^(5/3) = ((-8)^(1/3))^5 = (-2)^5 = -32

A suitable calculator can evaluate this for you.

Additional comment

Some calculators use logarithms to compute powers. The logarithm of a negative number is undefined, so direct computation of this expression would give an error on such a device. You would have to recognize that the root and power are odd, so the result will be negative. Then you could calculate -(8^(5/3)) without error.

The rule of exponents used here is ...

  (a^b)^c) = a^(bc)

Answer/Step-by-step explanation:

When you have one or more parentheses inside a parentheses you change it to bracket so it is easier to tell which parentheses belongs to which.

Instead of ((-2+5)x4), it would be [(-2+5)x4]

Step-by-step explanation:

Answer:

-3/4

Step-by-step explanation:

a = 2 and b = -1

12a⁻⁴b⁻³

= 12(2)⁻⁴(-1)⁻³

= 12(1/16)(-1)

= -12/16

= -3/4

The area of the triangle is 2√5 square units

The formula for finding the area of a triangle is expressed as:

A = 0.5bh

b is the base

h is the height of the triangle

Using the distance formula

b = AC = √(5-1)²+(0-2)²

base =√20
base = 2√5

For the height

h = √(1-3)²+(4-4)²

base =√2²
base = 2

Area = 0.5(2)(2√5)

Area = 2√5 square units

Hence the area of the triangle is 2√5 square units

Answer:

the answer is C

Step-by-step explanation:

I had the same question

Step-by-step explanation:

The slope of 3 and -10.

If the slope is above 0, the line is increasing.

If the slope is at 0, it's a horizontal line or straight. Vertical If the run is 0.

If the slope is below 0, the line is decreasing.

3 is slanting upward, the slope is greater than 0 therefore the line is increasing.

-10 is slanting downward, the slope is less than 0 therefore the line is decreasing.

Answer:

x = 2[tex]\sqrt{6}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² = ([tex]\sqrt{12}[/tex] )² + ([tex]\sqrt{12}[/tex] )² [ the 2 legs are congruent ]

x² = 12 + 12 = 24 ( take square root of both sides )

x = [tex]\sqrt{24}[/tex] = [tex]\sqrt{4(6)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{6}[/tex] = 2[tex]\sqrt{6}[/tex]

Answer:

a. Kito has been billed correctly

Step-by-step explanation:

We simply need to check Kito's work to see if his price is accurate.

First, we can add the prices together to find the price before the sales tax is applied:  39.99 + 24.99 + 26.99 = $91.97

We can use this formula to figure out the total cost, C, after the sales tax, t is added:

C = l + (l * (t / 100)), where l = the price before applying the sales tax

C = 91.97 + (91.97 * (6 / 100)) = 97.4882 = $97.49

We know that the total cost lies between the 50 and 100 and that Kito chose the express shipping.  Thus we add:  97.49 + 8.20 = $105.69.

If we did not round before, we would still get the same answer when rounding:  97.4882 + 8.20 = 105.6882 = $105.69

Kito has not been charged enough for his purchase.

Option B is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example: so

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

First, we need to calculate the total cost of the purchase before shipping and taxes:

= $39.99 + $24.99 + $26.99

= $91.97

Next, we need to add the shipping cost based on the amount of the purchase:

Since the purchase amount is between $50 and $100, the express shipping cost is $8.20.

So the total cost of the purchase with shipping is:

= $91.97 + $8.20

= $100.17

Finally, we need to add the tax:

= 6% of $100.17

= $6.01

So the total amount Kito should be billed is:

= $100.17 + $6.01

= $106.18

And,

Since Kito was billed $105.69, he has been undercharged by $0.49.

Therefore,

Kito has not been charged enough for his purchase.

It is true about Marcy's survey that she wants to study all visitors of the library and due to this, her sample is not representative.

Marcy's study focuses on determining the type of books that visitors prefer to borrow. Based on this, Marcy is studying the preferences of all the visitors to the library.

The sample selected is not representative because she is only considering those that go to the children's room on a specific day and time of the week rather than all the visitors.

Based on this, it can be concluded her population is all visitors and the sample is not representative.

Note that I think it is the question in the math book.

Its says... (from what I see in my book)

A) Marcy’s sample is not a representative sample because not all of the  library’s visitors go to the children’s reading program.

B) Marcy’s sample is a represnetative sample of the population.

C) Marcy will get a random sample by surveying as many people in the children’s reading room as possible.

D) The population of Marcy’s study consits of all visitors of the public library.

E) The results of Marcy’s survey include a mode, but niether a mean nore a median.

The answers that are true are

A

D

E

Why?

Let’s take letter b for example. It says that Marcy’s sample is a representative sample of the population. This is wrong because she asked all the people in the children’s reading room and that is not the whole population

*Note that the whole population is the people in the library*

Marcy needs to ask people who are in and not in the children’s reading room.

Answer:

Step-by-step explanation:

x + 70 = 180   {Linear pair}

       x = 180 - 70

       x = 110

y + 82 = 180 {linear pair}

      y = 180 -82

      y = 98

x - 4 = 110 - 4 = 106

2y - 40 = 2*98 - 40

            = 196 - 40
