03. as a percent is 30%

1.5% as a decimal is 0.75

3/4 x 80 is 60.

4 2/3 divided by 1/2 is 1.5...

Answer:

27 = 30%

28 = 0.15

29 = 60

30 = 14

Step-by-step explanation:

When you convert a decimal to a percentage, if it is set up with "0." in front, then just swap the number behind the decimal and put it in front of the zero and add a percentage sign. When converting a percentage to a decimal, you reverse the process. Then the others are simple multiplication and division! Remember, when you're dividing a fraction, use the process "KCP" (keep change flip) where you keep the first fraction in the equation, change the division sign to a multiplication sign, and flip the next fraction. (ex. 1/2 flipped to 2/1.) Then just multiply.

The distance between the boats after 1 minute is 17 ft

Step-by-step explanation:

Here, we want to calculate the distance between the boats after 1 minute

The distance covered by the first boat after 1 minute is 2 feet while for the second it is 1 foot

So for the first boat, it has 8 ft ahead, for the second boat, it has 9 ft ahead

So the distance between the two after 1 minute will be 9 ft + 8 ft = 17 ft

Step-by-step explanation:

This applies to your exam.

The variable expression Nemo could have written either "7x" or "x * 7" to represent "the product of a number and 7."

We have,

Nemo could have written the following two correct variable expressions to represent the phrase "the product of a number and 7":

= 7x

In both expressions, "x" represents the unknown number, and the product of "x" and 7 is obtained by either multiplying "x" by 7 (7x) or by multiplying 7 by "x" (x * 7).

Both expressions are equivalent and correctly represent "the product of a number and 7."

Thus,

The proof of every positive integer k that divides the order of g, there exists a subgroup h of g of order k is shown below:

A subgroup is a group nested inside another group. The subgroup test is used on subsets of a group to determine if they are subgroups. A proper subgroup is a subgroup that does not contain all of the original group, while a trivial subgroup contains only the identity.

Suppose k ∣ g ⟹n=dk:

If h(g)=⟨g⟩ is cyclic then

clearly K:=|⟨g^d⟩|=k .

Suppose now we have

1≠H≤h(g),

|H|=k and

let r>0 be the minimal natural number s.t.

g^r ∈ H , then

1=(g ^ r)^k = g^(r k)

⟹n ∣ r k ⟹ r k=ns =d ks ⟹ r= ds ⟹ s ∣ d

and from here we have

g^ r=(g^ d)^ s ∈K

Also,  |H|=||K|

we get equality and thus uniqueness of K.

Answer:

I think the school is located at (0,4).

Step-by-step explanation:

I graphed the equation in my graphing calculator and it came up with a kind of v shaped graph. If you look at the question and see that we first house to school, that would probably mean from the left side of the graph to the center (0,4). Then we go from school to friend's house, so it must be from the center to the right side of the graph. Therefore, the school must be the y intercept (0,4) as that is the center of the graph.

Answer:

(3,0)

Step-by-step explanation:

y= 2/3x - 2 ... (1)

y= -x+3 ... (2)

First, change the equations into normal equation form

(1): - 2/3x + y= - 2

(2): x+y= 3

(1)×3: - 2x+3y= - 6 ... (3)

(2)×2: 2x+2y= 6 ... (4)

(3)+(4): 5y=0

y= 0

Substitute y=0 into any equation

Let's say, equation (2)

y= -x+3

0= -x+3

-3= -x

x= 3

Answer:

means it is your as u know u are a ashile

Answer:

We have the system:

3y>2x+12

2x+y≤-5

The first step will be to write the inequalities as lines:

y  > (2x + 12)/3

y ≤ -5  - 2 x

Now that the equations are written in slope-intercept form, we just need to draw the lines.

In the first case, we have the symbol ">", which means that the line will be a dashed line, and the shaded area will be above that line.

In the second equation we have the symbol "≤", this means that the line will be a solid line, and the shaded area will be below that line.

The graph of both inequalities is shown below. Where the solution to the system is the double shaded area.

Answer:

Thanks to Facundo doing all the work, all I did was plug in the numbers on a graphing calculator.  

Step-by-step explanation:

Using the graphing calculator, "y>(2x+12)/3" has points at (-6,0) and (0, 4) and isn't shaded because there isn't a line under the greater than/less than sign.

Using the graphing calculator again, we plug in the inequality "y≤-5-2x". This has points at (-5, 0) and (0, -5) and is shaded because there is a line under the greater than/less than sign. A picture of this is attached.

Again, thank you Facundo. Refer to his explanation to find out how to make the inequalities lines.

Answer:

We conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.

Step-by-step explanation:

We know that the perimeter of a rectangle = 2(l+w)

i.e.

P = 2(l+w)

Here

Given that the length and width of the playground by a scale factor of 2

A scale factor of 2 means we need to multiply both length and width by 2.

i.e

P = 2× 2(l+w)

P' = 2 (2(l+w))

    = 2P      ∵ P = 2(l+w)

Therefore, we conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.

Answer:

y < 3x + 5: No

y = 3x + 5: No

y > 3x + 5: Yes

Step-by-step explanation:

You can just put the value of x which is (-2) into each equation to see if the y value would be 4.

y < 3x + 5

y < 3(-2) + 5

y < -6 + 5

4 < -1 (This equation is wrong, so the point does not satisfy this equation)

y = 3x + 5

y = 3(-2) + 5

y = -6 + 5

4 = -1 (This equation is wrong, so the point does not satisfy this equation)

y > 3x + 5

y > 3(-2) + 5

y > -6 + 5

4 > -1 (This equation is correct, so the point does satisfy the equation)

Answer:

The equation in slope-intercept form will be:

Step-by-step explanation:

Given

We know that the slope-intercept form of the line equation is

[tex]y = mx+b[/tex]

where m is the slope of the line and b is the y-intercept

substituting m = -2 and the point (5, 4) in the slope-intercept form to get the y-intercept 'b'

y = mx+b

4 = -2(5) + b

4 = -10 + b

b = 4+10

b = 14

now substituting m = -2 and b = 14  in the slope-intercept form to get the equation in slope-intercept

y = mx+b

y = -2x + 14

Therefore, the equation in slope-intercept form will be:

Answer:

1 foot away from motion detector

Step-by-step explanation:

Given that:

Initial Position = 5 feets away from detector

Distance moved away = 0.5ft/sec for 4 seconds ; distance moved away = 0.5 * 4 = 2 feets

Total distance away = 5 feets + 2 feets = 7 feets

Distance moved towards motion detector :

-2 ft/sec for 3 seconds ;

Distance = speed * time

Distance moved = (-2ft/sec * 3) = - 6 feets

Hence, distance in feets from motion detector :

7 feets - 6feets = 1 feet away from motion detector

Step-by-step explanation:

Total number of cards in a standard deck = 52

Number of hearts in the deck = 13

Number of clubs in the deck = 13

Number of diamonds in the deck = 13

Number of spades in the deck = 13

Four cards are drawn at random by Timothy.

These four cards are drawn from each one of the suits.

And the cards are not replaced.

Therefore, now cards remaining in each suit:

Remaining number of hearts in the deck = 12

Remaining number of clubs in the deck = 12

Remaining number of diamonds in the deck = 12

Remaining number of spades in the deck = 12

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Here, number of favorable cases are 12 (i.e. number of hearts)

Total number of cases = 12 [tex]\times[/tex] 4 = 48

Therefore, the required probability is:

Answer:

5/2 cups of warm water

Step-by-step explanation:

Recipe for homemade slime solution

Warm water : cups of soap

5/3 : 1/3

if she has 2/4 cup of soap how many cups of warm water will she need

Let

x = cups of warm water she will need

Warm water : cups of soap

x : 2/4

Equate the two ratios

5/3 : 1/3 = x : 2/4

5/3 ÷ 1/3 = x ÷ 2/4

Cross product

5/3 * 3/1 = x * 4/2

15/3 = x * 2

5 = 2x

Divide both sides by 2

x = 5/2 cups

She will need 5/2 cups of warm water
