Answer:

22

Step-by-step explanation:

When youre trying to find a fraction of a number, you can divide the number by the fraction.

For instance:

1/3 of 66: 1/3 × 66 = 22

1/2 of 66: 1/2 x 66 = 33

Answer:

117

Step-by-step explanation:

270 -153=117

Step-by-step explanation:

1 face area = length x width (aka length x length since cube)

therefore 1 side = ±√144 cm = 12 cm or - 12cm (rej as length > 0cm)

volume = length x width x height = 12 x 12 x 12 = 1728cm^3

Answer:

2/5

Step-by-step explanation:

4+19=25

square root of 25 is 5 so

adjacent over hypotenuse is 2/5

this might be wrong but I think this is how u do it

Answer:

just follow this formula

cos=adjacent over (divided by) hypothenuse

Step-by-step explanation:

1. You have a ladder that is 10 feet tall and you place it on the ground 6 feet away from your house, which you plan to paint. How far up will the ladder reach? (Ans: 8 feet)

2. I think drawing a diagram of this is pretty self-explanitory. Just remember to lable the ladder as 10 feet, the ground as 6 feet, and the house as 8 feet.

3. There wasn't really an equation in the question, but if you draw a triangle you'll need to solve for the third side. It would be 8 feet, but if you consider the pythagoran therom:

100ft(c^2, the hypotenuse, or the ladder)- 36 ft(a^2, or the ground)= 64, the square root of 64 would give you 8. You can write it out symbolically, but I'm typing and there's not much I can do on here.

Answer:

  0.6

Step-by-step explanation:

The instantaneous rate of change at any point on a curve is the slope of the tangent line at that point.

At x=1, the tangent line is given as ...

  y = 0.6x +0.9

The slope of that line is the coefficient of x, 0.6.

The instantaneous rate of change of f(x) at x=1 is 0.6.

Answer:

no

Step-by-step explanation:

No, because none of the factors of 29 equal to -1

Answer:

  A)  28

Step-by-step explanation:

Of the seven moves, 3 must be to the left, and 4 must be to the right. That is, we end up exactly one space right of where we started, so there must be exactly one more move to the right than to the left.

The number of permutations of LLLRRRR is 7!/(4!·3!) = 35. Of those, several must be eliminated, because they result in a path that goes off the right side of the board.

The discounted sequences are ...

With these 7 possibilities eliminated from the list, there are 35 -7 = 28 possible paths from P to Q.

Answer:

c = 40 + 50m

Step-by-step explanation:

40 is a constant, it is not affected by the number of months the person works out at the gym for.

There is a monthly fee of $50. So, every month Colton gets charged $50, so this is the variable.

The total cost would be represented by the equation c = 40 + 50m then.

Let's look at this using a number for m.

If Colton went to the gym for 2 months then we can set up the equation like this:

c = 40 + 50(2)

c = 40 + 100

c = 140

Therefore he spends a total of $140 for 2 months.

Hope this helps!

Answer:

4 cups

Step-by-step explanation:

For one batch of cookies you'll need 1/2 cup of sugar. 8 batches of cookies is 8 times the amount of batches of one batch of cookies. So, if the amount of batches is multiplied by 8, then we need to multiply the amount of sugar by 8 as well:

1/2 * 8 = 8/2 = 4/1 = 4

4 cups of white sugar are needed for 8 batches of cookies.

Answer:

[tex]S = -\dfrac{1}{3}P+\dfrac{740}{3}[/tex]

Step-by-step explanation:

Given that:

Number of seats sold is 180 with ticket price $200.

Number of seats decreases by one when the ticket price is increased by $3.

To find:

The formula for the number of seats sold (S) when the ticket price is P dollars.

Solution:

It is linear dependency of number of seats sold, S on ticket price, P.

[tex]S\propto P[/tex]

It can be written as:

[tex]S = kP+C[/tex]

Where [tex]k[/tex] is the constant of proportionality and

[tex]C[/tex] is a constant.

Now, putting the given values:

[tex]180 = 200k +C ..... (1)[/tex]

[tex]179 = 203k+C[/tex] ...... (2)

Subtracting (1) from (2):

[tex]3k = -1\\\Rightarrow k =-\dfrac{1}{3}[/tex]

Putting the value in (1):

[tex]\Rightarrow C = 180+\dfrac{200}{3} = \dfrac{740}{3}[/tex]

Therefore the equation becomes:

[tex]S = -\dfrac{1}{3}P+\dfrac{740}{3}[/tex]

Answer:

I believe you mean algebra and inverses when you change it to solve inequalities.

Step-by-step explanation:

Let's use -3 + 4 as an example. In order to change the function, you will switch the sign. (In this case, we change "+" into ")

At this same time, you must change the sign in front of the numbers. (Positive signs become negative and negative signs become positive.

So, -3 + 4 is the same thing as 3 - -4.

3 - 4 = -1

-3 + 4 = 1

Tip: When subtracting a negative number, the answer is likely to go up instead of down.

I hope this helps! I did my best :)

Answer:

3([tex]\frac{1}{3}[/tex]x+8)=11

Step-by-step explanation:

It says 3 times the sum of one third of a number and 8, so we group that expression into the parentheses. Since there is a key word is, we need to put an equal sign.

Answer:

t = -4

Step-by-step explanation:

[tex]\frac{6 - t}{2}[/tex] = -5

6 - t = 10

-t = 4

t = -4

Answer: Yes

Step-by-step explanation:

The Vertical angle would show that 2 of the angles are exactly the same. Its also given 2 lines that are marked as congurent. Since we know that angle and the lines are congruent we can also say that angle IFJ is congruent to angle IHG meaning that they are congruent because of ASA (Angle Side Angle Theorem)

Congruent triangles have equal corresponding sides lengths and angle measures.

The triangles are congruent by ASA

From the attached figure, we have:

[tex]\mathbf{HI \cong IF}[/tex]

Lines HG and JF are parallel lines.

It means that:

Angles G and F are corresponding, and also angles at I in both triangles are vertical angles.

So, we can conclude that both triangles are congruent by ASA

Time for which Bradly has to mow lawns to get $48:

We know that Bradly earn $3 every 3/4 hours of mowing lawns

Time taken by Bradly to get $1:

time taken by Bradly to get $1 = time taken to get $3 / $3

time taken = (3/4) / 3

time taken = 1/4 hours / dollar

Time taken by Bradly to get $48:

Time taken to get $48 = time taken to get $1 * 48

Time taken to get $48 = 1/4 * 48

Time taken = 12 hours

Therefore, after 12 hours of Mowing lawns, Bradly will have $48

Given that:

Two adjacent terms of an arithmetic sequence are given as 5, 8.

To find:

The next term = ?

Solution:

First of all, let us learn about an arithmetic sequence and its property.

An Arithmetic sequence (sometimes known as Arithmetic Progression or an AP), is a sequence in which there is a common difference between every two terms.

Suppose, an arithmetic sequence is:

[tex]a, b, c, d[/tex]

Then common difference = [tex]b-a=c-b=d-c[/tex]

Let the next term in the given sequence be [tex]x[/tex].

Then as per the property of an Arithmetic sequence, we can say:

[tex]8-5=x-8\\\Rightarrow x=3+8\\\Rightarrow x =\bold{11}[/tex]

Therefore, the answer is: 11

Answer:

$600

Step-by-step explanation:

first, you need to find the unit price which is found by dividing 720 by 6.

so, 720/6 is 120

then, to find the cost of 5 notebooks, you just need to multiply 120 by 5

which would get you 600.

therefore, the total cost of 5 notebooks is $600.

i hope that helps :)

Answer:

600

Divide 720 from 6

= 120

120 x 5 = 600
