During a weekend sale, a store sold 85 DVDs for $19 each. What is the total amount of money, rounded to the nearest hundred, the store made by selling DVDs?

Answer:Options 'A' and 'C' are correct.

Step-by-step explanation:

Let the number of sheep be 's'.

Let the number of goats be 'g'.

According to question, we have given that

the number of sheep and goats are not more than 43.

The number of goats are fewer than 22.

So, the inequalities would be

[tex]g<22\\\\and\\\\s+g<43[/tex]

Hence, Options 'A' and 'C' are correct.

The two inequalities for Harold's sheep and goats situation are A. g < 22 and C. s + g ≤ 43.

To represent the situation described about Harold's sheep and goats, we need to set up two inequalities based on the given information:

Using these inequalities, we can help Harold determine how to distribute his sheep and goats in the new field.

Answer:

The right answer is 3a - 11 ≤ 7 ⇒ 4th answer

Step-by-step explanation:

* Lets study the problem

- From the figure

# The blue line started from 6 and the point is bold that means

   the inequality sign is ≤ or ≥

# The blue line started from 6 and moved to the negative numbers

   that means the inequality is less than or equal

∴ a ≤ 6

* Now lets look to the answers

- There is only one answer has the sign ≤ , the last answer

* Now lets solve it to be sure

∵ 3a - 11 ≤ 7 ⇒ add 11 to the both sides

∴ 3a ≤ 18 ⇒ divide the both sides by 3

∴ a ≤ 6

* The right answer is 3a - 11 ≤ 7

Answer:

86.19°

Step-by-step explanation:

Let x represent the missing value.

The given trigonometric equation becomes:

[tex]\tan x=15[/tex]

We take the inverse tangent of both sides to obtain:

[tex]\tan^{-1}(\tan x)=\tan^{-1}(15)[/tex]

This implies that;

[tex]x=\tan^{-1}(15)[/tex]

We use at least a scientific calculator to evaluate this and obtain:

[tex]x=86.18592517\degree[/tex]

To the nearest hundredth, the missing value is [tex]x=86.19\degree[/tex]

t = 3.1 seconds

Step-by-step explanation:

Set the equation h = -16t^2 + 40t + 30 equal to 0 (0 represents ground level).

Then h = -16t^2 + 40t + 30 = 0

Applying the quadratic formula with a = -16, b = 40 and c = 30,

      -40 ± √( 1600 - 4[-16][30] )

t = -----------------------------------------

                  2(-16)

      -40 ± √ 3520

t = -------------------------

             -32

                                                                               -40 - 59.33

Only the positive t value makes sense.  It is t = ------------------

                                                                                      -32

t = 3.1 seconds

Answer: FIRST OPTION

Step-by-step explanation:

You need the formula for calculate the arc lenght:

[tex]arc\ length=2\pi r(\frac{C}{360})[/tex]

Where  "r" is the radius and and "C" is the central angle in degrees.

You know that the radius is:

[tex]r=7.5[/tex]

And the central angle ∠CAT is:

[tex]C=\angle CAT=125\°[/tex]

Then, you need to substitute these values into the formula  [tex]arc\ length=2\pi r(\frac{C}{360})[/tex] to calculate the length of CT.

Then, this is:

 [tex]arc\ length=CT=2\pi (7.5)(\frac{125\°}{360})[/tex]

[tex]arc\ length=CT=16.4[/tex]

Answer:

The measure of angle EYL is [tex]45\°[/tex]

Step-by-step explanation:

we know that

The measurement of the outer angle is the semi-difference of the arcs which comprises

Let

x-----> the measure of arc EVL

y----> the measure of arc EHL

[tex]m<EYL=\frac{1}{2}(x-y)[/tex]

[tex]m<EYL=\frac{1}{3}(y)[/tex]

so

[tex]\frac{1}{3}y=\frac{1}{2}(x-y)[/tex]

Multiply by 6 both sides

[tex]2y=3x-3y[/tex]

[tex]3x=5y[/tex]

[tex]x=\frac{5}{3}y[/tex] -----> equation A

[tex]x+y=360\°[/tex] -----> equation B  ( is a complete circle)

substitute equation A in equation B

[tex]\frac{5}{3}y+y=360\°[/tex]

[tex]\frac{8}{3}y=360\°[/tex]

[tex]y=(360\°)*(3)/8=135\°[/tex]

Find the value of x

[tex]x=\frac{5}{3}(135\°)=225\°[/tex]

Find the measure of angle EYL

[tex]m<EYL=\frac{1}{2}(x-y)[/tex]

substitute the values

[tex]m<EYL=\frac{1}{2}(225\°-135\°)=45\°[/tex]

Answer:

Step-by-step explanation:

This is a special die.  Its six sides bear the numbers {9, 10, 11, 12, 13, 14}.

There are three possibilities for getting a multiple of two:  {10, 12, 14}, and

there is only one possibilities for getting a multiple of ten:  {10, 12, 14}

The probability here of getting a multiple of two is 3/6, and that of getting a multiple of ten is 1/6.  But one of the outcomes is found in both result sets:  10.  Getting a multiple of 10 is already included in the event that the outcome is a multiple of two.  My answer here would be 3/6, or 1/2.

the probability of rolling a multiple of two or ten is 4/6, which simplifies to 2/3.

The probability of rolling a multiple of two or ten on a die numbered 9 through 14 can be calculated as follows:

First Place Vote: 4x867= 3468

Second Place Vote: 2x301= 602

Third Place Vote: 1x432= 432

3468+602+432= 4502.

Your answer is therefore D.

I hope this helps! :)

Answer:

D) 4502

Step-by-step explanation:

It is given that,

Points for first place = 4 points

Second place = 2 points

Third place = 1 point

Thus, First Place Vote : 4 × 867 = 3468

Second Place Vote: 2 × 301= 602

Third Place Vote: 1 × 432= 432

Thus, Total Points = 3468 + 602 + 432 = 4502.

Hence, last option is correct.

The total surface area for the figures aee;

1) 128 m²

2) 714 in²

1) To find the surface area, we need to find the area of each surface that makes up the object and add together.

Thus:

T.S.A = 4(4 * 4) + (4 * 4) + 4(½ * 4 * 6)

T.S.A = 128 m²

2) The total surface area here is;

T.S.A = 2(15 * 10) + 2(10 * 7) + 2(15 * 7) + 4(4 * 4)

Answer:

a + b = 63

a - b = 12

So, a - b = 12 which can also be written as a = b + 12

Then use substitution and plug in (b + 12) for a in the first equation

(b+12) + b =63

-12              -12

---------------------

2b  =  51 so b=25.5

Now, you know b which can be used to find a

Answer:

x^2 + y^2 + 6x - 8y + 21= 0.

Step-by-step explanation:

The center of this circle is (-3, 4) and the radius id 2.

So in Standard form, the equation is:

(x + 3)^2 + ( y - 4)^2 = 2^2

Converting to General form we have:

x^2 + 6x + 9  + y^2 - 8y + 16 = 4

x^2 + y^2 + 6x - 8y + 9 + 16 - 4 = 0

x^2 + y^2 + 6x - 8y + 21= 0.

1.8y is the answer because first you do 3/4y into a decimals number and then it’s 0.75 then I times it by 2.4 which is 1.8y

To solve the equation 3/4 y = 2.4x for y, we multiply both sides of the equation by 4/3 to eliminate the fraction. Simplifying the equation gives us y = 3.2x. The constant of proportionality in this equation is 3.2.

To solve the equation 3/4 y = 2.4x for y, we need to isolate y on one side of the equation. First, we can multiply both sides of the equation by 4/3 to eliminate the fraction:

3/4 * y = 2.4x

y = (2.4x)/(3/4)

Next, we can simplify the equation by multiplying the numerator and denominator of the fraction by the reciprocal of 3/4, which is 4/3:

y = (2.4x) * (4/3)

y = (9.6x)/3

y = 3.2x

Therefore, the equation 3/4 y = 2.4x can be solved for y to give the expression y = 3.2x. The constant of proportionality in this equation is 3.2, which indicates that y is directly proportional to x with a scale factor of 3.2.

Answer:

5 · a³ · b³ · √5b

Step-by-step explanation:

Start with √(50a^6b^7).  Rewrite 50 as the product of the largest possible perfect square and a multiplier:  50 = 25 · 2.  Then √50 = 5√2.

a^6 is already a perfect square, so find its square root:  √a^6 = a^3.

b^7 = b · b^6, so √b^7 = b^3√b

Now rewrite (50(a^6) (b^7)) as √(50a^6b^7).

Then rewrite √(50a^6b^7) as 5√2 · a³ · b³ · √b.

This latter result can be simplified to 5 · a³ · b³ · √5b

This matches possible answer #1.

Without more information, we cannot give a specific numerical answer for the total interest on a 20-year loan. As a rule, total interest paid will be less on a shorter loan, despite higher monthly payments.

The question is asking how much total interest would Misty pay on a 20-year loan, given she knows the total interest paid on a 25-year loan to be $57,810. We're not given enough information to provide a specific numerical answer for this - the loan interest for a 20-year loan and a 25-year loan involve different payment schedules and amounts - so we can't directly compare or convert the total interest paid.

However, generally speaking, the total interest paid over a shorter loan term (i.e. 20 years) is expected to be less than that of a longer term (i.e. 25 years), assuming all else (loan amount, interest rate) remains equal - this is because the principal balance is being paid down more rapidly, leaving less time for interest to accrue. The trade-off is that monthly payments would be higher on the shorter term loan.

The height of the prism is [tex]1\frac{1}{6}[/tex] units ⇒ answer a

The number of blocks needed is 133 ⇒ answer c

Step-by-step explanation:

* Lets explain how to solve the problem

- The volume of a rectangular prism is

→ V = Area of the base × its height

- The volume of the rectangular prism is [tex]3\frac{25}{36}[/tex] units³

- The area of its base is [tex]3\frac{1}{6}[/tex] units²

- Substitute the values of the volume and area of the base in the rule

∴ [tex]3\frac{25}{36}=3\frac{1}{6}*h[/tex]

- Divide the two sides by [tex]3\frac{1}{6}[/tex]

∴ [tex]h=\frac{7}{6}=1\frac{1}{6}[/tex] units

* The height of the prism is [tex]1\frac{1}{6}[/tex] units

- The volume of each cubic block is [tex]\frac{1}{36}[/tex] units³

- The number of blocks = volume of the prism ÷ volume of the block

∵ The volume of the prism is [tex]3\frac{25}{36}[/tex] units³

∵ The volume of each block is [tex]\frac{1}{36}[/tex] units³

∴ The number of blocks = [tex]3\frac{25}{36}[/tex] ÷ [tex]\frac{1}{36}=133[/tex]

∴ The number of blocks = 133

* The number of blocks needed is 133

What is your question??

The domain is the set of all point where you can evaluate the function.

As you can see, the first piece is defined from -infinity to 2 (included).

The second piece is defined from 2 to 6 (excluded).

The third piece is defined from 6 (excluded) to +infinity.

So, the domain of the function is composed by all the real numbers which are not 6:

[tex](-\infty,6)\cup(6,\infty) = \mathbb{R}\setminus\{6\} = \{x \in \mathbb{R}\ :\ x\neq 6\}[/tex]

As for the range, it is the set of all values taken by the function. We can see that the first piece spans the y axis from 0 to infinity.

The second piece is constantly equal to 2, so it adds nothing.

The third piece spans the y axis from -2 to -infinity, so the range is

[tex](-\infty,-2)\cup[0,\infty) = \mathbb{R}\setminus [2,0) = \{x \in \mathbb{R}\ :\ x\geq 0\ \lor\ x<-2\}[/tex]
