Height of wall = 10ft

Length of ladder = 12ft

Angle of elevation be x

Sin x = opp/hyp

Sin x = wall height/length of ladder

Sin x = 10/12

Sin x = 0.83

X = Sin-¹ (0.83)

X = 56.44°

Option C

For x = 1.5 we get f(x) = -2

Solution:

Given function is:

[tex]f(x) = 3.4x - 7.1[/tex]

We have to find the value of "x" so that f(x) = -2

Substitute f(x) = -2 in given function

[tex]-2 = 3.4x - 7.1[/tex]

Solve for "x" by moving the constants to one side and variables to other side

[tex]3.4x = -2 + 7.1\\\\3.4x = 5.1\\\\ \text{Divide both the sides of equation by 3.4 }\\\\x = \frac{5.1}{3.4}\\\\x = 1.5[/tex]

For x = 1.5 we get f(x) = -2

We can verify by substituting x = 1.5 in given function

[tex]f(1.5) = 3.4(1.5) - 7.1\\\\f(1.5) =5.1-7.1\\\\f(1.5) = -2[/tex]

Thus for x = 1.5 we get f(x) = -2

The maximum number of pages for which the time to print at Jerry's Print Shop is less than at Joe's Print Shop is 14.

This question deals with comparing two linear equations [tex]t1 = 45 + 5p[/tex] for Joe's Print Shop and t2 = 30 + 6p for Jerry's Print Shop. To determine the maximum number of pages (p) where Jerry's shop is quicker than Joe's, we need to find the value of p where t2 < t1.

Setting the two equations equal to each other, we get:

[tex]45 + 5p = 30 + 6p,[/tex]

Solving this equation, we find that p = 15.

However, p=15 is when the time at both shops is the same. Since we want the number of pages for which Jerry’s is less than Joe's, we should choose the next value lower, which is p=14.

Answer:

D.Train A by a factor of 1.1

Step-by-step explanation:

Answer:

m∠DEC = 123°

Step-by-step explanation:

First we need to solve for x the equation: x = (x - 45) + (x-12)

x = (x - 45) + (x-12) ⇔ x = 2x -57 ⇔ 0 = x - 57 ⇔ x = 57

since m∠DEC = 180 - x  then   m∠DEC = 180 - 57 = 123

Answer:

Step-by-step explanation:

1) pentagon; n= 5

Sum of interior angles = 180*(n -2) = 180* (5-2) = 180 * 3 = 540

2) Sum of interior angles of a polygon = 1080

180*(n-2) = 1080

n - 2 = 1080/180

n -2 = 6

n = 6+2

n = 8

Polygon has 8 sides

3) Sum of interior angles of a polygon = 6840

180*(n-2) = 6840

n - 2 =6840/180

n -2 = 38

n = 38 + 2

n = 40

Polygon has 40sides

4)Sum of interior angles of an octagon = 180*(n-2) = 180* (8-2) = 180 - 6 = 1080

The sum of the interior angles of the 10-sided polygon on the left is 1440 °.

Hope this helps!

The problem is a mathematical exercise in determining the total number of movies rented from the provided percentage of those returned. By setting up an equation and solving it, we find that the total number of movies rented was 700.

The student's question is on a mathematical concept related to percentages and determining the whole from a percentage portion. From the information provided, 434 movies, which represent 62% of the total number of movies rented last week, were returned. To calculate the total number of movies rented, we can let the total be x. With this, the equation representing the scenario is 0.62x = 434.

By solving for x, we get x = 434 / 0.62. After the calculation, we find that the total number of movies rented last week was 700. Therefore, the store originally rented out 700 movies.

Remember that when dealing with percentages, the percentage value (in this case, 62%) must be converted into decimal form before performing any calculation. This is done by dividing the percentage by 100, thus 62% becomes 0.62. For clarity, here's the step-by-step procedure:

the Distributive Property uses two operations: multiplication and addition. It is an essential key to success in algebra. The Distributive Property allows you to "distribute" a number to each of the addends within parentheses. It offers another way of solving a problem.

Answer:

A math property.

Step-by-step explanation:

Say you have a two big number and you don't know the answer on top of your head. You use distributive property to break it apart.

Answer:

Step-by-step explanation:

72%

Answer: 72%

Step by Step Explanation:

1. We assume, that the number 25 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 25, so we can write it down as 100%=25.

4. We know, that x% equals 18 of the output value, so we can write it down as x%=18.

5. Now we have two simple equations:

1) 100%=25

2) x%=18

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=25/18

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 18 is what percent of 25

100%/x%=25/18

(100/x)*x=(25/18)*x       - we multiply both sides of the equation by x

100=1.38888888889*x       - we divide both sides of the equation by (1.38888888889) to get x

100/1.38888888889=x

72=x

x=72

now we have:

18 is 72% of 25

Answer:

Step-by-step

let c be the total number of cartoons

Cost of purchase = 50c

total sale price = 100(c-15)

profit = total sale price - cost of purchase    

        = 100(c-15) - 50c = 2250 cents

Then (100c-50c) - 1500 = 2250

then 50c = 3750

Then c = 3750/50 = 75

Option a

- x + 2y = −10

3x − y = 12

Step-by-step explanation:

step 1

Find the equation of the line with negative slope

we know that

The line with negative slope has a y-intercept at (0,-5)  and passes through the point (2,-6)

Find the slope

[tex]m=(-6+5)/(2-0)=-\frac{1}{2}[/tex]

The equation in slope intercept form is

[tex]y=-\frac{1}{2}x-5[/tex]

Convert to standard form

Multiply by 2 both sides

[tex]2y=-x-10\\x+2y=-10[/tex]

step 2

Find the equation of the line with positive slope

The line with positive slope has a x-intercept at (4,0)  and passes through the point (2,-6)

Find the slope

[tex]m=(-6-0)/(2-4)=3[/tex]

The equation of the line in point slope form is equal to

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=3\\point\ (4,0)[/tex]

substitute

[tex]y-0=3(x-4)[/tex]

Convert to standard form

[tex]y=3x-12\\3x-y=12[/tex]

Step-by-step explanation:

I used a calculator

Answer:

45°

Step-by-step explanation:

We know ∠ Y +∠ S = 90

and ∠ S= 5 ( ∠ Y)-180  so

leave S alone for both

90- ∠Y = 5 ( ∠Y) -180

270 = 6( ∠Y )

45= ∠ Y

∠S = 5( 45) -180

     =225-180

     =45

Final answer:

The measure of angle Y (m∠Y) is 45°, following the equation derived from the facts that angles S and Y are complementary and m∠S equals 5 times m∠Y minus 180°.

Explanation:

If ∠S and ∠Y are complementary angles, then the sum of their measures is 90°. According to the given information, m∠S = 5(m∠Y) − 180°. Since m∠S + m∠Y = 90°, we can set up the equation:

5(m∠Y) − 180° + m∠Y = 90°

Combining like terms to solve for m∠Y:

6(m∠Y) = 90° + 180°

6(m∠Y) = 270°

m∠Y = 270° / 6

m∠Y = 45°

The measure of angle Y, m∠Y, is 45°.

Option A

[tex]\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}} = \left(y^{2}\right)^{\frac{-1}{2}}[/tex]

Solution:

Given expression is:

[tex]\left(y^{\frac{4}{3}} \cdot y^{\frac{2}{3}}\right)^{\frac{-1}{2}}[/tex]

Product of powers property:

The product of powers property tells us that when you multiply powers with the same base you just have to add the exponents

Which is represented as,

[tex]a^m.a^n = a^{m+n}[/tex]

Therefore, the given expression becomes,

[tex]\left(y^{\frac{4}{3}+\frac{2}{3}}\right)^{\frac{-1}{2}}[/tex]

Now add the exponents, we get

[tex]\left(y^{\frac{4+2}{3}}\right)^{\frac{-1}{2}}[/tex]

Simplify the above expression

[tex]\left(y^{\frac{6}{3}}\right)^{\frac{-1}{2}}[/tex]

Simplify the exponent of y, we get

[tex]\left(y^{2}\right)^{\frac{-1}{2}}[/tex]

Thus Option A is correct

Answer:

The answer is A

Step-by-step explanation:

The total cost which includes tip, food cost without tax and sales tax for the considered situation is 19.63 bucks approximately.

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For this case, we're specified that:

Pizza cost = 15.95 +7% of tax on 15.95 bucks

Tip  = 15%  of pizza cost

Total cost = Pizza cost + tip

7% of 15.95 is: [tex]\dfrac{15.95}{100} \times 7 = 1.1165[/tex] bucks

Thus, pizza cost = The  (15.95 + 1.1165) = 17.0665

Tip price = 15% of 17.0665 = [tex]\dfrac{17.0665}{100} \times 15 \approx 2.56[/tex] bucks.

Thus, total cost ≈ 17.0665 + 2.56 ≈ 19.63 bucks

You can park in the garage for 5 hours 30 minutes

Solution:

Given that, shopping mall parking garage charges $2 for the first half hour and $1.20 for each additional half hour (even if it is under 30 minutes)

Therefore,

Cost for first half an hour = $ 2

Cost for each additional half an hour = $ 1.20

Let "x" be the number of each additional half hour

Therefore, total cost to pay is given as:

Total cost = Cost for first half an hour + (Cost for each additional half an hour)(number of each additional half hour)

Total cost = 2 + 1.20x

Given you have $ 8 in cash

[tex]8 = 2 + 1.20x\\\\1.20x = 8 - 2\\\\1.20x = 6\\\\x = \frac{6}{1.20}\\\\x = 5[/tex]

Total hours parked = first half an hour + 5
