The top of a 22-foot ladder rests against the top of an 18-foot wall. If the base of the ladder is on the same ground level as that of wall, what angle does the ladder form with the ground? Express your solution to the nearest degree.

Answers

Answer 1
use the sine ratio here:-   sin = opposite / hypotenuse so 
sin A =   18/22 

A =  54.9 degrees  

55 to nearest degree
Answer 2

Answer:

Step-by-step explanation:

Given that The top of a 22-foot ladder rests against the top of an 18-foot wall.

The ladder, the wall and the floor together make a right angled triangle with hypotenuse as ladder.

Thus we have a right triangle with hypotenuse = 22 ft

and the side of the wall = 18

The required angle is the angle  the ladder form with the ground.

Hence we have if x is the angle

[tex]sin x =\frac{Opposite}{Hypotenuse} =\frac{18}{22}[/tex]

From this we can find the angle X

X = sin inverse of 18/22

X=54.9

Round it off to X=55 degrees

in six years, clem kadiddlehopper will be 5 times as old as he was 26 years ago how old is he now?

Answers

x=clem's age now
in 6 years, he will be x+6 years old
that is 5 times as old as 26 years ago or when he was x-26 years old

so
x+6=5(x-26)
distribute the 5
x+6=5x-130
minus x both sides
6=4x-130
add 130 from boths ides
136=4x
divide both sides by 4
34=x
x=34
he is 34 now
Final answer:

The question involves setting up an equation to determine Clem Kadiddlehopper's current age based on his age in six years and 26 years ago. By solving the equation x + 6 = 5(x - 26), we find that Clem is currently 34 years old.

Explanation:

Explanation:

The question asks us to determine Clem Kadiddlehopper's current age based on information about his age in future and past years. Let's define Clem's current age as x years old.

In six years, he will be x + 6 years old. It is stated that in six years, Clem will be five times as old as he was 26 years ago. Since 26 years ago he was x - 26 years old, we can write the equation: x + 6 = 5(x - 26).

To find Clem's age, we will solve the equation:

x + 6 = 5(x - 26)x + 6 = 5x - 1304x = 136x = 34

Therefore, Clem Kadiddlehopper is currently 34 years old.

Jay went to an amusement park. The park charges an entrance fee of $10.50 and $4.50 for every ride. Jay spent $46.50 on entrance fees and rides. Which fuction can be used to find the number of rides he went on?

Answers

The function to find the number of rides Jay went on is [tex]\( 10.50 + 4.50x = 46.50 \)[/tex]

Let x be the number of rides Jay went on.

The cost of the entrance fee is $10.50, and the cost per ride is $4.50. The total amount Jay spent is $46.50. The equation representing this scenario is:

[tex]\[10.50 + 4.50x = 46.50\][/tex]

To find the number of rides, you can solve for x:

1. Subtract the entrance fee from the total amount:

  [tex]\[ 46.50 - 10.50 = 36.00 \][/tex]

2. Divide by the cost per ride:

 [tex]\[ \frac{36.00}{4.50} = 8 \][/tex]

So, Jay went on 8 rides.

The function to find the number of rides x is:

[tex]\[f(x) = 10.50 + 4.50x\][/tex]

Setting this equal to the total expenditure ($46.50), the function to find x is:

[tex]\[10.50 + 4.50x = 46.50\][/tex]

The formula for glue says to add 50ML
of hardener to each container of resin. How much hardener should be added to 15 containers of resin?

Answers

Since it's 50mL of hardener added in ONE container of resin, you multiply 50 and 15
50mL times 15= 750mL
Hope this helps.

Final answer:

To find out the total hardener needed for 15 containers of resin, multiply 15 by the amount per container, 50ML, which equals 750ML of hardener in total.

Explanation:

To calculate the total amount of hardener needed for 15 containers of resin, we use a simple multiplication. We have been given that each container requires 50ML of hardener. Therefore, we multiply the number of containers by the amount of hardener needed per container.

Calculation:
Number of containers × Amount of hardener per container = Total amount of hardener
15 containers × 50ML/container = 750ML

Thus, for 15 containers of resin, you would need to add a total of 750ML of hardener.

First remove the parenthesis. 
5/6 - 2/3
Then we want the least common denominator which is 6 because 2 * 3 = 6.

AC = 4 (sin80)/ sin20
AC = 4(0.98) / (0.34)
AC = 3.92 / 0.34
AC = 11.52

answer

C.11.52 centimeters

Answer:

C.11.52 centimeters

Step-by-step explanation:

Given,

In triangle ABC,

BC = 4 centimeters, m∠B = m∠C, and m∠A = 20°.

Since, the sum of all interior angles of a triangle is supplementary,

⇒ m∠A + m∠B + m∠C = 180°

⇒ 20° + m∠B + m∠B= 180°

⇒ 2 m∠B = 160°

⇒ m∠B = 80°,

Now, By the law  of sines,

[tex]\frac{sin A}{BC}=\frac{sin B}{AC}[/tex]

By cross multiplication,

[tex]sin A\times AC = sin B\times BC[/tex]

[tex]\implies AC = \frac{sin B\times BC}{sin A}[/tex]

By substituting values,

Okay. So, there are 12 blue tickets and 20 red tickets, which makes 32 total tickets in the bag. 12/32 tickets in the bag are blue, and we can simplify that fraction. 12/32 is less than 1/2, so A and D are both eliminated. 12/32 is 3/8 simplified. There is 3/8 of a chance that a blue ticket will randomly be selected from the bag. The answer is C.

In a right triangle, he measure of one acute angle is 3 times the sum of the other acute angle and 8, Find the measure of angle 1 and 2

Answers

Let the acute angles be x and y respectively.  x= 3(y+8).

The sum of the interior angles of a triangle is always 180 degrees.  Therefore, 90 + y + 3(y+8) = 180, and so y + 3y + 24 = 90  =>  4y= 66, and y = 66/4 = 16.5 degrees.

Let's check:  If we're right, then y + 3(y+8) = 90
                                                16.5 + 3(16.5 + 8) = 90  ?
                                                 Yes.  (check it yourself)

Thus, the 3 angles of this right triangle are 90, 16.5 and 73.5; they add up to 180 degrees.

The measure of angles 1 and 2 are 16.5 and 73.5 respectively.

The sum of the two acute angles is complementary.

Let the complementary acute angles be x and y

Since they form a right angle triangle, hence;

x  + y = 90 ............................. 1

If the measure of one acute angle is 3 times the sum of the other acute angle and 8, this is expressed as x = 3(y + 8)

Substitute the value of x into the equation 1 as shown:

3(y+8) + y = 90

3y + 24 + y = 90

4y + 24 = 90

4y = 90 - 24

4y = 66

y = 66/4

y = 16.5

Get the other acute angle:

x = 90 - y

x = 90 - 16.5

x = 73.5 degrees

Hence the measure of angles 1 and 2 are 16.5 and 73.5 respectively.

Where e is the region that lies inside the cylinder x2 + y2 = 16 and between the planes z = −4 and z = 1?

Answers

Final answer:

The region e refers to the inside of a cylinder defined by x² + y² = 16 and between the planes z = -4 and z = 1. It represents a three-dimensional space bounded both radially, by the cylinder, and vertically, by the planes.

Explanation:

The region described in the question is a cylindrical volume in three-dimensional space. To visualize this region, we remember that the cylinder is defined by the equation x2 + y2 = 16, which is the set of points in the xy-plane that are at a distance of 4 from the origin (since the radius is √16 = 4). This cylinder extends indefinitely in the positive and negative z-directions.

The planes z = -4 and z = 1 act as boundaries in the z-direction, trimming the cylinder down so that we're only considering the portion of the cylinder between these two planes. Thus the region e of interest is the set of points inside the cylinder that lie at a height between z = -4 and z = 1.

This type of region is common in problems involving volume calculations, especially when using integral calculus to determine the volume of the shape or when analyzing physical phenomena like fluid flow or electric fields within prescribed bounds.

You buy a pair of jeans at a department store.

What is the percent of sales tax to the nearest tenth of a percent?

The price of the jeans includes a 60% markup. After the discount, what is the percent of markup to the nearest percent?

Answers

The price of the jeans before the discount is $24.99. The sales tax rate is 6.5%. The percent of markup after the discount is 27.7%.

The price of the jeans before the discount can be found by dividing the total cost by the markup percentage plus 100% and then multiplying by 100%.

So, the price of the jeans before the discount is (39.99 / 160) * 100 = 24.994375.

Next, to find the sales tax, multiply the subtotal by the sales tax rate.

The sales tax rate can be found by dividing the sales tax amount by the subtotal and then multiplying by 100%.

So, the sales tax rate is (1.95 / 29.99) * 100 = 6.502167.

To find the percent of markup after the discount, divide the difference between the total cost and the price before the discount by the price before the discount and then multiply by 100%.

So, the percent of markup after the discount is ((31.94 - 24.994375) / 24.994375) * 100 = 27.67322.

The probable question may be:
