A 5m ladder reaches 4.2m up a wall. What angle does the ladder make with the wall

Answers

Answer 1

Answer:

57.14°

Step-by-step explanation:

A 5m ladder reaches 4.2m up a wall. What angle does the ladder make with the wall?

We solve the above question using the Trigonometric function of Sine

= sin theta = Opposite/Hypotenuse

Opposite = Length of the wall = 4.2m

Hypotenuse = Length of the ladder = 5m

Theta = Angle formed = x

Hence,

sin x = 4.2m/5m

x = arc sin(4.2m/5m)

x = arc sin(0.84)

x = 57.140119621°

Approximately = 57.14°

I need help ASAP find u and v

Answers

Answer:

u = 66

v = 38

Step-by-step explanation:

In a parallelogram, opposite angles are equal.  U is opposite to 66, so it is 66 degrees

In a parallelogram, corresponding angles are supplementary.  180 - 66 = 114

this means that 3v = 114.  114/3 = 38, which is what v is.

okay i don’t know and i’m really sorry

please help me with this i don’t understand it

Answers

Answer:

62

Step-by-step explanation:

119 is adjacent to angle x. angle x and 119=180 (because the angle of a straight line is 180.) which means to find angle x you have to subtract 119 from 180. 180-119=61. because you now know two angles in the triangle you can add the together and subtract them from 180 (remember 180 is what all the angles in a triangle should add up to 180). 61+57=118 and 180-118=62

F is inversely proportional to d^2. When F=9, d=4 Work out d (positive value rounded to 2 DP) when F=6

Answers

Answer:

d = 4.90

Step-by-step explanation:

Given the following data;

F = 9

d = 4

For an inversely proportional relationship, we have;

F = k/d²

Now, we would find the constant, k;

9 = k/4²

k = 9*16

k = 144

Next, to find d, when F = 6

d² = k/F

d² = 144/6

d² = 24

Taking the square root of both sides, we have;

d = 4.90

A pair of jeans is normally priced at $56, but is currently marked down for with a 35% discount. What would replace the B in the proportion? A/B=P/100%

Answers

Answer:

$36.4

Step-by-step explanation:

Given

Cost of Jean = $56

Percent markdown = 35%

Discount = 35% of $56

Discount = 0.35 * 56

Discount = $19.6

New price = $56 - (35% of $56)

New price = $56 - 19.6

New price = $36.4

hence the price that will replace B is $36.4

consider a rectangular prism with length 4 and width and height d

Find an expression for the volume of the prisms in terms of d.

2. compute the volume of the prism when d=1, when d=2, and when d=1/2

Answers

Answer:

Step-by-step explanation:

The expression for the volume of the prisms in terms of d is 4d².

What is a volume?

Volume is the amount of space occupied by a three dimensional shape or object. For a rectangular prism:

Volume = length * width * height

From the diagram, length = 4, width = d, height = d. Hence:

Volume = 4 * d * d = 4d²

When d = 1: Volume = 4(1)² = 4

When d = 2: Volume = 4(2)² = 16

When d = 1/2: Volume = 4(1/2)² = 1

The expression for the volume of the prisms in terms of d is 4d².

A DVD rental service wants to pay close attention to what movies their customers like the most. Which measure of central tendency will give them the best estimate? Explain.

Answers

Answer:

Mode.

Because it is used to determine the most frequently occurring item which in this case is movie.

Step-by-step explanation:

The 3 measure of central tendencies are namely;

Mean, median mode.

- Mean is defined as the average of a set of data.

- Median is the middle term of a set of data that splits that set of data into 2.

- Mode is the term that occurs most frequently in a set of data.

In this question, we want to find the movies most frequently watched.

Thus, from the definitions above earlier, it is clear that the only way to know this is using the mode.

A trader sold a radio set for 72.00 making a profit of 8% .Find , correct to the nearest ghana cedis ,the cost price for the radio set .

Given:

The selling price of a ratio set = 72.00

Profit percent = 8%

To find:

The cost price for the radio set.

Solution:

Let x be the cost price for the radio set.

Radio set is sold at 8% profit.

[tex]\text{Selling price}=x+\dfrac{8}{100}x[/tex]

[tex]\text{Selling price}=x+0.08x[/tex]

[tex]\text{Selling price}=1.08x[/tex]

The selling price of a ratio set is 72.00.

[tex]72=1.08x[/tex]

[tex]\dfrac{72}{1.08}=x[/tex]

[tex]x=66.666...[/tex]

[tex]x\approx 67[/tex]

Therefore, the cost price for the radio set is 67.
