Help!!! Whats X Ive Been Struggling

Answers

Answer 1

Answer:

x = 2

Step-by-step explanation:

GIVEN :-

KJ = 3 unitsQR = 12 unitsJL = x unitsQS = x + 6 units

TO FIND :-

The value of x

SOLUTION :-

To find the value of x , lets assume that both the triangles are similar to each other. As they are similar , their sides are proportional to each other i.e. :-

[tex]\frac{KJ}{JL} = \frac{QR}{QS}[/tex]

[tex]=> \frac{3}{x} = \frac{12}{x + 6}[/tex]

Cross multiply the denominators.

[tex]=> 3(x + 6) = 12 \times x[/tex]

[tex]=> 3x + 18 = 12x[/tex]

Substract both the sides from 3.

[tex]=> 12x - 3x = 3x + 18 - 3x[/tex]

[tex]=> 9x = 18[/tex]

Divide both the sides by 9

[tex]=> \frac{9x}{9} = \frac{18}{9}[/tex]

[tex]=> x = 2[/tex]

Hi there!

[tex] \large{tan35\degree = \frac{x}{16} }[/tex]

We can also use the other angle but I will focus on 35°.

The reason why we use the equation above because tan is equivalent to opposite/adjacent

From the picture, the opposite is x-term while the adjacent is 16 if we focus angle 35°.

Define theta = 35°. Thus, the equation would be tan35° = x/16.

Solving the equation, you might want to bring open Trigonometric Table or a calculator to calculate tan35°. You should get 0.7 (rounded)

[tex] \large{0.7 = \frac{x}{16} }[/tex]

Then solve the equation for x-term.

[tex] \large{0.7 \times 16 = x} \\ \large{x = 11.2}[/tex]

Hence, the value of x is 11.2

Answer

11.2

Questions about the problem be asked through comment.

Furthermore, you can also use the other angle. If we use 55° instead, the equation would be tan55° = 16/x. The outcome would be the same.

Hope this helps, and Happy Learning! :)

The elevation at ground level is 0 feet. An elevator starts 90 feet below ground level. After traveling for 15 seconds, the elevator is 20 feet below ground level. Did the elevator travel up or down? What was the speed (in ft per second) of the elevator in the 15 second interval?

This is due at 8am tomorrow please help me

Answers

The answer is -4 2/3

Explanation : The elevator is at 0, and went below ground level 90 feet, that would be -90, then it went up 20 feet, which would be -90 + 20 = -70

-70 ft / 15sec = - 4 2/3

I am not sure about the ground level and negative difference but that it is what I was taught. Below ground level is negative and above is positive. Therefore the elevator traveled up and it traveled -4 2/3 per second.
It so either 4 2/3 or - 4 2/3 but pretty sure it is - 4 2/3.

A hockey goalie got shot on 18 times . She saved 10 of the shots . Which ratio represents the amount of shots that went in to the amount of shots she saved ?

Answers

Answer is   4:5

========================================================

Explanation:

She saved 10 shots out of 18 total, so that means 18-10 = 8 shots went in.

That forms the ratio 8:10 where we list the amount of shots that went in, followed by a colon, then the amount of shots that were saved. The order is important. From here, we divide both parts of the ratio by 2. The ratio 8:10 fully reduces to 4:5

Effectively, this means that for every 4 shots that went in, there were 5 shots that were blocked.

4:5

Saved shots: 10
Shot in: 8
8:10 -> 4:5 (simplified)

The control limits, calculated as three standard deviations from the sample mean, imply that _________ of the sample points are expected to fall between the upper and lower control limits.

Answers

Answer: 99.7%

Step-by-step explanation:

A control chart is used in the identification of the assigned causes of variation for a process. The control limits are refered to as the horizontal lines that are below and above the center line which are used in judging whether a particular process is out of control.

In this case, the control limits, which is calculated as three standard deviations from the sample mean, simply means that about 99.7% of the sample points will be expected to fall between upper and lower control limits.

1 US qt = 0.946352946 liters = 0.946352946 kg of pure water at temperature 4 °C.

US oz = 28.349523125 g

US fl oz = 29.5735295625 ml (milliliters) = 29.5735295625 g (grams) of pure water at temperature 4 °C.

US cup = 8 fl oz = 236.5882365 ml (milliliters) = 236.5882365 g (grams) of pure water at temperature 4 °C.

The US liquid quart equals to 0.946352946 liters.

Answer:

45 quarts is equal to exactly 93.8858 pounds.

Step-by-step explanation:

1 quart (qt) = 2.086351113 pound (lb).

Multiply 2.086351113 pounds by 45 to get your answer.

Answers

Answer:

Hi, there your answer is 9.5

Median=10

9 + 10 = 19

19 ÷ 2 = 9.5

Step-by-step explanation:

Sorry my bad I forgot to add and divide

Answer:

The median would be 9.5

Step-by-step explanation:

To find our answer we will first put them in numerical order:

3, 5, 7, 8, 8, 9, 10, 10, 10, 11, 12, 15

Now that we have the numbers in order, we will find the middle numbers.  Since the middle numbers are 9 and 10, we will add them both and divide them by 2.

9 + 10 = 19

19 ÷ 2 = 9.5

Therefore 9.5 is our answer!

Robbert wants to put lights around the edge of his yard.The yard if 40 feet long and 23 feet wide.How many yards of light does he need

Answers

Answer:

102.222 square yards of light.

Step-by-step explanation:

From the above question, the yard had the dimensions 40 feet long and 23 feet wide.

Hence, the yard is rectangular in shape.

We have to find the area of the yard.

The formula is given as:

Area = Length × Width

= 40 feet × 23 feet

= 920 square feet

Converting to yards

1 square foot = 0.111 square yard

920 square feet = x

Cross Multiply

x = 920 × 0.111 square yard

x = 102.222 square yards.

Therefore, Robbert would need 102.222 square yards of light.
