The two triangles are similar. What is the value for the ? ? Round to the nearest tenth if necessary.

L 28 35° K J ? R 42 35° P 33

Answers

Answer:

KJ = 22

Step-by-step explanation:

From the given diagram, since the figure are similar we can compare their sides.

So that,

[tex]\frac{JL}{PR}[/tex] = [tex]\frac{JK}{PQ}[/tex]

Let KJ be represented by x. But;

JL = 28, PR = 42 and PQ = 33

Thus,

[tex]\frac{28}{42}[/tex] = [tex]\frac{x}{33}[/tex]

x = [tex]\frac{28*33}{42}[/tex]

= [tex]\frac{924}{42}[/tex]

= 22

x = 22

The n,

KJ = 22

Ap calculus

Answer:

Step-by-step explanation:

For a lot of these summation problems it is worthwhile to learn to use a calculator or spreadsheet to do the arithmetic. Here, the ends of the intervals are 1 unit apart, so we only need to evaluate the function for integer values of x.

Almost any of these numerical integration methods involve some sort of weighted sum. For trapezoidal integration, the weights of all of the middle function values are 1. The weights of the first and last function values are 1/2. The weighted sum is multiplied by the interval width, which is 1 for this problem.

The area by trapezoidal integration is about 1.649 square units.

In the attached, we have shown the calculation both by computing the area of each trapezoid (f1 does that), and by creating the weighted sum of function values.

The frequency, or pitch, of a musical note varies inversely with the wavelength. The speed of sound, 340.2 meters per second, is the constant of variation.

An “A” note in octave 5, has a frequency of 880 Hertz. What is the wavelength of the sound made by the tuner in meters?

Answers

Answer:

The wave length = 0.387 meters

Step-by-step explanation:

Remark

An inverse relationship is one of the variables is in the denominator of a fraction and the other is given on the other side of the equal sign. It sounds more complicated than it is. Here's that long sentence broken down to 3 letters.

f = k/w

Formula

f = k/w

f is the frequency

k is the speed of sound

w is the wavelength

Givens

f = 880 Hz

k = 340.2 m/s

w = ?

Solution

f = k/w

880 = 340.2/ w Multiply both sides by w

880*w = w* 340.2 /w

880*w = 340.2 Divide by 880

w = 340.2/880

w = 0.387 m

For a party Gary buys cheese pizzas for $5 and pepperoni pizzas for $8 each. His bill comes to $75. Let x represent the number of cheese pizzas and y represent the number of pepperoni pizzas. Write an equation to represent the situation.

Answers

Answer:

The answer is the second answer from the image. Which is 5x-8y=$75

Step-by-step explanation:

It is that answer because it costs $5 for one cheese pizza and $8 for a pepperoni pizza, so the answer is 5x-8y=75

still confused?

Its that answer because the first one and the third one are the same, just both equations like in different ways like example 10+2 is 12 right? And 2 + 10 is still 12 so that means the second answer from the image is the answer.

Hope that helps.

Answer:

the answer for this question is the first choice.

Step-by-step explanation:

first, let's figure what number represents what. we know that cheese pizzas gary bought costed him $5 and pepperoni pizzas costed him $8. since x represents cheese pizzas and y represents pepperoni pizzas, 5x and 8y should be correct. this is also said in the problem which gives the correct addends. for the operation, it tells us the bill COMES to $75. since the pizzas are COMING to $75 in total, we know that this is addition.

12 divided by 1 1/5 = ?

IN lowest TERM

Answers

Answer:

12 divided by 1 1/5 = 60/11 in lowest term

I hope this helps you.

Step-by-step explanation:

Simplify the expression.

After converting mixed fraction into improper fractions,

12 divided by 1 1/5 = 10

Here we can write "12 divided by 1 1/5 " as,

12 ÷ [tex]1\frac{1}{5}[/tex]

Here [tex]1\frac{1}{5}[/tex] is in the form of a mixed fraction.

First of all we have to convert it into improper fraction,

Therefore multiplying 1 with denominator then add it to the numerator as,

[tex]1\frac{1}{5}[/tex] = (1x5 + 1)/5

= 6/5

Now we can write

12 ÷ [tex]1\frac{1}{5}[/tex] = 12 ÷ 6/5

= 12/(6/5)

= 12 x(5/6)

= (12/6)x5

= 2x5

= 10

Hence,

12 divided by 1 1/5 = 10.
