Answer:

I think may be it is Option 2 (AB)

∡ NKM + ∡KNM + ∡ NMK = 180° Because Angles in a triangle ΔNKM sum to 180°

∡ NKM + 90° + 60° = 180°

∡ NKM = 30°

∡ NKM = ∡JKN = ∡ MKL = 30° because ΔJKM∼ΔNKM∼ΔMKL

Finally:

∡ JKL = ∡ NKM + ∡JKN + ∡ MKL

∡ JKL =  30° +  30° +  30°

∡ JKL = 90°

With the help of properties of triangle ∠JKL = 90 degrees.

To prove:

∠JKL = 90 degrees.

Here,

Angle sum property of triangle:

In any triangle sum of angles is 180 degrees.

So,

In ΔNKM

∡ NKM + ∡KNM + ∡ NMK = 180°

∡ NKM + 90° + 60° = 180°

∡ NKM = 30°

Now,

ΔJKM∼ΔNKM∼ΔMKL (By AAA)

Thus,

∡ NKM = ∡JKN = ∡ MKL = 30°

Next,

∡ JKL = ∡ NKM + ∡JKN + ∡ MKL

∡ JKL =  30° +  30° +  30°

∡ JKL = 90°

Hence proved.

We need to know about ratio to solve the problem. The ratio of 350[tex]cm^{3}[/tex] to 1 litre as a ratio in its lowest terms is 7:20.

Ratio is the measure of how many times one number contains another in it. We can find the ratio of one quantity to another by dividing one by the other by cancelling out the common factors between the two. We have to find the ratio of 350[tex]cm^{3}[/tex] to 1 litre in its lowest terms. The lowest terms for both the quantities is [tex]cm^{3}[/tex]. We know that 1 litre =1000[tex]cm^{3}[/tex], we will convert the 1 litre to 1000[tex]cm^{3}[/tex] for calculating the ratio.

The ratio of 350 [tex]cm^{3}[/tex] to 1 litre =350/1000=35/100=7/20= 7:20

Therefore we found the ratio of 350 [tex]cm^{3}[/tex] to 1 litre in its lowest terms to be 7:20 by using the concept of ratio.

Step-by-step explanation:

Answer:

(b + 3)/2

Step-by-step explanation:

Based on the perimeter value, the width of the rectangle is 1.75 inches

The perimeter of a shape is the sum of the side lengths of the shape

For all regular quadrilaterals, you add up the side lengths to determine the perimeter

The given parameters about the rectangle are

Perimeter = 17

Length = Width + 5

Rewrite the above equations as

l = w +  5

p = 17

The perimeter of a rectangle is

p = 2 x (l + w)

Substitute p = 17 in the above equation

So, we have

2 x (l + w) = 17

Substitute l = w+ 5 in the above equation

So, we have

2 x (w + 5 + w) = 17

Evaluate the like terms in the above equation

So, we have

2 x (2w + 5) = 17

Open the bracket in the above equation

So, we have

4w + 10 = 17

Evaluate the like terms in the above equation

So, we have

4w = 7

Divide both sides of the above equation by 4

So, we have

w = 1.75

Hence, the width of the rectangle is 1.75 inches

Answer:

x=y-44 and x+y=410

Step-by-step explanation:

So, you want to use the equations x=y-44 and  x+y=410 when x is Ann's score and y is Ruth's score. This is because x (Ann's score) is Ruth's score (y) but 44 less, so you subtract y-44 to get x. Then x+y would also have to equal 410 so that's the other equation. Graphing the 2 equations gets you to the point  (183,227) in which Ann's score is 183 points and Ruth's score is 227 points.

Answer:

An equation to  represent the situation would be:

Step-by-step explanation:

Given that the water supply is losing 4 gallons of water every second.

It means the rate of change = 4 gallons per second

So the equation becomes

1024 = 4(15) + b

comparing with the slope-intercept form of the equation of a line

[tex]y = mx+b[/tex]

where m is the slope (rate of change) and b is the y-intercept

so

[tex]1024 = 4(15) + b[/tex]

[tex]1024 = 60 + b[/tex]

[tex]1024 - 60 = b[/tex]

[tex]b = 964[/tex]

So, the value of y-intercept i.e b=964

Thus, the equation will be

[tex]y = mx+b[/tex]

substituting the value rate of change i.e m = 4 and b=964

[tex]y = 4x + 964[/tex]

Therefore, an equation to  represent the situation would be:

Step-by-step explanation:

Answer:

The Distance from the center ( B ) of the smaller circle to its edge is the radius of the circle therefore  length BD = length AB

From the given diagram

The center of the bigger circle is at C while

The center of the smaller circle is at point B .

The smaller circle cuts through the bigger circle creating two segments BD and AB which starts from the middle of the smaller circle to the intersecting edges of the circles.

Hence the length of segment BD = length of segment AB because they both start from point B .

Answer:

C = 99 + 49m

x = $99

y = $49

Step-by-step explanation:

Let

x = one time joining fee

y = monthly payment

Your friend:

1 year = 12 months

x + 12y = $687

You:

x + 18y = $981

x + 12y = 687 (1)

x + 18y = 981 (2)

Subtract (1) from (2)

18y - 12y = 981 - 687

6y = 294

Divide both sides by 6

y = 294 /6

= 49

x = $49

Substitute y = 49 into

x + 12y = 687

x + 12(49) = 687

x + 588 = 687

x = 687 - 588

= 99

x = $99

C = 99 + 49m

Where,

C = total charges

m = number of months

99 = a one time joining fee

49 = charges per month

Answer:

1/25

Step-by-step explanation:

We can see that in this pattern, the denominator and the numerator of the next fraction cancel out; they're the same.

(1/2) x (2/3) x (3/4) = 1/4 (do you see it?)

The only things that do not cancel out are the numerator of the first fraction and the denominator of the last. So, in the end, the answer will be 1/25.

Answer:

Step-by-step explanation:

To solve this, we need to use the Pythagorean theorem to solve this.

The way to solve is by solving for AD by using triangle CAD and then using that result to solve for BD.

3.4² + b² = 6.5²

11.56 + b² = 42.25

42.25 - 11.56 = b²

b = √30.69

b = 5.53985559 or about 5.5

4.9² + b² = 5.5²

24.01 + b² = 30.69

30.69 - 24.01 = 6.68

b = √6.68

b = 2.58456959666 or about 2.6

3.4 + 4.5 = 7.9

6.5² + 4.9² = 7.9²

66.26 doesn't equal 62.41
