For a right triangle, the side that is opposite of the right angle is called the hypotenuse. This side will always be the longest side of the right triangle. The other two (shorter) sides are called legs.

Answer:

m<A: 62

m<B: 54

Step-by-step explanation:

180 - 116 = 64

3x - 13 + 2x + 4 + 64 = 180

5x + 55 = 180

5x = 180 - 55

5x = 125

x = 25

m<A:

3x - 13

3(25) - 13

Answer:

184.85 square mm

Step-by-step explanation:

The area of a sector of a circle is , where r is the radius and  is the angle in radians subtended by the arc at the centre of the circle.

Since, diameter = 40.6 mm

So, radius(r)=20.3 mm and  = radians

So, area of sector=

Answer:

AD = 230

Step-by-step explanation:

AD = 30x - 10

MN = 31x + 1

BC = 30x + 28

To find the length of AD, we need to generate an equation that will enable us to find the value of x.

Thus,

MN = ½(AD + BC) => Trapezoid Midsegment Theorem

Plug in the values

31x + 1 = ½(30x - 10 + 30x + 28)

(31x + 1) × 2 = 30x - 10 + 30x + 28

62x + 2 = 30x - 10 + 30x + 28

Add like terms

62x + 2 = 60x + 18

62x - 60x = -2 + 18

2x = 16

x = 16/2

x = 8

✅AD = 30x - 10

Plug in the value of x

AD = 30(8) - 10 = 230

Answer:

4. y = 1/2x + 3/2

Step-by-step explanation:

First, we need to change the line that's parallel into slope-intercept form.

-2x + 4y = 8

4y = 2x + 8

y = 1/2x + 2

If it's parallel, then it remains the same. So our slope is 1/2.

To find the y-intercept, you need to plug the coordinates into the equation.

y = 1/2x + b

-1 = 1/2(-5) + b

-1 = -5/2 + b

3/2 = b

y = 1/2x + 3/2

Hey! It's me again! You told me to answer this, so I will deliver ☺

Answer:

15/21

Step-by-step Explanation:

Because 1/3 and 2/7 do not have the same denominator, we will have to multiply them to get one that they'll both share.

In this case, you multiply both denominators, 3 and 7, to get 21.

We do the same with the numerators, but in a different way.

We're gonna multiply the numerators by the OTHER fractions' denominators this time. So, we do this:

1 x 7 = 7

2 x 3 = 6

We end up getting these fractions:

7/21

6/21

And now, we just subtract 6 from 21, to get 15.

And you get 15/21.

I hope I helped you, and a "Brainliest" is always appreciated! ☺

Answer:

sqrt(8) or 2.828

Step-by-step explanation:

You use the distance formula which is sqrt((x2-x1)^2+(y2-y1)^2) where x2 can be either x value

Answer:

sqrt(8) units

Step-by-step explanation:

Use the formula d=sqrt((x2-x1)^2 + (y2-y1)^2). d=distance, and (x1, y1) and (x2, y2) are the points.

d=sqrt((4-2)^2 + (1-3)^2)

 =sqrt(2^2 + (-2)^2)

 =sqrt(4+4)

 =sqrt(8)

A and B are sqrt(8) units apart.

Answer:

f(x)=(x+2)^2+37

Step-by-step explanation:

Got it right on Khan :)

The quadratic function f(x) = x² + 4x + 41 is converted into square form is f(x) = (x + 2)² + 37.

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.

The quadratic function is given below.

f(x) = x² + 4x + 41.

The quadratic function is converted into square form by adding and subtracting the square of the half of the coefficient of x.

f(x) = x² + 4x + 41

Transform into square form. Then the quadratic function will be

f(x) = (x² + 4x + 4) + 41 – 4

f(x) = (x + 2)² + 37

The quadratic function f(x) = x² + 4x + 41 is converted into square form is f(x) = (x + 2)² + 37.

388,000,000

Step-by-step explanation:

So as we have 322 million

we want to take 0.81% of it and add to the total each year so

322,000,000*0.81%=2,608,200

322,000,000+2,608,200=324,608,200

and now do that for 22 more years so

We get 387,649,305.98 as our population

387,649,305.98 -------> 388,000,000

Answer:

499/999

Step-by-step explanation:

The decimal number written is:

0.499...

Such that these 3 decimals are repeated as:

0.499499499...

Let's define this number as k

k = 0.499...

Let's multiply this number by 1000 (the same number of zeros as important decimals after the decimal point)

we get:

1000*k = (1000)*(0.499...) = 499.499...

Now we can subtract the original number k, so we get:

1000*k - k = 499.499... - 0.499...

In this way, we remove the part after the decimal point:

1000*k - k = 499.499... - 0.499...

(1000 - 1)*k = 499

999*k = 499

Now we can divide both sides by 999

(999*k)/999 = 499/999

k = 499/999

The fraction notation of our number is 499/999 (and this is the simplest form)

Answer:

475 children

Step-by-step explanation:

A restaurant has many vistors over the weekend.4/9 of the visitors are adults. If there were 380 adults, how many visitors were children? Answer

Step 1

We find the total number of visitors the restaurant had over the weekend. This is calculated as:

Let the total number of visitors = x

4/9 × Total number of visitors = 380 Adults

4/9 × x = 380

4x/9 = 380

Cross Multiply

4x = 9 × 380

x = 9 × 380/4

x = 855 visitors.

Step 2

The number of visitors that were children is calculated as:

Total number of visitors - Number of Adults

= 855 visitors - 380 Adults

= 475 children

Answer:

r = 1/2

Step-by-step explanation:

sphere volume = 4/3πr³

4/3πr³ = 1/6π

divide both sides of the equation by π:

4/3r³ = 1/6

multiply both sides by 6:

24/3r³ = 1

reduce:

8r³ = 1

divide both sides by 8:

r³ = 1/8

r = 1/2
