Answer:

12-2=10 b=10

Step-by-step explanation:

Answer:

C)

Step-by-step explanation:

[tex]x = \frac{\sqrt{a}}{ \sqrt{b}} = \sqrt{\frac{a}{b}}\\\\[/tex]

Both sides take square

[tex]x^{2}= ( \sqrt{\frac{a}{b}})^{2}=\frac{a}{b}[/tex]

Answer:

The answer is b=0 or b=9.085603

Answer:

[tex]b^{2} \sqrt{30b}[/tex]

Step-by-step explanation:

143º I’m not sure

The bearing of town C from town A is 93.3 degree if the B is 7 km from A on a bearing of 037° C is 8 km from B on a bearing of 140°

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

If we extend the line NA and NB

As we can see, line NA and NB are parallel and cut by transversal AB

The angle NBA and BAN' will be equal.

Angle BAN' = 180 - 37 = 143 degree = angle NBA

Angle CBA = 360 - 140 - 143

Angle CBA = 77 degree

Now, applying cos law:

b² = a² + c² - 2ac[cos B]

b² = (8)² + (7)² - 2(8 x 7 x cos77)

b = 9.37 km

To find the measure of the angle A applying sin law:

(sinA)/a = (sinB)/b

sinA = (axsinB)/b

sinA = (8xsin77)/9.37

A = 56.3⁰

Bearing of town C from town A:

α = A + 37⁰

α = 56.3⁰ + 37⁰

α = 93.3⁰

Thus, the bearing of town C from town A is 93.3 degree if the B is 7 km from A on a bearing of 037° C is 8 km from B on a bearing of 140°

I did the test and got it right.

Answer:

I believe it 13

Step-by-step explanation:

150+50= 200 then 100= two months so i added up till i got 13 weeks

Answer:

70 degrees

Step-by-step explanation:

If cosm<A = 342/1000, we are to find the value of a

Take arccos of both sides

cosm<A = 342/1000

cosm<A = .342

arccos(cosm<A) = arccos(0.342)

m<A = arccos(0.342)

m<A = 70 degrees

Hence the measure of m<A is 70 degrees

Answer:cost of each donut =$4

and cost of each cup of hot chocolate =$2

Step-by-step explanation:

Step 1

Let donuts be represented as d

and cups of hot chocolate be rep as c so that

5 donuts and 2 cups of hot Chocolate costing 24$ will be expressed as

5 d+ 2 c= 24

And 2 donuts and 3 cups of hot chocolate costing  14$ will be expressed as

2d +3 c= 14

Step 2

Using elimination method,Multiply equation 1 by 3 and equation 2 by 2

15d+ 6c= 72----equation 3

4d+ 6c= 28-----equation 4

Subtracting equation 4 from equation 3 gives us

11 d=44

d= 44/11

d= 4

To find c, using equation 1

5 d+ 2 c= 24

5 x 4+ 2c=24

20+2c=24

2c=24-20

2c=4

c=4/2 =2

cost of each donut =$4

and cost of each cup of hot chocolate =$2

Answer:

Step-by-step explanation:

1, 2. The area of each triangle is given by the formula ...

  A = (1/2)bh . . . . . for base b and height h

The area of the given triangle is ...

  A = (1/2)(7 in)(15 in) = 105/2 in² = 52.5 in²

Triangles 1 and 2 have the same dimensions, so have the same area.

  Figure 1 area: 52.5 in²

  Figure 2 area: 52.5 in²

__

3. The area of the semicircle is given by the formula ...

  A = (1/2)πr² . . . . for a semicircle of radius r

This semicircle has a radius of 7 in, so an area of ...

  A = (1/2)(3.1416)(7 in)² ≈ 76.97 in²

  Figure 3 area: 76.97 in²

__

The total area is the sum of these:

  52.5 in² + 52.5 in² +76.97 in² = 181.97 in²

  Composite Figure area: 181.97 in²

_____

Comment on decimal digits

We cannot tell your rounding requirements. Here, we have rounded to the nearest hundredth. If you use the value 3.14 for pi, then your areas for the semicircle and composite figure will end in .93, not .97.

Answer: m and n

8(m+n)= 8m + 8n

Answer:

The answer would be 180 meters.

Step-by-step explanation:

We are told the runner runs at 9 m/s for 20 seconds.

Since they run 9 meters per second, all we have to do is multiply 9 by 20, which will give us 180 meters.

9 x 20 = 180

Actually Welcome to the Concept of the Similar Triangles.

Since here we can see that, similar triangles different by size of the side by 0.5 ration,

hence,the value of x = 0.5 times of MN

hence, x = 5/2

so the mixed fraction representation is given as,

[tex]2 \times \frac{1}{2} [/tex]

mixed fraction ration is 2(1/2)

===> hence option is B.)

Methods to Find LCM of 4, 9 and 12

Least Common Multiple of 4, 9 and 12 is the smallest number, which is exactly divisible by all of them without any remainder.

Multiples of 4 = 4, 8, 12, 16, 20, 24, 28, 32, 36.

Multiples of 9 = 9, 18, 27, 36.

Multiples of 12 = 12, 24, 36.
