x = 56.5 and rounded to the nearest tenth is still gonna be 56.5 but to the nearest TENS is 60 (Please give brainliest!!)

Step-by-step explanation:

His is a right triangle so you can use SOH CAH TOA :

Sine = opposite/ hypotenuse

Cosine= adjacent/ hypotenuse

Tangent = opposite/ adjacent

here you have the hypotenuse and are looking to solve for the adjacent side to angle measure 28

so you can set this up like this: cos(28)= x/64

now multiply both sides by 64 and you'll get x = 56.5 just make sure your calculator is in degrees not radians

Answer:

Step-by-step explanation:

triangles CDB and ADB are equal so we know that CD=AD and can write this equation:

3x+5 = 5x-7

subtract '3x' from each side:

5 = 2x-7

add 7 to each side:

12 = 2x

12/2 = x

1. 43+(-56) - 78

43 - 56 - 78 = -91

2. -78 - 65 = -143

3. -19 - 4 = -23

4. -16 + 9 = -7

5. 71 + (-18)

71 - 18 = 53

Hope this helps!

Answer:

Step-by-step explanation:

43+(-56)minus 78= negative 91

43+-56= - 13    13-78= negative 91

-78 subtract 65=143 because when your in negatives it is opposite so when you subtract it is addition so what is -30 add 50=20. So what is -78 subtract 65=143

-19 subtract 4 =-23 because like I said in negatives it's opposite.

-16+9=7.

And last 71 + -18=53 because it is subtracting 18 since it is negatives.

Hope it helps :)

Answer:

Equation 1:  8x + 10y = 123.4

Equation 2:  5x + 9y = 97.2

cost of a burrito = $7.30

cost of a sandwich = $6.30

Step-by-step explanation:

Let x = cost of a sandwich

Let y = cost of a burrito

Equation 1:  8x + 10y = 123.4

Equation 2:  5x + 9y = 97.2

Rewrite equation 1 to make y the subject, then substitute into equation 2 and solve for x:

8x + 10y = 123.4

⇒ 10y = 123.4 - 8x

⇒ y = 12.34 - 0.8x

5x + 9(12.34 - 0.8x) = 97.2

⇒ 5x + 111.06 - 7.2x = 97.2

⇒ 13.86 = 2.2x

⇒ x = 6.3

So cost of a sandwich = $6.30

Substituting x = 6.3 into equation 2 and solving for y:

5(6.3) + 9y = 97.2

⇒ 31.5 + 9y = 97.2

⇒ 9y = 65.7

⇒ y = 7.3

So cost of a burrito = $7.30

Answer:

8x + 10y = 123.40

5x + 9y = 97.20

OR

40x + 50y = 617

-40x - 72y = -777.6

x = $6.30

y = $7.30

Step-by-step explanation:

we can write this system of equations:

8x + 10y = 123.40

5x + 9y = 97.20

using the 'elimination method', we can multiply the first equation by 5 and the second equation by -8 to get:

5(8x + 10y) = 123.4(5)

40x + 50y = 617

-8(5x + 9y) = 97.2(-8)

-40x - 72y = -777.6

now we can add the new equations and solve for 'y':

40x + 50y = 617

-40x - 72y = -777.6

-22y = -160.6

y = 7.30

now we can substitute 7.3 for 'y' so we can solve for 'x':

8x + 10(7.3) = 123.4

8x + 73 = 123.4

8x = 50.4

x = 6.30

Answer:

Measure of each angle is 108 and 72 degrees.

Step-by-step explanation:

Let's the angle  be "n"

Supplementary angle = 180 °

n- (180-x) = 36

n - 180 + n = 36

Combine like terms

n - 180 + n = 36

2n - 180 = 36

Add 180 to both sides of the equation

2n - 180+180 = 36+180

Simplify

2n = 216

Divide both sides of the equation by the same term

2n/2 = 216/2

Simplify

n = 108

2n = 216  

Measure of each angle

1st = 108

2nd = 180-108 = 72

Answer:

An angle measures 36° more than the measure of its supplementary angle. What is the measure of each angle?

Step-by-step explanation:

Let's the angle  be "n"

Supplementary angle = 180 °

n- (180-x) = 36

n - 180 + n = 36

Combine like terms

n - 180 + n = 36

2n - 180 = 36

Add 180 to both sides of the equation

2n - 180+180 = 36+180

Simplify

2n = 216

Divide both sides of the equation by the same term

2n/2 = 216/2

Simplify

n = 108

2n = 216  

Measure of each angle

1st = 108

2nd = 180-108 = 72

All the square root term are equal then they can be added. Then the length of piping is needed in all is 98√6.

It is the measure of distance between the two points is called a length. It is a scalar quantity.

A builder needs three pipes of different lengths.

The pipes are 6√96 feet long, 12√150 feet long, and 2√294 feet long.

The length of pipes can be written as

[tex]6\sqrt{96} = 6 \sqrt{2*2*2*2*2*3} = 24\sqrt6[/tex]

[tex]12\sqrt{150} = 12 \sqrt{5*5*6} = 60\sqrt6[/tex]

[tex]2\sqrt{294} = 2 \sqrt{6*7*7} = 14\sqrt6[/tex]

Since all the square root term are equal then they can be added.

[tex]24 \sqrt{6} + 60 \sqrt{6} + 14\sqrt{6}\\\\98\sqrt{6}[/tex]

Thus, the length of piping is needed in all is 98√6.

9. log(2)=a, log(3)=b, then log(36)=______

log(36) = log(6*6) = log(6) + log(6)

log(36)= log(6) + log(6)

log(36) = log(3*2) + log(3*2)

log(36) = (log(3) + log(2)) + (log(3) + log(2))

log(36) = (a + b) + (b + a)

log(36) = a + b + b + a

log(36) = 2a + 2b

Answer:

x = 2 , y = -3

Step-by-step explanation:

by elimination method

+5y in equation 1 cancel -5y in equation 2

2x - 8x = -11 - 1

-6x = -12

divide both sides by - 6

- 6x/ -6 = -12/-6

x = 2

substitute x = 2 into equation ii

- 8 (2) - 5y = - 1

- 16 - 5y = - 1

collect like terms

- 5y = -1 + 16

- 5y = 15

divide both sides by -5y

-5y/-5y = 15/-5y

y = - 3

Answer:

  3.09 miles

Step-by-step explanation:

Given one distance and two angles, we will need to use the Law of Sines. For this, we need to know the internal angles of the triangle formed by the various bearing lines.

The angle between the bearings of A and B from the transmitter will be the difference of the reverse of the given bearings.

  A from T = 39.3° +180° = 219.3°

  B from T = 313.9° -180° = 133.9°

Then the angle at T between receivers is ...

  219.3° -133.9° = 85.4°

The angle between A and T as measured at B will be ...

  313.9° -270° = 43.9°

These angles and length AB can be used with the Law of Sines to find AT:

  AT/sin(B) = AB/sin(T)

  AT = AB(sin(B)/sin(T)) = (4.44 mi)·sin(43.9°)/sin(85.4°)

  AT ≈ 3.09 mi

The distance of the transmitter from A is about 3.09 miles.
