Answer:

x = 18

Step-by-step explanation:

When two parallel lines are intersected by a transversal, then same-side exterior angles are supplementary, meaning their angle measures add up 180 degrees. Applying this knowledge here, one can state that;

( 6x - 3 ) + 75 = 180

Simplify,

6x - 3 + 75 = 180

6x + 72 = 180

Inverse operations,

6x + 72 = 180

     -72      -72

6x = 108

/6     /6

x = 18

Answer:

5 < x < 13

Step-by-step explanation:

9+4 > x

4 + x > 9

Answer:

C. Tan 40 = 60/x

Step-by-step explanation:

Reference angle = 40°

Opposite side to reference angle = 60

Adjacent side = x

Apply trigonometric function TOA,

Tan 40 = Opp/Adj

Tan 40 = 60/x

Answer:

A. 3x+4y= 7.25

Step-by-step explanation:

Answer: A

Step-by-step explanation:

Answer:

Step-by-step explanation:

There isn't an exact answer for the first one since there are no like terms. But the steps to get 13x + 2= 41.

You'd have to find x.

In order to find x, you'll need to subtract 2 on both sides

13x + 2 = 41

      - 2 = - 2

You'll end up with:

13x = 41

Next step is to divide 13 on both sides.

13x/ 13 = 41/ 13

So, x = 41/ 13

Or simplified to 3.153

exponential growth

Step-by-step explanation:

b- 17/10 is > 1 so it is growth

Answer:

Right angle

Step-by-step explanation:

Given

Right angle and Acute angle

Required

Which is greater

An acute angle has its angles less than 90 degrees while a right angle has its angle to be exactly 90 degrees

Take for instance:

[tex]Acute\ Angle = 80[/tex]

[tex]Right\ Angle = 90[/tex]

By comparison: 90 > 80

So, right angle is greater.

Answer:

One solution

Step-by-step explanation:

Let's solve your equation step-by-step.

p+9=2p−3

Step 1: Subtract 2p from both sides.

p+9−2p=2p−3−2p

−p+9=−3

Step 2: Subtract 9 from both sides.

−p+9−9=−3−9

−p=−12

Step 3: Divide both sides by -1.

−p

−1

=

−12

Answer:

Option A: 300 square feet.

Step-by-step explanation:

In this question, all you do is divide! What is 450 / 1.5? 300. And don't forget to add your unit.

Answer:

675 sq ft

Step-by-step explanation:

If one gallon covers 450 sq ft, then 1.5 gallons covers 450 sq ft + 50% of 450.

So...

Divide 450 by 2

450 / 2 =

225

Then Add

450 + 225 =

675 sq ft

Answer:

66.3

Step-by-step explanation:

The tenths place is the first number to the right of the decimal

In this case, the 2

In order to round to this place, look at the number one place to its right. If the number is 4 or below, keep the same number 2. If the number is 5 or above, round the 2 to the next number, 3.

8 is above 5 so for this number, we will round the 2 to a 3

All the missing elements of the triangle by the Cosine rule are A = 40°, B = 45°, and C = 102°.

Given that,

Three sides on a triangle are,

a = 4

b = 5

c = 7

Used the formula of the Cosine rule which states that,

a² = b² + c² - 2bc cos A

b² = a² + c² - 2ac cos B

c² = a² + b² - 2ab cos C

Where, a, b, and c are three sides and A, B, and C are angles of a triangle.

Now, apply the Cosine rule to find the all angles of a given triangle,

a² = b² + c² - 2bc cos A

Substitute a = 4, b = 5 and c = 7,

4² = 5² + 7² - 2 × 5 × 7 cos A

16 = 25 + 49 - 70 cos A

70 cos A = 74 - 16

70 cos A = 58

Divide both sides by 58,

cos A = 58/70

cos A = 0.83

A = cos ⁻¹ (0.83)

A = 33.9°

Round to the whole number,

A = 40°

b² = a² + c² - 2ac cos B

Substitute a = 4, b = 5 and c = 7,

5² = 4² + 7² - 2 × 4 × 7 cos B

25 = 16 + 49 - 56 cos B

25 = 65 - 56 cos B

56 cos B = 65 - 25

56 cos B = 40

cos B = 40/56

cos B = 0.71

B = cos ⁻¹ (0.71)

B = 44.7°

Round to the whole number,

B = 45°

c² = a² + b² - 2ab cos C

Substitute a = 4, b = 5 and c = 7,

7² = 4² + 5² - 2 × 4 × 5 cos C

49 = 16 + 25 - 40 cos C

49 = 41 - 40 cos C

40 cos C = 41 - 49

40 cos C = - 8

cos C = - 8/40

cos C = - 1/5

cos C = - 0.2

C = cos ⁻¹ (0.2)

C = 101.5°

Round to the whole number,

C = 102°

Answer:

The porter charges Rs 300 at this rate.

Step-by-step explanation:

We solve this question by proportions, using rule of three.

75 Rs - 4 km - 50 kg

x Rs - 10 km - 80 kg

Relationship between the variables:

As the distance, or the weight increase, the rate will increase. This means that:

[tex]\frac{75}{x} = \frac{4*50}{10*80}[/tex]

[tex]\frac{75}{x} = \frac{200}{800}[/tex]

[tex]\frac{75}{x} = \frac{2}{8}[/tex]

[tex]x = \frac{75*8}{2} = 75*4 = 300[/tex]

The porter charges Rs 300 at this rate.
