If l is Parallel to m, find the value of y

Mathematics
2 answers:
BARSIC [14]3 years ago
5 0

Step-by-step explanation:

1st

8x-59 + 2x-11 = 180

10x -70 = 180

10x = 180 + 70

10x = 250

x = 25

2nd

8x - 59 = 15y + 6

8(25) -59 = 15y + 6

200 -59 = 15y + 6

141 = 15y + 6

15y + 6 = 141

15y = 141 - 6

15y = 135

y = 135/15

y = 9

Answer:

y=9

Step-by-step explanation:

A line is equal to 180°.

8x-59+2x-11=180

10x-70=180

\frac{10x}{10} =\frac{250}{10}

x=25

8(25)-59=141°

2(25)-11=39°

(8x-59)° and (2x-11)° are complementary, so 141 + 39=180

(15y+6)°= (8x-59)°

15y+6= 141

15y=135

y=9

A company uses this formula to work out the cost, £A, of a taxi ride.
velikii [3]

Answer:

£b = £1.68

A = £44.68

Step-by-step explanation:

Given:

A = 5 + 1.9m + b

Where,

A = total cost

m = number of miles travelled

£b = charge for booking online

£5 = fixed charge

A. Harry

A = £29.48

m = 12 miles

£b = ?

A = 5 + 1.9m + b

29.48 = 5 + 1.9(12) + b

29.48 = 5 + 22.8 + b

29.48 = 27.8 + b

29.48 - 27.8 = b

b = 1.68

£b = £1.68

b) If Sue books online and travels 20 miles, what will be

A = 5 + 1.9m + b

= 5 + 1.9(20) + 1.68

= 5 + 38 + 1.68

= 44.68

A = £44.68

Use the Side-Splitter Theorem to find x, given that PQ||BC . The figure is not drawn to scale.
MrRa [10]

Answer: x=12


Step-by-step explanation:

1. Accoding to the Side-Splitter Theorem, if a line interesect two sides of the triangle and it is parallel to the third side, then the other two sides are divided by the line proportionally.

2. Then, you can form the following proportion:

\frac{PA}{BP}=\frac{QA}{CQ}

3. Substitute values and solve for x:

\frac{8}{x}=\frac{12}{18}\\18*8=12x\\x=12

How many litres of milk can be put in six hemispherical bowl each of diameter 35cm​
Lesechka [4]

Answer:

Approximately 67.348 litres can be put in six hemispherical bowl with a diameter of 35 centimetres.

Step-by-step explanation:

The volume of a hemisphere (V), measured in cubic centimetres, is obtained from this formula:

V = \frac{2\pi}{3}\cdot R^{3}

Where R is the radius of the hemisphere, measured in centimetres.

We know that radius is the half of the diameter (D), measured in centimetres, then:

R = 0.5\cdot D

(D = 35\,cm)

R = 0.5\cdot (35\,cm)

R = 17.5\,cm

Now, we get the volume of each hemispherical bowl:

V = \frac{2\pi}{3} \cdot (17.5\,cm)^{3}

V \approx 11224.649\,cm^{3}

The total volume of six hemispherical bowl is:

V_{T} = 6\cdot V

V_{T}= 6\cdot (11224.649\,cm^{3})

V_{T} = 67347.894\,cm^{3}

From Physics we know that 1 litre equals 1000 cubic centimetres. Then:

V_{T} = 67.348\,L

Approximately 67.348 litres can be put in six hemispherical bowl with a diameter of 35 centimetres.
