Answers

Answer:

Step-by-step explanation:

As we know that the sum of interior angles of triangle is 180⁰.

So, according to the question :

[tex]\begin{gathered} \qquad{\longrightarrow{\sf{Sum \: of \: all \: angles = {180}^{\circ}}}}\\\\ \qquad{\longrightarrow{\sf{{74}^{\circ} + {52}^{\circ} + 18u = {180}^{\circ}}}}\\\\\qquad{\longrightarrow{\sf{{126}^{\circ} + 18u = {180}^{\circ}}}}\\\\\qquad{\longrightarrow{\sf{18u = {180}^{\circ} - {126}^{\circ}}}}\\\\\qquad{\longrightarrow{\sf{18u = {54}^{\circ}}}}\\\\\qquad{\longrightarrow{\sf{u = \dfrac{54}{8}}}}\\\\\qquad{\longrightarrow{\sf{u = {3}^{\circ}}}}\\\\ \qquad\star{\underline{\boxed{\frak{\pink{u = {3}^{\circ}}}}}}\end{gathered}[/tex]

Hence, the value of u is 3.

The perimeter of a rectangle is 76. The length is 20 more than the width. Find the width and length.

Answers

Answer: The width is 9 units and the length is 20 units

Step-by-step explanation:

Perimeter is length + length + width + width, (P = 2l + 2w)

76 = 2(w+20) + 2w

76 = 2w + 40 + 2w

76 = 4w + 40

Subtract 40 on both sides

36 = 4w

Divide both sides by 4

9 = w

That means the length is 29 and the width is 9. To check out work, add 29+29+9+9 to get 76. Our answer is correct.

Three strong cables are used to brace a 20m tall pole against movement due to the wind. Each cable is attached so that the angle of elevation to the top of the pole is 55 degrees. Find the total length of the cables.

Answers

Answer:

  73.25 m

Step-by-step explanation:

In the right triangle formed by the pole, the ground, and the cable, the pole is the side opposite the angle of elevation, and the cable is the hypotenuse of the triangle. The relevant trig relation is ...

  Sin = Opposite/Hypotenuse

Solving for the Hypotenuse, we find ...

  Hypotenuse = Opposite/Sin

  cable length = (20 m)/sin(55°) ≈ 24.4155 m

The total length of the 3 cables is ...

  3 × (24.4155 m) ≈ 73.25 m

The total length of the cables is about 73.25 meters.

__

In the attached, we computed the length of a single cable for a pole 3 times as high. That will be the same length as the total we seek here.

Solve the equation q+5/9=5/6 q=?

Answers

Answer:

q = 5/18

Step-by-step explanation:

q + 5/9 = 5/6

Subtract 5/9 from each side

q + 5/9 - 5/9 = 5/6 - 5/9

q = 5/6 - 5/9

Get a common denominator of 18

q = 5/6 *3/3 - 5/9 *2/2

q = 15/18 - 10/18

q = 5/18

⭐ The question asks for the area of the restaurant which is in shape of circle.

⭐ The standard formula for calculating the area of circle is given by (A = πr²)

(π = 3.142 or 22/7), (r = 6miles) and we have to find the area (A) = ?

Given data:

Area (A) = ?

Radius of circle (r) = 6 miles

Solution:

[tex]:\implies\tt{Area = \pi {r}^{2} }[/tex]

[tex]:\implies\tt{Area = 3.142 \times {6}^{2} }[/tex]

[tex]:\implies\tt{Area = 3.142 \times 6 \times 6}[/tex]

[tex]:\implies\tt{Area = 18.852 \times 6}[/tex]

[tex]:\implies\tt{Area = 113.112 {miles}^{2} }[/tex]

[tex]:\implies\tt{Area = 114 {miles}^{2} }[/tex]

Thus, the area of food restaurant is 113.112 miles² or 114 miles ²

The school store sells pencils and erasers.
• For 3 pencils and 2 erasers, the cost is $0.76.
• For 2 pencils and 4 erasers, the cost is $1.04.
How much more does 1 eraser cost than 1 pencil?

Answers

Answer:

$0.18

Step-by-step explanation:

we need to set up two simultaneous equations

using variables, pencils = p and erasers = e

3 pencils and 2 erasers, the cost is $0.76

3p + 2e = $0.76

2 pencils and 4 erasers, the cost is $1.04.

2p + 4e = $1.04

we now have

3p + 2e = $0.76

2p + 4e = $1.04

to make the number of erasers the same, multiply the first equation by 2 to give 4e

2(3p + 2e = $0.76)

6p + 4e = $1.52

now we have the same number of erasers for both equations

6p + 4e = $1.52

2p + 4e = $1.04

subtract across: 6p - 2p = 4p, 4e - 4e = 0, $1.52 - $1.04 = $0.48

we are left with 4p = $0.48

divide both sides by 4

p = $0.12

1 pencil = $0.12

go back to the start of both equations and use one of them to find 1 eraser. I'll use 3p + 2e = $0.76

input $0.12 in p

3($0.12) + 2e = $0.76

$0.36 + 2e = $0.76

subtract $0.36 on both sides

2e = $0.76 - $0.36

2e = $0.40

divide 2 on both sides

e = $0.20

1 eraser = $0.20

How much more does 1 eraser cost than 1 pencil?

we now know 1 pencil = $0.12 and 1 eraser = $0.20

find the difference between them

$0.20 - $0.12 = $0.18

final answer= $0.18

b) the formula is a(first term)-1(n-1) so the nth term is 118-(n-1) which is 118-n+1 and its simplest form is 119-n so the 50th term is gonna be like this: 119-50=69

The answer to this question is very simple 120.

You can even do it systematically.

Take a=114, d = a2 - a1 = 116 - 114 =2

So now you get, a1= 114, d = 2

Now you want the 4th term so,

a4 = a + (n-1)d

a4 = 114 + 3 (2)

a4 = 114 +6 = 120
