Answer:

$130

Step-by-step explanation:

Given data

Customer bill= $125

Charge= 4%

let us find 4% of $125

=4/100*125

=0.04*125

=$5

Hence the  bill including the local fee is

=125+5

=$130

Answer:

60.1°

Step-by-step explanation:

We solve the above question using the Trigonometric function of Sine

sin x = Opposite/Hypotenuse

x = Angle of Depression

Opposite = 15ft

Hypotenuse = 17.3ft

sin x = 15ft/17.3ft

x = arc sin (15ft/17.3ft)

x = arcsin(0.8670520231213873)

60.117851927°

Approximately Angle of depression = 60.1°

Answer:

Answer:

x = 50°

y = 50°

x = 50°

y = 50°

Answer:

Kamal 6,000

Kamala 9,000

Krishna 15,000

Step-by-step explanation:

2 + 3 + 5 = 10 units

30,000/10 = 3,000 per unit

2 units = 2 x 3000 = 6,000

3 units = 3 x 3000 = 9,000

5 units = 5 x 3000 = 15,000

Answer:

x≥−3

Step-by-step explanation:

−4x−10≤2

Step 1: Add 10 to both sides.

−4x−10+10≤2+10

−4x≤12

Step 2: Divide both sides by -4.

−4x−4≤12

Answer:

-62

Step-by-step explanation:

180-w+49(angles  on  a straight line=180)

angles on a triangle=180

Hence,

         180-w+49+w+17+w-4=180

collect the like terms

180+49+17-4+w+w-w=180

242+w=180

Take 180 to the other side and also w

242-180=-w

62=-w    same as w=-62

Using the information displayed on the two-way table, the true statement ls "About 1/3 of his classmates live near a pool and do not own a bike".

From the distribution table :

There are many of his classmates who own a bike and also live near a pool and vice versa.

The number of his classmates who live near a pool and do not own a bike is 10

Total number of class mates = 30

Fraction who do live near a pool and do not own a bike can be calculated thus :

Hence, about 1/3 of the students live near a pool and do not own a bike.

Answer:36cm

Step-by-step explanation:The area of a circle is pi times the radius squared (A = π r²

a) Diameter is 12cm

; (b) radius is 6cm

; and (c) area is 36πcm2.

Explanation:If r is the radius of a circle, then its circumference is 2πr

and area is πr2.

As circumference is given to be 12π, we have 2πr=12π

or r=12π2π=6cm.

As such radius is 6cm

and diameter being double of radius, diameter is 2×6=12cm.

and area is π×62=36 cm2
