B.
It usually doubles as an MP3 player and keeps people motivated.
C.
They help people reach their goals by counting the number of steps taken.
D.
They measure the number of lifts done during each exercise performed.

Answer: 3.33% (choice B)

===================================================

Work Shown:

A = true value = 60

B = estimated or measured value = 62

C = percent error

C = ( |A-B|/A ) * 100%

C = ( |60-62|/60 ) * 100%

C = (2/60)*100%

C = 0.0333*100%

C = 3.33%

The result is approximate.

Answer:

C   y = 2sin(1/3) x

Step-by-step explanation:

It's a sin function since y = 0 at x = 0

The amplitude is 2

There are 2 cycles in 12π

so the period is 6π

The x coefficent is then 2π/6π  = 1/3

Answer:

The value of x in the triangle is 17.51

Option C is the correct answer.

We have,

From the figure,

We can use the tangent function.

This means,

Tan = perpendicular / Base

i.e

tan 35 = x / 25

0.700 = x / 25

x = 0.700 x 25

x = 17.5

Thus,

The value of x in the triangle is 17.51.

x= 2, y= 5

Step-by-step explanation:

5x -4y= -10 -----(1)

3x +2y= 16 -----(2)

(2) ×2:

6x +4y= 32 -----(3)

(1) +(3):

5x -4y +6x +4y= -10 +32

11x= 22

x= 22 ÷11 (÷11 on both sides)

x= 2

Substitute x= 2 into (2):

3(2) +2y= 16

6 +2y= 16

2y= 16 -6

2y= 10

y= 10 ÷2

Answer:

A = [12 + 9(pi)] yd^2 = 40.3 yd^2

Step-by-step explanation:

A = area of triangle + area of semicircle

A = bh/2 + (pi)r^2

A = (6 yd)(4 yd)/2 + (pi)(3 yd)^2

A = 12 yd^2 + 9(pi) yd^2

A = [12 + 9(pi)] yd^2 = 40.3 yd^2

Answer:

ans : option 2nd

Step-by-step explanation:

total angle substand perimeter of circle so,

so solve by using unitary methods

The value of x is 84 degrees.

The tangent line to a circle  at a given point is the straight line that just touches the circle at the point.

A tangent to a circle is perpendicular to the radius at the point of tangency.

According to the question

we have to find the value of x.

Let us assume that a circle have a center at O. And Mark the end of the given chord P and Q.

Connect OP and OQ.

here,

OP = OQ

⇒∠OQP = ∠QPO

Now in triangle POQ, we have

⇒∠QOP + 2∠ OPQ = 180

⇒168 +2∠OPQ =180

⇒2∠OPQ = 12

⇒∠OPQ =6 degrees.

As we know that, tangent to a circle is perpendicular to the radius at the point of tangency.

⇒ x + ∠QOP = 90

⇒ x + 6 = 90

⇒ x = 90-6 = 84 degrees.

Hence, value of x is 84 degrees.

Answer:

I don't know for sure, but I'm pretty sure its 1,640.

Step-by-step explanation:

80% of 8,200 is 6560, and then do 8,200- 6,560, you get 1,640.

According to question, The price at which it was sold is equal to :

The car was sold at $ 6560

Now, loss is equal to :

Answer:

The company needs to sell either 30 or 40 items.

Step-by-step explanation:

We are given that the cost for selling x items given by the function:

[tex]C(x)=40x+180[/tex]

And the revenue for selling x items is given by:

[tex]R(x)=68x-0.4x^2[/tex]

The profit function is the cost function subtracted from the revenue function:

[tex]P(x)=R(x)-C(x)[/tex]

Substitute and simplify:

[tex]\displaystyle \begin{aligned} P(x)&=(68x-0.4x^2)-(40x+180)\\&=68x-0.4x^2-40x-180\\&=-0.4x^2+28x-180\end{aligned}[/tex]

To find how many items must be sold in order to obtain a weekly profit of $300, we can let P equal 300 and solve for x. So:

[tex]300=-0.4x^2+28x-180[/tex]

Solve for x. Subtract 300 from both sides:

[tex]-0.4x^2+28x-480=0[/tex]

We can divide both sides by -0.4:

[tex]x^2-70x+1200=0[/tex]

Factor:

[tex](x-40)(x-30)=0[/tex]

Zero Product Property:

[tex]x-40=0\text{ or } x-30=0[/tex]

Solve for each case:

[tex]x=40\text{ or } x=30[/tex]

So, in order to obtain a weekly profit of $300, the company need to sell either 30 or 40 items.

Three friends, Cleopatra, Dalila, and ebony fo shopping. The money they have each is in the ratio

Cleopatra : Dalila : Ebony =

5 : 7 : 8

Cleopatra has $15.

A) How many dollars do they have in total?

B) Dalila spends 12$ on a hat, how many dollars does she have left?

A)

Total ratio=(5 +7 +8)= 20

Cleopatra has $15.

Let X = total money

Ratio of Cleopatra= 5/20 ×X=15

5X /20 = 15

5X= (15×20)

X= $60

They have $60 in total

B) ratio of Dalila= 7/20 × 60 = $21

But 12$ was spent by Dalila on a hat

Then Dalila will have ($21 - 12$) Left

= $9
