Answer:

1,0472 rad

Step-by-step explanation:

ANGLE MEASURES

Generally two measuring systems are used:

1. The sexagesimal system, whose unit is the degree: º

A sexagesimal degree is the amplitude of the angle resulting from dividing the circumference into 360 equal parts.

2. The radial system whose unit is the radian: rad

A radian is the measure of the center angle of a circle whose arc length coincides with the length of its radius.

<u>CONVERSION OF GRADES TO RADIANS </u>

To convert an angle of degrees to radians or vice versa, what must be done is a rule of three, considering that:

360° = 2π radians

Calculation

(60° * 2π rad) /360° = 1.0472 rad

If baby potatoes costs 1.62 and if green beans costs 2.54 and vera bought 2.625 pounds of potatoes and 1.5 pounds of green beans
Svetradugi [14.3K]

Vera's change will be $1.94

Baby potatoes= 1.62

Green beans= 2.54

Amount spent on potatoes= 1.62×2.625

= 4.25

Amount spent on beans= 2.54× 1.5

= 3.81

The change can be calculated as follows

= 3.81 + 4.25

= 8.06

10-8.06

= 1.94

Hence the change is $1.94

PLZ help I will mark as brainliest
Elden [556K]

Answer:

  6750 - 3894 = 2856

Step-by-step explanation:

You have to make use of the arithmetic facts you know.

The least-significant asterisk must be 0, because the sum of 4 and 6 is 10.

The 10s asterisk must be 9,so that the sum 5 + 9 + 1 has a least-significant digit of 5.

The 100s asterisk must be 7, because that is the least-significant digit of the sum 8 + 8 + 1 = 17.

The 1000s asterisk must be 3, so that 2 + 3 + 1 = 6.

(The "1" in each of these sums is the carry from the sum of the digits with the next lower place value.)

So, the subtraction problem is ...

  6750 - 3894 = 2856

_____

<em>Comment on the solution method</em>

For the most part, we worked this as an addition problem. The sum of the last two numbers must be equal to the first: 6570 = 3894 +2856. For some of us, addition facts are easier to work with than subtraction facts. The carry/borrow can be less confusing that way.

A washer and dryer cost $600 combined. The cost of the washer is three times the cost of the dryer
Sveta_85 [38]
First, assign two variables to the prices of the two appliances.
'w' will represent the price of a washer, and 'd' will represent the price of a dryer.

Because "the washer is three times the cost of the dryer," we can form this equation:
w = 3d
On top of that, we know the washer and dryer add up to 600, making another equation.
w + d = 600

Because we know the value of 'w,' we can input that into the equation 'w + d = 600'
(3d) + d = 600
Simplify:
4d = 600
d = 150

Since the washer is three times the price of the dryer:
w = 3(150) = 450

The dryer costs $150, and the washer costs $450.

PLS HELP MEE ASAP 1 MIN LEFT HELPP!!!!!!!!!
artcher [175]

Answer: BC = 5.83

Step-by-step explanation:

Luckily, the triangle is placed on the graph nicely so we can count the legs of the triangle:

AB = 5

AC = 3

BC = ?

To find BC, we can simply use the Pythagorean Theorem:

a^{2}+b^{2}=c^{2}

5^2 + 3^2 = c^2

25 + 9 = c^2

34 = c^2

Now square root to find c, or BC.

\sqrt{34}=\sqrt{c^{2} }

c = 5.83 (rounded by nearest hundredth)
