Choose all that apply. What type of numbers represent parts of a whole?

Can someone do this for me please?! Just the answer pls

<h2>For the number 1..</h2>

<h2>angle at center = 2×angle at circumference</h2><h2>the angle at center (o) is equal to 141</h2>

therefore:

<h2>141 = 2x</h2><h2>divide both sides by 2</h2><h2>x = 70.5</h2>

option (A).

( the number 2 and 3 questions aren't correct )

A car travels 28 miles south and then 45 miles east around a lake. A boat leaves from the same place and arrives at the same pla

alexandr402 [8]

Answer:

The car travelled 73 miles

The boat travelled 53 miles

The car arrived 17.7 minutes before the boat

Step-by-step explanation:

The total distance the car travelled from Point A to Point B = 28+45 = 73 miles

The total distance the boat travelled is given by the displacement; Using Pythagorean theorem = 53miles.

Time taken by the car = Distance/Speed = 73/40 = 1.825 hrs or 109.5 minutes

Time taken by the boat = Distance/speed = 53/25 = 2.12 hrs or 127.2 minutes.

The time taken by the car is the shortest, therefore it arrives first before the boat.

This equation shows how the total number of appetizer recipes Emily knows depends on the number of weeks she attends culinary sc

Alexxandr [17]

Answer:

W=2

Step-by-step explanation:

First you have to fill A in as 19 because thats how many culinary recipes that she will need to know

Second you then have to get the variable W by itself so you would subtract 17 from the side that W is on

Once you subtract 17 from one side you have to subtract from the other

So therefore W would =2

Make w subject of formula C=(4+w)/(w+3)

grin007 [14]

Answer:

Step by Step Solution

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

c-((4+w)/(w+3))=0

STEP

1

:

4 + w

Simplify —————

w + 3

Equation at the end of step

1

:

(w + 4)

c - ——————— = 0

w + 3

STEP

2

:

Rewriting the whole as an Equivalent Fraction

2.1 Subtracting a fraction from a whole

Rewrite the whole as a fraction using (w+3) as the denominator :

c c • (w + 3)

c = — = ———————————

1 (w + 3)

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

c • (w+3) - ((w+4)) cw + 3c - w - 4

——————————————————— = ———————————————

1 • (w+3) 1 • (w + 3)

Equation at the end of step

2

:

cw + 3c - w - 4

——————————————— = 0

w + 3

STEP

3

:

When a fraction equals zero :

3.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

cw+3c-w-4

————————— • w+3 = 0 • w+3

(w+3)

Now, on the left hand side, the w+3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

cw+3c-w-4 = 0

Solving a Single Variable Equation:

3.2 Solve cw+3cw-4 = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

We shall not handle this type of equations at this time.
