Answer:

2 5/8

Step-by-step explanation:

To determine half of 5 1/4, you divide by 2:

5 divided by 2 equals 2 1/2

And, 1/4 divided by 2 results in 1/8

Next, unify the denominators

1/2, 2/4, 4/8

1/8,

Afterwards, combine them

2 4/8+1/8=2 5/8

2. Peter drew two rays, AC and AP with A as a common endpoint. Which of the following statements
PIT_PIT [12445]

The complete question reads:

Peter created two rays, AC and AP, sharing a common vertex at point A. Which of the following statements

might accurately describe Peter's drawing?

I. AC and AP are parallel.

II. PAC represents an angle.

III. AC and AP are at right angles.

A. I and II

B. II and III

C. I and III

D. I, II, and III

Answer:

Option B: II & III

Step-by-step explanation:

We know Peter has drawn rays AC and AP.

Since the point A is shared as the endpoint, it indicates an angular relationship at this common point.

This angle could potentially be 90°, suggesting that rays AC and AP may be perpendicular.

Thus, the valid statements that characterize his drawing are: II & III.

A job calls for installing 270 lighting fixtures. If 81 fixtures have been installed so far, what
tester [12383]
70%Step-by-step explanation:First, determine how many fixtures are left to install.270-81=189. The fraction representing the work still to be done is the count of fixtures to install divided by the total amount. So, % of work remaining equals 189 divided by 270, which equals 0.7. Converting this to percentage form gives us 0.7 * 100% = 70%.

Threatened monarch butterflies are monitored by measuring the area occupied by overwintering butterflies in Mexico. According to
Leona [12618]

Answer:

14.2 hectares

Step-by-step explanation:

Fund Mexico reports that monarch butterflies occupied 1.13 hectares in one winter and 4.01 hectares the next winter (one year later)

The Geometric growth formula is

(Pt/ Po)^1/t

Where Pt = Size after t years = 4.01 hectares

Po = Initial size = 1.13

t = time = 1

=( 4.01/1.13 )^1/1

= 3.5486725664

Thus, the geometric growth rate is 3.5486725664.

The area they will occupy in hectares after one more year = Current area × Geometric growth rate

= 4.01 ×3.5486725664

= 14.230176991 hectares

Approximately equal to 14.2

The budget of a university organizations is split evenly among its various committees . if they have a budget of P 60.000 repres
PIT_PIT [12445]

Response:

m(n) = 60000

Amount = 60000/n

Step-by-step breakdown:

Provided

Budget = 60000

Solving part (a) as a function mn

To achieve this, simply substitute m(n) for the budget amount.

This results in;

m(n) = 60000

Solving part (b) for the amount each committee is allocated.

Given that the budget will be evenly split.

Amount = m(n)/n

Replace m(n) with 60000

Amount = 60000/n

A college runner set a school record of 3:59.37 in the mile run. assuming that the distance was measured accurately to five sign
AnnZ [12381]
Given a time of 3:59.37 for a mile run, this translates to 3 hours and 59.37 minutes. To convert this entirely into hours: 3 hours + 59.37 minutes (1 hour / 60 minutes) = 3.9895 hours. Thus, the average speed can be calculated as: average speed = 1 mile * (1.61 km / mile) / 3.9895 hours. Consequently, the average speed equals 0.4 km / hour.
