Answer:

Pakisuri ang paliwanag

Step-by-step explanation:

Base sa sumusunod na impormasyon:

Sa unang tatlong oras ng bagyo: rate ng pag-ulan = 25mm bawat oras

Ang bagyo ay bumagal ng isang oras: pagkatapos ay nagsimula ang pag-ulan muli sa tuloy-tuloy na rate na 20 mm bawat oras sa susunod na 2 oras

Ang piecewise function na nagmomodelo ng pag-ulan bilang isang function ng oras

Halaga ng Pag-ulan bilang function ng oras = f(t)

f(t) = 25t ; kung t≤ 3

Kapag bumagal ang bagyo ng isang oras :

f(t) = 0;

f(t) = 25*3 ; para sa t ∈ (3, 4)

Pagkatapos ay ang pag-ulan sa tuloy-tuloy na rate na 20mm para sa isa pang 2 oras

f(t) = (25 *3) + 20(t - 4) ; para sa t ∈ (5, 6)

babunello [11817]
Jay's bread has risen to 220% of its initial size. The question, as it stands, is incomplete. What is missing would clarify: Jay's bread increases to 11/5 of its original size after three hours. To determine the percentage of its original size: New bread size = units when dough is at 11/5 of its original size.

If m abf=7b-24 and m Abe = 2b what is m EBF
Inessa [12570]
Since m∠abe = 2b, and angle abe consists of angles abf and ebf, we can write:
m∠abe = m∠abf + m∠ebf
To find m∠ebf, rearrange:
m∠ebf = m∠abe - m∠abf
Substitute the given expressions:
m∠ebf = 2b - (7b - 24)
Simplify:
m∠ebf = 2b - 7b + 24
m∠ebf = -5b + 24.

Yuson must complete 210 min of community service. She does 30 min each day. Which linear equation represents the number of minut
PIT_PIT [12445]

Answer:

Comprehensive explanation:y=-30x+210

Let's denote

x -----> the number of days

and

y ----> the remaining minutes for Yuson

We know that

The linear equation in slope-intercept form can be represented as

y=mx+b

here

m indicates the slope

b represents the y-coordinate of the y-intercept (starting value)

In this scenario, we have

The slope is defined as

m=-30\frac{min}{day} ----> negative, as it indicates a decreasing function

b=210\ min ----> initial value

substituting the values

y=-30x+210
