there were 145 boys on the honor role and 60 girls equally given a total number of 205. This year, the number of boys decreased by 20% = 0.2*145=29
145-29=116
116 is this year number of boys on honor role
For girls.
=0.25*60=15
60-15=45
45 is this year number of girls on honor role.
Total number of students on honor role this year is 116+45 =161
Percentage of decrease = 1 -(161/205)*100% =( 1-0.785)*100
= 0.215*100
= 21.5%
Answer:
f(-5) = 5
Step-by-step explanation:
Step 1: Define
f(x) = -x² - 7x - 5
f(-5) is x = -5
Step 2: Substitute and Evaluate
f(-5) = -(-5)² - 7(-5) - 5
f(-5) = -25 + 35 - 5
f(-5) = -25 + 30
f(-5) = 5
Answer:
3
Step-by-step explanation:
3/3=1 which is smaller then 2
<u>QUESTION :</u>
Find the given value of each angle for the following supplementary angles must add up to 180
- one angle = (5x-13)°
- another angle = (11x+65)°
➱<em>ᴛʜᴇ ᴛᴡᴏ ᴀɴɢʟᴇs ʟɪᴇs ᴏɴ ᴛʜᴇ sᴀᴍᴇ ʟɪɴᴇ</em>
➱ѕσ ѕυм σƒ вσтн тнє αηgℓєѕ = 180°
therefore ,
⤳(5x-13)° + (11x+65)° = 180°
⤳5x -13° + 11x + 65° = 180°
⤳16x + 52° = 180°
⤳16x = 180° - 52°
⤳16x = 128°
⤳x = 128 /16

hence ,
the two angles will be
⇛<u>ᴏɴᴇ ᴀɴɢʟᴇ</u> :
<em>➛</em>(5x-13)°
<em>➛</em>5(8) - 13
<em>➛</em>40 - 13

⇛<u>ᴀɴᴏᴛʜᴇʀ ᴀɴɢʟᴇ</u> :
<em>➛</em><em> </em>(11x+65)°
<em>➛</em>11(8)+65
<em>➛</em>88 + 65
