Hi there!

Amit's reasoning is incorrect because multiplying a positive number by a negative number results in a negative result. The question also says that it is a charge to his account, which means that money is being taken away. Therefore, Amit's reasoning is incorrect because the bank is taking away money from him and his equation results in a positive value, instead of negative.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

In Hawaii a volcano is about to explodel At 6:00 am a device placed inside the volcano
faust18 [17]

Complete question :

In Hawaii a volcano is about to explodel At 6:00 am a device placed inside the volcano

measures the temperature at 69.5 degrees Celsius. Every 3 minutes the temperature

rises 1/5 a degree. If the Volcano explodes at 145.5 degrees Celsius how many hours do

they have to evacuate a nearby city?​

Will Mark BRAINLIEST to the correct answer

Answer:

19 hours

Step-by-step explanation:

Given that:

Temperature of volcano at 6:00 am = 69.5°C

Average rise in temperature per 3 minute = 1/5

Hence, rise in temperature per minute = 0.0666666°C

Temperature at which volcano will explode = 145.5°C

Hence, change in temperature :

(145.5°C - 69.5°C) = 76°C

Hence, temperature will have to rise by 76°C

Rise in temperature / rate of temperature increase

= 76°C / 0.0666666°C

= 1140.0011 minutes

= 1140.0011 / 60

= 19.0000019 hours

= 19 hours

Answer:

24 oz has the lowest cost per ounce.

Step-by-step explanation:

12 oz ---> $2.49

1 oz --> $2.49/12

1 oz --> $0.2075

14 oz --> $3.15

1 oz --> $3.15/14

1 oz --> $0.225

20 oz --> $5

1 oz --> $5/20

1 oz --> $0.25

24 oz --> $4.56

1 oz --> $4.56/24

1 oz --> $0.19  ..........this is the lowest cost per ounce

36 oz --> $7.2

1 oz --> $7.2/36

1 oz --> $0.2

If point E is the midpoint of and point D is the midpoint of , which expression represents the value of s
iogann1982 [59]

The length of ED is half the length of AB.

<h3>What is the length?</h3>
  • Distance is measured by length.
  • Length is a quantity with the dimension distance in the International System of Quantities.
  • Most measurement systems use a base unit for length from which all other units are derived.
  • The meter is the foundation unit of length in the International System of Units.

Reasons:

The given parameters are;

In ΔABC, point E is the midpoint of AC

The midpoint of BC is the point D

Segment ED = s

Segment CE = p

Segment EA = r

Segment CD = q

Segment DB = t

Segment ED = s

Segment AB = u

Required:

The expression that represents the value of s.

Solution:

CE = 0.5 × AC Definition of midpoint

CD = 0.5 × CB Definition of midpoint

Therefore, we have;

\frac{CE}{AC} =\frac{CD}{CB} =0.5

Therefore, given that ∠C ≅ ∠C, by the reflexive property, we have;

ΔABC is similar to ΔCDE by Side-Angle-Side similarity

Which gives;

\frac{CE}{AC} = \frac{CD}{CB}  = \frac{ED}{AB} =0.5=\frac{1}{2}

ED = s and AB = u which gives;

\frac{ED}{AB}=\frac{s}{u}  =0.5=\frac{1}{2}

\frac{s}{u} =\frac{1}{2}

Which gives:

s=\frac{1}{2} *u

The expression that represents the value of s is; s = one-half u

Therefore, the length of ED is half the length of AB.

The question you are looking for is here:

If point E is the midpoint of segment AC and point D is the midpoint of segment BC, which expression represents the value of s? triangle CAB, point E is on segment AC between points A and C and point D is on segment BC between points B and C, creating segment ED, CE equals p, EA equals r, CD equals q, DB equals t, ED equals s, and AB equals u s equals p over q s = one half s equals q over p s = 2u
