Given :

Kareem heats a beaker of water to boil. Then he records that the water temperature decreases from 100° C to 19° C in 5 2/5 minutes.

To Find :

What was the charged in temperature each minute.

Solution :

Time taken to reach 19° C :

T = 5\dfrac{2}{5}= \dfrac{27}{5}\ min

Now, change in temperature per minute is given by :

R =\dfrac{19^{o}-100^o}{\dfrac{27}{5}}\\\\R = -15 \ ^oC/ minute

Therefore, the charged in temperature each minute is -15 °C/minute .

Hence, this is the required solution.

PLEASE HELP<br>what is the value of x? enter your answer in the box​
Mashcka [7]

Answer: 3

For this question, we will use the angle bisector theorem.

Angle Bisector Theorem: In geometry, the angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle.

Now let's place it according to a general formula.

x/2.25 = 4/3

x= 4/3 * 2.25

x= 3

There you go! now you know the answer and the way to do it! Brainliest pweasee if the answer is correct and helpful!

16^5/4•16^1/4/(16^1/2)^2
Kazeer [188]

Answer:

The simplified expression is 16^-1/6

Step-by-step explanation:.

16^5/4•16^1 /4/ (16^1/2)^2

The dot means multiplication. The expression is rewritten as

16^5/4 × 16^1/4 / (16^1/2)^2

Recall the following rules of indices

1) y^a × y^b = y^(a+b)

2) (y^a)^b = y^ab

y^b/ y^a = y^(b-a)

Applying these rules of indices

16^5/4 × 16^1/4= 16^((5/4×1/4) = 16^((5/16)

(16^1/2)^2= 16^ 1/2×2 = 16^1 = 16

Therefore

16^5/4 × 16^1/4 / (16^1/2)^2

= 16^(5/16) /16

=16^(5/6) × 16^-1

= 16^ (5/6)-1

= 16^-1/6)

,The simplified expression is 16^-1/6

a plumber charges $55 for a service call, plus $35 per hour. If the plumber bill was $160 ,then how many hours was he there
marysya [2.9K]

Answer:

he was there 3 hours

Step-by-step explanation:

so you take 160 and subtract 55 from that number

160-55=105

next take 105 and divide that by 35 to get how many hours he was there.

105÷35=3

if you need this in slope intercept for a graph you use the equation where y = the total money spent

y=35x+55
