Answer:
Step-by-step explanation:
We are given that
Initially the difference between the cake's and the cooler's temperature ,a=50 degree Celsius
We have to find the function that gives the temperature difference in degrees Celsius D(t).
We know that
Substitute the values
This is required function that gives the temperature difference in degrees Celsius.
Answer:
<h2>3500</h2>
Step-by-step explanation:
Given the ratio of the profit, cost of materials and labour in the production of
an article to be 5:7:13 respectively, total ratio = 5+7+13 = 25
If the cost of labour is x, the cost of material will be 840+x (since the cost of materials is Le 840 more than that of labour) .
Let the total cost of producing the article be y.
Cost of labour = 13/25 * y = x
Cost of labour = 13y/25 = x.................... 1
Cost of material = 7/25*y = 840+x
Cost of material = 7y/25 = 840+x ..................... 2
From 1, 13y = 25x
x = 13y/25 ................... 3
Substituting equation 3 into 2:
7y/25 = 840+x
7y/25 = 840+13y/25
collect the like terms:
7y/25 - 13y/25 = 840
-6y/25 = 840
-6y = 25*840
y = 25*840/6
y = 3,500
<em>Hence the total cost of producing the article is 3500</em>
Answer:
Question 6: the slope is 3
Question 7: 5
Question 8: y=3x+5
Step-by-step explanation:
Using rise over run, You can see that it is 3 in rise and 1 in rise. 3/1 is 3. The y-int is 5 because that is where it touches the y-axis. The formula is y=mx+b where m is slope and b is y-int. Sub the other answers in to find the answer. Hope this helps! Pls mark brainliest!
