Step-by-step explanation:
litres of milk
30/100=x/125
10x=375
x=37.5
14% of milk
14/100=x/125+y
1750+14y=100x
1750=100x–14y
1750=100(37.5)–14y
1750=3750–14y
y=2000/14=142.9

Out of 1,000 students, 80 were asked by random sampling what color they would prefer for their first car. Their responses are shown in the table below.
Answer:
175
Step-by-step explanation:
To find a proportion, you need to put both parts over the total. You would put the part of silver (14) over the total (80) and the part you are trying to find (X) over the total number of students (1,000). Then you cross multiply 14 x 1,000 and divide by 80 giving you 175 silver cars.
The profits of Mr. Cash's company is represented by the equation 푃 푡 =−3푡 ) +18푡−4, where 푃(푡) is the amount of profit in hundreds of thousands of dollars and 푡 is the number of years of operation. He realizes his company is on the down turn and wishes to sell before he ends up in debt.
Answer:
- Mr Cash's company business shows the maximum profit in 3 years after starting the business.
- The maximum profit = 23 thousand dollars = $23,000
- Anytime beyond 5.77 years will be too late to sell the business as the profit margins have entered negative values.
Step-by-step explanation:
Complete Correct Question
The profits of Mr. Cash’s company is represented by the equation
p(t)=-3t^2+18t-4,
where p(t) is the amount of profit in hundreds of thousands of dollars and t is the number of years of operation. He realizes his company is on the down turn and wishes to sell before he ends up in debt.
In what year of operation does Mr. Cash’s business show maximum profit? What is the maximum profit? What time will it be too late to sell business?
Solution
The profit function is given as
p(t) = -3t² + 18t - 4
p(t) = profit in thousand of dollars
t = time in years.
To find the year where the maximum profit is obtained, we use differentiation analysis to obtain the maximum of the profit function and the corresponding time where it occurs.
At the maximum of the profit function,
(dp/dt) = 0 and (d²p/dt²) < 0
p(t) = -3t² + 18t - 4
(dp/dt) = -6t + 18
At maximum profit
(dp/dt) = -6t + 18 = 0
6t = 18
t = (18/6) = 3 years.
(d²p/dt²) = -6 < 0
Hence, this value of t corresponds to the maximum value of the profit function.
The maximum profit is then obtained when t = 3
p(t) = -3t² + 18t - 4
p(3) = -3(3²) + 18(3) - 4 = 23 thousand dollars
The business will be late to sell when the profits from the business start to run into negative values. So, we obtain the time when the profit margins reaches 0.
p(t) = -3t² + 18t - 4 = 0
-3t² + 18t - 4 = 0
Solving the quadratic equation
t = 0.23 years or t = 5.77 years
Since the profits first start rising from the value at t=0 up till the maximum profit at t=3, 0.23 years isn't a realistic point to sell the business as this is part of the onset of profits, but beyond 5.77 years on the other hand represents when the business stops to bringing in profits and leads to losses.

6- en la clase de repostería, inés y liz prepararon una torta de naranja. para ello, utiliza 1/2 litro de leche y 1/3 de jugo de naranja¿que cantidad de líquido utilizan? ¿cuantos litros de leche más que jugo de naranja echan?
Answer:
El total de líquido utilizado es [tex]\frac{5}{6} de litro[/tex]. Se echa [tex]\frac{1}{6}[/tex] de litro más de leche que de jugo
Step-by-step explanation:
Para saber la cantidad total de líquido, basta con sumar las cantidades de leche y de jugo de naranja. Vamos a asumir que usa 1/3 de litro de jugo de naranja.
En este caso el total de líquido es 1/2 litro + 1/3 litro. Dado que estas fracciones tienen distinta denominador, debemos sumarlas de la siguiente manera
[tex] \frac{1}{2}+\frac{1}{3} = \frac{1\cdot 3 + 2\cdot 1}{2\cdot 3} = \frac{5}{6}[/tex]
Para calcular la cantidad extra de leche de más que la cantidad de jugo, restamos estos números. Es decir
[tex] \frac{1}{2}-\frac{1}{3} = \frac{1\cdot 3 - 2\cdot 1 }{2\cdot 3} = \frac{1}{6}[/tex]
Es decir, que echamos [tex]\frac{1}{6}[/tex] de litro más de leche que de jugo.

Justin's rice ball recipe uses 100 grams of rice to make 1 rice ball. Justin has 700 grams of rice.
Answer:
Yup he can make 7 rice balls
Step-by-step explanation:
If he has 700 grams of rice and he only needs 100 grams welp that's 700/100
first you can take the zeros off so it turns into 7/1 and anything devided by it's self is itsself
So 7/1 is 7
Justin can make 7 rice balls if he has 700 grams of rice because he can make 1 rice ball using 100 grams.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We have:
Justin's rice ball recipe uses 100 grams of rice to make 1 rice ball.
The ratio of the quantity of the rice to rice ball:
100:1
Multiply the above ratio by 7
700:7
Thus, Justin can make 7 rice balls if he has 700 grams of rice because he can make 1 rice ball using 100 grams.

Answer: -3
Step-by-step explanation:
Let's solve your equation step-by-step.
19+12k=−k−20
Step 1: Simplify both sides of the equation.
19+12k=−k−20
19+12k=−k+−20
12k+19=−k−20
Step 2: Add k to both sides.
12k+19+k=−k−20+k
13k+19=−20
Step 3: Subtract 19 from both sides.
13k+19−19=−20−19
13k=−39
Step 4: Divide both sides by 13.
13k /13 = −39/13

Which set of ratios could be used to determine if one triangle is a dilation of the other?
A triangle with side lengths 3.6, 5.4, 6. A triangle with side lengths 3, 4.5, 5.
StartFraction 3.6 Over 3 EndFraction = StartFraction 5.4 Over 4.5 EndFraction = StartFraction 6 Over 5 EndFraction
StartFraction 3.6 Over 3 EndFraction = StartFraction 4.5 Over 5.4 EndFraction = StartFraction 6 Over 5 EndFraction

StartFraction 3 Over 4.5 EndFraction = StartFraction 3.6 Over 5.4 EndFraction = StartFraction 5 Over 6 EndFraction
Answer:
Option (1).
Step-by-step explanation:
Dimensions of two triangles have been given as 3.6, 5.4, 6 units and 3, 4.5, 5 units.
If triangle one is dilated to form triangle two, then the ratio of the sides will be
Ratio = [tex]\frac{\text{Side of triangle (1)}}{\text{Corresponding side of triangle (2)}}[/tex]
= [tex]\frac{3.6}{3}[/tex]
Similarly, ratio of other two sides will be = [tex]\frac{5.4}{4.5}[/tex] and [tex]\frac{6}{5}[/tex]
Since the triangle (1) was dilated to form triangle (2), so both triangles will be similar and the ratios of their corresponding sides will be equal.
Therefore, Ratios of the sides = [tex]\frac{3.6}{3}=\frac{5.4}{4.5}=\frac{6}{5}[/tex]
Option (1) will be the answer.
