Answer:
12 minutes
Step-by-step explanation:
Let c and h represent the filling times for the cold and hot taps, respectively. When the cold tap is 1/2 open, we presume that means the filling time becomes 2c.
In terms of baths per minute, the relationships are ...
1/c + 1/h = 1/3
1/(2c) +1/h = 1/(3 +1.8) . . . . . 1:48 min:sec is 1.8 minutes
Subtracting the first equation from twice the second, we get ...
2(1/(2c) +1/h) -(1/c +1/h) = 2(1/4.8) -(1/3)
1/h = 2/4.8 -1/3 = 1/12
h = 12
It takes the hot tap 12 minutes to fill the tub alone.
Consider 8x2 - 48x = -104.

a local food company produces yogurt in 3/4 tab cups 2 cups= 1 pint 2 pints= 1 quart 4 quarts= 1 gallon 8 fl oz= 1 cup The tubs of yogurt are sold for 75¢ each. Twenty percent of this is profit for the food company. How much profit does the company make on each tub? Enter the answer in decimal form.
Answer:
15cents.
Step-by-step explanation:
The cost of yogurt is $0.75
20% of this amount is the profit to the company
Profit = [tex]\frac{20}{100} * 0.75[/tex]
= $0.15
So the profit to the company is 15cents.

Answer:
its hard to do this without a graph to draw on for you but see explanation
Step-by-step explanation:
from each point count how many units it is from the mirror line and then count that many in the opposite direction. for example, the top left point is 3 away from the mirror line from the left so count 3 units to the right of the mirror line and that is where that point will be.

Which of the following equations is equivalent to 1.43p + 2.2 = -4.001?
A. 143p + 22 = -4001
B. 143p + 220 = -4001
C. 1430p + 2200 = -4001
D. 143p + 220 = -4001
We can say that equation (C) [1430p + 2200 = -4001] is equivalent to the given equation [1.43p + 2.2 = -4.001].
What do we mean by equations?The equal sign joins two expressions to create a mathematical formula called an equation. An equation is a claim that demonstrates the equality of two mathematical expressions, according to algebra. For instance, the equation 3x + 5 = 14 is made up of the two equations 3x + 5 and 14, which are separated by the equal sign.So, the equivalent expression is:
Equation is: 1.43p + 2.2 = -4.001Let us take the number with the most numbers after decimals, that is -4.001.
Now, if we -4.001 × 1000, then we obtain:
-4.001 × 1000 = -4001This means we will multiply all terms with 1000 as follows:
1000(1.43p + 2.2 = -4.001)1430p + 2200 = -4001Therefore, we can say that equation (C) [1430p + 2200 = -4001] is equivalent to the given equation [1.43p + 2.2 = -4.001].

Use the table to find the residual points. A 4-column table with 5 rows. The first column is labeled x with entries 1, 2, 3, 4, 5. The second column is labeled given with entries negative 0.7, 2.3, 4.1, 7.2, 8. The third column is labeled predicted value with entries negative 0.28, 1.95, 4.18, 6.41, 8.64. The fourth column is labeled residual value with all entries blank. Which residual plot is the correct one for the data? A graph shows the horizontal axis numbered negative 1 to positive 7 and the vertical axis numbered negative 1.5 to positive 1.5. Points are scattered all over the graph. A graph shows the horizontal axis numbered negative 1 to positive 7 and the vertical axis numbered negative 1.5 to positive 1.5. Points are scattered all over the graph.

A graph shows the horizontal axis numbered negative 1 to positive 7 and the vertical axis numbered negative 1.5 to positive 1.5. Points are scattered all over the graph.
Answer:
B
Step-by-step explanation:
residual is the given - predicted
residual 1: -0.42
residual 2: 0.35
so on and so forth
B matches up with the first two coordinates
The residuals are 0.42, 0.35, -0.08, 0.79, and -0.65 because residuals are the difference between the actual and predicted.
What is the line of best fit?A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.
The residual = actual—predicted
We have given:
X Given Predicted Residual value
1 0.7 0.28 0.42
2 2.3 1.95 0.35
3 4.1 4.18 -0.08
4 7.2 6.41 0.79
5 8 8.65 -0.65
Thus, the residuals are 0.42, 0.35, -0.08, 0.79, and -0.65 because residuals are the difference between the actual and predicted.

URGENT BRAINLIEST DUE IN 5 MINUTES PART 1 Clare estimates that her brother is 4 feet tall. When they get measured at the doctor's office, her brother's height is 4 feet, 2 inches.
Which measurement should be considered the actual height?
Answer:

Step-by-step explanation:
The height that was measured by the doctor should be considered the actual height because it is the most accurate. It is an actual measurement and not an estimate.
Students in the Scott School District spent two weeks collecting a total of 5,853 books to donate to local hospitals. The first week, the students collected 2,054 books. About how many books did the students collect for the hospitals the second week? Choose the better estimate.
Answer:
3799 books
Step-by-step explanation:
We have the total number of books collected as 5,853 books
In the first week, a total of 2,054 books were collected.
If the collection of books went on for two weeks;
Hence in the second week, a total of (5,853 - 2,054) were collected.
Therefore, number of books collected in the second week = 3799 books
17y-5x+8=9 in standard form?
Answer:
-5X + 17Y -1 A = -5X B = 17Y. C = -1
Step-by-step explanation:
follow me say a thanks mark me branliest
The equation of a line 17y - 5x + 8 = 9 in standard form
is - 5x + 17y - 1 = 0.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
Given, 17y - 5x + 8 = 9 we have to convert in standard form Ax + By + c = 0.
∴ 17y - 5x + 8 = 9.
- 5x + 17y - 1 = 0.
So, A = - 5, B = 17 and, c = - 1.
