A cookie recipe calls for 1.5 cups of sugar for two dozen cookies. How many cups of sugar are needed for one dozen cookies?? Plss help!!!
For a dozen cookies, 0.75 cups of sugar are needed in total.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
given, A cookie recipe calls for 1.5 cups of sugar for two dozen cookies.
Since,
For two dozen of cookies, there are a total of 1.5 cups of sugar required.
In 2 dozen cookies, required sugar = 1.5 cups
In 1 dozen cookies, required sugar = 1.5/2 cups
In 1 dozen cookies, required sugar = 0.75 cups
Therefore, The total number of cups of sugar required for one dozen cookies is 0.75.

A car covers a distance of 189km in 4.5 hours, what is the average speed
Step-by-step explanation:
The average speed is 42 km/hr.
To calculate the average speed, you divide the total distance by the time it took to travel that distance:
189 km / 4.5 hours = 42 km/hr
[tex]\texttt{speed}=\dfrac{d}{t}[/tex]
distance = 189 km
time = 4.5 hours
[tex]\texttt{speed}=\dfrac{189}{4.5}[/tex]

Consider the line y=7x-3.
Find the equation of the line that is parallel to this line and passes through the point (-4,-6).
Find the equation of the line that is perpendicular to this line and passes through the point (-4, -6).
The equation of the line that is parallel to this line and passes through the point (-4,-6) is y = 7x + 22
The equation of the line that is perpendicular to this line and passes through the point (-4,-6) is y = -(1/7)x - 46/7
What is an equation?An equation is an expression showing the relationship between two or more numbers and variables. An equation can either be linear, quadratic, cubic and so on depending on the degree.
The slope intercept form of a line is:
y = mx + b
where m is the slope and b is the y intercept
Two lines are parallel if they have the same slope and are perpendicular if the product of their slope is -1.
Given the line:
y = 7x - 3
The slope is 7. The line parallel to this line would also have a slope of 7, while the line perpendicular have a slope of -1/7
The equation of the line that is parallel to this line and passes through the point (-4,-6) is:
y - (-6) = 7(x - (-4))
y = 7x + 22
The equation of the line that is perpendicular to this line and passes through the point (-4,-6) is:
y - (-6) = (-1/7)(x - (-4))

Find Sn for the arithmetic series where a1= 3 , an= 36, n= 12
Find sn for the arithmetic series where a1= 3, d= 2, n= 100
The value of the sum of the series is are 234 and 10200
How to determine the sum of the seriesIn an arithmetic series, the sum of the first "n" terms (Sn) is given by the formula:
Sn = n/2 * (a1 + an)
Where "a1" is the first term and "an" is the nth term.
For the first series, we have
In this series, a1=3 , an=36 , n=12
Plugging these values into the formula, we get:
Sn = 12/2 * (3 + 36)
Sn = 234
For the second series, we have
In this series, a1=3 , d = 2 , n=100
So, we have
an = a + (n - 1)d = 3 + 99 * 2 = 201
Plugging these values into the formula, we get:
Sn = 100/2 * (3 + 201)
Sn = 10200

The mean of the waiting times in an emergency room is 80.2 minutes with a standard deviation of 10.5 minutes for people who are admitted for additional treatment. The mean waiting time for patients who are discharged after receiving treatment is 120.6 minutes with a standard deviation of 18.3 minutes. Which times are more variable?
The variance for waiting times for patients who are discharged after receiving treatment is more, so waiting times for patients who are discharged after receiving treatment is more variable.
What is variance?In probability and statistics, variance is the actual value of the squared variation of a stochastic process from its mean value. Informally, variance calculates the degree to which a random group of numbers deviates from the mean value.
Another essential tool, the measurement of variance is equal to the square of the standard deviation.
Since the variance for waiting times for patients who are discharged after receiving treatment is more, so waiting times for patients who are discharged after receiving treatment is more variable.

Answer:
Sunrise: 95x5+25 = 500
Bright Eyes: 110x5= 550
Sunrise Will be 50$ Cheaper
oops sorry did my math wrong
Answer: Sunrise Hotel is cheaper by $50
Step-by-step explanation:
First, you do $95 x 5 nights = $475, and then add $25 and get $500 per night (Sunrise).
Then multiply $110 and 5 nights and get $550 per night (Bright Eyes).
Lastly, subtract $550 and $500 and get $50.
A cylinder has a height of 10cm.
The diameter of the cylinder is
4/5
its height.
Calculate the volume of the cylinder in terms of π.
The radius is the center of circle to its edge or half of a diameter so half of 4/5 is 0.4 since 0.8 / 2 = 0.4.
To find the volume we need to do the equation π r² h.
So, π x 0.4^2 x 10 = 5.02654825.
Round 5.02654825 to the nearest hundredth and it is 5.03.

To begin a bacteria study, a petri dish had
2700
bacteria cells. Each hour since, the number of cells has increased by
17%
.
Let
t
be the number of hours since the start of the study. Let
y
be the number of bacteria cells.
Write an exponential function showing the relationship between
y
and
t
The exponential equation is y = 2700 ( 1 + 0.17 )ⁿ , where n = t , the number of hours since the start of the study
What is exponential growth factor?The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the exponential equation be represented as y
Now , the number of bacteria cells = y
The number of hours since the start of the study = n = t
The initial number of bacteria = 2,700 cells
The percentage of increase in the cells = 17 %
So , The exponential growth formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
Substituting the values in the equation , we get
y = 2700 ( 1 + 0.17 )ⁿ
On simplifying the equation , we get
y = 2700 ( 1.17 )ⁿ
where n = t , the number of hours since the start of the study
Hence , the equation is y = 2700 ( 1.17 )ⁿ

Use formula to find the area of the figure
The area of the figure in this problem is given as follows:
A. 30 in².
How to obtain the area of the figure?The area of a triangle is given by half the multiplication of the base length by the height of the triangle.
Applying the Pythagorean Theorem, we can obtain the missing side length, as follows:
4² + x² = 6²
x² = 36 - 16
x² = 20
x = square root of 20
x = 4.47.
For a right triangle, one side is considered the height of the other, hence the sides are:
4 in.4.47 + 8 = 12.47 in.Hence the area of the triangle is then obtained as follows:
Area = 0.5 x 4 x 12.47
Area = 25 in².

The perimeter of a rectangular sports court is 148 feet. After a game, a player's coach estimates that the athlete has run
a total of 353 feet, which is equivalent to four times the court's length plus seven times its width. What are the
dimensions of the sports court?
The length is
feet.
Answer: Let's call the length of the rectangular court "L" and the width "W". Then, the perimeter of the court is 2 * (L + W) = 148 feet, so 2 * L + 2 * W = 148 feet.
And, according to the coach's estimate, the athlete ran a total of 4 * L + 7 * W = 353 feet.
We can use these two equations to find the dimensions of the court. Solving the first equation for W:
W = (148 - 2 * L) / 2.
Substituting this expression for W into the second equation:
4 * L + 7 * (148 - 2 * L) / 2 = 353
Expanding and simplifying the right side of the equation:
4 * L + 74 - 7 * L = 353
-3 * L = -279
L = 93 feet.
Finally, using the expression for W from the first equation:
W = (148 - 2 * L) / 2 = (148 - 2 * 93) / 2 = 32 feet.
So the dimensions of the sports court are 93 feet by 32 feet.

A cuboid has the total surface area 1168 cm². If it's length and breadth are 16 cm and 14 cm respectively, what it's height?
A cuboid has 6 faces and the formula for its total surface area is:
2lw + 2lh + 2wh, where l is the length, w is the breadth, and h is the height.
Given the total surface area of 1168 cm² and the length and breadth being 16 cm and 14 cm, respectively:
2(16)(14) + 2(16)h + 2(14)h = 1168
Expanding the expression:
448 + 32h + 28h = 1168
Combining like terms:
60h = 720
Dividing both sides by 60:
h = 12 cm
So the height of the cuboid is 12 cm.
