Plug in values; 2.5·4.3
Area ; 10.75
Answer:
Formula: bh
Plug in Values: 4.33 and 2.5
Area: 10.825 inches squared
Step-by-step explanation:
Before anything, when you converted 4 1/3 to 4.3, I recommend doing 4.33. ‘Ight, let’s begin.
The formula is base times height, therefore, you multiply the base (2.5) times the height (4.33).
2.5x4.33=10.825

How many possible triangles can be created if measure of angle A equals pi over 6 comma c = 18, and a = 9?
0 triangles
1 triangle
2 triangles
Cannot be determined based on the given information
If the measure of angle A equals pi over 6, the angle c equals 18, and the angle an equals 9, triangles may be formed.
When do three lines join to make a triangle?You only need to apply the Triangle Inequality Theorem, which asserts that the sum of a triangle's two side lengths is always greater than the third side. A triangle will exist if this holds true for each of the three possible added side length combinations.
From the given information, we have that:
m<B = pi/6 = 30 degres
c = 10
b = 5
This shows that we can use the cosine rule to find the third side b of the triangle. Since all the sides are complete, hence we can use the information given to find just 1 triangle

The area of a rectangular room is 750 square feet. The width of the room is 5 feet less than the length of the room. Which equations can be used to solve for y, the length of the room? Select three options. y(y + 5) = 750 y2 – 5y = 750 750 – y(y – 5) = 0 y(y – 5) + 750 = 0 (y + 25)(y – 30) = 0
Answer: option b), option c), and option e) are correct options.
Step-by-step explanation:
Given:
The area of a rectangular room= 750 square feet
The width of the room = 5 feet less than the length of the room
The length of the room = Y
To find:
Equations that can be used to solve the value of Y i.e. the length of the rectangular room.
Solution:
The equation can be derived from using the following formula:
Area of rectangle = length * width
According to the question,
Length of the rectangular room = Y
Width of the rectangular room = 5 feet less than the length of the room
= (Y-5)
Since, Area of rectangle = length * width
Area of the rectangular field = length of the room* width of the room
750 = Y (Y – 5) ………..eqn. (1)
Or, the above equation can be solved a step further and written as
750 = Y2 – 5Y ………..eqn. (2)
750- Y2 + 5Y= 0 ………..eqn. (3)
750-Y (Y- 5) =0 ………..eqn. (4)
Apart from the above equations, if we solve eqn. (2) we get the following equation:
750 = Y2 – 5Y
Y2 – 5Y- 750= 0
Y2 – 30Y + 25Y- 750 = 0
Y (Y- 30) + 25 (Y- 30) = 0
take Y- 30 common from L.H.S.
(Y -30) (Y+ 25) = 0 …………….eqn. (5)
Hence, the correct options are option b), option c), and option e).

The solution to the given quadratic equation is x = -1 + 3i OR x = -1 - 3i
Solving Quadratic equationsFrom the question, we are to solve the given quadratic equation
From the given information,
The quadratic equation is
x² + 2x + 10 = 0
Using the Quadratic formula,
x = [-b ± √(b² - 4ac)] / 2a
From the equation,
a = 1, b = 2, and c = 10
Then,
x = [-b ± √(b² - 4ac)] / 2a
x = [-(2) ± √((2)² - 4(1)(10))] / 2(1)
x = [-2 ± √(4 - 40)] / 2
x = [-2 ± √(-36)] / 2
x = [-2 ± -6i] / 2
x = -1 ± 3i
x = -1 + 3i OR x = -1 - 3i
Hence, the solution is x = -1 + 3i OR x = -1 - 3i

If you work for an airline need to sit a passenger every 30 seconds. If the doors open at 9:35 am, what time does the last passenger sit if there are 110?
Answer: 10:30 am
Step-by-step explanation: If you need to seat a passenger every 30 seconds, (half of a minute, which is 60 seconds), for every minute, 2 passengers will be seated. So, if you seat 2 passengers for a min each until you have seated 110 people, you will have taken up 55 minutes in total. (110 divided by 2 passengers a min). And finally, 55 minutes past 9:35 am would be 10:30 am. Hope this helps!

if molly needs to cross a river 16 feet wide how long does she have to walk
Molly has to walk for 16/x minutes where x is the speed of molly.
What is the speed of an object?Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time
Given here molly needs to cross a river 16 feet then let her speed be x and t be the time taken to cross the river
Then we have x=16/t
t=16/x
Hence, Molly has to walk for 16/x minutes where x is the speed of molly.

How much fencing is required to enclose a circular garden whose radius is 14m? Use 22/7 for π.
Answer:
The fencing required to enclose a circular garden whose radius is 22m is 138.16m
Answer:
[tex]\boxed {\boxed {\sf 88 \ meters}}[/tex]
Step-by-step explanation:
We want to find the amount of fencing required to enclose the garden. The fencing goes around the garden, which is a circle. Essentially, we are finding the perimeter or circumference of the circle.
The formula for circumference is:
[tex]c=\pi \times d[/tex]
We are given the radius, so we need to find the diameter. The radius goes from the center to the edge of the circle, while the diameter goes from edge to edge through the center. So, the diameter is twice the radius of 14 meters.
d=2 ×r d= 2 × 14 m d= 28 mNow we know the diameter is 28 meters. We also know 22/7 is being used for pi. Substitute these values into the formula.
[tex]c= \frac{22}{7} \times 28 \ m[/tex]
[tex]c=88 \ m[/tex]
The circumference is 88 meters, so 88 meters of fencing is requires to enclose the garden.

To accomplish this, the professor randomly selected 50 students from the university. It was found that the distribution was right skewed and unimodal. The sample mean was 11 hours with a sample standard deviation of 3. The professor then did a hypothesis test. Please find the test statistic for this hypothesis test Group of answer choices
Answer:
2.3574
Step-by-step explanation:
This question requires us to find the t test statistic given the data in the question.
H0: u = 10
H1: u > 10
Population variance is not known
T = (barX - u)/(s/√n)
u = 10 hours
BarX = 11 hours
Sd = 3 hours
n = 50
(11-10)/(3/√50)
t test = 1/(3/√50)
= 1/0.4242

On solving the question, 5 topping would pay the same amount for Pizza A and Pizza B, the value of equation 0.50x=2.50=> x=5
What is equation?An equation is a mathematical formula that connects two assertions using the equal sign (=) to denote equivalence. In algebra, an equation is a mathematical statement that establishes the equivalence of two mathematical expressions. For instance, an equal sign separates the components 3x + 5 and 14 in the equation 3x + 5 = 14. A mathematical formula is used to explain the connection between two sentences on either side of a letter. Frequently, there is just one variable, which is also the symbol. for example, 2x - 4 = 2.
let x be the number of toppings,the total cost of a pizza is given by:
pizza cost+topping cost
for pizza a =10+1.50x
for pizza b=12.50+1.00x
we solve for when cost are same and for how many toppings
10+1.50x=12.50+1.00x
10+0.50x=12.50
0.50x=2.50
x=5
