A waitress works 1.75 hours less in the afternoon than in the evening. If she works 5
1/8hours in the afternoon, how many hours does she work in the evening?
Answer:
She worked [tex]6\frac{7}{8}[/tex] hours in evening.
Step-by-step explanation:
Suppose, x be the hours waitress worked in evening,
Given,
She works 1.75 hours less in the afternoon than in the evening.
Thus, the number of hours she worked in afternoon = x - 1.75,
According to the question,
[tex]x-1.75 = 5\frac{1}{8}[/tex]
[tex]x-\frac{175}{100}=\frac{41}{8}[/tex]
[tex]x-\frac{7}{4}=\frac{41}{8}[/tex]
[tex]x=\frac{41}{8}+\frac{7}{4}[/tex]
[tex]x=\frac{41+14}{8}[/tex]
[tex]x=\frac{55}{8}=6\frac{7}{8}[/tex]
Therefore, she worked [tex]6\frac{7}{8}[/tex] hours in evening.

if a tree diagram were drawn to determine the number of possible outcomes when choosing one of 5 salads, one of 6 entrees, and one of 9 desserts, how many leaves would there be?
Answer:
270
Step-by-step explanation:
Just multiply.
5*6*9=270
Answer: There would be 270 leaves of a tree diagram.
Step-by-step explanation:
Since we have given that
Number of salads = 5
Number of entrees = 6
Number of desserts = 9
If we draw a tree diagram, we need to find the number of leaves there would be :
So, the number of leaves there would be is given by
[tex]5\times 6\times 9\\\\=270[/tex]
Hence, there would be 270 leaves of a tree diagram.
To the nearest tenth, what is the area of the shaded segment when AG = 6 ft?
10.3 ft2
21.1 ft2
1.7 ft2
28.3 ft2
Answer:
Option A is correct.
Step-by-step explanation:
Given:
AG = 6 ft ⇒ Radius of the circle , r = 6 ft
⇒ GB = AG = 6 ft
To find: Area of shaded Segment.
Area of Shaded Segment = Area of Sector AGBA - Area of Δ AGB
Sector AGBA forming 90° angle at center. [tex]\implies\,\theta=90^{\circ}[/tex]
Area of Sector = [tex]\frac{\theta}{360}\times\pi r^2[/tex]
Area of Sector AGBA = [tex]\frac{90}{360}\times3.14\times6^2[/tex]
= [tex]\frac{1}{4}\times3.14\times36[/tex]
= [tex]28.26\:ft^2[/tex]
ΔAGB is a right angled triangle.
So, Area of ΔAGB = [tex]\frac{1}{2}\times AG\times GB[/tex]
= [tex]\frac{1}{2}\times6\times6[/tex]
= [tex]6\times3[/tex]
= [tex]18\:ft^2[/tex]
Area of Shaded Segment = 28.26 - 18 = 10.26 ≈ 10.3 ft²
Therefore, Option A is correct.

A rectangle that has an area of 357 square inches is 17 inches wide. Using the formula for area (A=lw), how long is the rectangle? a. 21 inches b. 340 inches c. 20 inches d. 15 inches
Answer:
a - 21 inches
Step-by-step explanation:
Following the formula [tex]Area = l*w[/tex], we can find the length of the rectangle by plugging in values into the formula, then solving for [tex]l[/tex].
[tex]357=l*17[/tex]
[tex]\frac{357}{17} =\frac{l*17}{17} \\\\21=l\\l=21[/tex]

If you want to put a 4x8 piece of plywood through a 3-foot square opening in your ceiling by turning it diagonally, is the opening big enough? Use 45-45-90 triangle since it is a square
The first step is to calculate the length of the diagonal of the square opening.
The length of a diagonal of square = [tex] \sqrt{2} [/tex] * side
Given side = 3 feet
Length of the square hole = [tex] \sqrt{2} [/tex] *3 = 4.24 feet
since the diagonal is 4.24 feet and the shorter side of the plywood piece is only 4 feet, we can slide it through the square hole diagonally
Answer is YES since the diagonal 4.24 feet is greater than the shorter side of the plywood piece *4 feet

Assuming a truck container holds 24 cases, how many cases would 6 truck containers hold?
Answer:
6 truck containers can hold 144 cases
Step-by-step explanation:
A truck container holds 24 cases and we have to find number of cases would 6 truck container will hold.
We will solve this question by unitary method.
∵ One truck container holds cases = 24
∴ 6 truck containers will hold cases = 24×6 = 144
Therefore 144 cases is the answer.

When is periodic data useful? Give examples to support your answer.
Periodic data is useful for analyzing trends over time, helping to forecast future events, and measure frequencies of occurrences. It is applicable in various fields including business, environmental science, and health for planning strategies and understanding patterns.
Periodic data is useful when we are interested in analyzing and understanding trends over regular intervals of time. It helps us to observe patterns and forecast future occurrences based on historical information. For example, in business, we may look at quarterly sales figures to identify seasonal effects on sales and plan inventory accordingly. In environmental science, climate data recorded over decades can be critical for studying changes in weather patterns and predicting future climate events. In health, collecting epidemiological data periodically can enable public health officials to track the spread of diseases and the effectiveness of interventions.
Frequency, relative frequency, and cumulative relative frequency are measures that can describe how often certain events occur within periodic data. These measures help answer questions like 'How many students study five hours or more for an exam?' or 'What percent of families own two pets?' They are crucial for understanding the distribution of data and for making informed decisions based on that data.
10,14 and 18 can someone answer Pls pls
Answer:
10) 35
14) x = 1/2
18) 10 cm
Explanation:
For question 10, we can set up a proportional equation, cross-multiply and solve for the missing number:
[tex]\frac{x}{14} = \frac{5}{2}[/tex]
2x = 14(5)
2x = 70
2x / 2 = 70 / 2
x = 35
The missing number is 35
For question 14, we isolate variables on one side of the equation and constants on the other by performing whatever operations are necessary and then solve for the variable:
14x + 2 = 9
14x + 2 - 2 = 9 - 2
14x + 0 = 7
14x = 7
14x / 14 = 7 / 14
x = 7 / 14
x = 1/2
x = [tex]\frac{1}{2}[/tex]
For question 18, there are 10 millimeters (mm) in 1 centimeter (cm) so we can use this relationship so set up a conversion factor and cross-multiply to find the missing value like we did in question 10:
[tex]\frac{10}{1} = \frac{100}{x}[/tex]
10x = 100(1)
10x = 100
10x / 10 = 100 / 10
x = 10
There are 10 cm in 100 mm.
