Answer: 400 seconds
Step-by-step explanation:
5x = 400 + y
4x = y
take 4x and add it to the top so it looks like this:
5x = 400 + 4x
cancel 4x if you don't know how to do it you do it like this you take +4x and instead you do -4x to cancel.
and you do it to 5x so you cancel 4x and 5x - 4x = x so x = 400
x = 400

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.

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.
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.

LCD is 5, multiply 5 with each term. the equation becomes
[tex]\frac{2}{5} \cdot 5+p \cdot 5= \frac{4}{5} \cdot 5 +\frac{3}{5}p \cdot 5[/tex]
[tex]2+5p = 4 +3p[/tex]
Subtract 3p from both sides
[tex]2+2p = 4[/tex]
Subtract 2 on both sides
[tex]2p= 2[/tex]
Divide by 2 on both sides
p= 1
So the value of p =1 for the given equation
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 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

F. (21/7)^x
After simplifying the original expression, the equivalent expressions to [tex]21^x/7x[/tex] are C. [tex]3^x[/tex] and F. [tex](21/7)^x.[/tex]
Explanation:The original expression in the question is [tex]21^x/7x[/tex]. To find equivalent expressions, we first simplify the original expression. The expression [tex]21^x[/tex]is the same as [tex](7*3)^x,[/tex] which, by property of exponents, can be written as [tex]7^x * 3^x.[/tex]Then, given the expression is divided by 7x, the x in the denominator cancels out with the x from [tex]7^x.[/tex] Hence, the simplified form will be [tex]3^x.[/tex] Now, we compare it with the given options.
Option C is directly equal to the simplified form. While options A,D, E, and B are not equivalent to the original expression. Considering option F, 21/7 simplifies to 3 and so, [tex](21/7)^x[/tex] can be rewritten as [tex]3^x[/tex] which is equal to the simplified form. Therefore, the equivalent expressions are C. [tex]3^x[/tex]and F. [tex](21/7)^x.[/tex]

The equivalent expressions to [tex]21^x/7x[/tex] are 3^x and [tex]7^x * 3^x/ 7^x[/tex], and[tex](21/7)^x,[/tex]which can all be simplified to result in 3^x.
Explanation:The expressions equivalent to 21^x/7x are checked by determining if they simplify down to the same value as the original expression. Taking the original expression 21^x/7x, it's clear that 21 can be rewritten as 7*p, so 21^x/7x simplifies to [tex](7*3)^x/7x = 7^x*3^x/7x = 3^x[/tex] (because [tex]7^x/7^x = 1).[/tex]
From the given options, Option C: 3^x, and Option E: [tex]7^x * 3^x/ 7^x[/tex]satisfy this criterion, as they also simplify to 3^x. Option F: (21/7)^x also simplifies as explained earlier to 3^x. So, options C, E, and F are equivalent to the original expression.

Determine whether the given coordinates are the vertices of a triangle. Explain.
L(–24, –19), M(–22 ,20), N(–5, –7)
A:
yes:
LM + MN > LN,
LM + LN > MN,
LN + MN > LM
B:
no:
LM + MN = LN
C:
no:
LM + MN < LN
D:
yes:
LM + MN < LN,
LM + LN < MN,
LN + MN < LM
Final answer:
After computing the distances between the points L, M, and N using the distance formula and comparing them, it is clear that the sum of the lengths of any two sides is greater than the length of the third side, satisfying the conditions of a triangle.
Explanation:
To determine whether the given coordinates are the vertices of a triangle, we can check if the sum of the lengths of any two sides is greater than the length of the third side, which is a principle derived from the triangular inequality theorem. First, we calculate the distances between the points L(–24, –19), M(–22, 20), and N(–5, –7) using the distance formula: √((x2-x1)² + (y2-y1)²).
For LM: √((-22 + 24)² + (20 + 19)²) = √(4 + 1521) = √(1525)
For MN: √((-5 + 22)² + (-7 - 20)²) = √(289 + 729) = √(1018)
For LN: √((-5 + 24)² + (-7 + 19)²) = √(361 + 144) = √(505)
Now we compare the lengths:
LM + MN > LN
LM + LN > MN
LN + MN > LM
Since all three conditions are satisfied, the points L, M, and N form a triangle.
