In a party, the guest's attendance depends on their vehicle status. If they have four wheelers then the attendance of guests is 2500 and if they have two wheelers then the attendance of guests is 1500. If on the next party, 70% of families will have four wheelers and 30% of families will have two wheelers. What is the expected attendance of guests?
Answers
When 70% of families will have four-wheelers and 30% of families will have two-wheelers, the projected guest attendance is 3000+1200 = 4200.
what is percentage ?In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100. Occasionally, the acronyms "pct.," "pct," and "pc" are also used. But it is commonly indicated by the percent sign, "%." The % amount has no dimensions. Percentages are essentially fractions when the denominator is 100. Use the percent sign (%) to indicate that a number is a percentage by placing it next to it. For instance, you score a 75% if you properly answer 75 out of 100 questions on a test (75/100). Divide the money by the total and multiply the result by 100 to calculate percentages. The formula for calculating the percentage is (value/total) x 100%.
given
2500 guests are present when four-wheelers are available.
two wheelers, the number of guests is 1500,
making the total 2500 + 1500 = 4000.
70 percent of families will own four-wheelers, or 3000/4000/100.
30% of families will own two-wheelers, which equals 4000/100 * 30%, or 1200.
When 70% of families will have four-wheelers and 30% of families will have two-wheelers, the projected guest attendance is 3000+1200 = 4200.

Find an equation for the line that passes through the points (-5, 2) and (3, 4)
Answers
Step-by-step explanation:
1. Find the slope first using y2 - y1/ x2 - x1. This should look like 4 -2/ 3 - (-5), which can also be written as 4 - 2/ 3 + 5.
2. Simplify the fraction. This should look like 2/8, which can also be written as 1/4 once you divide it by 2.
3. Use the point-slope formula to find the y-intercept of the equation now. The formula is y2 - y1 = m (x2 - x1). Input either (-5, 2) or (3,4) into the equation. I'll use (3,4) as an example. After inputting that point, the equation would be y - 4 = 1/4 (x - 3).
4. Simplify this equation by distributing the 1/4 into the parentheses first. Once done, the equation will be y - 4 = 1/4x - 0.75.
5. Add 4 on both sides of the equation to get y by itself. After that the equation will be y = 1/4x + 3.25.

What is sine rule?Law of Sines In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.
The formula for sine rule is sinA/a=sinB/b=sinC/c
Given that, an interior designer plans to use triangular tiles that are 8 cm×9 cm×13 cm for a backsplash.
Using cosine rule, we get
9²= 8²+ 13²- 2(8)(13) cos θ (angle opposite 9 cm side.)
81=64+169-208 cos θ
81-233=-208 cos θ
-208 cos θ=-152
cos θ=-152/(-208)
cos θ=0.7307
θ=43.7°
Using sine rule,
The formula for sine rule is sinA/a=sinB/b=sinC/c
sinA/8 =sin43°/9=sinC/13
sinA/8 =0.7307/9
sinA/8=0.0811
sinA=0.6495
A=40.5°
So, ∠A+∠B+∠C=180°
40.5°+43.7°+∠C=180°
∠C=95.8°
Therefore, the measures of three angles are 40.5°, 43.5° and 95.8°.

what is an equation of the line that passes through point (-6,-5) and is parallel to the line x + 5y=25
Answers
Answer:
y = -1/5x - 31/5
Step-by-step explanation:
If two lines are parallel to each other, they have the same slope.
The first line is x + 5y = 25.
First, let's put this in standard form of y = mx + b.
x + 5y = 25
Subtract x from both sides.
5y = -x + 25
Divide each term by 5.
y = -1/5x + 5
This line's slope is -1/5. A line parallel to this one will also have a slope of -1/5.
Plug this value (-1/5) into your standard point-slope equation of y = mx + b.
y = -1/5x + b
To find b, we want to plug in a value that we know is on this line: in this case, it is (-6, -5). Plug in the x and y values into the x and y of the standard equation.
-5 = -1/5(-6) + b
To find b, multiply the slope and the input of x (-6)
-5 = 6/5 + b
Now, subtract 6/5 from both sides to isolate b.
-5 - 6/5 = b
-25/5 - 6/5 = b
-31/5 = b
Plug this into your standard equation.
y = -1/5x - 31/5
This equation is parallel to your given equation (y = -1/5x + 5) and contains point (-6, -5)
Hope this helps!
