a total of $689 tickets were so far School play they were either adult tickets or student tickets there were 61 fewer students tickets so then adult tickets how many adult tickets were sold
Answer:
375 adult tickets314 student ticketsStep-by-step explanation:
You want to know the number of adult ticket sold if there were 61 fewer student tickets sold and the total number sold was 689.
SetupLet a = the number of adult tickets sold. Then a-61 is the number of student tickets sold, and the total is ...
a + (a -61) = 689
SolutionSimplifying, we get
2a -61 = 689
2a = 750 . . . . . . add 61
a = 375 . . . . . . . divide by 2
The number of adult tickets sold was 375.
__
Additional comment
The number of student tickets is 375-61 = 314.

Need the answer!!!!!
Answer:
k = {- 6.5; 5}=====================================
Solution in steps:
-5 |3 + 4k| = -115 Given|3 + 4k| = - 115/ - 5 Divide both sides by - 5|3 + 4k| = 23 Open absolute value 3 + 4k = 23 and 3 + 4k = - 23 Two scenarios, subtract 3 from both sides4k = 20 and 4k = - 26 Simplifyk = 20/4 and k = -26/4 Divide by 4k = 5 and k = - 6.5 AnswerAnswer:
k = 5 (or) k = -6.5
Step-by-step explanation:
Given equation,
→ -5|3 + 4k| = -115
Then the value of k will be,
→ -5|3 + 4k| = -115
→ |3 + 4k| = -115/-5
→ 3 + 4k = 23 || → 3 + 4k = -23
→ 4k = 23 - 3 || → 4k = -23 - 3
→ k = 20/4 || → k = -26/4
→ [ k = 5 ] || → [ k = -6.5 ]
Hence, values are 5 and -6.5.

Option b. is correct.
A standard deviation (or σ) is a proportion of how distributed the information is comparable to the mean. A low standard deviation implies information is grouped around the mean, and an elevated requirement deviation demonstrates information is more fanned out.
The standard deviation of a population or sample and the standard error of measurement (e.g., of the example mean) is very unique however related. The example implies the standard error is the standard deviation of the arrangement of implies that would be found by drawing an endless number of samples from the population and registering a mean for each sample.

Six customers are buying gasoline at Miguel's Gasoline Station. The number of gallons bought and the total cost of their purchases are plotted on the graph below.
What is the price per gallon at Miguel's Gasoline Station?
Responses
$2.50
Based on the line on the graph, the price per gallon at Miguel's Gasoline Station is equal to: B. $2.50
How to calculate the price per gallon?In order to calculate the price per gallon at Miguel's Gasoline Station, we would have to determine the slope of the line representing the number of gallons bought and the total cost of their purchases are plotted on the graph below (see attachment).
Mathematically, the slope of any straight line can be calculated by using this formula;
Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)
Slope, m = (y₂ - y₁)/(x₂ - x₁)
By critically observing the graph (see attachment), we can logically deduce that the line passes through the following points:
Points (x, y) = (4, 10)Points (x, y) = (8, 20)Substituting the given parameters into the formula, we have;
Slope, m = (20 - 10)/(8 - 4)

A gallon of water contain 128 fluid ounce. A rain barrel can hold 6,400 ounce of rainwater. Etimate how many gallon of water can the barrel hold?
If a gallon of water contain 128 fluid ounce and a rain barrel can hold 6,400 ounce of rainwater, then the number of gallons of water that can the barrel hold is 50 gallons
A gallon of water in ounce = 128 ounce
Number of ounce of water that rain barrel can hold = 6400 ounce
To find the number of gallon of water we have to apply division
number of gallons of water that can the barrel hold = Number of ounce of water that rain barrel can hold / A gallon of water in ounce
= 6400 / 128
= 50 gallons
Hence, if a gallon of water contain 128 fluid ounce and a rain barrel can hold 6,400 ounce of rainwater, then the number of gallons of water that can the barrel hold is 50 gallons

Given that,
A automobile model is 3 feet long and 1 foot wide. Considering that the automobile is 15 feet long
To find : The width of the actual car
Model Car's Width (W) = 1 foot
Model Car's Length (L) = 3 feet
Actual Car's Length (l) = 15 feet
Actual Car's Width (w) = x feet
To solve,
We know that,
Product of Means = Product of Extremes which means ,

In this figure, AB¯¯¯¯¯¯¯¯∥CD¯¯¯¯¯¯¯¯ and m∠2 = 61°.
What is m∠6?
Answer:
m∠6 = 61°
Step-by-step explanation:
Given a transversal crossing parallel lines AB and CD, you want the measure of angle 6 given that angle 2 is 61°.
Angles at a transversalWhere a transversal crosses parallel lines, corresponding angles and vertical angles are congruent. This has the effect of making all acute angles congruent, and all obtuse angles congruent.
Acute angle 6 is congruent to acute angle 2, which measures 61°. (They are "corresponding" angles.)
m∠6 = 61°

They are congruent by SAS as follows if I understand you correctly:
Since x is shared by both NR and AG, it must be at their intersection.
Because it lies in the middle of both, NX = XR and AX = XG.
We join point A to point N and point R to point G to complete the triangles (any 2 points define a line).
Due to the fact that there are two triangles on either side of the point X, angle AXN is perpendicular to angle RXG. Angle AXN is equal to angle RXG because the vertical (opposite) angles formed by two intersecting lines are equal.
The following is how the SAS evidence of congruency is established:
Angle RXG in triangle RXG and angle AXN in triangle AXN are congruent (vertical angles)
Triangles AX in AXN and XG in RXG are congruent (midpoint X of line AG created these).
Triangle RXG and triangle AXN's NX and XR are congruent.

How to Interpret the Velocity Time Graph?
The velocity time graph for a cycle is as attached.
The distance covered will be the area under the curve.
Formula for area of trapezium is;
A = (1/2)(sum of parallel sides) * height
Area for 0 to 14 sec is a trapezium formed with parallel sides as 14 and 10 while distance between them is 8 is solved as;
Area = (1/2)(14 + 10) * 8
Area = 24 * 4 = 96
Thus;
Distance covered = 96 m
Distance travelled on the cycle in the first 14 seconds is 96 m.
