Answer:
350 adult tickets were sold.
Step-by-step explanation:
Let's set up some values:
x = adult tickets
x + 50 = student tickets, since there were 50 more student tickets than adult tickets.
Now, let's set up our equation. If these two values add up to 750 tickets, then we can conclude the following:
(x) + (x + 50) = 750
2x + 50 = 750
2x = 700
x = 350 adult tickets. This means there were 400 student tickets sold.

Answer:

Step-by-step explanation:
The variable S represents the height off the ground, so we can substitute in the value 140 for it:
[tex]140 = 80t - 5t^{2}[/tex]
We can add [tex]5t^{2}[/tex] to both sides and subtract [tex]80t[/tex] so the equation is in standard form:
[tex]5t^{2} - 80t + 140 = 0[/tex]
Every term has five as a factor, so we may divide both sides of the equation by 5.
[tex]t^{2} - 16t + 28 =0[/tex]
To factor this, we need two numbers that multiply to 28 and sum to -16. These numbers are -14 and -2, so these are the two factors:
[tex](t-14)(t-2)=0[/tex]
We can see that when t = 14 or 2, the whole left has a value of zero, so they are the two answers.
We are asked when the rocket first is at 140m, and 2 seconds is before 14, so the answer is 2 seconds.
rounding to the nearest hundredth percent. if the cost of an item is $16.90 the selling price is $25.60. The dollar markup is $8.70. what is the percent markup on cost ?
the selling price is 25.60, the cost was 16.9, that means 25.6 - 16.9 = 8.7, so the item's price has been bumped up by 8.7 bucks, which is the markup, how much is that of 25.6?
worded differently, if we take 16.9(cost) to be the 100%, what is 8.7 off of it in percentage?
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 16.9 & 100\\ 8.7& x \end{array} \implies \cfrac{16.9}{8.7}~~=~~\cfrac{100}{x} \\\\\\ 16.9x=870\implies x=\cfrac{870}{16.9}\implies x\approx 51.48[/tex]

f (x) =-3x+25; Find f(x)=52
Simplifying
-3x + 25 = 52
Reorder the terms:
25 + -3x = 52
Solving
25 + -3x = 52
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-25' to each side of the equation.
25 + -25 + -3x = 52 + -25
Combine like terms: 25 + -25 = 0
0 + -3x = 52 + -25
-3x = 52 + -25
Combine like terms: 52 + -25 = 27
-3x = 27
Divide each side by '-3'.
x = -9
Simplifying
x = -9

5. Brandon and Chloe ride their bikes for 4 hours along a flat, straight road. Brandon’s velocity, in miles per
hour, at time t hours is given by a differentiable function B for 0 st 54. Values of B(t) for selected times t
are given in the table above. Chloe's velocity, in miles per hour, at time t hours is given by the piecewise
function C defined by

for 0
12 – 3t – 12 for 2 <154.
(a) How many miles did Chloe travel from time t = 0 to time t = 2 ?
Do not write beyond this border.
Do not write beyond this border.
Answer:
Step-by-step explanation:
a) ∫from 0 to 2 of te^(4-t^2) dt. Let u = 4-t^2. du= -2dt. And, tdt= -dy/2.
If x=0, u= 4 and if x=2, u=0.
Therefore our new integral will be, -(1/2) ∫ from 0 to 4 of e^u du.
= -(1/2)(e^u) | 0 to 4
= -(1/2)(e^0 - e^4)
= -(1/2) + (1/2)e^4
= (1/2)(e^4 -1) miles
Therefore, from t=0 to t=2, Chloe has travelled a distance of (1/2)(e^4-1) miles.
b) At t=3, C(t)=12-3t-t^2
C(t) is already a function of velocity so simply plug in C(3), which is -6 miles/hour.
We also need to know acceleration.
C'(t)= -3 - 2t
C(3)= - 9 miles/hour squared.
Therefore, since velocity and acceleration are both negative, Chloes speed is increasing at t =3 hours.

An uber driver charges a flat fee of $6.00 and $1.50 per mile, which equation can be used to find the total cost of a ride from the uber driver? Group of answer choices C=(1.5+6)m m=1.5C+6 C=6m+1.5 C=1.5m+6
Answer:
C = 1.5m+6
Step-by-step explanation:
The numbers of miles that we ride, we are charged 1.5 based on that. Hence, 1.5m. And we are anyway charged with 6 dollars, so plus 6.

A (16p.7p) + 53p
B (53p • 16p): 7p
C (16p + 7p): 53p
D (53p + 16p) + 7p
The expression 53p + (16p+7p) is equivalent to expression (53p + 16p) + 7p
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 53p + (16p + 7p)
Fifty three times of p plus sixteen p plus seven p.
In the given expression p is the variable and plus is the operator.
We need to find the equivalent expression.
Equivalent expressions are expressions that work the same even though they look different.
53p + (16p + 7p)
76p
(53p + 16p) + 7p is also equal to 76p

At a tournament, the bowling league is providing 160 sandwiches for its members. The table shows the number of different types of sandwiches that were ordered. The ratio of turkey sandwiches to roast beef sandwiches is 5:3. Drag the numbers to complete the table.
Answer: See below
Step-by-step explanation:
The total number of ordered sandwiches is 160
The total number of Turkey Sandwiches is 80
The ratio of Turkey to Roast Beef is 5:3
So from this, 5 times of a value is 80
So 5x = 80
And x = 16
So the Roast beef sandwiches are 16×3=48
Therefore, the table is:
Sandwich type Number
Turkey 80
Roast Beef 48
Vegetarian 32

Is 5 inches bigger than 1/3 if a foot
Answer:
Yes
Step-by-step explanation:
1 foot= 12 inches
12÷3=4
This means that 1/3 of a foot is 4 inches
5 inches is larger than 4 inches
Answer:
Yes
Step-by-step explanation:
1/3 is 0.33333333333333 foot which = 4 inches.
Formula: multiply the value in feet by the conversion factor '12'.
So, 0.33333333333333 foot = 0.33333333333333 × 12 = 4 inches.
The other value is 5 inches.
5 inches is greater than 4 inches.
