The lengths of the triangle's sides are 5, 12, and 13. What is the measure of the angle opposite to side 13?
Answer:
90°
Step-by-step explanation:
5, 12 and 13 are the sides of a right triangle ( Pythagorean triple )
13 is the measure of the hypotenuse whose opposite angle is 90°
Answer:
90°
Step-by-step explanation:
5^2+ 12^2 = 13^2
25 + 144 = 169
The Converse Pythagorean Theorem (Egyptian triangle) states that if the length of the sides of a triangle, say a, b, and c, satisfy a^2 + b^2 = c^2, then this is a right triangle with a right angle opposite to side c.
And since 5^2 + 12^2 = 13^2 satisfies the statement a^2 + b^2 = c^2, c (which is 13) is opposite to a 90° angle.

Jada has p pennies and n nickels that add up to more than 40 cents. She had fewer than 20 coins altogether. Write a system of inequalities that represent how many pennies and nickels that jada could have.
Answer:
5n+p>40
n+p<20
Step-by-step explanation:
Since pennies are worth 1 cent and nickels 5, using n as the number of nickels and p as the number of pennies, we can say that 5*n+1*p>40. Then, n+p is less than 20, so n+p<20. Our answer is then
5n+p>40
n+p<20
The currency called the dollar can be split into smaller forms called nickels, pennies, dimes, and quarters.
The system of inequalities that represents how many pennies and nickels that Jada could have is given as:
p + n < 200.01p + 0.05n > 0.40Let's represent the number of :
pennies = p
nickels = n
It is important to also note that:
1 penny = $0.01
1 nickel = $0.05
40 cents can also be written as: $0.40
Jada has p pennies and n nickels that add up to more than 40 cents.
The word more than means greater than and this can be represented by the inequality sign ">". Hence, our inequality equation is given as:
$0.01 x p + $0.05 x n > $0.40
0.01p + 0.05n > 0.40
She had fewer than 20 coins altogether.
The word fewer means less than and this can be represented by the inequality sign "<". Hence, our inequality equation is given as:
p + n < 20
Therefore, the system of inequalities that represents how many pennies and nickels that Jada could have is given as:
p + n < 200.01p + 0.05n > 0.40To learn more, visit the link:

would it be cheaper to rent the buses or the vans? why?
~~~~~~~~~~~~
please get this finished soon, it's due homework for tomorrow.
whilst this is being answered, I'm going to be doing other homework, so good luck answering this one
It would take 13 buses to get everyone to the zoo
It would take 26 vans to get everyone to the zoo
It would be cheaper to rent buses
Step-by-step explanation:
The given is:
A school is taking 388 students on a field trip to the zooThey can rent buses that hold 30 students for $895 eachThey can rent vans that hold 15 students for $450 eachWe need to find how many buses it would take to get everyone to the zoo, how many vans it would take to get everyone to the zoo, and would it be cheaper to rent
∵ The number of students is 388
∵ Each bus can hold 30 students
- Divide the number of students by 30 to find the number of buses
∴ The number of buses = 388 ÷ 30 = 12.92
- They must to rent 13 bus to hold all the students
∴ The number of buses is 13
It would take 13 buses to get everyone to the zoo
∵ The number of students is 388
∵ Each van can hold 15 students
- Divide the number of students by 15 to find the number of vans
∴ The number of vans = 388 ÷ 15 = 25.87
- They must to rent 26 vans to hold all the students
∴ The number of vans is 26
It would take 26 vans to get everyone to the zoo
Let us find the cost of rent of the buses and vans to find which of them is cheaper
∵ The cost of rent of each bus = $895
∵ The number of buses = 13
∴ The cost of rent the buses = 13 × 895 = $11635
∵ The cost of rent of each van = $450
∵ The number of vans = 26
∴ The cost of rent the buses = 26 × 450 = $11700
∵ $11635 < $11700
∴ The cost of rent the buses < the cost of rent the vans
∴ The buses is cheaper than the vans
It would be cheaper to rent buses

What is 28 is 35% of what number
Answer:
80
Step-by-step explanation:
35/100X = 28
35X = 2800
2800/35=80
Answer: 80
Step-by-step explanation: To answer the question 28 is 35% off what number, we translate the question into an equation.
So we have "28 is" which means 28 = 35% which we need to write as a decimal. To write a percent as a decimal, we move the decimal point 2 places to the left so 35% can be written as the decimal .35. Next we have "of what number" which means times X.
Now we have the following equation.
28 = (.35) (x)
Now to solve for x since x is being multiplied by .35, we need to divide by .35 on both sides of the equation.
On the right side of the equation, the .35's cancel and we have x. On the left side of the equation, we have 28 ÷ .35 which is 80.
So 80 = x.
Therefore, 28 is 35% of 80.

A 6000-seat theater has tickets for sale at $28 and $40. How many tickets should be sold at each price for a sellout performance to generate a total revenue of $189600?
Answer:
4200 tickets of [tex]\$28[/tex] and 1800 tickets of [tex]\$40[/tex] were sold
Step-by-step explanation:
Given:
Tickets are sold at price [tex]\$28[/tex] and [tex]\$40[/tex].
Let Number of tickets sold at price [tex]\$28[/tex] be [tex]x[/tex].
Let Number of tickets sold at price [tex]\$40[/tex] be [tex]y[/tex].
Theater has maximum capacity of 6000 seat.
Hence,
[tex]x+y=6000 \ \ \ \ equation \ 1[/tex]
Total revenue to be generated is [tex]\$189600[/tex]
[tex]\therefore 28x + 40y= 189600 \ \ \ \ equation \ 2[/tex]
Now Multiplying equation 1 by 40 we get,
[tex]x+y=6000\\40x+40y=240000\ \ \ \ equation \ 3[/tex]
Now Subtracting equation 2 by equation 3 we get,
[tex](40x+40y=240000)- (28x + 40y= 189600)\\12x=50400\\\\x=\frac{50400}{12}=4200[/tex]
Now substituting value of x in equation 1 we get,
[tex]x+y=6000\\4200+y=6000\\y=6000-4200= 1200[/tex]
Hence a total of 4200 tickets of [tex]\$28[/tex] and 1800 tickets of [tex]\$40[/tex] were sold
To generate a total revenue of $189,600, 4200 tickets should be sold at $28 and 1800 tickets should be sold at $40.
Explanation:To find the number of tickets to be sold at each price, we can set up a system of equations. Let's assign variables:
Let x be the number of tickets sold at $28.
Let y be the number of tickets sold at $40.
The total revenue from selling x tickets at $28 is 28x, and the total revenue from selling y tickets at $40 is 40y. Since the total revenue is $189,600, we can write the equation:
28x + 40y = 189,600
We also know that the total number of tickets sold is x + y = 6000.
We can solve this system of equations to find the values of x and y. One way is to multiply the second equation by 28 and subtract it from the first equation:
28x + 40y - 28x - 28y = 189,600 - 28(6000)
12y = 189,600 - 168,000
12y = 21,600
y = 21,600 / 12 = 1800
Substituting the value of y in the equation x + y = 6000, we get:
x + 1800 = 6000
x = 6000 - 1800 = 4200
Therefore, 4200 tickets should be sold at $28 and 1800 tickets should be sold at $40 to generate a total revenue of $189,600.

If [tex]a^{n}=a^{m}[/tex] , then n = m[tex](a^{n})^{m}=a^{nm}[/tex]∵ [tex]9^{(x+15)}=3^{7x}[/tex]
∵ 9 = 3 × 3
∴ 9 = 3²
- Substitute 9 by 3² in the equation above

- Use the second rule above for the left hand side
∵ [tex](3^{2})^{(x+15)}=3^{2(x+15)}[/tex]
∴ [tex](3^{2})^{(x+15)}=3^{2x+30}[/tex]
∴ [tex]3^{2x+30}=3^{7x}[/tex]
- By using the first rule above
∴ 2x + 30 = 7x

Indicate the equation of the line, in standard form, that passes through (2, -4) and has a slope of 3/5.
The equation of the line in standard form is 3x - 5y = 26
Step-by-step explanation:
Let us revise the forms of the linear equation
The slope intercept form is y = mx + b, where m is the slope of the line and b is the y-interceptThe point-slope form is [tex]y-y_{1}=m(x-x_{1})[/tex] , where m is the slope of the line and [tex](x_{1},y_{1})[/tex] is a point on the lineThe standard form is Ax + By = C, where A, B, and C are constantThe general form is Ax + By + C = 0, where A, B, and C are integers∵ The line passes through point (2 , -4)
∵ The slope of the line is [tex]\frac{3}{5}[/tex]
- Let us using the point-slope form and then change it to the
standard form
∵ [tex]x_{1}[/tex] = 2 and [tex]y_{1}[/tex] = -4
∵ m = [tex]\frac{3}{5}[/tex]
- Substitute these values in the form of the equation below
∵ [tex]y-y_{1}=m(x-x_{1})[/tex]
∴ [tex]y-(-4)=\frac{3}{5}(x - 2)[/tex]
∴ [tex]y+4=\frac{3}{5}(x - 2)[/tex]
Let us change it to standard form
- Multiply each side my 5 to cancel the denominator in the
right hand side
∴ 5(y) + 5(4) = 3(x - 2)
- Simplify the two sides
∴ 5y + 20 = 3x - 6
- Add 6 to both sides
∴ 5y + 26 = 3x
- Subtract 5y from both sides
∴ 26 = 3x - 5y
- Switch the two sides
∴ 3x - 5y = 26
The equation of the line in standard form is 3x - 5y = 26

The coin falls down with an average speed of 44.1 meters per second from 3 seconds to 6 seconds.

PLEASE HELP!!
The average rate of change of d(t) from t = 3 to t = 6 represent: A. The coin travels an average distance of 44.1 meters from 3 seconds to 6 seconds.
In Mathematics and Geometry, the average rate of change (ARoC) of a function f(x) on a closed interval [a, b] can be calculated by using this mathematical equation (formula):
Average rate of change (ARoC) = [tex]\frac{f(b) - f(a)}{(b - a)}[/tex]
Based on the given quadratic function, we can reasonably infer and logically deduce the following:
[tex]d(t)=4.9t^2\\\\d(3)=4.9(3)^2[/tex]
f(a) = d(3) = 44.1
[tex]d(t)=4.9t^2\\\\d(6)=4.9(6)^2[/tex]
f(a) = d(3) = 176.4
Next, we would determine the average rate of change (ARoC) of the function over the interval [3, 6]:
Average rate of change (ARoC) = [tex]\frac{176.4 - 44.1}{(6 - 3)}[/tex]
Average rate of change (ARoC) = 44.1 meters.
In this context, we can logically deduce that the coin travels an average distance of 44.1 meters from 3 seconds to 6 seconds.
Karen went to the farmers market
to buy a total of 17 papayas and pineapples. If papayas were 2.50 each, pineapples were $3
each and she spent a total of $48, how many of each fruit did she buy?!
Answer:
6 papayas and 11 pineapples
Step-by-step explanation:
So, we need to find an answer of how many papayas and pineapples she bought, and we only spent $48.
So, papayas are $2.50 each, and Pineapples are $3.00 each and we only bought 17 fruits total.
lets try 8 papayas, and 9 Pineapples.
$2.50 x 8 = $20.00 total on Papayas
$3.00 x 9 = $27.00 total on Pineapples.
That would only be $47 spent total.
Lets try 10 papayas and 7 pineapples.
$2.50 x 10 = $25.00
$3.00 x 7 = $21.00
That would only be a total of $26 spent.
Lets try 6 papayas and 11 pineapples.
$2.50 x 6 = $15.00
$3.00 x 11 = $33.00
This would be a total of $48 spent.

The crop yield decreased by 0.1 pounds per acre from year 10 to year 20.
Answer:
The average rate of change = -10
The crop yield decreased by 10 pounds per acre from year 10 to year 20.
Step-by-step explanation:
A farmer is tracking the number of soybeans his land is yielding each year. He finds that the function [tex]f(x) =-x^2 + 20x + 100[/tex] models the crops in pounds per acre over x years.
The average rate of change can be calculated using formula
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
In your case,
[tex]a=10\\ \\b=20,[/tex]
then
[tex]f(a)=-10^2+20\cdot 10+100=-100+200+100=200\\ \\f(b)=-20^2+20\cdot 20+100=-400+400+100=100[/tex]
and the average rate of change is
[tex]\dfrac{100-200}{20-10}=\dfrac{-100}{10}=-10[/tex]
This means the crop yield decreased by 10 pounds per acre (negative rate of change) from year 10 to year 20.
