Answer:
Step-by-step explanation:
the Pythagorean theorem is :
a^2+b^2=c^2
c is the hypotenuse
if y is the hypotenuse then x^2+z^2=y^2
if x is the hypotenuse then y^2+z^2=x^2
Which inequality has an open circle when it is graphed on a number line?
Answer:
See below
Step-by-step explanation:
If you consider an open circle, it would exclude the value with which we have circled when writing the inequality. Hence the only possible signs with in such an example can be a greater than sign ( > ) or less than sign ( < );
Let us take a look at an example to help. We are given a graph with an open circle on the number say 3. An arrow extends to the right of this number 3;
[tex]Inequality Sign - <,\\Inequality - x > 3,\\[/tex]

The concession stand at the high school football stadium sells hot dogs and sodas. Jack bought 3 hotdogs and 2 sodas for a total of $12. Angie bought 1 hotdog and 4 sodas for $9. Solve a system of equations to determine the cost of 1 hotdog and 1 soda.
Answer: each soda costs $1.5 and each hotdog costs $3.
Step-by-step explanation:
If H is the price for one hotdog and S is the price for one soda, we have the equations:
for Jack.
3*H + 2*S = $12
For Angie.
1*H + 4*S = $9
Now we can isolate one of the variables in one of the equations and then replace it in the other equation, let's isolate H in the second equation:
H = $9 - 4*S
now we replace it in the first eq
3*H + 2*S = $12
3*($9 - 4*S) + 2*S = $12
$27 - 12*S + 2*S = $12
-10*S = $12 - $27 = -$15
S = $15/10 = $1.5
Now we can replace it in the equation for H and get:
H = $9 - 4*$1.5 = $3
So each soda costs $1.5 and each hotdog costs $3.
Answer: One hotdog cost $3 and One soda costs $1.5
Step-by-step explanation:
Let hotdogs be denoted by h
Let sodas be denoted as s
Jack bought 3 hotdogs and 2 sodas for a total of $12. This can be written as:
3h + 2s = 12
Angie bought 1 hotdog and 4 sodas for $9. This can be written as:
h + 4s = 9
3h + 2s = 12
h + 4s = 9
1 × (3h + 2s = 12)
3 × (h + 4s = 9)
3h + 2s = 12
3h + 12s = 27
Subtract the equation
-10s = -15
s = -15/-10
s = 1.5
One soda cost $1.5
Since h + 4s = 9
h + 4(1.5) = 9
h = 9 - 6
h = 3
One hotdog costs $3
Find the areas of the trapezoids. PLZ HELP!!!!
Answer:
Type 7.5 in the box!
Step-by-step explanation:
Consider the trapezoid formula ( ( base 1 + base 2 ) / 2 ) * height;
[tex]Length of Base 1 - 1 unit,\\\\Length of Base 2 - 4 units,\\\\Length of Height - 3 units ( length of x - intercept in shaded region )\\\\Area of Trapezoid = ( Average of Bases ) * Height = ( ( 1 + 4 ) / 2 ) * 3 = ( 5 / 2 ) * 3 = 7.5 square units,\\\\Solution; 7.5 square units[/tex]
Area = 7.5 square units
The area of the trapezoid is 7.5 square units.
To Find the Areas of TrapezoidsGiven: The length of base 1 = 1 unit,The length of base 2 = 4 units.
The length of height = 3 units.
Formula used and calculation:The area of the trapezoid
= (Average of the two bases) × Height
Putting all the values in the above formula, we get
The area of the trapezoid
= {(1 + 4)/2} × 3
= 7.5 square units.
Hence, the area of the trapezoid is 7.5 square units.

The median of Group A is less than that of Group B.
The range of Group A is less than that of Group B.
The lower quartile of youp A is less than that of Group B.
Answer:
The median of Group A is less than that of Group B.
Step-by-step explanation:
Assume that your box-and-whisker plots look like those below.
1. Compare medians
Group A = 79
Group B = 79.5
The median of Group A is less than that of B
Correct.
2. Compare ranges
Group A: 82 - 76 = 6
Group B: 81 - 76 = 5
The range of Group A is greater than that of Group B.
Option B is wrong.
3. Compare Q1s
Group A: 78
Group B: 77
Q1 for Group A is less than that for Group B.
Option C is wrong.

Step-by-step explanation:
find the axis of symmetry for this parabola y=-2x^2-4x-11
write your answer as an equation
Answer:
x = - 1
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 ) , then the equation of the axis of symmetry is
x = - [tex]\frac{b}{2a}[/tex]
y = - 2x² - 4x - 11 ← is in standard form
with a = - 2 and b = - 4 , thus
x = - [tex]\frac{-4}{-4}[/tex] = - 1
x = - 1 is the equation of the axis of symmetry
Please answer correctly !!!! Will mark brianliest !!!!!!!!!!!!!!
Answer:
x - 5
Step-by-step explanation:
Again, we can just write the width as (x² - 25) / (x + 5) which will be x - 5.
Answer:
area = length x width
x² - 25 = x + 5 · width
(x - 5)(x + 5) = (x + 5)w
(x - 5)(x + 5) / (x + 5) = (x + 5)w / (x + 5)
x - 5 = w
Step-by-step explanation:
1. write down the formula of area.
2. since the area is a difference of squares, factor them into two binomials, and replace the length by its measure. you can use w for width
3. to get width, divide the one of the binomials with the length that matches together to get w.

The graph of the function f(x) = 5 cos (2x) is a reflection over the x-axis of the graph of g(x) =
Answer:
[tex]g(x)=-5\cos (2x)[/tex]
Step-by-step explanation:
The given function is
[tex]f(x)=5\cos (2x)[/tex]
If a function reflected over the x-axis, then x-coordinate remains same but the sign of y-coordinate is changed.
[tex]P(x,y)\Rightarrow P'(x,-y)[/tex]
If function f(x) is a reflection over the x-axis to get the of g(x), then the resultant function is
[tex]g(x)=-f(x)[/tex]
Substituting the value of function f(x), we get
[tex]g(x)=-5\cos (2x)[/tex]
Therefore, the required function is [tex]g(x)=-5\cos (2x)[/tex].

Seth sold 20% of his baseball cards during week one. During week two, he bought 20% more cards than he had after week one. If he now has 10 fewer cards, how many cards did he have originally? (he had more than 100 cards originally.)
Answer:
250 cards
Step-by-step explanation:
Let the number of baseball cards he originally had be x.
He sold 20% of the baseball cards after week one. This means that after week one the number of cards he had was:
x - (20/100 * x) = x - 0.2x = 0.8x
During week two he bought 20% more cards than he had after week one. This means that after week two, he had:
0.8x + (20/100 * 0.8x)
= 0.8x + (0.2 * 0.8x)
= 0.8x + 0.16x = 0.96x
He now has 10 fewer cards. This means that:
x - 10 = 0.96x
Collecting like terms:
x - 0.96x = 10
0.04x = 10
=> x = 10/0.04 = 250
He had 250 cards originally.

Answer:
quotient: 5x^4 -15x^3 +45x^2
Step-by-step explanation:
The division is performed in the attachment. At each stage, the quotient is the ratio of the highest-degree terms in dividend and divisor.
To find the dividend for the next step, subtract the product of quotient term and divisor from the current dividend. This is essentially the same way you do long division using integers.

in a survey of students 60% were in high school in 40% were in middle school of the high school students 30% had visited a foreign country if a survey of student is selected at random what is the probability that the student is in high school and has visited a foreign country?
Answer:
0.18
Step-by-step explanation:
Given: 60% students were in high school, 40% were in middle school and of the high school students, 30% had visited a foreign country
To find: probability that the student is in high school and has visited a foreign country
Solution:
Let x denotes total number of students
Number of students in high school = 60% of x = [tex]\frac{60}{100}x[/tex]
Number of students in middle school = 40% of x = [tex]\frac{40}{100}x[/tex]
Number of students who are in high school and have visited foreign country = 30% of Number of students in high school = [tex]\frac{30}{100}(\frac{60}{100})x=\frac{18}{100}x[/tex]
Probability that the student is in high school and has visited a foreign country = Number of students who are in high school and have visited foreign country/ Total number of students = [tex]\frac{\frac{18}{100}x}{x}=\frac{18}{100}=0.18[/tex]
