Answer:
Cost of each hamburger = $1.50
Step-by-step explanation:
Given:
Cost of 3 hamburger and 4 hotdog = $8.50
Cost of 3 hamburger and 6 hotdog = $10.50
Find:
Cost of each hamburger
Computation:
Cost of each hamburger = h
Cost of each hotdog = d
So,
3h + 4d = 8.50.....EQ1
3h + 6d = 10.50.......EQ2
EQ2 - EQ1
2d = 2
d = 1
3h + 4d = 8.50
3h + 4(1) = 8.50
3h = 4.50
h = 1.50
Cost of each hamburger = $1.50
54 out of the 72 teachers in a school staff meeting were first-year teachers. What percentage of the teachers in the meeting were first-year teachers?
Answer:
75%
Step-by-step explanation:
Total number of teachers = 72
100% = 72
1% = 72 ÷ 100 = 0.72
54 ÷ 0.72 = 75%

Answer:
( x + 2 )² + ( y - 1 )² = 25
Step-by-step explanation:
Circle equation - ( x - h )² + ( y - k )² = r²
Important notes:
(h,k) = center
r = radius
The first step would be to find the center
( it's hard to explain how to find the center point virtually but the center point is at (-2,1) )
Like stated before ( h , k ) = center point
* replace center point with (-2,1) *
( h , k ) = ( -2 , 1 )
h = -2
k = 1
* plug in the h and k values into the circle equation *
now we have ( x - ( -2) )² + ( y - 1 )²
Now to find the radius
We can find the radius by using the distance formula with the center point and any point on the circle's outline
The point chosen can vary but i chose (3,1)
Because the y value of the chosen point and the y value of the center are the same we can simply subtract the larger x value by the smaller x value to find the radius
3 - (-2)
the two negative signs cancel out
3 + 2 = 5
So the radius equals 5
* plug in the value of the radius into the equation *
Now we have
( x - (-2) )² + ( y - 1 )² = 5²
our final step is to simplify
- (-2) the two negative signs cancel out and it turns into +2
5² = 25
Our final answer would be ( x + 2 )² + ( y - 1 )² = 25

Answer:
Part A A. 400 sq ft.
Part B A. 509 sq ft
Step-by-step explanation:
Part A
Area of square = side squared
Since all the sides of the square are congruent and the perimeter is 80, then the length of each side is 80/4 = 20
A = 20^2 = 400 sq ft
Part B
C = πd
80 =
80/π = d
r = d/2 = 80/2π = 40/π
A = πr^2 = π(40/π)^2
= 1600π/π^2 = 1600/π = 1600/3.14 = 509 sq ft

Step-by-step explanation:
Let's solve your equation step-by-step.
n2−5n=24
Step 1: Subtract 24 from both sides.
n2−5n−24=24−24
n2−5n−24=0
Step 2: Factor left side of equation.
(n+3)(n−8)=0
Step 3: Set factors equal to 0.
n+3=0 or n−8=0
n=−3 or n=8
Answer:
n=−3 or n=8

help me pleasee shetwhis
Answer:
D
Step-by-step explanation:
When tossing a coin, there are two possibilities, heads or tails, thus one can rule out the first option. When rolling a pyramid-die, then there are four different possibilities, each one with an equally likely chance, and each one's outcome is non-dependant on the outcome of the coin toss. Thus options (B) and (C) can be ruled out. Therefore, option (D) is the only remaining valid option.
Can someone help me with this problem 3(x+1)=11 I need it step by step
Answer:
x = 2.66666667
Step-by-step explanation:
3(x + 1) = 11
We multiply both x and 1 by 3 and get
3x + 3 = 11
Now we subtract 3 from both sides
3x + 3 - 3 = 11 - 3
3x = 8
Now divide both sides by 3
3x/3 = 8/3
x = 2.66666667

Write the standard equation of the circle if the center is (-1,2), and a point on the circle is (2,6).
Plz help me someone
Answer:
(x+1)²+(y-2)² = 25
Step-by-step explanation:
Standard equation of the circle is expressed as;
(x-a)²+(y-b)² = r²
(a,b) is the center of the circle
r is the radius
Get the radius
r = √(x2-x1)²+(y2-y1)²
r = √(2+1)²+(6-2)²
r = √3²+4²
r = √9+16
r = √25
r = 5
Substitute into the formula
(x-a)²+(y-b)² = r²
a = -1, b = 2, r = 5
(x-(-1))²+(y-2)² = 5²
(x+1)²+(y-2)² = 25
This gives the required equation

Answer:
x = 11
Step-by-step explanation:
24+4x=6x+2
substract 2x from both sides 4x-4x and 6x -4x
24 = 2x + 2
Substract 2 from both sides 24-2 and 2-2
22 = 2x
Divide by 2 to both sides 22/2 and 2x/2
x = 11
An 18-ft tall tree casts a shadow of 25 feet. Find the angle of elevation of the sun.
Answer:
46.05degrees
Step-by-step explanation:
Given the following
Height of tree = 18ft (Opposite)
length of shadow = 25ft (hypotenuse)
Required
Angle of elevation
Sin theta = opp/hyp
Sin x = 18/25
sin x = 0.72
x = arcsin(0.72)
x = 46.05
Hence the angle of elevation of the sun is 46.05degrees
An architect designs two similar triangular patios. The first patio has angle measures of (x + 5)°, (y + 15)°, and 80°. The second patio has angle measures of (x + 25)°, 40°, and 60°. Find the values of x and y. please answer fast! i just need this one!
Answer:
x = 55° and y = 25°
Step-by-step explanation:
Since we have two triangular patios with angles (x + 5)°, (y + 15)°, and 80° and the second patio has angles, (x + 25)°, 40°, and 60° respectively, and the sum of angles in a triangle is 180, we have that,
(x + 5)° + (y + 15)° + 80° = 180° and
(x + 25)° + 40° + 60° = 180°
Simplifying both expressions, we have
x + 5° + y + 15° + 80° = 180° and
x + 25° + 40° + 60° = 180°
collecting like terms, we have
x + y + 5° + 15° + 80° = 180° and
x + 25° + 40° + 60° = 180°
Adding the like terms, we have
x + y + 100° = 180° and
x + 125° = 180°
So,
x + y = 180° - 100° and
x = 180° - 125°
Thus,
x + y = 80° and
x = 55°
So, y = 80° - x = 80° - 55° = 25°
So, x = 55° and y = 25°

Lucy Liu went shopping at Hollister with her friends together they spent a mean price of $40 on eight sweaters the first step and sweaters cost $50 $55 $30 $35 $39 $40 and $42 how much in dollars does the eighth sweater cost
Answer:he eighth sweater costs $29
Step-by-step explanation:
Let the price of the eighth sweater be re[presented as X
We know that
Mean Price =Total sum of cost of sweater bought/ Number of sweater'
Plugging in our known values we have that
40=$50+ $55+ $30+ $35+ $39+ $40 + $42+X /8
8 X 40 =291 +X
320=291 +X
X =320-291
X=29
Therefore, the eighth sweater costs $29
