Could you please write the question more clear?
A theater has 384 seats. Each row has 16 seats. The area model represents this situation. Area model showing 2 areas. The first is16 high and 20 wide, with a total of 320. The second is 16 high and x wide, with a total of 64. Part A What is the value of x in the area model? Enter your answer in the box. x = 4 I already answer part A what is the answer for part B?? Part B How many rows of seats are inside the theater? Enter your answer in the box. rows
Answer:
x=4
Rows = 24
There are 24 rows each having 16 seats making a total of 384.
Step-by-step explanation:
Part B
Total number of seats = Total of rows* Number of seats in each row
Let the total number of rows be y. The theater has 384 seats and each row has 16 seats. Putting the values
384= y * 16
y= 384/16= 24
There are 24 rows each having 16 seats making a total of 384.
Part A:
Area= length * width
Area 1= 320= 16 *20
Area 2 = 64
64 = 16 x
x= 64/16= 4
i need help with this
Answer:
30 square cm
Step-by-step explanation:
Key skills needed are: Triangle similarity, multiplication, proportions, subtraction
1) We first find that Triangle BCD is similar to triangle ACE. This is because they both have 1 right angle, and both share Angle BCD. Therefore, the other two angles are also the same measure.
2) Based on the statement above, 6/9 = 8/CE (CE just means the length of CE)
3) Solve this by cross multiplying -
[tex] \frac{6}{9} = \frac{8}{ce} [/tex]
This means that 6(CE) = 8(9)
4) Multiply it out: 6(CE) = 72
5) Divide by 6 and get CE = 12 cm.
6) Then use base time height to find the area of both triangles.
7) For triangle BCD: 6(8)/2 = 6(4) = 24 square centimeters
8) For Triangle ACE: 9(12)/2 = 9(6) = 54 square cm
9) To find the area of ABDE, you would subtract the are of triangle ACE by the area of triangle BCD
10) This is 54 - 24 = 30 square cm.

3 1/2 divided by 4 3/8
Answer:
0.8
Step-by-step explanation:

so 3.5 Divided by 4.375 is 0.8
what is the slope of the line that passes through (-5,0) and (-5,5)
Answer:
m=undefined
Step-by-step explanation:
the formula for slope (m) is (y2-y1)/(x2-x1)
here are the given points: (-5,0) and (-5,5)
we can label the points:
x1=-5
y1=0
x2=-5
y2=5
now substitute into the equation
m=(5-0)/(-5--5)
m=(5-0)/(-5+5)
m=5/0
m=undefined
the slope is undefined, because you cannot divide by 0

Can a right triangle be formed using these squares?
25, 144, 169
Answer:
Yes
Step-by-step explanation:
The two smaller squares have a sum of 169 which is the value of the larger square.
a^2 + b^2 = c^2
25 + 144 = 169
It can be done. Notice the figure below shows you how to arrange the squares to give the answer of a^2 + b^2 = c^2
Answer:
Yes, if we take the square roots of 25, 144 and 169 (5, 12, 13)
Not by using those measures as is (sides of a triangle with 25, 144 and 169).
Explanation:
A right triangle is a triangle with an angle of 90 degrees, and the side facing that angle of 90 degrees is called an hypotenuse.
The hypotenuse measurement squared is equal to the squared measurements of the other two sides:
c² = a² + b²
And those squares do verify the equation:
169 = 144 + 25
So, that's a rectangle (right) triangle, with sides measuring 5, 12 and 13.
Hope this helps :)

Answer: The fourth set of sides
Step-by-step explanation:
For a set of side lengths to form a right triangle, they have to satisfy the Pythagorean theory [tex](a^{2} +b^{2} =c^{2} )[/tex]
First set of sides
a = 7.5 b = 18 c = 21.5
[tex]a^{2} +b^{2} =c^{2}\\7.5^{2} +18^{2} =21.5^{2} \\56.25 + 324 = 462.25\\380.25 \neq 462.25[/tex]
Second set of sides
a = 7.5 b = 19.5 c = 21.5
[tex]a^{2} +b^{2} =c^{2} \\7.5^{2} +19.5^{2} =21.5^{2} \\56.25 + 380.25 = 462.25\\436.5 \neq 462.25[/tex]
Third set of sides
a = 18 b = 19.25 c = 21.5
[tex]a^{2} +b^{2} =c^{2} \\18^{2} +19.5^{2} =21.5^{2} \\324 + 380.25 = 462.25\\704.25 \neq 462.25[/tex]
Fourth set of sides
a = 7.5 b = 18 c = 19.5
[tex]a^{2} +b^{2} =c^{2} \\7.5^{2} +18^{2} =19.5^{2} \\56.25 + 324 = 380.25\\380.25 = 380.25[/tex]

What is the rate of change of the linear function that has a graph that passes through the points (1, 15) and (–2, 3)?
Only 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, . , -, and / are allowed in your answer. Answers that are mixed numbers must be entered as an improper fraction or decimal.
Answer:
4
Step-by-step explanation:
Rate of change is just slope, based on what I know.
Given 2 points : (x1, y1) and (x2, y2)... The slope would be [tex]\frac{y_{2}-y_{1} }{x_2-x_{1}}[/tex].
So for this problem we need to find the slope:
(1,15) and (-2,3) are the points. To find slope we do [tex]\frac{3-15}{-2-1}[/tex]. This simplifies into [tex]\frac{-12}{-3}[/tex].This then simplifies into 4.The rate of change is 4 based on my work.
2*10⁴-7³ please help
Answer:
19657
Step-by-step explanation:
By PEMDAS, we know we have to calculate the exponents first, then multiply the 2, and then subtract the 7³
2*10⁴ = 20000
20000 - 7³ = 19657

turquoise paint is made by mixing blue, green and yellow paint in the ratio 2.5 : 1.4 : 0.1 . how much of each colour is needed to make 1.5 litres of turquoise paint? write answers in the same order as the ratio (eg, blue, green, then yellow)
Answer: Blue color = 937.5 ml
green color = 525 ml
Yellow color= 37.5 ml
Step-by-step explanation:
Let the quantity of all kinds of paint required to make turquoise paint be 2.5 x(blue), 1.4 x( green), 0.1 x.(yellow).
Total turquoise color required =2.5x+1.4x+0.1x
[tex]\Rightarrow (2.5+1.4+01)x=1.5\\\\\Rightarrow\ 4x = 1.5\\\\\Rightarrow x=\dfrac{1.5}{4}\\\\\Rightarrow\ x=0.375[/tex] = 1.5 liters [given]
Blue color = 2.5 x 0.375 = 0.9375 liters = 937.5 ml [1 liter = 1000 ml]
green color = 1.4 x 0.375= 0.525 l = 525 ml
Yellow color= 0.1 x 0.375= 0.0375 =37.5 ml

Please!! Urgent
9514 1404 393
Answer:
(x, y) = (2, -6)
Step-by-step explanation:
Subtract the first equation from the second.
(8x -2y) -(5x -2y) = (28) -(22)
3x = 6
x = 2
Substitute this into either equation and solve for y.
8(2) -2y = 28
8 -y = 14 . . . . . . . . divide by 2
y = 8 -14 = -6 . . . . add y-14 to both sides
The solution is (x, y) = (2, -6).
