Answer:
J. 56
Step-by-step explanation:
The picture in this question can be a little deceiving. Each rectangular glass pane is 3 by 10 inches. This means that the picture of the 4 panes overlapping, leaves the center square open. The open area has your inner edges. The question asks for the sum of the inner and outer edges.
Every pane is 10 inches long, so the out perimeter of the figure is 40 inches because the figure has four sides. The rectangles overlap, creating 3 by 3 inch square. 3 inches off either side of a pane leaves 4 inches as the length for the edge of the inner square. Therefore, the perimeter of the inner square is 16 inches.
Outer Perimeter + Inner Perimeter = 40 + 16 = 56 inches
Let
x-------> the number of shirts
y------> the number of jeans
we know that
-------> equation
If she sold the shirts at profit and jeans at profit, her total profit was
so
-------> equation
we have the following system of equations
-------> equation
-------> equation
using a graph tool
see the attached figure
The solution of the system is the intersection both graphs
the solution is the point
that means
therefore
the answer is
the number of shirts is
the number of jeans is
Answer:
What class you be taking
Step-by-step explanation:
To calculate the range of the number of students ages 7 to 18 who would likely say that "finding new resources for Earth" is the most important benefit of future flight, we need to consider the margin of error.
The margin of error (MOE) is ±3%, which means the actual percentage of students who think this way could be 3% higher or 3% lower than the survey result.
First, let's find out the percentage of students who chose "finding new resources for Earth" as the most important benefit of future flight based on the survey:
Percentage from the survey = \( \frac{4300}{40000000} \times 100\% = 0.01075\% \)
Now, we need to calculate the upper and lower bounds considering the margin of error:
Upper bound = \( 0.01075\% + 3\% = 0.04075\% \)
Lower bound = \( 0.01075\% - 3\% = -0.01925\% \)
The lower bound cannot be negative, so we consider it as 0%.
To find the number of students in the United States who would likely say that "finding new resources for Earth" is the most important benefit of future flight, we use the upper bound percentage:
\( 0.04075\% \times 40000000 = 16300 \)
So, the range is approximately 16,300 students to 4,300 students.
16
–8
–16
Step-by-step explanation: A more simple approach is realizing that the blocks show 8 x tiles and 1 x^2 tile. The 8 x tiles are on either side of the x^2 tile which is 4 x tiles on each side. So as we can see we can multiply each side together. 4x4 = 16. So that is how you get 16 without having to work it out.
B=(xy + x)(xy + x)
C=(2x – 3)(–3 + 2x)
D=(16 – x2)(x2 – 16)
E=(4y2 + 25)(25 + 4y2)
The correct answers are:
B=(xy + x)(xy + x) ; C=(2x – 3)(–3 + 2x) ; and E=(4y² + 25)(25 + 4y²)
Explanation:
In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same. For (xy+x)(xy+x), are multiplying two identical binomials.
For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order. The same is true of (4y² + 25)(25 + 4y²).
Answer:
A and E and C
Step-by-step explanation:
A perfect square trinomial can be written as the square of a binomial.
