Answer:
The original dimensions of the piece of metal are
Length: 36 inches
Width: 21 inches
Step-by-step explanation:
Let
x ----> the original length pf the piece of metal
y ----> the original width pf the piece of metal
we know that
----> equation A
The volume of the box is equal to
we have
substitute in the formula of volume
----> equation B
substitute equation A in equation B
solve for y
Solve the quadratic equation by graphing
using a graphing tool
The solution is y=21
Find the value of x
therefore
The original dimensions of the piece of metal are
Length: 36 inches
Width: 21 inches
Answer:
104°
Step-by-step explanation:
The principle to apply here is that angle subtended at the center of a circle is twice the angle at circumference.
Angle subtended at arc = 52°
Angle at the center = 2 x 52° = 104°
Please write <span>x + y = 24 3x + 5y = 100
as:
</span><span>x + y = 24
3x + 5y = 100
What does this arrangement tell us?
There are a total of 24 test questions.
Since x represents the # of 3-pt questions, 3x is the total # of points obtained by getting 3-pt questions correct.
</span>Since y represents the # of 5-pt questions, 5y is the total # of points obtained by getting 5-pt questions correct.
The greatest possible # of points earnable here is 100.
Answer:
D.
Step-by-step explanation:
If the triangle has one angle that is equal to 90 then it is a right triangle.
<span>A)Both m(x) and p(x) cross the x-axis at 7.
B)Both m(x) and p(x) cross the y-axis at 7.
C)Both m(x) and p(x) have the same output value at x = 7.
D)Both m(x) and p(x) have a maximum or minimum value at x = 7.
m(x) = p(x) at x = 7
</span><span>
True statement about x = 7.
C)Both m(x) and p(x) have the same output value at x = 7. </span><span>
