Answer:
L=93
Step-by-step explanation:
So basically you need to know the formula beforehand the formula to find the length of a rectangle what is P=2(l+w) so to find for L the equation will be L=P/2-W=294-54=93 Therefore 93 is L

The perimeter of a square is 68 feet. What is the length of one of its sides? Explain your work.
Answer:
17 feet
Step-by-step explanation:
Since a square has 4 sides, you have to do 68 / 4 to find one of the sides.
68/4 = 17
And to check, if you add up all sides...
17+17+17+17 = 68

2(4y-9)=14 solve for y
Answer:
y = 4
Step-by-step explanation:
2(4y - 9) = 14
8y - 18 = 14
8y = 32
y = 4
Answer:
y = 4
Step-by-step explanation:
Simplifying
2[4y + -9] = 14
Reorder the terms:
2[-9 + 4y] = 14
[-9 * 2 + 4y * 2] = 14
[-18 + 8y] = 14
Solving
-18 + 8y = 14
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '18' to each side of the equation.
-18 + 18 + 8y = 14 + 18
Combine like terms: -18 + 18 = 0
0 + 8y = 14 + 18
8y = 14 + 18
Combine like terms: 14 + 18 = 32
8y = 32
Divide each side by '8'.
y = 4
Based on the figure, which of the following statements
CANNOT be proven?
Answer:
the final one
Step-by-step explanation:
to figure this equation out it is easier to add numbers to the angles
for 1 we can have it as 100 and for 2 we can have it as 80
that means 3 is 100 and 4 is 80
100 - 80 is also 100 - 80 so the first one can be proven
100 + 80 = 180 so the second one can be proven
80 = 80 so the third one can be proven
80 + 80 = 100 + 100 is not correct because it turns into 160 = 200 which is incorrect so the last one cannot be proven
Answer:
4th option : m∠1 + m∠3 = m∠2 + m∠4Step-by-step explanation:
By VOA theorem, vertically opposite angles are equal.
∠1 = ∠3∠2 = ∠4⇒ You can write : ∠1 + ∠2 = ∠3 + ∠4
⇒ or ∠4 - ∠1 = ∠3 - ∠2
⇒ The 4th option does not give it correctly

Answer:
Step-by-step explanation:
4x + 9y = 5
-4x + 7y = 11
Isolate y for 4x + 9y = 5
9y = 5-4x
y = (5-4x) / 9
Now plug it in this equation: -4x + 7y = 11
-4x + 7[(5-4x)/9] = 11
now just solve it.
-4x + (35 - 28x / 9) = 11
multiply both sides by 9
-36x + 35 - 28x = 99
-64x = 64
divide both sides by -64

Is it:
Inconsistent
Not enough information
Coincident
Consistent Independent
Answer:
(a) Inconsistent
Step-by-step explanation:
Two linear equations can be compared by putting both of them in standard form. Here, that means removing a common factor from the coefficients of the first equation.
3x -6y = -12 . . . . given first equation
x -2y = -4 . . . . . . divide by 3
Compare this to the second equation:
x -2y = -8
The constants (-4, -8) are different, so there are no values of x and y that can satisfy both equations. The equations are described as inconsistent.
Answer:
InconsistentStep-by-step explanation:
Equation 1
3x - 6y = -12Divide throughout by 3 to simpliest formx - 2y = -4Equation 2
x - 2y = -8On comparison, it is seen that the slopes are same, but the y-intercepts are different.
This means this has no solution, or the graph is inconsistent.

Region R is bounded by the curves y = 4x^2 and y = 4. A solid has base R, and cross sections perpendicular to the y-axis are semicircles with the diameter lying in R. The volume of this solid is
A. pi/4
B. pi/2
C. pi
D. 2pi
Each cross section has a diameter equal the horizontal distance between the two "halves" of the parabola. We have
y = 4x² ⇒ x = ±√y/2
so the diameter for some given y would be √y/2 - (-√y/2) = √y.
The volume of a cross section with thickness ∆y is then
π/2 (√y/2)² ∆y = π/8 y ∆y
The total volume of the solid would then be
[tex]\displaystyle \int_0^4 \frac\pi8 y \, dy = \frac\pi8 \times \frac12 y^2 \bigg|_{y=0}^{y=4} = \boxed{\pi}[/tex]

For percentage, you take the percent symbol and move it two spaces to the left and make it a decimal, hence the .32 and then you multiply it by the integer you want to find the percent of, 130.
Answer:
0.32 x 130
Step-by-step explanation:
A percentage is out of 100;
32% = 32/100
32/100 = 0.32
32% of 130 is a multiplication problem (of : multiplication).
0.32 x 130 = 41.6

MissSpanish2.) If ZA = (20 – 2m)º and ZD = (m – 130°, what is the value of m?
Answer:
m = 50
Step-by-step explanation:
∠ D and ∠ A are vertically opposite angles and are congruent , then
m - 130 = 20 - 2m ( add 2m to both sides )
3m - 130 = 20 ( add 130 to both sides )
3m = 150 ( divide both sides by 3 )
m = 50

Christopher determines the system of s(x) and t(x) has only one solution.Which system is Christopher solving?
Christopher is solving a system of equations that has one solution and can be seen in Option C.
What is a system of equations?A system of equations is more than one equation that can be solved together to get a unique solution. In this situation, the power of the equation must be in one degree.
A quadratic equation is an algebraic equation whose power is raised to the second degree.
However, if their power is not in one degree, they are regarded as a quadratic equation and it usually produces two solutions.
From the given options, we can see that only option c is not a quadratic equation, Hence, it is the right answer.

4. Prove that the two figures in the graph below are similar.
Estimate the perimeter and the area of the shaded figure.
A shaded composite figure is shown on a grid. The figure is made up of an isosceles triangle and an isosceles trapezoid. The triangle has a base of 6 units and height of 3 units. The trapezoid has a shorter base of 4 units, longer base of 6 units, and height of 3 units. The longer base of the trapezoid is aligned with the base of the triangle.
perimeter: about
units
area: about
square units
The shapes in the composite figures are a triangle and a trapezoid
The area of the figure is about 24 square units
The area of the figureThe dimensions of the figure are given as:
Triangle
Base = 6 unitsHeight = 3 unitsTrapezoid
Shorter base = 4 unitsLonger base = 6 unitsHeight = 3 unitsThe longer base of the trapezoid and the base of the triangle are aligned.
So, the area is:
Area = Area of triangle + Area of trapezoid
This gives
Area = 0.5 * base * height + 0.5 * (sum of bases) * height
So, we have:
Area = 0.5 * 6 * 3 + 0.5 * (4 + 6) * 3
Evaluate
Area = 24

In how many ways could you choose 3 side dishes from a menu that offers 5 vegetable side dishes
and 3 starches if you want at least one vegetable and one starch?
Using the Fundamental Counting Theorem, it is found that there are 90 ways to choose the three side dishes.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem:
For the vegetable, there are 5 options, hence [tex]n_1 = 5[/tex].For the starch, there are 3 options, hence [tex]n_2 = 3[/tex].The remaining dish is free, which means that there are 5 + 3 - 2 = 6 options, hence [tex]n_3 = 6[/tex].Then:
N = 5 x 3 x 6 = 90.
There are 90 ways to choose the three side dishes.
