Find the unknown side length, x. Write your answer in simplest radical form.
A. 4132
B. 22
C. 16/5
D. 16 V13
Answers
Answer:
C
Step-by-step explanation:
Use the pythagorean theorem.
32^2+b^2=48^2
1024+b^2=2304
Subtract 1024
b^2=1280
Square root
b=sqrt(1280)
Now simplify sqrt(1280)
sqrt(1280) = sqrt(256*5)
You can take the square root of 256 since it is a perfect square so take it out of the radical.
sqrt(256*5)=16sqrt(5)
So the answer is c, 16[tex]\sqrt{5}[/tex]
Answer:
C. 16/5
Step-by-step explanation:
pythagorean theorem
a^2 + b^2 = c^2
divide 48 and 32 by 16
a= 2 c= 3
4 + b^2 = 9
b^2 = 5
b = √5
then multiply 16 with √5
which =
16√5

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?
Answers
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.

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
x = 1

B. pi/2
C. pi

Answers
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

Based on the figure, which of the following statements
CANNOT be proven?
Answers
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

Step-by-step explanation:
I took the test and it was correct.
The measure of the side length DE is 6.38 units after applying the tan ratio in the right-angle triangle option (C) 6.38 units is correct.
What is a right-angle triangle?It is a triangle in which one of the angles is 90 degrees and the other two are sharp angles. The sides of a right-angled triangle are known as the hypotenuse, perpendicular, and base.
We have a right-angle triangle given:
Triangle DEF contains right angle E. If angle D measures 50° and its opposite side measures 7.6 units,
After drawing the triangle:
Applying the tan ratio in the right-angle triangle:
tan50 = EF/DE
tan50 = 7.6/DE
DE = 7.6/tan50
DE = 6.377 ≈ 6.38 units
Thus, the measure of the side length DE is 6.38 units after applying the tan ratio in the right-angle triangle option (C) 6.38 units is correct.

Is it:
Inconsistent
Not enough information
Coincident
Consistent Independent
Answers
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.

2(4y-9)=14 solve for y
Answers
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

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.

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
The figure is needed to determine the perimeter
Hence, the area of the figure is about 24 square units
