The two parallelograms in the figure are similar. What is the value of x?
A. 26
B. 24
C. 28
D. 30.4
Answer:
The answer is D, 30.4
Step-by-step explanation:
Because the two parallelograms are similar, the relationship between the sides of them are directly proportional.
So:
[tex]\frac{9}{8} =\frac{x}{27}[/tex]
Cross multiply
8x = 243
÷8 both sides
x = 30.375 ≈ 30.4
The answer is D, 30.4
ANSWER
D. 30.4
EXPLANATION
The two parallelograms are similar, therefore the corresponding sides must be in the same proportion:
[tex] \frac{x}{9} = \frac{27}{8} [/tex]
Multiply both sides of the equation by 8. This implies that,
[tex]x = \frac{27}{8} \times 9[/tex]
[tex]x = 30.375[/tex]
Rounding to the nearest tenth gives us:
[tex]x = 30.4 \: units[/tex]
A square garden has sides 50 ft long.
You stretch a hose exactly from one
corner of the garden to another
corner across the garden's diagonal.
How long is the hose?
Answer:
The hose is ~70.71 ft long.
Step-by-step explanation:
We need to use Pythagorean theorem to figure this out. ( A^2 + B^2 = C^2)
So we first need to square 50 two times, since that's the length and height of the garden. This equals 5000.
Then we just need to find the root of 5000! This rounds out to about 70.71 ft.
Hope I could help! :)
The length of the hose which is stretched from one corner of the garden to another corner across the diagonal of it is 70.72 ft
What is the diagonal of the square?The diagonal of the square is the distance from opposite vertices of it. There are two diagonals in a square which are equal in measure.
To find the diagonal of the square, the following formula is used.
d=a√2
Here, (a) is the length of the side of the square.
The side of a square garden is 50 ft long. One hose is stretch from one corner of the garden to another corner across the diagonal of it. Thus, the length of the diagonal is,
d=a√2
d=(50)√2
d=70.72 ft
Thus, the length of the hose which is stretched from one corner of the garden to another corner across the diagonal of it is 70.72 ft

Two angles of a parallelogram measures 57 degrees. What is the measure of other two angles?
Answer:
123
Step-by-step explanation:
In a parallelogram, both pairs of opposite angles are congruent. Also, both pairs of opposite sides are parallel, meaning there are consecutive interior angles. Consecutive interior angles equal 180, so simply subtract 57 from 180 to find your missing angles.

1 bell shape
2 to find probability when sampling
EXPLANATION
1 In a normal distribution, the mode,mean and median are equal.
As a result, the distribution is neither skewed to the right or left.
The shape of the normal distribution looks like a bell.
That is why it is also called the bell curve.
2. The area under the normal curve is 1.
The line of symmetry of the bell shaped distribution divides it into two halves with area 0.5 each.
The normal curve is therefore used to find the probabilities of a sample distributions.

where [tex]r[/tex] is the radius of the cylinder's base and [tex]h[/tex] is the height of the cylinder.
Given:
- Radius [tex]\( r = 18.8 \)[/tex] feet
- Height [tex]\( h = 24 \)[/tex] feet
- [tex]\( \pi \approx 3.14[/tex]
Now, let's calculate the volume:
[tex]\[ V = 3.14 \times (18.8 \text{ feet})^2 \times 24 \text{ feet} \][/tex]
[tex]\[ V = 3.14 \times 18.8^2 \times 24 \][/tex]
[tex]\[ V = 3.14 \times 353.44 \times 24 \][/tex]
[tex]\[ V = 3.14 \times 8482.56 \][/tex]
[tex]\[ V \approx 26694.1216[/tex]
To the nearest whole number, the volume of the aquarium is approximately:
[tex]\[ V \approx 26694 \] cubic feet.[/tex]
Therefore, the volume of the cylindrical aquarium to the nearest whole number is [tex]\(\boxed{26694}\)[/tex] cubic feet.

Answer:b
Step-by-step explanation:
You're answer is b. All you have to do is a measurement
Answer:
B) 1/2 (154° - 46°)
Step-by-step explanation:
Here ∠XYZ is an angle subtended by two chords from a point outside of the circle.
It is a one of the circle.
If the angle subtended by two chords from the outside point of the circle, the measure of the angle is 1/2 times difference of the major arc and minor arc.
Here Major arc = 154° and minor arc = 46°
Applying the rule, we get
m∠XYZ = [tex]\frac{1}{2} (Major arc - Minor arc)[/tex]
m∠XYZ = 1/2 (154° - 46°)

Kamal solved an equation as shown below. 3(x-8)=x+2x+7 3x-24=3x+7 -24=7 What is the solution to Kamal’s equation?
There is no solution to Kamal's equation because -24 ≠ 7
How to solve the problem
The equations are given as
i. 3(x-8)=x+2x+7
ii. 3x-24=3x+7
iii. -24=7
We have to expand the first equation
3(x-8)=x+2x+7
this would produce the second equation
3 * x - 3 * 8 = 3x + 7
we have
ii. 3x-24=3x+7
from here we have to take like terms on put them on same side
3x - 3x = 7 + 24
0 = 31
or from 3x-24=3x+7
the 3x is eliminated
-24 = 7
But we know that -24 ≠ 7. Hence no solution.
the height of an equilateral triangle is 4 square root 3. What is the perimeter of the equilateral triangle
Answer:
The perimeter of the equilateral triangle, P = 24 units
Step-by-step explanation:
All sides of an equilateral triangle are equal. The height of the equilateral triangle is given by :
[tex]h=\dfrac{\sqrt{3} }{2}\times a[/tex]
a is the side of triangle
If the height of an equilateral triangle is, [tex]h=4\sqrt{3}[/tex]
Equation (1) becomes,
[tex]a=\dfrac{2h}{\sqrt{3} }[/tex]
Put h in above formula. So,
[tex]a=\dfrac{2\times 4\sqrt{3}}{\sqrt{3} }[/tex]
a = 8
So, the side of triangle is 8. The sum of all sides is called perimeter of any figure. So,
[tex]P=8\times 3[/tex]
P = 24 units
So, the perimeter of the equilateral triangle is 24 units. Hence, this is the required solution.
Final answer:
To find the perimeter of the equilateral triangle with a height of 4√3, we determine the side length using the relationship between the height and side length of the triangle, and then multiply by three to get a perimeter of 24 units.
Explanation:
The height of an equilateral triangle is given as 4√3. To find the perimeter, we need to determine the length of a side of the triangle. In an equilateral triangle, the height (h) creates a right-angled triangle where the height is opposite to a 60° angle, and the half of a side of the triangle (half-base) is adjacent to it. The relationship is given by the equation h = (a√3)/2, where a is the side length of the equilateral triangle. By substituting the height with 4√3, we get:
4√3 = (a√3)/2 → a = 8
Since all sides of an equilateral triangle are equal, the perimeter is three times the side length, which means the perimeter P = 3 × 8 = 24 units.
A square on a coordinate plane is translated 9 units down and 1 unit to the right. Which function rule describes the translation?
Answer:
x+1, y-9
Step-by-step explanation:
Answer:
(x, y) ----> (x +1, y - 9)
Step-by-step explanation:
A square on a coordinate plane is translated 9 units down and 1 unit to the right.
Let's (x, y) is coordinate plane.
Here x represents the horizontal move and y represents the vertical move.
It is translated 9 units down and 1 unit right.

5) TUW and SUT are___ angles
Answer:
1. 30
2. 150
3. obtuse
4. acute
5. Adjacent
Step-by-step explanation:
The correct expression for the angles are;
1) m SUT equals 30 Degrees.
2) m TUW equals 150 degrees
3) TUW is obtuse angle
4) SUT is acute angle
5) TUW and SUT are Adjacent angles
What are obtuse acte and adjacent angles?Similar to corners, right angles have a 90° measure. Acute angles are less than ninety degrees. More than 90° but less than 180° are obtuse angles. Additionally, a straight angle is 180°, which is the point at which two lines merge into one by going in the same direction.
Any angle is composed of two rays that converge at a point known as the vertex. When two angles share a ray, it indicates that they are adjacent to one another.

The area of the shaded figure is 10053.08 [tex]mm^2[/tex].
To find the area of the shaded region, we can use the following steps:
Calculate the area of the larger circle.
Calculate the area of the smaller circle.
Subtract the area of the smaller circle from the area of the larger circle.
The area of a circle is calculated by multiplying the radius squared by pi. The radius of the larger circle is 60 mm, so the area of the larger circle is:
[tex]A_l[/tex] = [tex]\pi[/tex] * [tex](60 mm)^2[/tex]
= 11309.72 [tex]mm^2[/tex]
The radius of the smaller circle is 20 mm, so the area of the smaller circle is:
[tex]A_s[/tex] = [tex]\pi[/tex] * [tex](20 mm)^2[/tex]
= 1256.64 [tex]mm^2[/tex]
The area of the shaded figure is calculated by subtracting the area of the smaller circle from the area of the larger circle:
A = [tex]A_l[/tex] - [tex]A_s[/tex]

<CDH = 180° - 70°
<CDH = 110°
Answer:

Step-by-step explanation:
We are given that <1=70. Using that, we know that <5 also equals 70 because of the definition of vertical angles, we then can find <2 also by subtracting 70 from 180 and dividing it by 2 to get 55. <4=<2 and <6=<5, so using substitution we can get m<CDH=125
