Answer:
21. Vol. = L ^ 3
or, 27000 = L ^ 3
or, cube root undefr 27000 = L
Therefore, Edge length = 30 cm
22.
a. v = l ^ 3
or, 64000 = l ^ 3
or, cube root under 64000 = L
or, l = 40 cm
Also,
surface area = 6 a ^ 2
= 6 * 40 ^ 2
= 6 * 1600
= 9600 cm ^ 2 #

FIND THE VALUE OF X
Answer: x = 29
Step-by-step explanation:
both angles are the same
so:
2x = 3x-29
2x - 3x = -29
-x = -29
x = 29
DEF, find the length of d, to the nearest tenth, given that ∠D=110o, e = 10cm and f = 14cm.
Answer:
d = 19.8 cm
Step-by-step explanation:
Use the law of cosines
[tex]d^{2} = e^{2} + f^{2} -2ef cos D\\d^{2} = 10^{2} + 14^{2} -2(10)(14) cos 110\\[/tex]
= 100 + 196 - 280 cos 110
= 296 - (-95.765640)
= 391.765640
[tex]d = \sqrt{391.7656401}[/tex]
d = 19.8 cm

wil give BRAINLIEST
pls answer correctly
Answer:
We conclude that the slope of the line containing the points (0, -2) and (3, -2) is:
[tex]m = 0[/tex]Step-by-step explanation:
Given that the line includes the points
(0, -2)(3, -2)We need to find the slope of the line containing the points between (0, -2) and (3, -2) using the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between (x₁, y₁) and (x₂, y₂)
In our case,
(x₁, y₁) = (0, -2)(x₂, y₂) = (3, -2)now substituting (x₁, y₁) = (0, -2) and (x₂, y₂) = (3, -2) in the slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{-2-\left(-2\right)}{3-0}[/tex]
[tex]m=\frac{-2+2}{3}[/tex]
[tex]m=\frac{0}{3}[/tex]
[tex]m = 0[/tex]
Therefore, we conclude that the slope of the line containing the points (0, -2) and (3, -2) is:

Need to find x, and measure of angle DEF
Answer:
x = 5
[tex] m\angle DEF = 90\degree [/tex]
Step-by-step explanation:
GE is the angle bisector of quadrilateral DEFG,
Thus, by angle bisector property:
9x°= (5x + 20)°
9x = 5x + 20
9x - 5x = 20
4x = 20
x = 20/4
x = 5
[tex] m\angle DEF = 9x\degree + (5x+20)\degree [/tex]
[tex] m\angle DEF = (14x+20)\degree [/tex]
[tex] m\angle DEF = (14\times 5+20)\degree [/tex]
[tex] m\angle DEF = (70+20)\degree [/tex]
[tex] m\angle DEF = 90\degree [/tex]
2k+16=30 i need help with this before March 2nd ASAP
Answer:
k = 7
Step-by-step explanation:
The goal is to solve for the variable k in this problem.
To do this, we need to get k by itself!
2k + 16 = 30
Start by subtracting the 16 over from the left side to the right
2k + 16 - 16 = 30 - 16
Simplify by subtracting 16 from 16 on the left side (which is 0) and 16 from 30 on the right side (which is 14).
2k = 14
Then finish by dividing both sides by 2 to get k by itself.
[tex]\frac{2k}{2}[/tex] = [tex]\frac{14}{2}[/tex]
Simplify by dividing 2 by 2 on the left side (which is 1) and 14 by 2 on the right side (which is 7).
k = 7
[tex]\huge\text{Hey there!}[/tex]
[tex]\huge\textbf{Equation:}[/tex]
[tex]\mathbf{2k + 16 = 30}[/tex]
[tex]\huge\textbf{Solving for:}[/tex]
[tex]\mathbf{2k + 16 = 30}[/tex]
[tex]\huge\textbf{Subtract \boxed{\bf 16} to both sides:}[/tex]

[tex]\mathbf{2k = 14}[/tex]
[tex]\huge\textbf{Divide \boxed{\bf 2} to both sides:}[/tex]
[tex]\mathbf{\dfrac{2k}{2} = \dfrac{14}{2}}[/tex]
[tex]\huge\textbf{Simplify it:}[/tex]
[tex]\mathbf{x = \dfrac{14}{2}}[/tex]
[tex]\mathbf{x = 14\div2}[/tex]

420 meters
420 centimeters
4,200 centimeters
Answer:
4,200 metersHow do you convert meters to kilometers formula?Meters to Kilometers Conversion1 Meter (m) is equal to 0.001 kilometer (km). To convert meters to km, multiply the meter value by 0.001 or divide by 1000. For example, to convert 100 m to km, multiply 100 by 0.001, that makes 0.1 km is 100m .

Priyanka drives at 45km/h and reaches Delhi in 5 hours.What time will she take to complete the same journey if she increases her speed by 5km/h ?
Answer: Increasing her speed by 5km/h, she will take 4.5 hours to complete the journey.
Step-by-step explanation:
Step 1
Speed= Distance / TIme
Given Speed = 45km/h
and Time = 5 hours
Distance covered = Speed x Time
= 45 km/h x 5 hours
=225 kilometres.
Step 2
Increasing her speed by 5km/h makes the new Speed = 45 +5 = 50 km/h
At the same Distance of 225 km
Therefore she will complete the journey in
Time = Distance/ Speed
=225km/ 50km/h
=4.5 hours

Answer:
5 I don't know if it's right but I am a trying
1. Find the volume of a cube with a side of 9 cm.
2. Find the perimeter of a rectangle whose length is 4
cm and breadth is 3 cm.
3. Find the area of a square of side 11 m.
4. Find the area of a rectangle that is 14 m long and 5
m wide.
5. Find the perimeter of an equilateral triangle with
side 15 cm.
I'm in tension right now I am studying for exams and I'm tired it would be nice if you help me out!
Step-by-step explanation:
1. Given,
Side of the cube = 9 cm
Therefore, volume of the cube = side × side × side
= 9cm × 9cm × 9cm
[tex] = 729 {cm}^{3} (ans)[/tex]
2. Given,
Length of the rectangle = 4cm
Breadth of the rectangle = 3cm
Therefore, perimeter of the rectangle = 2(l+b)
= 2(4cm + 3cm) = 2 × 7cm = 14 cm (Ans)
3. Given,
Side of a square = 11 m
Therefore, area of the square = side × side
= 11 m × 11 m
[tex] \: = {121cm}^{2} (ans)[/tex]
4. Given,
Length of the rectangle = 14 m
Width of the rectangle = 5 m
Therefore, area of the rectangle = l × b
= 14 m × 5 m
[tex] = 70 {m}^{2} (ans)[/tex]
5. Given,
Side of the equilateral triangle = 15 cm
Therefore, perimeter of the triangle = 3 × side
= 3 × 15 cm = 45 cm (Ans)
