A rectangular prism has a volume of 100 cm3. The length of the prism 25 cm, the height is 2 cm, but the width is unknown. What is the width of the rectangular prism?
4cm
2cm
3cm
none of the above
Answer:
w = 2 cm
Step-by-step explanation:
100 = 25 x 2 x w
w = 2 cm
The width of the rectangular prism is 2 cm.
What is volume?Volume is the amount of space occupied by a solid shape.
To calculate the width of the rectangular prism we use the formula below.
Formula:
V = lwh................. Equation 1Where:
l = Length of the prismw = Width of the prismh = Height of the prismV = Volume of the prismMake w the subject of the equation
w = V/lh................Equation 2From the question,
Given:
l = 25 cmh = 2 cmV = 100 cm³Substitute these values into equation 2
w = 100/(25×2)w = 100/50w = 2 cmHence, the width of the rectangular prism is 2 cm.

Answer:
x≥−3
Step-by-step explanation:
Let's solve your inequality step-by-step.
2x+3/ −3 ≤1
Step 1: Simplify both sides of the inequality.
−2/ 3 x−1≤1
Step 2: Add 1 to both sides.

Find the volume of a right circular cone that has a height of 12.4 m and a base with a
diameter of 5.1 m. Round your answer to the nearest tenth of a cubic meter.
Answer:
84.4
Step-by-step explanation:
done
Volume of a right circular cone is 84.39 m³
What is volume?
The amount of space occupied by a three-dimensional figure as measured in cubic units.
Given:
height = 12.4 m. base diameter= 5.1 m, radius= 5.1/2 m
Volume of right circular cone= 1/3* π* r²*h
= 1/3*3.14* 2.55*2.55*12.4
= 84.39 m³
Hence, the volume of right circular cone is 84.39 m³

The first three terms of arithmetic progression are -5,-1 and 3.Find the six term.
Answer:
15
Step-by-step explanation:
The pertinent general formula for this arithmetic progression is
a(n) = a(1) + d(n - 1), where d is the common difference. That difference is d = 4.
Here, a(n) = -5 + 4(n -1)
Therefore, a(6) = -5 + 4(5) = 15
Answer:
It is 15.
Step-by-step explanation:
Alright, first lets find the pattern. Since its a arithmetic sequence, it has something to do with adding/subtracting.
With the values, -5, -1, and 3. Notice something about them? -1 is 4 more than -5 & 3 is 4 more than -1. There's a pattern! The pattern is that for every new term, it is 4 more than the one before it.
With this, we can make a table to find the 6th term!
(Given)
1st Term: -5
2nd Term: -1
3rd Term: 3
Now, continue adding 4 to each term...
4th Term: 7
5th Term: 11
6th Term: 15
For the 6th term, it has been found that the answer's 15.

Answer:
38
Step-by-step explanation:
The area of a kite is equal to half the product of the diagonals
To find the area we must first find the measures of the diagonals
short diagonal = 2 + 2 = 4
longer diagonal = 8 + 11 = 19
We then calculate the area by multiplying the two diagonals together and then dividing that by 2
A = 19 * 4 = 76
76 / 2 = 38
Hence, the area of the kite is 38m²
38m².
Answer:
Solution given;
diagonal 1=8+11=19m
diagonal 2=2+2=4m
the area of a kite =½*diagonal 1*diagonal 2
=½*4*19=38m²
The area of kite is 38m².

A man drops a ball from the top of a 300 foot cliff. The height of the falling ball is modeled
by h(t)=-16t2+300 where h is in feet and t is in seconds. How long does it take for the ball to be 44 feet above the ground?
Answer:
The ball reaches 44 ft above the ground after 4 sec.
Step-by-step explanation:
Set h(t)=-16t^2+300 equal to 44 feet and solve for time, t. Indicate exponentiation with " ^ "
-16t^2 + 300 = 44 becomes
-16t^2 + 256 = 0, or 16t^2 = 256. Then, taking the square root of both sides, we get:
4t = 16, or t = 4 sec. The ball reaches 44 ft above the ground after 4 sec.
The ball will take 4 seconds.
What are quadratic equations?A quadratic equation, or simply "quadratics," is a polynomial equation with a degree of two as its highest. This is how it is expressed:
a x² + b x + c = 0 where x is the unknown variable and the constant terms are a, b, and c.
Given equation of height h(t) = -16t² + 300...…..(1)
where h is height in feet and t is time in seconds,
and height at t = 0 is 300 feet
when ball is 44 feet above ground then time is,
put h = 44 in equation 1
44 = -16t² + 300
16t² = 300 - 44
t² = 256/16
t = √16
t = 4
Hence time taken by ball is 4 seconds.

Answer:
Option B
Step-by-step explanation:
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
Now substitute the measures of each side in the formula,
(13)² = x² + (12)²
169 = x² + 144
x² = 169 - 144
x² = 25
x = √25
x = 5
Therefore, Option B will be the correct option.
