Answer:
90
Step-by-step explanation:
Step 1: Given data
Side of the rectangular prism (s): 3
Height of the rectangular prism (h): 6
Step 2: Calculate the surface area (SA) of the base
We will use the following expression, replacing the values for s and h.
SA = 2 × s² + 4 × s × h
SA = 2 × 3² + 4 × 3 × 6 = 90
The units are not provided but the SA should have the same units as s and h, but raised to the power of 2.
The ratio of solid beads to clear beads in a vase is 820. Select all the correct statements that tell if the operations will give an equivalent ratio.
Answer: C) Multiply the number of solid and clear beads by 2.
D) Divide the number of solid and clear beads by 4.
E) Multiply the number of solid and clear beads by 18.
Step-by-step explanation:
Multiplication and Division are the two arithmetic operations that are used to get an equivalent ratio or fraction.
So, the operations that will give an equivalent ratio are Multiplication and Division.
So that correct options are
C) Multiply the number of solid and clear beads by 2.
D) Divide the number of solid and clear beads by 4.
E) Multiply the number of solid and clear beads by 18.
Factoriz 5wp+15wp+20wr
Answer:
20w(p + r)
Step-by-step explanation:
It's readily evident that 5w is common to all three terms. Factoring out 5w, we get:
5w(p + 3p + 4r), or
5w(4p + 4r), or
20w(p + r)
Answer:
20w(p + r)
Step-by-step explanation:
We can factorize it in the following way...
5wp + 15wp + 20wr = 20wp + 20wr = 20w(p + r)

If f (2) = 60 – 5.
find x for f (x) = 13
Answer:
The required value of [tex]x[/tex] is [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
Given,
f (2) = 60 – 5
= (30 X 2) - 5
∴ f (x) = [tex]30x-5[/tex]
Again,
f (x) = 13 [given]
[tex]30x-5=13\\or, 30x= 13+5\\or, 30x=18\\or, x=\frac{18}{30} \\\\or, x=\frac{3}{5} \\[/tex]
∴[tex]x=\frac{3}{5}[/tex]
Verification:
f (x) = [tex]30x-5[/tex]
∴ f ([tex]\frac{3}{5}[/tex]) = (30 X [tex]\frac{3}{5}[/tex]) - 5
= 18 - 5
= 13
∴ The required value of [tex]x[/tex] is [tex]\frac{3}{5}[/tex]
a ladder reaches the top of a 20 foot building. the ladder is 4.5 feet away from the building. how long is the ladder?
a 24.5 feet
b 19.5 feet
c 20.5 feet
d 3.5 feet
Answer:
C
Step-by-step explanation:
do that with pithagoras:
20² + 4,5² = x²
400 + 20,25 = x²
420,25 = x²
x = [tex]\sqrt{420,25}[/tex]
x ~ 20,5
Letter C: 20,5 feet
The required length of the ladder is given as 20.5 feet. Option C is correct.
What are Pythagorean triplets?In a right-angled triangle, its side, such as the hypotenuse, is perpendicular, and the base is Pythagorean triplets.
Here,
The height of the building is 20 feet,
base length from the bottom of the building to the bottom of the ladder is 4.5 feet,
Let the hypotenuse length of the ladder be x,
Applying the Pythagoras theorem,
x² = 4.5² + 20²
x = √[420.25]
x = 20.5 feet
Thus, the required length of the ladder is given as 20.5 feet. Option C is correct.

. A Shopkeeper sells 81,590 bicycles in the month of June, he sells 61,753 3-Marks bicycles in the month of July, in the month of august he sells 9152 less than what he sold in July. How many bicycles are sold in 3 months?
Answer: 195,944 bicycles
Step-by-step explanation:
First find the number of bicycles sold in August.
August sales - July sales - 9,152
= 61,753 - 9,152
= 52,601 bicycles
The number of bicycles sold in 3 months is:
= June sales + July + August ,
= 81,590 + 61,753 + 52,601
= 195,944 bicycles

rational number between -1 and 1
Answer:
[tex]\dfrac{-1}{2}[/tex]
Step-by-step explanation:
We need to find ration numbers between -1 and 1.
Multiplying and dividing both -1 and 1 by 2.
[tex]\dfrac{-1\times 2}{2}=\dfrac{-2}{2}[/tex]
and [tex]\dfrac{1\times 2}{2}=\dfrac{2}{2}[/tex]
Now, the rational number between -2/2 and 2/2 is [tex]\dfrac{-1}{2}[/tex].

Answer:
An = 6 + (n-1)5
A25 = 120
Step-by-step explanation:
Given sequence;
6 , 11 , 16 , 21 , 26 , .......
Find:
25th term
Computation:
First term of AP (a) = 6
Common difference (d) = a2 - a1
Common difference (d) = 11 - 6
Common difference (d) = 5
An = a + (n-1)d
So,
An = 6 + (n-1)5
So,
If n = 25
A25 = 6 + (25 - 1)5
A25 = 6 + (24)5
A25 = 6 + 120
A25 = 120

Find the area of the figure to the nearest thousandth
Answer:
Total Area = 236.715 sq ft
Step-by-step explanation:
this is a composite figure made up of a circle and a rectangle; find the area of each and then add them together
A(circle) = πr²
= π(7.5²)
= 176.715
A(rectangle) = 15(4) which is 60
Total Area = 236.715 sq ft

Given circle Q with a measure of SR= 120° and a radius of 9 feet, as shown below.
Determine the arc length of SR. Use mathematics to explain how you determined your answer
Has photo ❤️
Answer:
18.84feet
Step-by-step explanation:
Length of an arc = rtheta
radius r = 9feet
theta = SR= 120°
Convert theta to radians
theta = 120π/180
theta= 2π/3
Length of the arc = 9 * 2π/3
L = 18π/3
L = 6π
L = 6(3.14)
L = 18.84feet
Hence the length of the arc is 18.84feet

Si el diametro de la Tierra es de 12 756 kilometros , ¿Qué tienes que hacer para saber cuál es la medida de su circunferencia
Answer:
40079 Km
Step-by-step explanation:
La circunferencia de la tierra está dada por;
C = 2πR
Dónde;
R = radio de la tierra
Tenga en cuenta que;
R = D / 2
Por eso;
C = 2πD / 2
C = πD
C = 3.412 * 12756 kilómetros
C = 40079 Km
A circle has a circumference of
3.14
3.143, point, 14 units.
What is the diameter of the circle?
Answer:
The diameter is 1 unit.
Step-by-step explanation:
The formula for circumference of a circle of diameter d is C = (3.14)d, where 3.14 is a close approximation of π (pi).
Here the circumference is given and is 3.14 units. Because C = 3.14d,
the diameter of this circle is 3.14/3.14, or simply 1 (unit).
