Answer:
x=3
Step-by-step explanation:
4x-8=4
4x=12
4x/4=12/4
x=3
Answer:
x = 3
Step-by-step explanation:
Add 8 to both sides.
4x = 4 + 8
Simplify 4 + 8 to 12.
4x = 12
Divide both sides by 4.
x = 12 ÷ 4
Simplify 12 ÷ 4 to 3
x = 3

꧁____YunaKoharuChan____꧂3(n+4)=21 what does n =?
Answer:
3.
Step-by-step explanation:
3(n + 4) = 21
3n + 12 = 21
3n = 21 - 12 = 9
n = 3.
Answer:
n = 3
Step-by-step explanation:
Given
3(n + 4) = 21 ( divide both sides by 3 )
n + 4 = 7 ( subtract 4 from both sides )
n = 3
Does anybody know the answer to this question Im having lots of problems
This is the same as writing [tex]3^9[/tex]
====================================================
How to get that answer:
The lowest height is 3^8, and the highest point is 3 times that value.
We can think of that second "3" as really 3^1. This is because x^1 = x for any real number.
Multiply 3^8 and 3^1 using the rule that a^b*a^c = a^(b+c). We add the exponents together.
Therefore, 3^8*3^1 = 3^(8+1) = 3^9
Side notes:
3^8 = 6,5613^9 = 19,683Answer:
3^9
Step-by-step explanation:
3 * 3^8
3^1 * 3^8
3^1+8
= 3^9

Step-by-step explanation:
At the Galapagos Islands, Dr. Owen finds 102 giant tortoise eggs that he brings back to his research center to be hatched in safety. At the research center, six of the eggs hatch, and the hatchlings are placed in a nursery. Dr. Owen places equal but unknown numbers of the remaining eggs in eight different labs.
Which of the following equations best represents this situation?
Question 5 options:
8x-6=102
102x=8-6
6x+8=102
8x=102-6
Answer:
8x-6=102
Step-by-step explanation:
8x the remaining eggs in 8 different labs and the 6 that are placed in the lab and the total is 102 so 8x-6=102

What is the total payment
required to pay off a promissory
note issued for $500.00 at 10%
ordinary interest and a 180-day
term?
Answer:
the total payment need to pay is $525
Step-by-step explanation:
Given that
The amount at promissory note issued is $500
The rate of interest is 10%
And, the time period is 180 days
So, the total payment included is
= $500 + ($500 × 10% × 180 days ÷ 360 days)
= $500 + $25
= $525
hence, the total payment need to pay is $525
[tex]find \: the \: area \: of \: cylinder \: \\ \\ height \: = 4cm \\ \\ base \: radius \: = 6cm \\ \\ [/tex]
Answer:
Curved Surface Area = 48π cm² (≈ 150.72 cm²)
Total Surface Area = 120π cm² (≈ 376.8 cm²)
Step-by-step explanation:
GIVEN :-
Height of cylinder = 4 cmBase radius = 6 cmTO FIND :-
Area of cylinderGENERAL FORMULAES TO BE USED IN THIS QUESTION :-
Curved Surface Area of cylinder = 2πrh
Total surface Area of cylinder = 2πrh + 2πr² = 2πr(h + r)
SOLUTION :-
Curved Surface Area of cylinder = 2×π×6×4 = 48π cm² ≈ 150.72 cm²
Total Surface Area of cylinder = 2×π×6(4 + 6) = 120π cm² ≈ 376.8 cm²
Mara drew this net to find the surface area of a triangular prism. Which is the surface area of the triangular prism?
A.312
B.402
C.372
D.492
(Square cm)
Answer:
C.372
Step-by-step explanation:
A prism is a three dimensional shape with two identical shapes facing each other known as bases.
A triangular prism has two triangular bases and three rectangle.
From the net attached:
Area of triangle 1 = area of triangle 2 = (1/2) * base * height = (1/2) * 10 cm * 12 cm = 60 cm²
Area of rectangle 1 = Area of rectangle 2 = length * width = 13 cm * 7 cm = 91 cm²
Area of rectangle 3 = base * height = 10 cm * 7 cm = 70 cm²
Total surface area = Area of triangle 1 + Area of triangle 2 + Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3
Total surface area = 60 + 60 + 91 + 91 + 70 = 372 cm²

Answer:

Step-by-step explanation:
The function V=25000\left(0.82\right)^tV=25000(0.82) t models the depreciation of the value of a new car that originally cost $\text{25,000}25,000. VV represents the value of the car and tt represents the time in years from the time the car was purchased. What is the value of the car after 6 years?
Answer:
V = 7,600.17
Step-by-step explanation:
Given:
V=25000(0.82)^t
Where,
V = value of the car
t = time in years
Find V when t = 6
V = 25,000(0.82)^t
= 25,000(0.82)^6
= 25,000(0.304006671424)
= 7,600.1667856
Approximately
V = 7,600.17

Question:
What’s the volume ?
Answer:
Volume: 8663.2
Area : 392
Step-by-step explanation:
The formula for volume is length times width times height (L x W x H)
So
28 x 28 = 784 x 22.1 = 17326.4 (Crazy right) But this is not the answer. A triangle is half of a Square so we divde by 2
17326.4 / 2 = 8663.2
The Volume is 8663.2
And if you are looking for the Area it's 392
