Step-by-step explanation:
Geometric sequences are of the form a * b^x, where a and b are real constants.
We have a * b⁴ = 234 and a * b⁶ = 104.
Dividing the second equation by the first,
we get b² = 4/9, so b = 2/3.
When x = 4, a * b⁴ = 234.
=> a * (2/3)⁴ = 234, a = 1184.625
Hence the explicit rule
is a(n) = 1184.625 * (2/3)^n.
Answer:
Hence the explicit rule is a(n) 1184.625 *(2/3)^n.
A skateboard costs $240. The sales tax on the skateboard is $12. What the percent of the sales tax?
Answer:
5%
Step-by-step explanation:
12 divided by 240 is 0.05, which is a PERCENTAGE FRACTION (as I like to call it).
This means that you can easily make this into a percentage.
Example Percentage Fractions:
A whole number, like 1 for example, is 100% or more.
The number 1 is 100%, and 2 is 200% and 4.25 is 425%
But since 12 divided by 240, in this problem, is 0.05, it is 5%.
Example are:
0.08 is 8%
0.02 is 2%
0.43 is 43%
0.79 is 79%
It's pretty simple.
Sorry if this isn't very good, I'm not a good teacher XD

Which equation is equivalent to 12crt x+15 = 36?
Answer:
Step-by-step explanation:
[tex]12\sqrt[3]{x+15} = 36\\\\[/tex]
Divide both sides by 12
[tex]\frac{12\sqrt[3]{x+15}}{12}=\frac{36}{12}\\\\ \sqrt[3]{x+15} =3[/tex]

What Is The Estimated Weight Of Three Containers Weighing 1.656 kg each? (Math 5 Quarter 2, Week 5) I Need A Nice And Clear Answer
Answer:
[tex]Estimate = 5.0kg[/tex]
Step-by-step explanation:
Given
[tex]Weight = 1.656kg[/tex]
Required
Determine the estimated for 3 containers
Since the weight of all containers are the same, we simply multiply the given weight by the number of containers.
i.e.
[tex]Estimate = Number\ of\ containers * Weight\ of\ each[/tex]
[tex]Estimate = 3 * 1.656kg[/tex]
[tex]Estimate = 4.968kg[/tex]
[tex]Estimate = 5.0kg[/tex] --- approximated
So, the estimated weight is 5.0kg

+
Answer:
Step-by-step explanation:
∑ angles = 360°
2x + 90 + x + 3x = 360
6x = 270
x = 45°
:::::
∠A = ∠B, so AD and BC are parallel.
Help please
Look at picture
Supplementary angles
Answer:
Both are supplementary angles so
(2x-3) +71 = 180
2x - 3= 180 - 71 = 109
2x = 109 +3 =112
X = 112 / 2= 56
x = 56

25 times number of pants purchased plus 10 times number of shirts purchased must be less than 500
Mr Morris built a fence to enclose his yard he put 3/4 of the fence on Monday on Tusday he put up 1/6 of the fence and on wensday he put up the rest of the fence what portion of the fence on Wensday
Answer:Portion put up on Wednesday =1/12
Step-by-step explanation:
Since we are dealing with fraction
Let the total fence = 1 whole
such that fence put up on Monday = 3/4
and fence he put p on Tuesday = 1/6
Since he put up the rest on Wednesday, To find the portion put up we have that
Portion put up on Wednesday =Total portion of fence - ( Portion put up on Monday and Tuesday)
=1- ( 3/4 + 1/6)
= 1- 18+ 4/ 24
=1- 22/24
= 2/24
Portion put up on Wednesday =1/12

Dupa ce a cheltuit in prima zi 0.4 dintro suma de bani iar in a doua zi o treime din ceea ce ia ramas. Damian mai poate cheltui 60 lei. Ce suma a avut initial?
Răspuns:
150 Lei
Explicație pas cu pas:
Fie suma inițială = x
Cheltuieli în prima zi = 0,4x
Cheltuieli pentru a doua zi = 1/3 (x - 0,4x)
Suma rămasă = 60
x = 0,4x + 1/3 (0,6x) + 60
x = 0,4x + 0,2x + 60
x = 0,6x + 60
x - 0,6x = 60
0,4x = 60
x = 60 / 0,4
x = 150 Lei

Kaitlyn solved the equation 5y=15 and found answer to be y=75. In complete sentence or two, explain what kaitylns error was? What did she do wrong? What is correct answer? Show your work and explain reasoning
Answer:
3
Step-by-step explanation:
Instead of dividing, Kaitlyn multiplied both sides by 5. Divide both sides by 5 to get the y by itself and you get 3
Answer:
y=3
Step-by-step explanation:
She assumed y=75, but if y=75 then you would multiply 75×5 and that doesn't equal 15. To find y you would need to divide 5 from both sides. Therefore 15÷5 would be equal to y=3. Hope this helps!

A boat travels 336 miles in 67
hours (with a constant speed).
How far can it travel in 58 hours
(with the same speed)?
Answer:
290.87 miles
Step-by-step explanation:
336 miles - 67 hours
x miles - 58 hours
Cross multiply
67x = 336 x 58
67x = 19488.
Divide both sides by 67
x = 19488/67
x = 290.87 miles
The Johnsons are having a family reunion and they want to order T-shirts. 36 people will be
attending the reunion. There will be twice as many children as adults at the reunion. Set up a
system of equations that represents the numbers of adults and children that are attending the
reunion and solve the system to figure out how many adult and child T-shirts they need to buy.
(hint: let a=the number of adults, and c=the number of children)
Answer:
a= 12, c= 24
The Solution:
a=?, c=?, No. of people attending=36
since c is twice as many as a, a= 2a
a + 2a= 36
3a= 36
(divide both sides by 3)
3a/3=36/3
a= 12
therefore, a= 12
since c is equals to 2a,
2a= 2(12)
2a= 24
therefore, c= 24
