Answer:
a(5)=-48
Step-by-step explanation:
I think u r confused
this sequence is geometric not arithmetic
HOw we know that ??
when we get a common difference that must Be equal
d=6+3=9 not equal to d=-12-6=-18
So it is not arithmetic
but when we get the common ratio that also must be equal
r=6/-3=-12/6=24/-12=-2 equal
So it is geometric
By using this equation:
a(n)=a*r^(n-1)
and we have a=-3 , r=-2
Then a(n)=-3*(-2)^(n-1)
To get the next term:
a(5)=-3*(-2)^(5-1)
a(5)=-3*(-2)^(4)
a(5)=-3*16=-48
I really hope this helps <3

If triangle JKL~ Triangle MKN, find the value of x
Answer:
x = 14
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{KL}{KN}[/tex] = [tex]\frac{JL}{MN}[/tex] , substitute values
[tex]\frac{32}{12}[/tex] = [tex]\frac{3x-2}{x+1}[/tex] ( cross- multiply )
12(3x - 2) = 32(x + 1) ← distribute both sides
36x - 24 = 32x + 32 ( subtract 32x from both sides )
4x - 24 = 32 ( add 24 to both sides )
4x = 56 ( divide both sides by 4 )
x = 14
For the given triangles ΔJKL ≈ ΔMKN, the value of x is, 4
What is similarity of triangles?Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"
Given that,
One right angle triangle, ΔJKL
one segment MN which is intersecting sides KJ & KL
ΔJKL has one similar triangle inside, which is ΔMKN
Triangle ΔJKL and ΔMKN are similar,
So, we can say ΔJKL ≈ ΔMKN
And it is known that
for similar triangles, ratio of lengths of sides are equal for similar triangles
so, KN/MN = KL/JL
⇒ (X + 1)/12 = (3X -2)/32
⇒ 32X + 32 = 36X - 24
⇒ 32 + 24 = 36X - 32X
⇒ 56 = 14X
⇒ X = 4

A local restaurant served 124 cups of pancake mix every hour it takes 1 1/4 cups of mix to make one pancake the pancakes are all equal in size about how many pancakes can the restaurant make in two hours
Answer: The restaurant can make 199 pancakes in two hours.
Step-by-step explanation:
Given: Total number of cups of pancake mix used in 1 hour = 124
Mix required for each pancake = [tex]1\dfrac14=\dfrac{5}{4}[/tex]
Number of cups of pancake mix used in 2 hours = 2 x 124 = 248
Number of pancakes made = (Number of cups of pancake mix used in 2 hours ) ÷ (Mix required for each pancake )
[tex]=248\div\dfrac54\\\\=248\times\dfrac45\\\\= 198.4\approx199[/tex]
Hence, the restaurant can make 199 pancakes in two hours.

One way to express exponential form is to use
y = a*b^x
where 'a' is the initial value and 'b' is linked to the growth rate.
Since we're told 34 bees are there initially, we know a = 34.
Then after 4 days, we have 48 bees. So we can say,
y = a*b^x
y = 34*b^x
48 = 34*b^4
48/34 = b^4
24/17 = b^4
b^4 = 24/17
b = (24/17)^(1/4)
b = 1.090035
Which is approximate.
The function updates to
y = a*b^x
y = 34*(1.090035)^x
------------------------
As a way to check to see if we have the right function, plug in x = 0 and we find:
y = 34*(1.090035)^x
y = 34*(1.090035)^0
y = 34*(1)
y = 34
So there are 34 bees on day 0, ie the starting day.
Plug in x = 4
y = 34*(1.090035)^x
y = 34*(1.090035)^4
y = 34*1.4117629
y = 47.9999386
Due to rounding error we don't land on 48 exactly, but we can round to this value.
We see that after 4 days, there are 48 bees.
So we confirmed the correct exponential function.
------------------------
At this point we can find out how many bees there are expected to be after 20 days.
Plug in x = 20 to get
y = 34*(1.090035)^x
y = 34*(1.090035)^20
y = 190.672374978452
Round to the nearest whole number to get 191.
There are expected to be roughly 191 bees on day 20.

the length of a rectangular mat is twice its breath.if its length is 50 cm find its area and perimeter
Answer:
L = 2W
If L = 50cm
then
w= 25cm
Area = L*W= 50*25
Area= 1250 cm^2
Perimeter
P = 2(L+W)
P= 2 (50+25)
P = 150cm
A garden has the dimensions of 5x4 in feet. The gardener wants to expand her garden to 56 square feet. She wants to add the same distance (x) to each side. What is the value of x. Must show work for credit. *
Answer:
2 feet
Step-by-step explanation:
If we were to add the same amount to each dimension then the ratio would be the same, meaning that the length will always be one more than the width. Therefore, the two consecutive numbers that when multiplied equal 56 are 6 and 7.
7 * 6 = 56 square feet
This means that we would be adding 2 feet to each side.

I already got that the expression that represents the expenses of the fundraiser would be -5x+100. But I was kinda confused about the other ones :-/ Any help would be appreciated (-:
Answer:
10x>5x+100
Step-by-step explanation:
it says expression not equations so its < , >,
The profit would be on one side and the expenses on the other
No negatives
so it would be 5 times X (the amount of shirts) plus the base fee of $100
and they plan on selling it for 10$ each so (10x) is the profit
X = number of shirts

At the end of the year, Close made the current year on mark down to make Room for next year models. One particular model had a sticker price of $28,640 when it was new. After being marked down, the price is now $27,208. What What is the percent of decrease in the price of the car
Answer: 5%.
Step-by-step explanation:
Given data:
Old price = $28,640
New price = $27,208
Solution:
Percentage of decrease
= old price - new price / old price * 100
= $28,640 - $27,208 /. $28,640 * 100
= $1432/$28,640*100
= 0.05*100
= 5%.
The percentage of decrease for the car is 5%.
There is a sale at your favorite clothing store. They have their jeans priced at $49.99 with a extra 20% off. How much will you pay for three pairs of jeans, not including tax? Exlpain how you got your answer.
Answer: You need to pay $119.98 for three pairs of jeans.
Step-by-step explanation:
Market price of 1 jeans = $49.99
Discount percent = 20% = 0.20
Market price for 3 jeans = 3 x ($49.99)
= $ 149.97
Discount price = 20% of (Market price for 3 jeans )
= .0.20 x ($149.97)
= $ 29.99
Price of 3 jeans after discount = (Market price for 3 jeans ) - ( Discount price)
= $ (149.97 - 29.99)
= $ 119.98
Hence, you need to pay $119.98 for three pairs of jeans.

Answer:
367.62 in³
Step-by-step explanation:
The volume of a sphere is V = (4/3)πr³.
Here, that volume of the whole sphere is V = (4/3)(3.14)(5.6 in)³, or
V = 735.25 in³
A 'hemisphere' is half a sphere. Thus, the volume of each hemisphere shown here is
735.25 in³

ΔABC is similar to ΔAXY by a ratio of 4:3. If BC = 24, what is the length of XY? triangles ABC and AXY that share vertex A where point X is between points A and B and point Y is between points A and C XY = 18 XY = 32 XY = 6 XY = 8
Answer:
[tex]XY = 18[/tex]
Step-by-step explanation:
Given
[tex]ABC:AXY = 4 : 3[/tex]
[tex]BC = 24[/tex]
Required
Find XY
Represent BC and XY as a ratio;
[tex]BC : XY = 24 : xy[/tex]
Recall that:
[tex]ABC:AXY = 4 : 3[/tex]
Equate both ratios;
[tex]24 : xy = 4 : 3[/tex]
Convert to fractions
[tex]\frac{24}{xy} = \frac{4}{3}[/tex]
Cross Multiply
[tex]xy * 4 = 24 * 3[/tex]
[tex]xy * 4 = 72[/tex]
Divide through by 3
[tex]xy * 4/4 = 72/4[/tex]
[tex]xy = 18[/tex]
Hence:
[tex]XY = 18[/tex]
Answer:
XY = 18

Of the 150 students that attended the science camp, 82 were sixth graders. Marco says that less than half of the campers were sixth graders. Is he correct? Tell why or why not. Use a benchmark percent to support your answer.
Answer:
Incorrect
Step-by-step explanation:
150 students are 100%,
82 students are x%
(82*100)/150=54,67%, so that is more than half of all students
Answer:
Marco is NOT correct
Step-by-step explanation:
150 / 2 = 75
so more than half of the students were 6th graders
55% of students were 6th graders, that's my benchmark but I'm not really sure.
