An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.
Find the term of the sequence that has value -93. please answer asap.
Answer:
50th term
Step-by-step explanation:
Second term, a + d = 3
Tenth term, a + 9d = -13
a + d = 3 (1)
a + 9d = -13 (2)
Subtract (1) from (2) to eliminate a
9d - d = -13 - 3
8d = -16
d = -16/8
d = -2
Substitute d = -2 into (1)
a + d = 3 (1)
a + (-2) = 3
a - 2 = 3
a = 3 + 2
a = 5
Find the term of the sequence that has value -93.
nth term = a + (n -1)d
-93 = 5 + (n - 1) -2
-93 = 5 + (-2n + 2)
-93 = 5 - 2n + 2
-93 = -2n + 7
-93 - 7 = -2n
-100 = -2n
n = -100/-2
n = 50
50th term = -93

Answer:
b)30 boys c)1425 beats
Step-by-step explanation:
Answer:
Step-by-step explanation:
b and g are the number of boys and girls, respectively.
b:g = 3:4
b = 3x, g = 4x
3x+4x = 70
x = 10
There are 30 boys.
:::::
(380 beats)/(4 minutes) = (380/4 beats)/minute = (95 beats)/minute
15 minutes × (95 beats)/minute = 1425 beats

Paddy and Anna each invest $2000 for 5 years.
Paddy earns simple interest at a rate of 1.25% per year.
Anna earns compound interest at a rate of r% per year.
At the end of 5 years, Paddy's investment is worth the same as Anna's investment.
Calculate the value of r.
Answer: r= 1.22
Step-by-step explanation:
Formula for amount with simple interest = [tex]P(1+rt)[/tex]
, where
P= principal value , r= rate of interest , t = time.
Given: P= $2000, t= 5 years, r= 1.25% = 0.0125
[tex]A=2000(1+0.0125\times5)\\\\=2000(1.0625)=2125[/tex]
Formula to compute compound amount : [tex]P(1+r)^t[/tex]
[tex]=2000(1+r)^5[/tex]
When both have same worth then
[tex]2000(1+r)^5=2125\\\\\\ (1+r)^5=\dfrac{2125}{2000}\\\\\\ (1+r)^5=1.0625[/tex]
taking log on both sides , we get
[tex]5\ln (1+r)=\ln 1.0625\\\\\\ 5\ln (1+r)=0.0606246\\\\\\ \ln (1+r)=0.012125\\\\\\ 1+r=e^{0.005266}\\\\\\ 1+r=1.0122\\\\ r=0.0122\\\\ \\ r=1.22\%[/tex]
Hence, Value of r= 1.22

dimes. By following the steps below, determine the number of nickels, x, and the
number of dimes, y, that Arianna has.
Answer:
X=3
Step-by-step explanation:
0.05(4x) + 0.1x = 0.90
0.2x + 0.1x = 0.90
0.3x = 0.90
x = 3

Write a system of equations or inequalities (whichever is most appropriate for the given context) for the scenario below. Be sure to precisely define the variables.
YOU DO NOT NEED TO SOLVE THE SYSTEM! JUST WRITE ONE!
Scenario:
Charlie the Chocolatier mixed chocolate chips and pretzels to create 36 pounds of his holiday blend that sells for $6.00 per pound. The chocolate chips cost $7.00 per pound and the pretzels cost $4.00 per pound. How many pounds of each did he use?
Answer:
x + y = 36 (1)
7x + 4y = 216 (2)
Step-by-step explanation:
Quanrity of Holiday blend = 36 pounds
Cost per pound of the blend = $6.00
Cost of chocolate chips = $7.00 per pound
Cost of pretzels = $4.00 per pound
Let
Pounds of chocolate chips = x
Pounds of pretzels = y
x + y = 36 (1)
7x + 4y = 36 × $6.00
7x + 4y = 216 (2)
The system of equation is
x + y = 36 (1)
7x + 4y = 216 (2)

The sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex], option C is correct.
What is Sequence?Sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
The given series is -5+(-1)+3+7+11
The sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex]
Now let us check by plugging j values from 1 to 5
When j =1,
4(1)-9= -5
When j =2
4(2)-9 = -1
when j=3
4(3)-9= 3
Hence, the sigma notation of the given series is [tex]\sum _{j=1}^5\:\left(4j-9\right)[/tex], option C is correct.

plss help it's urgentt
Answer:
1. 25
Step-by-step explanation:
First, you need to place the numbers in ascending order, meaning from smallest to largest.
You calculate the range by taking the largest number and subtract the smallest from it, so in this case: 42-17 = 25
Mean (average), just add the numbers up and divide by how many numbers you have
III. Once you find the Mean and you placed them in order from smallest to largest, you can find this answer
Median (middle) - which number is in the middle so after you place them in order which is in the middle if you have an odd number of marks, but since you have 12 marks then take the 2 center numbers, add them up, and divide by 2, in other words, get the mean of the middle numbers and that will give you the median in this problem
Mode, which number appears the most times repeated
Answer:
i. 25 (range = the difference between the highest and lowest number)
ii. 30.41 (mean = sum of all numbers divided by the how many numbers there are)
iii. 6
iv. 35
v. 35

two numbers have the ratio of 4:7 if their sum is 143 what are the numbers?
1.kind of proportion
2.write the proportion
3.first number answer
4second number answer
help me plss!
Answer:
52:91
Step-by-step explanation:
To find a ratio value you need to think of it more as two numerators that together equal one whole. 4+7 is 11 so that would be the denominator. If the sum is 143, then we divide by 11 since one number is 4/11s of 143, and the other is 7/11s of 143. 143/11=13
now we multiply both:
4(13)=52
7(13)=91
Check:
91+52=143
52/91 simplifies to 4/7 or 4:7
