Answer: 238
Step-by-step explanation:
The formula to calculate the nth term of an arithmetic progression = a + (n-1)d
Based on the question,
a = -140
90th term = a + 89d = 483
We need to get the value of the common difference
a + 89d = 483
-140 + 89d = 483
89d = 483 + 140
89d = 623
d = 623/89
d = 7
Therefore 55term will be:
= a + (n - 1)d
= a + (55 - 1)d
= a + 54d
= -140 + 54(7)
= -140 + 378
= 238
the answer is D.

y = -5x+1
y = 3x – 2
Is (3.8) a solution of the system?
Answer: No, 3.8 is not a solution.
Step-by-step explanation:
Set -5x+1 equal to 3x-2
-5x+1=3x-2 subtract 3x making it -8x+1=-2 subtract one from both sides and get -8x=-3 divide by -8 and get -3/-8 which equals in decimal form 0.375
Check it
plug in 0.375 for X
-5(0.375)+1= -0.875
3(0.375)-2 = -0.875
It checks out ^_^

Answer:
C = 2πr
191.64 = 2 × 3.14 × r
r = 191.64/6.28
r = 30.51 yds
There are 300 students in the 9th grade and each student is assigned a locker. The 300 students start down the hall one at a time. The first student opens every locker. The second student closes all the lockers that are multiples of 2. The third student changes the lockers that are multiples of 3 (which means if a locker is closed, they open it. If the locker is open, they close it.) The fourth student changes all the lockers that are multiples of 4. This continues until the 300th student changes the 300th locker. Then, the principal walks down the hall, and changes all the lockers that are prime numbers. At the end, how many lockers will be closed?
Answer:
1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, 169, 196, 225, 256, 289

A quadrilateral in the coordinate plane has vertices (3, 2), (3,-4), (5,4), and (5,-2). What is the area, in square units, of the quadrilateral?
Answer:
4 square units
Step-by-step explanation:
the distance between (3, -4) and (5, -4) is 2, and the distance between (3, -2) and (5, -2) is also 2. since its a quadrilateral do 2x2 and you get 4.

At an intersection, the red light times are normally distributed
with a mean time of 3 minutes and a standard deviation of 0.25
minutes. Approximately what percent of red lights last between
2.5 and 3.5 minutes? (2 points)
32%
68%
Answer: The percent of red lights last between 2.5 and 3.5 minutes = 95.44% approx.
Step-by-step explanation:
Given: Mean time = 3 minutes
standard deviation = 0.25 minutes
The probability of red lights last between 2.5 and 3.5 minutes :-
[tex]P(2.5<x<3.5)\\\\=P(\dfrac{2.5-3}{0.25}<\dfrac{x-\mu}{\sigma}<\dfrac{3.5-3}{0.25})\\\\=P(-2<z<2)\\\\=2P(Z<2)-1\\\\=2(0.9772)-1\\\\=0.9544[/tex]
The percent of red lights last between 2.5 and 3.5 minutes = 95.44% approx.

In a class, everyone studies French or German, but not both languages. One third of the girls and the same number of boys study German. Twice as many boys as girls study French. Which of the total number of boys and girls in my class
Answer:
32
Step-by-step explanation:
Let the number of girls in the class be 3. Then the number of girls who study German is , as is
the number of boys who study German. So the number of girls who study French is 2 and the
number of boys who study French is 2 × 2 = 4.
Therefore the total number of boys and girls in the class is + + 2 + 4 = 8 and hence is a
multiple of 8. Of the options, only 32 is divisible by 8.

Which item is NOT printed on the bottom of a check?
a
check number
b
routing number
c
account number
d
date
Answer: d. Date
Step-by-step explanation:
Some of the information printed on the bottom of a check include the check number which is typically a security measure that is used in the identification of payment so as to prevent fraud.
The routing number also informs the bank where the funds for the check can be found.
The account number informs the person that collects the check about the account that the money is coming from.
We should note that the date is at the top of the check and one has to fill it himself or herself before giving the check to the recipient.
The expression (x^22) (x^7)^3 is equivalent to x^p. What is the value of p?
Answer:
x^87
Step-by-step explanation:
Multiplying x^22 and x^7 results in x^29.
Then we have:
(x^29)^3 = x^87
Recall that (a^b)^c = a^(bc) and that a^b*a^c = a^(b + c)
I need help now! Someone
Answer:
210
Step-by-step explanation:
Hi,
Split this up. Find the area of the rectangle first. To find the area of the rectangle, you need to multiply the L x W
So...
L x W
18 x 10
Area: 180
Now, you need to find the area of the two right triangles. For the first one, to find the area, it's 1/2bh.
So...
We know that 24 - 18 will give us the length of the right triangle. We get... 6 ft.
So...
1/2 (6) (5)
We get 15.
Since both right triangles are the exact same, the other right triangle will also equal 15ft.
Now, add all of the shapes.
15 + 15 + 180 = 210
Your total area is 210.
I hope this helps :)
