Find the sum of the first 90 terms of the sequence –4, –1, 2, 5, 8, ...
a.
11654
c.
11656
b.
11657
d.
11655
Answer:
D. 11655
Step-by-step explanation:
First find the 90th term:
a90=a1+(n−1)d
= -4+89(3)=263
Then find the sum:
Sn = n(a1 + an) / 2
S90 = 90 (-4 + 263) /2
S90 = 23,310/2
S90 = 11,655
I need help please what’s the answer?
Answer:
The terms combine into 9x + 17
Step-by-step explanation:
What you need to realise here is that the brackets don't serve any real purpose, as there's no operation being done on their contents as a whole. With that in mind we can simply drop the brackets and group like terms:
(4x + 8) + (5x + 9)
= 4x + 8 + 5x + 9
= 4x + 5x + 8 + 9
= 9x + 17
So the terms combine into 9x + 17

Please help! Tysm! Picture of figure is attached.
Reasoning in the diagram at the right, K, L, and M are the midpoints of the sides of AABC. The vertices of the three small purple triangles are the midpoints of the sides of AKBL, AAKM, and AMLC. The perimeter of AABC is 24 cm. What is the perimeter of the shaded region?
Step-by-step explanation:
Notice that KM = 0.5BC, KL = 0.5AC
and ML = 0.5AB. Therefore the perimeter of triangle KLM is half of the perimeter of triangle ABC. => 0.5 * 24cm = 12cm.
Each of the 3 purple triangles have perimeters which are 1/4 of the perimeter of triangle ABC. (Their vertices are midpoints of midpoints => 1/2 * 1/2)
Perimeter of 3 small purple triangles
= 3 * [24cm * (1/4)]
= 3 * 6cm = 18cm.
Hence Total perimeter of shaded parts
= 12cm + 18cm = 30cm.
What is the final amount if 943 is decreased by 13% followed by a further 6% decrease?
Answer:
771.18
Step-by-step explanation:
The Amount given is 943
13% of amount will be = 943 x 13%
=
Decreasing 13% from 943 we get = 943-122.59
=820.41
Now the ammount = 820.41
for finding the final amount
find 6% of amount (820.41) we get = 820.41x 6%
=
Decreasing 6% from 820.41 we get final amount= 820.41- 49.23
=771.18
so the final amount is 771.18
Use the number line to find each measure
Answer:
ST = 3 units
Step-by-step explanation:
From the number line attached in the picture,
Distance of S from 0 = 7 units
Distance of T from 0 = 4 units
Therefore, distance between S and T = 7 - 4
ST = 3 units
[Note : Length of a segment is always positive so ST can't be negative]

Step-by-step explanation:
if thrice my age 6 years ago be subtracted from twice my present age the result is present age then my present age is what
Answer:
9 years
Step-by-step explanation:
Let the present age = x
Age 6 years ago = x - 6
Thrice my age 6 years ago = 3*(x -6) =3x - 3*6 = 3x - 18
Twice my present age = 2 *x = 2x
Thrice my age 6 years ago be subtracted from
twice my present age = 2x - (3x - 18)
2x - (3x - 18) = x
2x - 3x + 18 = x
-x + 18 = x {Add x to both sides}
18 = x + x
18 = 2x {Divide both sides by 2}
18/2 = x
x = 9 years
