Find the 96th term of the arithmetic sequence-30,-32,34

Answers

Answer:

a = -30

d = -32 - (-30) = -2

n = 96

So, using A.P. formula-

Tn = a + (n-1) d

T96 = -30 + (96-1) -2

T96 = -30 + (95) -2

T96 = -30 - 190

T96 = -220

Karim began his day by drinking 1 1/8

cups of milk at breakfast. By the end of the day, he drank a total of 2 2/3

cups of milk.

Which equation and solution correctly represent the amount of milk in cups, m , Karim drank after breakfast?

Answers

Answer:

A. 1⅛ + m = 2⅔

[tex] m = 1\frac{13}{24} [/tex]

Step-by-step explanation:

Cups of milk at breakfast = 1⅛

Cups of milk after breakfast = m

Total cups of milk by the end of the day = 2⅔

Thus:

Total cups of milk by the end of the day = cups of milk at breakfast + cups of drink after breakfast

Therefore:

1⅛ + m = 2⅔ (equation)

Solve for m

Subtract 1⅛ from each side

m = 2⅔ - 1⅛

Convert to improper fraction

m = 8/3 - 9/8

m = (64 - 27)/24 = 37/24

[tex] m = 1\frac{13}{24} [/tex]

Liliana used 4 dark power crystals to raise 14 zombie soldiers. She wants to know how many zombie soldiers (z) left parenthesis, z, right parenthesis she can raise with 10 dark power crystals.

Answers

Answer:

So.. Liliana used 4 crystals to race 14 zombie soldiers.

14 / 4 = 3.5. She can race 3.5 zombie soldiers if she uses 1 crystal. So, all you need to do it multiply 3.5 by 10 and you end up with 35.

So, Liliana is able to race 35 zombie soldiers with 10 power crystals.

Daniela painted a photo that was 4/5 afoot by 1 7/8 of afoot. What was the area?

Answers

Answer:

[tex]\frac{3}{2}[/tex] square feet

Step-by-step explanation:

The dimensions of the photo is 4/5 by 1 7/8 of a foot.

But,

1 7/8 = [tex]\frac{15}{8}[/tex] feet

So that,

length of the photo = [tex]\frac{15}{8}[/tex] feet

width of the photo = [tex]\frac{4}{5}[/tex] feet

The area of the photo = length x width

= [tex]\frac{15}{8}[/tex] x [tex]\frac{4}{5}[/tex]

= [tex]\frac{60}{40}[/tex]

= [tex]\frac{3}{2}[/tex]

Area of the painted photo is [tex]\frac{3}{2}[/tex] square feet.

what operation do you use to convert from a larger measurement unit to a smaller measurement unit?explain why.

Answers

Answer:

Multiplication

Step-by-step explanation:

To convert from a larger unit to a smaller unit, we multiply. This is because the number will become greater since the unit is smaller.

Example:

1 m ⇒ ×100 ⇒ 100 cm

We use division when converting from a smaller unit to a larger unit since the number will become smaller as the unit becomes greater.

Example:

100 cm ⇒ ÷100 ⇒ 1 m

the thief with the stolen accordion has been traveling on a raft for 2 hour 40 minutes from Village Ivanovo toward Village Sosnovka. Aniskin immediately leaves Sosnovka in a motorboat and travels upstream toward the raft. Aniskin catches the thief 27 km from Sosnovka. Find the speed of the raft if the speed of the motorboat in still water is 12 km/h and the distance from Ivanovo to Sosnovka is 44 km.

Answers

Answer:

3 km/h

Step-by-step explanation:

Let the speed of raft (current) - rSpeed of motorboat - 12 km/hThe distance between villages - 44 kmLet the time spent by Aniskin - tThe time the thief was in travel = 2 hr 40 min + t = 2 40/60 + t = 3/8 + tThe distance the thief traveled = 44 - 27 = 17 km

We have following equations:

r(8/3 + t) = 17(12 - r)t = 27

Simplify the equations:

r(8/3 + t) = 17 ⇒ rt + 8/3r = 17(12 - r)t = 27 ⇒ 12t - rt = 27

Add up the equations and solve for r:

rt + 8/3r + 12t - rt = 448/3r + 12t = 44r = 16.5 - 4.5t

Substitute r into second equation:

(12 - 16.5 + 4.5t)t = 274.5t² - 4.5t = 279t² - 9t - 54 = 0

Solving we get

t = 3 h

Find r:

r = 16.5 - 4.5*3 = 3 km/h
