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.

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]

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/hStep-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 kmWe have following equations:
r(8/3 + t) = 17(12 - r)t = 27Simplify the equations:
r(8/3 + t) = 17 ⇒ rt + 8/3r = 17(12 - r)t = 27 ⇒ 12t - rt = 27Add up the equations and solve for r:
rt + 8/3r + 12t - rt = 448/3r + 12t = 44r = 16.5 - 4.5tSubstitute r into second equation:
(12 - 16.5 + 4.5t)t = 274.5t² - 4.5t = 279t² - 9t - 54 = 0Solving we get
t = 3 hFind r:

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.
