-]Kala’s fish tank has 16 liters of water in it. She plans to add 4 liters per minute until the tank has more than 36 liters. What are the possible numbers of minutes Kala could add water?
-]Use t for the number of minutes.
-]Write your answer as an inequality solved for t.
Answer:
I will ask a freind if they know
Step-by-step explanation:
Answer:
t > 5
Step-by-step explanation:
Time : liters
[tex]\left[\begin{array}{ccc}0&16\\1&20\\2&24\\3&28\\4&32\\5&36\\6&40\end{array}\right][/tex]
We can see using the table that at 5 minutes, there would be 36 liters of water in the tank. Since Kala is going to keep filling the tank until there is more than 36 liters, the inequality would be t > 5.

smeone invests £800 at a rate of 2% simple interest per year. Work out the amount of interest she receives after three years.
Answer:
£48
Step-by-step explanation:
I=Prt
I=(800)(0.02)(3)
I = 48
Answer:
the simple interest earned was £48.
Step-by-step explanation:
the appropriate simple interest formula is i = prt, where r is the annual interest rate as a decimal fraction. Here, with prt = (£800)(0.02)(3 yr), we find that the simple interest earned was £48.
If angle DCA measures 40 degrees, what does angle ACB measure?
*see attachement for the diagram that is being referred to
Answer:
m<ACB = 50°
Step-by-step explanation:
From the diagram, <DCB is a right angle = 90°
Therefore:
m<DCA + m<ACB = 90° (complementary angles)
m<DCA = 40° (given)
Thus:
40° + m<ACB = 90° (Substitution)
m<ACB = 90° - 40° (Subtraction property of equality)
m<ACB = 50°
No need for an explanation it is option
Answer:
152
Step-by-step explanation:
Trick question,
4x + 52 + 28 = 180
Then
You subtract 180 and 28 to get 152
In the evening, the temperature is 28 degrees. By midnight it has dropped 31 degrees lower. Between midnight and 4 am it goes down 6 more degrees. Then, by 9 am, the temperature goes up 30 degrees. What is the temperature at 9 am?
Answer: 21 degrees
Step-by-step explanation:
In the evening, the temperature is 28 degrees and by midnight it has dropped 31 degrees lower, the temperature by midnight will be:
= 28° - 31°
= -3°
Between midnight and 4 am it goes down 6 more degrees. The temperature by 4am will be:
= -3° - 6°
= -9°
Then, by 9 am, the temperature goes up 30 degrees, the temperature at 9 am will then be:
= -9° + 30°
= 21°

Martha was making apple tarts. She added 1/2 cup of sugar in the beginning. Later, she added another 1/4 cup of sugar. Martha estimated that she added about 1/6 cup of sugar in all. Is Martha's estimate reasonable?
Answer: her answer is NOT reasonable because 1/2 is bigger that 1/6. The real addition to 1/2 and 1/4 is 3/4.
Step-by-step explanation:
1/2 is 2/4 and 1/4 stays the same because it is the common denominator
Add them and you get 3/4

I need the answer to both pictures!!!!!!!
Answer:
60° 60° 60°
60°
Step-by-step explanation:
In any triangle, the sum of its interior angles is 180°, and 60+60+60=180.
As for the other question, we can see that angle5=angle1, and angle6=angle2, due to the parallelism of the lines.
Angle5+angle6=180°, therefore
Angle6=180-120=60°=angle2
Look at the picture.
Answer:
(4, 8) where =(x, y)
Step-by-step explanation:
x + 4(-x + 12) = 36
x -4x + 48 = 36
-3x = -12
x = 4
4 + 4y = 36
4y = 32
y = 8

Answer:
Area = 52√3
A
Step-by-step explanation:
Remark
This is a trapezoid. The formula for a trapezoid is Area = 1/2 (b1 + b2)* h/2
Givens
b1 = 11
b2 = 15
h = 4*√3
Solution
Area = 1/2 (15 + 11 )*4*√3
Area = 1/2(26)*4√4
Area = 13 * 4√3
Area = 52√3
Due: Today Raven told Micah the perimeter of the swimming pool was 35 feet, the dimension of the pool were 5 ft by 7 ft. Micah said the perimeter was 24 feet. Who is correct? Justify your answer.
Answer: Micah
Step-by-step explanation:
Given
Raven told Perimeter of the swimming pool is [tex]35\ ft[/tex]
Micah said Perimeter is [tex]24\ ft[/tex]
The actual dimension of the swimming pool is [tex]5\ ft\times 7\ ft[/tex]
Perimeter is given by [tex]2(l+w)[/tex]
Using this, the perimeter is
[tex]\Rightarrow P=2(5+7)\\\Rightarrow P=2\times 12=24\ ft[/tex]
[tex]\therefore[/tex] Micah statement is correct.

Step-by-step explanation:
In a survey of 1000 eligible voters selected at random, it was found that 100 had a college degree. Additionally, it was found that 80% of those who had a college degree voted in the last presidential election, whereas 56% of the people who did not have a college degree voted in the last presidential election. Assuming that the poll is representative of all eligible voters, find the probability that an eligible voter selected at random will have the following characteristics. (Round your answers to three decimal places.)
Answer:
A. 8%
B. 39.6%
C. 58.4%
D. 41.6%
Step-by-step explanation:
Computation to determine the probability of eligible voter selected at random
First step is to Draw up a contingincy table which will include Rows = Degree/No degree
and Columns= Vote/Not vote
..............Vote..No vote
Degree 80...20...100
(80%*100=80)
(100-80=20)
No Degree 504..396..900
(1000-100=900)
(56%*900=504)
(504-900=396
Totals 584..416...1000
(80+504=584)
(20+396=416)
(900+100=1,000)
Summary
..............Vote..No vote
Degree 80...20...100
No Degree 504..396..900
Total Totals 584..416...1000
A. Calculation to determine the probability of The voter had a college degree and voted in the last presidential election.
P = 80/1,000
P=0.08*100
P=8%
Therefore the probability of The voter had a college degree and voted in the last presidential election will be 8%
B. Calculation to determine the probability of The voter did not have a college degree and did not vote in the last presidential election.
P =396/1000
P=0.396*100
P=39.6%
Therefore the probability of The voter did not have a college degree and did not vote in the last presidential election will be 39.6%
C. Calculation to determine the probability if The voter voted in the last presidential election.
P = 584/1,000
P=0.584*100
P=58.4%
Therefore the probability if The voter voted in the last presidential election will be 58.4%
D. Calculation to determine the probability if The voter did not vote in the last presidential election.
P = 416/1000
P=0.416*100
P=41.6%
Therefore the probability if The voter did not vote in the last presidential election will be 41.6%

All the lines in the figure intersect at point P.
What is the measure of ZKPL?
Answer:
angle KPL = 70 degree
Step-by-step explanation:
A straight line will equal 180 degrees
To find angle IPN, add angles NPM (60) and IPJ (50) and subtract the number from the straight line (180)
60 + 50 + IPN = 180
110 + IPN = 180
IPN = 70
IPN is a congruent angle to KPL
Congruent means they will equal the same
IPN = KPL
70 = 70
We can check our work by adding NPM (60) and KPL (70) and subtracting the sum from the straight line (180). Our answer should be the same as IPJ (50) as MPL is congruent to IPJ
60 + 70 + MPL = 180
130 + MPL = 180
MPL = 50
