Tank B, which initially contained 80 liters of water, is being drained at a rate of 2.5 liters per minute. How many liters of water remain in the tank after 30 seconds?
Answer:
78.75 ?
Step-by-step explanation:
calculator..
The volume of water remain in the tank after 30 seconds is 78.75 liters.
The given parameters;
initial volume of water in Tank B, V₀ = 80 litersrate at which water is being drained, R = 2.5 liters per minute.time of water drain, t = 30 secondsThe amount of water drained after 30 seconds is calculated as follows;
[tex]V_1 =2.5 \ \frac{liters}{\min} \times \frac{1 \min}{60 \ s} \times 30 \ s\\\\V_1 = 1.25 \ liters[/tex]
The volume of water remain in the tank after 30 seconds is calculated as follows;
V₂ = V₀ - V₁
V₂ = 80 liters - 1.25 liters
V₂ = 78.75 liters
Thus, the volume of water remain in the tank after 30 seconds is 78.75 liters.

Given: angle 1 and angle 2 are complementary , angle 2 = 74 degrees Prove: angle 2 = 16 degrees
Answer:
I'm guessing the angle 1 is supposed to be 74 degrees and not angle 2?
Step-by-step explanation:
Either way. Complementary angles always have a sum of 90°. 74+16=90 so it checks out

Answer:
The entire race is 26.20 miles long.
Step-by-step explanation:
Given that:
Sam is 18.34 miles in the race.
This length represents the 70% of the entire length of the race.
Let,
x be the total length of the race.
70% of x = 18.34
[tex]\frac{70}{100}x=18.34\\[/tex]
0.7x = 18.34
Dividing both sides by 0.7
[tex]\frac{0.7x}{0.7}=\frac{18.34}{0.7}\\x=26.20[/tex]
Hence,
The entire race is 26.20 miles long.
There are 31 pink beads and 15 purple beads on Violet's necklace. What is the ratio of the number of beads to the number of pink beads?
Answer:
The ratio of number of purple beads to the number of pink beads is: 15:31
Step-by-step explanation:
Number of pink beads = 31
Number of Purple beads = 15
We need to find ratio of number of purple beads to the number of pink beads
So, The ratio of number of purple beads to the number of pink beads is:
Number of purple beads : Number of pink beads
15 : 31
Since it cannot be simplified further, So
The ratio of number of purple beads to the number of pink beads is: 15:31

H varies directly to the cube of c.
When H = 40, C = 2.
(a) Express H in terms of c.
Answer:
H in terms of c is H = 5c³.
Step-by-step explanation:
Given that:
H = 40 and c = 2
H varies directly to the cube of c.
Which means that,
H ∝ c³
Let,
k be the proportionality constant.
H = kc³
Putting H=40 and c=2
[tex]40=k(2)^3\\40=k(8)\\40=8k\\8k=40[/tex]
Dividing both sides by 8,
[tex]\frac{8k}{8}=\frac{40}{8}\\k=5[/tex]
Now,
H in terms of c.
H = 5c³
Hence,
H in terms of c is H = 5c³.

The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2,200 people enter the fair and $5,050 is collected. How many children and how many adults attended?
Given :
The admission fee at a small fair is $1.50 for children and $4.00 for adults.
On a certain day, 2,200 people enter the fair and $5,050 is collected.
To Find :
How many children and how many adults attended.
Solution :
Let, number of children and adults attended are c and a.
So, c + a = 2200 ....1)
Now, fair collected is given by :
1.5c + 4a = 5050 ....2)
Putting value of a from equation 1) to 2), we get :
1.5c + 4( 2200 - c ) = 5050
1.5c - 4c = 5050 - 8800
2.5c = 3750
c = 1500
a = 2200 - 1500
a = 700
Therefore, 1500 children and 700 adults attended the fair.

Answer:
x < -5
Step-by-step explanation:
The function is increasing where its slope is positive. That is where each point is higher than the one to its left. You see that is the case for all points to the left of the vertex, which is at x=-5.
The domain where the function is increasing is x < -5.
_____
Additional comment
At the vertex, the function is horizontal, neither increasing nor decreasing. So, the vertex itself is not included in the domains of increase or decrease.

which of the following is geometric sequence?
Answer:
Choice C
Step-by-step explanation:
A geometric sequence is usually one that multiply or divide to get to the next number in the sequence. So let's go through them to see which one gets multiplied since all of the choices are increasing.
Choice A:
[tex]1^{+3},4^{+1},5^{+4},9^{+5},14[/tex]
Nope that's not what we're looking for.
Choice B:
[tex]3^{+3},6^{+3},9^{+3},12^{+3},15[/tex]
This would be a perfect arithmetic sequence but not the type of sequence we are looking for.
Choice C:
[tex]6^{*3},18^{*3},54^{*3},162[/tex]
Yes! See how this one is multiplying by 3 and not adding or subtracting.
Choice D:
[tex]3^{+2},5^{+3},8^{+5},13^{+7},21[/tex]
Nope this is not it either.

Answer:
Step-by-step explanation:
the ratio between similar triangles are constant.
so 11/14 has to be equal to z/8 and also a15 = 11/14
so from this we can conclude that z = 8*14/11 = 10.18
Answer:
z = 11 and a = 12
Step-by-step explanation:
These two triangles are similar, in this case, the same angles but different sizes. The answer to this problem is the length of the sides of the triangles. You are given the right side's length on both triangles. The first triangle's sides are 3 (inches, cm, whatever form of measurement is being used) bigger than the second triangle's. Using this information, you can figure out the quantity of both a and z.
Hope this helps.

O Function
O Not a Function
O both
Answer:
Function
Step-by-step explanation:
These coordinates do represent a function. For a relation to be a function every y-value must have an x-value, this means x's cannot repeat. In this relation x's never repeat, they simply increase by one every time. Therefore, this is a function.

6x-1=-x+9
Answer:
x=10/7
Let's solve your equation step-by-step
6x−1=−x+9
Step 1: Add x to both sides
6x−1+x=−x+9+x
7x−1=9
Step 2: Add 1 to both sides
7x−1+1=9+1
7x=10
Step 3: Divide both sides by 7
7x/7=10/7
x=10/7
Answer:
x = 10 / 7
Step-by-step explanation:
6x - 1 = -x + 9
Add 1 to both sides of the equation.
6x - 1 = -x + 9
6x - 1 + 1 = -x + 9 + 1
Simplify
Add the numbers
6x - 1 + 1 = -x + 9 + 1
6x = -x + 9 + 1
Add the numbers
6x = -x + 9 + 1
6x = -x + 10
Add x to both sides of the equation.
6x = -x + 10
6x + x = -x + 10 + x
Simplify
Combine like terms
6x + x = -x + 10 + x
7x = -x + 10 + x
Combine like terms
7x = -x + 10 + x
7x = 10
Divide both sides of the equation by the same term
7x = 10
7x/7 = 10/7
Simplify
Cancel terms that are in both the numerator and denominator.
7x/7 = 10/7
x = 10/7
Solution
x = 10/7

Step-by-step explanation:
Given an expression that represents a submarine that began at a depth of 15 feet below sea level and ascended at a rate of feet per minute is as follows :
-320+15y
We need to find the depth of submarine after 15 minutes.
Put y = 15 in the above expression.
-320+15y = -320+15(15)
= -320 + 225
= -95
Hence, the submarine is below sea level at 95 feet.
