A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound?
Answer:
1583362.7 termites
Step-by-step explanation:
A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound
The formula for the volume of a cone
= πr²h/3
Radius = r = 60cm
Height = h = 1.4 m
Converting to centimeters.=
1m = 100cm
1.4m = x
x = 1.4 × 100cm = 140 cm
Volume of the cone = π × 60² × 140/3
527787.5658 cm³
From the above question
1cm³ = 3 termites
527787.5658 cm³ = x
Cross Multiply
x = 3 × 527787.5658
x = 1583362.6974 termites
Approximately.= 1583362.7 termites

Can someone please answer this please for god's sake
Answer:
x = 36 degrees
y = 48 degrees
Step-by-step explanation:
The two given triangles are congruent
Hence, we can say that the interior angles are equal
We shall use the angle markings on each of the triangles
Using the markings, we can see that y is 48 degrees
Now, let us find the last angle measure of the first triangle
Mathematically, the sum of angles in a triangle is 180
Thus;
108 + 48 + A = 180
A = 180 - 48 - 108
A = 180 - 156 = 24
Now, the measure 2x-y is equal to this;
Hence;
2x -y = 24
2x = 24 + y
we have that y = 48
2x = 24 + 48
2x = 72
x = 72/2
x = 36 degrees

C is always the longest side of the triangle. In your question, it would be the side without any measurement.
It doesn't matter which side is A and which side is B, so, suppose that A is 12 and B is 5.
Now just solve for C
C=[tex]\sqrt{12^{2} + 5^{2} }[/tex]
C=[tex]\sqrt{144+25}[/tex]
C=13
Therefore, the missing side is 13 cm

What is Percentage?The percentage formula is used to calculate the amount or percentage of anything in terms of 100. Percentage indicates "per hundred" in its most basic form. The percentage formula is used to express a number between zero and one. It is a number that is expressed as a fraction of 100. It is represented by the sign% and is mostly used to compare and find ratios.
Given:
The percent for Video Game= 25%
and, percent for Research = 5%
So, 25% of 30 = 25 / 100 x 30 = 7.5
5% of 30 = 5/100 x 30 = 1.5
So, the the number of hour spend on more on Video game
= 7.5 - 1.5
= 6 hour

Josh used one hundred dollars less than three-fourths of his paycheck to buy a new N. it the cost of

Please don’t put the answer in a link.
Answer:$175
Step-by-step explanation:
The amount of his paycheck would be $ 784.
What is the solution for an equation?The solution of an equation refers usually to the values of the variables involved in that equation which if substituted in place of those variable would give a true mathematical statement.
WE have been given that Josh used one hundred dollars less than three-fourths of his paycheck to buy a new N the cost of the new TV was $488.
Let P = pay amount
3/4 P -100 = 488
Now add 100 to both sides of the equation
3/4 P = 588
Then multiply both sides of the equation by 4/3;
P = $ 784
The amount of his paycheck would be $ 784.

For which equation is g = 0 not the solution?
12 g = 0
3 g = 30
g + 8 = 8
9 g = 0
Answer:
3g = 30
Step-by-step explanation:
Well, lets check each one to see if any leaves g = 0
12g = 0 (Given)
÷12 ÷12 (Get "g" on its own)
g = 0 (0 ÷ 12 = 0)
We know it is not this one since g = 0
3g = 30 (Given)
÷3 ÷3 (Get "g" on its own)
g = 10 (30 ÷ 3 = 10)
This is our answer since g = 10 in this equation, and not g = 0 we know that this is our equation.
Just in case, I will do the other options just not as in-depth!
g + 8 = 8
-8 -8
g = 0
9g = 0
÷9 ÷9
g = 0

winning. The probability that you lose the next two matches is
(a) 0.16
(b) 0.40
(c) 0.64
(d) 0.36
The probability that you lose the next two matches is 0.4. The correct option is B.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of samples
Given that you play tennis regularly with a friend, and from past experience, you believe that the outcome of each match is independent. For any given match you have a probability of 0.6 of winning.
The probability that you lose the next two matches is calculated as:-
Probability = 1 - 0.6
Probability = 0.4
Therefore, the probability that you lose the next two matches is 0.4. The correct option is B.
