A glass aquarium with the dimensions shown has a mass of 5 kg when empty what is the mass of the aquarium when it is half full of water I will give you king thing if you answer good
Answers
The required mass of aquarium when it is half full of water is 10 kg.
Mass of the aquarium = 5kg
Length = 25 cm, width = 20 cm and height = 10 cm(when half filled)
Volume, is defined as the ratio of the mass of object to its density.
Since, density of the water = 1000 Kg/m³
Now Mass of the water = Volume x density
= 25/100 x 20/100 x 10/100 x 1000
= 0.005 x 1000
= 5 kg
Now, the total mass of the aquarium when half filed by water.
= mass of water + mass of aquarium
= 5 + 5
= 10 kg
Thus, the required mass of aquarium when it is half full of water is 10 kg.

Answers
The probability of picking a martian that has completed 4 years of high school or is a male is 72 / 85.
What is the probability?Probability determines the odds that a random event would happen. The odds of the event happening lie between 0 and 1.
The probability = (total number of people who have finished 4 years of high school / total number of martains) + (total number of males / total number of martains)
58 / 170 + 86/170 = 144 / 170 = 72 / 85

Solve for x in the following equation:
42x-5=23x+7
O x=-17
O x=-12
O x = 12
Ox=17
Answers
Answer:
x = 17
Step-by-step explanation:
1) Make the bases the same then rewrite.
4 = 2²
2^2(2x - 5) = 2^3x + 7
2) Since the bases are the same, set the exponents equal to each other.
2(2x -5) = 3x + 7
4x - 10 = 3x + 7
4x - 3x = 7 + 10
x = 17

I need help with number 15 and 16
Answers
Answer:
please see explanations
Step-by-step explanation:
For the first question,
Sum of angles in a triangle equal180°3x + 4x + 2x = 180
9x = 180°
Dividing bothsides by 9
9x/9 = 180/9
x = 20
The measure of the interior angles are :
3x = 3(20) = 60
4x = 4( 20) = 80
2x = 2(20) = 40
For the second question,
Let's find x first.
Angles on a straight line equal 180°.x + 92 = 180
x = 180 - 92 = 88°
To find A note that:
Exterior angle equal sum of opposite interior angles.A = 88° + 43°
A = 131°

A suspension bridge with weight uniformly distributed along its length has twin towers that extend 70 meters above the road surface and are 1200 meters apart. The cables are parabolic in shape and are suspended from the tops of the towers. The cables touch the road surface at the center of the bridge. Find the height of the cables at a point 300 meters from the center. (Assume that the road is level.)
Answers
Answer:
17.5 m
Step-by-step explanation:
The height of a parabola above its vertex is proportional to the square of the distance from the vertex.
Cable heightThe towers are 1200 m apart, so each is 600 m from center. The location of interest is 300 m from center, so 1/2 the distance to a tower. Since the height is proportional to the square of the distance, the height half-way to the tower will be (1/2)² = 1/4 the height of the tower.
(1/2)²×(70 m) = 17.5 m
The height of the cable 300 m from center will be 17.5 meters.

Use the Histogram below to answer

Considering the given histogram, we have that:
1. Chebyshev's Theorem.
2. At least 89%.
3. At least 75%.
What does Chebyshev’s Theorem state?When we have no information about the population distribution, Chebyshev's Theorem is used. It states that:
At least 75% of the measures are within 2 standard deviations of the mean.At least 89% of the measures are within 3 standard deviations of the mean.An in general terms, the percentage of measures within k standard deviations of the mean is given by [tex]100(1 - \frac{1}{k^{2}})[/tex].
We can see from the histogram that the distribution is not normal, hence Chebyshev's Theorem can be used.
-15 and 105 are within 3 standard deviations of the mean, hence the percentage is of at least 89%.
As stated in the bullet points, at least 75% of the measures are within 2 standard deviations of the mean.
