30 cm
Work out the total surface area of this cuboid.
(4)
Length = 80
Breadth = 30
Height = 30
Total surface area of a cuboid is=
2 ( lb + bh + hl )
Putting the values in the formula,
We get,
= 2 [ (80 x 30) + (30 x 30) + (30 x 80)]
= 2 (2400 + 900 + 2400)
= 8100 cm²

Answer:
10.25%
Step-by-step explanation:
Let the original number be represented with x.
Increase by 5% = 5% of x = 5/100 x X = 0.05x
So, the next number = x + 0.05x = 1.05x
Increase again by 5% = 5% of 1.05x = 5/100
x1.05x = 0.05 x 1.05x = 0.0525
So, the current number = 1.05x + 0.0525x =1.1025x
[tex] \frac{1.1025x - x}{x} = 0.1025 \times 100 = 10.25\%[/tex]

Among all pairs of numbers whose difference is 6, find a pair whose product is as small as possible. What is the minimum produc The pair of numbers whose difference is 6 and whose product is as small as possible is ?
Answer:
pairs of numbers is 3,-3
Step-by-step explanation:
The computation is shown below:
Let us assume a and b are the pairs of the numbers whose difference is 6
i.e.
a - b = 6
a = 6 + b
So
f = ab
f = (6 + b)b is minimum
Now
d ÷ db (6+ b)b = 0
(6+ b) + b = 0
2b = -6
b = -3
Now
a = 6 + b
= 3
So pairs of numbers is 3,-3

AD = 2(5/2) = 5
AD is a diameter.
any triangle in a circle with the hypotenuse as the diameter is a right triangle.
Draw a line from point A to point C.
ΔACD is a right triangle.
Solve for ∠CAD:
sin CAD = 3/5 = 0.6000
∠CAD = 36.87°
arc CD = 2 x 36.87° = 73.74°
arc BC = arc CD = 73.74°
arc DB = 147.48°
∠BAD = 1/2 (147.48°) = 73.74°
draw a line from point D to point B
ΔBAD is a right triangle.
cos 73.74° = AB/5
AB = 1.4

The rectangular box can be constructed from the pattern above. The box has a length of 8 units, a width of 2 units, and a height of 2 units. What is the surface area of the box?
Answer:
72 units
Step-by-step explanation:
SA=2lw+2lh+2hw
SA=2(8x2) + 2(8x2) + 2(2x2) Note, Not distributive
SA= 2(16) + 2(16) + 2(4)
SA= 32 + 32 + 8
SA= 72
Answer:
72 sq. units
Step-by-step explanation:
There are four rectangles of length 8 units and width 2 units, and two squares of length 2 units each.
area of one rectangle=8×2=16 sq. units
area of four rectangles=16×4=64 sq. units
area of on square=2×2=4 sq. units
area of two squares=4×2=8 sq. units
total surface area=64+8=72 sq. units
Tell whether the ordered pair (-1,3) is a solution of the system of linear equations. y=-7x-4 and y=8x+5
Answer:
Since it does not plug in to the second linear equation, the ordered pair is not a solution of the linear system.
Step-by-step explanation:
(-1,3); y = -7x -4 y = 8x + 5 3 =7 - 4 3 =/ - 8 + 5
For a system of equations to have no real solution, the lines of the equations must be parallel to each other. The ordered pair (-1,3) is not the solution of the given system of equations.
What is the System of equations?Inconsistent SystemFor a system of equations to have no real solution, the lines of the equations must be parallel to each other.
Consistent System
1. Dependent Consistent System
For a system of the equation to be a Dependent Consistent System, the system must have multiple solutions for which the lines of the equation must be coinciding.
2. Independent Consistent System
For a system of the equation to be an Independent Consistent System the system must have one unique solution for which the lines of the equation must intersect at a particular.
The solution of the equation can be found by plotting the equation on the graph. Therefore, the point at which the equation will intersect will the solution of the system of equation.
Since the solution of the system of equation is (-0.6, 0.2), there exists only one single solution for the system of equation. therefore, the (-1,3) is not the solution of the system of equation.
Hence, the ordered pair (-1,3) is not the solution of the given system of equations.

180:300 can be simplified by dividing both by 6 (GCF)
Answer: 1) 180:120 2) 180:300
Step-by-step explanation: so girls to boys there is 180 girls so to find the boys you do 300-180 because there’s only males and females in the school so if they give you the number of females the rest are males. And because they gave you the girls and the total students it’s just 180:300

g Suppose a kind of disease exists within 1% of the population and a certain test can help diagnose it. If someone has the disease, the test will give a positive result with a 95% probability. On the other hand, if someone does not have the disease, the test result will give a negative result 97% of the time. If David did the test once, what is the probability that the test result is positive
Answer:
0.0392 = 3.92% probability that the test result is positive.
Step-by-step explanation:
Probability of a positive test:
95% of 1%(person has the disease)
100 - 97 = 3% of 100 - 1 = 99%(person does not have the disease).
What is the probability that the test result is positive?
[tex]p = 0.95*0.01 + 0.03*0.99 = 0.0392[/tex]
0.0392 = 3.92% probability that the test result is positive.
Which numbers belong to the solution set of the inequality? x+6= 42
Answer:
36
Step-by-step explanation:
Answer:
x=36 is your answer
Step-by-step explanation:
Simplifying
x + 6 = 42
Reorder the terms:
6 + x = 42
Solving
6 + x = 42
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + x = 42 + -6
Combine like terms: 6 + -6 = 0
0 + x = 42 + -6
x = 42 + -6
Combine like terms: 42 + -6 = 36
x = 36
Simplifying
x = 36
