A right pyramid has a surface area of 258 cm2. A right cone has a base radius of 4 cm. The cone and pyramid have equal surface areas. What is the height of the cone to the nearest tenth of a centimetre?
Answers
The height of the cone to the nearest tenth of a centimeter is 17.40 cm.
From the given information provided in the question, we can solve this problem by following a few steps.
The surface area of a right pyramid is 258 cm² according to the question.
The surface area of the cone is equal to the surface area of the right pyramid. Therefore the surface area of the cone is also 258 cm².
The surface area of a cone is denoted as ( πrh + πr² ).
Where h is denoted as the height and, r is denoted as the radius of the cone which is 4 cm.
Hence the surface area of the cone is,
SA = (π× 4× h+ π× 4² ) cm²
Now, we can generate an equation, as both represent the value of the surface area of the cone.
(π× 4× h+ π× 4² ) = 258
Or, (12.56h + 39.44) = 258 [ The value of π is 3.14 ]
Or, 12.56h = 258 - 39.44 [ subtracting 39.44 from both sides ]
Or, 12.56h = 218.56
Or, h = 218.56/12.56 [ dividing both sides by 12.56]
Or, h = 17.40
Now, we can conclude that the height of the cone is 17.40 cm.

By using the fact that ∠4 and ∠5 add up to 180° and ∠5 = ∠7, we conclude that the measures of the angles are:
∠5 = ∠7 = 56°.
How to find the measures of the angles?For angles formed by the interception between lines meet the following property.
If the angles are one next to the other, the measures add up to 180°.
If not, then the two angles have the same measure.
This means that:
∠5 = ∠7
∠8 = ∠6
And so on.
If the two horizontal lines are parallel, then:
∠5 = ∠1
And we know that:
∠4 + ∠1 = 180°
124° + ∠1 = 180°
∠1 = 180° - 124° = 56°

2 = 2x4+b
b=-6
y = 2x - 6
Answer:
Slope intercept formula: y = 2x -6
Point Slope formula y = 2x-6
Step-by-step explanation:
1) Find the slope
2) Choose a point and plug it into the equation y = mx+b
3) Solve for b
4) Plug-in new slope (m) and new y-intercept (b) into equation y = mx+b
Solving:
4 = x1
2 = y1
7 = x2
8 = y2
to find slope with slope formula:
m = y2-y1/x2-x1 = 8-2/7-4 = 6/3 = 2
now plug in,
y = 2x+b
to find b, take any one of the pair
(i will choose (4,2) )
2 = 2(4) + b
now solve for b,
2 = 8+b
b = -6
Slope intercept formula: y = 2x -6
for point slope: y-y1 = m(x-x1)
as we know our slope is 2 and points are (0,-6) where 0 is x1 and -6 is y1
now we plug in,
y-(-6) = 2(x-0)
y+6 = 2x
Point Slope formula y = 2x-6

The dimensions of the rectangle will be equal to 10 by 4.
A rectangle may be defined as the closed figure having four sides with the interior angles equal to 90°. it has two dimensions the length and the width. The area of a rectangle may be defined as the product of its length and width. According to the question the area of the rectangle is given as 40 square units. Let us assume the length as 'l' units and width as 'b' units. It is given that length is 6 units greater than the width that is l = (b + 6).
Now, the area of the rectangle = l×b
40 = (b + 6)×b
40 = b² + 6b
=> b² + 6b - 40 = 0
=> b = [-6 ± √(36 + 160)]/2
=> b = (-6 ± 14)/2
=>b = 4 units, since width cannot be negative.
Now, length = b + 6 = 10 units.

Answer:
Second Choice: 8.73b + 171.48 > 381
Step-by-step explanation:
This is a tricky question because the first two choices both represent an inequality that satisfy the conditions
First, let's eliminate obvious wrong choices.
If b represents the number of bags of dog food and one bag costs $8.73, there should be term 8.73b somewhere in the inequality since 8.73b represents the total $ cost of b bags of dog food.
This means we can eliminate the last two choices
Let's deal with the knowns and compute the dollar amounts of each of the products being donated
30 cans of cat food at $0.57 per can = 0.57 x 30 = $17.10
34 cans of dog food at $0.84 per can = 0.84 x 34 = $28.56
18 bags of cat food at $$6.99 per bag = 6.99 x 18 = $125.82
The sum of these is $171.48
She is also donating b bags of dog food at $8.73 per bag = 8.73 x b = $8.73b
So the total cost of the donation =
8,73b + 171.48 which has to exceed 381
So the inequality is
8.73b + 171.48 > 381
Which is the choice you have selected and I believe it is correct
Now, the tricky part comes because if you subtract 171.84 from both sides of the inequality we get
8.73b > 318 - 171.48
Both inequalities are equivalent but we would not write an inequality of the type where the RHS is a mathematical expression. We would instead simplify the right hand side and write it as
8.73b > 209.52 (381-171.48 = 209.52)
I believe the way the question is worded is the LHS should be the $sum of all the donations and the RHS the minimum value.
So the best choice is choice 2: 8.73b + 171.48 > 381
i hope that helps.

Answers
The probability that the shorts of the basketball team will be of a different color than the jersey is 2/3.
Probability can be found using the following formula;
probability = number of favorable outcomes or events ÷ total number of outcomes or events
In order to calculate the probability that the shorts will be of a different color than the jersey, we first determine the total number of combinations that are possible;
1- Black-Black
2- Black-White
3- Black-Gold
4- Gold-Black
5- Gold-White
6- Gold-Gold
Hence there are a total of 6 possible combinations of shorts and jerseys out of which 2 are the same and 4 are different.
Therefore the probability that the shorts will be of a different color can be calculated as follows;
probability = number of favorable outcomes or events ÷ total number of outcomes or events
probability = 4 ÷ 6
probability = 2/3
Hence, 2/3 is the probability that the shorts will be of a different color than the jersey.

The mathematical symbol for arcsin, commonly known as inverse sine, is arcsin x or sin-1x (read as sine inverse x). Sin-1x is not the same as (sin x)-1; that is, sin-1x is not the reciprocal function of sin x. This is an important distinction to make. We may use the six inverse trigonometric functions arccos, arcsin, arctan, arcsec, arccsc, and arccot to calculate angles.
