Answer:
B 17.5 ft
Step-by-step explanation:
tangent = opposite / adjacent
tan 35° = h / 25
multiply both sides by 25
h = 25 (tan 35°)
tan 35° = 0.70 (from your calculator)
h = 25 (0.70)
h = 17.51 ft.
If we have a conversion factor given to us in a fraction form that cannot be represented as an easy decimal, what can we do?
a. Conclude that the units cannot be converted to one another.
b. Assume the conversion factor is 1.
c. Attempt to use a conversion factor for different units of measurement.
d. Leave the conversion factor in fraction form.
Answer:
D) Leave the conversion factor in fraction form
Step-by-step explanation:
Leave the conversion factor in fraction form, when fraction form that cannot be represented as an easy decimal. The correct option is option D.
What is conversion Factor?A conversion factor is a ratio expressed as a fraction that equals 1. When we use conversion factors to convert units, we multiply our original measurement by the conversion factor to get the same measurements expressed in new units.
If we have a conversion factor given to us in a fraction form that cannot be represented as an easy decimal. Leave the conversion factor in fraction form.
Because there are two type of decimals:
Terminating decimal expansion means the decimal expansion of a number which stops after a certain number of decimal places. For example, if we divide 100 by 16, the answer comes out as 6.25.Since the number of decimal place in 6.25 is 2,i.e., it stops after a certain number of decimal places, it is called a terminating decimal expansion.
On the other hand, if the decimal expansion of a number does not stop at all, then it is called a non-terminating decimal expansion. For example, if we divide 100 by 7, then the answer comes out to be 14.28571428571…….. . The decimal expansion does not stop. This is known as a non-terminating decimal expansion.
In general, if a fraction has a denominator of the form 2^n*5^m, where m and n are non-negative integers, then it will have a terminating decimal expansion. For example, 100/16 has denominator 16 which is of the form 2^4*5^0, so it has a terminating decimal expansion.
If a fraction has a denominator which is not of the form 2^n*5^m, where m and n are non-negative integers, then it will have a non-terminating decimal expansion. For example, 100/7 has a denominator 7 which is not of the form 2^n*5^m so it has a non-terminating decimal expansion.
Hence, Leave the conversion factor in fraction form, when fraction form that cannot be represented as an easy decimal.

the lengths of the sides of a triangle are 2n, n^2 and n+5 for what value of n do these lengths not make a triangle ?
Answer:
Step-by-step explanation:
Try n = 2
2n = 4
n^2 = 4
n+5 = 7 That works. It will make a triangle since the 2 smallest numbers are bigger than 7
Try n = 3
2n = 6
n^2 = 9
n + 5 = 8 That works. Same reason as above.
n = 4
2n = 8
n^2 = 16
n + 5 = 9 That works. Same reason.
n = 5
2n = 10
n^2 = 25
n+5 = 10 Aha! That doesn't work. the two smaller numbers only = 20.
There are likely many numbers that don't work. I'll try one more
n = 6
2n = 12
n + 5 = 11
n^2 = 36 This won't work either. Same reason as n = 5.

if x,y are in inverse proportion then complete the following table x= 42 y=-15 , x=30 y=-----
Answer:
when x=30, y = -21
Step-by-step explanation:
x = k/y
x = 42 y = -15
x = k/y
42 = k/-15
Cross product
42 * -15 = k
-630 = k
k = - 630
Find y when x=30
x = k/y
30 = -630/y
Cross product
30 * y = - 630
30y = - 630
y = - 630/30
y = -21
when x=30, y = -21
Al and Tom are painting a shed. Working alone, Al can paint the shed in 2 hrs. Together they can paint the shed in 1.5 hours. How long would it take Tom to paint the shed on his own?
Answer:
6 hours.
Step-by-step explanation:
The formula sort of has to be invented.
Al
rate = 1 shed / 2 hours
Tom
rate = 1 shed / x hours.
Together.
rate = 1 shed / 1.5 hours.
Equation
1 shed / 2 hours + 1 shed / x hours = 1 shed / 1.5 hours.
1/2 + 1/x = 1/1.5 Put the fractions over a common denominator.
(x + 2) / 2x = 1 / 1.5 Cross Multiply
1.5(x + 2) = 2x Remove the Brackets.
1.5x + 3 = 2x Subtract 1.5x from both sides
3 = 2x - 1.5x
3 = 0.5x Multiply both sides by 2
6 = x
It would take Al 6 hours to do the shed on his own.
✨✨Answer number 7please ✨✨
Answer: A
Step-by-step explanation: This is a rotation. An easy way to tell the difference between a rotation and a reflection is that the order of the points will not change in a rotation. For this problem, pre-image ABCD is still in the order of ABCD when mapped to the image. (You can still follow along the points in that order). When something is reflected, the points swap orders and you would not be able to follow the points in order.
Now that we know this is a rotation, Notice A’ B’ C’ and D’ are all left of the pre-image. This means the mapped image moves counter clockwise.

c=√14^2 +3^2
c=√=196+9
c=14.31782106327
c=14.3 yds.
Answer:
XZ = 14.32 yd
Step-by-step explanation:
Use the Pythagorean theorem
14^2 + 3^2 = XZ^2
196 + 9 = XZ^2
XZ^2 = 205
XZ = 14.32 yd
Circle A has center of (6, 7), and a radius of 4 and circle B has a center of (2, 4), and a radius of 16.
Answer:
See solutions below
Explanation
We are to find the equation of circle A and B
The equation of a circle is expressed as;
(x-a)^2 + (y-b)^2 = r^2
(a, b) is the centre and r is the radius
For Circle A that has center of (6, 7), and a radius of 4
Substitute;
(x-6)^2 + (y-7)^2 = 4^2
(x-6)^2+(y-7)^2 = 16
Hence the equation of circle A is (x-6)^2+(y-7)^2 = 16
For circle B:
If circle B has a center of (2, 4), and a radius of 16
The equation is expressed as;
(x-2)^2+(x-4)^2 = 16^2
(x-2)^2+(x-4)^2 = 256
Hence the required equation is (x-2)^2+(x-4)^2 = 256

MUST HAVE ANSWERED MY PREVIOUS QUESTION!!!
Compare the theoretical probabilities to your experimental probabilities. Why might there be a difference?
Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.
-
Answer:
Theoretical probability is what is expected to happen, where as experimental probability is what happens when you test out that theory. There is a very unlikely chance that a concept in theory would be the same as a concept in action, therefore explaining why these answers are not alike.

How to solve inequality equations?
An inequality is a mathematical expression using the symbols >, <, ≥, and ≤. Many straightforward inequalities can be resolved by adding, taking away, multiplying, or dividing both sides until the variable is all that remains. On multiplying or dividing both sides with negative number changes the direction of inequality. If we flip the number, we just have to flip the inequality symbol also.
Inequality:
2x-3> 2x-5/2
2x - 2x > -5/2 + 3
2x - 2x > -2.5 + 3
0 > -2.5 + 3
0 > 0.5
This shows that solution set will not contain any elements, i.e. x ∈ ∅
Therefore, Solution set = ∅
