Elizabeth changed her time for the mile walk from 30 minutes to 24 minutes. What was the percent of change?
Answers
Basically, we are trying to find the change from 30 to 24 in terms of percent. We do this in three steps:
1) Find the difference between 30 and 24 as a number.
2) Divide the result from Step 1 by the starting number 30.
3) Multiply the result from Step 2 by 100 to get it in terms of percent.
The three steps above can be made into a formula. Thus, to find the percent change from 30 to 24, we use this formula:
((Y-X)/X)*100 = Percent Change
X is the starting number 30, and Y is the ending number 24 that it changed to. When we enter these numbers into the formula, we get:
((24-30)/30)*100 = -20.00%
Thus, the answer to the question "What is the Percent Change from 30 to 24?" is:
-20.00%

The side lengths of a triangle are 5,√3,√28. Is the triangle a right triangle? How would I solve this?
Answers
Answer:
it is a right triangle.
Step-by-step explanation:
you would solve by using pythagorean theorem. Firstly you would find the square roots. Then write the pythagorean theorem out replacing the variables with the corresponding numbers. All you do for this is find the greatest number and that is c. Lastly you would add the square roots of a and b, if this equals 28 then they are equal. Ask more questions if I did not explain this clearly.

Step-by-step explanation:
Answer:
Multiply both the numerator and the denominator by the same whole number.
For example;
If you multiply 1/2 by 2/2, this will equal 2/4. You can simplify 2/4 to 1/2.
So to find 1/2 to be equivalent to another fraction, multiply both the numerator and the denominator by the same number to find a fraction that equals 1/2.

eBook
Answers
Answer:
Height of the tree is 40.0 meters.
Step-by-step explanation:
From ΔABC,
m∠ABC = 90°
Since, m∠ABC = m∠CBD + m∠ABD
90° = 6° + m∠ABD
m∠ABD = 90°- 6° = 84°
By triangle sum theorem in ΔABD,
m∠ABD + m∠BDA + m∠DAB = 180°
84° + 29° + m∠BDA = 180°
m∠BDA = 180° - 113°
= 67°
By sine rule in ΔABD,
[tex]\frac{\text{sin}(\angle BDA)}{d}= \frac{\text{sin}(\angle ABD)}{h}[/tex]
[tex]\frac{\text{sin}(67)}{37}= \frac{\text{sin}(84)}{h}[/tex]
h = [tex]\frac{\text{sin}(84)\times 37}{\text{sin}(67)}[/tex]
h = 39.98
h ≈ 40.0 meters
Therefore, height of the tree is 40.0 meters.
The sine rule is the ratio of the side length to the sine of the opposite angles. Then the height of the tree is 40 meters.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a triangle.
Because of prevailing winds, a tree grew so that it was leaning 6º from the vertical.
At a point d = 37 meters from the tree, the angle of elevation to the top of the trees is a = 29° (see figure).
∠ABC = 90
We have
In ΔABC
∠ABC = ∠CBD + ∠ABD
∠ABD = 90 - 6
∠ABD = 84
By triangle sum in ΔABD, we have
∠ABD + ∠BDA + ∠DAB = 180
∠BDA = 180 - 84 - 29
∠BDA = 67
Then by the sine rule, we have
[tex]\begin{aligned} \dfrac{\sin \angle BDA}{d} &= \dfrac{ \sin \angle ABD }{h}\\\\\dfrac{\sin 67}{37} &= \dfrac{\sin 84}{h}\\\\h &= \dfrac{\sin 84} \times 37{\sin 67}\\\\h &= 39.98 \approx 40 \end{aligned}[/tex]

Answers
Answer:

Step-by-step explanation:
We need to find the value of 2021-2223+2425.
Firstly subtract 2223 from 2021.
2021-2223 = -202
Now add -202 and 2425. So,
2425 +(-202) = 2223
So, the value of 2021-2223+2425 is 2223. Hence, this is the required solution.
