In 1999 Daniel was 146 cm tall. He grew to be 176 cm by the year 2006. What was Daniel's rate of growth over this period of his life? (Find growth each year)
Answer:
he grows by 5 cm every year between 1999 and 2006
Step-by-step explanation:
This is a arithmetic progression problem with the formula;
T_n = a + (n - 1)d
We are told that In 1999 Daniel was 146 cm tall. He grew to be 176 cm by the year 2006.
Thus;
a = 146
d = 2006 - 1999 = 7
Thus;
176 = 146 + (7 - 1)d
176 - 146 = 6d
30 = 6d
d = 30/6
d = 5 cm
Thus, he grows by 5 cm every year between 1999 and 2006
what is the square root of 83, 10, 63, and 99?
Answer: square root of 10 - 100 3.162
√63 =√32⋅7=√32⋅√7=3√7.
Thus, the square root of 99 lies somewhere between 9.9 and 10. Choosing an estimate in the middle of this range, we know that sqrt(99) is approximately equal to 9.95, with an error of not more than 0.05.
Step-by-step explanation:
Explanation: √83 is an irrational number. You won't be able to simplify it any further either, since it doesn't have any perfect square factors.
square root of 10 - 100 3.162

Given ABC with incenter D, find mACD if mACB = 3x + 54 and m ACD = x + 31.
Given:
In triangle ABC, D is incenter m∠ACB = 3x + 54 and m∠ACD = x + 31.
To find:
m∠ACD.
Solution:
We know that,
Incenter of a triangle is the intersection point of all angle bisectors.
[tex]\angle ACD=\angle BCD[/tex] ...(i)
Now,
[tex]\angle ACB=\angle ACD+\angle BCD[/tex]
[tex]\angle ACB=\angle ACD+\angle ACD[/tex] [Using (i)]
[tex]\angle ACB=2\angle ACD[/tex]
Substitute the values, we get
[tex]3x+54=2(x+31)[/tex]
[tex]3x+54=2x+62[/tex]
[tex]3x-2x=62-54[/tex]
[tex]x=8[/tex]
The value of x is 8.
[tex]m\angle ACD=x+31[/tex]
[tex]m\angle ACD=8+31[/tex]
[tex]m\angle ACD=39[/tex]
Therefore, the measure of angle ACD is 39 degrees.

A tree initially measured 2712
feet tall. Over the next 312
years, it grew to a final height of 3512
feet. During those 312
years, what was the average yearly growth rate of the height of the tree?
Answer:
2.56 feet / year to the nearest hundredth.
Step-by-step explanation:
Average rate = difference in height / number of years
= (3512-2712) / 312
= 800/312
= 2.56 feet / year

In a standard Normal distribution, what percentage of observations lie between z = 0.37 and z = 1.65?
Find the z-table here.
30.62%
40.52%
59.48%
69.38%
Answer:
c
Step-by-step explanation:
The solution is, The percent is 4.9471%
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
given that,
Here, we want to find the percentage of observations that lie above
z = 1.65
Firstly we find the probability of x < z = 1.65
Hence P ( x > 1.65)
This is obtainable from the standard normal distribution table
The value of P(x > 1.65) = 0.049471
This represents a percentage of 4.9471%
Hence, The solution is, The percent is 4.9471%

Given quadrilateral ABCD shown, answer the following:
(a) Determine the slope of all four sides either algebraically or graphically. Label all slopes.
(b) State all pairs of parallel sides based on (a).
(c) What type of figure does this represent?
Answer:
See below
Step-by-step explanation:
a) Slope of the lines
Slope = rise / run
AB = 2/10 = 1/5DC = 2/10 = 1/5AD = 8/2 = 4BC = 8/2 = 4b) Parallel line have a same slope
AD and BC are parallel AB and DC are parallelc) Since two pairs of parallel sides, the figure is a parallelogram

A pair of numbers has a GCF of 6 and a LCM of 60. What could the numbers be? Explain.
6 and 60 could be the pair of numbers
How to determine the numbers?The given parameters are:
GCF = 6
LCM = 60
Let the two numbers be x and y
So, we have
x * y = GCF * LCM
This gives
x * y = 6 * 60
By comparison, we have
x = 6 and y = 60
Hence, 6 and 60 could be the pair of numbers

What is Trigonometry?
Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
Using
sin (A + B) = sin A cos B + cos A sin B
So,
sin(120 + 45)
= sin 120 * cos 45 + sin 45 * cos 120
= sin ( 90+ 30)* 1/√2 + 1/√2* cos ( 90 +30)
= cos 30* 1/√2- 1/√2* sin 30
=√3/2* 1/√2 - 1/√2 *01/2
= (√3-1) / 2√2
