Round the divisor to the nearest 10 or 100, depending on how many digits are in the divisor.
Round the dividend to the nearest 10, 100, or 1,000 so that all of the digits, except the first one are zeros.
Divide 600 by 30.

A tree cast a 16 foot long shadow on level ground a forestry student uses a clinometer to determine the sun is that a 70° angle of elevation what is the height of the tree to the nearest whole foot
Answer:
15foot
Step-by-step explanation:
The set up will give a right angled triangle.
The length of the shadow will be the hypotenuse = 16foot
The height of the tree will be the opposite = x
The angle of elevation = 70°
Using the SOH CAH TOA trig identity
Sin theta = opposite/hypotenuse
Sin 70 = x/16
x=16sin70
x = 15.04feet
Hence the height of the tree to the nearest whole foot is 15foot

Answer:
4·log(16) = 16·log(2) ≈ 4.81648
Step-by-step explanation:
The rules of logarithms are ...
log(a^b) = b·log(a)
Here, we have ...
log(16^4) = 4·log(16)
However, we recognize that 16 = 2^4, so this becomes ...
log(16^4) = 4·(log(2^4)) = 4·4·log(2) = 16·log(2)
The base-10 logarithm of 2 is about 0.30103, so this is ...
log(16^4) ≈ 16·0.30103 = 4.81648
Choose the form of the answer you need:
log(16^4) = 4·log(16) = 16·log(2) ≈ 4.81648

Move words to the blanks and equations to the boxes to prove that vertical angles <21 and <23 are congruent.
Answer:
See proof below
Step-by-step explanation:
From the given diagram, we can see that <2 and <3 lies on the same straight line, hence the sum of the angles is 180 degrees (supplementary)
<2 + <3 = 180 .... 1
Similarly. <1 and <2 are also supplementary angles
<1 + <2 = 180 .... 2
Subtract 1 from 2;
<3 - < 1 + <2 - <2 = 180 - 180
<3 - <1 +0 = 0
<3 - <1 = 0
Add <1 to both sides
<3 - <1 + <1 = 0+<1
<3 = <1 (Proved!)
This shows that <3 and <1 are equal
We can also conclude that <3 and <1 are vertically opposite angles and vertically opposite angles are equal

Ella traveled at an average speed of 65 per hour for 2.5 hours and then traveled at an average speed of 60 miles per hour for 3.5 hours. What was the total distance in miles traveled by Ella? *
Answer:
372.5 miles
Step-by-step explanation:
First, find how many miles she traveled at 65 mph:
65(2.5)
= 162.5
Then, find how many she traveled at 60 mph:
60(3.5)
= 210
Add these together:
162.5 + 210
= 372.5
So, Ella traveled 372.5 miles in total
The sixth-graders at Barbara's school got to choose between a field trip to a museum and a field trip to a factory. 39 sixth-graders picked the museum and 26 sixth-graders picked the factory. What percentage of the sixth-graders picked the museum
Answer: 60%
Step-by-step explanation:
Sixth-graders that picked the museum = 39
Sixth-graders that picked the factory = 26
Total number of sixth graders = 39 + 26 = 65
Therefore, the percentage of the sixth-graders that picked the museum would be:
= Sixth-graders that picked the museum / Total number of sixth graders × 100
= 39/65 × 100
= 60%
A rock is thrown straight up from the top of a bridge that is 75 ft high with an initial velocity of 32 ft/s. The height of the object can be modeled by the equation s(t) = -16t^2 + 32t + 75. Determine the time(s) the ball is lower than the bridge in interval notation.
In two or more complete sentences, explain why (-∞, 0) is not included in the solution.
I tried to solve it, but given that the Critical Numbers/Roots are 0 and 2, the solution should be (-∞, 0) ∪ (2, ∞)
Step-by-step explanation:
When -16t² + 32t + 75 < 75, -16t² + 32t < 0.
=> 16t(2 - t) < 0, t < 0 or t > 2.
However t < 0 is rejected as time cannot be a negative value. Hence the solution in interval notation is (2, ∞).

Evaluate the function for h(1)
h(x) = |1 – 7x|
Answer:
We conclude that:
[tex]h\left(1\right)=6[/tex]
Step-by-step explanation:
Given
The function is
[tex]h\left(x\right)\:=\:|1\:-\:7x|[/tex]
To determine
h(1) = ?
Given the function
[tex]h\left(x\right)\:=\:|1\:-\:7x|[/tex]
substitute x = 1 in the function
[tex]h\left(1\right)=\left|1-7\left(1\right)\right|[/tex]
[tex]h(1)=\left|1-7\right|[/tex]
[tex]h(1)=\left|-6\right|[/tex]
Apply absolute rule: |-a| = a
[tex]h\left(1\right)=6[/tex]
Therefore, we conclude that:
[tex]h\left(1\right)=6[/tex]

What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the length of the sides of the triangle are 15 cm , 7 cm and 5 cm respectively
And , there are no triangles that can be formed with these measurements
This is because the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, 15 > 7 + 5, which means that a triangle cannot be formed using these three sides. Therefore, the answer is none.
Hence , the triangle is solved

given the figure below, calculate the area
Answer:
1+√3
Step-by-step explanation:
Area of the triangle = 1/2 * base * height
Area of the triangle = 1/2 * AC * BD
We need to get AC
AC = AD+DC
Get base AD using SOH CAH TOA
tan 45 = 4/AD
AD = 4/tan45
AD = 4/1
AD = 4
Get DC
tan 30 = 4/DC
DC = 4/tan 30
DC = 4/(1/√3)
DC = 4√3
AC = 4 + 4√3
AC = 4(1+√3)
Get the Area of the triangle
Area = 1/2 * 4 * 4(1+√3)
Area of the triangle = 1+√3

3.2b + 10 = -1.7b - 4.7
Answer:
b = -3
Step-by-step explanation:
3.2b + 10 = -1.7b - 4.7
add 1.7b to each side
3.2b+1.7b + 10 = -1.7b+1.7b - 4.7
4.9b +10 = -4.7
Subtract 10 from each side
4.9b +10-10 = -4.7-10
4.9b = -14.7
Divide each side by 4.9
4.9/4.9 = -14.7/4.9
b = -3
1) You learn 15 vocabulary words a week & ahve already learned 75. Type an equation for the total vocabulary words you will learn in x week.
2) Find the slope
3) How many new vocabulary words do you learn in 13 weeks?
4) How many weeks will it take you to learn 390 vocabulary words?
Answer:
1) Words learned=15x+75
2) 15 is the slope
3) 270 words
4) 21 weeks
Step-by-step explanation:
Let x be equal to the number of weeks that pass.
Let y be equal to the number of words we learn.
1) We're told that we learn 15 words per week. Therefore, 15x would equal the number of words we learn. However, because we already know 75, we add that to 15x, giving us this equation:
y=15x+75
2) The slope is the same thing as the rate of change in a situation. In this scenario, every week, we learn 15 words. Therefore, the rate of change, or the slope, is 15.
3) To find this, plug 13 into our equation as x and solve for y.
y=15x+75
y=15(13)+75
y=195+75
y=270
Therefore, we would learn 270 vocabulary words in total in 13 weeks.
4) To find this, plug 390 into our equation as y and solve for x.
y=15x+75
390=15x+75
Subtract 75 on both sides to isolate x
390-75=15x+75-75
315=15x
Divide both sides by 15
315/15=15x/15
21=x
Therefore, it would take 21 weeks to learn 390 new vocabulary words.
