Answer:
7.04× 10^5
Step-by-step explanation:
6.72 x 10^5= 6.72 x 10^(4+1)= 6.72 x 10^1 ×10^4
= 67.2 x 10^4
(67.2 x 10^4)+ (3.2 x 10^4)
(67.2+3.2) × 10^4 = 70.4 × 10^4
7.04× 10^5
Answer:
7.04× 10^5 Step-by-step explanation:
A 17-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground feet from the base of the building. How high up the wall does the ladder reach?
Answer:
15 feet..
taking base as 8m
Given: ladder = 17 m and base = 8 m
The ladder forms a right triangle with the base of 8 m, the wall will be 15 m and the ladder (hypotenuse) is 17 m.
Let’s say you did not know that this was a standard 8–15–17 right triangle.
This is how you can figure it out:
hypotenuse(h)22 = side2112 + side2222
Let side11 = base and side22 = wall
1722 = 822 + wall22
wall = 172−82−−−−−−−√172−82
wall = 289−64−−−−−−−√289−64
wall = 225−−−√225
wall = 15 feet
Height of wall is 15 feet
Given:
Length of ladder = 17 feet
Base distance from ladder = 8 feet (Missing information)
Find:
Height of wall
Computation:
Length of ladder = hypotenuse
Base distance from ladder = Base
Height of wall = Perpendicular
Using Pythagorean theorem
[tex]Perpendicular = \sqrt{Hypotenuse^2 - Base^2}[/tex]
By putting values
[tex]Perpendicular = \sqrt{17^2 - 8^2}[/tex]
[tex]Perpendicular = \sqrt{289 - 64} \\\\Perpendicular = \sqrt{225} \\\\Perpendicular = 15[/tex]
Height of wall = 15 feet

x = - 10
One hundred forty-four of the 180 seventh-grade students attended the school dance last Saturday night. What percentage of seventh-grade students did NOT attend the dance?
Answer:
20%
Step-by-step explanation:
Because 144 OUT OF the 180 seventh grade students attended, this would represent 144/180.
But since we are trying to solve how many did NOT attend the dance, you must subtract 144 from 180 which equals 36. So 36/180 did not attend the dance.
But to make it a percentage, you divide 36/180. Fraction and percentage are like buddies! That's why it is very simple to make a fraction into a percentage.
36/180 can be simplified to 1/5, which as a decimal, is 0.20.
0.20 is same as 20%, so this should be the students that did not attend the dance.
I hope this helps. If this is wrong, I truly apologize...

Help? 11 3/4 is the quotient of a number y and 6 1/4
Answer:
y divided by 6 1/4 = 11 3/4
Step-by-step explanation:
First, change the mixed numbers into improper fractions:
y divided by 25/4 = 47/4
Next, multiply both sides by 25/4:
y divided by 25/4 x 25/4 = 47/4 x 25/4
The 25/4's on the left side of the equation cancel each other out, leaving you with:
y = 47/4 x 25/4
Multiply 47 x 25 and keep the same denominator:
y = 1,175/4
Divide and:
y = 293 3/4
Use the diagram to the right to solve for y.
A y = 13

(7,−8) and (x,-5) with a slope of -3/4
I have to find the value of X
Answer:
we have
slope=(-5--8)/(x-7)
-3/4=3/(x-7)
-3(x-7)=3×4
-3x+21=12
21-12=3x
3x=9
x=9/3=3
Answer:
x = 3
Step-by-step explanation:
slope = [tex]\frac{y_{2} - y_{1} }{x_{2} -x_{1} }[/tex]
Using the your two points the slope = m = [tex]\frac{-8 + 5}{7-x} = \frac{-3}{4}[/tex]
[tex]\frac{-3}{7-x} =\frac{-3}{4}[/tex]
Since the numerators are equal, then the denominators must be equal.
So, 7 - x = 4
-x = -3
x = 3
