Andrew can reach a maximum of 
high up the wall.
The right-angled triangle formed can be solved using the 
ratio. that is
where 
is the distance from the foot of the wall to the tip of the ladder where it rests on the wall. Substituting, and solving for , we get
Since Andrew can reach an extra 
above the point where the ladder rests against the wall, the maximum height Andrew can paint is

The product of the expression in scientific notation is expressed as 6.45 * 10^-9
<h3>Scientific notations</h3>
The standard scientific notation is expressed as:
A * 10^n
A is any value between 1 and 10
n is any integer
Given the product
(4.3 x 10-7)(1.5 x 10-3)
= (4.3 * 1.5)(10^-7 * 10^-3)
= 64.5 * 10^-10
= 6.45 * 10^-9
Hence the product of the expression in scientific notation is expressed as 6.45 * 10^-9

#SPJ1
the equation of the line is y= x-4
Step-by-step explanation:
so so the first thing that you're going to do is get y alone
-x-5=y
next you're going to find your slope which in this case is negative one.
after that in order to find the equation of a parallel line you're going to find the reciprocal of the slope.
so in this case the reciprocal is one.
next you're going to substitute in the cordinates to find the y intercept
x+b=y. (-1)+b= -5. (. b is the y intercept)
b= -4
The best answer for this question would be:
D. 32
In order to get this, you have to get the sum in the line,
which is the first four people. So the solution would be: 4(23) = 92
For getting the sum of the people in the last 3 would be:
3(34) = 102
Next is the sum of everyone which the solution would be:
6(27) = 162
So the initial solution that we have now would be: F + 92 -
F + 102- F = 162
- F + 194 = 162
- F = 162 - 194
- F = - 32
The (F) here or the fourth person’s age would be= -32 / - 1
or 32
Answer:
x=-25
Step-by-step explanation:
Inverse variation
xy =k
We know x and y
20*5 =k
100 =k
So the formula is
x y = 100
We know y = -4
x (-4) = 100
Divide each side by -4
-4x/-4 = 100/-4
x = -25
