Answer:
1.125
Step-by-step explanation:
Of means multiply
2.5% * 45
Change the percent to decimal form
.025 * 45
1.125
17 bc it's in the middle (btw I didn't make that up my teacher in 6th grade said that)
Here is an example:
3(4x +7)
2( 3 +5) =2( 3 ) = 2 ( 5 )
The solution to the given equation is w = -5
<h3>Solving of expression</h3>
What is an Algebraic Expression? An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations
Given the expression below as shown;
-10w = 50
Divide both sides by -10
-10w/-10 = 50/-10
w = -5
Hence the solution to the given equation is w = -5

Answer:
a. 6, b. 99, c. 63
Step-by-step explanation:
A) The function s(t) is in the vertex form. The standard vertex form is a(x-h)+k where the vertex is (h,k). The vertex is the highest (or lowest in some cases) point of the graph, so if we use s(t) to get the vertex we get that h=6 and k=99. This means that for a student to get a perfect score they need to study 6 hours
B) We can just take the k value from the first question because that's the highest value for s(t), so the highest score will be 99
C) For this one just plug in 0 for time, so -(0-6)^2+99. This equals -(-6)^2+99, which equals 99-36 =63
