Answer:
- A: 700
- B: he put the decimal point in the wrong place
Step-by-step explanation:
Part A: The problem 49/0.07 can be rewritten as 4900/7 by multiplying numerator and denominator by 100. Then it is more clear that the correct answer is (49/7)×100 = 700.
___
Part B: I've always had trouble reading Marco's mind, so I cannot tell you what mistake he made. I can tell you the decimal point in his result is in the wrong place.
Answer:
x= 13/2
Step-by-step explanation:
multiply 4x4+4x3-9x2-x+2=x-1
calculate 16+12-18-x+2=x-1
move the terms 12-x=x-1
collect like terms calculate -x-x=-1-12
divide both sides -2x=-13
solution x=13/2

Bettie's claim is not reasonable.
The expression will be given as h(8) = -0.3(8-5)²+7.5 the value of the function h(8) will be 6.3 feet.
<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that:-
- The function is h(x) = -0.3( x - 8)² +7.5
Now from the question when the boy jumped from a certain height he lands 8 feet farther away this condition will be expressed in the expression as follows:-
h(x) = -0.3( x - 8)² +7.5
Put x = 8 feet as
h(8) = -0.3(8-5)²+7.5
h(8) = -0.3 ( 3 )² + 7.5
h(8) = -2.7 + 9
h( 8 ) = 6.3 feet
Therefore expression will be given as h(8) = -0.3(8-5)²+7.5 the value of the function h(8) will be 6.3 feet.
