Answer:
SA = 52 square meters
Step-by-step explanation:
<em>First, the equation I'll be using for this problem is</em><em> SA=2(wl+hl+hw)</em><em>! Our </em><em>width is 4m, </em><em>our </em><em>length is 3m</em><em>, and our </em><em>height is 2m</em><em>. To begin to solve this problem we are going to input these values in to the equation above.</em>
SA = 2(4 × 3 + 2 × 3 + 2 × 4)
<em>Next, we are going to multiply our values inside the parenthesis based on the </em><em>PEMDAS</em><em> </em><em>strategy</em><em> (if you have any questions about this, feel free to ask below :).</em>
SA = 2(12 + 6 + 8)
<em>Now, we can add our values inside the parenthesis.</em>
SA = 2(26)
<em>Finally, all we have to do is distribute the 2 outside of the parenthesis to inside the parenthesis.</em>
SA = 52 square meters

Answer:
x<15, probably
Step-by-step explanation:
maybe multiply 2 to each side to eliminate the fraction. so 3x+15<60. subtract 15 to isolate the variable term so 3x<45. divide by 3 to isolate x so x<15. check the work. is the inequality true for all values of x less than 15? let's try the first possible integer value, 14, to be sure. 3(14)+15= 57. so 57/2<30. now 57/2 is 28.5 and 28.5<30 so it seems right
Answer:
0.30 of a book / hour or 3/10 of a book per hour.
Step-by-step explanation:
Usually I tell people to put the numbers into decimals. Unfortunately for this question, it won't work. So we have any choice but to do it with fractions.
r = amount / time
amount = 1/4
time = 5/6
r = 
Invert the denominator and multiply
r = 
r = 6 * 1 / (5*4) = 6/20 = 3/10
The answer is 3/10 of a book per hour
5/6 of an hour is almost an hour.
1/4 of a book is 0.25 of a book.
3/10 of a book is 0.30 of a book. So it looks like it is just about right.
Answer:
The correct answer by solving question no 1 is
a=(d-c)/b
Step-by-step explanation:
ab+c=d
or,ab=d-c
Therefore,a=(d-c)/b
Part A:
Express the given number of hours and velocities of the cyclist as ordered pairs. The time (number of hours) can be our abscissa (x-coordinate) and the velocities can be our ordinate (y-coordinate). The coordinates are therefore (2, 18) and (4, 4). The equation that can be formed in this is established through the two-point equation.
(y - y₁) = ((y₂ - y₁)/(x₂ - x₁))(x - x₁)
Substitute the known variables.
(y - 18) = ((4 - 18)/(4 - 2))(x - 2)
Simplifying the equation,
y - 18 = -7(x - 2)
y = -7x + 32
<em>ANSWER: y = -7x + 32
</em>Part B: This can be graph in the Cartesian plane and numbers 1 to 8 can be substituted to y and take note of the ordered pairs for each point. The slope of the line should be -7 and the y-intercept is 32.<em>
