Answer:
a
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the perpendicular height )
Here b = 9 and h = 12 , then
A = × 9 × 12 = × 108 = 54 cm²
Answer:
r > 7 (C)
Step-by-step explanation:
3r−7>14
Step 1: Add 7 to both sides.
3r−7+7>14+7
3r>21
Step 2: Divide both sides by 3.
3r
3
>
21
3
r>7
Hope this helps and makes sense!! Good luck and have a wonderful day! <33
Imagine this < as a alligater and itś eating the greater number!!
. The number is either 10^1 or 10^3 or 10^ 5 or . . . .
<span>If it is more than 10, then it is not 10^1. The next possibility is 10^3which is 1000, which has factors 2, 5, 10, 20, 25, 40, 50, 80, . . . . . </span>
<span>What constitutes a "multiplication sentence" exactly ? This is not a standard mathematical term. Do you mean "reduce it to its prime factors" ? </span>
<span>1000 = 2 x 2 x 2 x 5 x 5 x 5 </span>
<span>which is a lot more than 4 factors. Or not, if you write it as 2³ x 5³. </span>
<span>But you could say the same about 100 000 = 2^5 x 5^5 </span>
<span>or about 10 000 000 = 2^7 x 5^7 </span>
<span>Take your pick. This is a very badly stated question. </span>
Answer:
Step-by-step explanation:
<u>slope-intercept </u><u>form</u>
y= mx +c, where m is the slope and c is the y-intercept
Given line: y= 2x +2
slope= 2
The product of the slopes of perpendicular lines is -1. Let the slope of the unknown line be m.
m(2)= -1
m= -1 ÷2
m= -½
Substitute the value of m into the equation:
y= -½x +c
To find the value of c, substitute a pair of coordinates.
When x= 4, y= 3,
3= -½(4) +c
3= -2 +c
c= 3 +2
c= 5
Thus, the equation of the line is y= -½x +5.
