Answer:
<h3>-41</h3>
Step-by-step explanation:
Given the expression written by the teacher as;
-16+(-25)
We are to find the equivalent expression.
Note that +×– = –
Hence;
-16+(-25)
= – 16 – 25
= - 41
Hence the resulting value of the expression is –41
3. slope is 7 (slope = rise/run) count from the left most point to the other
up 7 right 1 both positive so slope = 7/1 reduced is 7
4. slope is 1/3 same process as above
up 1 right 3 both positive movement so slope is 1/3
5. y = 1/3x - 4 slope intercept form is y = (slope)x + (y-intercept)
y-intercept is where the graph touches the y-axis
6. y = 3x + 4
Answer: 4 bags
Step-by-step explanation: since the height of the wooden boxes are 1.5 feet tall and they need the box to be full it will be 4 bags. Also because each bag contains 1.5 feet of dirt and that’s the exact amount we need for one box.
You just simplify it down until to the point where you can't and it should be 3:5
We see that the shape is made up of 2 shapes:
trapezoid and triangle
(trapezoid is on top of upside down triangle)
area of trapezoid=(1/2)(b1+b2)(h)
area of traignel=(1/2)(b)(h)
area of trapezoid
b1=14
b2=18
h= ok so total height=17 and 12 is taken up by triangle os therefor h=17-12=5
A=(1/2)(14+18)(5)
A=(1/2)(32)(5)
A=(16)(5)
A=(80)
now area of triangle
H=12
B=18
A=(1/2)(18)(12)
A=(9)(12)
A=108
add
80+108=188
total area=188mm^2
