Answer:
For the box that you did not fill out the area of that shape is 190 sq units
Step-by-step explanation:
10 x 5 = 50 ÷ 2 = 25
10 x 15 = 150
10 x 3 = 30 ÷ 2 = 15
25 + 150 + 15 = 190
Answer:
Every week, the mass of the sample is multiplied by a factor of 0.81
Step-by-step explanation:
Let's rewrite the base and find the expression whose exponent is just ttt.
(0.97)7t+5=(0.97)7t⋅(0.97)5=(0.977)t⋅(0.97)5
Therefore, we can rewrite the modeling function as follows.
M(t)=(0.97)5⋅(0.977)t
According to this model, the mass of the sample is multiplied by 0.977 every week. Rounding this to two decimal places, we get 0.977≈0.81.
Answer:$270
Step-by-step explanation:
I=PRT
Interest=principal times rate times time
Principal=1500
Rate=9%=0.09
Time=2
I=1500 times 0.09 times 2
I=1500 times 0.18
I=270
Interest=270
Total is 1500+270=1770 total paid
Answer:
196 
Step-by-step explanation:
Surface are of 2 rectangles = 2(2*4) = 16
surface are of the base rectangle = 4*3 = 12
Area of tow triangles =2( 
* 2* 2)= 4
total = 16+12+4
= 196
Let's apply the formula giving the slope:
m=(y2-y1) /(x2-x1) , let's plug:
m= (8-0) / (3-(-1)) ====> m= 2
