Answer:
-16
Step-by-step explanation:
So you want to change the - into a + and the negative sign before the 13 also into a plus. So it is -29 + 13 and that would be -16 ^.^ Hope this helped!!
Answer:
Dan will have $1,531.53 after 5 years.
Step-by-step explanation:
To find the answer, you can use the following formula to calculate the future value:
F= P(1 + r)^t
F= Future value
P= Present value= 1200
r= rate of interest= 5%
t= time= 5
F=1200(1+0.05)^5
A=1200(1.05)^5
A=1531.53
According to this, the answer is that Dan will have $1,531.53 after 5 years.
Answer:
x = 330 and y = 40
Step-by-step explanation:
Answer:
Figure 1's surface area: 550 
Figure 2's surface area: 530
Figure 3's surface area: 790
So, the order of the figures' surface areas is: Figure 2 < Figure 1 < Figure 3.
Step-by-step explanation:
Bearing in mind that the surface area of a 3D object is the total area of its surface (that is the sum of the areas of its faces), we can count the number of distinct shapes in each figure, calculate their areas and add them up. Be careful not to add the faces that are "inside".
<u>Figure 1</u>
Its surface area consists of 13 squares of 5x5
and 3 rectangles of 15x5. So, its surface area is (13x25 + 3x75)
<u />
<u>Figure 2</u>
Its surface area consists of 6 squares of 5x5, 3 rectangles of 17x5, 1 rectangle of 13x5 and 2 triangles of base 12 feet and height 5 feet. So, its surface area is (17x5x3+6x5x5+13x5+12x5x2:2)
<u />
<u>Figure 3</u>
Its surface area consists of 2 rectangles of 12.5x5
, 1 rectangle of 11x5, 2 triangles of base 12 feet and height 5 feet, 1 rectangle of 11x13, 2 rectangles of 12.5x11 and 1 rectangle of 12x11.
So, its surface area is (2x12.5x5+11x5+2x12x5:2+11x13+2x12.5x11+12x11)

Step-by-step explanation:
the second one, of course.
a y-intercept is a point where x = 0.
the 2 options are clearly having y-values of -2 and +2.
