Answer:
88 cm²
Step-by-step explanation:
Each square is 1 cm². Count the squares of each face and add them.
Front face (purple): 14 cm²
Back face (hidden): 14 cm²
Right lower face (orange): 6 cm²
Right upper face (orange): 6 cm²
Left face (hidden): 12 cm²
Upper top face (blue): 3 cm²
Lower top face (blue): 15 cm²
Bottom face (hidden): 18 cm²
Add all areas above:
88 cm²
Answer:
Jake has <em>$11.29 </em>dollars left.
Step-by-step explanation:
To find the answer, we will add up<em> $5 + $6.50 + $7.21</em> and we get<em> $18.71</em>. Now <em>subtract $30 from 18.71</em>, which is <em>$11.29</em>. Therefore, <em>Jake has $11.29 dollars left.</em>
The point-slope form:
We have:
Substitute:
Answer: C. y - 5 = 3(x + 1)
Problem 7: Correct
Problem 8: Correct
Problem 9: Correct
The steps are below if you are curious
===========================================================================================
Problem 7
S = 180*(n-2)
2340 = 180*(n-2)
2340/180 = n-2
13 = n-2
n-2 = 13
n = 13+2
n = 15
I'm using n in place of lowercase s, but the idea is the same. If anything, it is better to use n for the number of sides since S already stands for the sum of the interior angles. I'm not sure why your teacher decided to swap things like that.
===========================================================================================
Problem 8
First find y
y+116 = 180
y+116-116 = 180-116
y = 64
which is then used to find x. The quadrilateral angles add up to 180*(n-2) = 180*(4-2) = 360 degrees
Add up the 4 angles, set the sum equal to 360, solve for x
x+y+125+72 = 360
x+64+125+72 = 360 ... substitution (plug in y = 64)
x+261 = 360
x+261-261 = 360-261
x = 99
===========================================================================================
Problem 9
With any polygon, the sum of the exterior angles is always 360 degrees
The first two exterior angles add to 264. The missing exterior angle is x
x+264 = 360
x+264-264 = 360-264
x = 96
