Answer:
C.
x > 22
Step-by-step explanation:
Deena has already taken 126 calls
She takes 7 calls per hour ( think slope)
y = mx+b
y = 7x+126
She needs to take at least 280 calls. So what she does must be greater than 280
280 <7x+126
We need to isolate x. The first step is to subtract 126 from each side
280-126 < 7x + 126 -126
154 < 7x
Next, we divide by 7 on each side
154/7 < 7x/7
22 < x
Answer:
the vertex angle = 80°
Step-by-step explanation:
V: vertex angle B: base angle
V / B = 8 / 5
5V = 8B
V + 2B = 180
4V + 8B = 720
4V + 5V = 720
9V = 720
V = 80°
check: B = (180 - 80) / 2 = 50°
V / B = 80 / 50 = 8 /5 (8 : 5)
Answer:
25
Step-by-step explanation:
Since AC is similar to CE, we can say that they have equal lengths. We are given CE, DE, and BC. To solve this, we can solve for the length of CE (equal to AC) and then subtract that from BC.
To solve for CE, we are given DE and CE. We know that DE is 1/2 of CE because D is the midpoint of CE. Therefore,
7x-1 = 1/2(10x+18)
expand
7x-1 = 5x + 9
add 1 to both sides to separate the 7x
7x = 5x + 10
subtract 5x from both sides to separate the x
2x = 10
divide both sides by 2 to separate the x
x=5
Therefore, DE = 7(5)-1 = 34 and CE = 10(5) + 18 = 68 = AC.
Using x=5, we know that BC = 9(5) -2 = 43
Therefore, AB = AC-BC = 68-43 = 25
You have to move the decimal back two place in order to get a number between 1-10. So 6.55 X 10^-2
The differences between the given locations ovtained by taking the absolute value of the difference between two points:
- A and B = 202.25 meters
- B and C = 1686.6 meters
- C and D = 474.875 meters
The question involves calculating the difference in the distance between two points.
Location A = - 895.9 m
Location B = - 1098 3/20 = - 1098.15 m
Location C = - 2784.75
Location D = - 3259 5/8 = - 3259.625
Difference between Location A and B
- |-895.9 - (-1098.15)| = 202.25 meters
Difference between Location B and Location C
- |-1098.15 - (-2784.75)| = 1686.6 meters
Difference between Location C and Location D
- |-2784.75 - (-3259.625)| = 474.875 meters
The differences between the different locations are :
- A and B = 202.25 meters
- B and C = 1686.6 meters
- C and D = 474.875 meters
