Answer:
(-1/4)(2x +5y)
Step-by-step explanation:
Multiply and divide by -1/4:
Part A:
Company A: $7 per hour +$30 service charge =money spent
Company B: $8 per hour +$40 service charge =money spent
Part B:
Company A: $7(8)+$30 = $86
Company B: $8(8)+$40 = $104
Part C:
Company A: $7(2)+$30 = $44
Company B: $8(2)+$40 = $56
You would save $12 if you use Company A instead of Company B's truck rental.
Multiply the triangles then divide to find the missing number
Answer:
A.
1. 5cm
2. 10cm
3. 20cm
4. 40 cm
Step-by-step explanation:
I think you need to double the area of the scaled factor.
Answer:
6.5 x 10^6 To answer this question, you need to divide the mass of the sun by the mass of mercury. So 2.13525 x 10^30 / 3.285 x 10^23 = ? To do the division, divide the mantissas in the normal fashion 2.13525 / 3.285 = 0.65 And subtract the exponents. 30 - 23 = 7 So you get 0.65 x 10^7 Unless the mantissa is zero, the mantissa must be greater than or equal to 0 and less than 10. So multiply the mantissa by 10 and then subtract 1 from the exponent, giving 6.5 x 10^6 So the sun is 6.5 x 10^6 times as massive as mercury.
