.Answer:
-105
Step-by-step explanation:
Given
for 6 weeks
Required
Represent this as an integer
If the driver spends $105 on his taxi then it means that the money is debited from the driver's bank account.
Debit implies negative and it is represented by a negative symbon
Hence, the integer that represents this scenario is -105
Easy so you have to choose them then add them and yeah hope this helps bbg
Answer:
√113 and in the decimal form it's 10.630
Step-by-step explanation:
Hope this is helpful!
Its udefined because the question asked describe the line of a slope, now its not negative or positive because there is no change. Its undefined because its a line, going vertical way
The length of QR is 44 inches
Step-by-step explanation:
In Δ PQR
- PQ = 39 inches
- PR = 17 inches
- PN is the altitude of it and its length is 15 inches
We need to find QR
To solve this problem we will use Pythagoras Theorem let us revise it
In ΔABC, if b is the right angle, then AC is called the hypotenuse of the Δ, AB , BC are its two legs, the relation between them is:
(AC)² = (AB)² + (BC)²
In Δ PQR
∵ PN is the altitude
∴ PN ⊥ QR
∴ m∠PNQ = m∠PNR = 90°
In ΔPNQ
∵ m∠PNQ = 90° ⇒ proved
- PQ is the hypotenuse
∴ (PQ)² = (PN)² + (NQ)²
∵ PQ = 39 ⇒ given
∵ PN = 15 ⇒ given
- Substitute them in the equation above
∴ (39)² = (15)² + (NQ)²
∴ 1521 = 225 + (NQ)²
- Subtract 225 from both sides
∴ 1296 = (NQ)²
- Take √ for both sides
∴ 36 = NQ
In Δ PNR
∵ m∠PNR = 90° ⇒ proved
- PR is the hypotenuse
∴ (PR)² = (PN)² + (NR)²
∵ PR = 17 ⇒ given
∵ PN = 15 ⇒ given
- Substitute them in the equation above
∴ (17)² = (15)² + (NR)²
∴ 289 = 225 + (NR)²
- Subtract 225 from both sides
∴ 64 = (NR)²
- Take √ for both sides
∴ 8 = NR
∵ QR = NQ + NR
∴ QR = 36 + 8
∴ QR = 44 inches
The length of QR is 44 inches
