Answer:
Step-by-step explanation:
It is given that A 14 foot ladder is leaning against a building. The ladder makes a 45 degree angle with the building, then let AC=14 foot and ∠C=45°and AB be the length of the building.
Thus, using the trigonometry, we have
Substituting the given values, we get
⇒
⇒
⇒
⇒
Thus, the length of the building will be .
Answer:
£25
Step-by-step explanation:
total distance travelled per week = 2 * 7.5 * 5 = 75
amount of fuel used = 75/30 = 2.5 gallons = 11.375 litre
cost of fuel = 11.375 * 1.14 = 12.9675
total cost = 5(2.5) + 12.9675 = 25.4675 ~~ 25
The answer is
C = 4 ÷ 1/5
Rule: y = kx (y varies directly with x)
Then 12=k(3), and k=4. Then the rule (direct variation) becomes y=4x.
Now let x=10. Then y=4(10) = 40 (answer)
