Answer: 4.5 gallons
Step-by-step explanation:
From the question, Chanasia has 11.25 gallons of paint and she wants to use 2/5 of the paint to paint her living room.
The number of gallons of paint that Chanasia will use would be calculated by multiplying the fraction by the total gallons of paint. This will be:
= 2/5 × 11.25
= 0.4 × 11.25
= 4.5 gallons
Answer:
126
Step-by-step explanation:
42% of 100 in 42
100x3=300 soooo
42x3=126
The equation
can be used to find the measure of ∠BAC ⇒ 2nd answer
Step-by-step explanation:
Let us revise the trigonometry ratios in the right triangle ABC, where B is the right angle, AC is the hypotenuse, AB and BC are the legs of the triangle
The trigonometry ratios of the ∠BAC, the opposite side to this angle is BC and the adjacent side to it is AB are
In Δ ABC
∵ ∠ BCA is a right angle
∴ The hypotenuse is AB
∵ The adjacent side to ∠CAB is AC
∵ The opposite side to ∠CAB is BC
∵ AB = 13 units ⇒ hypotenuse
∵ CB = 12 units ⇒ opposite
∵ AC = 5 units ⇒ adjacent
- Let us find the trigonometry ratios of angle BAC
∵ m∠CAB is x
∵ 
∴ 
∴ 
∵
∴ 
∴
