If ∡A ≡ ∡B ∡C ⇒ ΔABC = equilateral ⇒ AB = BC = AC
3x - 5 = 2x + 20
(AB) (BC)
3x - 2x = 20 + 5
x = 25
24 you take 30 and multiply it by 4 and then divide it by 5
<span>The answer has to be "n ≤ 6" because the greatest "n" CAN be is 6, so "n can=6", but it can also be smaller.</span>
Answer:
amount of fabric to make the bag = 4 yards
Step-by-step explanation:
Tara has 1 3/5 yards of fabric . She needs extra 2 1/2 times the amount she have to make a shopping bag. The amount of fabric she needs to make the bag can be calculated as follows.
1 3/5 yards = 8/5 yards of fabrics
What she actually needs to make a shopping bag is two and half the amount she has . Mathematically, it can be express
2 1/2 × 8/5
Let us change 2 1/2 to improper fraction
amount of fabric to make the bag = 5/2 × 8/5
amount of fabric to make the bag = 40/10
amount of fabric to make the bag = 4 yards
Answer:
a)
Step-by-step explanation:
Square root of 75 (√75) is regarded as a surd function because the value inside the square root sign is not a perfect square. In that case the given value will be splitted into the product of a largest perfect square and a prime number as shown:
√75 = √3×25
√75 = √3×√25
√75 = √3 × 5
√75 = 5√3
a) Based on the above calculation, it can be inferred that his reasoning is incorrect. The value of 3 was supposed to be inside a square root not a whole number i.e √3 × √25
b) Since √75 = 5√3
√75 = 5 × 1.7321
√75 = 8.6605
√75 = 8.661 {to nearest thousand}
