Well first, you want to find their least common multiple, which is 15.
So you want 15 red roses and 15 white roses.
In order to get that, you want 5 packages of red roses, because 3*5=15.
And you’ll want 3 packages of white roses because 5*3=15.
Answer:
See below
Step-by-step explanation:
19)
13² = 4² + AM²
169 = 16 + AM ²
AM ² = 153
AM =√153 = √(9× 17) = 3√17
sinA = MT /AT = 4/13
cosA = AM/AT = (3√17)/13
tanA = MT/AM = 4/(3√17) = (4√17)/51
sinT = AM/AT = (3√17)/13
cosT = MT/AT = 4/13
tanT = AM/MT = (3√17)/4
20)
10² = 5² + AJ²
100 = 25 + AJ²
AJ² = 75
AJ = √75 = √(25×3) = 5√3
sinA = JT/AT = 5/10 = ½
cosA = AJ/AT = (5√3)/10 = (√3)/2
tanA = AJ /AJ = 5/(5√3) = (√3)/3
sinT = AJ/AT = (5√3)/10 = (√3)/2
cosT = AJ/AT = 5/10 = ½
tanT = AJ/JT = (5√3)/5 = √3
Answer:
try doing cross out way
Step-by-step explanation:
Answer:
Extended facts are basic addition facts multiplied by a power of 10, such as 10, 100, 1,000.
Step-by-step explanation:
Example: 7 + 6 = 13 (basic) 70 + 60 = 130 (extended) 700 + 600 = 1300 (extended).
Given that,
An expression : 4(n- 3²) + n
To find,
The equivalent expression.
Solution,
We have,
4(n- 3²) + n
As 3²= 9
= 4(n- 9) + n
Opening the brackets,
= 4n-4(9) + n
= 4n-36 +n
= 5n-36
Hence, the equivalent expression is 5n-36.
