The polygons
are similar. Find the value of x.
10
2x - 19
7
14
14
answer:
14 is two times greater than 7.
so,
10 is two times greater than 2x - 19
10 = 2(2x - 19)
10 = 4x - 38
48 = 4x
x = 12

The Jones have some friends drop in. They wish to serve sherry but do not have enough to serve all the same kind. So they mix some which is 20% alcohol with some which is 14% alcohol and have 5 quarts, which is 16% alcohol. How much of each king of sherry they have to mix
Answer:
they have to mix 1.67 quarts 20% and 3.33 quarts 14%
Step-by-step explanation:
Given the data in the question;
let x quarts of the 20 percent alcohol and y quarts of 14 percent alcohol be mixed to form 5 quarts
i.e
x + y = 5 -------------let this be equation 1
20%x + 14%y = 16%5
0.2x + 0.14y = 0.8
multiply through by 50
10x + 7y = 40 -------------let this be equ 2
so let multiply equation by -7
-7x - 7y = -35 ------------- let this be equ 3
add equ 2 and 3
3x + 0 = 5
x = 5/3 ≈ 1.67
substitute value of x in equation 1
5/3 + y = 5
y = 5 - 5/3
y = 10/3 ≈ 3.33
Therefore; they have to mix 1.67 quarts 20% and 3.33 quarts 14%
2 divide by 531

what is the least whole number that has the remainders 10,12, and 15 when divided by 16, 18. and 21, respectively
Answer:
[tex]1002[/tex]
Step-by-step explanation:
First find difference between the divisors and remainders.
[tex]16-10=6\\18-12=6\\21-15=6[/tex]
Here, the difference between the divisors and remainders is equal.
So, the required number is equal to LCM of [tex](16,18,21)-6[/tex]
[tex]16=2^4\\18=2(3^2)\\21=3(7)[/tex]
LCM of [tex](16,18,21)=2^4(3^2)(7)=1008[/tex]
Required Number [tex]=1008-6=1002[/tex]
