Answer:
A and C
Step-by-step explanation:
Since it is isosceles two sides should be equal and we already know the perimeter is 21in.
<em>5</em>+<em>5</em>+11=21in
5+<em>8</em>+<em>8</em>=21in
Answer:
7^12
Step-by-step explanation:
We know that a^b ÷ a^c = a^(b-c)
7 ^ 14÷ 7^2
7^ (14-2)
7^12
Answer:
(9159 / 7 = 1308.429)
Step-by-step explanation:
Simply multiply the last digit by 2 and then subtract the product from the remaining digits.
If that difference is divisible by 7, then 9159 is divisible by 7.
The last digit in 9159 is 9 and the remaining digits are 915. Thus, the math to determine if 9159 is divisible by 7 using our alternate method is:
915 - (9 x 2) = 897
Since 897 is not divisible by 7, 9159 is also not divisible by 7.
Therefore, the answer to "Is 9159 Divisible By 7?" is no.
(9159 / 7 = 1308.429)
Answer:
x = 233.4 feet
y = 318.3 feet
z = 233.4 feet
Step-by-step explanation:
To find side x, we need angle (a) or angle (b) of the right triangle. In this case it is 45 degrees. We also need the hypotenuse and in this case it is 330 feet.
x = 233.35 feet, rounded to x = 233.4 feet
Side (z) is equal to side (x) because both angles (a) and (b) are 45 degrees.
z = 233.35 feet, rounded to z = 233.4 feet
The value of (a) for the top triangle is 84.93 and the value of (x) is 233.35
84.93+233.35 = 318.28
y = 318.3 feet
