Answer:
The answer is B. 12 cm
Step-by-step explanation:
ABC is a right triangle
AB and BC are the legs and AC is the hypotenuse.
The Pythagorean theorem a^2 + b^2 = c^2 can be manipulated to solve for a and get 12.
Answer:
0
Step-by-step explanation:
–5(3 – q) + 4 = 5q – 11
-15 +5q + 4 = 5q -11
-11 + 5q = 5q - 11
+5q - 5q = -11 + 11
0=0
Let a,b,c,d and e are five numbers
mean = (a +b+ c+ d+e)/5 = 30
⇒ (a +b+ c+ d+e) = 150_______(1)
now, Let the number excluded be a
then, new mean = (b+ c+ d+e)/4 = 28
⇒ (b+ c+ d+e)= 112
putting this value in (1),
⇒a + 112 = 150
⇒a = 150 -112 = 38
excluded number = 38
Answer:
$44.10
Step-by-step explanation:
$8.40÷2= $4.20 for 1 pound of ground beef
so:
10.5 x $4.20= $44.10
hope that helped :)
Answer:
Step-by-step explanation:
2*x + 3 = 1/2x + 30 Subtract 3 from both sides
<u> - 3 -3</u>
2x = 1/2x + 27 Subtract 1/2 x from both sides
<u>1/2 x -1/2 x</u>
1 1/2 x = 27 change 1 1/2 to 3/2
3/2 x = 27 Multiply by 2/3
2/3 * 3/2x = 27 * 2/3
x = 18
