Answer:
x = 90 , y = 43
Step-by-step explanation:
Since AB and AC are congruent , then Δ ABC is isosceles with base angles congruent , that is
∠ ABD = ∠ ACD = 47°
AD is the perpendicular bisector of BC , so
∠ ADB = x = 90
the sum of the 3 angles in Δ ABD = 180° , then
y = 180° - (90 + 47) = 180 - 137 = 43
Answer:
15 dimes and 10 nickels
Step-by-step explanation:
15 dimes because 15 multiplied by 10 cents is $1.50
10 nickels because 10 multiplied by 5 cents is $0.50
15 x 0.10 = 1.50 10 x 0.50 = 0.50
0.50 + 1.50 = 2.00

Answer:
306.6
Step-by-step explanation:
Solution for 14.6 is what percent of 21:
14.6:21*100 =
(14.6*100):21 =
1460:21 = 69.52380952381
Now we have: 14.6 is what percent of 21 = 69.52380952381
Question: 14.6 is what percent of 21?
Percentage solution with steps:
Step 1: We make the assumption that 21 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that $100\%=21$.
Step 4: In the same vein, $x\%=14.6$.
Step 5: This gives us a pair of simple equations:
$100\%=21(1)$.
$x\%=14.6(2)$.
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have the correct answer
