Answer:
shipping and handling is <u>18.90</u> dollars
Step-by-step explanation:
percent means "per one hundred", so any percent can be written as a fraction over 100
30% = 30/100 = 0.30
Multiply 0.30 with the price 63 to get 0.30*63 = 18.90, which is the cost of shipping only. This result is added on top of the 63 dollars to get the total cost.
Answer: 25√2 nearest tenth is 35.4
Step-by-step explanation: Phythagorean thrm= 25^2+25^2=(diagonal)^2; diagonal= 25√2. Trig: Sin 45= √2/2; 25/ hyoptenuse = √2/2 hyoptenuse also equals 25√2
<u>Given</u>:
The two angles A and B are vertical angles.
The measure of ∠A is x and the measure of ∠B is 5x - 20.
We need to determine the measure of ∠A.
<u>Value of x:</u>
Since, the angles A and B are vertical angles and the vertical angles are always congruent.
Thus, we have;
Substituting the values, we have;
Adding both sides of the equation by 80, we have;
Thus, the value of x is 20.
<u>Measure of ∠A:</u>
The measure of ∠A can be determined by substituting x = 20 in the measure of angle A.
Thus, we get;
Thus, the measure of ∠A is 20°
