Answer:
x = 26.4
Step-by-step explanation:
Here, we want to get the value of x
To get this, we are to use the appropriate trigonometric ratio
From the question, we have the opposite and the adjacent
The trigonometric ratio to use in this case is the tangent
Mathematically;
Tan 53 = 35/x
x = 35/tan 53
x = 26.37
which is 26.4

what is the difference between associative property,communitive property,and distributive property? (will mark brainliest)
Answers
Answer:
Commutative switches the numbers, while associative keeps the numbers positions but changes the parentheses. I hope that helped
The communities property changes the order only. Example- 3+2 -> 2+3
The distributive property distributes the number from the outside of the parenthesis to the numbers inside
Example- 4(5+3) so you distribute the 4 to the 5 and 3 by multiplying. The answer would be 20+12

Daysi buys a video game on sale. If the video usually costs $30.00, and it
was on sale for 25% off, how much did Daysi pay?
Answers
Answer:
$22.5
Step-by-step explanation:
The original price is $30 and it's on sale for 25% off. Since 25% is a quarter of the total price, I divided 30÷4=7.5. $7.5 is 25% of $30, so 7.5 is the amount taken off the original price. To find what Daysi paid, I subtracted 30-7.5=22.5. $22.5 is the result after the 25% off, so Daysi paid $22.5.

3% is the interest rate. Using the formula I=PRT, you can simply derive the rate by putting the given numbers in.
I = 450P = 3,000R = ?T = 5 Years
The equation now goes,450 = 3,000 * R * 5450 = 15,000 * R450/15,000 = R0.03 = R
multiply it by 100,
R = 3%

Answers
-12y + 16 = 4
-12y = -16
Y = 1.3333333
Answer:
y=1
Step-by-step explanation:
Let's solve your equation step by step.
Step 1: Simplify both sides of the equation.
−4(2y−4)−4y=4
(−4)(2y)+(−4)(−4)+−4y=4(Distribute)
−8y+16+−4y=4
(−8y+−4y)+(16)=4(Combine Like Terms)
−12y+16=4
−12y+16=4
Step 2: Subtract 16 from both sides.
−12y+16−16=4−16
−12y=−12
Step 3: Divide both sides by -12.
y=1
