Answer:
Step-by-step explanation:
11x^{2}+x^{2}=\left(4x+8\right)\left(3x-3\right)
15/x = 40/100. Cross multiply to get 1500 = 40x. Divide by 40 on both because you want to isolate the variable. The idem would originally cost $37.50. To check your answer you would substitute your equation and get 15/37.5 = 40/100. Just so you know a decimal can be in a fraction. Cross multiply to get 1500 = 1500. <span />
Answer:
MQP = 138
Step-by-step explanation:
Since the angle bisector always divides the angle in half exactly, we know both of the angle measures we have are the same, and set it up like this: 5x + 19 = 2x + 49 (subtract 2x from both sides) 3x + 19 = 49 (subtract 19 on both sides) 3x = 30 (divide by 3) x = 10
Substitute that x value (10) into the original equations in place of x for each angle to get MQN = 69 and NQP = 69
Add the two values to get 138. MQP = 138
Answer: 5.8 cm
Step-by-step explanation:
Given that the chord is 0.8 cm from the center of a circular ring and the radius r = 3 cm
Using pythagorean theorem to find part of the cord
3^2 - 0.8^2
= 9 - 0.64
= 8.36
Square root of the value above gives 2.89
The length of the chord = 2 × 2.89 = 5.782
= 5.8 cm (to the nearest tenth)
