What are the coordinates of point A?
A. (0,-4)
B. (-4,0)
C. (4,0)
D. (0,4)
What are the coordinates of point A? A. (0,-4) B. - 1

Answers

Answer 1
Answer:

Answer:

(0,-4)

Step-by-step explanation:

The x coordinate comes first in the ordered pair

We do not move left or right from the origin so the x coordinate is zero

The y coordinate is second, we move 4 units down so the y coordinate is negative 4

The ordered pair is (0,-4)
Answer 2
Answer: 0,-4 coordinates of point A

Complementary angles are two angles that have measures with a sum of 90°. Angles P and Q are complementary and the measure of angle P is 6° more than twice the measure of angle Q.Write a system of equations and use substitution to find the measures of angles P and Q.

Input Field 1 of 1

Answers

Answer:

P = 62°   Q = 28°

Step-by-step explanation:

Let x = measure of angle Q

then y = measure of angle P

Now  x + y = 90  and 2x + 6 = y

Substituting 2x + 6 from the second equation in for y in the first equation, we get x + 2x + 6 = 90 since the two angles are complementary.

3x + 6 = 90

3x = 84

x = 28

y = 2(28) + 6 = 56 + 6 = 62

Check:  28 + 62 = 90

Final answer:

To find the measures of complementary angles P and Q, we set up a system of equations based on the problem's information, solve for one variable, then substitute that variable's value into the other equation. After solving, we find that the measure of angle P is 62°, and the measure of angle Q is 28°.

Explanation:

Let's denote the measure of angle Q as 'q'. Therefore, the measure of angle P can be expressed as '2q + 6'. Now, we can set up two equations based on the information given:

  1. P + Q = 90°, or in terms of 'q', (2q + 6) + q = 90°
  2. P = 2Q + 6°, or in terms of 'q', (2q + 6) = 2q + 6

Solving the first equation gives us 3q + 6 = 90. Subtract 6 from each side of the equation to get 3q = 84. Divide each side by 3 to solve for 'q', and we find that q = 28°. Substituting q = 28° into equation 2, we find that P = 2*28 + 6 = 62°. So, angle P is 62° and angle Q is 28°.

Yuto and Riko went for a bike ride on the same path. When Riko left their house, Yuto was 5.25 miles along the path. If Yuto’s average speed was 0.25 miles per minute and Riko’s average speed was 0.35 miles per minute, then Riko will be behind Yuto when 0 ≤ t < 52.5, where t is time in minutes. Explain what this solution means and why t cannot be less than zero.

Answers

Riko will be behind Yuto when 0 ≤ t < 52.5.

This means for the first 52.5 minutes, Riko will be behind Yuto as he started late. At 52.5th minute Riko will cross Yuto and move ahead because average speed of Yuto is larger than average speed of Riko.

So for first 52.5 minutes, Yuto takes the lead and for the remaining time Riko takes the lead on the path.

t represents time in the given scenario. Time cannot have negative values, it can only be zero or have some positive value. Therefore, t cannot be less than 0. When t is equal to 0 it indicates the start of journey. 
The solution means that Riko will be behind Yuto until they both reach 52.5 miles, t cannot be zero because is the time spent since they both left home.

It will take five builders 62 days to complete a particular project. At this rate, how long would the project take if there were only two builders?(SHOW WORK)

Answers

Answer:

2 builder complete work = 155 days

Step-by-step explanation:

Given:

5 builder complete work = 62 days

So,

1 builder complete work = 62 days × 5

if,

2 builder complete work = [62 days × 5] / 2

2 builder complete work = 155 days
