A triangle has angle measures
x+15, 3x-35, and 4x.
What type of triangle is it? Be as specific as possible. Justify your answer.

Answers

Answer 1
All angles in the triangle add up to 180 degrees. So,
(x+15) + (3x-35) + 4x = 180
8x - 20 = 180
8x = 200
x = 25

First angle : x+15 = 25+15 = 40 degrees
Second angle: 3x-35 = 3 * 25 - 35 = 40 degrees
Third angle: 4x = 4 * 25 = 100 degrees.

It is an isosceles triangle since it has two angles (the first end the second one) equal to each other.

Hope that helps :)

The slope of the line is 0. It passes through the point (-3,4). Identify two other points on the line. Justify you answer

Answers

Answer:

Two other points: (2, 4) (6, 4)

Step-by-step explanation:

A line with a slope = 0 is a horizontal line [with a y-intercept of (0, b)], given by the linear equation, y = 4.  This means that the y-coordinate will always equal to 4, regardless of its corresponding x-coordinate. Basically, we could choose any x-coordinate to pair with the y-coordinate of 4.

I chose the ordered pairs, (2, 4) and (6, 4).

Attached is a screenshot of the graphed linear equation, y = 4.

Terry’s average driving speed for a 2 and a half hour trip was 58 mph. How far did Terry travel?

Answers

Is it is multiplication it is 116 in division 29

145 miles. lets see how i got this.

so first i took the 2.5 hour trip and the average speed, which was 58 mph (or 93.3 kph), and multiplied them together, because of the rule of d=rt.

sidenote: also if you want to find the speed, use r=d/t. also, for finding the time, use the t=d/r rule.

side-sidenote: i hope this answers your question and helps you in the future.

key: r= rate (mph or kph), d=distance, and t=time.

A shipment of sugar fills
4/9 containers. If each container holds 2 2/5
tons of sugar, what is the amount of sugar in the entire shipment?
Write your answer as a mixed number in simplest form.

Answers

Answer:

For this problem, multiply these fractions.

 

First, make each one an improper fraction: 2 4/5 is the same as 14/5 and 2 3/7 is the same as 17/7.

 

Now, 14/5 times 17/7 yields 238/35 which reduces to 34/5. This may be expressed also as the mixed fraction 6 4/5.

 

So, the shipment contains 6 4/5 tons of sugar. (This is also equal to 13,600 pounds of sugar.)

It is 8+783 to the 2 power
the y-intercept is the point on the graph where it crosses the y-axis, and has coordinates (0, b). It is also the value of y when x = 0.

To find the y-intercept, set x = 0:

y = -3/4(0) - 4

y = 0 - 4

y = -4.

Therefore, the y-intercept is (0, -4), or -4.
