Answer:
1/4
Step-by-step explanation:
Use the slope formula to find the slope.
slope = (y2-y1)/(x2-x1)
slope = -1 - -2 / -2- -6
= 1/4

B) 5.34 units
C) 6.38 units
D) 9.06 units
Answer:
6.38 is correct
Step-by-step explanation:
i took the test
The measure of the side length DE is 6.38 units.
Option C is correct.
What is a right-angle triangle?There are three angles in the triangle: two sharp angles and one 90-degree angle. The hypotenuse, perpendicular, and base are the names of the sides of a right-angled triangle.
We have,
Triangle DEF contains right angle E. If angle D measures 50° and its opposite side measures 7.6 units,
Applying the tan ratio in the right-angle triangle:
tan50 = EF/DE
tan50 = 7.6/DE
DE = 7.6/tan50
DE = 6.377
DE ≈ 6.38 units
Thus, the measure of the side length DE is 6.38 units.

Answer:
40
Step-by-step explanation:
2/150 can be simplified to 1/75
this means that for every 75 products, 1 will be a defect.
divide 3000 by 75 and you will have your answer.
3000/75 =40.
it is likely there will be 40 defects
another method for this:
1/75 = ?/3000
75 x 40 = 3000 (this means that the denominators are equal. now we must multiply the top number by the same thing)
1x40 = 40.

The circumference of a circle is 19 pi meters. What is the radius in meters?
Answer:
Area = π·r^2 = 3.14·9.5^2 = 283.5 square meters(*)
Area of a circle in terms of diameter:
Area = π·(d/2)^2 = 3.14·(19/2)^2 = 3.14·(9.5)^2 = 283.5 square meters(*)
Area of a circle in terms of the circumference:
Area = C^2/4π = 59.69^2/4π = 3562.9/(4·3.14) = 3562.9/12.56 = 283.5 square meters(*)

Answer:
Part A:
- angle ACB= 60° (ABC equilateral triangle.)
- Angle ECD=EDC= (180°-32°)/2= 148/2= 74° (sum of angles in a triangle is equal to 180, and triangle ECD is isosceles since it's given that CE=DE.
- x= 180°-(60°+74°)

The programmer can type 55 words per minute. At that rate, how many words can the programmer type in 11 min? 66 words 550 words 605 words 655 words.
Answer:
605 minutes
Step-by-step explanation:
We are told that the programmer can type 55 words per minute.
So 55 words = 1 minute
To calculate the number of words the programmer can type in 11 minutes (maintaining the same rate), then we need to multiply the number of words he can type in 1 minute by 11:
55 x 11 = 605 minutes
In 11 minutes he typed 605 words.
GivenThe programmer can type 55 words per minute.
How to find the words type in 11 minutes?In order to achieve the words that a programmer could type, multiply the given 11 minutes to the conversion factor.
In 1 min he types 55 words.
Therefore.
The words typed in 11 minutes is;
[tex]= 11 \times 55\\\\= 605[/tex]
Hence, In 11 minutes he typed 605 words.

The model y = 420x + 720 approximates the worldwide credit card fraud losses from 1989 and 1993, where x = 0 corresponds to 1989, x = 1 corresponds to 1990, and so on, and y is in millions of dollars. What would be the approximate amount of credit card losses in 1994? remember to include the word millions
Answer:
2820 millions
Step-by-step explanation:
1. First, we need to find the value of x by subtract 1989 from 1994.
[tex]1994-1989[/tex] [tex]5[/tex]2. Next, we plug in the variable of 5 and simplify.
[tex]y = 420(5) + 720[/tex] [tex]y = 2100 + 720[/tex] [tex]y = 2820[/tex] 2820 millionsTherefore, the answer is 2820 millions.

The amount of credit card losses in 1994 is 2,820 millions.
What is linear equation?An equation is a statement that two mathematical expressions with one or more variables are equal. A linear equation is one in which the highest power of the variable is 1.
Mathematically: a form of an algebraic equation that can be written as ax + b = 0 or ax + by + c = 0, where a, b, and c are real numbers and x and y are variables of power one.
Given y = 420x + 720
approximates the worldwide credit card fraud losses from 1989 and 1993, where x = 0 corresponds to 1989, x = 1
at 1994 x = 5
since 1994 - 1989 = 5 so x = 5
y = 420x + 720
y = 420 × 5 + 720
y = 2,820 millions
Hence the amount loss is 2,820 millions.
