Answer:
1.7
Step-by-step explanation:
To find the distance between two coordinates, use the formula [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex].
y2 = 4, y1 = 9, x2 = -1, x1 = 2
Insert the values into the equation:
[tex]\frac{4-9}{-1-2}[/tex]
Simplify:
[tex]\frac{4-9}{-1-2}= \frac{-5}{-3}=\frac{5}{3}[/tex][tex]\frac{}{} =1.7[/tex]
The distance between (2, 9) and (-1, 4), rounded to the nearest 10th, is 1.7.

A) acute
B) obtuse
C) right
D) not a triangle
Answer:
Step-by-step explanation:
The sum of the two smaller sides of a triangle must be less than the longest side

Answer:
(a) She is 280m from her starting position
(b) 200m west then 80m south
Step-by-step explanation:
(a) 80m + 200m
= 280m
(b) First she walked 80m north n 200 east
If she want to get back to her starting position she will have to travel the same distance in the opposite direction
Opposite of East is West n opposite north is south
so she will have to go 200m west n then 80m south
What is the distance from -7 to 5 on a number line?
2
4
-12
12
Answer:
12 units
Step-by-step explanation:
Find the absolute value of the difference , that is
d = | - 7 - 5 | = | - 12 | = 12 or
d = | 5 - (- 7) | = | 5 + 7 | = | 12 | = 12
The distance from -7 to 5 on a number line is 12 units. This distance between two integers is calculated by using a number line and the absolute value of the difference between those two integers.
What is a Number line?A number line is a graph for the real numbers.It is used to represent the integers on it at a regular interval. It is also used for finding arithmetic operations like the addition and subtraction of integers.The positive integers lie on the right side of the number line and the negative integers lie on the left side of the line The zero lies at the center of the line which separates the positive and negative integers.How to calculate the distance between two integers on a number line?For calculating the distance between two integers, count every integer in between themA faster way of finding the distance between the two integers is by taking the absolute value of their differenceIf A and B are two integers, then the distance between them is given by |B - A|Calculating the distance from -7 to 5 on the number line:
⇒ | 5 - (-7) |
⇒ | 12 |
= 12 units
Therefore, there are 12 units in between the given two integers -7 and 5 on a number line which is shown below

Answer:
44.1 degrees
Step-by-step explanation:
In this diagram we are given the hypotenuse (39) and the side adjacent to the angle x. The cosine function relates the hypotenuse and adjacent side as follows:
cos x = 28/39
Using the inverse cosine function on a calculator, we get x = 0.7699 radian, which converts to degrees if we multiply this result by 180/π:
Angle x, in degrees, is 44.1 degrees, which is to the nearest tenth.

Each year 50 new bulbs are added, so the gardener can expect that many added plants each year. So add 50 6 times and that will get to how many new bulbs will be added by 10 years time. More and more plants will be added each year and depending on which method the gardener chooses to use it will affect the buying amounts for each year as well as how many are bought.

4x + 8 - 9x = -17 what is x\
and the x has to be the same for each
Answer:
x = 5
Step-by-step explanation:
4x + 8 - 9x = -17
combine like terms:
-5x = -25
divide both sides of the equation by -5:
x = 5
Answer:
x=5
Step-by-step explanation:
4x-9x+8=-17
-5x+8=-17
subtract 8 from both sides and you get:
-5x=25
divide 5 from both sides, and you get x=5! :)

how do you multiply add and divide fractions?
Answer:
If the denominators are not the same: First, make them the same. Then add or subtract like fractions with the same denominators.
Step-by-step explanation:
the first step when multiplying fractions is to multiply the two numerators. the second step is to multiply the two denominators. simplify the new fractions. the fractions can also be simplified before multiplying by factoring out common factors in the numerator and denominator.
to add or subtract fractions they must have the same denominator. if the denominators are already the same then it is just a matter of either adding or subtracting the numerators if the denominators are difrent then a common denominator needs to be found.
