Answer:
3, 15
Step-by-step explanation:
1/10 of a unit also just means dividing by 10. 1/2 is just dividing by 2. Hope this helped!
Answer:
1
Step-by-step explanation:
Given table:
x -1 1 3 5
y -2 0 2 4
Unknown:
Slope of the line = ?
Solution:
Each x and y pair on the table lies on the line. Therefore, we can use them to find the slope;
Slope =
let us take;
x₁ = -1 x₂ = 3
y₁ = -2 y₂ = 2
Insert the parameters and solve;
Slope = = = 1
The slope of the line is 1
Step-by-step explanation:
x=33 y= -22
52 -33
-22=33m+b
-33=52+b
-11=19m
m=-11/19
-22= 19.105+ b
b= -41.105
y=-11x/19 -41.105
x intercept when y=0
0=-11x/19 -41.105
41.105=-11x/19
-11x= 780.995=781
x= - 71
x-intercept = -71
First of all, let's find the dimensions of your triangle. The middle length of the ratio is 4, so the scale factor is (12 cm)/4 = 3 cm. Thus the other two side lengths are 3×3 cm = 9 cm, and 5×3 cm = 15 cm.
The area of a triangle is the same no matter how you compute it. If you compute it using the legs of the right triangle, you find it is
A = (1/2)×(12 cm)×(9 cm) = 54 cm²
If you compute it using the hypotenuse and the height to the hypotenuse, it is the same.
A = 54 cm² = (1/2)×(15 cm)×height
We solve this for height by dividing by the coefficient of height. Doing so, we find
height = (54 cm²)/(7.5 cm) = 7.2 cm
The height to the hypotenuse is 7.2 cm.
