Answer:
using the formula x/a + y/b =1
a: slope intercept on the x axis
b:slope intersect on the y axis
x/0 + y/3 = 1 (since x/0 is undefined ,the slope doesn't exist and it is impossible for a slope to be linear)
Answer:
I not sure what the question is
Step-by-step explanation:
By definition, the slope is the inclination of a line in relation to the horizontal. It can be expressed in degrees, ratios and even in percent. Therefore, you can calculate it by applying the following formula:
P%=(H/L)x100
P% is the slope expressed in percent.
H is the height (H=1.2 meters).
L is the length (L=4 meters).
When you substitute these values into the formula P%=(H/L)x100, you obtain the slope of the skateboard ramp:
P%=(H/L)x100
P%=(1.2 meter/4 meters)x100
P%=0.30x100
P%=30%
Answer:
<h2>The correct answer for this question is 78.</h2>
Step-by-step explanation:
- The average or mean of any variable or mathematical phenomenon is calculated as the division of the sum of all the numbers or items within the particular variable by the total number of items or numbers within the variable.
- In this case, the marks of the 4 exams in the semester are 77,90,85 and 100 respectively.There are total 5 exams in the semester.
- Let's suppose that the marks for the 5th exam is x.
- Therefore, based on the mathematical formula to compute average or mean,to get an overall average of 86 including all the 5 exams, one has to get:-




- Hence, based on the above calculations,one has has to get 78 on the 5th exam to obtain an overall average of exactly 86.
as the horizontal beam are parallel to each other x and 40 are alternate angles and alternate angles are equal. So <u>x=40</u>
