The ratio of the sides of a triangle is 4:6:9. If the perimeter of the triangle is 95 meters,
Grace [21]

Answer:

45 meters

Step-by-step explanation:

Perimeter of the triangle is the sum of the 3 lengths of the traingle. Since the ratio of the sides is 4:6:9, let the shortest side be 4 units, the longest side be 9 units and the 3rd side be 6 units.

Units is represented as u.

Sum of all 3 sides= 95 m

4u +6u +9u= 95

19u= 95

u= 95 ÷19

u= 5 meters

Longest side= 9 units

Length of the longest side= 9(5) = 45m

What is the slope of the line that
kherson [118]

Answer:

The value of the slope is 6

Step-by-step explanation:

To get the slope of the line, we are going to make use of the slope equation

Mathematically, we have this as;

m = (y2-y1)/(x2-x1)

where (x1,y1) = (1,2) and (x2,y2) = (2,8)

Substituting these values;

m = (8-2)/(2-1) = 6/1 = 6

The thickness of a part is to have an upper specification of 0.925 and a lower specification of 0.870 mm. the average of the pro
SVETLANKA909090 [29]
To solve this problem, we make use of the z statistic. The formula for the z score is:z score = (x – u) / swhere x is the sample value = 0.90, u is the sample mean = 0.917, and s is the standard deviation = 0.005
Therefore:z score = (0.90 – 0.917) / 0.005z score = -3.4
From the standard probability tables, the p-value for a right tailed test of z = -3.4 is:P = 0.9997
Therefore there is a 99.97% chance that it will be above 0.90 mm
