Answer:
yes; x=7
Step-by-step explanation:
When two corresponding angles are congruent, all angles are congruent, so the triangles are similar. The sides of the triangle on the right are 30/25 = 6/5 times the length of the sides of the left triangle, so side MP will be 6/5 times the length of JL, or (6/5)·20 = 24.
Then the expression for that length lets us find the value of x:
24 = 4x -4
6 = x -1 . . . . . divide by 4
7 = x . . . . . . . add 1
Answer: B. x=10
Step-by-step explanation:
<u>Concept</u>
- If it is an isosceles triangle, then the altitude would also be the median of the base, meaning that it divides the base evenly.
- We are going to use the Pythagorean theorem which is a²+b²=c², where [a] and [b] are legs, and [c] is the hypotenuse.
<u>Given</u>
Hypotenuse (relative) = √74
Altitude (one leg) = 7
The other leg (half of the base) = x/2
<u>Solve</u>
a² + b² = c²
(7)² + (x/2)² = (√74)²
49 + x²/4 = 74
x²/4 = 25
x² = 100
x = 10
Hope this helps!! :)

Answer: 24times
Step-by-step explanation:
Formula for the volume of a cylinder = πr²h
Volume of the cone = 1/3πr²h
Therefore the volume of the cylinder = 22/7 x 10² x 20
= 22/7 x 10 x 10 x 20
= 6285.71cm³
Therefore , the volume of the cone = 1/3 x 22/7 x 5² x 10
= 1/3 x 22/7 x 5 x 5 10
= 5500/21
= 261.9cm³
Therefore the number of times needed to use the completely filled cone to completely filled the cylinder with water = 6285.71/261.9
= 24times.
Answer:
y = 5x - 4
Step-by-step explanation:
5 is the slope so it goes in front of the x and -4 is the y Intercept so it goes last.
