An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 25 inches, and the length of the base is 20 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.
Check the picture below.
The perimeter of the given triangle is 73.8 inches.
What is the perimeter of a triangle?The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.
The length of the altitude is 25 inches, and the length of the base is 20 inches.
Using the Pythagoras theorem, to find the hypotenuse of the triangle :
Hypotenus = √(25² + (20/2)²)
Hypotenus = √(625+ 100) = √725= 26.9 inches
The perimeter of a triangle :
(base + side 1 + side 2) = (20 + 26.9 + 26.9 ) = 73.8 inches
Therefore, the perimeter of the triangle is 73.8 inches.

Indicate whether x and y show direct variation.
3 + y = 5x
Answer:
Let's understand the solution in detail.
Explanation:
Given: 5x = 3y
We can rearrange it as y = 5x / 3
Hence, we see that y ∝ x, and the equation is of the form y = kx, where k is the proportionality constant. This denotes that y varies directly with x.
Here k = 5 / 3.
Hence, the equation represents a direct variation, and the constant of variation is k = 5 / 3.

The scale is:
200 miles ⇒ 5 inchesWe need to find the length of 50 miles represented by x inches on a map.
50 mile ⇒ x inchesBased on he above we can set ratio:
200/50 = 5/xThis can be rewritten as cross-product:
200*x = 5*50The solution is:
x = 250/200x = 1.25 inchesAny proportion we same outcome for x is correct choice.

c) There are 32 students in a class. If the ratio of the number of boys and girls is 5:3, find the number of boys and girls.
Answer:
The no. of boys = 20
The no. of girls = 12
Step-by-step explanation:
Ratio of no. of boys to girls = 5 : 3
[5 multiplied with something, and 3 multiplied with something, added together makes 32.Thus, that something = x]
5x + 3x = 32
= 8x = 32
=x = 32÷8 = 4
5x = 5 x 4 = 20
3x = 3 x 4 = 12
boys : girls = 5 : 3 (total ratio = 8)
boys = 5/8 x 32 = 20
girls = 3/8 x 32 = 12

20y-4x=100
Answer:
[tex]y = \frac{1}{5}x + 5[/tex]
Step-by-step explanation:
20y - 4x = 100
20y= 4x + 100
Divide everything by 20
20y/20 = y
4x/20 = 1/5x
100/20 = 5
y = 1/5x + 5 (that's the answer)
[tex]20y - 4x = 100\\20y = 4x + 100\\\frac{20y}{20} = \frac{4x}{20} +\frac{100}{20} \\y= \frac{1}{5}x +5[/tex]

The probability of the fair spinner landing only once on yellow in two spins is 0.375. Option C is the correct option.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
As, the probability of an event can not be more than the number 1.
Thus, the probability of failure of a event is equal to the difference of the 1 to the success of the event. As,

In the figure shown, L is the center of the circle and PQ is a chord of the circle measuring 20 cm.
What is the length, in cm, of PL? Round to the nearest hundredth digit.
Show me:
(a) length of segment PM (1 point)
(b) what circle property did you use to find the length of PM (1 point)
(c) what formula/theorem did you use to calculate the length of segment PL (1 point)
(d) all math used to calculate the length of segment PL (1 point)
Round your answer to the nearest hundredth digit.
The value of PM is the circle is about 11.66 cm
What is Pythagoras theorem?
Pythagoras theorem is used to show the relationship between the sides of a right angled triangle.
From the diagram:
PM = PQ/2 = 20 / 2 = 10 cm
Hence, using Pythagoras:
PL² = LM² + MP²
PL² = 6² + 10²
PL = 11.66 cm
The value of PM is the circle is about 11.66 cm
