The Rivera family bought a new tent for camping. Their old tent had equal sides of 10 feet and a floor width of 15 feet, as shown in the accompanying diagram. If the new tent is similar in shape to the old tent and has equal sides of 16 feet, how wide is the floor of the new tent?
Answer:
25.6 feet
Brainliest, please!
Step-by-step explanation:
10/16 = 16/x
5/8 = 16/x
5 = 128/x
x = 128/5
x = 25.6
The floor of the new tent is 24 feet wide.
What is ratio?Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b.
Given that,
Side of old tent = 10 feet,
And width of floor = 15 feet.
Let width of new tent is x feet.
To find the width of a tent whose side is 16 feet,
Use ratio and proportion property,
10/15 = 16/x
x = (16 × 15)/10
x = 240/10
x = 24 feet
The width of the floor of the new tent is 24 feet.

7n + 12 = 3n+ 8n
That’s the problem
Answer:
n = 3
Step-by-step explanation:
to find the value of n
we need to transpose
7n + 12 = 3n+ 8n
7n + 12 = 11n
12 = 11n -7n
12 = 4n

"The perimeter of a triangle is 294cm. The sides are x + 2, 2x + 3, and 3x + 1. Find the length of each side of the triangle."
Answer:
50cm, 99cm, 145cm
Step-by-step explanation:
The perimeter is just the distance around the triangle. We have all three sides.
So
(x+2) + (2x + 3) + (3x + 1) = 294
Combine like terms
6x + 6 = 294
Subtract 6 on both sides
6x = 288
Divide 6 on both sides
x = 48
So the sides are
x + 2 = 48 + 2 = 50 cm
2x + 3 = 2(48) + 3 = 96 + 3 = 99 cm
3x + 1 = 3(48) + 1 = 145 cm
Checking, first:
50 + 99 + 145 = 194 cm
Plug in x = 48 to the original equation.
48 + 2 + 2(48) + 3 + 3(48) + 1 = 294
48 + 2 + 96 + 3 + 144 + 1 = 294
294 = 294
The lengths of the sides of the triangle are 50 m, 99 m, and 125 m.
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 sides of triangle are x + 2, 2x + 3, and 3x + 1.
Given that the perimeter of a triangle is 294 cm
Since the perimeter of a triangle is the addition of the lengths of the triangle's three sides.
So the perimeter of a triangle = sum of all sides
⇒ x + 2 + 2x + 3 + 3x + 1 = 294
⇒ 6x = 294 - 6
⇒ x = 288/6
⇒ x = 48
So the length of the first side = 2+48 = 50
So the length of the second side = 2(48 ) +3 = 99
So the length of the second side = 3(48) + 1 = 125
Thus, the lengths of the sides of the triangle are 50 m, 99 m, and 125 m.
