Answer 1

Given:

The side lengths of two cubes are 2.5 yd and 2 yd.

To find:

The side length of third cube.

Solution:

From the given figure it is clear that the cubes are inclined to each other in such a way so that they form a right angle triangle and side length of third cube is the base.

Let x be the side length of the third cube.

Using Pythagoras theorem, we get

[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]

[tex](2.5)^2=(x)^2+(2)^2[/tex]

[tex]6.25=x^2+4[/tex]

[tex]6.25-4=x^2[/tex]

[tex]2.25=x^2[/tex]

Taking square root on both sides, we get

[tex]x=\pm\sqrt{2.25}[/tex]

[tex]x=\pm 1.5[/tex]

Side cannot be negative. So,

[tex]x=1.5[/tex]

Therefore, the side length of the third cube is [tex]x=1.5[/tex] yd.

There are 31 fish in a tank. The fish are either orange or red. There are 7 more orange fish than the number of red fish. How many fish are orange? How many fish are red?

Answers

Answer:

There are 12 red fish, 19 orange fish

Step-by-step explanation:

Let y rep amount of red fish

y + 7 = Amount of orange fish

y + y + 7 = 31

2y = 31 - 7

2y = 24

y = 12

Then

y + 7

12 + 7 = 19

What are similar triangles?

If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.

Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides

Given data ,

Let the first triangle be represented as A B C

Let the second triangle be represented as D E F

Now , the measure of side A D = measure of side D B

And , the measure of side A F = measure of side F C

The measure of side D F = 14

The measure of side D E = 10

The triangles ABC and DEF are similar triangles

From the Triangle segment theorem ,

D F = B C / 2

Substituting the values in the equation , we get

14 = B C / 2

Multiply by 2 on both sides of the equation , we get

The measure of side BC of triangle = 28

Hence , the measure of side B C is 28

The area of the parallelogram is 5 times
the area of the triangle and its perpendicular
height is h cm.
Find the value of h.

The triangle is 7cm across and 24cm up and the parallelogram is 30cm across

Answers

Answer:

14 cm

Step-by-step explanation:

Given that:

Base, b of triangle = 5 cm

Height, H of triangle = 24 cm

Base of parallelogram, a = 30 cm

Area of triangle = 0.5 * bH

Area of parallelogram = a * h

Where, h = height of parallelogram

Area of parallelogram is 5 times the area of triangle ;

5 * 0.5 * 7 * 24 = 30 * h

420 = 30* h

h = 420 / 30

h = 14 cm

Nesesito de su alluda para aclarar esto porfa En una familia son 3 hermana desidieron c0ntratar internet por 9 meses cada mes se les cobra 300 pesos dos de ellas pagaron cuatro meses cada una pago 1200 y la otra pago solo un mes que son 300 pesos si ban por partes iguales entonses cuanto lestoca pagar alas tres y cuando se le renvolsara a ados de ellas que pagaron 1200 cada una

Answers

Answer:

Cada hermana debe pagar $900.

A las dos hermanas que pagaron $1,200 se les reembolsarán $300.

Step-by-step explanation:

Dado que el costo mensual del servicio de internet cuesta $300 por mes, y que el mismo fue contratado por 9 meses por 3 hermanas que se comprometieron a pagarlo en partes iguales, el costo total del servicio será de $2,700 (300 x 9), y cada hermana deberá pagar $900 (2,700 / 3).

Así, si dos de las hermanas pagaron $1,200 cada una, la tercer hermana les deberá reembolsar $300 a cada una de ellas (1,200 - 300).

Answers

To find the area of a triangle, you have to multiply the height and the base length, and divide that by two.

In this question, the height is 3 square units and the base length is 4 square units.

Therefore, to find the area, you must multiply 3 by 4, which is 12, and then divide this by 2, which is 6.

So the area of this triangle is 6 square units.

Given the figure below, calculate its perimeter.

Answers

Answer:

24.58

Step-by-step explanation:

In the big triangle, you see two little triangle

one of the little triangle is a 45-45-90 triangle (the number represent the angle measures of the triangle)

this means that the legs are the triangle can be considered one, and the hypotenuse can be considered [tex]\sqrt{2}[/tex]

so in any 45-45-90 triangle, if you have a leg that is 4, then you know the other leg is also 4, and the hypotenuse would be 4 times [tex]\sqrt{2}[/tex] (aka 5.65)

the other triangle is a 30-60-90 triangle (the number represent the angle measures of the triangle)

this means that the smallest leg of the triangle can be considered one, and the other leg (the bigger one) can be considered 2, and the hypotenuse can be considered [tex]\sqrt{3}[/tex]

so the smallest leg here is 4, this means that the other leg would be 2 times 4 (aka 8)

and the hypotenuse would be 4 times [tex]\sqrt{3}[/tex] (aka 6.93)

so the sides that count to the perimeter of the given triangle would be 4, 5.65, 8, and 6.93

add those up and you get: 24.58
