You would know 4×5=20 so just add 2 more zeroes cause there is a zero in 40 and in 50

hope this is what you're looking for and made sense

All you have to do to find 40*50 in your mind, is multiply 4 and 5. Then you will have to add the two 0s at the end. So it will go like 4*5=20+0+0=2,000

six times jasons collection of books and one-third of nathans collection add up to 134 books one-third of jasons collection and

atroni [7]

6j + 1/3n = 134...multiply by 3....18j + n = 402
1/3j + n = 31....multiply by 3....j + 3n = 93

the multiplying by 3 is optional...I just did it because it is easier to work with equations when there are no fractions.

18j + n = 402....multiply by -3
j + 3n = 93
----------------
-54j - 3n = - 1206 (result of multiplying by -3)
j + 3n = 93
----------------add
-53j = - 1113
j = -1113/-53
j = 21

j + 3n = 93
21 + 3n = 93
3n = 93 - 21
3n = 72
n = 72/3
n = 24

so Jasons collection (j) consists of 21 books and Nathans collection (n) consists of 24 books

Answer:

Radius is 2.8 Circumference is 17.584 or 17.6 Rounded to the nearest Tenths 

Step-by-step explanation:

1. Find circumference with the Formula C=πd

C=3.14 x 5.6

C=17.584 or 17.6 Rounded to the nearest Tenths

2. Radius is Always half of the Diameter.

5.6/2 = 2.8

2.8 is your radius.

3. If you want to check you work try the formula C=2πr to see if things checks out.

C=2 x 3.14 x 2.8

C= 17.584 or 17.6 Rounded to the nearest Tenths

Hope this Helps!

Cómo puedo hallar la longitud de un lado de un triángulo usando el teorema del ángulo de 30°

Elza [17]

En un triángulo rectángulo con ángulos de 30° -60° -90°, para encontrar la longitud de un lado, debes encontrar la longitud de la hipotenusa.

<h3 /><h3>¿Cómo encontrar la longitud de la hipotenusa?</h3>

Es necesario encontrar la longitud del cateto opuesto al ángulo de 30°, también conocido como cateto menor, y luego multiplicarlo por 2, descubriendo así el cateto de la hipotenusa, utilizando la fórmula del teorema de Pitágoras:

a²+b²=c²

Por lo tanto, puedes usar el teorema de Pitágoras para calcular la longitud del lado que falta en un triángulo rectángulo.
