One angle is 5 degrees less than three times the degree measure of another angle. Together the angles measures have a sum of 143. What is the measure of each angle.

Answers

Answer:

Another angle = 37° and First angle = 3(37)-5 = 106°

Step-by-step explanation:

Let the measure of another angle is x°.

First angle is 5 degrees less than three times the degree measure of another angle = 3x-5

Together the measures of angles have a sum of 143.

ATQ,

x+3x-5 = 143

Taking like terms together,

x+3x = 143+5

4x = 148

x = 37

Another angle = 37°

First angle = 3(37)-5 = 106°

Hence, this is the required solution.

The solution is Option C.

The area of the rectangle is given by the equation A = 1/4 feet²

What is the Area of a Rectangle?

The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle

Area of Rectangle = Length x Width

Given data ,

Let the area of the rectangle be represented as A

Now , the equation will be

Let the length of the rectangle be L

The value of L = 5/8 feet

Let the width of the rectangle be W

The value of W = 4/9 feet

Area of Rectangle = Length x Width

The measure of Length L = 5/8 ≈ 1/2

The measure of Width W = 4/9 ≈ 1/2

Substituting the values in the equation , we get

Area of Rectangle A = 1/2 x 1/2

Area of Rectangle A = 1/4 feet²

Therefore , the value of A is 1/4 feet²

Hence , the area of rectangle is 1/4 feet²

-La altura de una caja es el cuádruple de su ancho y de su largo.
-Si su volumen es de 500 cm3
- ¿Cuáles son las dimensiones de la caja?

Answers

Answer:

Las dimensiones de la caja son:

ancho: 5 cmlargo: igual al ancho: 5 cmaltura: 20 cm

Step-by-step explanation:

Un prisma es un poliedro que consta de dos caras iguales y paralelas llamadas bases, y de caras laterales que son paralelogramos. En el caso en que las caras laterales sean rectangulares, se llama prisma rectangular.

El volumen de la caja, un prisma restangular, se calcula como el área de la base multiplicado por la altura. El área de la base se halla por la fórmula del área del cuadrado: lado multiplicado por lado, es decir, ancho por largo.

En este caso:

ancho: xlargo: igual al ancho= xaltura: cuádruple de ancho y largo= 4*x

Entonces:

Volumen=x*x*4*x

Volumen=4*x³

Si su volumen es de 500 cm³, entonces:

500 cm³=4*x³

Resolviendo:

[tex]x^{3} =\frac{500 cm^{3} }{4}[/tex]

x³= 125 cm³

x=∛125 cm³

x= 5 cm

Entonces, las dimensiones de la caja son:

ancho: 5 cmlargo: igual al ancho: 5 cmaltura: 4*5cm= 20 cm

The city of Stockport received 24 inches of rain last year.

One-fourth of it came in November, and one-third of it came in March.

How much rain came during the other 10 months of the year?

Answers

Answer:

5/12 of rain came, or 10 inches

Step-by-step explanation:

complete rain be 1

then, =1-(1/4+1/3)

=1-(3+4/12) take lcm

=1-7/12

=12-7/12 again lcm

= 5/12

or

1/4 of 24 inches means 1/4×24= 6 inches

1/3 of 24 inches, then 1/3×24= 8 inches

therefore, rest of the months get

= 24-(6+8)

=24-14

=10 inches
