Solve For C.40 + 2 &lt; 10AALs

Answers

Answer 1

Answer:

c < 2

Step-by-step explanation:

We have an inequality and are asked to solve for the variable "c."

4c + 2 < 10

To solve for c, we need to get it by itself, isolate it in every way possible.

4c + 2 < 10

Subtract 2 from both sides :

4c < 8

Now before we move on, take this into consideration, sometimes the inequality sign can be switched but under one condition. And that is when you divide both sides by a negative, since we are not dividing by a negative, no switch of the sign is needed.

Divide 4 from both sides to get c alone :

c < 2

John lays tile for a living. While trying to create the perfect design for his client, he then drew this pattern containing two right angles and an isosceles triangle.

For the triangles to fit together perfectly, John must determine the measure of angles 1, 2, and 3.

Answers

Answer:

Angle 1= 58

Angle 2= 64

Angle 3= 58

Step-by-step explanation:

The two smaller triangles are each right triangles and every triangle equals 180 so add 32 degrees and 90 degrees ( 90+32=122) and subtract that from 180 and you get angles 1 and 3 from your isosceles triangle

then you add both angles 1 and 3 from your isosceles triangle which are 58 degrees each (58+58=116) and subtract that from 180 (180-116=64) and you get angle 2

Answer:

angle 1 = 32

angle 2 = 116

angle 3 = 32

Amrita is 8 years elder to her brother Aman. If the ratio of their ages is 7 : 3, find their present ages?​

Answers

Answer:

Amrita = 14 years old

Aman = 6 years old

Step-by-step explanation:

Find out the difference of the units.

7 - 3 = 4

Amrita is 4 units/8 years older than Aman.

4 units = 8

1 unit = 8 ÷ 4 = 2

Amrita is 7 units and her brother is 3 units.

Amrita = 7 units x 2 = 14

Aman = 3 units x 2 = 6

Answers

Answer:

a) $654

b) 27 unidades cuadradas

c) 721

Step-by-step explanation:

a) ¿Cuál es el valor de un bolígrafo cuando la docena se compra por $ 7848?

Una docena = 12

Por eso:

12 bolígrafos = $ 7848

1 bolígrafo = $ x

Cruz multiplicar

12 bolígrafos × $ x = 1 bolígrafo × $ 7848

$ x = 1 bolígrafo × $ 7848/12

$ x = $654

b) Área de un triángulo ¿9 unidades de base y 6 unidades de altura?

Área de un triángulo =

= 1/2 × Base × Altura

1/2 × 9 × 6

= 27 unidades cuadradas

c) Cien veces la suma de 4.5 con 2.71

Esto se calcula como:

100 × (4,5 + 2,71)

= 100 × (7.21)

= 721

What is the measure of all exterior angles of a pentagon

Answers

Answer:

72 degrees for each exterior angle and 360 degrees for all of them summed.

Step-by-step explanation:

An exterior angle of a polygon is the angle between the line extending one of its sides and the next side.  As you go around a regular n sided polygon doing this, you will rotate through a complete circle of 360 degrees.  All these angles are equal, so each one is 360/n.

For the pentagon, n=5, so the sum of all its exterior angles is 360 degrees and each exterior angle is 360/5=72 degrees.

It's C.

Basically, when youre dividing something, the bases would stay the same but the exponents would change. For division, you'd have to substract the exponent of the denominator from the denominator (of like bases, of course)

In this case, it's 10^8-(-3).

The only reason it's not 10⁵ is because of the negative 3. If it were a positive 3, it would become 10⁵.
