Step-by-step explanation: divided 135 bultos entre 15 bancas, te da 9, entonces 9 x 9 son 81

Tenemos un problema simple sobre algebra.

Encontraremos que para constrir 9 bancas se necesitan 81 bultos de cemento.

La información dada es:

Se necesitan 135 bultos de cemento para construir 15 bancas.

Entonces la cantidad de bultos que se necesitan para cada banca está dada por el cociente entre la cantidad de bultos usados y la cantidad de bancas que salen de eso.

Esto es:

135/15 = 9

Es decir cada banca necesita 9 bultos de cemento.

Por lo tanto, para construir 9 bancas se necesitaran 9 veces 9 bultos de cemento:

9×9 = 81 bultos de cemento.

Answer:

2.9

Step-by-step explanation:

9 is in the tens place, and 3 is in the hundreds place. If the number in the hundreds place is less than the number in the tens place, the tens place stays the same. You just shorten the number.

So 2.932789 becomes 2.9

Answer:

The interior angle would measure [tex]108^{\circ}[/tex]. Assuming that this polygon is regular, it would contain [tex]5[/tex] sides.

Step-by-step explanation:

An exterior angle in a polygon is supplementary with the interior angle that shares the same vertex with the exterior angle. In other words, the sum of these two angles would be [tex]180^{\circ}[/tex].

In this question, the exterior angle measures [tex]72^{\circ}[/tex]. Therefore, the interior angle that shares the same vertex with this [tex]72^{\circ}\![/tex] exterior angle would measure [tex](180^{\circ} - 72^{\circ})[/tex], which is [tex]108^{\circ}[/tex].

The sum of all interior angles in a polygon with [tex]n[/tex] sides (regular or not) is [tex]180\, (n - 2)[/tex] degrees.

All the interior angles in a regular polygon are equal. Hence, in a regular polygon with [tex]n[/tex] sides (and hence [tex]n\![/tex] vertices,) each of the [tex]n\!\![/tex] interior angles would measure [tex]180\, (n - 2) / n[/tex] degrees.

Assume that the polygon in this question is regular. Again, let [tex]n[/tex] be the number of sides in this polygon. Each interior angle would measure [tex]180\, (n - 2) / n[/tex] degrees. However, it was also deduced that an interior angle of this polygon measures [tex]108^{\circ}[/tex]. That is:

[tex]\displaystyle \frac{180 \, (n - 2)}{n} = 108[/tex].

Solve for [tex]n[/tex]:

[tex]180\, n - 2 \times 180 = 108\, n[/tex].

[tex](180 - 108)\, n = 360[/tex].

[tex]\begin{aligned}n &= \frac{360}{180 -108} \\ &= \frac{360}{72} \\ &= 5\end{aligned}[/tex].

In other words, if this polygon is regular, it would contain [tex]5[/tex] sides.

Answer:

79,000 because its in the middle

Step-by-step explanation:

The number, 78,950, rounded to the nearest hundred is: 79,000.

The third digit in a number represents the hundred of the number. If the number is greater than 5, round it up.

The hundred digit in 78,950 is 9, rounding it up will give us: 79,000.

Therefore, 78,950, rounded to the nearest hundred is: 79,000.

Answer:

D

Step-by-step explanation:

2x. add 8 to other side. you get 2x=12

The correct answer would be an option (D) 2x = 12 which correctly uses the division property to begin solving the equation: 2x − 8 = 4

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that performs the arithmetic operations are called arithmetic operators.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have given the equation as

⇒ 2x − 8 = 4

⇒ 2x = 4 + 8

⇒ 2x  = 12

⇒ x  = 12/2

Apply the division operation on both sides

⇒ x = 6

Hence, the correct answer would be an option (D) 2x = 12 that correctly uses the division property to begin solving the equation: 2x − 8 = 4

Answer:

9

Step-by-step explanation:

Since it is a straight line, therefore it will always be 180°

So...

(8v +3) +105 = 180

8v + 3 + 105 = 180

8v = 180 - 108

V = 72/8

= 9

Answer:

[tex]\boxed {\boxed {\sf v=9}}[/tex]

Step-by-step explanation:

In the diagram, there are 2 angles: 105° and (8v+3)°. They are on a straight line together, so they are supplementary angles. They must add to 180 degrees. We can set up an equation.

[tex]105 + (8v+3) = 180[/tex]

We are solving for v, so we must isolate the variable. First, we can rearrange the right side and combine the like terms (the constants without a variable).

[tex]105 +8v+3= 180 \\8v + (105+3) = 180 \\8v + 108= 180[/tex]

108 is being added to 8v. The inverse operation of addition is subtraction. Subtract 108 from both sides of the equation.

[tex]8v+108-108= 180-108 \\8v= 180-108 \\8v=72[/tex]

v is being multiplied by 8. The inverse operation of multiplication is division. Divide both sides by 8.

[tex]\frac {8v}{8}= \frac{72}{8}\\[/tex]

[tex]v= \frac{72}{8}[/tex]

[tex]v=9[/tex]

v is equal to 9.
