What is (18x-44 )+(8x-10) =180?

Answer:

14.88 resmas

Step-by-step explanation:

Los maestros de una escuela planean enviar 6 boletines al año a cada una de las 620 familias con estudiantes en la escuela.

Esto significa: El número total de boletines que recibe cada familia = 6 × 620 familias

= La escuela envía 3720 boletines cada año

Cada uno de los boletines necesita 2 hojas de papel.

1 boletín = 2 hojas de papel

3720 boletines =

Cruz multiplicar

3720 boletines × 2 hojas

= Se necesitan 7440 hojas de papel en un año

El papel se vende en resmas de 500 hojas.

¿Cuál es la cantidad mínima de resmas de papel necesarias para imprimir los boletines escolares en un año?

500 hojas de papel = 1 resma

7440 hojas de papel = y

Cruz multiplicar

500 × y = 7440 × 1

y = 7440/500

y = 14.88 resmas

La cantidad mínima de resmas de papel necesarias para imprimir los boletines escolares en un año es 1488 resmas

Answer:

The biker is traveling at [tex]5\frac{1}{3}[/tex] miles per hour.

Step-by-step explanation:

To find the rate, in miles per hour, you must use the formula r = d/t.

(r = rate)

(d = distance)

(t = time)

[tex]\frac{8}{3}[/tex] ÷ [tex]\frac{1}{2}[/tex] = [tex]5\frac{1}{3}[/tex]

Answer:

Sarita’s solution is correct. She made an error in her verification. Sarita was supposed to add the 5 and 7 in the first step.

Step-by-step explanation:

Given the following equation:

The steps to solve it are:

5(x-3)+7(x+4)-73

1. Apply the Distributive property:

5x-15+7x+28=73

2. Add the like terms:

12x+13=73

3. Subtract5 13 from both sides of the equation:

12x+13-(13)=73-(13

12x=60

4. Divide both sides of the equation by 12:

12r/12 = 60/12

x = 5

To verify it, let's substitute  into the equation:

5(5-3)+7(5+4)=73

Evaluating, we get:

5(2)+7(9)=73

10+63=73

73=73

Based on this, we can determine that Sarita's solution is correct, but she made an error in her verification (Observe that 5-3 is not equal to -2 )

Answer:

A. Sarita’s solution is correct. She made an error in her verification.

Yes and No, if you divide 6 by 3, 2, or 1, it will have a quotient less than 6. Dividing 6 by 3 = 2, 6 by 2 = 3, 6 by 1 = 6.

Given sequence:

-2,-7,-12 ,..

Unknown;

Find the sum of the first 20 terms = ?

Solution:

  The sequence is -2,-7,-12 ,..

To find he sum of n-terms of a sequence, we use the expression below;

     Sₙ  = [tex]\frac{n}{2} (2a + (n-1)d)[/tex]

where n is the number of terms = 20

           a is the first term = -2

            d is the common difference= -7 - (-)2 = -5

Now input the parameters and solve;

       Sₙ  = [tex]\frac{20}{2} (2(-2) + (20 - 1) x -5)[/tex]

      Sₙ = 10(-4 + -5(19))  = 10(-99)  = -990

The sum of the first 20 terms of the sequence is -990

No, the ratio of 15:12 is not equivalent to 5:3 and 10:6 because

- 15:12 = 5:4

- 5:3

- 10:6 = 5:3

Given,

5:3 and 10:6 are equivalent ratios.

We need to see whether these ratios are equivalent to 15:12.

The ratios which are equal are called proportional ratios.

Example:

1:2 = 5:10 = 6:12 = 7:14

5/10 = 1/2

6/12 = 1/2

7/14 = 1/2

We have,

5:3 and 10:6

- 5/3

- 10/6 = 5/3

We have,

15:12

= 15/12

= 3x5/3x4

= 5/4

We see that 5:3 and 10:6 are not equivalent to 15:!2.

Thus,

No, the ratio of 15:12 is not equivalent to 5:3 and 10:6 because

- 15:12 = 5:4

- 5:3

- 10:6 = 5:3

Answer:

562 child tickets were sold

217 adult tickets were sold

Step-by-step explanation:

A festival charges $3 for children admission and $5 for adult admission

At the end of the festival they have sold a total number of 779 tickets for $2771

Let x represent the child ticket

Let y represent the adult ticket

x + y= 779..............equation 1

3x + 5y= 2771..........equation 2

From equation 1

x + y = 779

x= 779 -y

Substitute 779-y for x in equation 2

3x + 5y= 2771

3(779-y) + 5y= 2771

2337 - 3y + 5y= 2771

2337 +2y= 2771

2y= 2771 -2337

2y = 434

y = 434/2

y = 217

Substitute 217 for y in equation 1

x + y= 779

x + 217= 779

x = 779-217

x= 562

Hence 562 child tickets were sold and 217 adult tickets were sold

Answer:

[tex]A=28.1\ cm^2[/tex]

Step-by-step explanation:

The area of a circular sector with a central angle θ and radius r is given by:

[tex]\displaystyle A=\frac{1}{2}r^2 \theta[/tex]

Note: The angle must be in radians.

We need to find both the radius and the angle in radians.

Diameter = 9.6 cm

Radius r=Diameter/2=4.8 cm

Angle in radians= Angle in degrees*π / 180

θ = 140*π / 180 = 2.4435 rad

Now we calculate the area:

[tex]\displaystyle A=\frac{1}{2}(4.8)^2 2.4435[/tex]

[tex]\boxed{A=28.1\ cm^2}[/tex]

And the actual answer to the riddle (not answer to expression) is 1 since it only says one was going to saint ives.

Answer:

Step-by-step explanation:

Since, ΔBCM ≅ ΔZYR,

∠B ≅ ∠Z

∠C ≅ ∠Y

∠M ≅ ∠R

And BC ≅ ZY

CM ≅ YR

BM ≅ ZR

a). CM = YR = 11 m

b). BM = RZ = 15 m

c). YZ = BC = 8 m

d). m∠B = m∠Z = 45°

e). m∠M = 180° - [m(∠B) + m(∠C)]

              = 180° - (45 + 103)°

              = 180° - 148°

              = 32°

f). m∠Y = m∠C = 103°

Congruent triangles have equal corresponding sides and angles

The given parameter is:

[tex]\triangle BCM \cong \triangle ZYR[/tex]

This means that triangle BCM and ZYR are congruent.

So, we have the following congruent sides

[tex]YZ =CB[/tex]

[tex]BM =ZR[/tex]

[tex]CM =YR[/tex]

So, the measure of the side lengths are:

[tex]YZ =8[/tex]

[tex]BM =15[/tex]

[tex]CM = 11[/tex]

Also, we have the following congruent angles

[tex]\angle B = \angle Z[/tex]

[tex]\angle C = \angle Y[/tex]

[tex]\angle M = \angle R[/tex]

So, the measure of the angles are

[tex]\angle B =45[/tex]

[tex]\angle Y =103[/tex]

The measure of angle M is calculated using:

[tex]\angle M + \angle C + \angle B = 180[/tex]

So, we have:

[tex]\angle M + 103 + 45= 180[/tex]

[tex]\angle M + 148= 180[/tex]

Subtract 148 from both sides

[tex]\angle M = 32[/tex]
