Step-by-step explanation:

A: false. since there are 10 girls in mrs. bovine's class, and the number that they are asking is an odd number, it is impossible to say true. the same with the boys, since there are 18 boys and 18 is an even number and what they are asking is also an odd number.

B: true. if we add all the total students together, the total is 26 students. the ratio is a simplified one, and 26 is also the second multiple of 13. there are 14 boys in the class, and 14 is <em>also</em> the second multiple of 7!

C: false. although 10 is the fifth multiple of 2, 15 is the <em>third</em> multiple of five. alas, this problem is not correct.

D. false. 16 is not a multiple of 3, but 28 is a multiple of 7.

a rectangle has an area of 7/8 square units if the width is 7/16 unit what is the length of the rectangle in units?
djyliett [7]

Answer:

Length=2 units

Step-by-step explanation:

Given :

Area of the rectangle =\frac{7}{8}  square units

Width of the rectangle=\frac{7}{16} units

Area of the rectangle= Length* Width

                         \frac{7}{8} =Length*\frac{7}{16}

Multiplying  \frac{16}{7} both the sides

                      \frac{7}{8} *\frac{16}{7} =Length

                     Length=\frac{16}{8}

                   Length=2 units

The length of the rectangle is 2 units

Escribe un número de tres cifras digamos a1b1c1, en el cual a1 sea distinto de c1; ahora invierte los dígitos a1 y c1, (obtendrá
Delicious77 [7]

Answer:

El número obtenido es:

  • <u>1089</u>.

Step-by-step explanation:

Vamos a escoger tres números sencillos para cada variable como:

  • a1 = 1
  • b1 = 2
  • c1 = 3

Por lo tanto, nuestro número de tres cifras es:

  • 123 (la única pauta es que a1 sea diferente a c1 y con este número la cumplimos)

Ahora, nos dice que invirtamos los números a1 y c1, por lo tanto, nuestro nuevo número de tres cifras sería:

  • 321

A continuación, nos menciona que restemos el menor del mayor, en este caso, nuestro número menor es 123 y el mayor es 321, por lo tanto:

  • 321 - 123 = <u>198</u> (Este resultado será el mismo sin importar cuáles números elijas para el ejercicio)

Como obtuvimos el número 198, se podría decir que:

  • a2 = 1
  • b2 = 9
  • c2 = 8

Ahora nos piden que invirtamos a2 y c2, por lo tanto nuestro nuevo número sería:

  • <u>891</u>

Y por último, nos solicita que sumemos los dos últimos números obtenidos, entonces tenemos:

  • 891 + 198 = <u>1089</u>

Por lo tanto, <u>el número obtenido al final es 1089</u>, el cual obtendrás sin importar qué número de tres cifras elijas al inicio, siempre y cuando no se repitan el primero y el tercer dígito.

Which is the equation of the graph
oksano4ka [1.4K]
I'm guessing the last value you have down there that got cut off was the one we want.  We need to set up the general form of the absolute value equation and then solve it for a:  y=a[x-h]+k.  I have no absolute value symbols so I just used brackets.  We have a vertex (h, k) of (0, 0) and I picked a point on the graph to use as my x and y coordinates (4, 3).  Let's fill in the equation now:  0=a[0-4]+3.  We will subtract 3 from both sides leaving -3 = a[-4].  The absolute value of -4 is 4 so now we have -3 = 4a.  Divide by 4 to solve for a.  a=- \frac{3}{4}.  So our equation is y=- \frac{3}{4}[x]
