An open box is constructed of 3500 cm2 of cardboard. The box is a cuboid, with height h cm and square base of side x cm. What is the value of x which maximises the volume of the box? Give your answer in cm correct to 3 significant figures.

Answer:

1/4

Step-by-step explanation:

25 goes into 100 four times

a) (150 - 138) / 12 = 1 deviation or 34%

(162 - 150) / 12 = 1 deviation or 34%

34% + 34% = 68%

b) (150 - 126) / 12 = 2 deviations or 47.5%

(174 - 150) / 12 = 2 deviations or 47.5%

47.5% + 47.5% =95%

c) (150 - 126) / 12 = 2 deviations or 47.5%

(162 - 150) / 12 = 1 deviation or 34%

47.5% + 34% = 81.5%

d) (162 - 150) / 12 = 1 deviation or 34%

(174 - 150) / 12 = 2 deviations or 47.5%

This problem is a little different. We have to subtract 34% from 47.5%

47.5% - 34% = 13.5%

Exact Form: 47/50

Decimal Form: 0.94

Queremos encontrar y resolver una expresion algebraica para ver cuantos paquetes necesitamos para empacar los vasos.

La solución es 137 paquetes.

Veamos como obtener la solución.

Cada paquete puede sostener 10 vasos, y tenemos un total de 1367 vasos.

Entonces lo que debemos ver es cuantos grupos de vasos tenemos en 1367, esto será simplemente el cociente entre 1367 y 10.

1367/10 = 136.7

El problema ahora es que no podemos sar un 0.7 de un paquete, así que debemos redondear esto al proximo número entero, que es 137.

Así, podemos concluir que se necesitaran 137 paquetes para empacar los 1367 vasos.

Answer:

14

Step-by-step explanation:

Perimeter= 99

XV+VW+WX=99

4z+3z+1+z+2=99

8z+3=99

8z= 96

z=96/8

z= 12

WX= z+2= 12+2= 14.

Answer:

x = 30 degrees

y = 67 degrees

z = 83 degrees

Step-by-step explanation:

Since x, y , and z are the angle measure for the first, second and third angle respectively, we can write the following equations following the statements given:

The sum of the measures of the angles of a triangle is 180:

(1)   x + y + z = 180

The sum of the measure of the second and third angle is five times the measure of the first angle:

(2)    y + z = 5 x

The third angle is 16 more than the second:

(3)    z = y + 16

Now we solve the system of three equations. We use the third equation to replace z in the second one:

y + (y + 16) = 5 x

then : 2 y = 5 x - 16;   then y = 2.5 x - 8

So , now we can replace this expression for y in the third equation:

z = (2.5 x - 8) +16 = 2.5 x + 8

and finally we made the replacements of y and z shown above in bold, in the first equation:

x + (2.5 x - 8) + (2.5 x + 8) = 180

x + 5 x = 180

6 x = 180

then x = 180/6 = 30 degrees

From this, we get the value of the other angles:

y = 2.5 (30) - 8 = 67 degrees

z = 2.5 (30) +8 = 83 degrees

Answer:

Noelle: 20 Dad: 54

Step-by-step explanation:

The age of Noelle's Dad is 6 less than 3 times Noelle's age looks like this:

d=3n-6

While the sum of their two ages is 74, looks like this:

n+d=74

The system is:

{d=3n−6

{n+d=74

Now, substitute the first equation into the second equation and solve for n.

n+(3n−6)=74

4n-6=74

Add 6 to both sides

4n=80

Divide both sides by 4

n=20 (<---- Noelle's Age!)

Now plug n into the second equation

d=3(20)-6

d=60-6

d=54 (<---- Noelle's Dad's Age!)

THE ANSWER TO THAT PROBLEM IS SIMPLY 175

Answer:

19

Step-by-step explanation:

All you need to do is subtract 78 from 97 to find the "remainder." Or you can also add until you get to 97.

97 - 78 = 19

78 + 19 = 97.
