Wat yo mean by don't solve the bottom
oh well

so we need surface area

we need top rectangle, 2 side triangles, back rectangle and bottom rectangle

top is 5 by 25 and 1/5, the raea is 25 and 1/5 times 5=126 square feet
triangles are the same
but which one is the height?
hmm
I'm going to assume the 25ft is height
so base is 25/12 ft
2 triangles so
2 times 1/2 times 25 times 25/12=625/12 square feet
back
25/12 feet by 5ft or 125/12 ft²

bottom is 25 by 5ft or 125 sqaurefeet


total

126+625/12+125/12+125=627/2 squaer feet or 313.5 sqquare feet
so every hundred needs 1 quart

313.5/100=3.135
round up becase you can't buy 0.135 quart (or can you?)
4 quarts

statuscvo [17]

Answer:

150 hombres juegan baloncesto.

Step-by-step explanation:

En una escuela hay 315 alumnos de los cuales 1/3 son mujeres y el resto son hombres.

Paso 1

Encontramos el número de estudiantes que son mujeres

= 1/3 × 315

= 105 mujeres.

Se nos dice que el resto son hombres. Por lo tanto, el número de hombres que son estudiantes se da como:

= 315 - 105 mujeres

= 210 hombres

Paso 2

2/7 de los hombres juegan fútbol y el resto baloncesto.

Esto significa que 2/7 de 210 hombres juegan al fútbol

= 2/7 × 210 hombres

= 60 hombres

Por tanto, 60 hombres juegan al fútbol.

Paso 3

También se nos dice que el resto juega al baloncesto.

El número de hombres que juegan baloncesto se calcula como:

210 - 60

= 150 hombres.

Por tanto, 150 hombres juegan baloncesto.

To Enter the value of n that makes the equation: 4^5.4^n=4^8 true
irina1246 [14]
4^2\text{ }\times4^n=4^8

Since both sides have the same base (4), we can add the exponents

4^{5+n}=4^85+n=8

subtract 5 from both sides:

5+n-5=8-5n=3

Wiat number should be added to both sides of the equation to complete the square? X^2+x=11
Ivahew [28]

Answer:

add 1/4 to each side

Step-by-step explanation:

x^2+x=11

We take the coefficient of the x term

1

Then divide it by 2

1/2

Then square it

(1/2) ^2 = 1/4

Add this to both sides of the equation

x^2 + x + 1/4 = 11+1/4

(x+1/2)^2 = 11 1/4
