What is the measurement of a cube’s side with a surface area of 1,350 square feet?

liq [111]

To solve this, we would divided 1,350 by 6, because the cube has 6 sides and the number 1,350 represents all 6 sides added together. 1,350/6 = 225. Therefore, the answer is 225 ft

A rectangle's perimeter and area have the same value. The width of the rectangle is 6 units. What is the length of the rectangle

Sliva [168]

Answer:

The length ot rectangle is 3 units.

Step-by-step explanation:

The formula for perimeter is P = 2l + 2w and the area is A = l×w. Assuming that the perimeter and area have the same values so you have to compare it :

$perimeter = 2l + 2w$

$area= l \times w$

$perimeter = area$

$2l + 2w = lw$

$let \: w = 6$

$2l + 2(6) = 6l$

$2l + 12 = 6l$

$12 = 6l - 2l$

$4l = 12$

$l = 3 \: units$

Select the correct answer. What is the range of the function f(x) = -4\x+ 11 - 5? A. (-4,-5) B. [-5,-) OC. (-4,-) OD. (-2,-4] Re

Y_Kistochka [10]

We are given the following function:

$f(x)=-4\lvert x+1\rvert-5$

This function is equivalent to the function:

$g(x)=-4\lvert x+1\rvert$

Together with a translation 5 units in the negative direction of the "x" axis. Since the range of g(x) is all the values of "y" that are smaller or equal to zero, if we translate 5 units in the negative direction of the y-axis the range is:

$R(f(x))=\mleft\lbrace y\parallel y\mright?\le5\rbrace$

or in interval notation:

$R(f(x))=(-\infty,-5\rbrack$

A store sells Brazilian coffee for $10 per lb. and Columbian coffee for $14 per lb. If the store decides to make a 150-lb. blend

Artemon [7]

Answer:

The store should use 112.5 pounds of Brazilian coffee and 37.5 pounds of Colombian cofee.

Step-by-step explanation:

Let "b" be the amount of Brazilian coffee, in pounds, required for the blend and "c" the amount of Colombian coffee required, in pounds.

Since there are two unknown variables a two-equation system is needed to solve the problem, we can set up one equation for weight and another for price as follows:

$b+c=150\\10*b+14*c=11*150$
