Answer:

x = 44/3 = mixed number - 14 2/3

Step-by-step explanation:

Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.

Answer:14.67

Step-by-step explanation:

$\\$ 22/27 = x/ 18

$\\$ cross multiply

$\\$ 27x = 22 x 18

$\\$ 27x = 396

$\\$ x = 396/27

$\\$ x = 14.67

Lin's teacher uses the box to store her set of cubes with an edge length of one half inch. if the box is completely full, how ma

nlexa [21]

Answer:

448 cubes

Step-by-step explanation:

Volume of cubes fitted in the box will be equal to the cumulative volume of the cubes.

Since, volume of a cube = (Side)³

Side of the cube = $\frac{1}{2}$ inch

Therefore, volume of the cube = $(\frac{1}{2})^3=\frac{1}{8}$ inches

Volume of the storage box = 56 cubic inches

Since, number of cubes fitted in the storage box = $\frac{\text{Volume of the storage box}}{\text{Volume of one cube}}$

= $\frac{56}{\frac{1}{8}}$

= 56 × 8

= 448 cubes

Therefore, number of cubes fitted in the storage box = 448

Answer: Slope: -1 Y-intercept: -4

Step-by-step explanation:

Slope formula:

$m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

$m=\frac{-13 -(-6)}{9-2}= m=\frac{-13 + 6}{9-2}$

$m=\frac{-7}{7\\}$

m = -1

When you draw this on the graph, the y-intercept is -4.

y = -4

In remodeling a house an architect finds that by adding the same amount to each dimension of a 15ft by 19ft rectangular room, th

earnstyle [38]

Answer:

Step-by-step explanation:

new length=15+x

width=19+x

then area=(15+x)×(19+x)=285+15x+19x+x²=x²+34x+285 ft²

original area=15×19=285 ft²

then 285+98=x²+34x+285

or

x²+34x-98=0

x²+34x+17²=98+17²

(x+17)²=98+289=387

x+17=√387=3√43

x=3√43-17 ft
