1. Use the figure below to answer the questions.

olasank [31]

Answer:

Step-by-step explanation:

The 3D shape shown in the image is a prism, known because it has two parallel faces called bases (the front and back triangles) and the other faces being parallelograms.

To compute the total surface area, we must add the area of the five faces of the shape.

For the bases:

$\displaystyle A_b=2\cdot \frac{bh}{2}=bh$

For the upper face

$A_u=z.w$

Where z is the hypotenuse of the triangle and w is the depth of the prism.

For the face-down surface

$A_d=b.w$

For the right face

$A_r=h.w$

The total area is

$A=bh+zw+bw+hw=bh+w(z+b+h)$

$A=4\times 3+11(5+3+4)=12+132=144$

$A=144\ cm^2$

11. An old machine requires three times as many hours to complete a job as

valentinak56 [21]

Answer:

Step-by-step explanation:

$9(r_n+r_o)=1\\ \\ r_n+r_o=\frac{1}{9}\\ \\ r_o=\frac{r_n}{3}\\ \\ r_n+\frac{r_n}{3}=\frac{1}{9}\\ \\ \frac{4r}{3}=\frac{1}{9}\\ \\ 4r=\frac{1}{3}\\ \\ r=\frac{1}{12}\\ \\ \text{So working alone it would take the new machine 12 hours to finish the job.}$

Round each mixed number to the nearest whole number. Then, estimate the quotient.

Anni [7]

You would round up because 24 16/17 is closer to 25 and 4 8/9 is closer to 5.
which would be 25/5 which estimates to 5.
