Lisa wants to frame her little brothers drawing as a gift to her mother.the rectangle drawing is 43.5 centimeters by 934 millime

konstantin123 [22]

Answer:

Lisa will need $273.8\ cm$ of wood framing

Step-by-step explanation:

we know that

The perimeter of rectangle is equal to

$P=2(b+h)$

In this problem we have

$b=43.5\ cm$

$h=934\ mm$

convert to cm

Remember that $1\ cm=10\ mm$

$h=934\ mm=934/10=93.4\ cm$

substitute the values and solve the perimeter

$P=2(43.5+93.4)=273.8\ cm$

Which EST graph correctly represents the information on the table

garik1379 [7]

Answer:

the first one

Step-by-step explanation:

A graph showing the Earliest Start Times (EST) for project tasks is computed left to right based on the predecessor task durations. For dependent tasks, the earliest start time will be the latest of the finish times of predecessor tasks.

The first graph appears to appropriately represent the table values, using edges to represent task duration, and bubble numbers to represent start times.

The second graph does not appropriately account for duration of predecessor tasks.

The third graph seems to incorrectly compute task completion times (even if you assume that the edge/bubble number swap is acceptable).

Does anyone know this?

"c" is the hypotenuse of the largest triangle, and "a" is that triangle's shortest side. Thus the ratio is

... (longest side)/(shortest side)

Since all the triangles in the figure are similar, to complete the proportion, you need to recognize the triangle that "a" is the longest side of, then find the shortest side of that triangle.

"a" is the longest side (hypotenuse) of the smallest triangle. The shortest side of that triangle is "r". So, your proportion is ...

... c/a = a/r

The appropriate choice is the 2nd one, ...

... r

Find all angles, 0 ≤C<360 that satisfy the equation below, to the nearest tenth of a degree.

ludmilkaskok [199]

Move all the terms involving the sine to one side, and all the numbers to the other:

$9\sin(c)-2=\sin(c)-7 \iff 8\sin(c) = -5\iff \sin(c)=-\dfrac{5}{8} \iff c = \arcsin\left(-\dfrac{5}{8}\right)\approx 321.3$
