What is the width of a rectangle with length 14 cm and area 161cm squared 2

1 answer:

3 0

Length • Width = area. Length is 14. So set it up like an equation. W • 14 = 161. This simplifies to 14W= 161. Divide both sides by 14 to get the variable alone. This gets you 11.5. So the width is 11.5. Hope this helps

True [87]

Answer:

Step-by-step explanation:

Surface area is pretty synonymous with area.

How much paint is needed to paint the outside of a birdhouse?

Paint is measured in volume, so not surface area

How much wallpaper is needed to cover the walls of your room?

Since its just the walls its not total surface area, but surface area of the walls.

How much water will it take to fill a rectangular container?

water is measured in volume, especially when wanting to fill something.

How much topsoil can a gardener place in his wheelbarrow?

Wants to know how much topsoil is needed to FILL the wheelbarrow, filling is volume. So not surface area.

How much fabric is needed to make a pillowcase for a pillow?

Not asking to fill the pillowcase, just how much is needed for the thin, one layer thick case. So this is surface area.

Record for Boston Marathon's wheelchair division is 1 hour, 18 minutes, and 27 seconds.

aleksley [76]

1 hr 18 minutes and 27 seconds hmmm

there are 60 minutes in 1 hr, thus 18 minutes is 18/60 hrs or 0.3hr.

so 1hr 18min is 1.3 hrs

there are 60 seconds in 1 minute and 60 minutes in 1 hr, thus 60*60 seconds in 1hr, or 3600 seconds, so, 27 seconds is just 27/3600 hrs, or 0.0075 hrs.

so, 1.3 hr or 1.3000 hr for that matter plus 0.0075, is just 1.3075 hrs.

a)

so, they covered 26.2 miles in 1.3075 hrs, so the average speed is just 26.2/1.3075, or about 20.0382409177 miles/hr

b)

$\bf \begin{array}{ccll}
miles&hrs\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
26.2&1.3075\\
30&h
\end{array}\implies \cfrac{26.2}{30}=\cfrac{1.3075}{h}\implies h=\cfrac{1.3075\cdot 30}{26.2}$

Determine the slope of the line shown.

marin [14]

Pick 2 points off ur line...it is easier if u pick whole number points

(2,0) and (0,5)
slope formula = (y2 - y1) / (x2 - x1)
now label ur points
(2,0)...x1 = 2 and y1 = 0
(0,5)...x2 = 0 and y2 = 5
now sub and find the slope
slope(m) = (5 - 0) / (0 - 2) = -5/2 <====

Find the length of LA <br> Triangle proportionality

Answer:

Step-by-step explanation:

4 x __ = 12

the blank would be 3, once you did it on one side you have to do it on the other side too

5 x 3 = 15

Another way you can do it is by...

$\frac{4}{12}$ = $\frac{5}{x}$
