Find the SLANT HEIGHT of the pyramid, then calculate its SURFACE AREA.

Vedmedyk [2.9K]

Answer:

13 cm

Step-by-step explanation:

slant height = $\sqrt{12^2 +\frac{10^2}{4} }$

= $\sqrt{144 + \frac{100}{4} }$

= $\sqrt{144 + 25}$

= $\sqrt{169}$

=13 cm

a=10 cm

l =

surface area = $a^{2} + 2a \sqrt{\frac{a^{2} }{4} +h^{2} }$

= $10^{2} +2*10 \sqrt{\frac{10^{2} }{4} +12^{2} } \\100 + 20 \sqrt{\frac{100}{4} + 144} \\100 + 20\sqrt{25 + 144} \\100 + 20 \sqrt{169} \\100 + 20*13\\100 + 260\\360 cm^2$

You are going to use an incline plane to lift a heavy object to the top of a shelving unit with a height of 6 ft. The base of th

jeka94

Answer:

11.66 ft

Step-by-step explanation:

-This a Pythagorean Theorem problem

-Let X be the length of the incline plane.

#X can be found using the Pythagorean theorem identity:

$b^2+h^2=H^2\\\\6^2+10^2=X^2\\\\X^2=136\\\\X=\sqrt{136}\\\\=11.66\ ft$

Hence, the length of the incline is 11.66 ft

Which is the best estimate of 162% of 79?

LUCKY_DIMON [66]

First, you round your numbers:

162% to 160

and

79 to 80

I would divide 160 (%) by 80 which, obviously, is 2

My best estimate would be 2

Hope this helps!
