Find the surface area of the square pyramid 8mm 6mm

bija089 [108]

Answer:

136 mm²

Step-by-step explanation:

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

$A=6^{2} +2(6)\sqrt{\frac{6^{2} }{4} } +8^{2}$

$A=36 +12\sqrt{\frac{36 }{4} } +64$

$A=36 +12\sqrt{9 } +64$

$A=36 +12(3)+64$

$A=36 +36+64$

A = 136

Among the eighth-graders in Michael's school, 70% have siblings. The eighth-grade class is 5/6 the size of the seventh-grade cla

nikklg [1K]

Answer:

d. 192

Step-by-step explanation:

OK so if 70% of students in 8th grade have siblings and 112 8th graders have siblings, then:

0.7(total 8th graders) = 112

total 8th graders = 112/0.7

total 8th graders = 160

And since the number of 8th graders is 5/6 the size of the 7th grade class:

5/6(7th grade class) = 160

5(7th grade class) = 960

7th grade class = 192.

The correct answer is D) 192.

Can anyone help please?

Answer:

2x+y=5.

Step-by-step explanation:

slope(m)=-2

passed through point (0,5)=(x1,y1)

then

the equation is

(y-y1)=m(x-x1)

or (y-5)=-2(x-0)

or (y-5)=-2x

or 2x+y=5 is the equation.
