Answer:

864 feathers

Step-by-step explanation:

Feather/inch² = 72 feathers/inches²

Area (inches²) = 3 × 4 = 12 inches²

Amount of feather on 12 inches² area will be ;

72 feathers/inches² × 12 inches² = 864 feathers

Izzie recently took a math test where each correct answer (a) on the main part of the test was worth 8.3 points. She also correc
Temka [501]

Answer:

12 correct answers

Step-by-step explanation:

Since in the main part she scores 8.3 points for each question she answers correctly, we can assume that the number of questions she answers correctly=a

Therefor, the total number of points she achieved in the math test in the main part alone can be expressed as:

Total score(main part)=8.3×a=8.3a points

She also solved a bonus question worth=11 points

Consider expression 1 below

The total score in the whole test=Total score in the main part+Bonus points, where;

Total score in the whole test=110.6 points

Total score in the main part=8.3a points

Bonus points=11 points

Substituting the values in expression 1:

8.3a+11=110.6

8.3a=110.6-11

8.3a/8.3=99.6/8.3

a=12

Number of correct answers in the main part=a=12

i have 60+8x=108 x=6 but for the other equation i dont know how to get rid of the 3x to solve for the y.
LUCKY_DIMON [66]
Angle a is congurent to angle e, so 60+8x=108
same with c and g.
so 8y-3x=62
just plug in x for there (6)
so 8y-24=62
then 8y=88
y=11

Find the surface area and round to the nearest tenth.
mart [117]
If you notice the tickmarks, that means all slanted sides are of length 2.5

now, a triangular prism, is just two triangles and three rectangles stacked up to each other, check the picture below, like so.  So to get the area of it, simply get the area of the rectangles and the triangles.

now, notice, the triangles have a base of 4 and an altitude/height of 1.5.

the rectangles on the left and right sides are just 2.5 x 6 each.

and the rectangle at the base of the prism, is a 4 x 6.

thus, the area of the triangular prism is just

\bf 2\left( \frac{1}{2}\cdot 4\cdot 1.5  \right)+2(2.5\cdot 6)+(4\cdot 6)\implies 6+30+24\implies \boxed{60}

What is the surface area of this triangular pyramid?<br> ___square inches
IrinaVladis [17]

Answer:

Surface area = 10.7 in.²

Step-by-step explanation:

Surface Area of triangular pyramid = BA + P*L

Base Area (BA) = ½*nh

b = 2 in.

h = 1.7 in.

BA = ½*2*1.7 = 1.7 in.²

Perimeter (P) = 2 + 2 + 2 = 6 in.

Slant height (L) = 3 in.

Plug in the values

Surface Area = 1.7 + ½*6*3

Surface area = 10.7 in.²
