Raiding British convoys, he became the richest man in America. He personally signed 6,000 notes to pay off Washington's troops when the war ended.

Umnica [9.8K]

Answer:

Hence required paper for entire shape will be L[L+2(2H+H1)] Sq.cm

Step-by-step explanation:

Given:

A block with rectangular prism at bottom and square pyramid at top.

To Find:

Paper required to cover whole block

Solution:

We know that block consist of two different shapes as prism and pyramid.

So paper covering will be for surface.

hence we required surface area for rectangular prism and square pyramid.

(Refer the attachment)

Now only outer surface should be consider in order to cover the shape.

for square pyramid its length and breadth will be the same .

let L be length and B be breadth and h be height

<em>So total no.of faces will be 6 but on top there is prism placed so top surface will be neglected for the calculations</em>.

H<em>ence No.of faces will be 5.</em>

So total surface area for square pyramid will be

=L*W+2(L*H+W*H)

Here L=W as it is square pyramid

=L^2+4(L*H)

Now for the Prism surface it will have 4 triangles placed on with base as length of pyramid(as shown in fig) and height be H1

So Total area for Prism will be

=4( Area of triangles)

=4*1/2*base*height)

=2*base *height

=2*L*H1

So required Paper will be

Total surface area=Surface are of pyramid+ Area of 4 triangles.

=L^2+4(L*H)+2*L*H1

=L[L+2(2H+H1)].

Triangle ABC is located at A (−2, 2), B (−2, 4), and C (0, 0). The triangle is then transformed using the rule (x+3, y−2) to for

Dominik [7]

Answer:

A'(1, 0 ), B'(1, 2 ), C'(3, - 2)

Step-by-step explanation:

using the rule, add 3 to the x-coordinate and subtract 2 from the y- coordinate of the original points.

A' = (- 2 + 3, 2 - 2 ) = A'(1, 0 )

B' = (- 2 + 3, 4 - 2 ) = B'(1, 2 )

C' = (0 + 3, 0 - 2 ) = C'(3, - 2 )

Leave the answer as an improper fraction

Ghella [55]

Hey there!

ANSWER: $\frac{23}{20}$

EXPLANATION:

To find the answer to your question, you will need to add.

$\frac{3}{4}+\frac{2}{5}$

First, multiply the denominator.

$5*4=20$

So the denominator will be 20.

Now move on to the numerator. Multiply 5 by 3.

$5*3=15$

Now multiply 4 bu 2.

$4*2=8$

If you want to get the numerator, add what you got after multiply.

$15+8=23$

The numerator is 23. So now let's complete the fraction.

$\frac{23}{20}$

This is your answer!

Hope this helps!

What assumption have you made in answering part b

emmasim [6.3K]

You're assuming that this data set represents all of Mrs. Hassaan's pupils. Certain students could be missing from the histogram - for instance, there could be one or two students who missed the test, but for certain reasons will be taking a make-up exam. Their grade would not be recording in this data set, but they still contribute to the class size, and so would be unaccounted for here.
