Answer:

This shall be you answer2 points and y = questions with 4 points;

We solve the equation: x + y = 40 and 2x + 4y = 100;

Then, x = 40 - y;

2( 40 - y ) + 4y = 100;

80 - 2y + 4y = 100;

80 + 2y = 100;

2y = 20;

y = 10;

x = 40 - 10;

x = 30;

Step-by-step explanation:

Let x = questions with 2 points and y = questions with 4 points;
We solve the equation: x + y = 40 and 2x + 4y = 100;
Then, x = 40 - y;
2( 40 - y ) + 4y = 100;
80 - 2y + 4y = 100;
80 + 2y = 100;
2y = 20;
y = 10;
x = 40 - 10;
x = 30;

<span>1cm = 10mm
1 inch = 2.54 cm
1ft = 12 inch
(0.35 mm / day) * (1 cm / 10 mm) * (1 in / 2.54 cm) * (1 ft / 12 in) =

Plot triangle ABC on graph paper with points A(2,2). B(-2, -2) and C(8, -2).
bonufazy [111]

9514 1404 393

Answer:

  a) The new triangle is a reflection of the original across the origin. All angles, segment lengths, and line slopes have been preserved: the transformed triangle is congruent with the original.

  b) The new triangle is a reflection of the original across the origin and a dilation by a factor of 2. Angles have been preserved: the transformed triangle is similar to the original. The transformation is NOT rigid.

Step-by-step explanation:

1. The transformed triangle is blue in the attachment. It is congruent with the original. The transformation is "rigid," a reflection across the origin. All angles and lengths have been preserved, as well as line slopes.

__

2. The transformed triangle is orange in the attachment. It is similar to the original, in that angles have been preserved and lengths are proportional. It is a reflection across the origin and a dilation by a factor of 2. Line slopes have also been preserved. A dilation is NOT a "rigid" transformation.

Likurg_2 [28]

There will be only 6  cubes with only one side painted red.

Cube : A cube is a 3D shape having 6 equal square sides. it has 6 faces , 8 vertices and 12 edges.

According to the question

A 3 cm cube is divided into one centimeter cube.

Every face will have 9 cube each and from that 9 cube there will be only one 1 cube that will have one side painted red.

Since there are 6 faces,

cubes painted one side red = 6x1=6.

Therefore , There will be only 6  cubes with only one side painted red.
