Someone Please Help Me On This I'm Unsure If My Answer Is Correct

Answer 1

Answer:

A. length = 23 cm; width = 5 cm

Step-by-step explanation:

So if 4 times the width would be [tex]4w[/tex] and 3 more than would be [tex] + 3[/tex], the equation would be [tex]l = 4w + 3[/tex]. If the perimeter is 56, then the new equation, [tex]2(4w + 3) + 2(w) = 56[/tex] can be formed. This simplifies to [tex]8w + 6 + 2w = 56[/tex], then to [tex]10w + 6 = 56[/tex], then to [tex]10w = 50[/tex], and finally, [tex]w = 5[/tex]. So the width is 5, and now plug it into the first equation.

[tex]l = 4(5) + 3[/tex], becomes [tex]l = 20 + 3[/tex], becomes [tex]l = 23[/tex].

So the dimensions are: length = 23 cm, width = 5 cm.

*And just to be sure, [tex]2(23 + 5) = 2(28) = 56[/tex] which is correct.

You add 376 and 266 together then you get 642

In this case the nearest ten is 2

If we round the 2 (which would go down) it would be 640

Answers

Answer:

(4,-6)

Step-by-step explanation:

The y axis is the North and South direction, or up and down on the graph. Starting at point (-2,1), where y = 1, to move up add, or to move south subtract. To move 7 blocks south 1 - 7 = -6

The x axis is East and West or to the right or left respectively. To move East / right add, to move West / left subtract. In the point (-2,1) x = - 2 so to move 6 blocks east add. -2 + 6 = 4

If angle e and angle f are complementary if measure of angle e = 9x+22 and measure of angle f = 2x+24 fine measure of angle f

Answers

Answer: 32°

Step-by-step explanation:

Complementary angles are the ankea that are equal to 90° when we add them together. This will then be:

9x+22 + 2x+24 = 90

11x + 46 = 90

11x = 90 - 46

11x = 44

x = 4

Angle F = 2x + 24

= 2(4) + 24

= 8 + 24

= 32°

Find the surface area of the cuboid shown below

Answers

Answer:

Surface area of cuboid = 352 cm

Step-by-step explanation:

Given that:

Height of cuboid = 8 cm

Length of cuboid = 12 cm

Width of cuboid = 4 cm

Surface area = 2lw + 2lh + 2hw

Putting all the values;

Surface area = 2*12*4 + 2*12*8 + 2*8*4

Surface area = 96 + 192 + 64

Surface area = 352 cm

Hence,

Surface area of cuboid = 352 cm
