What is the exact value of the side length of a square with an area of 30 square units?

Answer:

d; 151 bracelets

Step-by-step explanation:

to find this out we must divide each number of beads by their matching color amounts

1012 / 5 is 202.4 or 202

998 / 6 is 164.6... or 164

1057 / 7 is 151

151 is the least number out of all of these and in this case you can only make 151 bracelets or else you would run out of white

Step-by-step explanation:

Consider the line y=x+1. Rotate this 90 degrees, and you get a line with a slope of -1, which obviously cannot be parallel.

Answer:

x = 0, y = -3/2

Step-by-step explanation:

Solve the following system:

{-2 y + x = 3 | (equation 1)

{-8 y + 14 x = 12 | (equation 2)

Swap equation 1 with equation 2:

{14 x - 8 y = 12 | (equation 1)

{x - 2 y = 3 | (equation 2)

Subtract 1/14 × (equation 1) from equation 2:

{14 x - 8 y = 12 | (equation 1)

{0 x - (10 y)/7 = 15/7 | (equation 2)

Divide equation 1 by 2:

{7 x - 4 y = 6 | (equation 1)

{0 x - (10 y)/7 = 15/7 | (equation 2)

Multiply equation 2 by 7/5:

{7 x - 4 y = 6 | (equation 1)

{0 x - 2 y = 3 | (equation 2)

Divide equation 2 by -2:

{7 x - 4 y = 6 | (equation 1)

v0 x+y = -3/2 | (equation 2)

Add 4 × (equation 2) to equation 1:

{7 x+0 y = 0 | (equation 1)

{0 x+y = -3/2 | (equation 2)

Divide equation 1 by 7:

{x+0 y = 0 | (equation 1)

{0 x+y = -3/2 | (equation 2)

Collect results:

Answer: x = 0, y = -3/2

Solution:

Note that:

Step-by-step explanation:

Let coordinate of M(x, y)

we know,

image of M(x,y)-------M'(-y,x)

From question

(-y,x)= (-5,-4)

or, -y = -5 and x= -4

3+8=11

Step-by-step explanation:

3×1=3

y=(1)+3

y=4

3(1)+2(4)=11

so then 3+8=11

Answer:

x=1 and y=4

Step-by-step explanation:

3x+2y=11...........(1)

y=x+3................(2)

Substituting the value of y in equation (1).

3x+2(x+3)=11

3x+2x+6=11

5x=11-6

5x=5

x=5/5=1

x=1

Now, again

Substituting the value of x in equation 2.

y=1+3=4

y=4

Therefore, x=1 and y=4.

Answer:

x = -2

y = 10

Step-by-step explanation:

(0.3 + 0.7) x + (0.4 - 0.8) y = 0.8 - 6.8

x - 0.4 y = -6 → x = 0.4 y - 6

0.3 ( 0.4 y - 6) + 0.4 y = 0.8 → 0.12y +0.4y - 1.8 = 0.8

→ 0.52 y = 2.6 → y = 2.6/0.52 = 10

x - 0.4(10) = -6 → x = -2

Step-by-step explanation:

0.3x + 0.4y = 0.8 /×2

0.7x - 0.8y = -6.8

1. 0.6x + 0.8y = 1.6

2. 0.7x - 0.8y = -6.8

1+2 : 1.3x + 0y = -5.2

1.3x = -5.2

x = -5.2÷1.3

x = -4

x -> 1 : 0.6 × -4 + 0.8y = 1.6

-2.4 + 0.8y = 1.6

0.8y = 4

y = 4÷0.8

y = 5

Answer:

Given: △ABC, m∠B=90° AB=12, BC=16, BK ⊥ AC . Find: AC and BK.

Given: △ABC, m∠B=90°

Find: AC and BK.

Short leg 90 degrees Long leg Hypotenuse

AB=12 90 BC=16 AC= ?

AK = ? 90 BK = ? AB=12

AC = SQRT (AB*AB + BC*BC) = 20 [right triangle; Pythagorean Theorem]

Similar triangles:[Note: In diagram, share two angles. Therefore share three angles]

BK / 16 = AB / AC

BK / 16 = 12 / 20

BK = (3/5)16

BK = 48/5

another answer let see this

AB^2+BC^2=AC^2

12^2+16^2=AC^2

144+256=AC^2

400=AC^2

20=AC

# be careful#

ΔABC and ΔBKC are similar triangles, the missing measures are:

If two triangles are similar, their corresponding sides are proportional to each other.

When a segment of a right triangle intersects the hypotenuse, the triangles formed are similar to each other.

Thus, using Pythagorean Theorem:

AC = √(AB² + BC²)

Substitute

AC = √(12² + 16²)

AC = 20 units.

Find BK:

ΔABC ~ ΔBKC (similar right triangles)

Thus:

AB/BK = AC/BC

Substitute

12/Bk = 20/16

Cross multiply

BK = (16 × 12)/20

BK = 9.6

Therefore, ΔABC and ΔBKC are similar triangles, the missing measures are:

AC = 20 units

BK = 9.6 units.

Answer:

4(2x+2)=8(2-3x)

First I am going to distribute the 4 and the 8 on the sides of the equation.

This gets me to

8x + 8 = 16 - 24x

then subtract 8x on both sides to get

8 = 16 - 16x

then subtract 16 on both sides to isolate the -16x

-8 = -16x

then divide by -16 on both sides, to make the x variable positive and isolate the variable even more.

Answer:

Area of bigger rug = 57.6ft squared

Width of bigger rug = 6ft

Step-by-step explanation:

Because the rugs are similar, we can do 9.6/8 = 1.2

1.2 is our scale factor (the amount we need to times or divide by to find other missing widths or lengths)

To find the area of the rug, we want to do width x length, however the bigger rug doesn't have a width. So, we have to calculate the width.

The width of the smaller rug is 5ft, and we know our scale factor is 1.2, so 5*1.2=6

Therefore, the with of the larger rug is 6ft.

Area = 6*9.6=57.6ft squared

Hope this helps!
