=2l + 2w

Perimeter of rectangle

21 + 2w = 16

as you know 21 is 2l,

one length

2l = 21

l =21/2

l = 10.5

Answer

10.5 inches

Answer:

[tex]l=8-w[/tex]

Step-by-step explanation:

We have been given that the perimeter of a rectangle is 16 inches. The equation that represents the perimeter of the rectangle is [tex]2l+2w=16[/tex], where [tex]l[/tex] represents the length of the rectangle and w represents the width of the rectangle.

Let us solve for [tex]l[/tex].

Factor out 2:

[tex]2(l+w)=16[/tex]

Divide both sides by 2:

[tex]\frac{2(l+w)}{2}=\frac{16}{2}[/tex]

[tex]l+w=8[/tex]

Subtract w from both sides:

[tex]l+w-w=8-w[/tex]

[tex]l=8-w[/tex]

Therefore, the expression [tex]8-w[/tex] represents length of rectangle.

Answer:

[tex]y + 1 = -\frac{5}{6}(x-6)[/tex]

or

[tex]y = -\frac{5}{6}x +4[/tex]

Step-by-step explanation:

Parallel lines are lines which have the same slope. To write the equation of the line parallel, find the slope of the equation 5x + 6y = 6 through conversion into slope intercept form.

5x + 6y = 6 becomes y = -5/6x + 1. The slope is -5/6.

Substitute\ m =-5/6 and the point (6,-1) into the slope intercept form.

[tex]y-y_1=m(x-x_1)\\y --1 = -\frac{5}{6}(x - 6)\\y + 1 = -\frac{5}{6}(x-6)[/tex]

Convert the equation to slope intercept form by applying the distributive property.

[tex]y + 1 = -\frac{5}{6}(x-6)\\y + 1 = -\frac{5}{6}x +5\\y = -\frac{5}{6}x +5-1\\y = -\frac{5}{6}x +4[/tex]

Answer:

53 add the 2 and you get 8

Step-by-step explanation:flip them 35 + 18 =53

Answer:

53

Step-by-step explanation:

 Let x = the first digit

and y = the second digit. Then,

    xy = the number

We have two conditions:

(1) x + y = 8

(2) 10y + x = 10x + y - 18

Simplify (2)                     10y + x - 10x - y = -18

                                              (3) 9y - 9x  = -18

Multiply Equation (1) by 9     (4) 9x + 9y =  72

Add Equations (3) and (4)                18y =  54

Divide each side by 18         (5)           y =    3

Substitute (5) into (1)                       x + 3 =   8

Subtract 3 from each side                   x =   5

x = 5 and y = 3

The number is 53.

Check:

(1) 5 + 3 = 8     (2) 10×3 + 5 = 10×5 + 3 - 18

         8 = 8             30  + 5 =   50  + 3 - 18

                                      35 =       53    - 18

                                      35 =            35

Answer:

174 75/142

B

Step-by-step explanation:

Formula

1 coin = Total Mass / number of coins

Givens

Total mass 24783 Ounces (That's awfully heavy. You sure you don't mean grams?)

142 coins

Solution

1 coin = 24783 / 142

1 coin = 174.528169

This is multiple choice so you only have to try one thing. What is 75/142? It turns out that the result is 75/142

75/142 = 0.528169

Another way to do it is to figure out what 174 in whole numbers would weigh:

174 * 142 = 24708

What number is left over? 24783 - 24708 = 75

So the fractional part is 75/142

Step-by-step explanation:

AMSWER is A .180

Answer:

64

Step-by-step explanation:

To find the area of the figure, split it into two shapes - a trapezoid and a rectangle.

The area of the trapezoid is found using A = 1/2 (a+b)h. Substitute a = 6, b = 4 and h = 8.

A = 1/2(6+4)(8) = 1/2(10)(8) = 40

The area of a rectangle is found using A = b*h. Substitute b = 6 and h = 4.

A = 6*4 = 24

Together the area adds to 40 + 24 = 64

Answer:

Step-by-step explanation:

Lets c = chord inside circle

3(3 + c) = 6^2

9 + 3c = 36

3c = 27

c = 9

x = 3 + 9

x = 12

Answer:

The answer is x=12

Step-by-step explanation:

In order to determine the "x" value, we have to know about the tangent to a circle.

The line that joins two infinitely close points from a point on the circle is a Tangent. It means, the lines that intersect the circles exactly in one single point are tangents.

I have attached an image that shows a tangent to a circle. Also there is a formula that relates the segments of the circle.

According to the same notation of the image:

[tex]PS^2=PQ*PR[/tex]

In this case:

[tex]PS=6\\PQ=3\\PR=x\\6^2=3*x\\x=\frac{36}{3}=12[/tex]

Finally the answer is x=12

Answer:

It is 12. 12 fossils were found in Wyoming.

Step-by-step explanation:

The area of the circular stained-glass window is 50.24 square yards.

To find the area of the circular stained-glass window, we need to use the formula for the area of a circle: A = πr². Since we know the circumference of the window is 25.12 yards, we can use the formula C = 2πr to solve for the radius. Dividing both sides of the equation by 2π, we get r = C/(2π) = 25.12/(2 × 3.14) = 3.9996 yards. Now we can substitute this value of r into the formula for the area to find the window's area: A = 3.14 × (3.9996)² = 50.24 square yards.

Answer:

vertical

Step-by-step explanation:

you can flip it and it be the same.

The type of line of symmetry that the figure has is none.

It is a line, when drawn through a figure, the figure can be folded along the line of symmetry and both sides would coincide.

The given figure is a parallelogram.

It does not have a vertical line of symmetry, because when we fold the figure, both sides of the figure won't coincide.

It does not have a horizontal line of symmetry, because when we fold the figure, both sides of the figure won't coincide.

It does not have a diagonal line of symmetry, because when we fold the figure, both sides of the figure won't coincide.

Therefore, the given figure has no lines of symmetry. The correct answer is option D.

.62, 7/9,10/9 the easyiest way to do this is by putting it in decimal form or just look 7/9 is more then .62 and 10/9 is a mixed number

Answer:

0.62, 7/9, 10/9

Step-by-step explanation:

First you want to convert the fractions to decimals.

10/9 = 1.110

7/9 = 0.778

0.62 = 0.62

then you order them from least to greatest.

0.62, 7/9, 10/9

Answer:   c) -1372

Step-by-step explanation:

[tex]\sqrt[3]{2x} +6=-8\\\\\sqrt[3]{2x} =-14\\\\(\sqrt[3]{2x})^3 =(-14)^3\\\\2x=-2744\\\\\boxed{x=-1372}[/tex]

First divide 1/4=0.25 and then multiply 0.25 bu 100% so the result is 25%

For the dumonitor remember that 4 x 25 is 100.

Our Multiple is 100.

So that means we need to multiply 1 and 4 by 25.

1×25 = 25 so our top number is 25.

4x25 is 100 which would be our bottom number.

We end up with 25/100.

That as a percent would be [tex]\fbox{25percent}[/tex] / 25%

Answer:

1/16

Step-by-step explanation:

1/2 divided by 8= 0.0625

There is not much that can be done to figure out how to write 0.0625 as a fraction, except to literally use what the decimal portion of your number, the .0625, means.

Since there are 4 digits in 0625, the very last digit is the "10000th" decimal place.

So we can just say that .0625 is the same as 0625/10000.

The fraction is not reduced to lowest terms. We can reduce this fraction to lowest

terms by dividing both the numerator and denominator by 625.

Why divide by 625? 625 is the Greatest Common Divisor (GCD)

or Greatest Common Factor (GCF) of the numbers 625 and 10000.

So, this fraction reduced to lowest terms is

So your final answer is:  1/16
