What is the perimeter of the trapezoid below?

And can someone give the process of how it's solved? I kind of forgot how to solve it...

Answer:

No they are not equivalent

Step-by-step explanation:

The given expressions are r + 4(2 + r) – 12, and  8 + 2r – 6

Let us first put r= 2 in the above expression

2+4(2+2)-12= 6

and 8+2(2)-6 = 6

Now let us put r=5 in the above two expressions

5+4(2+5)-12 = 21

similarly, 8+2(5)-6 = 12

Clearly, the two expressions are not equivalent when we put r=2 and r=5 as the values coming are different.

Answer:

the first expression is 6.

the second expression is 12.

they are NOT equivalent.

5 odd numberis there 31,33,35,37,39

Five odd numbers are greater than 30 and less than 40 .

What is odd number?

Odd numbers are those that cannot be evenly divided by two. It cannot be evenly split into two different integers. An odd number will leave a reminder when divided by two. 1, 3, 5, 7 are example of odd numbers.

The odd number between 30 and 40 are 31,33,35,37,39.

Therefore, total number of odd numbers which are greater than 30 and less than 40 are 5.

12,800 naira

Step-by-step explanation:

length of the wire is equal to the perimeter of a square

perimeter of a square = 4 x length

4 x 3.2 = 12.8 inches

cost of the square = length of the wire x 50

12,8 x 50 = 640

20 x 640 = 12800

Answer:

Option (3)

Step-by-step explanation:

Given expression is,

[tex]\frac{2^3\times 125^\frac{2}{3}\times 81^\frac{3}{4}}{8^\frac{1}{3}\times 9\times 5^2}[/tex]

To solve the given expression we will apply the law of exponents,

[tex]\frac{2^3\times 125^\frac{2}{3}\times 81^\frac{3}{4}}{8^\frac{1}{3}\times 9\times 5^2}=\frac{2^3\times (5^3)^\frac{2}{3}\times (3^4)^\frac{3}{4}}{(2^3)^\frac{1}{3}\times (3^2)\times 5^2}[/tex]

                    [tex]=\frac{2^3\times (5^{3\times \frac{2}{3}})\times (3^{4\times \frac{3}{4}})}{(2^{3\times \frac{1}{3}})\times (3^2)\times 5^2}[/tex]

                    [tex]=\frac{2^3\times 5^2\times 3^3}{2\times 3^2\times 5^2}[/tex]

                    [tex]=\frac{2^3}{2}\times (\frac{5^2}{5^2})\times (\frac{3^3}{3^2})[/tex]

                    [tex]=2^{3-1}\times (1)\times 3^{3-2}[/tex]

                    [tex]=2^2\times 1\times 3[/tex]

                    [tex]=12[/tex]

Therefore, Option (3) will be the correct option.

Using the intersecting chord theorem you multiply the two lengths of one line together to equal the multiplication of the two dimensions on the second line.

The answer would be 15(4) = 5x

Answer:

Let the 1st paycheck be x (integer).

Mrs. Rodger got a weekly raise of $ 145.

So after completing the 1st week she will get $ (x+145).

Similarly after completing the 2nd week she will get $ (x + 145) + $ 145.

= $ (x + 145 + 145)

= $ (x + 290)

So in this way end of every week her salary will increase by $ 145.

Answer:

∠ 1 = 130°, ∠ 2 = 50°

Step-by-step explanation:

∠ 1 and 130° are alternate angles and congruent, so

∠ 1 = 130°

∠ 2 and 130° are same- side interior angles and are supplementary, so

∠ 2 + 130° = 180° ( subtract 130° from both sides )

∠ 2 = 50°

Answer: it is 130 and 50

Step-by-step explanation: Honestly, they already gave one angle so it is a  HUGE giveaway. 180-130 is 50, so the answers are 130 and 50.

Answer:

Step-by-step explanation:

Usually you do it by factoring into primes. But this choice of numbers has no common primes, so all three make up the LCM

7 * 10 * 3

210 = LCM

LCM of 4 10 and 12

4: 2 * 2

10: 2 * 5

12: 2*2*3

LCM: 2 * 2 * 3 * 5 = 60

If you don't find the LCM then the answer would be 480

Answer:

210

Step-by-step explanation:

When finding the LCM(least common multiple) you need to factor each number into the product of prime number also called finding the prime factorization. Both 7 and 3 are prime, so they do not need to be factored further. However, 10 can be factored into 5 x 2.

3 - 3

7 - 7

10 - 5 x 2

By looking at the factors above, you notice none of them are the same, so none of the numbers share factors. This means you can just multiply all the factors to get the LCM:

3 x 7 x 5 x 2

Answer:linear

Step-by-step explanation:

it is a straight line

The best-fitting regression model for the scatterplot is linear. Thus, the correct answer is an option (A).

As per the given figure, the data points on a scatterplot, with the dependent variable (y-axis) plotted against the independent variable (x-axis).

Looking at the general pattern of the data points on the scatterplot.

Here, they follow a roughly linear trend.

This means that the data points roughly form a straight line or a curve that looks like a straight line.

Thus, the best-fitting regression model for the scatterplot is linear.

Hence, the correct answer is option (A).

The right solution is:

(a) $1,940

(b) $2,813

Step-by-step explanation:

Given:

Invoice amount

= $8,400

Discount 1

= 33.33%

Discount 2

= 12.5%

So,

The net payable amount will be:

= [tex]8400\times [1 - \frac{100}{300} ]\times [1 - \frac{12.5}{100} ][/tex]

= [tex]8400\times \frac{2}{3}\times 0.875[/tex]

= [tex]4900[/tex] ($)

Now,

(a)

Amount paid will be:

= [tex]2000\times 0.97[/tex]

= [tex]1940[/tex] ($)

Balance still to be paid will be:

= [tex]4900-2000[/tex]

= [tex]2900[/tex] ($)

(b)

Amount paid will be:

= [tex](4900- 2000)\times 0.97[/tex]

= [tex]2900\times 0.97[/tex]

= [tex]2813[/tex] ($)

Balance still to be paid will be:

= [tex]2000[/tex] ($)

Thus the above solution is the appropriate one.

Answer:

Linear

Step-by-step explanation:

The rule is that linear equations must have exponents of 1 (a sloped line) or 0 A verticle or horizontal line). This function can be simplified to

y = 3x - 12 + 5 = 3x - 7 which is the standard form of a linear equation

y - mx + b where m is the slope and m is the y intercept.
