What is the perimeter of the rectangle with the vertices shown below? A(4, 7), B(4, 15), C(9, 15), D(9,7)

Answers

Answer:

[tex]X=26[/tex]

Step-by-step explanation:

From the question we are told that:

Co_ordinates of rectangle:

[tex]A(4, 7),\\ B(4, 15),\\C(9, 15),\\D(9,7).[/tex]  

Generally the equation for rectangular Perimeter X is is mathematically given by

[tex]X=2(length+breath)\\X=2L+2B[/tex]

Generally the Length of the rectangle is mathematically given by

[tex]L=(y\ axis\ co-ordinate\ of\ C)-(y\ axis\ co-ordinate\ of\ D)\\or\\L=(y\ axis\ co-ordinate\ of\ B)-(y\ axis\ co-ordinate\ of\ A)[/tex]

Therefore

[tex]L=15-7\\L=8[/tex]

Generally the Breath of the rectangle is mathematically given by

[tex]B=(x\ axis\ co-ordinate\ of\ D)-(x\ axis\ co-ordinate\ of\ A)\\or\\B=(y\ axis\ co-ordinate\ of\ C)-(y\ axis\ co-ordinate\ of\ B)[/tex]

Therefore

[tex]B=9-4\\B=5[/tex]

Generally the rectangular Perimeter X is is mathematically given by

[tex]X=2(8)+2(5[/tex]

Find the perimeter of the pentagon MNPQR with vertices ​M(2​, 4​), ​N(5​, 8​), ​P(​8, 4​), ​Q(8​, 1​), and ​R(2​, 1​)

Answers

Answer:

The pentagon MNPQR has a perimeter of 22 units.

Step-by-step explanation:

Geometrically speaking, the perimeter of the pentagon is the sum of the lengths of each side, that is:

[tex]p = MN + NP + PQ + QR + RM[/tex] (1)

[tex]p = \sqrt{\overrightarrow{MN}\,\bullet \, \overrightarrow{MN}} + \sqrt{\overrightarrow{NP}\,\bullet \, \overrightarrow{NP}} + \sqrt{\overrightarrow{PQ}\,\bullet \, \overrightarrow{PQ}} + \sqrt{\overrightarrow{QR}\,\bullet \, \overrightarrow{QR}} + \sqrt{\overrightarrow{RM}\,\bullet \, \overrightarrow{RM}}[/tex] (1b)

If we know that [tex]M(x,y) = (2,4)[/tex], [tex]N(x,y) = (5,8)[/tex], [tex]P(x,y) = (8,4)[/tex], [tex]Q(x,y) = (8,1)[/tex] and [tex]R(x,y) = (2,1)[/tex], then the perimeter of the pentagon MNPQR is:

[tex]p =\sqrt{(5-2)^{2}+(8-4)^{2}} + \sqrt{(8-5)^{2}+(4-8)^{2}}+\sqrt{(8-8)^{2}+(1-4)^{2}}+\sqrt{(2-8)^{2}+(1-1)^{2}}+\sqrt{(2-2)^{2}+(4-1)^{2}}[/tex][tex]p = \sqrt{3^{2}+4^{2}} + \sqrt{3^{2}+(-4)^{2}}+\sqrt{0^{2}+(-3)^{2}}+\sqrt{(-6)^{2}+0^{2}}+\sqrt{0^{2}+3^{2}}[/tex]

[tex]p = 22[/tex]

The pentagon MNPQR has a perimeter of 22 units.

answer

The pentagon MNPQR has a perimeter of 22 units.

Geometrically speaking, the perimeter of the pentagon is the sum of the lengths of each side, that is:

p = MN + NP + PQ + QR + RMp=MN+NP+PQ+QR+RM (1)

p = \sqrt{\overrightarrow{MN}\,\bullet \, \overrightarrow{MN}} + \sqrt{\overrightarrow{NP}\,\bullet \, \overrightarrow{NP}} + \sqrt{\overrightarrow{PQ}\,\bullet \, \overrightarrow{PQ}} + \sqrt{\overrightarrow{QR}\,\bullet \, \overrightarrow{QR}} + \sqrt{\overrightarrow{RM}\,\bullet \, \overrightarrow{RM}}p=

The talk-time battery life of a group of cell phone is normally distributed with a mean of 5 hours and a standard deviation of 15 minutes. A) What percent of the phones have a battery life of at least 4 hours and 45 minutes?

Answers

The correct answer is 84%

The phone battery lasts at least 4 hours and 45 minutes is 84%.

What is normal distribution of data?

A normal distribution is a probability distribution that is perfectly symmetrical around its mean (center), showing that data near the mean are more frequent in occurrence than data far from the mean. In graph form, normal distribution will appear as a bell curve.

For the given situation,

The normally distribution has a mean of 5 hours and a standard deviation of 15 minutes.

50% of the normal distribution lies to the right of the mean. So, the battery will last longer than 5 hours.

The interval from 4 hours and 45 minutes and 5 hours represents one standard deviation to the left of the mean.

So, about 34% of time, the battery will last between 4 hours and 45 minutes and 5 hours.

Thus, the probability that the battery lasts at least 4 hours and 45 minutes,

⇒ [tex]50+34[/tex]

⇒ [tex]84[/tex]

Hence we can conclude that the phone battery lasts at least 4 hours and 45 minutes is 84%.

Choose the correct future tense form of the verb in parentheses.

Ellos (saber) la verdad.

sabré
sabrás
sabremos
sabrán
.

Answers

Answer:

The correct future tense would be sabrán, which basically means they will know in English.

Step-by-step explanation:

Since the question states "Ellos" (they) as in a group of people, sabrán would be the right one.

These words (in order) basically roughly mean

I will know

You will know

We will know

THEY will know

Answer:

D. sabrán

Step-by-step explanation:

The form of the verb, saber, has to match the form of the pronoun that is doing the action. "Ellos" is doing the action, and ellos means "they". The "they" form of a verb ends with an "en" or "an". So your best answer is sabrán.

what is the greatest common factor of 49x^2-21

Answers

Answer:

7x

Step-by-step explanation:

First find the common factors of the numbers: 49, 21.

That would be 1 and 7.

The GCF is 7 b/c it is greater than 1.

Find the common factors of x and x^2.

That is x times x

The factor for  x ^1  is  x  itself.

The common factor for the both of them is x.

The GCF is then x.

The multiply the both of the GCFs (x.7) and you now have 7x.

So the GCF is 7x.

The greatest common factor of [tex]49\cdot x^{2}-21[/tex] is 7.

In this question, the greatest common factor of [tex]49\cdot x^{2}-21[/tex] is the greatest multiple applied on each term of the polynomial. First we notice that greatest common factor may be entirely constant. Then, we proceed to calculate each constant by factor decomposition:

[tex]49 = 7^{2}[/tex], [tex]21 = 3\times 7[/tex]

Hence, we conclude that greatest common factor of [tex]49\cdot x^{2}-21[/tex] is 7.

Boubacar went to the store to buy some walnuts. The price per pound of the walnuts
is $6.50 per pound and he has a coupon for $3.75 off the final amount. With the
coupon, how much would Boubacar have to pay to buy 4 pounds of walnuts? Also,
write an expression for the cost to buy p pounds of walnuts, assuming at least one pound is purchased.

Answers

Answer:

Step-by-step explanation:

Price per pound of the walnuts = $ 6.50

Price of 4 pounds of the walnuts = 4 *6.50 = $ 26

Amount needs to be paid = Price of 4 pounds of walnut - coupon amount

             = 26 - 3.75

              = $ 22.25

Expression:

Cost to buy p pounds of walnuts = p * 6.50 = 6.5p

Cost to buy p pounds of walnuts, assuming at least one pound is purchased =  6.50 + 6.5p

-4(m + 18) = 8 answer

Answers

Answer:

m = -20

Step-by-step explanation:

first distribute:

-4(m + 18) = 8

-4m - 72 = 8

Now add 72 to both sides to get m by itself

-4m = 80

and divide by -4 on both sides

m = -20

Hope this helped! :)

Answer: m = -20

Step-by-step explanation:

−4(m + 18) = 8

Step 1: Simplify both sides of the equation.

−4(m + 18) = 8

(−4)(m) + (−4)(18) = 8 (Distribute)

−4m + −72 = 8

−4m − 72 = 8

Step 2: Add 72 to both sides.

−4m − 72 + 72 = 8 + 72

−4m = 80

Step 3: Divide both sides by -4.

−4m / − 4 = 80 / −4

m = −20

40      48

Answer:

? = 35

Step-by-step explanation:

The lengths of corresponding sides of similar polygons are in the same ratio.

The sides measuring 48 and 40 are corresponding sides.

The ratio of their lengths is 48/40.

The sides measuring 42 and ? are also corresponding, so they are in the same ratio.

That means we can set up a proportion to solve for the side with length ?.

48/40 = 42/?

Simplify the fraction on the left side.

6/5 = 42/?

Cross multiply.

6 * ? = 5 * 42

Divide both sides by 6.

? = 5 * 7

? = 35
