A room has a length of 12.62 ft and a width of 10.2 ft. Find the perimeter of the room with the correct number of significant digits.

8x+4= 20

move +4 to the other side

sign changes from +4 to -4

8x+4-4= 20-4

8x= 20-4

8x= 16

divide both sides by 8 to get x by itself

8x/8= 16/8

Cross out 8 and 8, divide by 8 and then becomes 1*1*x= x

x= 16/8

Answer: D. x = 2

In order to get the answer to this question you will have to solve the equation before you can get the answer.

[tex]8x+4=20[/tex]

[tex]-4-4[/tex]

[tex]20-4=16[/tex]

[tex]8x=16[/tex]

[tex]\div8\div8[/tex]

[tex]16\div8=2[/tex]

[tex]x=2[/tex]

Therefore your answer is option D "x = 2."

14000:21000

Step-by-step explanation:

2:3 = 2x + 3x

2x + 3x = 35,000

5x = 35,000

x = 35,000/5

x = 7000

2x = 7000 * 2

    = 14000

3x = 7000 * 3

Answer:

The measure of angle L is 40°

Step-by-step explanation:

we know that

In a parallelogram the opposite angles are congruent and the opposite sides are congruent and parallel

see the attached figure to better understand the problem

so

In this problem

∠L≅∠N

∠M≅∠O

we have

∠L=(3x-20)°

∠N=(2x)°

so

equate the angles and solve for x

[tex](3x-20)\°=(2x)\°[/tex]

[tex]3x-2x=20[/tex]

[tex]x=20[/tex]

Find the measure of angle L

[tex]L=(2x)\°[/tex]

substitute the value of x

[tex]L=(2(20))=40\°[/tex]

Answer:

P(0,1)

Step-by-step explanation:

The vertices of pentagon PQRST are P(0, 1), Q(2, 2), R(5, 3), S(4, 0), and T(1,−1).

If a figure reflected across y-axis, then the relation between preimage and  image is

[tex](x,y)\rightarrow (-x,y)[/tex]

If the pentagon PQRST reflected over the y-axis, then vertices of image are

[tex]P(0,1)\rightarrow P'(0,1)=P[/tex]

[tex]Q(2,2)\rightarrow Q'(-2,2)[/tex]

[tex]R(5,3)\rightarrow R'(-5,3)[/tex]

[tex]S(4,0)\rightarrow S'(-4,0)[/tex]

[tex]T(1,-1)\rightarrow T'(-1,-1)[/tex]

Therefore, only vertex P will not change its coordinates after reflection.

The fifth root of x can be expressed as a power of 1/5 this way:

x^(1/5).

Now raise [x^(1/5)] to the 9th power.

[x^(1/5)]^(9)

Multiply the powers to complete the problem.

x^(9/5)

Answer: Choice B.

The expression 'fifth root of x to the power of 9' can be rewritten as 'x to the 9/5 power' in terms of rational exponents, this is option b.

The correct rewrite of the expression, 'fifth root of x to the power of 9', utilizing rational exponents instead of a radical approach, is expressed as x to the 9/5 power. When translating a radical to a rational exponent, the index of the root becomes the denominator and the power of the term inside the root becomes the numerator.

So, fifth root of x to the power of 9 translates to x to the power of 9/5, which corresponds to option b.

Final answer:

The expression 80 + (-22 4/15) is solved by converting the mixed number to an improper fraction, aligning the fractions by the same denominator, and then adding them to get 58 4/15 as the result.

Explanation:

To solve the expression 80 + (-22 4/15), follow these steps:

First, convert the mixed number -22 4/15 into an improper fraction. To do this, multiply the whole number by the denominator and add the numerator: (-22 × 15) + 4 = -330 + 4 = -326, so the mixed number becomes -326/15.

Next, since 80 is a whole number, we can convert it into a fraction with the same denominator of 15 to make it easier to add to -326/15. To do that, multiply 80 by 15/15, which is the equivalent of 1, to get the fraction 1200/15.

Now, add the two fractions: 1200/15 + (-326/15) = (1200 - 326)/15 = 874/15.

This fraction can be simplified back into a mixed number by dividing the numerator by the denominator: 874 ÷ 15 = 58 with a remainder of 4, so the mixed number is 58 4/15.

Therefore, the solution to the expression 80 + (-22 4/15) is 58 4/15.

Answer:

5

Step-by-step explanation:

2(3x + 6) = 42

(3x + 6) = 42/2

(3x + 6) = 21

3x + 6  = 21

3x  =  21 - 6

3x  =  15

x = 1/3

x = 5

Answer:

The answer would be x=5

Step-by-step explanation:

2(3x+6)=42

so what you're gonna do is use the distributive property, so you would multiply 2 and 3x, and 2 and 6. so then you would have:

6x+12=42

Now you want to get rid of the twelve so you can solve for x. So you are going to subtract 12 from 12 and 42. So now you have:

6x=30

Next you're going to divide 6x and 30 by 6. So you would have x=5

Answer:

for tomas 19.100-6.15=$13.85dollars

so tomas's shirt cost $13.85

for kyle 9.100-1.06=$8.94

13.85-8.94=4.91

so tomas's shirt $4.91more than Kyle's shirt

Answer:

Tomas's shirt costs $4.91 more than Kyle's shirt.

Step-by-step explanation:

It is given that Tomas gave the cashier a $20 bill and received $6.15 in change. So, the cost of Tomas's shirt is the difference between the amount he gave and he received in change.

Cost of Tomas's shirt = $20 - $6.15 = $13.85

Kyle gave the cashier a $10 bill and received $1.06 in change. So,

Cost of Kyle's shirt = $10 - $1.06 = $8.94

The cost of Tomas's shirt is $13.85 and the cost of Kyle's shirt is $8.94.

Cost of Tomas's shirt is more that the cost of Kyle's shirt.

$13.85- $8.94=$4.91

Therefore, Tomas's shirt costs $4.91 more than Kyle's shirt.

Answer:

The correct option is the last one (0,84 grams, because (5.04 × 1.67) × (10^23 x 10^-24) = 8.4168 x 10^-1))

Step-by-step explanation:

The first step is to think that you have to multiply the number of atoms for the weight of each atom.

When you work with scientific notation, you should solve the operation for numbers and for the ten base. In this case you solve 5.04 x 1.67 and then the product of the ten bases. For this product you have to sum the exponents of the ten base 23 + (-24) = -1.

Summarizing.... 5.04 x 10^23 x 1.67 x 10^-24 = (5.04 x 1.67) x (10^23x10^-24)  ⇒ 5.04 x 10^23 x 1.67 x 10^-24 = 8.4168 x 10^-1

⇒ 5.04 x 10^23 x 1.67 x 10^-24 = 0,84168.

1. Volume of a cylinder is πr^2h

Area of the base would be πr^2

Volume would be the height x the area of the base:

Volume = 5 x 20 = 100 cubic in.

2. Divide the volume by the area:

207 / 20.7 = 10

The height is 10 inches.

Answer:

Step-by-step explanation:

The formula of a volume of a cylinder:

[tex]V=Bh[/tex]

B - base area

h - height

1. We have

h = 5in, B = 20 in².

Substitute:

[tex]V=(5)(20)=100\ in^3[/tex]

2. We have

B = 20.7 in², V = 207 in³.

Substitute:

[tex]207=20.7h[/tex]            divide both sides by 20.7

[tex]\dfrac{207}{20.7}=\dfrac{20.7h}{20.7}\\\\10=h\to h=10\ in[/tex]

x+7y = -77

Step-by-step explanation:

multiply both sides by 7 to get rid of denominator

7y = -x-77

now move x term to other side

x+7y = -77

The average temperature of 7 degrees below normal can be represented as the integer '-7'. This is because in mathematics, a 'below' situation often equates to a negative value.

The situation describes 'an average temperature of 7 degrees below normal'. In the context of integers, 'below' generally refers to a negative value. Hence, we would represent this situation with the integer '-7'. This is because a below normal temperature is often regarded as a decrease or loss, which is conventionally represented in mathematics as a negative value.

Final answer:

The letter J is formed by the opposition movement of the thumb toward the fingers of the same hand.

Explanation:

The subject of this question is Biology, specifically the anatomy of the hand and the movement of the thumb.

The letter J is formed by sticking up the smallest finger and folding all the other fingers into the palm of your hand with the thumb folded over them. This hand movement is an example of the opposition movement of the thumb toward the fingers of the same hand, which allows us to grasp and hold objects.

The thumb joint, which can move back and forth and up and down, but more freely than the wrist or fingers, plays a key role in the formation of the letter J.

Answer:

Step-by-step explanation:

speed = distance/time

so renaldo speed = 3.2/0.5 = 6.4miles/hr (since time taken is 1/2 hr)

now after 1 hr of his appoinment i.e at 5:30pm he took bus whose speed is same as before i.e 6.4 miles/hr

now time taken to cover this 4.8 miles = 4.8/6.4 = 3/4 hr (since time = distance /speed )

3/4 hr = 3/4 * 60 = 45 minutes

so he reached at 6:15pm . so he will be on time.
