Can someone help ???

Answer:

width of given rectangle = 6 cm

length of given rectangle =  4 cm

Step-by-step explanation:

Let the breadth be x cm

given that

The length of a rectangle is eight centimeters less than twice its width

length of rectangle in terms of x =  2(breadth ) - 8 =  2x - 8

we know perimeter of rectangle is given = 2(l + b)

thus, perimeter of given rectangle is = 2 ( x +  2x - 8) = 6x - 16

also given perimeter of the rectangle is 20 centimeters

thus,

6x - 16 = 20

6x = 20 + 16 = 36

x = 36/6 = 6

Thus,

width of given rectangle = 6 cm

length of given rectangle = 2*6 - 8 = 4 cm

Suppose that the number of the people in the party is :

[tex]x[/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

20 % of x equals :

[tex] \frac{20}{100} \times x = 0.2x \\ [/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Thus ;

[tex]0.2x = 6[/tex]

[tex] \frac{2}{10}x = 6 \\ [/tex]

Multiply sides by 10

[tex]10 \times \frac{2}{10} x = 10 \times 6 \\ [/tex]

[tex]2x = 60[/tex]

Divided sides by 2

[tex] \frac{2}{2} x = \frac{60}{2} \\ [/tex]

[tex]x = 30[/tex]

There were 30 people in the party.

Thus there are ;

[tex]30 + 6 = 36[/tex]

People at the party now.

Answer:

23.55

Step-by-step explanation:

To calculate the area I did the following equation

area = 3.14 (r) (r)

area = 3.14 (3) (3)

area = 28.26

The area is 28.26 but the question is asking how much gravel would be needed to fill 5/6 of the area.

The equation for 5/6 out of 28.26 is

28.26 (5/6) = 23.55

So the final answer is (a.) 23.55 sq. ft.

Answer:

odd

Step-by-step explanation:

Answer: 1. $1.80

2. $21.80

Step-by-step explanation:

You apply sales tax to 20 which is 9% or 0.09 so you p multiply 20 by 0.09 which is 1.8. That’s the tax then add that to 20 and get 21.80

Hey there!

In order for you to convert/ express a fraction as a decimal you SHOULD:

DIVIDE the numerator (the TOP number) from the denominator (the BOTTOM number)

Now that we have that guide/side note we can answer your question, shall we?

52/ 9 = 5.777778

If you’re rounding to your Answer, then it’ll be: 5.78

Overall answer is: 5.777778 ✅

Good luck on your assignment and enjoy your day!

Step-by-step explanation:

Answer:

Step-by-step explanation:

I am assuming you want an equation

y=mx + b

m is the slope, and b is the y intercept, so just fill in the info

y=-2x + 0

because it is just + 0, you can simply write:

y=-2x

Step-by-step explanation: 12/3 can be written as 4

This number can be written as a rational number, a natural number, and a whole number.

Therefore, 12/3 is not only a rational number.

Answer:

6x-2

Step-by-step explanation:

Celia’s simplified expression:

6x - 2.

The last option is  correct.

One mathematical expression makes up a term. It might be a single variable (a letter), a single number (positive or negative), or a number of variables multiplied but never added or subtracted. Variables in certain words have a number in front of them. A coefficient is the number used before a phrase.

Given Phrase:

Celia simplified the expression Negative 4 x (1 minus 3) minus (2 x + 2).

That means,

-4x(1 -3) - (2x +2).

She checked her work by letting x = 5 in both expressions.

That means,

-4(5)(1 -3) - (2(5) +2).

= 40 - 12

= 28.

To find the simplified expression:

-4x(1 -3) - (2x +2),

= 6x - 2.

Therefore, the required expression is 6x - 2.

Step-by-step explanation:

Answer:

C. 3

Step-by-step explanation:

Formula for slope is given as [tex] m = {y_2 - y_1}{x_2 - x_1} [/tex]

The coordinates of any two points can be used in this formula. Let's use, (1, 5) and (2, 8).

Let,

[tex] (1, 5) = (x_1, y_1) [/tex]

[tex] (2, 8) = (x_2, y_2) [/tex]

Plug the values into the formula:

[tex] m = {8 - 5}{2 - 1} [/tex]

[tex] m = {3}{1} [/tex]

[tex] m = 3 [/tex]

Answer:

0.3125

Step-by-step explanation:

in decimal form. Use our fraction to decimal calculator to convert any fraction to a decimal and to know if it is a terminating or a recurring (repeating) decimal.

Answer:

0.3125

Step-by-step explanation:

Answer:

Step-by-step explanation:There are formulas to work this out, but you can also suss out an answer by a liberal application of critical thinking.

Okay, you want to add 51 + 52 + 53 + … + 99 + 100, right? (The … represents all the numbers in between, in case you were wondering.)

Well, that’s a total of 50 numbers. And if you know anything about addition, you know that it doesn’t matter what order you add them.

So you could also say 51 + 100 + 52 + 99 + 53 + 98 + … and so on.

Let’s see what happens. 51 + 100 = 151. So far so good.

Then, 52 + 99 also equals 151. And 53 + 98 also equals 151. Since there are 50 numbers, that’s 25 pairs that are going to add up to 151.

151 + 151 + 151 + 151 + … (21 more instances of 151).

So we can simplify our workload a bit. Instead of adding up all the numbers by hand, we can just multiply 151 by 25.

151 x 25 = 3775

From that, we can work out a generic formula that will allow you to add any sequence of numbers…without actually adding.

Let a be the first number in the sequence, and let n be the last number in the sequence. The number of numbers is (n - a) + 1. (You have to add 1, because if you just subtract, it’s like you’re losing the lowest number in the sequence).

So…you get the sum by adding the first and last number in the sequence, and then multiplying that result by half of the total number of numbers.

(a+n)((n−a)+12)  

an−a2+a+n2−an+n2  

−a2+a+n2+n2  

−a(a−1)+n(n+1)2  

Let’s check to see if it works!

−51(51–1)+100(100+1)2  

−51(50)+100(101)2  

−2550+10,1002  

75502  

3775  

Note that if the starting number were 1, the formula would simplify to  n(n+1)2

Following are the calculation to the sum of integers:

Given:

33 to 47

To find:

Sum of integers=?

Solution:

Given numbers:

33 to 47

[tex]\to \bold{33,34,35,36,37,38,39,40,41,42,43,44,45,46,47}[/tex]

Using formula:

[tex]\bold{S = \frac{n(a + l)}{2}}[/tex]

[tex]n=15\\\\a=33\\\\l=47 \\\\ \bold{S = \frac{15(33 + 47)}{2}}\\\\[/tex]

    [tex]\bold{= \frac{15(80)}{2}}\\\\\bold{= \frac{1200}{2}}\\\\\bold{= 600}[/tex]

Therefore, the sum of the integers "600".
