Answer:

35m

Step-by-step explanation:

length = 2+w

width = w

Perimeter = 2(length)+2(width)

24 = 2(2+w)+2(w) =  4+2w+2w = 4+4w

24=4+4w

4w=20

w=5

width =5

length = 2+5 = 7

Area = (length)(width) = 5(7) = 35m

Answer:

1.09

Step-by-step explanation:

0.65 + Percentage increase =

0.65 + (68% × 0.65) =

0.65 + 68% × 0.65 =

(1 + 68%) × 0.65 =

(100% + 68%) × 0.65 =

168% × 0.65 =

168 ÷ 100 × 0.65 =

168 × 0.65 ÷ 100 =

Answer:

x = 5

Step-by-step explanation:

We know that adding up all the degrees in a triangle will give you 180. So, subtracting the given angle from 180 will give us the sum of the missing angles: 180 - 88 = 92.

Since the diagram shows us that the triangle is isoscles, we know that the missing two angles are the same and equivalent. So, in order to get the value of one angle, we divide the sum of angles by 2: 92/2 = 46.

Now that we've found the value of one angle, we set it equal to the equation given to find the value of x: 9x + 1 = 46.

Last but not least, solve for x: 9x = 45 --> x = 5

Answer: cost of T-shirts = $18

cost of sweatshirt = $42

Step-by-step explanation:

Let the cost of T-shirts be x

Let the cost of sweatshirt be y

The information given in the question can be used to form an equation that'll be:

9x + 3y = 288 ...... i

1x + 6y = 270 ........ ii

Multiply equation i by 1

Multiply equation ii by 9

9x + 3y = 288 ....... iii

9x + 54y = 2430 ..... iv

Subtract iii from iv

51y = 2142

y = 2142 / 51

y = 42

The cost of a sweatshirt is $42

Since Carson sells 1 T-Shirt and 6 sweatshirts for 270$. The cost of a t-shirt will be:

= 270 - 6(42)

= 270 - 252

= $18

Answer:

a = 7

Step-by-step explanation:

a = 3 + 4

Answer:

x            y = x-5            y              (x, y)

6            y = 6-5           1               (6, 1)

0            y = 0-5          -5              (0, -5)

5            y = 5-5          0               (5, 0)

-2           y = -2-5        -7               (-2, -7)

The graph of the line y = x-5 is attached below.

Step-by-step explanation:

Given the function

y = x-5

substitute x = 6 in the function

y = 6-5 = 1

so

y = 1

(x, y) = (6, 1)

substitute x = 0 in the function

y = x-5

y = 0-5 = -5

so

y = -5

(x, y) = (0, -5)

substitute x = 5 in the function

y = x-5

y = 5-5 = 0

so

y = 0

(x, y) = (5, 0)

substitute x = -2 in the function

y = x-5

y = -2-5 = -7

so

y = -7

(x, y) = (-2, -7)

Hence, the table becomes

x            y = x-5            y              (x, y)

6            y = 6-5           1               (6, 1)

0            y = 0-5          -5              (0, -5)

5            y = 5-5          0               (5, 0)

-2           y = -2-5        -7               (-2, -7)

The graph of the line y = x-5 is attached below.

Answer:

1/a^8/5 for the first, 9b^8/3 for the second, and 8x^25/7 for the third

Step-by-step explanation:

1) With neg exponents, you can just take it and flip it, and make the exp pos i.e. 1/a^8/5

2) When there is an exponent outside of parenthesis of a number with an exponent, you multiply the exponents together i.e. 9b^8/3

3) The same applies to this as the 2nd, we just multiply to get 8x^25/7

Step-by-step explanation:

this is because if it says total it means the addition of those numbers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the points

Finding the slope between (-1, -2) and (2, 4)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-1,\:-2\right),\:\left(x_2,\:y_2\right)=\left(2,\:4\right)[/tex]

[tex]m=\frac{4-\left(-2\right)}{2-\left(-1\right)}[/tex]

[tex]m=2[/tex]

Using the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = 2 and the point (-1, -2)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y -(-2) = 2(x-(-1)[/tex]

Thus, the point-slope form of the line equation is

[tex]y -(-2) = 2(x-(-1)[/tex]

now, write the slope-intercept form of the line equation y = mx+b

[tex]y-\left(-2\right)=2\left(x-\left(-1\right)\right)[/tex]

[tex]y+2=2\left(x+1\right)[/tex]

subtract 2 from both sides

[tex]y+2-2=2\left(x+1\right)-2[/tex]

Simplify

[tex]y=2x+0[/tex]

[tex]y = 2x[/tex]

Therefore, the equation in slope-intercept form is:

Answer:

c = 45h + 25

Step-by-step explanation:

The only difference between what the electrician used to charge and what he/she charges now is an increase of $5. Therefore, instead of charging $40 he is now charging $45. Using this new information we can create the following equation to calculate the total cost of a job. We do this by multiplying the cost per hour ($45) by the total number of hours (h) and then adding the surcharge.

c = 45h + 25

Answer:

p = 16/8 = 2

Step-by-step explanation:

We know that the pencils were divided into 8 groups of 2.

Then the total number of pencils is equal to 8  (the number of groups) times 2 (the number of pencils in each group)

8*2 = 16

The total number of pencils is 16.

Then the operation of dividing 16 pencils into 8 groups is written as:

16/8

And we know that this is equal to 2, then the operation is:

16/8 = 2.

Then the equation is:

p = 16/8 = 2

where p represents the number of pencils in each group.

Answer:

120%

Step-by-step explanation:

Given that,

The diameter of the raw cookie is 2 1/2 inches i.e. 5/2 inches

After baking the cookie, the diameter is 5 1/2 inches i.e. 11/2inches

We need to find by what factor does the cookie expand.

[tex]x=\dfrac{5\dfrac{1}{2}-2\dfrac{1}{2}}{2\dfrac{1}{2}}\times 100\\\\=\dfrac{\dfrac{11}{2}-\dfrac{5}{2}}{\dfrac{5}{2}}\times 100\\\\=120\%[/tex]

So, the cookie will expand 120%.
