Answer:

3x + 2

Step-by-step explanation:

The height of a poster is 7x+10 and its perimeter is 20x+24 . What is the width of the poster?

The shape of a poster = Rectangular shape

Hence:

The Perimeter of a Rectangle (Poster) = 2L + 2W

Where:

Length = Height = 7x + 10

Perimeter = 20x + 24

Therefore:

20x + 24 = 2(7x + 10) + 2W

20x + 24 = 14x + 20 + 2W

2W = 20x + 24 - (14x + 20)

2W = 20x + 24 -14x - 20

2W = 6x + 4

W = (6x + 4)/2

W = 3x + 2

Therefore, the width of the poster

= 3x + 2

Answer:

Step-by-step explanation:

Let the cost of one t-shirt = t

And the cost of one sweatshirt = s

Since, Jayden sells 9 t-shirts and 3 sweatshirts for $420,

9t + 3s = 420

3t + s = 140 --------(1)

And Carson sells 1 t-shirt and 6 sweatshirts for $296,

t + 6s = 296 ----------(2)

Equation (1) multiplied by 6 then subtracted from equation (2)

(t + 6s) - 6(3t + s) = 296 - 6(140)

(t - 18t) + (6s - 6s) = 296 - 840

-17t = -544

t = $32

From equation (1),

3(32) + s = 140

s = 140 - 96

s = $44

This solution shows that cost one t-shirt is same for both sellers Carson and Jayden.

Answer:

The hike is 4.5 miles

Step-by-step explanation:

We divided 3 by 2 since 3 is 2/3 done

3 ÷ 2 = 1.5

So now we know what 1/3 is; 1.5

So now we multiply 1.5 by 3

1.5 × 3 = 4.5

Thus, the hike is 4.5 miles long

Answer:

5.2 cubic ft

Step-by-step explanation:

took the test

The volume of given cone is 5.23 cubic feet.

Volume is the measure of the capacity that an object holds.

[tex]v = \frac{1}{3} \pi r^{2} h[/tex]

where,

v is the volume of cone

r is the radius of cone

h is the height of cone

According to the question we have

Diameter of cone is 2ft

⇒ radius of the cone = [tex]\frac{2}{2} = 1 feet[/tex]

Height of the cone is 5ft.

Therefore,

The volume of the cone  = [tex]\frac{1}{3}(1)\pi( 1)^{2} (5)[/tex]

Volume of cone = [tex]\frac{1}{3} (3.14)(1)(5) = 5.23 cubic feet[/tex]

Hence, hence the volume of given cone is 5.23 cubic feet.

Answer: $357

Step-by-step explanation: Please see images below!

The amount she have to spend to paint the wall is $357.

Surface area are derived for some standard shapes like circle, triangle, parallelogram, rectangle, trapezoid, etc.

When some shape comes which isn't standard figure, then we find its area by slicing it (virtually, like by drawing lines) in standard shapes. Then we calculate those composing shapes' area and sum them all.

Thus, we have:

[tex]\text{Area of composite figure} = \sum (\text{Area of composing figures})[/tex]

That ∑ sign shows "sum"

We are given that;

The side of two hexagon is 2ft, painting measures 9*25ft.

Now,

In this case, s = 2 feet. Therefore, the area of one hexagonal window is:

Area = (3√3 × 2²)/2 Area = (12√3)/2 Area ≈ 10.39 square feet

Since there are two windows, we need to multiply this by 2 and subtract it from the total area of the wall:

225 - (2 × 10.39) ≈ 204.22 square feet

This is the area that needs to be painted. To find how much Deb will have to spend, we multiply this by $1.75 per square foot:

204.22 × $1.75 ≈ $357.39

Rounding this to the nearest dollar, we get:

$357

Therefore, by the area of painting the answer will be $357.

Answer:

43 + 25 = x

x = 68

Answer:

43+25=y

68=y

Step-by-step explanation:

Answer:

Step-by-step explanation:

Question (1)

x² + 10x + 12

= x² + 2(5x) + 5² - 5² + 12

= [x² + 2(5x) + 5²] - 5² + 12

= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]

= (x + 5)² - 13

Question (2)

y² - 6y - 15

= y² - 2(3y) - 15

= y² - 2(3y) + 3² - 3² - 15

= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]

= (y - 3)² - 3²- 15

= (y - 3)² - 9 - 15

= (y - 3)² - 24

The worth of the TV after 3 years is £809.90208

Step-by-step explanation:

The answer to given question can be found from the anual depreciation formula and solving for the Future Value (F. V.) of the machine

The given parameters of the TV are;

The amount at which Collin buys the TV, P = £720

The rate at which the TV depreciates at, R = 4%

The number of years the depreciation is applied, T = 3 years

The amount the TV is worth after three years, 'A', is given as follows;

[tex]A = P \cdot \left(1 + \dfrac{R}{100} \right )^T[/tex]

By plugging in the known values, we have;

[tex]A = 720 \cdot \left(1 + \dfrac{4}{100} \right )^3 = 809.90208[/tex]

The amount the TV is worth after three years, A = £809.90208

Step-by-step explanation:

Answer:

a) "impossible event"

b) "certain event"

c) Letter A.

Step-by-step explanation:

a) An event with probability 0 is said to be:

These events are called "impossible events" (but there are more complex cases where we can have probabilities 0, and the events are not necessarily impossible events)

b) An event with probability 1 is said to be

An event with a probability of 1 is an event that will happen, these events are called "certain event"

c) The probability for each outcome of an unbiased experiment of N different outcomes will be 1/N

for example, for a 6-side dice we have 6 outcomes, then the probability of each outcome is 1/6.

For the coin, we have 2 outcomes, then the probability of each outcome is 1/2

Probability of getting a head = 1/2 = 0.5

In the image, we can see that letter A is on the 0.5 value, then the correct answer here is A.
