Answer:

  240 square feet

Step-by-step explanation:

The area of a composite figure can be found by adding the areas of its parts.

__

Extending the vertical line across the figure cuts off a rectangle on the left that is 18 ft long and 10 ft high. It cuts off a triangle on the right that has a base of 20 ft and a height of 24-18 = 6 ft.

The sum of the areas of these parts is ...

  rectangle area + triangle area

  = (10 ft)(18 ft) +1/2(20 ft)(6 ft) = 180 ft² +60 ft²

  = 240 ft² . . . . area of the figure

_____

Additional comment

You can see that this is the product of the height of the rectangle and the overall length of the figure. This means the smaller triangles that stick above or below the horizontal lines would fit exactly into the spaces at the tip of the arrow, filling in a 10 ft × 24 ft rectangle.

Answer:

52 pints

Step-by-step explanation:

Given;

2 pints = 1 quart

To Find;

How many pints are in a 26-quart container

Solve;

Since 2 pints = 1 quart

Then the Formula = divide the volume value by 2

The equation for 2 pints = 1 quart is 2 ÷ x = 1

which x = 2.

Thus, the equation for 26 quart container = how many pints =

x ÷ 2 = 26

Divide/Multiply sides by 2

2x/2 = 26 * 2

Simplify

x = 52

Hence, there are 52 pints in a 26 quart container

Hello

if h(x) = [tex]x^{2} -5x+7[/tex] so the value of  [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex].

A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. The meanings of the word equation and its cognates in other languages can vary slightly. For instance, in French, an equation is defined as having one or more variables, whereas, in English, an equation is any well-formed formula that consists of two expressions linked by the equals sign.

Finding the values of the variables that result in equality is the first step in solving an equation with variables. The variables that must be included in the equation are also known as the unknown.

we have h(x) = [tex]x^{2} -5x+7[/tex]

So, substitute the value [tex]x=-8[/tex] in the equation,

h([tex]-8[/tex]) = [tex](-8)^{2} -5(-8)+7[/tex]

        = [tex]64+40+7[/tex]

        = [tex]111[/tex]

And now we shall multiply it with [tex]\frac{1}{3}[/tex],

we get, [tex]\frac{1}{3}[/tex]× [tex]h(-8)[/tex] = [tex]\frac{111}{3}[/tex]

Answer: n=6

Step-by-step explanation:

First you subtract 18 from both sides so that it become -1/2n^2=-18

Second divide both sides by -1/2 so it becomes -18/(-1/2)=n^2

Then you simplify and get n^2=36

Finally you find the square root of both side, and you get n=6

Answer:

She took 28 shots, 7 shots would be the remaining 25% so you multiply it by 4 to get 100% or 7 × 4 = 28

missed shots = 7 = 25%             since 75% are successful

proportionality table

25% ...............7

100% ........... = 7 x 100% : 25% = 28

total = 28 shots

Answer:

C

Step-by-step explanation:

Answer:

5.89 dollars

Step-by-step explanation:

To find the unit price, we use t/q where t is the total price and q is the quantity.

Therefore, it costs 5.89 dollars for a pair of gloves.

The unit price of the pair of gloves will be $8.79 for each pair of gloves.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

A package of 5 pairs of insulated gloves costs ​$43.95. Then the unit price of the pairs of gloves is calculated as,

Rate = $43.95 / 5

Rate = $8.79 for each pair of gloves

The unit price of the pair of gloves will be $8.79 for each pair of gloves.

Answer:

-8m^5+10m^4+9m^3-16m^2+5

Step-by-step explanation:

PLATO

The standard form is ( -8m⁵+10m⁴+9m³-16m²+15m ).

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The expression will be solved as:-

E = ( 3m² - m )( 4m³ + m - 5 )

E = -8m⁵ - 2m⁴ + 10m³ - 15 m² - 4m³ - m² + 5m

E =  ( -8m⁵+10m⁴+9m³-16m²+15m ).

Therefore, the standard form will be ( -8m⁵+10m⁴+9m³-16m²+15m ).
