what is the area of this triangle ?!

Answer:

F1(x) = 4x-9 Thats the answer

Answer:

x = 2

Step-by-step explanation:

5(x + 1) = 4x + 7

5x + 5 = 4x + 7

x + 5 = 7

x = 2

Answer:

x=2

Step-by-step explanation:

Let's solve your equation step-by-step.

5(x+1)=4x+7

Step 1: Simplify both sides of the equation.

5(x+1)=4x+7

(5)(x)+(5)(1)=4x+7(Distribute)

5x+5=4x+7

Step 2: Subtract 4x from both sides.

5x+5−4x=4x+7−4x

x+5=7

Step 3: Subtract 5 from both sides.

x+5−5=7−5

x=2

Answer:

(x-10)²+(y+9)²= 324.

Step-by-step explanation:

For this question, you will need to substitute these values into the equation of a circle:

(x-h)²+(y-k)²= r²

'h and k' represent the center points, and 'r' represents the radius.

This will result in:

(x-10)²+(y+9)²=324.

Answer:

84.6

Step-by-step explanation:

135c + 273.15 = 408 K

72C + 273.15 = 345 K

100 L over 408 K = V2 over 345 K

V2= 84.6

The volume of the gas when temperature decreases to 72.0 °C is 84.6 L

Volume is a physical quantity that measures the amount of three-dimensional space occupied by matter (solid, liquid, or gas).

Volume is defined as the three-dimensional space occupied by matter or enclosed by a surface. The SI unit of volume is the cubic meter (m³),

Given that, a sample of gas has a volume of 100.0 L at 135 °C, the pressure remains constant, we need to find that what is the volume of the gas when temperature decreases to 72.0 °C

Converting the temperature into Kelvins =,

135C + 273.15 = 408 K

72C + 273.15 = 345 K

100 L / 408 K = V2 / 345 K

V2 = 84.6

Hence, the volume of the gas when temperature decreases to 72.0 °C is 84.6 L

Based on the vertical angles theorem, the measure of angle 1 is: 48°.

Vertical angles are always directly opposite each other and are formed when two straight lines crosses each other.

In the diagram given, the angle that is directly opposite angle is 48°, since it is an alternate angle to 48° formed on lines m and n (lines k and l are parallel lines).

Step-by-step explanation:

Vertex: (250,300)

Minimum height is 300 when the horizontal distance is 250

Step-by-step explanation:

Step 1:  Find the smallest height

If you look at the graph, you can tell that at 250 feet, the height in feet is the lowest and it is at 250.  Therefore, the vertex is also (250, 250).  But, we are just looking for the x-value which will be 250.

Answer:

220 square centimeters  Option c.

Step-by-step explanation:

There are 6 faces of a rectangular prism, so to find the surface area of the prism, add the area of each faces.

Surface Area = 2(lw + lh + wh)

where, l = Length, w = Width and h = Height of the rectangular prism.

According to the given dimensions

Length = 10 cm

Width = 4 cm

Height = 5 cm

Therefore, the surface area of the given rectangular prism will be,

S.A. = 2((10)(4) + (10)(5) + (5)(4))

       = 2(40 + 50 + 20)

       = 2 (110)

      = 220 cm²

Surface area of the rectangular prism will be 220 cm².

We have been given that a rectangular prism that has a height of 5 cm, a width of 10 cm, and a depth of 4 cm. We are asked to find the surface area of the prism.

We will use surface area of rectangular prism to solve our given problem.

[tex]A=2(lw+wh+hl)[/tex], where,

l = Length,

w = Width,

h = Height.

[tex]A=2(10\text{ cm}\cdot 4\text{ cm}+4\text{ cm}\cdot 5\text{ cm}+5\text{ cm}\cdot 10\text{ cm})[/tex]

[tex]A=2(40\text{ cm}^2+20\text{ cm}^2+50\text{ cm}^2)[/tex]

[tex]A=2(110\text{ cm}^2)[/tex]

[tex]A=220\text{ cm}^2[/tex]

Therefore, the surface area of the given prism would be [tex]220\text{ cm}^2[/tex] and option C is the correct choice.

Answer:

well im not sure but that's what i got

Step-by-step explanation:

(20)(12)(10)=2400

2400/4= 800

The volume of the given rectangular prism is 2400 cubic inches.

Given that, a rectangular prism dimensions are length = 20 inches, width = 12 inches and height = 10 inches.

A rectangular prism is a three-dimensional solid shape with six faces that including rectangular bases. A cuboid is also a rectangular prism. The cross-section of a cuboid and a rectangular prism is the same.

Volume of a rectangular prism = Area of a base × Height.

Here, Area of a base = length × width

= 20 × 12

= 240 square inches

So, volume = 240 × 10

= 2400 cubic inches

Therefore, the volume of the given rectangular prism is 2400 cubic inches.

Step-by-step explanation:

Answer: a, the amount of money in Michaels bank account

Step-by-step explanation:

Answer: Account A pays more interest. It pays $10 more.

Step-by-step explanation:

The following information can be derived from the question:

Principal= $1000

Account A rate= 5%

Time = 1 year

Interest= (Principal × Rate × Time)/100

= ($1000 × 5 × 1)/100

= $5000/100

= $50

Account A pays interest of $50

Principal= $1000

Account B rate= 4%

Time = 1 year

Interest= (Principal × Rate × Time)/100

= ($1000 × 4× 1)/100

= $4000/100

= $40

Account B pays interest of $40

From the solutions provided, Account A pays more interest. This is calculated as: $50 - $40 = $10

Answer:

72 cm

Step-by-step explanation:

The area (A) of a kite is calculated as

A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ( d₁ and d₂ are the diagonals )

Here A = 900 and d₁ = 25, thus

[tex]\frac{1}{2}[/tex] × 25 × d₂ = 900 ( multiply both sides by 2 )

25d₂ = 1800 ( divide both sides by 25 )

d₂ = 72 cm

Answer:

The average force applied to the ball is 84N

Step-by-step explanation:

This problem bothers on the impulse of a force

Given data

Mass of ball m= 0.28kg

Initial speed u= 0m/s

Final speed v= 6m/s

Time of impact t= 0.02s

We know that the impulse of a force

Ft= mv-mu

Hence the force is

F= (mv-mu)/t

F=m(v-u)/t

F= 0.28(6-0)0.02

F= 1.68/0.02

F= 84N

Answer:

C features a slope of +4 and a y-intercept of +2

Step-by-step explanation:

Only the middle two answers feature a slope of +4, so eliminate answers A and D.  Answer C features a slope of +4 and a y-intercept of +2

The equation of a line in slope-intercept form for a line with slope 4 and y-intercept at (0, 2) is C. y = 4x + 2.

In the slope-intercept form of a linear equation, y = mx + b, 'm' represents the slope and 'b' represents the y-intercept. If we substitute the given values into this equation, with m = 4 (the slope) and b = 2 (the y-coordinate of the y-intercept), we get y = 4x + 2. So, the correct answer is C. y = 4x + 2.
