What is the answer
5x2 + bx - 7 b=?

Answer:

270 cm²

Step-by-step explanation:

The question is not complete, but a similar question is attached.

Solution:

A prism is a three dimensional polygon with two identical and opposite faces. These bases are called the base of the polygon.

A triangular prism is a prism in which its bases are triangular in shape and it also has three rectangular sides.

The total surface area (TSA) of a triangular prism is given by:

TSA = area of triangle 1 + area of triangle 2 + area of rectangle 1 + area of rectangle 2 + area of rectangle 3

Area of triangle 1 = (1/2) * base * height = 1/2 * 6 * 5 = 15 cm²

Area of triangle 2 = (1/2) * base * height = 1/2 * 6 * 5 = 15 cm²

Area of rectangle 1 = length * breadth =15 * 6 = 90 cm²

Area of rectangle 2 = length * breadth =15 * 5 = 75 cm²

Area of rectangle 3 = length * breadth =15 * 5 = 75 cm²

TSA = 15 cm² + 15 cm² + 90 cm² + 75 cm² + 75 cm² = 270 cm²

Answer:

n=-3.1

Step-by-step explanation:

To solve this, first subtract 3 from both sides of the equation to get 2n=-6.2. Next, divide both sides of the equation by 2 n order to get the final answer of n=-3.1

Answer:

54 miles

Step-by-step explanation:

Answer:

x = 14

Step-by-step explanation:

alanton is 16 miles from oakley,  8 miles from crawfod and 28 miles from fayeville

Make sure to draw the distances on the figure correctly.

We have similar triangles

AC       CD

------ = ---------

BC       CE

8          x

------ = ---------

16       28

Using cross products

8 * 28 = 16*x

224 = 16x

Divide each side 16

224/16 = 16x/16

14

The distance is 14

We have right triangles so we can find length y

y^2 + 16^2 = 28^2

y^2 = 28^2 - 16^2

y ^2 =528

y = sqrt(528)

We can find the length of AC

AC^2 +

We have right triangles so we can find length y

y^2 + 16^2 = 28^2

y^2 = 28^2 - 16^2

y ^2 =528

y = sqrt(528)

Answer:

andre has more money

Step-by-step explanation:

Answer:

You need to write an equation for each.

For Andre, he has 100 dollars, and every week gets 5 dollars more. You add the 5 dollars, and Since you don't know how many weeks it has been, use a variable.

100 + 5w

For Elena, she has 10 dollars, and gets 20 each week.

10 + 20w

Now that you know that it has been 4 weeks, you can plug in 4 for the variable for weeks.

Andrew:

100 + 5(4) =120

Elena

10 + 20(4) ==90

Andrew has more money in this time.

To find when they have the same amount, equal their expressions to each other. This means that they will have the same amount (because they are equalled) and you can solve to find the variable, which means the weeks that they are equal at.

Bring the like terms to each side by canceling them out. Since you have positive 10, then subtract 10 to each side. You have 5w, so subtract 5w to each side.

90+5w=20w

90=15w

90÷15=6

6=w

The answer will simplify down to 6 weeks.

-6

Answer:

1/5

Step-by-step explanation:

In order to find the answer, we need to isolate the "n."

Get 5 to the other side by dividing both sides by 5

(n-1/10)= 1/2 ÷(5)

Multiply the 2 and the 5 of the equation.

(n-1/10)= 1/10

Next, move the fraction on the left side, to the right.

n= 2/10

Reduce.

n= 1/5

Using linear function concepts, it is found that:

A linear function is modeled by:

Answer:

24

Step-by-step explanation:

Answer:

x = 56, x = 30

Step-by-step explanation:

(a)

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 5, then

sum = 180° × 3 = 540°

sum the interior angles and equate to 540

72 + 2x + 99 + 89 + 3x = 540, that is

5x + 260 = 540 ( subtract 260 from both sides )

5x = 280 ( divide both sides by 5 )

x = 56

----------------------------------------------------------------

(b)

The sum of the exterior angles of a polygon = 360°

sum the exterior angles and equate to 360

94 + 56 + 4.5x + x + 1.5x = 360, that is

7x + 150 = 360 ( subtract 150 from both sides )

7x = 210 ( divide both sides by 7 )

x = 30

Answer:

Please check the explanation.

Step-by-step explanation:

Given

height of cylinder h = 4 inches

Given the table

Radius          Volume

1                     ___

2                    ___

3                    ___

Determining the Volume of the cylinder when r = 1 inch and h = 4 inches

Given

h = 4 inches

r = 1 inch

Using the formula to determine the volume of the cylinder

V = πr²h

V = 3.14×(1)²×(4)

V = 3.14 × 1 × 4

V = 12.56

V ≈ 13  (nearst cubic inch)

Therefore, the volume of cylinder when h = 4 inches and r = 1 inch will be:

V ≈ 13 cubic inches (nearest cubic inch)

Determining the Volume of the cylinder when r = 2 inches and h = 4 inches

Given

h = 4 inches

r = 2 inch

Using the formula to determine the volume of the cylinder

V = πr²h

V = 3.14×(2)²×(4)

V = 3.14 × 4 × 4

V = 50.24

V ≈ 50  (nearst cubic inch)

Therefore, the volume of cylinder when h = 4 inches and r = 2 inches will be:

V ≈ 50 cubic inches (nearest cubic inch)

Determining the Volume of the cylinder when r = 3 inches and h = 4 inches

Given

h = 4 inches

r = 3 inch

Using the formula to determine the volume of the cylinder

V = πr²h

V = 3.14×(3)²×(4)

V = 3.14 × 9 × 4

V = 113.04

V ≈ 113  (nearst cubic inch)

Therefore, the volume of cylinder when h = 4 inches and r = 3 inches will be:

V ≈ 113 cubic inches (nearest cubic inch)

Therefore, we complete the table conclude such as:

Radius          Volume

1                     13

2                    50

3                    113

y be the minutes ensemble acts lasts

According to given statement;

Angle: A figure formed by two rays or line ... Time Period 3: Geometric Relationships & Properties, 15 blocks ... dilation of the polygon with that point as the center. Identify the scale factor that you used. G-SRT 2. Given two figures, use the ... the circle centered at the origin and ... Write an equation for a circle with a radius of 2.

Step-by-step explanation:

The equation of the line of dilation centered at the origin with a scale factor of k=3 is,

⇒ y' = (6/5)x + 3.

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Now, To find the equation of the line of dilation centered at the origin with a scale factor of k=3,

we need to apply the dilation transformation to the given equation.

First, we need to rewrite the equation in slope-intercept form:

-2x + 5y = 15

5y = 2x +15

y = (2/5)x + 3

Now, we can apply the dilation transformation by multiplying the slope by the scale factor k = 3;

y' = k y

y' = 3 (2/5)x + 3

y' = (6/5)x + 3

Therefore, the equation of the line of dilation centered at the origin with a scale factor of k=3 is,

y' = (6/5)x + 3.

Answer:

(2,-10)

x=2

y= -10

Step-by-step explanation:

To solve by combining the equations we first need to get everything in linear form.

For both equations we can simply just add y to both sides and then subtract the other number on the right side. Doing this gets us

-2x-6=y

-7x+4=y

We then set the two equations equal to each other and solve for y

-2x-6= -7x+4

add 7x and 6 to both sides and get

5x=10

x=2

Use this x value and plug it into any equation

let's do it on the first

-2(2)-y=6

Solve for y and get

-y=10

which means  that

y= -10
