The height of a trapezoid  is 3cm

The formula for the area of a trapezoid is:

A = 1/2(base1 + base2)  × height

Where base1 and base2 are the lengths of the parallel sides of the trapezoid, and height is the distance between the bases.

That is:

A = 1/2(a+b)h

To  determine the height of a trapezoid using the formula substituting the given values and solve for h. That is:

A = 1/2(a+b)h

where A = 24 cubic centimeters, a = 9 cm and b = 7cm

24 = 1/2(9+7)h

24 = 1/2(16)h

24 = 8h

8h = 24

h = 24/8

h = 3 cm

The length of the third side of the triangle is x + 13.

A triangle is simply a two-dimensional polygon with 3 sides and 3 interior angles.

The perimeter of a triangle is the sum of the length of all three sides of the triangle.

Given the data in the question;

To find side C, equate the sum of all three sides of the triangle to the perimeter and simplify.

Side A + Side B + Side C = P

5x + ( 3x - 7 ) + Side C = 9x + 6

5x + 3x - 7 + Side C = 9x + 6

8x - 7 + Side C = 9x + 6

Side C = 9x + 6 - ( 8x - 7 )

Side C = 9x + 6 - 8x + 7

Side C = x + 13

Therefore, side C is x + 13.

Option A) x + 13 is the correct answer.

Answer:

142 bags

Step-by-step explanation:

0.5KG is half of a KG, so we can start by finding half of $9.90

$9.90/2 being $4.95

So each bag is $4.95

The total is $702.90

Dividing $702.90/$4.95 will equal the number of bags

702.9/4.95=142 bags

The probability of picking a green marble is 3/4 or 0.75. This means it is likely the event would occur. Therefore, option A is the correct answer.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, an experiment with a bag of marbles, P(green)=3/4.

Probability is used to determine how likely it is that a random event would happen. The probability that a random event occurs lie between 0 and 1.  The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.

The probability of picking a green marble is 3/4 or 0.75. 0.75 is more than 0.5. This means it is likely the event would occur.

Therefore, option A is the correct answer.

Compound interest describes interest on the principal plus interest.

Compound Interest Formula

The formula to find compound interest is [tex]A=P(1+\frac{r}{n})^{nt}[/tex]. In the formula:

We can plug in our information to find the rate.

Solving For Interest Rate

First, let's rewrite the equation with our information. Note that for simplicity I will write rounded values for each step, but in reality, no rounding should be done until the last step.

Then, simplify the exponent and divide both sides by 4700.

Take the 60th root of both sides.

Subtract 1 from both sides.

Finally, multiply both sides by 12.

This means that the rate is 0.04876. We can multiply this by 100 to get the rate as a percentage. The interest rate is 48.76%.

Answer:

EG = 44

Step-by-step explanation:

EG, the whole thing, is 10x - 16. It says that at the top of the image. But also, under the segment, we can put together two small pieces, EF and FG. So, the whole thing could also be 4x + 20.

The two expressions both describe EG. They are equal to each other. Write an equation.

10x - 16 = 4x + 20

subtract 4x

6x - 16 = 20

add 16

6x = 36

divide by 6

x = 6

They are asking for EG. Use either expression.

EG = 4x + 20

= 4(6) + 20

= 24 + 20

= 44

or,

EG = 10x - 16

= 10(6) - 16

= 60 - 16

= 44

Actually, its a neat check to do both ways bc it should come out the same.

EG = 44

To find the total cost of the pole at the store including sales tax, we need to multiply the price of the pole by the sales tax rate (expressed as a decimal).

$59.50 x 0.06 = $3.57

So the total cost of the pole at the store is $59.50 + $3.57 = $63.07.

To find the difference in price between the store and the website, we can subtract the website price from the store price:

$63.07 - $62.50 = $0.57

So the pole is $0.57 more expensive at the store than on the website.

To factor a trinomial of the form ax^2 + bx + c, you can use the following steps:

Step-by-step explanation:

To factor a trinomial of the form ax^2 + bx + c, you can use the following steps:

Find a factor pair of ac that has the sum of b. For example, if a = 2, b = -7, and c = -21, then the factor pair for -42 (2 * -21) that has the sum of -7 is (-7, -6).

Rewrite bx as a sum of those factors. In the example, -7x = -7x + (-6x).

Factor out the GCF (greatest common factor) from the two groups of terms. In the example, (2x - 7)(x - 6) = 2x(x - 6) - 7(x - 6) = 2x^2 - 14x + 12x - 42 = 2x^2 - 2x - 42.

Write the original trinomial as the product of two binomials. In the example, the trinomial 2x^2 + -7x + -21 can be factored as (2x - 7)(x - 6)

So the final factorization is (2x - 7)(x - 6)

It would take 2 hours for this space shuttle to travel 7. 2 x 108 miles

As per the given data, a certain space shuttle travels at a speed of 3. 6 x

104 miles per hour.

Here we have to determine that how many hours would it take this space shuttle to travel 7. 2 x 108 miles.

The relation between the speed and the distance is:

Speed = Distance × Time

Speed = 3. 6 x 104 miles per hour

Time = 1 hour

3. 6 x 104 = Distance × 1

Distance = 374.4 miles

The distance to be covered 7. 2 x 108 miles

= 777.6 miles

Hours taken to travel 7. 2 x 108 miles.

Time =  [tex]\frac{777.6 }{374.4}[/tex]

≅ 2 hours.

Answer: The graph of g(x) = 4x - 6 is a translation of the graph of f(x) = 4x - 3.

A translation of a function results in a shift of the graph of the function, either horizontally (left or right) or vertically (up or down).

When the graph of a function is shifted down, the y-coordinates of all the points on the graph decrease. When it's shifted to the left, the x-coordinates of all the points on the graph decrease.

In this case, the graph of g(x) = 4x - 6 is a vertical translation of 3 units down from the graph of f(x) = 4x - 3.

The y-coordinates of all the points on the graph of g(x) = 4x - 6 are 3 units less than the y-coordinates of the corresponding points on the graph of f(x) = 4x - 3.

Therefore, the correct answer is:

Translation of 3 units down.

The equation of the plane passing P (1,2,1) and orthogonal to the two planes: x-y-z-10 = 0, x-2y + z-2=0 is -3x-2y-z+8=0.

Equation of plane passing through (x1,y1,z1) is given by

A(x-x1)+B(y-y1)+C(z-z1)=0

where, A, B, and C are direction ratios

In the question, it is given that the plane passes through (1,2,1)

So, the equation of the plane will be in the form,

A(x-1)+B(y-2)+C(z-1)=0

It is also given that the plane is perpendicular to give 2 planes.

So, their normal to the plane would be perpendicular to the normal of both planes.

So, the required normal is a cross-product of the normals of planes

x-y-z-10=0 and x-2y+z-2=0

i.e,

-3i-2j-k=0

so, the direction ratios,

A=-3, B=-2, C=-1

putting the direction ratios in the previous equation of the plane,

-3(x-1)-2(y-2)-1(z-1)=0

-3x+3-2y+4-z+1=0

-3x-2y-z+8=0

The ratio of the volume of the cone to the volume of a prism is equal to one.

Three-dimensional space is quantified by volume. It is frequently measured quantitatively with SI-derived units (such the cubic metre and litre) or with a variety of imperial or US-standard units (such as the gallon, quart, cubic inch). Volume and height are related in how they are defined (cubed). The volume of a container is typically thought of as its capacity, or the amount of fluid (gas or liquid) that it could hold, as opposed to the amount of space the container occupies. Utilizing naturally occurring containers of a comparable shape and subsequently, standardized containers, volume is measured. Arithmetic formulas make it simple to determine the volume of some basic three-dimensional shapes.

We know that

The volume of the cone = area of the base. height/3
