find the nth term formula in the sequence - 1,9,21,47,57

Answer:

39

Step-by-step explanation:

Draw a line from V to R. That gives you a triangle MVR

The height of the triangle = 3

The base of the triangle = 6

Area Triangle =                           1/2 * 3 * 6 =   9

The figure left over is a rectangle

Area = VR * VE

VR = 6

VE = 5

Area = 6*5 =                                                  30

Total area =                                                   39

Answer:

We can split this figure into two shapes;

A triangle, and a rectangle.

If we split the figure from 'V' to 'R', it will formulate the two shapes I mentioned.

First, we must know the formula for the area of a triangle -

A = BH x 1/2

Where B represents the base, and H serves as the height.

For the triangle, the height is 3, and the base is 6.

So we plug in these values into our formula:

A = BH

A = 6(3) x 1/2

A = 18 x 1/2

A = 18/2

A = 9

Now the formula for the area of a rectangle:

A = LW

Where L displays as the length, and W illustrates the width.

Our width of the following rectangle is 6, while our length is 5.

Plug in our values into the formula:

A = LW

A = 5(6)

A = 30

Now, we add our areas;

9 + 30 = 39 square units, is our answer.

Answer:

136 [tex]m^{2}[/tex]

Step-by-step explanation:

Well if you find the lateral area (the area of the rectangles on the sides) to get 112, so you just need to add that to the triangles and for those (they add up to 36) you can just use the formula for the area of a triangle,  which is [tex]b*h/2[/tex].

Answer:

[tex]\frac{-2}{3}[/tex]

Step-by-step explanation:

First, change the mixed numbers to improper fractions to make the solving process easier.

1 2/3 = 5/3

2 1/3 = 7/3

Now, subtract.

5/3 - 7/3 = -2/3

Answer: -2/3

Answer:

M=17

S=9

Step-by-step explanation:

m = 17 and s = 9

Refer to the attachment for full solution . The main key here is to multiply first equation by 3 so that in both equations the coefficient of m will be same so that we can eliminate 3m and then we will solve for s and then putting value of s in any of the equation , so we can get m

Note :- You can multiply the 1st equation by 8 too for making coefficient of s same and then solving for m and then solving for s

Answer:

4 pies

Step-by-step explanation:

Hello!

We know that 12 apple pies are 75 percent of the total apple pies.

Let x = # of pies total.

This means that 75% of x, or 0.75x is 12

Solve:

Now, 16 is the total number of pies. To find the number thrown out, we subtract 12.

16 - 12 = 4

4 pies were thrown out

Solution:

Let "a" represent total apple pies.

Note that:

Simplify the LHS:

Use cross multiplication:

Divide 75 both sides:

If there were 16 apples and 12 were sold, 4 apple pies were thrown out.

Hello.

A composite number has more than 2 factors; it's divisible by 1, itself, and something else.

Let's find the composite numbers smaller than 18.

The composite numbers are

4, 6, 8, 9, 10, 12, 14, 15, 16.

4x3

Step-by-step explanation:

The total price in dollars and cents is twenty dollars and sixty cents.

Discount rates are the reduction of actual price knowns as a benefit that a customer or a consumer enjoys in the total amount of goods or products being purchased. They are calculated by multiplying the total amount of goods bought with the discount percentage rate given.

From the given information:

Thus, before tax deduction, the total of items bought while taking the discount rate into consideration is:

= 16% × $24.50

[tex]\mathbf{= \dfrac{16}{100} \times \$24.50}[/tex]

= $3.92

The total price after removing the discount price now will be:

= $24.50 - $3.92

= $20.58

≅ $20.60   (to the nearest cent)

Answer:168.75 squared

Step-by-step explanation: we know that the whole of the rectangle ( including the outline) is 225 cm squared

so half of this is 225 divide by 2 and that is 112.5

but we also have a right-angled triangle that is half the half rectangle so we do 112.5 divide by 2 and that is 56.25

to finish it off we ad 56.25 with 112.5 and that is 168.75

Answer:

180mm²

Step-by-step explanation:

Area of rectangle = 15mm x 9mm

                             = 135mm²

EF = 15mm - 9mm = 6mm

Area of triangle = [tex]\frac{1}{2}[/tex] x 6mm x 15mm

                          = 45mm²

Total area = 135mm² + 45mm²

                 =180mm²      

The equation computed simply shows that the number of months will be C. 9 months.

From the information given, the equation 8m+3=75 models how many months, m, it takes a tree to reach a height of 75 inches after being potted.

Therefore, the number of months will be calculated thus:

8m + 3 = 75

8m = 75 - 3

8m = 72

m = 72/8

m = 9

The correct option is 9 months.

Step-by-step explanation:

First, we're looking to find the number of stamps that AREN'T foreign, so we have to subtract 68% from 100%.

Now, we know that 32% of the stamps are NOT foreign. So, next, we:

Therefore, the answer is 72 stamps.

Let us consider a quadratic equation αx² + βx + c = 0, then nature of roots of quadratic equation depends upon Discriminant (D) of the quadratic equation.
