A = 1/2(a+b)h solve for b

Given:

1,5,25,61.....

To find:

The following number.

Solution:

We can see a pattern in the given sequence.

[tex](-1)^2+(0)^2=1+0=1[/tex]

[tex](1)^2+(2)^2=1+4=5[/tex]

[tex](3)^2+(4)^2=9+16=25[/tex]

[tex](5)^2+(6)^2=25+36=61[/tex]

Using this pattern the next term is the sum of squares of 7 and 8.

[tex](7)^2+(8)^2=49+64=113[/tex]

Therefore, the next number is 113.

Let small cups = S

Large cups = L

They bought a total of 8 cups, so S + L = 8

Rewrite as S = 8-L (1st equation)

Then you also have

$3S + $5L = $30 (2nd equation)

Replace the S in the second equation with the first equation:

$3(8-L) + $5L = $30

Simplify:

24 - 3L + 5L = 30

Combine like terms:

24+2L = 30

Subtract 24 from both sides:

2L = 6

Divide both sides by 2:

L = 3

They bought 3 large cups

Since they bought a total of 8 cups, that means they bought 5 small cups ( 8-3=5)

Large = 3 cups, Small = 5 cups

Answer:

she bought 8 coach, 2 first-class

Step-by-step explanation:

let x = number of coach tickets

equation I used:  320x + 960(10 - x) = 4480

                            320x + 9600 - 960x = 4480

                            -640x = -5120

                             x = 8

Answer:

Student's tickets: 60

Adult's tickets: 190

I think this is right

Step-by-step explanation:

"Let x represent the number of tickets sold to students under the age of 16. Let y represent those over the age of 16.

Equation 1, number of tickets sold:

The total number of tickets sold to students under the age of 16 plus the number of tickets sold to students over 16 must equal 250 (since the theater was sold out). The equation becomes:

x + y = 250

Equation 2, revenue from tickets sold.

The total revenue was $910. The cost of tickets under 16 is $2.50 and the cost of tickets over 16 is $4.00. The equation becomes:

2.50 * x + 4.00 * y = 910.00

The system of equations to solve is:

         x  +  y = 250

2.50 * x +  4.00 * y = 910.00 "

Answer:

StartFraction 15 x cubed + 25 x squared + 5 x + 2 Over (5 x squared + 1) squared EndFraction, can be written in mathematical form as

Let y = [tex]\frac{15 x^3 + 25x^2 +5x+2}{({5x^2+1})^2}[/tex]

on  expanding [tex]{({5x^2+1})^2 = 25x^4 +1 + 10x^2[/tex]

⇒ y = [tex]\frac{15 x^3 + 25x^2 +5x+2}{25x^4 +1 + 10x^2}[/tex]  

there correct form of partial fraction is [tex]\frac{15 x^3 + 25x^2 +5x+2}{25x^4 +1 + 10x^2}[/tex]

Relationship: [tex]y =2.92x+4.23[/tex]

They are not proportional

The value is $33.43

Step-by-step explanation:

Given:

[tex]x = years[/tex]

[tex]y = amount[/tex]

When he retired, the expression is:

[tex](x_1,y_1) = (0,4.23)[/tex]

and the rate (m) is:

[tex]m = 2.92[/tex]

Solving (a): The relationship between y and x

This can be solved using the following point-slope formula:

[tex]y - y_1=m(x-x_1)[/tex]

Substitute values for x1, y1 and m

[tex]y - 4.23=2.92(x-0)[/tex]

[tex]y - 4.23=2.92(x)[/tex]

Make y the subject

[tex]y =2.92(x)+4.23[/tex]

[tex]y =2.92x+4.23[/tex]

Solving (b): Are they proportional?

No, they are not

A proportional relationship is expressed as:

[tex]y = mx[/tex]

By comparing this to [tex]y =2.92x+4.23[/tex]; they have different format

Solving (c): Value in 2010?

First, we determine the value of x in 2010

2000; x = 0

2001; x = 1

---

-

2010; x = 10

Substitute 10 for x in [tex]y =2.92x+4.23[/tex]

[tex]y = 2.92*10+4.23[/tex]

[tex]y = 29.2+4.23[/tex]

[tex]y = 33.43[/tex]

Answer:

-4n<-8 the answer for this is (n>2)

n+1<=-3 the answer for this is (n<=-4)

The value of n is less than equal to negative 4 and greater than 2. n ≤ –4 and n > 2.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequalities are given below.

n + 1 ≤ –3  …1

–4n < –8   …2

On solving equation 1, we have

n + 1 ≤ –3

Answer:

Object A will have greater acceleration.

Step-by-step explanation:

Given that,

The mass of object A = 50 kg

The mass of object B = 75 kg

They were pushed with the same amount of force.

We know that, the force acting on an object is given by :

F = ma

Here F is same for both mass

[tex]m_1a_1=m_2a_2[/tex]

Mass and acceleration have inverse relation. It means the object whose mass is less will have greater acceleration. Hence, the acceleration is greater for object A.

Step-by-step explanation:

Answer:

n - 20 ≥ 15

n ≥  35

Step-by-step explanation:

a number could be greater than or equal to 35 and be a solution

Step-by-step explanation:

8. ∠COB and ∠AOD are vertical angles or C

9. Vertical angles are equivalent to each other so 4x-16 = 112°

4x - 16 = 112°

4x - 16 + 16 = 112 + 16

4x = 128

4x/4 = 128/4

x= 32° or D

10. ∠AOC is vertical to ∠DOB therefore the 2 angles are congruent

You can do 360 - (112 + 112) = 2AOC

360 - 224 = 2AOC

136 = 2AOC

AOC = 68°or A

OR

You could just do 180 -112

Since ∠AOD and ∠AOC are supplementary angles, they both add up to 180°

We already know the measure of ∠AOD, it's 112°

So all you would need to do is subtract 112 from 180

And you get 68° or A

Answer:

Bag of lemon

Step-by-step explanation:

Given that:

Cost of loose lemon = $0.99 for 2

Cost of bag of lemon = $2.50 for 6

Calculating the cost per 1 for loose and bag of lemon (unit cost) ;

Loose lemon :

$0.99 /2 = $0.495

Bagged lemon :

$2.50 / 6 = $0.4167

Hence, since the unit cost of bagged lemon is lesser than loose lemon, then purchasing a bag of lemon is better

Answer:

2 teaspoons for the two frozen cookies

3/4 a cup for the cooking oats

2 cups for the flour

Step-by-step explanation:

First Question

The recipe makes 18 cookies. Divide the cookies by 9, half of the batch, to get 2. Now all you have to do is devide the amount of vanilla extract by 9, it will give you two teaspoons.

1 and 1/2 devided by two since you're devidng the recpie by two to get 9 cookies. A cup is four so 3/4 plus 3/4 equals 6/4. Simplified it'd be 1 and 1/2 or 1 and 2/4.

The recipe already calls for 1 and 1/2 a dozen. All you're doing is multiplying the recipe b two to get 3 dozen cookies. Now focusing our attention to the flour, there is 1 cup for 1 and 1/2. Multiply 1 by 2 since there is already half of the recipe here. 1 and 1/2 + 1 and 1/2 is 3 so there'd be 2 cups. Basically just double the recipe.

Answer:

3/4 but if its in decimal form then 0.75

Step-by-step explanation:

Answer:

C. Infinite Solutions

Step-by-step explanation:

In order to solve this we fist have to simplify the equation so we do the following:

[tex]\frac{1}{7}(63n -77) = -11 + 9n\\\\(\frac{1}{7})(7)(63n - 77) = (7)(-11 + 9n) \\\\63n - 77 = -77 + 63n\\63n - 77 = 63n - 77[/tex]

From here we know that any value of n is the solution of this equation so the answer is option C.

Answer:

Slope: -2/7

Step-by-step explanation:

Slope is change in y over change in x.

(4-6)/(10-3)

= -2/7

Answer/Step-by-step explanation:

Given two points on a line, (-4, 10) and (0, 2), the slope of the line is calculated as follows:

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Let,

[tex] (-4, 10) = (x_1, y_1) [/tex]

[tex] (0, 2) = (x_2, y_2) [/tex]

Plug in the values

[tex] slope (m) = \frac{2 - 10}{0 - (-4)} [/tex]

[tex] slope (m) = \frac{-8}{4} = -2 [/tex]

Slope = -2

The wrong formula was used. Slope is supposed to be change in y over change in x. Rather the difference of each coordinates was solved and divided by each other, which makes the whole calculation wrong.
