SOMEONE PLEASE HELP!
5.) Write both an explicit equation and a recursive equation for the sequence 4, 2, 1,05,0.25...

Explicit equation:


Recursive equation:


HURRY PLEASE!!!​

Answer:

Step-by-step explanation:

2/5

Answer:

x-7

x + 2

Step-by-step explanation:

the equation is a quadratic equation

we need to find factors of -14x² that would add up to -5x

these factors are -7x + 2x

(x² + 2x) - (7x - 14)

factorise the expressions in the bracket

x(x + 2) -7(x + 2)

(x-7 )

or x + 2

Answer:

28¢

Step-by-step explanation:

A quarter is 25¢, so 53¢ - 25¢ = 28¢.

Answer:

x²+y²=225

Step-by-step explanation:

when centered at the origin the equation of a circle is x²+y²=r²

we are given x and y so 9²+12²=r²

[tex]r^{2} =9^{2} +12^{2}\\ =81+144\\ =225[/tex]

Answer:

Answer:

170

Step-by-step explanation:

Answer:

1160

Step-by-step explanation:

1000×4/100% ×4=160

add the1000+160 since they have asked altogether=1160/=

Answer:

the area of the actual floor is  784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant

Step-by-step explanation:

The computation of the area and the ratio of the area is shown below:

The ratio of the drawing area to the actual area is  

= ((1 cm) ÷ (4 ft))²

= (1 cm²) ÷ (16 ft²)

 Now the actual floor area is  

(16 ft²) ÷ (1 cm²) = actual area ÷ (49 cm²)

= (16 ft²) × 49 ÷ 1

= 784 ft²

hence, the area of the actual floor is  784 ft² and the ratio is (1 cm²) ÷ (16 ft²). The same would be relevant

Answer:

Set this up as a proportion.

54/n = 75/100

Now solve for n and finish from here.

Can i also have brain or a heart :)

Answer:

x would equal 72

Step-by-step explanation:

you can find a percent but there is already a percent showing. So the answer should be 72.

When you're trying to find the answer to these problems you should check if there is a percent part and whole. In this question, there is already a percent and a part so you would just try to find the whole.

Answer: 32

Step-by-step explanation:

5+3*(5-2)^2

5+3*(3)^2

5+3*9

5+27

32

Answer:

32

Step-by-step explanation:

5 + 3 * (5 - 2)^2

5 + 3 * 3^2

5 + 3 * 9

5 + 2

= 32

Answer:

The answer is 40

Step-by-step explanation:

8+3+5+4=20

Once you added all the nunbers mutilpy by 2

20x2=40

that's how you get 40 as your answer

hope that helps ❤

Answer:

1. 63

3. 117

4.

Step-by-step explanation:

gimme some time to do 2 and 4

Answer:

x = 1, y = 46

Step-by-step explanation:

Since the triangles are congruent then corresponding sides and angles are congruent, then

DE = AB , that is

3x + 6 = 9 ( subtract 6 from both sides )

3x = 3 ( divide both sides by 3 )

x = 1

and

∠ C = ∠ F

10x + y = 56 ( substitute x = 1 )

10(1) + y = 56

10 + y = 56 ( subtract 10 from both sides )

y = 46

Answer:

8

Step-by-step explanation:

it's 8 because parallel lines have equal slopes

Answer:

42%

Step-by-step explanation:

The computation of the percentage is shown below:

Here we assume that there are 100 students

So according to the question

60% of the students would pack the lunch i.e. 60 students

And, 40% of the students buy a lunch i.e. 40 students

Now the students who pack the lunch they have 70% of cookie

So, 70% of 60 students = 42 students

Now the percentage is

= 42 students ÷ 100 students

= 42%

Answer:

58.75

Step-by-step explanation:

You add all the numbers and get 470 then divide it by the amount of numbers there which is 8 so 470 divided by 8 is 58.75

V = 4/3 × 3 × 5^3

V = 4 × 125

V = 500 cm^3

Answer:

-6

Step-by-step explanation:

I'm not really sure whether or not your question is asking for the slope intercept form or just the slope.

Your answer would be: y = -6x + 7   [if your question is asking for the slope intercept form]

OR

Your answer would be: -6   [if your question is asking for just the slope]

Answer:

30

Step-by-step explanation:

if he can make 42 cakes = 7days

therefore x cakes. =5days

you do cross multiplication

i.e. 42x5/7 =30 days

Answer:

B

Step-by-step explanation:

We have to find which trinomial has:

1) two terms that are the perfect square of two numbers

2) a terms that is the double product of the two numbers

the first condition is satisfied by A and B, but only B satisfied the second., in fact the trinomial can be rewrite as: (2a-5)^2

Options C and D are traps because the square of a number can’t be negative

Answer:

b ≤ 12

Step-by-step explanation:

The area of the rectangle is given by length multiplied by breadth.

The area of the rectangle up to 48 units square means that it can be 48 or less than 48.

If the height given is taken as the width of the rectangle then we can find the base which will be the length of the rectangle.

Area = length * breadth

4units * base ≤ 48 units square

base ≤ 48 units square/4 units

base ≤ 12 units

b ≤ 12 units
