Josh and Raheem both invest some money.
Josh invests £1200 at Banks’R’us, who pay 4% simple interest per year.
Raheem invests £1250 at Bank World who pay 3% compound interest per year.
They invest the money for 5 years.
Who has the most money in their account after 5 years?

;v;

Answers

Answer:

Raheem

Step-by-step explanation:

Josh :

using simple interest formula :

Final amount = P(1 + rt)

Final amount = 1200(1 + 0.04*5)

Final amount = 1200(1.2)

Final amount = £1440

Raheem :

Using compound interest formula :

Final amount = P(1 + r/n)^nt

Final amount = 1250(1 + 0.03)^5

Final amount = 1250(1.03)^5

Final amount = £1449.09

Noah and Lin are marketing paper cones to hold popcorn to hand out at parent math night. They want the cones to hold 9 cubic inches of popcorn. What are two different possible values for height h and radius r for the cones?


if h=3, then r=


if r=2, then h=

Answers

Answer: r = 1.69 inches

              h = 2.15 inches

Step-by-step explanation: Volume of a solid is the amount of space contained within a solid.

Volume of a cone is directly proportional to radius and height:

[tex]V=\frac{1}{3}\pi r^{2}h[/tex]

They want the cones to hold the same volume of 9 cubic inches.

If height is 3:

[tex]9=\frac{1}{3}\pi r^{2}3[/tex]

[tex]\pi r^{2}=9[/tex]

[tex]r^{2}=2.864[/tex]

r = 1.69 inches

When height is 3, radius is 1.69 inches for a cone to have 9 cubic inches of volume.

If radius is 2:

[tex]9=\frac{1}{3}\pi (2)^{2}h[/tex]

[tex]h=\frac{9(3)}{4 \pi}[/tex]

h = 2.15 inches

If radius is 2 inches, height of the cone is 2.15 inches.

Three numbers A, B and C are in the ratio 7: 2: 4. The sum of the three numbers is 104. What is the number C?

Answers

Answer:

C = 32

Step-by-step explanation:

The numbers are in the ratio 7 : 2 : 4 = 7x : 2x : 4x ( x is a multiplier ) , then

7x + 2x + 4x = 104

13x = 104 ( divide both sides by 13 )

x = 8

Thus C = 4x = 4 × 8 = 32

The correct equation for the triangle is,

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

By the figure, the coordinate of triangles are,

D = (- 5, 1)

E = (- 2, 3)

F = (- 3, - 2)

Hence, By using distance formula;

DE = √ (- 5 + 2)² + (1 - 3)²

     = √9 + 4

     = √13

EF = √ (- 2 + 3)² + (3 + 2)²

     = √1 + 25

     = √26

FD = √ (- 5 + 3)² + (1 + 2)²

     = √4 + 9

     = √13

Thus, We have;

⇒ DF ≅ FD

the keyword is “increased”. That shows that you need to add instead of multiply. “a” is the secret number. Think of it like a sandwich... the bread is a (the secret number) and the meat is + (increased by) and the other bread is the 7. Hope this helps!:)

Consecutive numbers follow one right after the other. An example of three consecutive numbers is 17, 18, and 19. Another example is -100, -99, -98. How many sets of two or more consecutive positive integers can be added to obtain a sum of 100? What are they?
help pls

Answers

I would say none because if you try to find numbers that add up to 100 you won’t find them as integers. The answer is either no sets at all or you can do numbers that are consecutive like 32 1/3 , 33 1/3 and 34 1/3 . They all add up to 100 but I’m not sure cause they’re not full numbers so they’re not integers.

The solution is 32 1/3 , 33 1/3 and 34 1/3

The three consecutive numbers which have a sum of 100 is given by the equation A = 32 1/3 + 33 1/3 + 34 1/3

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the first number be = n

Let the second number be = n + 1

Let the third number be = n + 2

So , the sum of all the three consecutive numbers is 100

Substituting the values in the equation , we get

n + ( n + 1 ) + ( n + 2 ) = 100   be equation (1)

On simplifying the equation , we get

3n + 3 = 100

Subtracting 3 on both sides of the equation , we get

3n = 97

Divide by 3 on both sides of the equation , we get

n = 32 1/3

So , the first number n = 32 1/3

Second number = n + 1 = 33 1/3

Third number = n + 2 = 34 1/3

Therefore , A = 32 1/3 + 33 1/3 + 34 1/3 = 100

Hence , The three consecutive numbers which have a sum of 100 is given by the equation A = 32 1/3 + 33 1/3 + 34 1/3

Step-by-step explanation:

y= -3x + 1 and y= x - 3

Answers

Answer:

x= 1

y= -2

Step-by-step explanation:

equation (1): y= -3x+1

equation (2): y=x-3

solve the system of equations by substitution:

step1: sub ( x-3 ) for y in equation 1:

y = -3x+1

x-3 = -3x+1

step2: simplify the equation to get x:

(add 3 for both sides)

x = -3x+4

(add 3x for both sides)

4x = 4

(divide 4 from both sides)

x = 1

step3: sub the value of x (x=1) in equation 2:

y = x-3

y = 1-3

step4: solve the equation to get y:

y = -2

PLS HELP WILL GIVE BRAINLIEST!! Identify this set of lines as parallel, perpendicular, or neither.

Answer:

neither

Step-by-step explanation:

Answer:

neither

Step-by-step explanation:

parallel lines have the same slope

perpendicular lines have the opposite of the reciprocal of the slope of the other line

The slope of the first line is 3 and the slope of the second line is -3.

If the lines were parallel, the slopes would be the same, so 3 = -3 which is not true, so they aren't parallel.

If the lines were perpendicular, the slope of the second line would be the opposite reciprocal of 3, or -1/3. -1/3 does not equal 3, so these lines are not perpendicular

Ashleigh wants to double her money. She put $5,000 in a bank account that pays 4% compounded continuously. How long will it take her to double her money? (Round to

Answers

Answer:

approximately 17.3 years

Step-by-step explanation:

Compound interest is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

The formula used to find continuously compounded is:

t = log (A/P) / r

The time it will take to double her money is 17.329 years.

What is compound interest?

It is the interest we earned on the interest.

The formula for the amount earned with compound interest after n years is given as:

A = P [tex](1 + r/n)^{nt}[/tex]

P = principal

R = rate

t = time in years

n = number of times compounded in a year.

We have,

P = $5,000

r = 4%

Amount = 2 x 5000 = $10,000

n = infinite number of times.

Now,

Solve the equation for t

The formula used to find for continuously compounded is:

t = log (A/P) / r

t = log (10,000.00/5,000.00) / 0.04

t = 17.329 years

Thus,

The time it will take to double her money is 17.329 years.

Answers

Responder:

(x + 2) ² + (y-4) ² = 100

Explicación paso a paso:

La ecuación de un círculo se expresa como (x-x0) ² + (y-y0) ² = r²

r es el radio

(x0, y0) es el centro

Dado que el centro representa el punto medio de (-7, -6) y (3,14)

x0 = -7 + 3/2

x0 = -4/2

x0 = -2

y0 = -6 + 14/2

y0 = 8/2

y0 = 4

Sustituir en la expresión

(x - (- 2)) ² + (y-4) ² = 10²

(x + 2) ² + (y-4) ² = 100

Por lo tanto, la ecuación requerida del círculo es (x + 2) ² + (y-4) ² = 100
