Step-by-step explanation:

If you have a normal ginger bread cookie, its full size would be 100%. So, if you add the first 25%, 1.25%

The expression best describes the new length of the cookie will be 1.25y.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

Given that:-

The initial length of the cookie is y after baking the length is increased by 25%

=   y  +  25%y

=   y   +  ( 25 / 100 ) y

=   y  +  0.25 y

=  1.25 y

Therefore the expression best describes the new length of the cookie will be 1.25y.

Answer:

In 6 years form now, the balance in Gordon's account will be = {$1,200 x [1 + (2.5% x 6 years)]} = $1,380

his account will have earned = 2.5% x 6 years x $1,200 = $180 in interests over the six years

In 6 years form now, the balance in Bailey's account will be = $900 x (1 + 3.25%)⁶ = $1,090.39

his account will have earned = $190.39 in interests over the six years

Bailey's account earned more interest than Gordon's, even though his initial balance was much lower. This was due to higher interest rates and more important, because Bailey earned compound interest.

If I wanted to safely climb a 50 foot wall, I would use a 51 foot ladder.

Step-by-step explanation:

If I wanted to climb a fifty foot (50 ft) wall, I would use a fifty one foot (51 ft) ladder because the safe way to position a ladder against the wall requires that I leave one foot (1 ft) distance from the base of the ladder to the wall. That way, the ladder won't be too close nor too far from the wall.

Answer:

x > 7

Step-by-step explanation:

-3 < x - 10

Subtract x from both sides.

-x - 3 < -10

Add 3 to both sides.

-x < -7

Divide both sides by -1. Remember that when you multiply or divide both sides of an inequality by a negative number, the inequality sign changes direction.

x > 7

Answer:

(x-9)(x-3)

Step-by-step explanation:

Look to the number on the right, 27, and list out the factors. (1 and 27, 3 and 9, -1 and -27, -3 and -9)

Next, find the factors that would equal the middle number, -12, when added. -3 and -9 add to -12. Therefore, choose these numbers and put them in the form (x-9)(x-3).

Answer:

As an improper fraction: [tex]15/11[/tex]

As a mixed number: [tex]1 \frac{4}{11}[/tex]

As a decimal: 1.36

Step-by-step explanation:

[tex]3/5x - 1/3x = x - 1[/tex]

Find a common denominator between 5 and 3 (15)

[tex](3 * 3) / 15x - (1 * 5) / 15 = x - 1[/tex]

[tex]9/15x - 5/15 = x - 1[/tex]

Subtract the fractions

[tex]4/15x = x - 1[/tex]

Subtract x from both sides of the equation

[tex]-11/15x = -1[/tex]

Multiply both sides of the equation by 15/-11 to simplify

x = 15/11

Hope this helps :)

Answer:

Exact Form:

x  =  15/11

Decimal Form:

x  =  1.36

Mixed Number Form:

x  =   1(4)/(11)

Step-by-step explanation:

(3)/(5)x-(1)/(3)=x-1

Simplify  (3)/(5)x-(1)/(3)x

(4x)/(15)=x-1

Move all terms containing  x  to the left side of the equation.

-(11x)/(15)=-1

Multiply both sides of the equation by    -(15)/(11)

-(15)/(11)(-(11)/(15))= -(15)/(11) . -1

Simplify both sides of the equation.

(15)/(11)

The result can be shown in multiple forms.

Step-by-step explanation:

y = 10x - 32

To find the x intercept set y =0 and solve for x

0 = 10x -32

Add 32 to each side

32 = 10x

Divide by 10

32/10=10x/10

3.2 = x

To find the y intercept set x =0 and solve for t

y = 10*0 -32

y= -32

Answer:

y.(0,-32)

x.(3.2,0)

Answer:

The width of the tank is approximately 7.9 feet.

Step-by-step explanation:

The pool is a rectangular prism with the following dimensions:

length = 2*x feet

width = x feet

height = 4 feet

With volume equal to 500 cubic feet, therefore:

volume = length*width*height = 500

(2*x)*(x)*(4) = 500

8*x² = 500

x = sqrt(500 / 8)

x = sqrt(62.5)

x = 7.90569 feet

The width of the tank is 7.9 feet.

Answer:

6 ways

Step-by-step explanation:

The total number of people we have entering Kennywood is 6, since it’s Jim with 5 of his friends.

Now, we can only have movement through the game one at a time

The number of ways they can move through the gate one at a time is 6C1 ways

and that is mathematically;

if we are to select a number of r items from a total of n, the number of combinations or ways is;

nCr = n!/(n-r)!r!

Applying these to the problem at hand, we have

6!/(6-1)!1! = 6!/(5!)(1!) = (6 * 5!)/5! = 6 ways

By Probability, 0.25 is simulation could you use to answer questions about whether a surfer will see a dolphin.

What does a probability simple definition entail?

A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%. Probability is a measure of how likely or likely-possible something is to happen.

                                         For instance, the chance of flipping a coin and obtaining heads is 1 in 2, as there is only one method to acquire a head and there are a total of 2 potential outcomes (a head or tail). P(heads) = 12 is the formula.

the beach lifeguards, there is a 25% chance.

Answer:

x=((log(81))/(log(3))+2)/3

Step-by-step explanation:

so what you want to do is get 3x-2 out of the exponent

you can do that by using log

so apply log to both sides and you get

log(81)=(3x-2)log(3)

the 3x-2 is moved in front of the log due to a log rule

then (log(81))/(log(3))=3x-2

(log(81))/(log(3))+2=3x

((log(81))/(log(3))+2)/3=x

then use a calculator to find the exact value

Part A. Yes, these ratios forms a proportion

Part B-  the ratio of the number of friends in Case 1 to the number of friends in Case 2 is 5:1

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The ratios in cases 1 and 2 form a proportion. IT can be seen by dividing case a by 5 which gives 4:3;

i.e 20:15

If we divide both numerator and denominator by 5, then we have 4/3.

This shows case 1 and 2 have the same proportions of friends to strangers.

Part B; The number of friends in case 1 is 20 while in case 2 is 4.

we have, 20:4

= 20  4

Dividing each by 4, we have 5:1.

Which means that the ratio of friends that in case 1 to case 2 is 5:1.

Answer:

For this case Mr Doyle nees to cut his rectangular lawn and we assume that all the place is covered by lawn so then we need to find the area.

[tex]A = 23ft* 25 ft = 575 ft^2[/tex]

So then Mr Doyle need to mow 575 ft^2 in order to finish the job

Step-by-step explanation:

For this case Mr Doyle nees to cut his rectangular lawn and we assume that all the place is covered by lawn so then we need to find the area.

And the area for a rectangular shape is given by:

[tex] A = lw[/tex]

Where l is the length and w the width. If we replace the info given we got:

[tex]A = 23ft* 25 ft = 575 ft^2[/tex]

So then Mr Doyle need to mow 575 ft^2 in order to finish the job

Answer:

[tex]A = 23ft\times25 ft \\\\= 575 ft^2[/tex]

Mr Doyle need to mow [tex]575 ft^2[/tex] in order to mow the entire lawn

Step-by-step explanation:

Mr. Doyle needs to mow his rectangular lawn that measures 23 x 25 square feet.

we will have to find the area.

And the area for a rectangular lawn is Length * Breadth

A = L * B

Where l is the length and B is the width.

L = 23 square feet

B = 25 square feet

By inputting the values we get,

[tex]A = 23ft\times25 ft \\\\= 575 ft^2[/tex]

Therefore, Mr Doyle need to mow [tex]575 ft^2[/tex] in order to mow the entire lawn

Answer:

Givens

[tex]DR=PT=3cm[/tex] and [tex]RP=4cm[/tex]

Points D, R, P and T are collinear.

The image attached shows a representation of this problem.

By sum of segments, we have

[tex]DT=DR+RP+PT[/tex]

Replacing all given values, we have

[tex]DT=3+4+3=10 \ cm[/tex]

Therefore, the segment DT is 10 centimeters long.

Now, we know that point E is the center of segment RP, which means is a middle point, divides the segment equally. So, to prove that segment DT is symmetrical regarding point E, we need to prove that both sides are equal.

[tex]RE=EP=2cm[/tex], by definition of middle point.

By sum of segments, we have

[tex]DR+RE=3+2=5cm\\EP+PT=5cm[/tex]

Which means [tex]DR+RE=\frac{DT}{2}\\ EP+PT=\frac{DT}{2}[/tex].

Therefore, segment DT is symmetrical regarding point E.
