To find out how many weeks Tameca needs to save to have at least $100, we create an inequality, 5w + 55 >= 100, where 'w' represents the number of weeks. Solving this inequality gives w >= 9. Therefore, Tameca needs to save for at least 9 weeks.

The subject of this problem is linear inequalities, which falls under Mathematics. To solve this problem, let's denote the number of weeks that Tameca needs to save money as 'w'. Since she already has $55 and is saving $5 each week, the inequality that represents this situation is 55 + 5w >= 100.

In order to solve this inequality, we need to isolate 'w'. You can do this by subtracting 55 from both sides of the inequality to get 5w >= 45. Then, divide both sides by 5 to get w >= 9.

Therefore, Tameca must save for at least 9 weeks in order to have a minimum of $100 in her savings account.

We need to find x or the adjacent

We are given the Opposite ( 10 )

We don't need the hypotenuse

So we use our formula triangles

TOA             SOH                  CAH

Since we don't need the hypotenuse, we look for a formula without ' H ' in it and it is TOA so we use it

Tan = Opposite ÷ Adjacent

We need to find the adjacent so we rearrange the formula into

Adjacent = Opposite ÷ Tan

Adjacent = 10 ÷ tan(25)

Adjacent = 21.44506921

We are asked to simplify the given polynomial expression in terms of the variable x.

The algebraic expression is given as:

[tex](-9x^2+2x+13)-(-7x^2+3x+6)[/tex]

On taking out the terms from both the brackets the sign of the terms of the second bracket gets interchanged as there is a negative sign preceding it.

Hence, we get the expression as:

           [tex]=-9x^2+2x+13+7x^2-3x-6\\[/tex]

Now on combining the like terms we get:

       [tex]=-9x^2+7x^2+2x-3x+13-6\\\\\\=-2x^2-x+7[/tex]

To solve this all you need to do is take the fraction 2/5 and multiply it by a number (this means you multiply BOTH the denominator and the numerator)

1. Multiply the original fraction by 2:

[tex]\frac{2*2}{5*2} = \frac{4}{10}[/tex]

2. Multiply the original fraction by 3:

[tex]\frac{2*3}{5*3} = \frac{6}{15}[/tex]

3. Multiply the original fraction by 4:

The current value of a future sum of money. The Present Value allows us to calculate what is the value of today that has an amount of money that we will not receive right now but later, in the future.

Present value seeks to reflect that it is always better to have an amount of money today than to receive it in the future. In fact, if we have the money today we can do something to make it productive, such as investing in a company, buying shares or leaving it in the bank that pays us interest, among other options. In addition, even if we do not have a certain plan to invest the money we can simply spend it to satisfy our tastes and we do not have to wait to receive the money in the future.

Hello There! Your answer is D) about 54%.

To find your answer, start by adding together all of the totals for each gender.

Female: 119 + 150 + 447 + 735 + 1174 = 2625

Male: 103 + 171 + 512 + 710 + 756 = 2252

Total: 2625 + 2252 = 4877

The question is asking what percentage of the respondents was female. So, we are finding what precent of 4877 is equal to 2625. To do this, divide 2625 by 4877 and multiply what you get by 100.

2625 divided by 4877 =  0.53824072175 x 100 = 53.824072175%.

Out of the answer choices provided, D) about 54% is correct since 53.824072175% is very close to 54%.

Answer:

8 ft

Step-by-step explanation:

let width = x

then length= x+2

Area = l(w)

        =x(x+2)

168  = x^2 + 2x

x^2 + 2x-168=0

Using quadratic formula we get roots :

x= 12, x=-14

x= 12 (as width cannot be in negative)

then length= x+2 = 14

length of rug= length of floor - 4

                     = 14- 4

                    = 10

width of rug= width of floor- 4

                    = 12-4

                    = 8

Hence the length (the shorter side) of the rug be 8 feet !

Answer:

$13,997.53

Step-by-step explanation:

The simplest, minimally acceptable answer would stem from multiplying by 5 the $247.43 monthly payment and subtracting the result from the amount initially owed:

$15,234.68

-$ 1,237.15

----------------

$13,997.53

To calculate the net change to the loan from Quiana's perspective over the past 5 months, subtract the total amount she has repaid from the initial loan amount. In this case, the net change is $13,997.53.

The amount owed to the lender = $15,234.68

Amount repaid = $247.43

Time = 5 months

To calculate the net change to the loan from Quiana's perspective over the past 5 months, we need to subtract the total amount she has repaid from the initial loan amount.

Since she repaid $247.43 each month for 5 months, the total amount repaid is $247.43 x 5 = $1237.15.

To find the net change to the loan, we subtract the total amount repaid from the initial loan amount:

= $15,234.68 - $1237.15

= $13,997.53.

Answer:

Approximately 53

Step-by-step explanation:

This is a geometric progression, because each term is found by multiplying the previous one by a constant factor.

In our case, the first term is know (a1 = 3), and the growth factor is also known (q = 1.333333).

What we are tasked to do is to find the 11th (n=11) term of the series, since it asks for AFTER the 10th roll..  That's easy with the base formula:

[tex]a_{n} = a_{1} q^{n-1}[/tex]

Let's place the values we have in the equation and solve it:

[tex]a_{10} = 3 * (1.333333)^{11-1} = 3 * (17.758) = 53.3[/tex]

So, after the 10th roll, you should need 53 dice, approximately.

Answer:

24 in²

Step-by-step explanation:

The easy way:

The two legs, or shorter sides, of a right triangle form that triangle's base and height. Knowing that the area of a triangle is [tex]\frac{bh}{2}[/tex] (where b is the base and h is the height), we can use the 6 inch leg for the base and the 8 inch leg for the height to find an area of [tex]\frac{6(8)}{2}=\frac{48}{2}=24[/tex] in².

The harder but more general way

There's a nice formula for calculating the area of any triangle given its side lengths found by this Greek guy named Heron, and it's appropriately called Heron's formula:

[tex]A=\sqrt{s(s-a)(s-b)(s-c)[/tex]

a, b, and c are the lengths of triangle, and s here is half the triangle's perimeter (also called the semi-perimeter), or mathematically:

[tex]s=\frac{a+b+c}{2}[/tex]

For our problem, let's pick a = 6, b = 8, and c = 10. This would give us

[tex]s=\frac{6+8+10}{2} =\frac{24}{2}=12[/tex]

Substituting that s back into Heron's formula, we get

[tex]A=\sqrt{12(12-6)(12-8)(12-10)}=\sqrt{12(6)(4)(2)}\\=\sqrt{72(8)}=\sqrt{576}=24[/tex]

So our area is 24 in²

Step-by-step explanation:

It is computed that loan Q's finance charge will be $83.73 greater than loan P's.

From the information, the payment for bank P will be:

= (0.058/12)(19450) / [1 - (1 + 0.058/12)^108

= 231.59

The future value will be:

= 231.59 × 12 × 9

= 25011.72

The finance charge for P will be:

= (25011.72 - 19450) + 925

= 6846.72

The payment for Q is 211.08. The future value will be:

= 211.08 × 12 × 10

= 25329.60

The finance charge for Q will be:

= (25329.60 - 19450) + 690.85

= 6570.45.

The difference will now be:

= 6570.45 - 6846.72

= $83.73

Answer: Sasha has 20 bars to start of with. Let's assume Sasha keeps 6 bars for herself. The problem says Sasha has twice as many bars as Hanna, so Hanna HAS to have 3 bars. The problem says Kyle got 3 more bars than Hanna, so 3+3=6, and Hannah got 2 less bars than Noah.. Noah has to have bars because 5-3=2

Sasha 6, Kyle 6, Noah 5, Hanna 3= 6+6+5+3=20

Step-by-step explanation:

Final answer:

Using equations based on the relationship between the number of muesli bars each person has, we determine that Sasha ended up with 6 muesli bars.

Explanation:

The subject of this question is mathematics, specifically it involves solving a word problem by setting up equations based on the given relationships among the quantities. Let's find out how many muesli bars Sasha had in the end.

Let's denote the number of muesli bars Sasha, Hannah, Noah, and Kyle have as S, H, N, and K respectively. The problem gives us the following relationships:

H = N - 2 (Hannah has two fewer bars than Noah)

K = H + 3 (Kyle has three more bars than Hannah)

S = 2H (Sasha has twice as many bars as Hannah)

Since there are 20 muesli bars in total, we can write the equation:

S + H + N + K = 20

Substituting the relationships into the equation we get:

2H + H + (H + 2) + (H + 3) = 20

Combining like terms, we have:

5H + 5 = 20

Subtracting 5 from both sides, we get:

5H = 15

Dividing both sides by 5, we find H:

H = 3

Now, we can find S:

S = 2H = 2(3) = 6

So, Sasha had 6 muesli bars in the end.

Let, that number = x

It would be: x * 0.65 = 52

x = 52 / 0.65

x = 80

So, that number and your answer is 80

18 is 45% of 40

Well, just looking at this problem we know 3 formulas that will help us. Firstly we have C (The Circumference) is Equal to 2π Times the Radius, r.

In Equation form that looks something like this:

C=2πr

We also know that the radius is half of the diameter, r=D/2  or D=2r

So, if C=62.8, then 62.8=2πr must also be true.

By doing some quick re arranging we get to the equation r=62.8/2π

This equation gives us 9.99, Which is essentially 10.

Now that we know that r=10, we can find that diameter, D=2r, is Equal to 20.

Therefore, your answers are

Radius = 10

Diameter = 20

Circumference = 62.8 (Given)
