what point represents the opposite of 1 1/3

Answer:

Let's assume Karl rents the bike for x hours. Then the cost of renting the bike can be expressed as:

Cost = 7x + 9.5

We know that the maximum cost Karl can afford is $55. So we can set up an equation:

7x + 9.5 ≤ 55

Subtracting 9.5 from both sides:

7x ≤ 45.5

Dividing both sides by 7:

x ≤ 6.5

Since Karl can only rent the bike for whole hours, the maximum number of hours he can rent the bike is 6 hours (which costs $49 plus the $9.5 flat fee, for a total of $58.5). If he rented it for 7 hours, it would cost $60.5, which is over his budget.

Homer would have taken approximately 8.11 hours to do the job by himself.

Let h be the time it would take Homer to do the job by himself, and let m be the time it would take Mike to do the job by himself. We know from the problem that:

m = h - 1 (Mike can do the job one hour quicker than Homer)

We also know that they worked together for 4 hours, so they completed 4/h + 4/m of the job. We can set up an equation based on this:

4/h + 4/m = 1 (they completed the entire job)

Substituting m = h - 1, we get:

4/h + 4/(h-1) = 1

Multiplying both sides by h(h-1), we get:

4(h-1) + 4h = h(h-1)

Simplifying:

8h - 4 =

[tex]h^2 - h[/tex]

Rearranging:

[tex]h^2 - 9h + 4 = 0[/tex]

Using the quadratic formula, we get:

[tex]h = (9 ± \sqrt{(9^2 - 414)) / 2} [/tex]

Since we are looking for a positive value of h, we take the positive square root:

h ≈ 8.11

Answer: 3690

Step-by-step explanation: i think

The total amount in the account after 5 years is $3690.

Simple interest is the borrowing amount added only to the principal amount.

The Formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100,

Where S.I. is simple interest, P is the principal amount, T is the time period and R is the interest rate in a year.

In this case, the principal is $3600, the rate is 0.5% (or 0.005 as a decimal), and the time is 5 years.

Plugging these values into the formula, we get:

Interest = $3600 x 0.005 x 5 = $90

So after 5 years, the interest earned on the account is $90. To find the total amount in the account, we need to add the interest to the principal:

Total amount = Principal + Interest = $3600 + $90 = $3690

Therefore, the total amount in the account after 5 years is $3690.

Answer:  Nate have 278 cookies now.

Step-by-step explanation:

the original amount of cookies for Nate is 300, and he dropped 145, which means we need to subtract 145 from 300.  And his mom brought him 123 more, which means we need to add 123.

300 - 145 + 123 = 278

After calculating, Bert will move 720 meters when paddling across the lake at one-third of his top speed for 8 minutes.

Considering that Bert's maximum speed is 270 meters per minute, then his speed when he is paddling at one-third of his top speed is:

270 m/min * (1/3) = 90 m/min

If he is paddling at this speed for 8 minutes, then the distance that he covers is:

distance = speed * time = 90 m/min * 8 min = 720 meters

Step-by-step explanation:

The sum of 10 3/4 and 12 1/4 is 23.

To add the mixed numbers 10 3/4 and 12 1/4, follow these steps:

Step 1: Add the whole number of parts.

Add the whole numbers 10 and 12 to get:

10 + 12 = 22

Step 2: Add the fractional parts separately.

Add the fractions 3/4 and 1/4 separately. To do this, find a common denominator, which in this case is 4. Then convert each fraction to have the same denominator and add the numerators.

For 10 3/4, the fraction 3/4 has the same denominator, so we keep it as is.

For 12 1/4, the fraction 1/4 also has the same denominator, so we keep it as is.

Then we add the numerators of the fractions:

3/4 + 1/4 = 4/4 = 1

Step 3: Add the results from Step 1 and Step 2.

Add the result from Step 1 (the sum of the whole numbers) to the result from Step 2 (the sum of the fractions):

22 + 1 = 23

Therefore, the sum of 10 3/4 and 12 1/4 is 23.

According the question given above the area of ABK is  100 square cm.

a) ACD = 50 square cm

b)AMCN = 225 square cm

c)ABK = 100 square cm

a) Tο calculate ACD, we need tο use the fοrmula fοr the area οf a trapezοid, which is:

Area = (base1 + base2) × height ÷ 2

Since CD is twice the length οf AB, we can let AB = x and CD = 2x. Let's alsο call the height οf the trapezοid h.

Then we have:

450 = (AB + CD) × h ÷ 2

450 = (x + 2x) × h ÷ 2

450 = 3xh ÷ 2

300 = 3xh

100 = xh

Nοw, we can use the fact that MA = MB tο find the area οf triangle ACD:

ACD = AB × h ÷ 2

ACD = xh ÷ 2

ACD = 100 ÷ 2

ACD = 50 square cm

b) Tο calculate AMCN, we need tο first find the length οf MN. Since MA = MB and NC = ND, we can use the fact that οppοsite sides οf a trapezοid are parallel tο find that AMCN is a parallelοgram. Therefοre, MN is equal tο AB.

Using the fοrmula fοr the area οf a parallelοgram, which is base × height, we have:

AMCN = AB × CD

AMCN = x × 2x

[tex]AMCN = 2x^2[/tex]

AMCN = 900 ÷ 2

AMCN = 225 square cm

c) Tο find the area οf triangle ABK, we need tο find the length οf BK. Since AB = x and CD = 2x, we knοw that AK and KC are alsο equal tο x. Therefοre, BK is equal tο DA, which is 2x.

Using the fοrmula fοr the area οf a triangle, which is base × height ÷ 2, we have:

The proper formula states that a sphere with a radius of [tex]15[/tex] has a volume of 4/3π([tex]15^{3}[/tex]).

The equation for a sphere's size is V = 3/3 r3, wherein r represents the radius and V is its volume. 1⁄2 of an object's circumference makes up its radius. Therefore, you may determine the radius first, then by the volumes, to get the contact area of a globe given its diameter.

Both a circle as well as a sphere are round, if you compare them. The difference among the two forms is that while a sphere has three dimensions, a circle only has two, which is why we can measure a sphere's volume and surface area.

The formula for the volume of a sphere is V = 4/3π[tex]r^{3}[/tex], where r is the radius of the sphere.

Substituting [tex]r=15[/tex], we get

Step-by-step explanation:

Three angles of a triangle add up to 180°

∴ w = 180 - (36 + 42)

= 180 - 78

w and m are supplementary angles:
m + w = 180

m + 102 = 180

m  = 180 - 102 = 78

Three angles of a triangle add up to 180°

m + 44 + n = 180

Yes, Pairing arrangements are possible.

[tex]$\frac{n!}{2^n (n/2)!}$[/tex]

If there are n cysteines, then there are n sulfur atoms that can form disulfide bonds. To form a pairing arrangement, we need to choose 2 sulfur atoms from the n sulfur atoms and connect them with a disulfide bond. We repeat this process until all sulfur atoms are paired up.

The number of ways to choose 2 sulfur atoms from n sulfur atoms is given by the binomial coefficient

[tex]$\binom{n}{2}$[/tex]

Once two sulfur atoms are paired up, we can remove them from the pool of sulfur atoms and continue pairing the remaining sulfur atoms in the same way.

Therefore, the total number of pairing arrangements is given by:

[tex]$\binom{n}{2} \cdot \binom{n-2}{2} \cdot \binom{n-4}{2} \cdots \binom{4}{2} \cdot \binom{2}{2}$[/tex]

which can be simplified as:

[tex]$\frac{n!}{2^n (n/2)!}$[/tex]

Since we are choosing pairs, we divide by 2 for each pair and the order of the pairs doesn't matter. Also, we divide by (n/2)! to account for the fact that the pairs can be arranged in any order.

Note- that n must be even for this formula to hold.

Therefore, the general formula for the number of different pairing arrangements when there are n cysteines (and n is even) is:
