what is tan 25° to the nearest hundredth​

Answer:

$0.09

Step-by-step explanation:

1 pound = 16 ounces

So 2 pounds = 32 ounces

Write a proportion:

$2.88 / 32 oz = x / 1 oz

Solve:

x = $0.09

The price per ounce is $0.09.

Final answer:

To find the price per ounce of a 2-pound broccoli bag costing $2.88, divide the total price by the number of ounces (32), resulting in a price per ounce of $0.09.

Explanation:

To calculate the price per ounce of a 2-pound bag of broccoli that costs $2.88, you first need to know the total number of ounces in the bag. Since there are 16 ounces in 1 pound, a 2-pound bag contains 32 ounces (16 ounces/pound x 2 pounds). To find the price per ounce, you divide the total price of the bag by the total number of ounces.

Price per ounce calculation:

Total price of the bag = $2.88

Total ounces in the bag = 32 ounces

Price per ounce = Total price of the bag / Total ounces in the bag

Price per ounce = $2.88 / 32 ounces

Therefore, the price per ounce is $0.09.

Answer:

4. Option 3: 65.1 cm^2

5. Option 3: 3.4 inches^2

Step-by-step explanation:

Question 4 :

We can see that there is a rectangle and a half circle in the picture.

So we will find the area of both separately

For the area of rectangle

Area=length*width

=8*5

=40 cm^2

We know that the line which is representing the diameter has length 8 cm

To find the radius

r=d/2

=8/2

=4 cm

As we cannot find the area of half circle, we will find the area of full circle and will divide it in half.

So,

area= πr^2

=3.14*(4)

=3.14*16

=50.24 cm^2

Area of half circle=(Area of full circle)/2

=50.24/2

=25.12 cm^2

So the area of shape will be

Area of rectangle+area of half circle

=40 cm^2+25.12 cm^2

=65.12 cm^2

Rounding off to nearest 10 will give 65.1 cm^2

So, option 3 is the correct answer ..

Question 5 :

To find the area of shaded region we have to find the area of circle and area of square in which it is inscribed

So,

area of circle= πr^2

=3.14*(2)^2

=3.14*4

=12.56 inches^2

And to find the area of square we need one of its side, we can clearly see that the diameter of circle will be equal to the side of square

So,

Side of square=s=r*2

=2*2

=4 inches

Area of square=s^2

=4^2

=16 inches^2

To find the area of shaded region we have to subtract the area of circle from the area of square

So,

Area of Shaded Region=Area of Square-Area of Circle

=16-12.56

=3.44 inches^2

Rounding off to the nearest 10 will give 3.4 inches^2 ..

So, option 3 is the correct answer ..

Answer:

x = 30517578124/29296875

Step-by-step explanation:

Solve for x:

3125 = 3 x + 1/9765625

Put each term in 3 x + 1/9765625 over the common denominator 9765625: 3 x + 1/9765625 = (29296875 x)/9765625 + 1/9765625:

3125 = (29296875 x)/9765625 + 1/9765625

(29296875 x)/9765625 + 1/9765625 = (29296875 x + 1)/9765625:

3125 = (29296875 x + 1)/9765625

3125 = (29296875 x + 1)/9765625 is equivalent to (29296875 x + 1)/9765625 = 3125:

(29296875 x + 1)/9765625 = 3125

Multiply both sides of (29296875 x + 1)/9765625 = 3125 by 9765625:

(9765625 (29296875 x + 1))/9765625 = 9765625×3125

(9765625 (29296875 x + 1))/9765625 = 9765625/9765625×(29296875 x + 1) = 29296875 x + 1:

29296875 x + 1 = 9765625×3125

9765625×3125 = 30517578125:

29296875 x + 1 = 30517578125

Subtract 1 from both sides:

29296875 x + (1 - 1) = 30517578125 - 1

1 - 1 = 0:

29296875 x = 30517578125 - 1

30517578125 - 1 = 30517578124:

29296875 x = 30517578124

Divide both sides of 29296875 x = 30517578124 by 29296875:

(29296875 x)/29296875 = 30517578124/29296875

29296875/29296875 = 1:

Answer:  x = 30517578124/29296875

For this case:

We rewrite the equation as:

[tex]5 ^ {- 10 + 3x} = 3.125[/tex]

We find ln on both sides of the equation to remove the exponent variable:

[tex]ln (5 ^ {- 10 + 3x}) = ln (3,125)[/tex]

Applying properties of logarithm we have:

[tex](-10 + 3x) ln (5) = ln (3.125)[/tex]

We apply distributive property:

[tex]-10ln (5) + 3xln (5) = ln (3,125)[/tex]

We clear the value of "x":

[tex]3xln (5) = ln (3,125) + 10ln (5)\\x = \frac {ln (3.125)} {3ln (5)} + \frac {10ln (5)} {3ln (5)}\\x = \frac {ln (3.125)} {3ln (5)} + \frac {10} {3}[/tex]

ANswer:

[tex]x = \frac {ln (3.125)} {3ln (5)} + \frac {10} {3}[/tex]

Answer:

$4,100

Step-by-step explanation:

Final answer:

The dealership's profit from selling the two vehicles, after considering a 15% markup on the four-door sedan and a 25% markup on the trade-in vehicle, was $4,100.

Explanation:

To calculate the dealership's profit on the two vehicles, we need to consider the markup on each transaction.

Profit from the Four-Door Sedan

The dealership purchased the sedan for $19,000 and sold it at a 15% markup. The markup is calculated as 15% of the purchase price:

Markup on sedan = 0.15 times $19,000 = $2,850

The selling price of the sedan would thus be:

Sell price of sedan = Purchase price + Markup = $19,000 + $2,850 = $21,850

Profit from the Trade-In Vehicle

After trading in the first car and effectively reducing its cost by $5,000, the dealership then sells the trade-in at a 25% markup. First, we calculate the trade-in's sale price:

Trade-in value = $5,000

Markup on trade-in = 0.25 times $5,000 = $1,250

Sell price of trade-in = Trade-in value + Markup = $5,000 + $1,250 = $6,250

Total Profit

The total profit is the sum of profits from both vehicles:

Total profit = Markup on sedan + Markup on trade-in = $2,850 + $1,250 = $4,100

Therefore, the dealership's profit on these two vehicles was $4,100.

x = 17

Step-by-step explanation:

You already know that proper fractions have numerators smaller than the denominators, such as 1/2, 2/10 or 3/4, making them equal less than 1. The improper fraction has a numerator larger than the denominator. And mixed numbers have a whole number sitting next to a proper fraction -- for example, 4 3/6 or 1 1/2. As you work on converting improper fractions, you’ll find yourself using your knowledge of division.

Write down the improper fraction -- for example, 27/6. The fraction bar means you need to divide 27 by 6.

Divide 27 by 6. The answer is 4, with a remainder of 3. Use the answer as the whole number part of the mixed number, and place the remainder over the original denominator: 4 3/6.

Reduce the fraction, if necessary. For example, 3/6 equals 1/2 (the lowest common denominator of 3 and 6 is 3, so divide both the numerator and the denominator by 3 to reduce the fraction to 1/2).

If it is a mixed number fraction:  1 1/2

1. multiple the whole number and the denominator 2 x 1 = 2

2. Add that to the numerator 2+1= 3

*Denominator stays the same

3. example answer is...  3/2

Answer:

It would most likely 0.02 - 0.03 because if u think about it there wings don't weight more than about 0.1  and if the wings can hold up the body of the butterfly then i would assume that it would weight between 0.02 - 0.03.

Step-by-step explanation:

To find out how much Jennifer has saved, you start by tripling the amount Matthew has saved, which is $81. Then you subtract $26 from the result to get $217. Therefore, Jennifer has saved $217.

From the problems statement, we can model Jennifer's savings using the mathematical model, where Jennifer's savings is equal to triple Matthew's savings minus $26. Given that Matthew’s savings amount to $81, we can multiply Matthew's savings by three, which equals $243. Then, to find Jennifer's savings, we subtract $26 from $243 resulting in $217. Therefore, Jennifer has $217 saved.

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]\dfrac{2}{3}(n-6)=5n-43\qquad\text{multiply both sides by 3}\\\\2(n-6)=15n-129\qquad\text{use the distributive property}\\\\2n-12=15n-129\qquad\text{add 12 to both sides}\\\\2n=15n-117\qquad\text{subtract}\ 15n\ \text{from both sides}\\\\-13n=-117\qquad\text{divide both sides by (-13)}\\\\n=9[/tex]

The equation 2/3(n-6) = 5n - 43 is solved by distributing, combining like terms, and isolating the variable n to find that n = 9.

To solve the equation 2/3(n-6) = 5n - 43, first distribute the 2/3 across the parentheses: 2/3n - 2/3  6 = 5n - 43. This simplifies to 2/3n - 4 = 5n - 43. Next, add 4 to both sides to get 2/3n = 5n - 39. Multiply everything by 3 to clear the fraction: 2n = 15n - 117. Now, we will subtract 15n from both sides to get -13n = -117. Finally, divide by -13 to find n: n = 9. This is the value of n that solves the original equation.

Answer:

The equation of the circle is (x + 3)² + (y + 5)² = 36

Step-by-step explanation:

* Lets revise the standard form of the equation of the circle

- The center-radius form of the circle equation is in the format  

  (x – h)² + (y – k)² = r², where the center is the point (h, k) and  

  the radius is r.  

- This form of the equation is helpful, because you can easily find  

  the center and the radius.

* Now lets solve the problem

∵ The center of the circle is (-3 , -5)

∵ The center of the circle in the equation is (h , k)

∴ h = -3

∴ k = -5

∴ The equation of the circle is (x - -3)² + (y - -5)² = r²

∴ The equation is (x + 3)² + (y + 5)² = r²

* Now lets find the value of r²

∵ The length of the radius of the circle is 6 units

∴ r = 6

∴ r² = (6)² = 36

∴ The equation of the circle is (x + 3)² + (y + 5)² = 36

Final answer:

To find the probability that Ricardo will have a quiz on Tuesday, Thursday, or Friday, we add the individual probabilities for each of those days, resulting in a total probability of 60%.

Explanation:

Probability is a measure of the likelihood of an event occurring. To find the probability that Ricardo will have a quiz on Tuesday, Thursday, or Friday, we add the individual probabilities for each of those days.

Probability of having a quiz on Tuesday = 0.2

Probability of having a quiz on Thursday = 0.1

Probability of having a quiz on Friday = 0.3

Total probability = Probability on Tuesday + Probability on Thursday + Probability on Friday = 0.2 + 0.1 + 0.3 = 0.6. Expressing this as a percentage, we get 60%.

Center (7, -5) and radius=6

Step-by-step explanation:

The question is on center and radius of a circle

The general circle equation is given as (x-h)² + (y-k)²= r² where the center is (h,k) and radius is r

Given   (x-7)^2 + (y+5)^2 = 36?

            (x-7)²  + (y+5)²= 6²

h=7 and y=-5 and r=6

ANSWER

Center:(7,-5)

Radius:r=6

EXPLANATION

The given circle has equation;

[tex] {(x - 7)}^{2} + {(y + 5)}^{2} = 36[/tex]

We can rewrite this as:

[tex]{(x - 7)}^{2} + {(y - - 5)}^{2} = {6}^{2} [/tex]

Comparing this to the standard equation of the circle:

[tex]{(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} [/tex]

we have h=7,k=-5, and r=6.

Therefore the center (h,k)=(7,-5) and the radius is r=6.
