Step-by-step explanation:

13.65 is rounded to 14

Answer:

14

Step-by-step explanation:

since your looking for the nearest whole number the first number behind the decimal is what determines if it goes to 14 or 13. because the number is 6 and is higher than 5 the number would be 14 but if the number was 4 than it would be 13. any number above 5 goes and 4 and below makes the number go down.

The ratio of Han's measurements and Tyler's measurements corresponds with polenta measurement

Given:

Polenta:

Cups of water = 5

Cornmeal = 2

Ratio of cups of water to cornmeal = 5 : 2

= 5/2

= 2.5

Han:

Cups of water = 3

Cornmeal = 1 1/5

= 6/5

Ratio of cups of water to cornmeal = 3 : 6/5

= 3 ÷ 6/5

= 3 × 5/6

= 15/6

= 2.5

Tyler:

Cups of water = 7 1/2

= 15/2

Cornmeal = 3

Ratio of cups of water to cornmeal = 15/2 : 3

= 15/2 × 1/3

= 15/6

= 2.5

Therefore, the ratio of Han's measurements and Tyler's measurements corresponds with polenta measurement.

Final answer:

The question involves mathematical ratios to determine the correct proportions for a polenta recipe. By setting up proper proportions, we confirm that Han's and Tyler's calculations for the amount of cornmeal and water needed are correct.

Explanation:

The question discusses proportions used in a recipe which relates to mathematical ratios. Han and Tyler are trying to determine how much cornmeal and water they need for polenta based on a recipe that calls for a specific ratio of these ingredients. To solve this, we must set up a proportion that maintains the constant ratio given by the recipe.

For Han's statement, since the recipe calls for 5 cups of water for every 2 cups of cornmeal, we can set up the following proportion:

5 cups water / 2 cups cornmeal = 3 cups water / x cups cornmeal

Multiply across the equal fractions (5 * x = 2 * 3)

x = 6/5 or 1.2 cups cornmeal, which confirms Han's statement as correct.

For Tyler's statement, using the same ratio:

2 cups cornmeal / 5 cups water = 3 cups cornmeal / x cups water

Multiply across the equal fractions (5 * 3 = 2 * x)

x = 15/2 or 7.5 cups water, which confirms Tyler's statement as correct as well.

The equation of a circle if the ends of the diameter are (18,-13) and (4,-3)​ is [tex](x-11)^{2}+(y+8)^{2}=74[/tex]

Given that ends of diameter are (18, -13) and (4, -3)

To find the equation of circle, let us first find the center (h, k) of the circle

We know that the center of the circle lies in the center of the diameter also. In order to find the center, get the average of both x and y

[tex]\mathrm{c}=\left(\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}\right)[/tex]

[tex]\begin{array}{l}{c=\frac{18+4}{2}, \frac{-13-3}{2}} \\\\ {c=\frac{22}{2}, \frac{-16}{2}} \\\\ {\mathrm{c}=(11,-8)}\end{array}[/tex]

These are the coordinates of the center of the circle

Now we need to find the radius, we need the center (h, k) and one of the given points (4, -3):

The equation of circle is given as:

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

[tex]\begin{array}{l}{(4-11)^{2}+(-3-(-8))^{2}=r^{2}} \\\\ {(-7)^{2}+(-3+8)^{2}=r^{2}} \\\\ {(-7)^{2}+(5)^{2}=r^{2}} \\\\ {49+25=r^{2}} \\\\ {r=\sqrt{74}}\end{array}[/tex]

So the equation of the circle is:

[tex]\begin{array}{l}{(x-11)^{2}+(y-(-8))^{2}=(\sqrt{74})^{2}} \\\\ {(x-11)^{2}+(y+8)^{2}=74}\end{array}[/tex]

The minimum possible area of the rectangle is 19.25 m² and the maximum possible area is 29.25 m².

To find the minimum and maximum possible areas of the rectangle, we need to consider the possible values that the length and width can take.

Given that the measured dimensions are 6 m by 4 m to the nearest whole unit, the minimum possible length would be 5.5 m (6 m - 0.5 m) and the minimum possible width would be 3.5 m (4 m - 0.5 m).

Similarly, the maximum possible length would be 6.5 m (6 m + 0.5 m) and the maximum possible width would be 4.5 m (4 m + 0.5 m).

To calculate the minimum and maximum possible areas, we multiply the minimum and maximum possible lengths by the minimum and maximum possible widths respectively. The minimum possible area would be 5.5 m x 3.5 m = 19.25 m² and the maximum possible area would be 6.5 m x 4.5 m = 29.25 m².

He has been withdrawing money for 69 days.

Step-by-step explanation:

Amount of credit card = $5000

Let,

x be the number of days

Amount after withdrawing $45 each day for x days = $1895

Amount left = Total amount - Withdrawal amount per day * number of days

1895 = 5000 - 45*x

[tex]1895=5000-45x[/tex]

Solving for x;

[tex]1895-5000=-45x\\-3105=-45x\\-45x=-3105[/tex]

Dividing both sides by -45

[tex]\frac{-45x}{-45}=\frac{-3105}{-45}\\x=69[/tex]

Answer:

The combined cost of 1 pound of salmon and 1 pound of swordfish is $16.66

Step-by-step explanation:

Let us assume the cost of 1 pound salmon = $ m

So the cost of 1 pound of 1 pound swordfish cat = $ ( m - 0.20)

Now, the Amount of salmon purchased  = 2 1/2 pounds

[tex]2\frac{1}{2}  = 2 + \frac{1}{2} = 2 + 0.5 = 2.5[/tex]

So, the amount of salmon purchased = 2.5 pounds

Cost of buying 2.5 pounds = 2.5 x ( 1 pound cost)

= 2.5 ( m) = $ 2.5 m  ...... (1)

Also, the Amount of swordfish purchased  = 1 1/4 pounds

[tex]1\frac{1}{4}  = 1 + \frac{1}{4} = 1 + 0.25 = 1.25[/tex]

So, the amount of swordfish purchased = 1.25 pounds

Cost of buying 1.25 pounds = 1.25 x ( 1 pound cost of swordfish)

= 1.25 ( m - 0.20) = $ 1.25 m - 0.25       .... (2)

Now, the combined cost paid  = $ 31.25

⇒Cost of buying (2.5 pounds salmon  +  1.25 pounds swordfish) = $ 31.25

or, 2.5 m +   1.25 m - 0.25  = 31.35       (from (1) and (2))

or, 3.75 m = 31.60

or, m = 31.60/3.75 =  8.43

⇒ m = $8.43

So, the cost of 1 pound salmon = m = $8.43

and the cost of 1 pound swordfish = m - 0.20 = $8.43 - 0.20 = $ 8.23

Hence, the combined cost  1 pound of salmon and 1 pound of swordfish = $8.43 + $ 8.23 =  $ 16.66

[tex]m\angle B=54^{\circ}[/tex]

[tex]m\angle BAD=36^{\circ}[/tex]

[tex]m\angle CDA=90^{\circ}[/tex]

[tex]BAC=72^{\circ}[/tex]

Step-by-step explanation:

Given:

[tex]\overline{AB}\cong \overline{AC},[/tex]

[tex]\overline{AD}[/tex] bisects angle BAC

[tex]m\angle C=54^{\circ}[/tex]

Triangle ABC is isosceles triangle, because [tex]\overline{AB}\cong \overline{AC}.[/tex] Angles adjacent to the base of isosceles triangle ABC are congruent.

Hence,

[tex]m\angle C=m\angle B=54^{\circ}[/tex]

The sum of the measures of all interior angles is 180°, so,

[tex]m\angle B+m\angle C+m\angle BAC=180^{\circ}\\ \\m\angle BAC=180^{\circ}-2\cdot 54^{\circ}=72^{\circ}[/tex]

Since [tex]\overline{AD}[/tex] bisects angle BAC, angles BAD and CAD are congruent by definition of angle bisector. So,

[tex]m\angle BAD=m\angle CAD=\dfrac{1}{2}m\angle BAC=\dfrac{1}{2}\cdot 72^{\circ}=36^{\circ}[/tex]

AD ia angle bisector in isosceles triangle drawn to the base, so it is the height. Thus, AD and BC are perpendicular. So,

[tex]m\angle CDA=90^{\circ}[/tex]

Answer:

The needed quadratic equation is : [tex]p(x) = x^2 -3x + 10[/tex]

Step-by-step explanation:

The given equation is of the form [tex]p(x) = ax^2 + bx + c[/tex]

The given solutions of the equations are:

x = 3 +i, x = 3 - i

Now, if x = a is the zero of the polynomial p(x)

⇒(x -a ) is the root of the given polynomial.

⇒ (x - ( 3+i)) and (x - ( 3+i)) are the given roots for p(x)

P(X) = PRODUCT OF ALL ROOTS

⇒ p(x) = (x - ( 3+i))(x - ( 3-i))  = ( x-3 -i)(x -3+i)

Now, [tex](a-b)(a +b) = a^2 - b^2\\\implies ( (x-3)-i)((x-3)+i) = (x-3)^2 - (i)^2 = x^2 +9 - 3x -(-1)\\= x^2 +10 - 3x\\\implies p(x) = x^2- 3x + 10[/tex]

Hence, the needed quadratic equation is : [tex]p(x) = x^2 -3x + 10[/tex]

Answer:

P(E or F) = 0.75

Step-by-step explanation:

Given;

P(E)=0.30

P(F)=0.45

We need to find probability of P(E or F).

Now by General theorem of probability addition theorem:

P(E or F) = P(E) + P(F) - P(E and F)

For mutually exclusive events, P(E and F) = 0

So, P(E or F) = P(E) + P(F) = [tex]0.3 +0.45 = 0.75[/tex]

Hence P(E or F) = 0.75

Probabilities are used to determine the chances of an event.

The probability of P(E or F) is 0.75

The parameters are given as:

[tex]\mathbf{P(E) = 0.30}[/tex]

[tex]\mathbf{P(F) = 0.45}[/tex]

[tex]\mathbf{P(E\ or\ F) = P(E) + P(F)}[/tex]

So, the equation becomes

[tex]\mathbf{P(E\ or\ F) = 0.30 + 0.45}[/tex]

[tex]\mathbf{P(E\ or\ F) = 0.75}[/tex]

Hence,  the probability of P(E or F) is 0.75

Because of the answers that you gave I'm going to assume the radians were 3pi/4. That would be A, 135 degrees.

If this is the wrong amount of radians please let me know.

The radian measures of the given degree measures are 3π / 4 Rad, π Rad, 3π / 2 Rad and 2π

One radian is the measure of a central angle subtended by an arc that is equal in length to the radius of the circle. When no symbol is used, radians are assumed. When degrees are the unit of angular measure, the symbol "°" is written. Note that the radian is a derived unit in the International System of Units (SI).

Given are some degree measurements, 135° 180° 270° 360°, we need to convert them into radians.

Since, we know that,

1 Rad = 1 Deg × π / 180

Therefore,

1) 135° = 135 × π / 180

= 3π / 4 Rad

2) 180° = 180 × π / 180

= π Rad

3) 270° = 270 × π / 180

= 3π / 2 Rad

4) 360° = 360 × π / 180

= 2π

Hence, the radian measures are 3π / 4 Rad, π Rad, 3π / 2 Rad and 2π
