Answer: He has 287 home runs

Step-by-step explanation:

Let's define:

H = home runs of Hank

J = home runs of Jones.

We know that:

H = 2*J - 181

H = 755

Then we can replace the second equation into the first one:

755 = 2*J - 181

(755 - 181)/2 = J

287 = J

Answer:

Yes

Step-by-step explanation:

Step 1: Define

f(x) = x - 3

(5, 2) is equal to x = 5, f(x) = 2

Step 2: Substitute and Evaluate

2 = 5 - 3

2 = 2

The amount of drug left in the blood stream at 2pm is: 6.10 mg

The exponential growth function we are given is expressed as:

y = y₀[tex]e^{-0.36t}[/tex]

where:

y is amount of drug in the blood stream

y₀ is amount of drug injected into the blood stream

t is number of hours after the drug was injected.

Thus, we are told that 15 milligrams was injected into the blood stream at 11:30 am. Thus, the amount of drug left in the blood stream at 2pm which is 2.5 hours after is:

y = 15 * [tex]e^{(-0.36 * 2.5)}[/tex]

y = 15 * 0.4066

y = 6.10 mg

The polar coordinates of the point P are (-6, π/3).

To identify the coordinates of the point in polar form based upon the given conditions, we need to use the polar coordinate system. In this system, a point is represented by an ordered pair (r, θ),

where r is the distance from the origin to the point, and θ is the angle that the line segment connecting the point to the origin makes with the positive x-axis, measured in a counterclockwise direction from the positive x-axis to the line segment.

Let's consider an example to understand this concept better.Suppose we are given the point P with rectangular coordinates (-3, -3√3). We need to find its polar coordinates.

Let's begin by finding the distance r from the origin to the point P. We can use the distance formula for this purpose.

We get:r² = (-3)² + (-3√3)² = 9 + 27 = 36r = ±6

Since P lies in the third quadrant, its distance from the origin must be negative. Therefore, we take r = -6.

Now, we need to find the angle θ that the line segment OP makes with the positive x-axis. We can use the tangent function for this purpose. We get:tan θ = (-3√3)/(-3) = √3θ = π/3 (since P lies in the third quadrant)

Answer: 40%  

Step-by-step explanation:

To write 8/20 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % . 8/20 * 100 = 0.4 * 100 = 40% And finally we have: 8/20 as a percent equals 40%

Answer:

$5,700 was invested in the 7% account

Step-by-step explanation:

Let the amount invested in 7% interest account be x while the other account is y

Total amount invested is &12,350

Thus:

x + y = 12,350 ••••(i)

interest on 7% = 7% of x = 7/100 * x = 7x/100

Interest on 6% = 6% of y = 6/100 * y = 6y/100

Since both have same interest;

7x/100 = 6y/100

7x = 6y

y = 7x/6

Put this into equation i

x + 7x/6 = 12,350

Multiply through by 6

6x + 7x = 74,100

13x = 74,100

x = 74,100/13 = $5,700

Answer:

20 3/4

Step-by-step explanation:

21 4/8 is the same as 21 2/4 or even 21 1/2, but for this equation, it would be easier to put it as 21 2/4.

Then you would just minus 21 4/8 by 3/4 which would then leave you with 20 3/4.

Answer: Difference between the volumes of 5cm x 5cm x 5cm cube and 2cm x 4cm x 16 cm cuboid = 3 cm^3.

Step-by-step explanation: Volume of cube of side "a" =a^3

In the question, a=5cm

Therefore, the Volume of cube = 125 cm ^3

Volume of cuboid = l x b x h

In the question, l = 2cm, b = 4cm, h = 16cm

Therefore, Volume of cuboid= 128 cm^3

Hence, the difference in their volumes = 3 cm^3

Option (D)

Step-by-step explanation:

If a point (h, k) divides the line segment having ends at [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] in the ratio of m : n then,

h = [tex]\frac{mx_2+nx_1}{m+n}[/tex]

k = [tex]\frac{my_2+ny_1}{m+n}[/tex]

If a point Q(h, k) divides the segment with ends A(-4, 6) and B(6, 1) in the ratio of 3 : 2 then,

h = [tex]\frac{3(6)+2(-4)}{3+2}[/tex]

  = [tex]\frac{18-8}{5}[/tex]

h = 2

k = [tex]\frac{3(1)+2(6)}{3+2}[/tex]

  = [tex]\frac{3+12}{5}[/tex]

k = 3

Therefore, Coordinates of the point Q are (2, 3).

Option (D) will be the answer.

Step-by-step explanation:

the length of the diagonal of the suitcase is 30 in.

pythagorean theorem: a^2+b^2=c^2

(the length times the height=the diagonal)

So, 24^2 + 18^2=something

24^2=576

18^2=324

576+324= 900

square root of 900=30

so, c equals 30

therefore the diagonal =30 , so there's plenty of space to put the umbrella because it's less long than the diagonal
