Robin's family breeds Great Danes. In the last litter, one of the puppies grew at an unusually consistent rate. At birth, he weighed two pounds. At eight months, he weighed 110 pounds.

Answers

Answer 1

Let's assume that you're being asked to write a formula for the dog's weight.

In this case, w = (weight after x months) = (initial weight) (1 + r)^x

We know the initial and final weights: 2 lb and 110 lb. We also know that the time period involved is 8 months. What is the "consistent" rate at which the dog gains weight?

110 lb = (2 lb) (1 + r)^8

Let's solve this for r.

Dividing both sides by 2 lb, 55 = (1 + r)^8

Finding the 8th root of both sides: 1.65 = 1 + r

Solving for r, r = 0.65

The dog gains weight at the consistent rate of 0.65 lb/month.

Check: Does (2 lb) (1.65)^8 come out to 110 lb?

(2 lb)(54.94) = 109.9 lb (very close indeed to 110 lb).

Answer 2

Answer:

A. An additional month of growth is associated with an additional 13.5 pounds of weight.

Answers

Answer: B

Picture 1 shows the reflection of ABC 180° clockwise about the origin. To draw A'B'C' we draw the line segments AO, BO, and CO and extend them such that O is the midpoint of line segments AA', BB', and CC' respectively.

Picture 2 shows the line y=-x (the yellow line.) This is the line containing all points of the form (x, -x), that is, this points contains (1, -1), (-2, 2) etc...

We see that point C' is already on this line, and we draw the reflections of points B and C with respect to this line, to find B'' and C'' with coordinates as shown in the figure.

how much apple juice does each person get if 6 people share 2 and 2/3 quarts equally

Answers

First convert 2 2/3 to an improper fraction. That comes out to 8/3. Then multiply 8/3 with the inverted fraction 1/6. It comes out to be 8/18, but most require simplification, which is 4/9 quart per person.

The fraction of apple juice shared by 6 people is A = 4/9 of the apple juice

What is a Fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the fraction of apple juice shared by 6 people be A

Let the total number of people be represented as n = 6 people

Now , the fraction of total amount of apple juice = 2 2/3

The fraction of total amount of apple juice T = ( 8/3 ) of apple juice

And , the equation is

A = fraction of total amount of apple juice T / total number of people n

On simplifying , we get

A = ( 8/3 ) / 6

A = ( 8/18 )

Divide by 2 on both numerator and denominator of the fraction , we get

A = 4/9 of the apple juice

Therefore , the value of A is 4/9

Hence , the fraction of apple juice is ( 4/9 ) equally

Two right triangles are congruent. Find the value of x.
right triangle with angle of 33 degrees, right triangle with angle of 9 x minus 15 degrees
Select one:
a. 5
b. 6
c. 8
d. 12

Answers

Given that the two right triangles are congruent, there are two possibilities.

9x - 15 is equal to the angle 33° or 9x - 15 is equal to the other angle of the first triangle.

Let's probe with the first option:

9x - 15 = 33 => 9x = 33 + 15 = 48

=> x = 48 / 9 = 5,33, which is no in the list of options.

Now, let's probe the second option.

The other angle of the first right triangle is 90° - 33° = 57°

Then, 9x - 15 = 57

=> 9x = 57 + 15 = 72

=> x = 72 / 9 = 8

Which is the option c. 8.

So, I am sure that if you have a figure it will be compatible with that answer, else yet the procedure to find the answer is what I have used here.

Evaluate the dot product a⃗ ⋅b⃗ of a⃗ =3i^−8j^ and b⃗ =−2i^−6j^.

Answers

The "dot product" of two vectors has several different formulas.

Since you are given the x- and y-coordinates of both vectors a and b, we can apply the formula

a dot b = ax*bx + ay*by, where ax=x-component of vector a, by=y comp of vector b, and so on.

So, for the problem at hand, ax * bx + ay * by becomes

3(-2) + (-8)(-6) = -6 + 48 = 42 (answer). Note that the dot product (or "scalar product" is itself a scalar.

Final answer:

The dot product of vectors a⃗ =3i^−8j^ and b⃗ =−2i^−6j^ is calculated by multiplying the corresponding components of the vectors and summing the results, giving a final dot product of 42.

Explanation:

The dot product of two vectors a and b is calculated by multiplying the corresponding components of the vectors and summing the results. So, given the vectors a⃗ =3i^−8j^ and b⃗ =−2i^−6j^, the dot product can be found as follows:

a⃗ ⋅b⃗ = (a_x * b_x) + (a_y * b_y)

Therefore, substituting the known values: a⃗ ⋅b⃗ = (3 * -2) + (-8 * -6) = -6 + 48 = 42

So, the dot product a⃗ ⋅b⃗ for vectors a⃗ =3i^−8j^ and b⃗ =−2i^−6j^ is equal to 42.

Final answer:

To solve the formula F=J+Jrt for 't', first, subtract 'J' from both sides to get F-J=Jrt. Then, divide both sides by 'Jr', for the final equation for 't' = (F-J)/Jr.

Explanation:

This physics-related mathematics question is asking you to solve the given formula F=J+Jrt for 't'. To isolate 't', we first want to eliminate 'J' from the right side. We do this by subtracting 'J' from both sides of the equation. This gives us F-J=Jrt.

Three friends all live on the same street that runs west to east. Ben lives 4 blocks from Ann. Carl lives 2 blocks from Ben. If the street is represented by a number line and Ann's house is located at 0, what are the possible locations for Carl's house?

Answers

Answer:

The possible locations are,

2, -2, 6 or -6

Step-by-step explanation:

Given,

The location of Ann's house in the number line = 0,

∵ Ben lives 4 blocks from Ann.

So, the possible location of Ben's house = 4 ( right of ann's house ) or - 4 ( left of ann's house )

Now, Carl lives 2 blocks from Ben,

So, the possible location of Carl's house

Case 1 : If Ben's house location is 4 = 2 ( left of ben's house ) or 6 ( right of ben's house )

Case 2 : If Ben's house location is -4 = -2 ( right of ben's house ) or -6 ( left of ben's house )

The possible locations of Carl's house are - 6, 6, 2 or - 2

Let :

Ben's location = B

Carl's position = C

Ann's position = A

Using the Number line illustration :

Ann's position = 0

Ben's possible positions :

4 blocks(units) from Ann = ± 4

Carl's location :

2 blocks from Ben-4 ± 2 = (-4 - 2) or (-4 + 2) = - 6 or - 2 +4 ± 2 = (4 + 2) or (4 - 2) = 6 or 2

Last year Jeremy had $7900 in medical expenses. If his AGI was $89,000, will he be able to deduct his medical expenses and if so, what amount?

Answers

medical expenses are deducted on schedule A - which is required to be over 7.5% of AGI

Answer:

He will be able to deduct his medical expenses by $1225.

Step-by-step explanation:

If his medical expenses are over 7.5% of his AGI he can reduce it to 7.5%.

His AGI was $89,000. How much is 7.5% of that?

0.075*89000 = $6675.

His expenses are over 7.5%, so yes, he can reduce.

He can reduce from $7900 to $6675, so 7900 - 6675 = $1225

How many pounds of cashew nuts worth 75 cents a pound must be mixed with 10 pounds of pecans worth $1.50 a pound to make a mixture worth $1.00 a pound? Which of the equations could be used to solve for p, the pounds of cashew nuts?

Answers

Let c represent the weight of cashews and p the weight of pecans.

Then c + 10 = total weight of the nut mixture.

An equation for the value of the mixture follows:

$1.50(10 lb) + $0.75c = (c+10)($1.00)

Solve this equation for c: 15 + .75c = c + 10. Subtract .75c from both sides:

15 = 1c - 0.75c + 10. Then 5=0.25c, and c = 5/0.25, or 20.

Need 20 lb of cashews.

Check: the pecans weigh 10 lb and are worth $1.50 per lb, so the total value of the pecans is $15. The total value of the cashews is (20 lb)($0.75/lb), or $15. Does (20 lb + 10 lb)($1/lb) = $15 + $15? Yes. So c= 20 lb is correct.
