Suppose your friends parents invest $15,000 in an account paying 4% annually. What will the balance be after 9 years?

Answers

Answer 1

Here's the equation for one year:
0.04(15000) + 15000
Because it is 9 years:
0.36(15000) + 15000
We can make it simpler:
1.36(15000)
Multiply:
20400
Their balance is $20400

Answers

Hey there !

Hope it helps you :)

Answer:

Option A. [tex]cot\theta = -1[/tex]

Step-by-step explanation:

[tex]\frac{tan^{3}\theta -1}{tan\theta -1}-sec^{2}\theta +1=0[/tex]

we have to the value of [tex]cot\theta[/tex]

We further solve the equation

[tex]\frac{(tan\theta -1)(tan^{2}\theta +1+tan\theta )}{(tan\theta -1)}-sec^{2}\theta+1=0[/tex] [a³- b³= (a-b)(a² + b²+ ab)]

[tex]sec^{2}\theta +tan\theta -sec^{2}\theta +1=tan\theta +1=0[/tex]

[tex]\frac{1}{cot\theta }=-1[/tex]

[tex]cot\theta = -1[/tex]

Therefore Option A. [tex]cot\theta = -1[/tex] is the answer.

Question 2 Unsaved Cat is 5 less than twice Dog's age. Cat is 11 years old. Find Dog's age.

Answers

The dog is 8 years old because If you take 8 and multiply it by 2 you get 16 and then you subtract 5 and you get 11 years old or the cats age

Let the dog's age be called x.

From the given statement, the following equation can be framed

Cat's age = 2*x -5

We are given to know that Cat's age is 11 years

So, we have:

11 = 2x -5

2x = 16

x = 16/2

x = 8

Dog's age = 8 years

factorise 36n(squared) divide by 25 minus 1

Answers

Answer:

[tex]( \frac{36n^{2} }{25} - 1) [/tex] factors to become [tex]( \frac{6}{5}n - 1)( \frac{6}{5}n + 1) [/tex]

Explanation:
The binomial [tex]( \frac{36n^{2} }{25} - 1) [/tex] is what is called a difference of two squares which can be identified by the equation being in the form (a² - b²) where both terms can be square-rooted.

Because the equation is a difference of two squares, its factors will be in the form: (a - b)(a + b).

With a² = [tex]\frac{36n^2}{25}[/tex] and b² = 1, we can find the square root of both and plug them into the above factor form.

√(36n² / 25) = 6n/5
√1 = 1

So the factors are [tex](\frac{6}{5}n -1)(\frac{6}{5}n +1)[/tex]

The base of a triangular prism is an isosceles right triangle with a hypotenuse of
√50 centimeters. The height of the prism is 8 centimeters. Find the surface area of the triangular prism. Round your answer to the nearest tenth.

Answers

Are sure that is right

SA= Lateral Area + Area (of base)

Lateral area = perimeter of base x height

An isosceles triangle has two congruent base segments. The hypotenuse of an isosceles right triangle is (length of base segment) x (the square root of 2). I did the math for you (shown above) to get 5 as a base.

So 5 + 5 + square root of 50 is your perimeter

Multiply the perimeter times your height (8) and you get the lateral area.

Add your lateral area to the base area (triangle = 1/2 bh)

LA = 136.568...
Area of Triangle base = 12.5

Surface area = 149.068... square cm

how farare 27and -54 apart on the number line

Answers

81..... sorry if I’m wrong

How far are 27 and -54 apart on the number line?

Solution:

If we see on the number line , 27 is 27 units apart from 0 and it is 27 units to the right of 0

And, -54 is 54 units apart from 0 and it is 54 units to the left of 0. So, -54 is in opposite direction with respect to 27.

So, To find how far is 27 from -54 we must add 27 and 54

As, 27+54=81

So, -54 and 27 are 81 units away from each other.

Answer:81 units

For the first part:

Every shirt she grabs, will cost her dollars, so if she grabs 3 shirts, then the cost of the shirts is:

[tex]12+12+12=3(12)[/tex]

With the same rationale, if she grabs 2 pairs of jeans, the cost of the jeans is:

[tex]19+19=2(19)[/tex]

So, her total is:

[tex]3(12)+2(19)[/tex]

If you subtract 3 from the total, then the expression is:

[tex]3(12)+2(19)-3=36+38-3=71[/tex]

For the second part:

If she's paying 3 less for each shirt, then the cost of 3 shirts will become:

[tex](12-3)+(12-3)+(12-3)=3(12-3)[/tex]

In the same fashion, for the two jeans:

[tex](19-3)+(19-3)=2(19-3)[/tex]

So the expression for the total cost is:

[tex]3(12-3)+2(19-3)=36-9+38-6=59[/tex]

For number three:

The amounts are different because the cost of the total purchase is different than the cost of each element that makes up the total purchase.

For number four:

If you're the owner, you want to give the smallest amount of discount (the one in part 1/a).

So you could clarify by saying there's 3 dollars of the TOTAL purchase's cost.

a circle has an area of 81 3.14 units . what is the diameter in terms of 3.14a circle has an area of 81 Pi square units what is the diameter of the circle

Answers

You have posted 2 separate questions here. Please, next time, separate them with a blank line:

A circle has an area of 81 3.14 units . what is the diameter in terms of 3.14?

I'd prefer you write this as
"A circle has an area of 81 pi units . what is the diameter in terms of pi?

Area of a circle = A = pi*r^2. Note that r= diameter / 2. Here, the area is 81 pi square units, or 9^2 * pi square units, which means that the radius is 9 units. The diameter is then 2(9 units) = 18 units.

Your second question, separated from the first, is:

"a circle has an area of 81 Pi square units what is the diameter of the circle?"

Use the following formula or formulas: d = 2*r; A = pi*r^2; A = pi*(d/2)^2. Find r first, and then find d.

Answer:

18 units

Step-by-step explanation:

[tex]\pi r^2=81\pi[/tex]

Solve for [tex]r[/tex]:

[tex]\pi r^2=81\pi \\r^2=81\\r=9[/tex]

Knowing diameter is 2*r, we can apply the formula to find diameter

While bowling with friends, Brandy rolls a strike in 5 out of 10 frames. What is the experimental probability that Brandy will roll a strike in the first frame of the next game? Enter your answer as a simplified fraction.

Answers

Brandy has a strike rate of 6 out of 10 frames. So the probability that Brandy will make a strike is 6/10 = 0.6. So, if Brandy has one roll in the first frame of the next game , the probability he will have a strike is 0.6 or 60%.

It 5/10 probability and 5/10 simplified is 1/2

Final answer:

The experimental probability of Brandy rolling a strike in the first frame of the next game is 1/2.

Explanation:

To find the experimental probability that Brandy will roll a strike in the first frame of the next game, we need to divide the number of times Brandy rolled a strike in the first frame by the total number of frames. In this case, Brandy rolled a strike in 5 out of 10 frames, so the experimental probability is 5/10, which simplifies to 1/2.

Given: a = 640, A = 70°, B = 52° in triangle ABC ; find b. Round answers to the nearest whole number

Answers

Answer: 537

Step-by-step explanation:

Given: a = 640 A =70° B =52°

Whenever two angles and one side of a triangle is given, we can always use the sine formular to find the other side

Using the sine formula;

sin A / a = sin B /b

sin70° / 640 = sin 52° / b

cross multiply

bsin70° = 640sin52°

To get b, we divide bothside by

sin 70°

b = 640sin52° / sin 70°

b = 504. 327 / sin70°

b = 536. 693

b = 537 to the nearest whole number

The first wheel has the numbers 1, 2, and 3.

The second wheel has the letters A and B.

(a) 1 can be followed by A and B, 2 can be followed by A and and B and so is 3.

Possible outcomes = {(1, A), (1, B), (2, A), (2, B), (3, A), (3, B)}

Answers

No more means less or equal.
if number of books is x,
then
x≤8.

It says "No more than 8 books are in your bag". Here "Not more than" a specific number would be a set of all values that are "less than or equal" to given number.

So let's consider 'n' represents the number of books in the bag and we know this number can not be a negative value i.e. n is "greater than or equal" to 0.

Also n is "less than or equal" to 8 as given in the question.

Hence, the inequality would be 0 ≤ n ≤ 8.

where in this case

Therefore, statement I is true. This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of

Since

95 = 1.8, statement II is true.

The only answer that has both statement I and statement II as true is D, but if you have time and want to be absolutely thorough, you can also check to see if statement III (an increase of
