Answer:

13. [tex]C=6\pi[/tex]

14. [tex]C=9\pi[/tex]

15. [tex]C=7\pi[/tex]

Step-by-step explanation:

To find the circumference of a circle, the formula is [tex]C=2\pi r[/tex], with "C" being the circumference and "r" being the radius.

In question 13, the radius (r) is shown as 3ft. When you put this into the equation, it should look like this:

[tex]C=2\pi (3)[/tex]

Simplify.

[tex]C=6\pi[/tex]

Follow the same steps in questions 14 and 15. In 14, 9 is the diameter, which makes the radius 4.5.

The final answers are shown above.

Answer:

25/12

Step-by-step explanation:

1/2+3/4

You have to find a common denominator so you multiply 2 to 1/2 which gives you 2/4 so now you add 2/4+3/4 which gives you 5/4. You don't add the denominators.

Next you have to add 5/4+5/6. Again, you have to find a common denominator. since 3*4 is 12 and 2*6 is also 12 then you multiply them. You should end up with 15/12+10/12. 15+10 is 25 so your answer is 25/12.

The equations that are direct variation functions are;

y = x and y = ¹/₄x + 2

Direct Variation function is defined as the function where two quantities vary directly i.e. variables x and y are said to be directly varying if y = kx. Where;

k is the constant of variation.

here, we have ,

to Solve Variation:

Direct Variation function is defined as the function where two quantities vary directly i.e. variables x and y are said to be directly varying if y = kx. Where;

k is the constant of variation.

Thus, from the options, we see that the function,

y = x varies directly with the constant of variation i.e. k = 1.

Similarly, y = ¹/₄x + 2 is also varying directly with constant k=1

Hence, The equations that are direct variation functions are;

y = x and y = ¹/₄x + 2

2. 1 painting takes 4 days

Step-by-step explanation:

Answer:

x = 3.38

y = 9.24

z = 8

Step-by-step explanation:

first: solve for the vertical length

8√2² = 2z²

128 = 2z²

z² = 64

z = 8

vertical height = 8 also because z is one side of a square

tan 60 = z/a = 8/a

a = 4.62

x = 8 - 4.62 = 3.38

sin 60 = z/y = 8/y

y = 9.24

Answer and Step-by-step explanation:

Use Pythagorean  Theorem for 6 and 9.

6.

[tex]8^{2} + w^{2} = 14^{2} \\\\\\w^{2} = 132\\\\\\2\sqrt{33} = w = 11.49[/tex]

7. Use Cosine, and then Tangent.

[tex]cos(30) = \frac{15}{y} \\\\y = \frac{15}{cos(30)\\\\}\\\\y = 10\sqrt{3}, or 17.32[/tex]

[tex]tan(30) = \frac{x}{15} \\\\15tan(30) = x\\\\5\sqrt{3} = x = 8.66[/tex]

8. Use Sine.

[tex]sin(theta) = \frac{23}{42} \\\\theta = sin^{-1} (\frac{23}{42} )\\\\theta = 33.2[/tex]

9.

y = 7

[tex]7^{2} +7^{2} = x^{2} \\\\98 = x^{2} \\\\7\sqrt{2} = x = 9.9[/tex]

Step-by-step explanation:

sammy already had 13 andellie gave her enough to make her have 21. so 13 plus 8 = 21. so d = 8

Answer:

No.  The correct answer is x = 4i.  The mistake is made on the penultimate step where "Mark" squares both sides, eliminating the negative sign.

Step-by-step explanation:

We can see that the answer is incorrect, because if we plug it back into the original equation, we get:

[tex]8 - \sqrt{x} = 10\\8 - \sqrt{4} = 10\\8 - 2 = 10\\6 = 10[/tex]

This of course is obviously incorrect.  The mistake is made in squaring away the negative sign in solving the problem.  An easier way to look at this is to get rid of √x, and substitute it for "n", and see what we get:

[tex]8 - n = 10\\-8 + n = -10\\n = -2[/tex]

If we swap √x back in, we get:

√x = -2

x = 4i

let's solve it correctly:

[tex]8 - \sqrt{x} = 10\\-\sqrt{x} = 10 - 8\\-\sqrt{x} = 2\\\sqrt{x} = -2\\x = 4i[/tex]

Answer:

0.25

Step-by-step explanation:

1 divided by 4 = 0.25

The value of the rational number rounded to the nearest hundredths is given by A = 0.25

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Non-zero digits are always significant

Zeros between non-zero digits are always significant

Leading zeros are never significant

Trailing zeros are only significant if the number contains a decimal point

Given data ,

Let the rational number be represented as A

Now , the value of A is

A = ( 1/4 )   be equation (1)

On simplifying , we get

The value of 1 divided by 4 is 25 %

So , A = 0.25

On rounding the number 0.25 to the nearest hundredths , we get

A = 0.25

Therefore , the value of A is 0.25

Hence , the rounded number is A = 0.25

Answer:

B.  [tex]x = -4\,\lor \,x = -1[/tex]

Step-by-step explanation:

Let [tex]\sqrt{-4-5\cdot x} = x[/tex], we solve for [tex]x[/tex] by algebraic means.

1) [tex]\sqrt{-4-5\cdot x} = x[/tex] Given

2) [tex]-4-5\cdot x = x^{2}[/tex] Definition of power/Symmetry of equality

3) [tex]x^{2}+5\cdot x + 4 = 0[/tex] Compatibility with addition/Commutative and associative properties/Existence of additive inverse/Modulative property

4) [tex](x+4)\cdot (x+1) = 0[/tex]         [tex]x^{2}+(a+b)\cdot x +a\cdot b = (x + a)\cdot (x+b)[/tex]

5) [tex]x = -4\,\lor \,x = -1[/tex] Result

Hence, the correct answer is B.

Answer:

A=300(1+0.035)^t

A=300(1+0.035)^7 = $381.70

A=300(1+0.035)^21 = $617.83

Step-by-step explanation:

It's pretty simple. Use the formula that I posted in the answer. And 1 will always be 1. The decimal comes from the percent. Remember to bring it two places to the left to make a fraction into decimal form. And the t is years. So you raise it to the power of how many years.
