Answer:21.98

Step-by-step explanation:

It is because the formula for the circumference of a circle is 2 x 3.14 x r so I do the 2 x 3.14 and I get the 6.28 and then 6.28 x 3.5(radius) is 21.98.

Answer:

Here we have two triangle rectangles, and we want to know the value of y, the shared cathetus between them.

First, we know that one of them has an angle of 60° and the adjacent cathetus to it is a.

The other has an angle of 30° and the adjacent cathetus is b.

In both cases, the opposite cathetus is y.

Now we can recall the relationship:

Tan(a) = (opposite cathetus)/(adjacent cathetus)

Then we can write:

tan(60°) = y/a

tan(30°) = y/b

And we also know that:

a + b = 15

Then we have 3 equations:

tan(60°) = y/a

tan(30°) = y/b

a + b = 15

To solve this, we first need to isolate one variable in one of the equations, i will isolate a in the third equation:

a = 15 - b

Now we can replace it in the first equation to get:

tan(60°) = y/(15 - b)

i will rewrite this one as:

tan(60°)*(15 - b) = y

then our system is:

tan(60°)*(15 - b) = y

tan(30°) = y/b

now we can isolate b in the second equation to get:

b = y/tan(30°)

and then replace it on the other equation to get:

tan(60°)*(15 - y/tan(30°)) = y

Now we can remember that:

tan(60°) = √3

tan(30°) = (√3)/3

Replacing these in our equation we get:

√3*(15 - y/((√3)/3)) = y

we can rewrite this as:

√3*(15 - y*3/√3) = y

then:

(√3)*15 - y*3 = y

(√3)*15 = y + y*3

(√3)*15 = 4*y

(√3)*15/4 = y

then we get:

[tex]y = \frac{15}{4} *\sqrt{3}[/tex]

Answer:

x = 13

y = 18.38

Step-by-step explanation:

tan 45 = x/13       (tangent = opposite / adjacent)

1 = x/13

multiply both sides by 13

x = 13

cos 45 = 13/y       (cosine = adjacent / hypotenuse

0.7071 = 13/y

multiply both side by y

0.7071y = 13

divide both side by 0.7071

y = 18.38

Answer:

Step-by-step explanation:

Let the exponential function given in the picture is,

f(x) = a(b)ˣ

Here, a = Initial value

b = Base value

x = Exponent

Since, the graph passes through the points (0, 1) and (1, 3)

For (0, 1),

1 = a(b)⁰

a = 1

For (1, 3),

3 = 1(b)¹

b = 3

Therefore, equation of the given function will be,

f(x) = (3)ˣ

Therefore, Initial value = 1

Base = 3

Asymptote (Horizontal) → y = 0

Vertical asymptote → None

Domain → (-∞, ∞) Or {x | x ∈ R}

Range → (0, ∞) Or {y | y > 0}

Therefore, answers given by Juan are incorrect.

Answer:

27.

Step-by-step explanation:

9 / 1/3

= 9 * 3/1

= 9 * 3

= 27.

Exact Form: 28 /3

Decimal Form: 9.  333

First keep the denominator how it is.

To get the the numerator multiply the 9 by the denominator which is 3 so you will get 27. Then add the numerator which is 1 to 27 so you will get 28.

So the answer is 28/3 in exact form. To convert it to decimal form you just multiply 28 by 3.

Answer:

Step-by-step explanation:

Mason's straight-time pay for working 40 hours last week was $706.00.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Mason earns $17.65 per hour and he worked 40 hours last week.

To find his straight-time pay, we need to multiply his hourly rate by the number of hours he worked:

Straight time pay = Hourly rate × Number of hours worked

Straight time pay = $17.65/hour × 40 hours

Straight time pay = $706.00

Therefore,

Mason's straight-time pay for working 40 hours last week was $706.00.

Answer:

13.3 = t

31.3= s

Step-by-step explanation:

Remember that sinθ = [tex]\frac{opposite}{hypotenuse}[/tex], cosθ = [tex]\frac{adjacent}{hypotenuse}[/tex], and tanθ = [tex]\frac{opposite}{adjacent}[/tex]. (A good mnemonic to remember this is SOH-CAH-TOA).

Knowing this is true, we can solve for t and s.

sin(23°) = [tex]\frac{t}{34}[/tex]

34sin(23°) = t

13.3 = t

cos(23°) = [tex]\frac{s}{34}[/tex]

34cos(23°) = s

31.3= s

Ellen's state income tax rate is 0%. So she only owes the city tax of $1,071.75.

What are tax credits?

Tax credits are a type of tax incentive that reduce the amount of tax owed by an individual or business. They are different from tax deductions, which reduce taxable income before calculating the amount of tax owed.

To calculate Ellen's total state and city income tax, we need to first find out how much city tax she owes, and then add that to her state income tax.

Ellen's taxable income is $42,870. To find out how much city tax she owes, we can multiply her taxable income by the city tax rate of 2.5%:

City tax = 0.025 x $42,870 = $1,071.75

So Ellen owes $1,071.75 in city tax.

To find out her total state and city income tax, we need to add the city tax to her state income tax. We don't have any information about her state income tax rate, so we can't calculate that directly. But we can use the fact that her total tax rate (including both state and city tax) is 2.5% to set up an equation:

Total tax rate = state tax rate + city tax rate

0.025 = state tax rate + 0.025

Solving for the state tax rate, we get:

state tax rate = 0.025 - 0.025 = 0

This means that Ellen's state income tax rate is 0%. So she only owes the city tax of $1,071.75.

Therefore, Ellen's total state and city income tax is $1,071.75.
