Daniel bought a bicycle for $80 and a helmet for $20. The sales tax was 5%. How much did Daniel pay for the two items, including tax?

Answers

Given:

Daniel bought a bicycle for $80 and a helmet for $20.

Sales tax = 5%

To find:

The total amount of both items including tax.

Solution:

Price of bicycle (excluding tax)= [tex]\$80[/tex]

Price of helmet(excluding tax) = [tex]\$20[/tex]

Price of both items = [tex]\$80 + \$20[/tex]

                                =[tex]\$100[/tex]

Now, the sales tax is 5%. So,

Price of both items (including tax) = [tex]\$100+\dfrac{5}{100}(\$100)[/tex]

                                                        = [tex]\$100+\$5[/tex]

                                                        = [tex]\$105[/tex]

Therefore, the Daniel pays $105 for the two items, including tax.

What is the length of bc in the right triangle?

Answers

Answer:

D.39

Step-by-step explanation:

Pythagorean Theorem: a^2+b^2=c^2 (Where a and b are the legs of the triangle and c is the hypotenuse)

Using this:

(AB)^2+(AC)^2=(BC)^2 (Pythagorean theorem)

15^2+36^2=(BC)^2 (Substitution)

225+1296=(BC)^2

(BC)^2=1521

BC=39

Answer:

D. 39

Step-by-step explanation:

The three interior angles of a right triangle always have a sum of 180°, and right angles always equal 90°.

Adding the angles shown here,

36+15+90 = 141

And, 180 - 141 = 39°.

Therefore, the length of angle BC is 39°.

Q5:

Surface area of a cube = 6a²

a = 6 cm

Plug in the value of a

Surface area of the cube = 6(6²)

= 6(36)

S.A = 216 cm²

Q6:

Given:

Length (L) = 9 cm

Width (W) = 4 cm

Height (H) = 7 cm

Surface area

Solution:

Surface area of the rectangular prism = 2(LW + LH + HW)

Plug in the values

S.A = 2(9*4 + 9*7 + 7*4)

= 2(36 + 63 + 28)

= 2(127)

S.A = 254 cm²

Which transformations are needed to change the parent cosine function to y = 3 cosine (10 (x minus pi))?

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

New function: [tex]y = 3 \cos(10 (x -\pi))[/tex]

We can assume the parent function to be:

[tex]y = \cos (x)[/tex]

The new function can be represented as:

[tex]y = A*\cos((\frac{2\pi}{B})(x-c))[/tex]

Where

A = Vertical stretch factor

B = Period

C = Right shift

By comparison:

[tex]y = A*\cos((\frac{2\pi}{B})(x-c))[/tex] to [tex]y = 3 \cos(10 (x -\pi))[/tex]

[tex]A = 3[/tex]

[tex]c = \pi[/tex]

[tex]\frac{2\pi}{B} = 10[/tex]

Solve for B

[tex]B = \frac{2\pi}{10}[/tex]

[tex]B = \frac{\pi}{5}[/tex]

Using the calculated values of [tex]A,\ B\ and\ c.[/tex] This implies that, the following transformations occur on the parent function:

If θ is an angle in standard position and its terminal side passes through the point (-7,-5), find the exact value of cot ⁡ θ cotθ in simplest radical form.

Answers

Plot the point (-7, -5). We are in quadrant 3.

We also know that tan θ = opp/adj.

Cot θ = adj/opp.

Let us use a^2 + b^2 = r^2 to show you how to find r, the radius aka hypotenuse.

Look: (-7)^2 + (-5)^2 = r^2

If you should ever need to find r, do this:

(-7)^2 + (-5)^2 = r^2

(49) + 25) = r^2

74 = r^2

Take the square root on both sides of the equation to find r.

sqrt{74} = sqrt{r^2}

sqrt{74} = r

It is ok to simplify the sqrt{74} but not needed.

We now have the three sides of the triangle that is form in quadrant 3.

We can now read cot θ from the triangle itself.

So, cot θ = adj/opp = (-7)/(-5) or 7/5.

No need to find r but I simply wanted to show you how it's done in case you are given a question where r must be found.

Please help ASAP!!!!!!!!!

A local school board wants to determine if the proportion of households in the district that would support starting the school year a week earlier has changed from the previous year. Last year, the school board determined that 65% of households supported starting school earlier. They ask a random sample of 100 households this year, and 70% state they would support starting the school year earlier. Which hypotheses would determine if the proportion of households that support starting school earlier has changed this year?
Group of answer choices

H 0: p not-equals 0.70, H alpha: p = 0.70

H 0: p = 0.70, H alpha: p not-equals 0.70

H 0: p = 0.65, H alpha: p greater-than 0.65

H 0: p = 0.65, H alpha: p not-equals 0.65

Answers

Answer:

C

Step-by-step explanation:

Considering the situation, the hypotheses set that would determine if the proportion of households that support starting school earlier has changed this year is given by:

[tex]H_0: p = 0.65, H_\alpha: p \neq 0.65[/tex]

What are the hypotheses tested?

At the null hypotheses, it is tested if there has been no change, that is, the proportion is still of 0.65 = 65%, hence:

[tex]H_0: p = 0.65[/tex]

At the alternative hypotheses, it is tested if there has been a change, that is, the proportion is not of 0.65 = 65% anymore, hence:

[tex]H_\alpha: p \neq 0.65[/tex]

a circle has a radius of sqrt37 units and is centered at 1.3,-3.5

Answers

Answer:

80

Step-by-step explanation:

Answer:

(x-1.3)^2 + (y+3.5)^2 = 37

In general, (x-c)^2 + (y-k)^2 = r^2 where (c,k) is the center and r is the radius.

So if the circle with radius 5 has center (3,-4) then it's equation is:

(x-3)^2 + (y+4)^2 = 25

Notice that the second term is (y+4)^2 because the y-coordinate is -4 and y-(-4) = y+4

Answers

Answer:

1. x = 58

2. x = 44

Step-by-step explanation:

#1:

2x + 5 + x + 2x + 7 + x = 360

Step 1: Combine 2x, x, 2x, and x to get 6x.

6x + 5 + 7 = 360

Step 2: Add 5 & 7 to get 12.

6x + 12 = 360

Step 3: Subtract 12 from both sides

6x = 360 - 12

6x = 348

Step 4: Divide both sides by 6.

x = 348/6

x = 58

#2:

3x + 2 + 2x + 2x + 1 + x + 5 = 360

Step 1: Combine like terms.

8x + 2 + 1 + 5 = 360

8x + 8 = 360

Step 2: Subtract 8 from both sides.

8x = 360 - 8

8x = 352

Step 3: Divide both sides by 8.

x = 352/8

x = 44
