Answer:

C

Step-by-step explanation:

You can use process of elimination. In D and A all the y numbers are staying the same. In B, the numbers are decreasing. So the only possible answer is C.

Answer:

The answer is 1/5

Step-by-step explanation:

The answer is 1/5

Answer:

50

Step-by-step explanation:

the equation is 700-4x=500

A) x = 15

steps:

90 = 5x + 15

-15 -15

75 = 5x

÷5 ÷5

15 = x

explanation:

< P is 90°

so you have the equation of < P equal 90 to find the x

B) < RQP = 33

steps:

2x + 3

2(15) + 3

30 + 3

33

explanation:

now that you know what x equals you just plug in 15 for the x and solve

Answer:

see explanation

Step-by-step explanation:

(a)

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles from 180° for B

∠ B = 180° - (90 + 63)° = 180° - 153° = 27°

(b)

Using the sine ratio in the right triangle

sin63° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{15}{x}[/tex] ( multiply both sides by x )

x × sin63° = 15 ( divide both sides by sin63° )

x = [tex]\frac{15}{sin63}[/tex] ≈ 16.8 ( to 1 dec. place )

(c)

Using the tangent ratio in the right triangle

tan63° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{15}{y}[/tex] ( multiply both sides by y )

y × tan63° = 15 ( divide both sides by tan63° )

y = [tex]\frac{15}{tan63}[/tex] ≈ 7.6 ( to 1 dec. place )

Answer:

A. [tex] \frac{48}{20} [/tex]

Step-by-step explanation:

The figure is a rectangular prism.

Volume of a rectangular prism = Length*Width*Height

Length = 12

Width = ¼

Height = ⅘

Plug in the values into the volume formula

[tex] V = 12 * \frac{1}{4} * \frac{4}{5} [/tex]

[tex] V = \frac{12*1*4}{4*5} [/tex]

[tex] V = \frac{48}{20} [/tex]

Answer:

B. 720 ways

Step-by-step explanation:

To solve you would multiple 6x5x4x3x2x1 .

The required number of ways can 6 players be assigned to 6 positions on a baseball team is 720ways.

Given that,

Number of players = 6

Assigned position on a baseball = 6

We have to determine,

In how many ways can 6 players be assigned to 6 positions on a baseball team.

According to the question,

To solve this problem assuming that any player can play any position.

The formula to find [tex]^nP_r[/tex] is given by:

[tex]^np_r[/tex] is the permutation of arrangement of 'r' objects from a set of 'n' objects, into an order or sequence.

The formula to find permutation is:

[tex]^np_r = \frac{n!}{(n-r)!}[/tex]

Where, n = 6 and r = 6

Therefore,

[tex]^6p_6 = \frac{6!}{(6-6)!} \\[/tex]

     [tex]= \frac{6\times5\times 4 \times 3 \times 2 \times 1}{0!} \\\\= \frac{720}{1} \\\\= 720 \ ways[/tex]

Hence, The required number of ways can 6 players be assigned to 6 positions on a baseball team is 720ways.

Given:

A diagram of a composite figure.

Radius of cone and hemisphere is 8 cm.

Height of the cone is 15 cm.

To find:

The volume and the surface area of the composite figure.

Solution:

Volume of a cone is:

[tex]V_1=\dfrac{1}{3}\pi r^2h[/tex]

Where, r is the radius and h is the height of the cone.

Putting [tex]r=8,h=15[/tex] in the above formula, we get

[tex]V_1=\dfrac{1}{3}\pi (8)^2(15)[/tex]

[tex]V_1=\pi (64)(5)[/tex]

[tex]V_1=320\pi[/tex]

Volume of the hemisphere is:

[tex]V_2=\dfrac{2}{3}\pi r^3[/tex]

Where, r is the radius.

Putting [tex]r=8[/tex], we get

[tex]V_2=\dfrac{2}{3}\pi (8)^3[/tex]

[tex]V_2=\dfrac{1024}{3}\pi [/tex]

[tex]V_2\approx 341.3\pi [/tex]

Now, the volume of the composite figure is:

[tex]V=V_1+V_2[/tex]

[tex]V=320\pi +341.3\pi[/tex]

[tex]V=661.3\pi[/tex]

The volume of the composite figure is 661.3π cm³.

The curved surface area of a cone is:

[tex]A_1=\pi r\sqrt{h^2+r^2}[/tex]

Where, r is the radius and h is the height of the cone.

Putting [tex]r=8,h=15[/tex] in the above formula, we get

[tex]A_1=\pi (8)\sqrt{(15)^2+(8)^2}[/tex]

[tex]A_1=\pi (8)\sqrt{289}[/tex]

[tex]A_1=\pi (8)(17)[/tex]

[tex]A_1=136 \pi [/tex]

The curved surface area of the hemisphere is:

[tex]A_2=2\pi r^2[/tex]

Where, r is the radius.

Putting [tex]r=8[/tex], we get

[tex]A_2=2\pi (8)^2[/tex]

[tex]A_2=2\pi (64)[/tex]

[tex]A_2=128\pi [/tex]

Total surface area of the composite figure is:

[tex]A=A_1+A_2[/tex]

[tex]A=136\pi +128\pi[/tex]

[tex]A=264\pi[/tex]

The total surface area of the composite figure is 264π cm².

Therefore, the correct option is A.

Answer:

the daily periodic rate is 0.0411%

Step-by-step explanation:

Given that

The Annual percentage rate is 14.99%

We need to find out the daily periodic rate for the credit card

As we know that

Daily periodic rate = annual percentage rate ÷ 365 days

= 14.99%  ÷ 365  days

= 0.0411%

Hence, the daily periodic rate is 0.0411%

Answer:

x=15

Step-by-step explanation:

So we know 4x plus 8x gets a total of 180 degrees (since a straight line is 180 degrees). Combine 4x and 8x to get 12x. To find x, divide 12 from 180. 180/12 is 15.

Read this passage from "The American Dream."

One of the first things we notice in this dream is an amazing universalism. It does not say some men, but it says all men. It does not say all white men, but it says all men, which includes black men. It does not say all Gentiles, but it says all men, which includes Jews. It does not say all Protestants, but it says all men, which includes Catholics.

How does the use of rhythm contribute to the ideas in the passage?

It supports key points by connecting them.

It states rational ideas to support a claim.

It convinces people that the ideas are true.

It connects the ideas to people in a specific place.
