Answer 1

Answer:

x = 18

m∠HCB = 36

Step-by-step explanation:

The measure of angle FBC is 8x and the measure of angle HCB is 2x. If you add the measures of both angles it will equal to 180 degrees. This can be represented in an equation:

8x + 2x = 180

10x = 180

Divide both sides of the equation by 10 to isolate the x:

10x/10 = 180/10

x = 18

Now that we know the value of x, we can find the measure of angle HCB:

2(18)

The measure of angle HCB is 36.

B.)f( x) = x + 2
C.)f( x) = - x + 2

Answers

Answer:

Step-by-step explanation:

Looking at the graph, we can see that the graph crosses the y-axis at y=2.

Hence, our y-intercept should be 2.

Therefore, we can eliminate A.

We also notice that the graph is downwards sloping.

Therefore, our slope is negative.

So, we can eliminate B.

Therefore, our answer must be C.

What is the image of (-3, -3) after a dilation by a scale factor of 1/3 centered at the
origin?

Answers

The image of (-3, -3) after dilation by a scale factor of 1/3 centered at the origin is (-1, -1).

What are transformations?

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

Given, the image of (-3, -3) after dilation by a scale factor of 1/3 centered at the origin will be,

= (-3/3, -3/3).

= (-1, -1).

It has been shrinked by a factor of three the image became smaller.

A savings bond currently made Jamar $2,112.64 worth of interest in 7 years. If the investment gained 5.5% annual simple interest each year, approximately how much was the bond originally bought for?

A.$1381.81
B.$2673.21
c.$4903.23
D.$5487.36

Answers

Answer:

D; it was bought for $5,487.36

Step-by-step explanation:

Let the investment amount be $x

We use the formula for simple interest to get the interest

(2112.64-x) = (x * 5.5 * 7)/100

211264-100x = 38.5x

138.5x = 211264

x = 211264/138.5

x = 5,847.36

Answers

Answer:

Step-by-step explanation:

Are there any choices?

2(4x+1)

8x+2

The expression equivalent of 2(4x+1) would be; 8x+2

What are equivalent expressions?

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need to find the expression into an equivalent.

Therefore, given expression is

2(4x+1)

This expression could also be given by;

2(4x+1) = 2(4x ) + 2

Now, we know that:

2(4x+1) = 8x+2

Hence, the expression equivalent of 2(4x+1) would be; 8x+2

How many moles are in the 500.0g lump of coal (which is made of carbon) that you received in your Christmas stocking last year?
How many carbon atoms are in this 500.0g lump of coal?

Answers

Answer:

Number of moles = 41.67 (Approx)

Number of carbon atom = 250.97 x 10²³ (Approx)

Step-by-step explanation:

Given:

Amount of carbon = 500 g

Find:

Number of moles

Number of carbon atom

Computation:

Number of moles = 500 / Atomic number of weight

Number of moles = 500 / 12

Number of moles = 41.67 (Approx)

Number of carbon atom = Number of moles x Avogadro number

Number of carbon atom = 41.67 x 6.023 x 10²³

Number of carbon atom = 250.97 x 10²³ (Approx)

b. What percent of the purchase price would a $12,000 down payment be?

Answers

Answer:

A) 4%

B) 20%

The price of pears can be determined by the equation P=0.54n, where P is the price and n is the number of pears. What is the constant of proportionality (unit rate)?

PLEASE NEED THIS ASAP!!!!!!!!!!

Answers

Answer:

The constant of proportionality is 0.54

Step-by-step explanation:

Given:

P = 0.54n

Where,

P = price of pears

n = number of pears

What is the constant of proportionality (unit rate)?

The constant of proportionality is 0.54

This means a unit of pears cost $0.54

If the number of pears bought, n = 50

Then,

P = 0.54n

When n = 50

P = 0.54(50)

= 27

P = 27 when n = 50

The correct answer is:

The constant of proportionality is 0.54

A swimming pool is 30 feet wide and 50 feet long. If it is surrounded by square tiles, each of which is 1 foot by 1 foot, how many tiles are there surrounding the pool?

Answers

Answer:

164 tiles

Step-by-step explanation:

Per the above details, we will require tiles along all the sides of the swimming pool ,hence the circumference of the pool is denoted as;

= 2(wide + long)

Wide = 30 feet

Long = 50 feet

Circumference = 2(30 + 50)

Circumference = 2(80)

Circumference = 160.

It means that minimum of 160 tiles of 1 ft length is required, however, we will also require tile on each of the corners(4), total equals

= 160 + 4

= 164 tiles

A total of 164 tiles are there surrounding the pool.
