By simplifying  45y/30y (7x+49)  this  we get 3 / 2(7x + 49).

45y/30y (7x+49)

45y / 30y(7x +49) : 3 / 2(7x + 49)

45y / 30y(7x + 49)

45y / 30(7x + 49)

Factor the number :45 = 15 . 3

=15.3 / 30(7x + 49)

Step-by-step explanation: 600/20=30 so each inch on the scale represents 30 feet in real life.

You may not cross a single broken white or yellow line, when doing so would interfere with traffic unless it is safe to do so and without interfering with traffic.  

The yellow line on the road serves as a barrier between opposing lanes of traffic as a traffic safety measure. It is intended to alert drivers to the fact that they are moving in the opposite directions and should keep a safe distance while driving.

The yellow line is typically placed in the centre of the road to indicate the separation of traffic. On highways and interstates, the yellow line is frequently used to mark the separation between two lanes of traffic moving in the same direction.

Drivers should always follow the yellow line and never cross it because doing so can be risky and result in accidents. The yellow line can also be used to show when passing other vehicles is dangerous.

On the driver's side, it is prohibited to pass other cars when a yellow line is interrupted by a solid line. Overall, the yellow line is an important safety measure for drivers to be aware of and obey when on the road.

Answer: The front row has 4 fixed seats (s1, s2, s3, s4) and 5 open seats. The back row has 6 fixed seats (s5, s6, s7, s8, s9, s10) and 3 open seats. The remaining students (s11, s12, s13, s14, s15) can be placed in the open seats in the front row or the open seats in the back row in any combination.

The open seats in the front row can be filled by the remaining 5 students in 5! ways.

The open seats in the back row can be filled by the remaining 5 students in 5! ways.

So the total number of ways the students can be seated is (5!)^2 = 54321 * 54321 = 14400

Step-by-step explanation:

Heath had the longest jump of 6 meters in the competition.

Comparison theory is a psychological theory that proposes that people use social comparisons to better understand their own value and place in society. According to this hypothesis, people compare themselves to others in order to assess themselves, typically focusing on the traits that they have and the qualities that other people have. Individuals utilise the comparison to estimate their own value and how they should conduct in order to achieve approval and acceptance from their peers.

This question requires the use of the Comparison Theory.

This theory states that when presented with two or more items, we can compare them to determine which is larger, smaller, longer, shorter, etc.

In this case, we need to compare the distances of each jump for each teammate in order to determine which one had the longest jump.

Step 1: Look at the distances of each jump for Heath.

Step 2: Look at the distances of each jump for Amari.

Step 3: Compare the distances of each jump for both Heath and Amari.

Step 4: Determine which jump was the longest - Heath's 6 meter jump.

Answer: A function that increases by a factor of 10 over every unit interval in x and starts at f(0)=1 could be represented by the function rule f(x) = 10^x.

This function starts at f(0) = 10^0 = 1 and for every increase of 1 in the input x, the output f(x) increases by a factor of 10. For example:

f(1) = 10^1 = 10

f(2) = 10^2 = 100

f(3) = 10^3 = 1000

and so on.

Another possible function rule could be f(x) = 10x +1 it starts at f(0) = 1 and for every increase of 1 in the input x, the output f(x) increases by a factor of 10. for example:

f(1) = 101 +1 = 11

f(2) = 102 +1 = 21

f(3) = 103 +1 = 31

and so on.

Both functions have similar behavior and answer the given conditions.

A quadratic equation of the form ax^2 + bx + c = 0 has solutions (or roots) that are either real or complex. The solutions of the equation vanish (or become equal to zero) when the equation is equal to zero.

For the equation x^2 (2p-4)x-(3q5)=0 to have a solution that vanishes, the discriminant (b^2 - 4ac) must be equal to zero.

Therefore, the roots of the quadratic equation x^2 (2p-4)x-(3q5)=0 vanish when p = 4 and q = 0

Yes I can receive the radio signals.

The value of x  when y = 10 and Z = 16, in the given joint variation is: 1120.

If X varies jointly with Y and Z, then we can use the formula X = k * Y * Z, where k is the constant of proportionality.

Using the given information, we can find k by plugging in the values of Y, Z, and X and solving for k:

14 = k * 2 * 4

k = 14 / (2 * 4)

k = 7/2

Now that we know the value of k, we can use it to find the value of X when Y = 10 and Z = 16:

X = k * Y * Z

X = (7/2) * 10 * 16

X = 70 * 16

X = 1120

So the value of X when Y = 10 and Z = 16 is 1120.

Flag is triangular in shape.

Base of the flag = 3.5 feet

Height of the flag = 2.5feet

Area of the flag = ( 1/2) base × height

The ratio of their shares is 1:2:3 and amount is 180.5, 3564, 5371.5 respectively.

To find the amount each received:

Atta received 13.5*(51+110) = 1807.5

Abena received 27*(51+110) = 3564

Kojo received 40.5*(51+110) = 5371.5

The total amount shared is 51 + 110 = 161

The ratio of their shares is 1:2:3, meaning Atta receives 1/6 of the total amount, Abena receives 2/6 of the total amount, and Kojo receives 3/6 of the total amount.

To find the amount each received, we multiply their respective share (1/6, 2/6, and 3/6) by the total amount (161)

Kojo received 3 times as much as Atta, and Atta received 1/2 times as much as Abena.

Atta received 1/6 of the total amount, which is (51 + 110)/6 = 81/6 = 13.5

Abena received 2/6 of the total amount, which is (51 + 110)*2/6 = 162/6 = 27

For the graph with points (-2, 2) and (2,0), the slope, linear equation and y-intercept is m = -1/2, y = -1/2x + 1 and y = 1 respectively.

What is a linear equation?

A linear equation is one that has a degree of 1 as its maximum value. No variable in a linear equation, thus, has an exponent greater than 1. A linear equation's graph will always be a straight line.

The first graph shows the points (-2, 2) and (2,0).

The slope-intercept form of an equation/function is - y = mx + b

To find the slope m use the formula -

(y2 - y1)/(x2 - x1)

Substituting the values in the equation -

[0 - 2]/[2 - (-2)]

(-2)/(2 + 2)

-2/4

-1/2

So, the slope point is obtained as m = -1/2.

The equation becomes - y = -1/2x + b

To find the value of b substitute the values of x and y in the equation -

2 = -1/2(-2) + b

2 = 1 + b

b = 2 - 1

b = 1

So, the value for b is 1.

Now, the equation becomes -

y = -1/2x + 1

To find the y-intercept substitute the value of x = 0 in the equation -

y = -1/2(0) + 1

y = 0 + 1

y = 1

Therefore, the slope is 1, equation is y = -1/2x + 1 and y-intercept is y = 1.

There are 6 possible outcomes for this experiment.

The total number of outcomes possible for an experiment of drawing two balls one after the other without replacing the first ball, depends on the number of possible outcomes for the first draw, multiplied by the number of possible outcomes for the second draw, given that the first ball was not replaced.

The total number of ways to choose one ball out of three is 3, and the number of ways to choose the second ball out of two remaining balls is 2. Therefore, the total number of outcomes possible for this experiment is 3 x 2 = 6.

After applying the sales tax, the expression for the total price of the phone is 1.03p.

What is sales tax?

The government levies a consumption tax known as a sales tax on the purchase of goods and services. At the point of sale, a standard sales tax is imposed, collected by the shop, and paid to the government.

The amount for phone is represented as - p dollars and cents

The sales tax percentage is - 3% = 0.03

The sales tax applied on the phone is - 0.03p

The total price of the phone is denoted by the expression -

Total Price = Price of phone + Sales Tax

Total Price = p + 0.03p
