WHy is an assingment so hard or at least why do they make it difficult

Answer/Step-by-step explanation:

The equation, [tex] \frac{20}{x} = -5 [/tex] has one solution, x.

The value of x that will make the equation true, that is the number we can substitute for x into the equation that will make what we have on our left side equal to what we have on our right side is -4.

Substitute -4 for x in the equation and simplify:

[tex] \frac{20}{-4} = -5 [/tex].

Simplifying the equation:

[tex] -5 = -5 [/tex] (this is true).

A value of x that can make the equation false is 4.

Thus, replace x with 4, then simplify.

[tex] \frac{20}{x} = -5 [/tex]

[tex] \frac{20}{4} = -5 [/tex]

[tex] 5 = -5 [/tex] (false. 5 ≠ -5)

Step-by-step explanation:

8.05 * 10^8 - 9.16 * 10^6

= 10^6 * (8.05 * 10^2 - 9.16)

= 10^6 * (805 - 9.16)

= 10^6 * (795.84)

= 10^8 * 7.9584

Therefore the answer in scientific notation is 7.9584 * 10^8.

Answer:

A total of  

360

people were surveyed. Of the people surveyed,  

70

said they were an early bird and preferred tea. The percentage of people surveyed who are night owls is  

60

%. The percentage of early birds who prefer to drink tea is  

49

%.

Step-by-step explanation:

The last row and the last column give the total number of people surveyed, which is 360.

The joint frequency of the Early Bird column and the Tea row show that 70 people said they were an early bird and preferred tea.

To get the percentage of night owls, divide the total number of night owls by the total number of people surveyed and multiply by 100:

To get the percentage of early bird tea drinkers, divide the joint frequency of early birds and tea by the marginal total number of early birds and multiply by 100:

From total of 360 people surveyed, 70 people are early birds and preferred tea. Hence night owls is 60% and people who prefer to drink tea is 49%

A survey is a method of data collection and can be in the form of questionnaires and interviews. The survey tells us about the demands and needs of the people.

As per the question, the last row and column give us a total of 360. Those who are early birds and take tea are 70% of the population. To get the percentage we need to X night owls by the number of people surveyed multiplied by 100.

For the early bird tea, the total frequency of early birds by the marginal total number of early birds multiplied by 100.

Answer:

A

Step-by-step explanation:

Answer: A: (4-g) 1.5

Step-by-step explanation:

Answer:

m∠1 + m∠3 = m∠2 + m∠4

Step-by-step explanation:

In the figure attached,

In the given trapezoid if two sides AB and CD are parallel and AD is a transverse,

m∠1 + m∠3 = 180°

Similarly, if AB and CD are parallel and BC is a transverse,

m∠2 + m∠4 = 180°

Therefore, m∠1 + m∠3 = m∠2 + m∠4 is the relation between these angles.

Answer:

A, B, D, F

Step-by-step explanation:

To determine which of the drawings are well labelled according to their corresponding height (h) for a given base, recall the following:

1. Base of a triangle could be any of the 3 sides of a triangke.

2. Height of a triangle is the perpendicular distance from the corner opposite the base to the base.

3. The height of a triangle could be indicated from outside the triangle.

Going by this 3 criteria, therefore, the following drawings can be said to be well labelled and correctly identifies by their corresponding height with respect to their bases:

Given :

A sequence of numbers consists of natural numbers that are

not perfect squares.

To Find :

The 1000th member of this  sequence .

Solution :

Now , [tex]31^2=961[/tex] and [tex]32^2=1024[/tex] .

So , there are 31 numbers before 1000 which are perfect square .

Therefore , the [tex]999^{th}[/tex] is 1000+31 = 1031 .

Also , the first perfect square after 1000 is 32 .

So , we have to continue to 1031 + 1 = 1032 to compensate for the 32nd square.

Therefore , the 1000th member of this  sequence is 1032 .

Hence , this is the required solution .

The difference between the high and low temperature in the thermometer is 23°F.

Step-by-step explanation:

Given information: Highest temperature = 20°F and the lowest temperature = -3°F.

We need to find the difference between the high and low temperature in the thermometer.

Difference between the high and low temperature is

Difference = Highest temperature - Lowest temperature

Difference = 20°F - (-3°F)

Difference = 20°F + 3°F

Difference = 23°F

Therefore the difference between the high and low temperature in the thermometer is 23°F.

Answer:

A-11

Step-by-step explanation:

Correct on EDGE

The value of the function k(h(10)) will be 11. The correct option is A.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Given h(t) = t²+t+ 12 and k(t) = √t-1, we are to find k(k.h)(10)

k{h(t)} = k{ t²+t+ 12}

Since k(t)= √t-1, we will replace the variable t in the function with t²+t+ 12

k(h(t)) = √{(t²+t+ 12)-1}

k(h(t)) = √t²+t+12-1

k(h(t)) = √t²+t+11

Substituting t = 10 into the resulting function;

k(h(10)) =  √(10)²+(10)+11

k(h(10)) = √100+10+11

k(h(10)) = √121

k(h(10))= 11

Therefore, the value of the function k(h(10)) will be 11. The correct option is A.

Step-by-step explanation:

The property of equality is demonstrated moving from step a to step b is linear.

The linear equation is defined as the equation having a degree of one or the power of the variable will be one. The linear equation is represented by y = mx + c. Here y is the variable, m is the slope and, c is the intercept.

Given that  b = 3, and m = 5, and y = mx + b then, b. y = 5x + 3. The equation can be formed as below:-

y = mx + c

y = 5x + 3

The factors of the given expression are (x + y ) and (a + 3b).

Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

We have been given that expression as :

ax + ay + 3bx + 3by

We have to factorize the given expression.

⇒ ax + ay + 3bx + 3by
