Answer:

35:1

Step-by-step explanation:

divide each by two

Rates compare quantities with different units. 70 students per 2 teachers can be written as 70:2 or 70/2. Unit rate compares two measurements, one being 1, like 55 miles per hour (55 miles/1 hour).

A rate compares two quantities with different units. It is a ratio where one quantity is compared to time, for example, km/h, which compares distance (in kilometers) to time (in hours).

Comparison as a rate in ratio form:

Unit rate: A unit rate is a comparison of two measurements, with one measurement having a value of 1, such as 55 miles per hour (55 miles/1 hour).

Answer:

[tex]y -7 = -\frac{7}{5}(x-5)[/tex]

or

[tex]y = -\frac{7}{5}x +14[/tex]

Step-by-step explanation:

Parallel lines are lines which have the same slope. To write the equation of the line parallel, find the slope of the equation 7x + 5y = 12 through conversion into slope intercept form.

7x + 5y = 12 becomes y = -7/5x + 12/5. The slope is -7/5.

Substitute\ m =-7/5 and the point (5,7) into the slope intercept form.

[tex]y-y_1=m(x-x_1)\\y -7= -\frac{7}{5}(x - 5)[/tex]

Convert the equation to slope intercept form by applying the distributive property.

[tex]y -7 = -\frac{7}{5}(x-5)\\y -7 = -\frac{7}{5}x +7\\y = -\frac{7}{5}x +7+7\\y = -\frac{7}{5}x +14[/tex]

Answer:

Points A and F can be included while keeping the graph a function

Step-by-step explanation:

Graph of a function cannot have two different y-values for a given x-value. This means that at any given point on x-axis only one y value must be available.

So from the given points only those points can be selected, where the function is not already having any y-value.

Point A can be included because at x = - 9, no other y value is defined. So this will keep the given graph as a function.

Point B cannot be added, at at x=-6, the function already has a value which is -4. Adding point B, will result in two values at x = -6 which will be against the definition of function. So point B cannot be added.

Similarly, points C, D and E cannot be added either due to the same reason.

Point F can be added as the graph does not has any value at x = 7. So it will have a unique value here.

Answer:   946 in²

Step-by-step explanation:

Separate the image into 2 sections (left rectangle and right rectangle).

Area of a rectangle = Length (L) × width (w)

Left rectangle: A = 28 × 7

                           = 196

Right rectangle: A = 30 × 25

                              = 750

Area of shape = Area of Left + Area of Right

                        =       196         +       750

                        =                     946

Write the written problem into an equation to get:

3x +2 = 5x -4

To solve:

Add 4 to each side:

3x+6 = 5x

Subtract 3x from each side:

2x = 6

Divide both sides by 2:

x = 6/2

x = 3

You didn't list the options so it could like like any of the equations I show above.

To solve such problems we need to know about expressions.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations that are formed according to rules which are dependent on the context.

The complete equation is 3x+2 = 5x-4 and the value of x is 2.

Given information,

Solution

We can solve the information by dividing the statements into parts,

part A: "The sum of",

Meaning we need to add the two numbers.

part B:  "3 times the value of x",

the first number is 3 times the value of x, therefore, 3x.

part C:  "and 2 is equal to",

the second number is 2. also, "equal" shows that one side of the equation is over and explained.

So, till now we have got

3x + 2

part D:  "4 less than"

meaning 4 is been deducted from a number.

part E: "5 times the value of x",

Now, it is showing us the number from which 4 is been deducted. therefore, the number is 5x.

Thus, the complete equation is 3x+2 = 5x-4.

Further, solving the equation,

[tex]3x+2=5x-2\\+2+2 = 5x-3x\\4 = 2x\\2x =4\\x =2[/tex]

Hence, the value of x is 2.

For the second problem :

We know the total student body so to find a percent of them you just divide the number of students by the total

95 sixth graders

------------------------  = 0.38 which is 38 percent

250 students

45 eighth graders

------------------------------ = 0.18 or 18%

250 students

Now to find the number of students first convert the percent to a decimal then multiply that by the total

24 % = 0.24 times 250

and that equals 60 students

and then 20 percent = 0.2 times 250

and that equals 50 students

If it takes a washer 27.5 minutes for a load and a dryer takes 60% of that time for a load, convert 60% to a decimal (0.6) and multiply by 27.5 → 27.5 * 0.6 = 16.5 which means it takes the dryer 16.5 minutes for a load. To find the total time it takes for a washer and a dryer to complete 1 load, simply add the two times. 27.5 + 16.5 = 44 minutes.

Answer:

Step-by-step explanation:

Don't worry, a lot of people have trouble with this when they first start, i know i did. Anyways, it is fairly simple once you get it. What you can do to get it the easy way is just look at the screen sideways and see if the shapes are the same. If they are (in the way you are looking) find the corner of the angle of the original triangle and look at the moved triangle to see where it matches up. I'm sorry that I don't have a very good way to explain this answer, you are just going to have to pay really close attention. This whole head-spinning thing is tricky, it came to me easy, but i know its hard for some other people. Either way, just look at which way you are rotating the shape, and follow the angle in that direction. Try and follow it in a circle like a clock because when rotating about the origin, if you rotate 360 degrees, you will get back to the original shape.

The statement cos(-x) = -cosx is false becasue cos(-x) = cosx  for all x the statement is false.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

Cos(-x)=-cosx

As we know, cos is the ratio of the side adjacent to the hypotenuse

x ∈ (-∞, ∞)

Take x = -30

cos(-30) = √3/2

cos30 = √3/2

cos(-x) = cosx  for all x

Thus, the statement cos(-x) = -cosx is false becasue cos(-x) = cosx  for all x the statement is false.

Answer:

f and b

Step-by-step explanation:

if you put them in y-intercept form, both slopes are 3

In b. it's easy to see that 3x has a slope of 3.

In f. it's not so obvious. Just solve for y or use the shortcut m = -a/b where a is the coefficient of x and  b is the coeff of y.

hence -(6/-2)=3

Answer:

Step-by-step explanation:

assuming you know how to put the equations into y = m x + b already.  All equations have to be put in that format to identify the slope.  Parallel lines have the same slope.

a.  y = -2x - 1; slope -2

b.  y = 3x - 1; slope 3

c.  y = 2x - 3; slope 2

d.  y = 4x + 3; slope 4

e.  y = x/2 - 1; slope 1/2

f.  y = 3x; slope 3

g.  y = x/3 + 4/3; slope 1/3

h.  y = -x/2 + 5; slope -1/2

There are only 2 that are alike.  b and f both have a slope of 3.  all the other slopes are different.

The teacher being most pleased with the period 1 class suggests they had the highest median score, indicating a better overall performance by the majority in this class.

The statement that would make the teacher most pleased with the exam scores in his period 1 class would be B. The scores for period 1 had the highest median.

This is because the median represents the middle score in a set of scores. If period 1 had the highest median, it means that at least half of the students in this class scored higher than those in his other classes.

In essence, it shows better overall performance by the majority of the class in period 1, which would make a teacher pleased with the results.

This conclusion may not necessarily hold if we choose other options; for example, low Standard Deviation or Interquartile Range (IQR) mainly speak to the consistency of scores, and lowest median would imply most of the class did not perform very well. Hence, the highest median would generally reflect the most favor on the class performance.

The first three terms of the sequence are 6 , 10 , 8 ⇒ 2nd answer

Step-by-step explanation:

* Lets study the rule at first:

- [tex]a_{n}=a_{n-1}-(a_{n-2}-4)[/tex]

∴ [tex]a_{n}=a_{n-1}-a_{n-2}+4[/tex]

* That means to find a term add the difference between

  the two consecutive term before it to 4.

* lets start with [tex]a_{6}=a_{5}-a_{4}+4[/tex]

∵ [tex]a_{5}=-2,a_{6}=0[/tex]

∴ [tex]0=-2 -a_{4}+4[/tex]

∴ [tex]0=2-a_{4}[/tex]

∴ [tex]a_{4}=2[/tex]

* Use [tex]a_{5}[/tex] to find [tex]a_{3}[/tex]

∵ [tex]a_{5}=a_{4}-a_{3}+4[/tex]

∴ [tex]-2=2-a_{3}+4[/tex]

∴ [tex]-2=6-a_{3}[/tex]

∴ [tex]a_{3}=6+2=8[/tex]

* Similar use [tex]a_{4}[/tex] to find [tex]a_{2}[/tex]

∵ [tex]a_{4}=a_{3}-a_{2}+4[/tex]

∴ [tex]2=8-a_{2}+4[/tex]

∴ [tex]2=12-a_{2}[/tex]

∴ [tex]a_{2}=10[/tex]

* Finally use [tex]a_{3}[/tex] to find [tex]a_{1}[/tex]

∵ [tex]a_{3}=a_{2}-a_{1}+4[/tex]

∴ [tex]8=10-a_{1} +4[/tex]

∴ [tex]8=14-a_{1}[/tex]

∴ [tex]a_{1}=14-8=6[/tex]
