Explanation:

Simply pair each value given in the sequence with a0,a1,a2,etc like so

a0 = 4

a1 = 11

a2 = 18

a3 = 25

a4 = 32

a5 = 39

If you are given the slope and y-intercept of a line, you can conclude several things about the line and use them to write the equation of the line in slope-intercept form, which is \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept.

For the values you've given:

- The slope (m) is 35.
- The y-intercept (b) is 550.

From these pieces of information, you can conclude:

1. **Slope (Steepness and Direction):** Since the slope is 35, this tells us that the line is relatively steep and rises quickly. The slope is positive, which means the line slants upwards from left to right. Specifically, for every one unit that x increases, y increases by 35 units.

2. **Y-intercept (Starting Point):** The y-intercept is where the line crosses the y-axis. Since the y-intercept is 550, it indicates that the line will cross the y-axis at the point (0, 550). This is the starting point of the line if you begin plotting from the y-axis.

With these conclusions, you can write the equation of the line in slope-intercept form:

\[ y = 35x + 550 \]

This equation allows you to predict or calculate the value of y for any given value of x along the line. It also enables you to graph the line by plotting the y-intercept and using the slope to determine the direction and steepness of the line. Remember, a line extends infinitely in both directions on the graph, so the portion you draw depends on the context or constraints of the particular situation you are modeling with the line.

Answer:

Area of ΔDEF is [tex]45\ cm^2[/tex].

Step-by-step explanation:

Given;

ΔABC and  ΔDEF is similar and ∠B ≅ ∠E.

Length of AB = [tex]2\ cm[/tex] and

Length of DE = [tex]6\ cm[/tex]

Area of ΔABC = [tex]5\ cm^2[/tex]

Solution,

Since, ΔABC and  ΔDEF is similar and ∠B ≅ ∠E.

Therefore,

[tex]\frac{Area\ of\ triangle\ 1}{Area\ of\ triangle\ 2} =\frac{AB^2}{DE^2}[/tex]

Where triangle 1 and triangle 2 is  ΔABC and  ΔDEF respectively.

If two triangles are similar, then the ratio of the area of both triangles is proportional to the square of the ratio of their corresponding sides.

[tex]\frac{5}{Area\ of\ triangle\ 2} =\frac{2^2}{6^2}\\ \frac{5}{Area\ of\ triangle\ 2}=\frac{4}{36}\\ Area\ of\ triangle\ 2=\frac{5\times36}{4} =5\times9=45\ cm^2[/tex]

Thus the area of  ΔDEF is [tex]45\ cm^2[/tex].

Answer:

There can be 180 apples in that box.

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Number of apples in a box < 200

2. It is known that 2, 3, 4, 5, or 6 kids can share these apples evenly. How many apples can be in that box?

The answer is that the number of apples that can be in the box is the highest multiple of 2, 3, 4, 5, and 6 that is close to 200.

The common multiples for this set of numbers are 60, 120, 180, 240, 300 and so on with 60 as the constant.

Therefore, the highest number that is multiple for this set of numbers and at the same time lower than 200 is 180.

There can be 180 apples in that box.

Answer:

Step-by-step explanation:

50% of 60? 0.5*60=30

10% of 60? 0.1*60=6

75% of 60? 0.75*60=45

50percent of 60 minutes is 30 minutes, 10percent of 60 minutes is 6 minutes, and 75percent of 60 minutes is 45 minutes.

50percent of 60 minutes: 50percent of 60 minutes is half of 60, which equals 30 minutes.

10percent of 60 minutes: 10percent of 60 minutes is 6 minutes (10percent of 60 is 6).

75percent of 60 minutes: 75percent of 60 minutes is 45 minutes (75percent of 60 is 0.75 * 60 = 45).

Answer:

40 and 50

Step-by-step explanation:

We know that River's mom drove for 45 minutes. Furthermore, at x miles per hour for a time amount y, she drove 10 miles, and at x+10 miles per hour for time amount z, she drove 25 miles. We can set up the equations like this:

x*y = 10

(x+10)*z = 25

y+z = 0.75

I knew to include time as the variable because time was given at the end, and is the only way possible to solve this. Furthermore, we can multiply x and y because we drive for x miles per hour for y hours, so

[tex]\frac{x miles}{hours}  * \frac{yhours}{1}  = xmiles*y[/tex]

I turned 45 into 0.75 as 45 is 3/4 of an hour, and y and z are in hours.

We're kind of stuck here, so it would be nice if we could limit the variables in an equation. One way to do this would be to solve for y in the first equation, so x=10/y. Then, we can plug that into the second equation to get

(10/y+10)*z=25

Combining that with the third equation, we can solve for z in the second equation to get that 25/(10/y+10)=z, and then plug that into the third to get that

y+25/(10/y+10) = 0.75

Multiplying both sides by 10/y+10 to get rid of the denominator, we get

10+10y+25=7.5/y+7.5

Then we multiply by y to get rid of the denominator

10y+10y²+25y=7.5+7.5y

Subtracting 7.5+7.5y to get everything on one side for a quadratic equation

10y²+27.5y-7.5=0

Plugging this into the quadratic equation, we get than y either equals -3 or 0.25. It's clear that you can't have negative time, so y = 0.25

Then, 0.75-0.25=0.5=z, and 10/0.25=40, so x=40, and x+10=50 for the 2 driving speeds

There were 980 student desks originally before the purchase was made.

Step-by-step explanation:

Total desks purchased = 295

As 50 new desks are for teachers, therefore, we will subtract this amount from total;

Desks purchased for students = 295-50 = 245

Let,

x be the number of original student desks, therefore,

[tex]\frac{1}{4}\ of\ x=245\\\frac{x}{4}=245[/tex]

Multiplying both sides by 4

[tex]4*\frac{x}{4}=245*4\\x=980[/tex]

There were 980 student desks originally before the purchase was made.

Answer:

From what I can tell from the image, b is equivalent to B.) 50°

Step-by-step explanation:

So to start off 2a=80° there is 2 a's. so  you subtract 80° from 180° to get 100°.

now b=c and their is 100° left over. So 100°/2 is 50° because if b=50° and c=50° both angles equal 100°.

Answer : The correct option is, (B) 50

Step-by-step explanation:

As we are given :

2a = 80

b = c

As we know that:

The sum of interior angles of a triangle is equal to [tex]180^o[/tex].

That means,

[tex]\angle A+\angle B+\angle C=180^o[/tex]

[tex]80^o+\angle B+\angle C=180^o[/tex]

and, [tex]\angle B=\angle C[/tex]

So,

[tex]80^o+2\angle B=180^o[/tex]

[tex]2\angle B=180^o-80^o[/tex]

[tex]2\angle B=100^o[/tex]

[tex]\angle B=\frac{100^o}{2}[/tex]

[tex]\angle B=50^o[/tex]

Thus, the value of 'b' is [tex]50[/tex]

Answer:

a) c = 65.532 cm

P = 145.532 cm

b) A = 751.754 cm²

Step-by-step explanation:

This is an isosceles triangle.  The given angle is obtuse, so it must be the vertex angle.

a) One way to find the length of the third side is law of cosine:

c² = a² + b² − 2ab cos C

c² = 40² + 40² − 2(40)(40) cos 110°

c = 65.532

Another way is to cut the triangle in half and use sine.

sin (110°/2) = (c/2) / 40

c = 80 sin 55°

c = 65.532

The perimeter is the sum of the sides:

P = 40 + 40 + 65.532

P = 145.532

b) You can find the area using the SAS equation:

A = ½ ab sin C

A = ½ (40)(40) sin 110°

A = 800 sin 110°

A = 751.754

Another way is to split the triangle in half, find the height using cosine, then use half the base times height.

cos (110°/2) = h / 40

h = 40 cos 55°

h = 22.943

A = ½ ch

A = ½ (65.532) (22.943)

A = 751.754

Step-by-step explanation:

The given function is

[tex]f(x)=-\frac{2}{9}x +\frac{1}{3}[/tex]

This given function is a linear function, because its variables have one as exponent, we can also say that its variables are linear.

This function, as a linear one, it's represented as a line.

Additionally, the form of this function is called slope-intercept form as

[tex]f(x)=mx+b[/tex]

Where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept.

Answer:

20 cups of broth are needed to make 30 servings of the soup.

Step-by-step explanation:

This is a typical proportion math problem.

Just set up the proportion and solve for the unknown variable, let it be x, because it's simple to use.

12/8=30/x

simplify 12/8 to 3/2,

3/2=30/x

cross product,

2*30=3*x

60=3x

x=60/3

x=20

Number of cups of broth needed for making 30 servings is 20.

Proportions are defined as the concept where two or more ratios are set to be equal to each other.

Suppose we have two ratio p : q and r : s.

If both these ratios are proportional, then we can write it as p: q : : r : s.

This is same as p : q = r : s or p/q = r/s

We have,

Cups of broth needed for 12 servings of soup = 8 cups

Let cups of broth needed for 30 servings of soup = x cups

Using the concept of proportion,

12 / 8 = 30 / x

Doing the cross multiplication,

12x = 8 × 30

12x = 240

x = 240 / 12

x = 20

Hence 20 cups of broth are needed to make 30 servings of the soup.

[tex](-15)^{-1}[/tex] must be divided by 1 in order to have the quotient as [tex](-15)^{-1}[/tex]

Step-by-step explanation:

Given:

Dividend = [tex](-15)^{-1}[/tex]

Quotient =  [tex](-15)^{-1}[/tex]

We notice that the dividend and the quotient are equal. This means the divisor is 1.

By identity property of 1, any number divided by 1 is equal to the same number or the quotient of a number divided by 1 is equal to the number itself.

So, we can write this as:

[tex]\frac{(-15)^{-1}}{1}=(-15)^{-1}[/tex]

The rate of change in the above equation is 3 dollars per game and it interpret the cost per game.

The initial value in the above equation is 8 dollars, which interpret the entry fee that every one person has to pay to enter the fair.

Step-by-step explanation:

Let the admission cost of the fair is $x and each game is $3.

Now, Steven went to the state fair, played  4 games and spent a total of $20 on  admission and games.

So, we can write 20 = x + 4 × 3 {As the relation is linear}

⇒ x = $8

Therefore, the admission cost in the fair is $8.

Therefore, the equation that models the situation is  

C = 8 + 3x ............ (1)

Where C is the total cost and x is the number of games played.

So, the rate of change in equation (1) is 3 dollars per game and it interprets the cost per game.

Again, the initial value in equation (1) is 8 dollars, which interprets the entry fee that each person has to pay to enter the fair. (Answer)

Final answer:

The simplified expression for 3.4m + 2.4m is 5.8m. You simply add the coefficients of like terms.

Explanation:

To simplify the expression 3.4m + 2.4m, we need to combine like terms. The term 'like terms' refers to terms that have the exact same variable raised to the same power. In this case, both terms have 'm' as the variable, and it's not raised to any power (which is the same as being raised to the power of 1).

Combine the coefficients (numerical parts) of the like terms:

3.4m + 2.4m = (3.4 + 2.4)m

Add the coefficients: 3.4 + 2.4 = 5.8

Therefore, 3.4m + 2.4m = 5.8m.
