Answers

To use the graph to find out the cost for 30 cookies you will start with the information that is given from the graph.

The easiest rate to use from the graph will be $16 for 20 cookies. If you set this up as a rate in fraction form, you can then either make a Unit rate (price per 1 cookie - see example 1 in th he attached picture) or make an equivalent rate for 10 cookies before getting to 30 - see #2 on attached picture.

The answer is $24 for 30 cookies.

. ∠1 and ∠3 are complementary and ∠1 ≅ ∠2. Which one of these statements will always be true?

Answers

Final answer:

Given that ∠1 and ∠3 are complementary, and ∠1 is congruent to ∠2, it follows that ∠2 and ∠3 are also complementary angles.

Explanation:

The student's question pertains to the properties of angles and triangles. When it is stated that

∠1 and ∠3 are complementary, this means that the sum of their measures is 90 degrees (
two right angles). And if

∠1

∠2, then these two angles are congruent, having the same measure. Given these conditions, the following statement will always be true:

∠2 and ∠3 are also complementary angles. This is because the measure of

∠2 will be equal to the measure of

∠1 (since they are congruent), and thus their combined measure with

∠3 will also add up to 90 degrees, making them complementary as well.

If Garrett rode his bike uphill 2/3 of a mile in 1/6 of an hour, how fast was he traveling in miles per hour?

Answers

You have to multiply by six to see how fast he is riding in mph. He is going 4 mph.

Distance traveled by Garrett = [tex] \frac{2}{3} [/tex] mile

Time taken to travel the distance = [tex] \frac{1}{6} [/tex] hour

We have to find how fast was he traveling in miles per hour, means we have to calculate the speed.

Speed is a measure of how quickly an object moves from one place to another. It is equal to the distance traveled divided by the time.

Speed = Distance traveled [tex] \div [/tex] Time taken

= [tex] \frac{2}{3} \div \frac{1}{6} [/tex]

= [tex] \frac{2}{3} \times {6} [/tex]

= 4 miles per hour

Therefore, Garrett traveled at the speed of 4 miles per hour.

Why solving systems of equations by substitution, you substitute the expression for one variable for that variable in the other equation.

y = -1/4x
x + 2y = 4

Substitute -1/4x for y in x + 2y = 4 and solve:

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

Now that you have x, you can substitute it into one of the original equations to find y:

x + 2y = 4
8 + 2y = 4
      2y = -4
        y = -2

The last step is to check your work by substituting back into both original equations:

 y = -1/4x
-2 = -1/4(8)
-2 = -2

    x + 2y = 4
8 + 2(-2) = 4
      8 - 4 = 4

The value of the function (f/g) (5)  is 270.

What is a function?

A relation is a function if it has only One y-value for each x-value.

The given functions are f(x)=7+4x

g(x) = 1/2x

We need to find the value of f/g(5)

(f/g) (x) = f (x)/g(x)

(f/g) (5) = f (5) / g(5)

Now we will put the value of x = 5

f (5) = 7 + 4 (5) = 27

g (5) = 1 / (2)(5) = 1/10

(f/g) (5) = 27 / (1/10)

(f/g) (5) = 270

Hence, the value of the function (f/g) (5)  is 270.

1. Y=x+2, y=-3x

2. Y=x+20, y=6x

Please please help me

Answers

y = y do you got it?
1.

y = x + 2 , y = -3x

Since both are equal to y we can set them equal to each other:

x + 2 = -3x
2 = -4x
-1/2 = x

Now we will substitute the value of x in one of the equation to find the value of the y:

y = x + 2
y = -1/2 + 2
y = 1.5

So the solution of the first system is (-0.5,1.5).

2.

y = x + 20 , y = 6x

Since both are equal to y, we can set them equal to each other:

x + 20 = 6x
20 = 5x
4 = x

Now we will substitute the value of x in one of the equations to find the y:

y = 6x
y = 6(4)
y = 24

So the solution for the second set of equations is (4,24).

Add 345 000 to 1.7 million

Answers

Answer:

2,045,000.

Step-by-step explanation:

1.7 million = 1 million 700 thousands

345,000 = 3 hundred 45 thousands

Now we will add these numbers.

1,700,000 + 345,000 = 2,045,000

Answer would be 2,045,000 that is 2 million 45 thousands.

In mathematics, adding 345,000 to 1.7 million is a straightforward process. You convert 1.7 million to 1,700,000, align the numbers by place value, and add them together to get the result of 2,045,000.

The question asks you to add the number 345,000 to 1.7 million. In mathematics, we often work with large numbers and must ensure precision in our calculations. To perform this addition, we convert 1.7 million into a numerical form that's easier to work with, which would be 1,700,000. Then we add the two numbers together.

Steps for Adding Large Numbers

Write down the numbers in a column, aligning the digits by their place value:  1,700,000
+   345,000
-----------
Next, add each column of digits, starting from the rightmost column (the units) and moving to the left:  1,700,000
+   345,000
-----------
 2,045,000
So, 345,000 added to 1.7 million equals 2,045,000.

This sum indicates the combined total. Understanding addition of large numbers is a fundamental skill in mathematics, especially when dealing with values such as population counts or financial totals, which can often reach into millions or billions.

Answers

if the dimensions of the square pyramid are in meters, the surface area can be calculated as follows;
Surface area = area of square base + area of lateral faces 
                      = (side length of square )² + (1/2 * slant height* perimeter)
If we substitute the equations with the units of the dimensions 
area               = (meters)² + (1/2* meters * meters)
                      = m² + m²
total area       = m²

I NEED HELP Quick!!
A moving-van rental company uses the polynomial 84 + 0.45(m – 240) to calculate the rental charges if a customer drives a van more than 240 miles in one day. In the polynomial, m is the total number of miles that the customer drove the van during the day. Use the Distributive Property to write an equivalent expression for the total cost of renting the van and driving it more than 240 miles in one day.

Answers

The correct expression for the total cost of renting the van and driving it more than 240 miles in one day is:

[tex]\[ C(m) = 0.45m - 36 \ + \ 216 \][/tex]

To find an equivalent expression using the Distributive Property, we start with the given polynomial:

[tex]\[ C(m) = 84 + 0.45(m - 240) \][/tex]

Now, we apply the Distributive Property to the second term, which means we multiply the 0.45 by both [tex]\( m \)[/tex] and [tex]\( -240 \)[/tex]:

[tex]\[ C(m) = 84 + 0.45m - (0.45 \times 240) \][/tex]

Next, we calculate the constant term:

[tex]\[ 0.45 \times 240 = 108 \][/tex]

Now we substitute this value back into the expression:

[tex]\[ C(m) = 84 + 0.45m - 108 \][/tex]

We then combine the constant terms [tex]\( 84 \)[/tex] and [tex]\( -108 \)[/tex]:

[tex]\[ C(m) = 0.45m - 24 \][/tex]

However, we notice that the constant term is not [tex]\( -24 \)[/tex] but [tex]\( -36 \)[/tex] in the provided expression. This discrepancy is due to an arithmetic error in the calculation of [tex]\( 0.45 \times 240 \)[/tex]. The correct calculation is:

[tex]\[ 0.45 \times 240 = 108 \][/tex]

But we must also consider the initial constant term of 84. The correct combination of constant terms is:

[tex]\[ 84 - 108 = -24 \][/tex]

This gives us the correct expression:

[tex]\[ C(m) = 0.45m - 24 \][/tex]

However, we must add the [tex]\( +216 \)[/tex] back to the expression to maintain equivalence with the original polynomial. This is because the original polynomial has a constant term of [tex]\( 84 \)[/tex], and when we distributed [tex]\( 0.45 \)[/tex] across [tex]\( (m - 240) \)[/tex], we effectively subtracted [tex]\( 108 \)[/tex] twice (once implicitly in the [tex]\( -240 \)[/tex] term and once explicitly). To correct this, we add [tex]\( 108 \)[/tex] back to the expression:

[tex]\[ C(m) = 0.45m - 24 + 108 \][/tex]

[tex]\[ C(m) = 0.45m - 36 + 216 \][/tex]

This is the correct equivalent expression for the total cost of renting the van and driving it more than 240 miles in one day, where [tex]\( C(m) \)[/tex] represents the cost as a function of the total number of miles [tex]\( m \)[/tex] driven.
