Using the number 234.58937 what is the sum of the hundreds digit and the hundredths digit? A) 12 B) 11 C) 10 D) 9 E) 8

Answer:

12.5 per kilometers

Step-by-step explanation:

to find speed is going to be distance divided by time so 62.5/5

so her speed is going to be 12.5

Amanda's average speed while riding her bicycle is found by dividing the total distance of 62.5 kilometers by the total time of 5 hours, resulting in an average speed of 12.5 kilometers per hour.

To calculate her speed, we use the formula for speed, which is speed = distance ÷ time. Applying the given values, we have speed = 62.5 kilometers ÷ 5 hours.

Therefore, Amanda's average speed is 12.5 kilometers per hour. This calculation involves dividing the total distance traveled by the total time taken, resulting in the average speed over the journey.

Answer:

D

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x, y) → (- y, x)

A translation of 3 units up → + 3 in the y- direction, that is add 3 to the y- coordinate, hence

(x, y) → (- y, x) → (- y, x+ 3) → D

Answer:

Well, y = 2x - 3.

Step 1:

Subtract 2x from both sides.

-y = -2x + 3.

Step 2:

Divide it all by negative 1.

y = 2x - 3.

IF YOU WANT TO SOLVE FOR X:

Well, x = .5y + 3/2

Which equals to:

(y + 3)/2.

Step 1:

Add y to both sides.

2x = y + 3.

Step 2:

Divide it all by 2:

x = .5y + 3/2

Which equals to:

(y + 3)/2.

They are the same.

Answer:

173.15 ft.  

Step-by-step explanation:

Please find the attachment.

Let L be the length of kite.  

We have been given that a kite is stuck in  36-ft tree. The angle of elevation from the kite and the ground is 12.

We can see from our attachment that kite and tree form a right triangle. height of tree is opposite of angle of elevation and length of kite is hypotenuse.

Since we know that Sine relates the opposite and hypotenuse of a right triangle, so we will use sine to find the length of kite.

[tex]sin(12)=\frac{36}{L}[/tex]    

[tex]L=\frac{36}{sin(12)}[/tex]

[tex]L=\frac{36}{0.207911690818}[/tex]  

[tex]L=173.1504364105882792\approx 173.15[/tex]

Therefore, the length of kite is 173.15 ft.

Answer:

F  $185

G 12 weeks

Step-by-step explanation:

Assuming your equation is correct

y = -35x +500

We want to let x=9

y = -35(9) +500

y = -315+500

y =185

Jason will have $185  after 9 weeks

If he has 80 dollars left we put that in for y and solve for x

80 = -35x +500

Subtract 500 from each side

80-500 = -35x +500-500

-420 = -35x

Divide each side by -35

-420/-35 = -35x/-35

12 = x

After 12 weeks he will have 80 dollars left

Answer:

Bernie, Chrissy, Dina and Frank

Step-by-step explanation:

if all 73 tickers are sold, the theatre makes $438 so each ticket is worth $438/73

this equals to $6.00 for one ticket

this means that Bernie, Chrissy, Dina and Frank have enough money to see the movie

Answer:

Bernie, Chrissy, Dina, and Frank are able to go.

Step-by-step explanation:

The question is not entirely clear. I take it that 73 tickets will bring in 438 dollars. If that is so, each ticket is selling for the solution of this proportion.

x / 1 = 438/73       Just do the division on the right

x = 6.00 dollars.

So Amanda will not be able to go.

Even will not be able to go.

Answer:

x=12 makes (X-12)/(x-8) equal to zero

x=8 makes (X-12)/(x-8)  undefined

Step-by-step explanation:

(x-12)/(x-8) = 0

The  first step is to multiply each side by x-8

 (x-8) *(x-12)/(x-8) = 0 * (x-8)

This cancels the denominator.  x≠ 8 because the denominator would equal 0 and then it becomes undefined.

x-12 = 0

Add 12 to each side

x-12+12 = 0+12

x = 12

The statement 'the length of a rectangle if the length is twice the size of the width increased by one' translates into the equation l = 2w + 1 in mathematical terms. This equation represents a relationship between the rectangle's length (l) and width (w), with the length being twice the width, increased by one.

The correct translation of the statement 'the length of a rectangle if the length is twice the size of the width increased by one' is mathematical in nature. This sentence is describing a relationship between the length and width of a rectangle.

To put it into an equation, start by denoting the width of the rectangle as 'w'. The statement says that the length is twice this width (2w) plus one. So, the length 'l' can be represented as:

l = 2w + 1

This equation shows the relationship between the length and width of a rectangle according to given statement. For practical purposes, you can insert a numerical value for width 'w' and perform the calculation on the right side to find the length 'l'.

The inverse of the function x + 2y + 3 = 0 is found by first expressing the function explicitly as y = -½x - 1½ and then swapping x and y to solve for the new y, yielding the inverse function y = -2x - 3.

To find the inverse of a function, we typically swap the roles of x and y, and then solve for y. Given the function x + 2y + 3 = 0, we first write the function explicitly as y in terms of x:

y = -½x - ³2

Now let's find the inverse:

Answer:

$13.66

Step-by-step explanation:

Multiply the amount of Dijon mustard and mustard by its price, then add them together.

3 * 3.69 = 11.07

.5 * 5.18 = 2.59

Add these sums together.

11.07 + 2.59 = 13.66

Answer:

Fried crab cakes = $4.50

Cup of gumbo = $3.25

Step-by-step explanation:

Let's make the price of fried crab cakes = x and the price of a cup of gumbo = y. Set up two equations for x and y and solve for each variable.

4 people ordered x and 4 people ordered y for a total of 31 dollars, so this equation would look like: 4x + 4y = 31

2 people ordered x and 1 person ordered y for a total of $12.25, so this equation would look like: 2x + y = 12.25

Now you have your two equations-- solve for a variable in one of the equations and substitute that value into the other equation.

The easiest way to start would be to solve for y in the second equation by subtracting 2x from both sides.

y = 12.25 - 2x

Substitute this value into the first equation.

4x + 4(12.25 - 2x) = 31

Now solve for x-- start by distributing 4 inside the parentheses.

4x + (49 - 8x) = 31

Combine like terms.

-4x + 49 = 31

Subtract 49 from both sides.

-4x = -18

Divide both sides by -4.

x = 4.5

Substitute this value of x into our starting equation for which we solved for y.

2(4.5) + y = 12.25

Multiply 2 and 4.5 together.

9 + y = 12.25

Subtract 9 from both sides.

y = 3.25

Each order of fried crab cakes is worth the x-value [$4.50] and each cup of gumbo is worth the y-value [$3.25].

In this system of linear equations, by denoting the cost of the fried crab cakes as x dollars, and the cost of a cup of gumbo as y dollars, we find that each order of fried crab cakes is $4.50 and each cup of gumbo is $3.25.

The subject of this problem is linear algebra, and it can be solved using a system of linear equations. Let's denote the cost of the fried crab cakes as x dollars, and the cost of a cup of gumbo as y dollars.

From the information given in the problem, we can create the following two equations:

Now, we can solve this system of equations. Divide the first equation by 2, which will give us:

2x + 2y = 15.5

Then subtract the second equation from the result, which will give us:

y = 3.25

Substitute y = 3.25 into the second equation:

2x + 3.25 = 12.25

Finally, solve for x:

x = 4.5

So, each order of fried crab cakes is $4.50 and each cup of gumbo is $3.25.

Answer:

5 Hours

Step-by-step explanation:

Given :- 2 hours can be earned each day if she eats all of her vegetables and does all of her chores.

Saved hours at the start of the week = 3 hours

Hours earned in 4 days = 2 hours × 4

                                       = 8 hours

Hours used in 4 days = 6 hours

Hours left after 4 days = Saved hours at the start of the week + Hours earned in 4 days - Hours used in 4 days

Hours left after 4 days = 3 + 8 - 6

                                       = 5 hours
