Answer:
Let's define the variables:
x = number of hot dogs he buys
y = number of cheeseburgers he buys.
Each hot dog costs $2, then the price of x hotdogs is:
x*$2
Each cheeseburger costs $3, then the price of y cheeseburgers is:
y*$3
The total price is:
x*$2 + y*$3
And we want to find an equation to see how much he can buy for exactly $10, then we have:
x*$2 + y*$3 = $10
Or, if he can use $10 or less than $10, the inequality would be:
$0 ≤ x*$2 + y*$3 ≤ $10
Determine if the two triangles shown are similar. If so, write the similarity statement.
Question 18 options:
A)
Impossible to determine.
B)
ΔGCB ∼ ΔGFE
C)
The triangles are not similar.
D)
ΔBCG ∼ ΔEFG
Answer:
C. The triangles are not similar
Step-by-step explanation:
For two triangles to be considered similar, the 3 angles of one triangle must be equal or congruent to the corresponding 3 angles of the others.
The only angle in ∆BCG that is equal to the corresponding angles in ∆EFG is <BGC. The remaining 2 angles in ∆BCG are not congruent to the corresponding 2 angles in ∆EFG.
Therefore, we can conclude that both triangles are not similar.

How many miles would you have to move so that each moving company would charge you the same total amount
Answer: 10 miles
Step-by-step explanation:
Given that :
Company A:
Flat rate = $30
Charge per mile = $1
Company B:
Flat rate = $20
Charge per mile = $2
Let x = number of miles
Company A total :
30 + x
Company B total :
20 + 2x
Miles needed To get the same total :
30 + x = 20 + 2x
30 - 20 = 2x - x
10 = x
Hence, 10 miles will be moved

Which expressions are equivalent to 6a(5+d) ?
SELECT EACH CORRECT ANSWER (theres more than 1)
30a+6ad
(6a⋅5)+(6a⋅d)
11a + d
30a+(6a⋅d)
30ad
Answer:
first, second and fourth
Step-by-step explanation:
If you use distribution,
6a(5+d) is the same as
6a(5) + 6a(d)
Multiplied = 30a + 6ad
So it's the 1st 2nd and fourth choice.
1st is stated above when multiplied out and combined.
2nd is after distribution.
4th choice is basically combination of 1 and 2 where one is combined (first term) and the second one just set up to be multiplied.
It cannot be third because you are multiplying the factors and not adding so you cannot have 11a.
It cannot be last choice because you have different types of terms that cannot be combined (one with a alone and one with ad)
Answer:
(6a*5) + (6a*d)
30a + 6ad
30a + (6a*d)

Steve worked 7 hours Monday, 5 ¾ hours on Tuesday and 3.2 hours on Friday. If Steve earns $8.50 per hour, how much money did he earn for these three days?
Answer:
135.58 just did this
Step-by-step explanation:
First, I calculated the amount of money he got on Monday. I multiplied. 8.50 x 7 which equals 59.50. Then, I calculated the amount of money he got on Tuesday. I multiplied 8.50 (since that is the number of money he gets paid) to 3.2 (since that’s the amount of hours he works). I got 27.200. Then lastly, I calculated the amount of money he got on Friday. So first I changed 5 3/4 into a decimal. This is 5.75. After, I multiplied 8.50 x 5.75, and got 48.8750.lastly, I added and got 135.575. So if you round it, it will be 135.58

Find the area of square that has the same perimeter as a rectangle whose length and breadth are 18cm and 8cm respectively
Answer:
169
Step-by-step explanation:
The perimeter of the square and rectangle are said to be the same. Therefore we have to find the perimeter which is :Perimeter of a rectangle= 2(length+breath)
2(18 + 8)
2(26)
52.
A square has four equal sides.
The length will be determined by dividing 52 by 4
[tex]52 \div 4 = 13[/tex]
The length is 13.
Since the area of a square is
[tex] {l}^{2} = {13}^{2} [/tex]
L is length.
The answer is
[tex] {169}^{2} [/tex]

You are using an exponential smoothing model for forecasting. The running sum of the forecast error statistics (RSFE) is calculated each time a forecast is generated. You find the last RSFE to be 34. Originally, the forecasting model used was selected because of its relatively low MAD of 0.4. To determine when it is time to re-evaluate the usefulness of the exponential smoothing model, you compute tracking signals. Which of the following is the resulting tracking signal?A) 85B) 60C) 13.6D) 12.9E) 8
Answer:
A)85
Step-by-step explanation:
Calculation for the resulting tracking signal
Using this formula
Tracking signal= Last forecast error statistics (RSFE) /Low MAD (Mean Absolute Deviation)
Let plug in the formula
Tracking signal=34/0.4
Tracking signal=85
Therefore the resulting tracking signal will be 85

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the total amount raised be y,
Amount raised per x mile is 60x,
And initial raise = 60
Total raise = y = 60 + 60x
Thus, the total amount raised by Rick in the walk-a-thon is shown by the expression y = 60 + 60x.

b) In the given figure, show that triangle PQR is a right angled triangle.
Answer:
Given that triangle RSP is a right triangle, then using the Pythagorean Theorem, RP = 5. (3²+4²=5²)
Plugging the 5 in to triangle RPQ, we find that the Theorem still works for that one, which means it is a right triangle (5²+12²=13²)
Step-by-step explanation:
Given that triangle RSP is a right triangle, then using the Pythagorean Theorem, RP = 5. (3²+4²=5²)
Plugging the 5 in to triangle RPQ, we find that the Theorem still works for that one, which means it is a right triangle (5²+12²=13²)
Answer:
see explanation
Step-by-step explanation:
Using Pythagoras' identity in Δ PRS
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, then
PR² = 3² + 4² = 9 + 16 = 25 ( take the square root of both sides )
PR = [tex]\sqrt{25}[/tex] = 5
Using the converse of Pythagoras in Δ PQR
If the longest side squared is equal to the sum of the squares on the other 2 sides then the triangle is right.
QR² = 13² = 169
PR² + PQ² = 5² + 12² = 25 + 144 = 169
Thus Δ PQR is a right triangle, with right angle at P

Answer:
Option A: 17,18,19 is the right answer.
Step-by-step explanation:
Let x be the first integer then the next two consecutive integers will be x+1, x+2
According to the given statement, the equation will be:
[tex]x + (x+1) + (x+2) = 54[/tex]
The equation is a linear equation in one variable, we have to solve the equation to get the values of integers
[tex]x+x+1+x+2 = 54\\3x+3 = 54\\3x = 54-3\\3x = 51\\\frac{3x}{3} = \frac{51}{3}\\x = 17[/tex]
Second integer = x+1 = 17+1 = 18
Third integer = x+2 = 17+2 = 19
The three integers are: 17,18 and 19

algebra 2 inverse functions
Answer:
The inverse function is:
{(1,8), (2,-1), (5,10), (-3,-3)}
Step-by-step explanation:
When a function is represented in the form of ordered pairs, the first element of each ordered pair is the input and the second element in each ordered pair is the output. In the inverse of a function the input becomes output and the output becomes input.
Given function is:
{(8,1), (-1,2), (10,5), (-3,-3)}
Reversing the order of elements of ordered pairs will given us the inverse function.
The inverse function is:
{(1,8), (2,-1), (5,10), (-3,-3)}
