Answer:
1.50$
Step-by-step explanation:
difference in money amount: $6
difference in hours: 4
6 divided by 4 equals 1.50.
1.50 times 4 equals 6, hence its 1.50 per hour.
The rate of change in the Starbucks stock value is 150%.
Given that, At 10 AM, one share of Starbucks stock was $35. By 2 PM the price was $41.
We need to find the rate the Starbucks stock value was changing is - per hour.
What is the rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Now, the difference in money=41-35=$6
The number of hours between 10 AM to 2 PM is 4 hours.
The rate of change = The difference in money/Number of hours × 100
=6/4 × 100
=150%
Therefore, the rate of change in the Starbucks stock value is 150%.

Sherry is making snack mix for a school field trip.
The recipe shows the amount of each ingredient needed to make 6 bags.
Complete each statement to adjust the ingredients for each new situation if Sherry uses this recipe.
1. To make 18 bags of snack mix, Sherry needs____ cups of almonds
2. Sherry needs 6 cups of granola to make____ bags of the snack mix.
3. If Sherry uses 1 cup of cranberries, she will need to use____ cups of raisins.
4. The recipe will make____ bags of the snack mix if Sherry uses only 1 cup of granola.
Answer:
Step-by-step explanation:
1- To make 18 bags of snack mix, Sherry needs 4.5 cups of almonds.
As the original recipe is for 6 bags, and here Sherry wants to triple that amount. You have to multiply 1.5 x 3.
2- Sherry needs 6 cups of granola to make 12 bags of the snack mix.
If Sherry gets 6 bags using 3 cups of granola, she will get 12 by using 6 cups of granola.
3- If Sherry uses one cup of cranberries, she will need to use 2 cups of raisins.
As 1 cup of cranberries is the double of what the recipe states, Sherry should also double the amount of cups of raisins.
4- The recipe will make 2 bags of the snack mix if Sherry uses only one cup of granola.
As 1 cup of granola is a third of the amount detailed in the recipe for 6 bags, the amount of bags will also be reduced to a third. 6/3=2

Suponha que, em sua empresa familiar,
Dona Joana vende um salgadinho a x reais
(por unidade). A quantidade vendida por dia
diminui com o preço e é dada por 32 – x.
Portanto, a equação quadrática
x (32 – x) = 31
significa que, com o preço x, o total
apurado nas vendas, isto é, a receita, é igual
a 31 reais por dia.
Qual o menor preço X do salgadinho para
que isto ocorra?
Answer:
1 Real
Step-by-step explanation:
Para encontrarmos o menor preço "x", do salgadinho que a empresa familiar Dona Joana costuma vender, basta resolvermos a equação quadrática informada pelo enunciado. Veja:
x(32 − x) = 31
Com a equação de 2º grau na forma fatorada, é possível desmembrarmos em duas outras equações. Uma delas é x = 31, que veio dos termos em negrito: x(32 − x) = 31, e a outra raiz é: 32 - x = 31, que veio dos termos em negrito x(32 − x) = 31.
Calculando as raízes:
x = 31
ou
32 - x = 31 ⇔ -x = 31 - 32 ⇔ -x = -1 ⇔ x = 1
Assim, as raízes são x = 31 e x = 1.
Testando os valores:
Para x = 31:
x(32 − x) = 31
31(32 - 31) = 31
31(1) = 31
31 = 31
Para x = 1
x(32 − x) = 31
1(32 - 1) = 31
1(31) = 31
31 = 31
Ok, está correto! E o menor valor do salgadinho para que a receite dê R$ 31,00 é R$ 1,00.
Resposta:
Portanto, o menor preço que o salgadinho pode ter para que a receita seja igual 31 reais é R$ 1,00.

Answer:
108º
Step-by-step explanation:
to find the sum of interior angles: ( n − 2 ) × 180 = x
x = 540º
n = # of interior angles
first, solve for n
(n - 2) • 180 = 540 distribute to 180 to (n - 2)
180n - 360 = 540 add 360 to both sides
180n = 900 divide both sides by 180
n = 5
to find measure of each angle:
540 ÷ 5 = 108º

The length of the segment GH is given by the distance D = 7.3 units
What is the distance of a line between 2 points?The distance of a line between 2 points is always positive and given by the formula
Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )
The distance between A and B is D , and the distance D is
Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²
Given data ,
Let the first point be G ( -9 , -4 )
Let the second point be H ( -2 , -6 )
Let the length of the segment GH = D
Now , distance between G and H is D , and the distance D is
Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²
On simplifying , we get
D = √ ( -9 - ( - 2 ) )² + ( -4 - ( -6 ) )²
D = √ ( -7 )² + ( 2 )²
On further simplification , we get
D = √ ( 49 + 4 )
D = √53
D = 7.28 ≈ 7.3 units
Hence , the distance is 7.3 units

The following graphs are transformations of f(x) = x^2.
Complete the boxes below to describe the transformations.
A(x) = f (x + _) + _
B(x) = f (x + _) + _
C(x) = f (x + _) + _
D(x) = f (x + _) + _
Step-by-step explanation:
Let's look at A(x) and see how it is different from f(x)
it is shifted downwards by 8 unitsit is not shifted to the left or the rightTherefore A(x) = f(x) - 8
Let's look at B(x) and see how it is different from f(x)
it is not shifted downwards or upwardsit is shifted to the left 7 unitsTherefore B(x) = f(x + 7)
Let's look at C(x) and see how it is different from f(x)
it is shifted upwards by 4 unitsit is shifted to right by 5 unitsTherefore C(x) = f(x - 5) + 4
Let's look at D(x) and see how it is different from f(x)
it is not shifted downwards or upwardsit is not shifted to right by 12 unitsTherefore D(x) = f(x - 12)
PLEASE HELP ASAP!! Students take a test worth a total of 100 points. There are 24 questions on this test, some are worth 5 points and others are worth 3. Solve for how many 5 point questions and 3 point questions there are on the test
Answer:
There are 14 5-point questions and 10 3-point questions.
Step-by-step explanation:
Form 2 equations:
Let x= 5-point questions
Let y= 3-point questions
1.) x+y=24
2.) 5x+3y=100
Use substitution by reforming equation 1 in terms of x or y (I used y)
1.) y=24-x
Sooo, substitute this into the y in the 2nd equation:
5x+3(24-x)=100
5x+72-3x=100
2x=100-72
2x=28
x=14
Now that we have x, substitute this into the 1st equation to get y:
1.) y=24-x
y=24-14
y=10
In conclusion, there are 14 5-point questions and 10 3-point questions.
Answer:
There are 14 questions that are worth 5 points and there are 10 questions that are worth 3.
Step-by-step explanation:
14 x 5 = 70
10 x 3 = 30
70 + 30 = 100
14 + 10 = 24 questions total

Zx and Zy are supplementary angles. Zy measures 108°,
What is the measure of Zx?
Stuck? Watch a video or use a hint.
Answer:
72°
Step-by-step explanation:
Given
Zy = 108°
Zx = ?
We know
Zx + Zy = 180° {being supplementary angles }
Zx + 108° = 180°
Zx = 180° - 108°
Zx = 72°

No Triangles: A, C
One Triangle: D, F
Many Triangles: B, E
Step-by-step explanation:
¯\_(ツ)_/¯
The no triangle possible: B and D, one triangle possible : A, C, and E, and many triangles: F.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
Checking for the A)
4 + 8 > 10
There is one triangle possible.
For B)
60 + 40 + 90 = 190 ≠ 180 degree
No triangle possible because the sum of the angles in triangle is 180 degree.
For C)
There are two sides are given and one angle so SAS
One triangle is possible.
For D)
7 + 5 = 12
There is no triangle possible because the sum of the two sides is equal to the third side.
For E)
By the rule of ASA one triangle is possible.
For F)
60 + 80 + 40 = 180 degree
There are three angles are given, but no sides are given, so many triangles are possible.
Thus, the no triangle possible: B and D, one triangle possible : A, C, and E, and many triangles: F.
