A 2oz cup of frozen yogurt has 50 calories in it. How many calories are 7 oz?
Which of these situations is not a situation of proportionality? Immersive reader A person's age and height The cost of filling up with gasoline and the number of liters purchased The number of working days and the salary The number of movie tickets purchased and the total bill
Answer:
A person's age and height
Step-by-step explanation:
Required
Select which do not represent proportionality
Proportionality exists when a unit rate can be calculated.
For instance:
- If 2 litres of gas is $2, then the unit rate is $1 per litre
- If an employee is paid $100 for 5 days, then the unit rate is $20 daily
- If 5 movie tickets cost $50, then the unit rate is $10 per movie
The above scenario are used to describe options (2 - 4) because they can be expressed in unit rates.
However, this is not the same for age and height because age is not a function of height and height is not a function of age. In other words, they can not be expressed in proportions.
So, option (a) is not a situation of proportionality.

Use the graph of function g to answer the following questions
What is the value of g(1)
The value of g(1) is 2 because the graph represents the greatest integer function, the answer is 2.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
The graph of the greatest integer function is shown in the picture:
From the graph:
g(1) = 2
g(2) = 4
g(3) = 4
g(4) = 4
g(5) = 4
And so on
Thus, the value of g(1) is 2 because the graph represents the greatest integer function, the answer is 2.

Identify the correct phrase to complete the statement.
A central angle has a measure of 1 radian if:
A. the length of the arc it intercepts is twice the length of the radius.
B. the central angle is 90°.
C. the length of the arc it intercepts is the same as the length of the
radius.
O D. the radius has a length of 1
Answer:
C.) the length of the arc it intercepts is the same as the length of the radius
Step-by-step explanation:
The length of the arc it intercepts is the same as the length of the
radius option (C) is correct.
What is a circle?It is defined as the combination of points that, and every point has an equal distance from a fixed point (called the center of a circle).
As we know, the relationship between arc length and the central angle:
s = rθ
[tex]\rm \theta = \dfrac{s}{r}[/tex]
Where 's' is the arc length and θ is the central angle, r is the radius of the circle.
If θ = 1 radian
Then,
s = r
Thus, the length of the arc it intercepts is the same as the length of the
radius option (C) is correct.

Answer:
C. y + 7 = -7(x - 3)Step-by-step explanation:
The equation of a line is:
y - y₀ = m(x - x₀)
where m is the slope and (x₀, y₀) is the point which the line passes through
The product of slopes of two perpendicular lines is -1
so if given lines slope is ¹/₇ them:
¹/₇·m = -1
m = -7
(3, -7) ⇒ x₀ = 3, y₀ = -7
Therefore:
y - (-7) = -7(x - 3)
y + 7 = -7(x - 3)

P. Antonio is ordering 5 identical sandwiches and a bag of chips. The bag of chips costs $1.25, and the entire order costs $38.75. What is the price of one sandwich
Answer:
$7.50
Step-by-step explanation:
Let the price of one sandwich = x
Hence,
The total cost = Cost of 5 identical sandwiches + 1 bag of chips
The bag of chips costs $1.25, and the entire order costs $38.75.
Hence:
$38.75 = 5x + $1.25
5x = $38.75 - $1.25
5x = $37.50
x = $37.50/5
x = $7.50
Therefore, the price of one sandwich is $7.50
Write y – 3 = 23 (x – 2) in standard form. PLEASE HELP BEST ANSWER AND EXPLANATION WILL GET BRAINLIEST!!
Answer:
23x -y = 43
Step-by-step explanation:
in slope intercept form, we have y=mx+b where m=slope, b= y intercept
first let's simplify the expression 23(x-2)
y-3 = 23x - 23*2
y-3 = 23x - 46
now add 3 to both sides to move numbers to the right hand side
y -3 +3 = 23x -46 +3
y = 23x - 43
convert to standard form by having x and y on one side, numbers on the other.
add 43 to both sides
y+43 = 23x
subtract y from both sides
43 = 23x - y

x^3+bx^2-4x-20=0
find b
find the roots
Answer:p(x) = x^3 - 5x^2 - 4x + 20
Step-by-step explanation:
1, - 1, 2, - 2, 4, - 4, 5, - 5, 10, - 10, 20, - 20
P(2) = 2^3 - 5 × 2^2 - 4 × 2 + 20
= 8 - 20 - 8 + 20 = 0,
so, 2 is one of its roots (zeros)
So,
x - 2 is one of the factors of p(x)
So, on dividing p(x) by x - 2 we get
P(x) = (x - 2) (x^2 - 3x - 10)
= (x - 2) (x^2 - 5x + 2x - 10)
= (x - 2) {x (x - 5) + 2 (x - 5)}
= (x - 2) {(x - 5) (x + 2)}
P(x) = (x - 5) (x - 2) (x + 2)
For zeros, let p(x) = 0
=> (x - 5) (x - 2) (x + 2) = 0
Either
(x - 5) = 0
Or
(x - 2) = 0
Or
(x + 2) = 0
So, x = 5, 2, - 2

For what values of X does the graph of y=2x^5+15x^4 have a point of inflection?
Answer:
The values of x are 0 and -4.5
Step-by-step explanation:
To find the inflection point, we simply find the second derivative
Mathematically, that will be calculated as follows
1st derivative
10x^4 + 60x^3
2nd derivative
40x^3 + 180x^2
Equate these values to zero
40x^3 + 180x^2 = 0
x^2(40x + 180) = 0
x^2 = 0
or 40x = -180
x = 0
or x = -180/40 = -4.5
Is 2 a solution of 4x + 12= 4? Complete the statement. The equation is (true, false) when x = 2, so 2 (is, is not) a solution. WILL MARK BRAINLIEST
Answer:
The answer is false and is not
Explanation:
Given the equation - [tex]4x+12=4[/tex]
Substitute x = 2 in the equation
[tex]4(2)+12=4\\8+12=4\\20=4[/tex]
Thus, the equation is false. When the equation is false, meaning that the coordinate x-term isn't passed by the line. (Rather say that the point is not the part of the graph.)
The equation is false is our first answer.
If the equation is false, that means the given value is not part of the graph, thus making the x-value not the solution.
Answer:
The equation is FALSE when x=2, so 2 IS NOT a solution.

Answer:
588
Step-by-step explanation:
In a factor tree, I mostly like to look from down to up so that I can track down the non-square number. In a square number, there must be two factors that are exactly the same as each other, and when multiplied gives that square number.
So based on the 5 × 5, 2 × 2, and 7 × 7, we can tell that 25, 4 and 49 are all square numbers. We move up one level. Since the factors of 196 are square numbers, 196 is also a square number since it consists of 2² × 7².
We move another step up. 588 consists of 3 and 196. We know that 196 is a square number, but 3 is a prime number, which means that 3 only has a factor of 3 and itself. Thus, 588 is not a perfect square number since there should be a double factor for 3.
At o degrees Celsius, the volume of a gas is 22 liters. For each degree the temperature T (in degrees Celsius) increases, the volume V (in liters) of gas increases by two twenty fifths. Write an equation that represents the volume of the gas in terms of the temperature.
Answer:
[tex]V=\dfrac{2}{25}T+22[/tex]
Step-by-step explanation:
It is given that,
At 0 degrees Celsius, the volume of a gas is 22 liters. For each degree the temperature T (in degrees Celsius) increases, the volume V (in liters) of gas increases by 2/25.
If we take a cartesian coordinate, the line passes through (0,22). The slope of the line is 2/25.
The equation of a point-slope form is given by :
[tex]y-y_1=m(x-x_1)\\\\y-22=\dfrac{2}{25}(x-0)\\\\y-22=\dfrac{2x}{25}\\\\y=\dfrac{2x}{25}+22[/tex]
Here, x will be temperature and y will be volume. So,
[tex]V=\dfrac{2}{25}T+22[/tex]
Hence, the equation that represents the volume in terms of the temperature is [tex]V=\dfrac{2}{25}T+22[/tex]
Please refer to the following graph.

A store offers a 14% discount on a DVD. If the cost is discounted by $4.90, what is the original cost of the DVD?
Answer:
35
Step-by-step explanation:
Let's call the original price X
14% of x is equal to $4.90 to calculate 100% of the price we multiply 100 with 4.9 then divide it with 14
4.9 × 100 ÷ 14 = 35
