To make 5 pizzas, 1/2 cup of flour is used a. How much flour is needed to make one pizza? b.. How many cups of flour are needed to make 1 dozen pizzas? (1 dozen - 12) c. How many pizzas can you make with 5 2/3 cups of flour?
Answer:
for a single pizza 1/10 a cup
for 12 pizzas 1 1/5 a cup
you can make 56 pizzas with 5 2/3 cups.
Step-by-step explanation:
for 5 pizzas you need 1/2 cup of flour, so to find out how much you'll need for a single pizza you'll need to divide it with 5. 1/2÷5=1/10
for a dozen pizzas you'll need to multiply that with 12. 1/10x12=12/10=1 1/5
Then to find out how many can we make with 5 2/3 cups we'll divide it with that 1/10
56/10÷1/10= 56 pizzas

Two sensors are spaced 700 feet apart along the approach to a small airport. When an aircraft is nearing the airport, the angle of elevation from the first sensor to the aircraft is 20°, and from the second sensor to the aircraft is 15°. Determine how high the aircraft is at this time.
Answer:
711 ft (nearest foot)
Step-by-step explanation:
Create two equations using trig ratios and the information given (refer to the attached diagram). Equate the equations and solve.
First equation
Let y = horizontal distance between sensor 1 and the aircraft
Let h = height of aircraft above the ground
Using the tangent trig ratio:
[tex]\mathsf{\tan(\theta)=\dfrac{opposite \ side}{adjacent \ side}}[/tex]
Given:
angle = 20°side opposite the angle = hside adjacent the angle = y[tex]\implies \mathsf{\tan(20)=\dfrac{h}{y}}[/tex]
Rearrange to make y the subject:
[tex]\implies \mathsf{y=\dfrac{h}{\tan(20)}}[/tex]
Second equation
Let y + 700 = horizontal distance between sensor 2 and the aircraft
Let h = height of aircraft above the ground
Using the tangent trig ratio:
[tex]\mathsf{\tan(\theta)=\dfrac{opposite \ side}{adjacent \ side}}[/tex]
Given:
angle = 15°side opposite the angle = hside adjacent the angle = y + 700[tex]\implies \mathsf{\tan(15)=\dfrac{h}{y+700}}[/tex]
Rearrange to make y the subject:
[tex]\implies \mathsf{y=\dfrac{h}{\tan(15)}-700}[/tex]
Now equate the 2 equations and solve for h:
[tex]\implies \mathsf{\dfrac{h}{\tan(20)}=\dfrac{h}{\tan(15)}-700}}[/tex]
[tex]\implies \mathsf{700=\dfrac{h}{\tan(15)}-\dfrac{h}{\tan(20)}}[/tex]
[tex]\implies \mathsf{700=\dfrac{h\tan(20)-h\tan(15)}{\tan(15)\tan(20)}}[/tex]
[tex]\implies \mathsf{700=\dfrac{\tan(20)-\tan(15)}{\tan(15)\tan(20)}h}[/tex]
[tex]\implies \mathsf{h=\dfrac{700\tan(15)\tan(20)}{\tan(20)-\tan(15)}}[/tex]
[tex]\implies \mathsf{h=710.9678247...}[/tex]
Therefore, the height of the aircraft is 711 ft (nearest foot)

It is commonly believed that the mean body temperature of a healthy adult is 98.6 ∘ F 98.6∘F . You are not entirely convinced. You believe that it is not 98.6 ∘ F 98.6∘F . You collected data using 36 healthy people and found that they had a mean body temperature of 98.23 ∘ F 98.23∘F with a standard deviation of 1.05 ∘ F 1.05∘F . Use a 0.05 significance level to test the claim that the mean body temperature of a healthy adult is not 98.6 ∘ F 98.6∘F . a) Identify the null and alternative hypotheses? H 0 H0 : μ = H 1 H1 : μ < b) What type of hypothesis test should you conduct (left-, right-, or two-tailed)? left-tailed right-tailed two-tailed c) Identify the appropriate significance level. d) Calculate your test statistic. Write the result below, and be sure to round your final answer to two decimal places. e) Calculate your p-value. Write the result below, and be sure to round your final answer to four decimal places. f) Do you reject the null hypothesis? We reject the null hypothesis, since the p-value is less than the significance level. We reject the null hypothesis, since the p-value is not less than the significance level. We fail to reject the null hypothesis, since the p-value is less than the significance level. We fail to reject the null hypothesis, since the p-value is not less than the significance le

5. Which of the following best describes a negative linear association?*
A Variables have no relation to each other when plotted.
B As one variable increases so does the other
CA data set that includes both negative and positve numbers
D As one variable decreases, the other increases
D. As one variable decreases, the other increases.
A negative linear association means that as one variable decreases, the other variable increases. This indicates an inverse relationship between the two variables.
As the value of one variable decreases, the value of the other variable tends to increase consistently and vice versa. This pattern can be observed when plotting the data points on a scatter plot, where the points tend to form a downward sloping line.
Option A is incorrect because a negative linear association implies a clear relationship between the variables, unlike no relation. Option B is incorrect because it describes a positive linear association, where both variables increase together.
Option C is incorrect because the presence of both negative and positive numbers does not necessarily indicate a negative linear association. The key characteristic of a negative linear association is the inverse relationship between the variables as described in option D.

What would be the slope of a line that is PARALLEL to the following?
y=-4x +11
If your answer is a fraction please enter it as a decimal.
Parallel Slope =
(Someone please help me I don’t understand this helpppp)
Answer:
The slope would be -4
Step-by-step explanation:
Since the two lines are parallel, the slopes would have to be the same because the lines can't intersect. In an equation of a line, the number before the "x" is always the slope.
Answer:
The slope of a line that is parallel to y=-4x+11 is m2=-4
Step-by-step explanation:
Parallel lines
The equation of a line of slope m and y-intercept b can be expressed as:
y=mx+b
The equation of the given line is
y=-4x+11
Which means its slope is m1=-4
Two parallel lines are defined to have the same slope. If m2 is the slope of a parallel line, then:
m2=m1=-4
Then, the slope of a line that is parallel to y=-4x+11 is m2=-4

C(n)=1/500 n^2-n +200 where is n is the number. does the cost have a minimum or maximum value explain
Answer:
minimum
Step-by-step explanation:
The sign of the leading coefficient of a quadratic tells you whether its graph opens upward or downward. Here, the sign of 1/500 is positive, so the graph opens upward. The function will have a minimum.
_____
Additional comment
For even-degree polynomials (quadratic = degree 2), the general shape of the curve will be ∪ or ∩. The latter will result from a negative leading coefficient.
For odd-degree polynomials, the general shape of the curve will be / or \. Again, the latter results from a negative leading coefficient.
These facts can help you identify the end-behavior of a polynomial function.
