Help me please:) you will get 16 points. Help with number 5
Answer:
you would add a /1 under the 7 so it would be 7/1
Step-by-step explanation:
Answer:
84/12
Step-by-step explanation:
since 7 is a whole, you need to make it a improper fraction so its easier to subtract. We need to do this by making sure the denominator stays the same which is 12.Then do 7x12. you get 84, so 84/12. Then its easier to solve.

Pharmex is a chain of drugstores that operate around the country. To see how effective its advertising and other promotional activities are, the company has collected data from 50 randomly selected metropolitan regions. In each region, it has compared its own promotional expenditures and sales to those of the leading competitor in the region over the past year. There are two variables: "Promote" reflects Pharmex’s promotional expenditures as a percentage of those of the leading competitor, and "Sales" reflects Pharmex’s sales as a percentage of those of the leading competitor. A portion of the data appears below. Show all work.

A.) From the resulting plot, tbe slope of the graph is positive, hence, we can conclude that there exist a positive relationship between the variables 'promote' and 'sale'.
The linear trend line gives the best fit for the data with a correlation Coefficient, R value of 0.5935
The R² value is 0.3522. R² is the Coefficient of determination which gives the percentage of explained variation. For this data, about 35% of variation in sales is given by the best fit line.

What is the value of j?
Group A is on the north side of the fire and is 800 ft away from group B and 900 feet away from group C. Group A knows that the angle between its two adjacent sides is 89.6. “
The emergency responders want to properly inform the nearby towns of the danger proximity. They will need all three angles. To do this they need some additional information. The emergency responders need to know the angle of Group B and Group C. They also need to know the distance between Groups B and C.
Answer:
1. Length BC is 1200 ft
2. Angle B is 48.6°
3. Angle C is 41.8°
Step-by-step explanation:
1. Determination of the length BC
Side opposite C = c = 800 ft
Side opposite B = b = 900 ft
Angle A = 89.6°
Side opposite BC = a =?
Using cosine rule, we can obtain length BC as follow:
a² = b² + c² – 2bc CosA
a² = 900² + 800² – 2 × 900 × 800 × Cos89.6
a² = 810000 + 640000 – 1440000 × 0.007
a² = 1450000 – 10080
a² = 1439920
Take the square root of both side
a = √1439920
a ≈ 1200 ft
Thus, length BC is 1200 ft
2. Determination of angle B
Side opposite B = b = 900 ft
Side opposite A = a = 1200 ft
Angle A = 89.6°
Angle B =?
Angle B can be obtained by using sine rule as follow:
a / Sine A = b / Sine B
1200 / Sine 89.6° = 900 / Sine B
Cross multiply
1200 × Sine B = 900 × Sine 89.6°
1200 × Sine B = 900
Divide both side by 1200
Sine B = 900/1200
Sine B = 0.75
Take the inverse of Sine
B = Sine¯¹ 0.75
B = 48.6°
Thus, angle B is 48.6°
3. Determination of angle C
Side opposite C = c = 800 ft
Side opposite A = a = 1200 ft
Angle A = 89.6°
Angle C =?
Angle C can be obtained by using sine rule as follow:
a / Sine A = c / Sine C
1200 / Sine 89.6° = 800 / Sine B
Cross multiply
1200 × Sine C = 800 × Sine 89.6°
1200 × Sine C = 800
Divide both side by 1200
Sine C = 800/1200
Sine C = 0.6667
Take the inverse of Sine
C = Sine¯¹ 0.6667
C = 48.6°
Thus, angle C is 41.8°

In speech class, Carolyn needs at least a B + to keep her financial aid. To earn a B+, the average of her four speeches must be at least an 85. On the first 3 she scored 85, 77, and 81. Determine the minimum score speech to get a B+.
Answer:
The minimum score speech to get a B+ is 89.Step-by-step explanation:
Average of the first 3 = 85 + 77 + 81 / 3
= 243 / 3
= 81
The fourth score ( to get 85 ) = 81 + 89
= 170 / 2
= 85
Answer:
97
Step-by-step explanation:
Relative to the average she wants, Carolyn's scores are ...
85-85 = 0
77-85 = -8
81-85 = -4
Carolyn's score total is -8-4 = -12 points from the average she wants, so she must get 85+12 = 97 on her speech to achieve a B+ average.
_____
Check
With a 97, Carolyn's average would be ...
(85 +77 +81 +97)/4 = 340/4 = 85

Jamal is comparing his transportation options for an upcoming trip. He's considering a rental car and a taxi service. Based on his planned routes
during his trip, he expects a taxi service would cost about $128. Jamal could also get a rental car for a dally rate and unlimited miles. If Jamal's
trip will last 4 days and he expects to pay about $24 for gas, which graph shows the range of car rental rates that would be cheaper than the taxi
service?
The range of rental car rates that would be cheaper for Jamal than the taxi service and the graph of inequality x<26 is shown.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
Let's suppose the rental car rate is:
$x per day
Number of days of Jamal's trip = 4 day
He expects to pay $24 for gas (for car rent)
He expects a taxi service would cost about $128
Inequality can be modelled:
128 > 24 + 4x
4x < 104
x < 26
Thus, the range of rental car rates that would be cheaper for Jamal than the taxi service and the graph of inequality x<26 is shown.

Which system models the height of the tennis ball and the height of the dog's mouth over time? h = 4.5t + 18 and h = -16t2 + 1.5t + 21 h = 18t + 4.5 and h =-16t2 + 21t + 1.5 h = -16t2 + 4.5t + 18 and h = -16t2 + 1.5t + 14 h = -16t2 + 18t + 4.5 and h = -16t2 + 21t + 1.5
Answer:
the first answer is d and the second one is c
Step-by-step explanation:
edge
The height of the tennis ball and the height of the dog's mouth over time are h = 4.5t + 18 and h = -16t2 + 1.5t + 21 respectively. Therefore, the correct option is option A.
What is height?Height is a measurement of vertical distance, or how high or something someone is (how tall they are). For instance, "The altitude of that structure is 50 m" and "The height of such an aircraft in-flight is roughly 10,000 m". Christopher Columbus, for instance, has a height of 5 feet 2 inches.
Height is more frequently referred to as altitude when describing the vertical position from sea level. Additionally, elevation (height over sea level) is known as altitude if the point is connected to the Earth. The height of the tennis ball and the height of the dog's mouth over time are h = 4.5t + 18 and h = -16t2 + 1.5t + 21 respectively.
Therefore, the correct option is option A.
