Answer:
Cost of the refill mug = $8.95
Cost of each refills = $1.50
Sean bought a mug for $8.95
No. of refills he bought = (26.95 – 8.95)/1.50
= 18 /1.50
= 12

Three hikers started climbing with each hiker carrying 7.8 kilograms of weight. A fourth hiker joined them and they divided the total weight of hiking equipment evenly. How much did each hiker have after the 4th person joined? (Round your answer to two decimal places)
Answer:
5.85 kilograms
Step-by-step explanation:
We are told that Three hikers started climbing with each hiker carrying 7.8 kilograms of weight.
Thus, total weight carried by them = 7.8 × 3 = 23.4 kilograms
Now a fourth person joined them and they divided the weight equally.
Thus, each hiker will now carry;
23.4/4 = 5.85 kilograms
A colony of 15,000 bacteria doubles in size every 42 hours. What will the population be 84 hours from now?
Answer:
30,000
Step-by-step explanation:
You simply multipy the 15,000 by two since it is doubling. *4 is double of 42 which is why you would multiply by two.
Sam wants to take his drone on a car trip. An hour before they plan to leave, he realized that he forgot to charge the batteries last night. Drone's battery is at 25% and says it has 4.5 hours remaining. Which brand is Sam's battery most likely? How do you know?
Answer:
See explanation
Step-by-step explanation:
The question is incomplete..
The given parameters can only solve for the number of hours the battery can last if at full capacity.
Given
25% = 4.5 hours
Required
Determine the brand
First, we need to determine the full capacity (100%)
So, we have:
25% = 4.5 hours
100% = x
Cross Multiply
25% * x = 100% * 4.5 hours
Divide both sides by 25%
x = 4 * 4.5 hours
x = 18 hours
Hence, the battery at full capacity is 18 hours.
So, to answer the question, you need to check the given list of brands.
The brand closest to 18 hours answers the question

y = x2 + 4x + 4
y = 2x + 7
How many solutions?
Answer:
2 solutions
Step-by-step explanation:
Given the 2 equations
y = x² + 4x + 4 → (1)
y = 2x + 7 → (2)
Substitute y = x² + 4x + 4 into (2)
x² + 4x + 4 = 2x + 7 ( subtract 2x + 7 from both sides )
x² + 2x - 3 = 0 ← in standard form
(x + 3)(x - 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 1 = 0 ⇒ x = 1
Substitute these values into (2) for corresponding values of y
x = - 3 : y = 2(- 3) + 7 = - 6 + 7 = 1 ⇒ (- 3, 1 )
x = 1 : y = 2(1) + 7 = 2 + 7 = 9 ⇒ (1, 9 )
The 2 solutions are (- 3, 1 ) and (1, 9 )

If 2(x+3)^2=98 find x in this equation.
Answer:
x= 4 or -10
Step-by-step explanation:
Answer:
x = - 10, x = 4
Step-by-step explanation:
Given
2(x + 3)² = 98 ( divide both sides by 2 )
(x + 3)² = 49 ( take the square root of both sides )
x + 3 = ± [tex]\sqrt{49}[/tex] = ± 7 ( subtract 3 from both sides )
x = - 3 ± 7
Thus
x = - 3 - 7 = - 10
x = - 3 + 7 = 4

Write the equation of a line that passes through the point (-2,6) and is parallel to the line that passes through the points (0, – 4) and 3,2).
Answer:
Y = 9 + 2/3
Step-by-step explanation:
First, find the equation for the given points ((0, - 4) and (3, 2)). By graphing these points, I found that this equation was Y = -4 + 2/3.
Now, we can start to form the equation of the line you are trying to find. Because parallel lines must have the same slope, we know that the slope of the line will be 2/3. We can now use this slope to find the Y-intercept of the line. Add 2 to the X-coordinate and 3 to the Y-coordinate. By doing this you get the coordinates (0, 9). 9 is the slope of the second line.
Now we can make the equation you are trying to find. The answer is Y = 9 + 2/3 where 9 represents the Y-intercept and 2/3 represents the slope of the line.
Hope this helps! Let me know.

A town's chamber of commerce printed a map of the buisiness district. The map is 12 inches square, and 1 inch on the map represents an actual distance of 300 feet. A larger version of the same map of the business district is printed with the side length of %50 longer than the side length of the previous map. On the larger map, what is the actual distance ,in feet, represented by 1 inch?
On the larger map, 1 inch represents an actual distance of 300 feet.
In the original map, 1 inch represents an actual distance of 300 feet.
Since the map is 12 inches square, the side length of the map is 12 inches. Therefore, the actual distance represented by the entire map is 12 inches * 300 feet/inch = 3600 feet.
In the larger version of the map, the side length is 50% longer than the original map. This means the side length of the larger map is 12 inches + (50% * 12 inches) = 12 inches + 6 inches = 18 inches.
To determine the actual distance represented by 1 inch on the larger map, we can set up a proportion:
12 inches (original map) corresponds to 3600 feet (actual distance)
1 inch (larger map) corresponds to x feet (actual distance)
Using cross-multiplication, we find that x = (1 inch * 3600 feet) / 12 inches = 300 feet.
1 inch on the larger map represents an actual distance of 300 feet.

Find the measures of the complementary angles that satisfy each case.
The angles have equal measure.
Answer:
45 degrees and 45 degrees
Step-by-step explanation:
45+45=90
The measure of the two complementary angles will be 45.
What are complementary angles?Complementary angles are those whose combined angle is exactly 90 degrees. The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
Given that the two angles are complementary to each other.
The complementary angles are the angles having the sum of 45 degrees. The two complementary angles will be calculated as,
45 + 45 = 90
Here one angle is 45 and the other angle is also 45 and the sum of the angles is 90.
Therefore, the measure of the two complementary angles will be 45.
