Answer:
Square root of 85
Step-by-step explanation:
We can envision the segment AB as the hypotenuse of a right triangle with a height of 6 units and a length of 7 units. We can use the Pythagorean Theorem to solve for the length of segment AB which is similar to distance formula.
6^2 + 7^2 = c^2
36 + 49 = c^2
c^2 = 85
c = Square root of 85.

As a reward for winning a math competition, 26 students in the 7th grade visited a theme park. On one ride, 3 equal groups of students could be seated and 2 students were left over. Write and solve an equation to find how many students could be seated in each group.
Answer: in each group, there are 8 students.
Step-by-step explanation:
We have a total of 26 students.
If we separate them into 3 equal groups (suppose that each group has X students) and leave 2 students left, we will have the relation:
3*X + 2 = 26
This means that 3 times the number of students in each group, plus the two students leftover must be equal to the initial number of students.
Now we can solve this for X.
3*X + 2 = 26
3*X = 26 - 2 = 24
X = 24/3 = 8
X = 8
This means that in each group there are 8 students.

Step-by-step explanation:
A family has a hybrid car that gets 40 miles per gallon (mpg) and a pickup truck that gets 17 mpg. They drive at least 500 miles per week using both vehicles but don't want to use more than 20 gallons of gas. Make a recommendation for using each vehicle. Part A Write an expression that represents the total amount of gasoline used. Then write an inequality to show the maximum amount of gasoline that the family wants to use. Define the variables and list any constraints on the variables.
Answer:
[tex]Z=x+y[/tex]
[tex]x+y<20[/tex]
Step-by-step explanation:
Let the gallons of fuel used in the hybrid per week car be [tex]x[/tex] and [tex]y[/tex] be the number of gallons used in the pickup truck per week.
Number of miles driven using both vehicles is at least 500 per week. The inequality that represents the number of miles driven is.
[tex]40x+17y\geq 500[/tex]
The expression of total amount of fuel used would be [tex]Z=x+y[/tex].
Now the sum of the fuels used in both the cars is more than 20 gallons per week. The inequality that represents the total amount of gasoline used is
[tex]x+y<20[/tex]

The level of the tide in a harbor changes from 9 1/4 to 4 1/2 above sea level over a period of 3 1/4 h. Whatbis the rate of change in the tide level over this period of time?
Answer:
The answer should be -19/13 per hour. I think, I'm not completely sure.
Step-by-step explanation:
Find the difference of 9 1/4 and 4 1/2
divide by 3 1/4
simplify
4 1/2 - 9 1/4 = -19/4
-19/4 divided by 13/4 = -76/52
-76/52 = -38/26 = -19/13
So the answer should be -19/13 per hour.
The requried rate of change in the tide level over this period of time is 19/13h.
What is the rate of change?Rate of change is defined as the change in value with rest to the time is called rate of change.
To find the rate of change, we need to divide the change in the tide level by the time elapsed:
Change in tide level = 37/4 - 9/2 = 37 - 18/4 = 19/4
Time elapsed = 13/4 h
Rate of change = Change in tide level ÷ Time elapsed
= 19/4 ÷ 13/4
= 19/13 h
So, the rate of change in the tide level over this period of time is 19/13h.

16. Point B(3, 2) translated (right, up) = (-2, 3) will be ...
B' = B + (-2, 3) = (3, 2) +(-2, 3) = (3 -2, 2 +3)
B' = (1, 5)
Note: (x, y) coordinates are (right, up). So, in translation problems it is important to pay attention. Often, the up/down translation is listed before the left/right translation. If you're not paying attention, you may inadvertently reverse the numbers that need to be added to the coordinates to do the translation.

-5
-3
-5/6
-1/3
(also i have other questions if you can view the ones on my profile and answer them tysm)
Answer:
The slope is -3.
Step-by-step explanation:
The slope is equal to the change in y over the change in x.
First, we take the two y values, -2 and -8, and subtract the SECOND from the FIRST: -2 - (-8) = -2 + 8 = 6 (= change in y)
Second, we take the two x values, 5 and 7, and subtract the SECOND from the FIRST: 5 - 7 = -2 (= change in x)
Finally, we make a fraction, the change in y over the change in x:
6/-2 = -3
The slope is -3.
the ratio of the measures of the sides of a triangle is 2:10:7 find the length of each side of the perimeter of the triangle is 228 meters
Answer:
Length of side 1 = 24 m
Length of side 2 = 120 m
Length of side 3 = 84 m
Step-by-step explanation:
The ratio of each side of triangle is: 2:10:7
Perimeter of triangle = 228 meters
We need to find the length of each side.
Let the common ratio be x
We can write the ratios as: 2x,10x and 7x
Length of side 1 = 2x
Length of side 2 = 10x
Length of side 3 = 7x
Using the formula: [tex]Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle\\[/tex]
Putting values and finding x:
[tex]Perimeter\:of\:triangle=Sum\:of\:all\:sides\:of\:triangle\\\\228=2x+10x+7x\\19x=228\\x=\frac{228}{19}\\x=12[/tex]
So, we get value of x=12
Now, finding length of each side by putting x=12:
Length of side 1 = 2x =2(12) = 24
Length of side 2 = 10x = 10(12) = 120
Length of side 3 = 7x = 7(12) = 84
So,
Length of side 1 = 24 m
Length of side 2 = 120 m
Length of side 3 = 84 m

mowing lawns earns $10.00 for 1 hour and $42.00 for 5 hours. what is the slope
Answer:
The slope is $8 per hour
Step-by-step explanation:
Here, we want to get the slope of the relation
Mathematically, that will be;
m = y2-y1/x2-x1
Where ; (no of hours, money) represents each point
Thus, we have it that
m = (42-10)/(5-1) = 32/4 = $8/ hour
a bacteria culture starts with 420 bacteria and grows at a rate proportional to its size. after 6 hours there will be 2520 bacteria.
Population growth rate of the bacterial culture can be expressed as a function of time as N = [tex]e^{kt + C}[/tex]
Step-by-step explanation:
If we assume the number of bacteria at any time (t) is (N). Then, the population of bacterial culture at that time is given by
N = N (t)
It is also given that the rate at which the bacterial culture will grow is proportional to its size. So, the growth rate is given by
dN/dt ∝ N
Removing the sign of proportionality, we get a constant
dN/dt = KN
We get
∫1/N dt = ∫K dt
After integration
ln N = Kt + C
N = [tex]e^{kt + C}[/tex]

Answer:
12 pieces
Step-by-step explanation:
There are four 25 cents in a dollar, as a dollar is 100 cents and 100 divided by 25 is four. So as 3 pieces cost 25 cents, multiply 3 by 4 which is 12.
12 pieces of gum would cause $1.00
Answer:
You can get 12 pieces of gum.
Step-by-step explanation:
3 pieces is 25, right? so now to make a dollar you can have four of 25 cents, so multiply, 3x4. You get 12. so you can buy 12 pieces of gum.
