Answer:
91 boys
Step-by-step explanation:
Given that the ratio of boys to girls = 7 : 2 = 7x : 2x ( x is a multiplier )
There are 65 more boys than girls , thus
7x = 2x + 65 ( subtract 2x from both sides )
5x = 65 ( divide both sides by 5 )
x = 13
There are 7 × 13 = 91 boys in the group
The populations P (in thousands) of a certain city from 2000 through 2007 can be modeled by P = 1674.7e^kt, where t represents the year, with t = 0 corresponding to 2000. In 2006, the population of the city was about 1,920,000. Find the Value of K
Answer:
k = 0.02278
Step-by-step explanation:
Given that:
The population P = 1674.7e^kt
where;
t represents the year,
if year 2000 represents t = 0
Then, the year 2007 represents = 7; &
year 2006 represents = 6
In 2006, population recorded in the city was about 1,920 thousand
Therefore;
[tex]1920 = 1674.7e^{(k\times 6)[/tex]
Taking the logarithm of both sides, we get:
[tex]\mathtt{ In}(1920) = \mathtt{ In} ( 1674.7)+ 6k[/tex]
7.560080465= 7.423389324 + 6k
7.560080465 - 7.423389324 = 6k
0.136691141 = 6k
k = 0.136691141/6
k ≅ 0.02278

Erin opened a savings account with $50. She deposited $35.50 into the account every month until she had a total of $653.50. Which equation could be used to find m, the number of months she made deposits into the account?
653.5=50+35.5m
653.5+50=35.5m
653.5=50−35.5m
653.5÷50=35.5m
Answer:
The first answer choice(653.5=50+35.5m)
Step-by-step explanation:
Since she deposited 35.5 each month, that would be variable m, and there was already 50 in her account, making it a constant number 50.
Answer:
653.5 / 50 = 35.5
Step-by-step explanation:
You have to divide 653.5 by 50 to get the amount of months she made deposits into her account.

10) The line FG is a diameter of the circle with centre C (6, 1). Given F is (2.-3), find the coordinates of G.
Answer:
Coordinates of the endpoint g is (10,5)
Step-by-step explanation:
The coordinates of a midpoint can be found using the formula;
(x,y) = (x1 + x2)/2 , (y1 + y2)/2
In this case, we have the mid point but we want to get the end point
Thus;
(6,1) = (x1 + 2)/2 , (y1-3)/2
x1 + 2 = 2(6)
x1 + 2 = 12
x1 = 12-2
x1 = 10
y1 - 3 = 2(1)
y1 -3 = 2
y1 = 2 + 3
y1 = 5
The coordinates of G are (10,5)
y 3x + 8
(3,17) is the ordered pair a solution ? Please show work
Answer:
yes
Step-by-step explanation:
y = 3(3) + 8
y = 9 + 8
y = 17
Answer:
Yes, (3, 17) is a solution.
Step-by-step explanation:
In an ordered pair the first variable is x, and the second is y (x, y), so we can take the x and y of the given point and put it into our equation.
y=3x+8
we replace y with our given y (17)
and our x with our given x (3)
17=3(3)+8
now solve
17=9+8
17=17
Both sides are equal so yes, (3, 17) is a solution.

Make a sketch of a linear relationship with slope 3 that is not a proportional relationship show how you know hay slope is 3 write an equation for the line
Answer:
A proportional relationship is something like:
y = k*x
Where k is the constant of proportionality
And a linear relationship is something like:
y = a*x + b
Is easy to see that if:
a = k, and b = 0, this would be a proportional relationship.
Then if we want to have a slope equal to 3, but this must not be a proportional relationship, we must only have b different than 0.
This could be something like:
y = 3*x + 1
The graph of this is:
A linear non - proportional relationship could be written with as a slope - intercept with a non - zero intercept value. One such relationship with a slope of 3 can be expressed thus :
y = 3x + 5Here, the linear relationship, has a slope value of 3 and an intercept value of 5. The function cannot be proportional due to the presence of a non-zero constant
Hence, Using a graphing calculator, the sketch of the linear relationship is attached.

This is the true statement ΔADB≅ΔBDC
What are congruent triangles?Two triangles are said to be congruent if their corresponding sides and angles are equal.
In Δ ADB,
∠D = 90°
∠B = 90°/2 = 45°
∠A = 180° - 90° - 45° = 45°
So ΔADB is 90-45-45 triangle.
In ΔBDC,
∠ ? = 90° This is supplementary to Angle D.
∠ B = 90°/2 = 45°
∠ C = 180° - 90° - 45° = 45°
So, ΔBDC is also a 90-45-45 triangle.
Hence, ΔADB≅ΔBDC

The data is skewed right and it increases at ages 6-8 and progresses.
Step-by-step explanation:
Answer:
The histogram is skewed left meaning that the median will be more than the mean of the data. As the study goes onward in terms of age, more and more children are studied to play at least an hour a week of video games. Barley any children below the age of 5 play video games for at least an hour a week, but once they hit the age of 6, more and more kids are playing video games. Kids aged fifteen to seventeen have the most amount of kids that do play at least an hour of video games per week. In a graph, this may show a J-shaped curve that starts low, then has a large increase to eventually level off and begin gradually getting larger as the ages increase.
