Liz has turtles that triple every month. and Steven has turtles that double every month. If Liz has 7 turtles at the same time that Steven has 5 turtles. then in how many turtles after 6 months do they have in total?
The number of turtles they will have after 6 months is =1,893 turtles
Calculation of total turtleNumber of turtles owned by Liz every month =
first month = 7
second month= 7×3 = 21
third month = 21× 3 = 63
fourth month = 63 × 3 = 189
Fifth month = 189 × 3 = 567
Sixth month = 567 × 3 = 1701 turtles
Number of turtles owned by Steven every month =
first month = 6
second month = 6 × 2 = 12
third month = 12× 2 = 24
Fourth month = 24 × 2 = 48
Fifth month = 48 × 2 = 96
Sixth month = 192 turtles
Therefore total turtle owned by both Liz and Steven=
1701 + 192 = 1,893 turtles

It appears the graph goes through (0,3) and (5,6)
If so, then you have the correct slope and y intercept.
The formula is [tex]C = \frac{3}{5}n+3[/tex] which is the same as writing C = (3/5)n+3
Don't forget about the parenthesis around the 3/5.
We can verify this by plugging in n = 0 and you should get C = 3.
Also, if n = 5 then it leads to C = 6.
Two similar triangles have a pair of corresponding sides of length 12 meters and 8 meters.
The larger triangle has a perimeter of 48 meters and an area of 180 square meters. Find the
perimeter and area of the smaller triangle.
Answer:
32 m, 80 m^2
Step-by-step explanation:
Ratio of their sides = 12 : 8 = 3 : 2
Ratio of their perimeter = 3 : 2
so 48 : perimeter of smaller triangle = 3 : 2
Perimeter of smaller triangle = 48 * 2 / 3 = 32 m
Ratio of their areas = 3^2 : 2^2 = 9 : 4
so 180 : area of smaller triangle = 9 : 4
Area of smaller triangle = 180 * 4 / 9 = 80 m^2

month's rent, and a $650 security deposit. You also have upfront costs of $126 for
a year of tenant insurance, $95 hookup fee for phone and internet, and $80 TV
hookup fee. What is the total amount you need to begin renting the apartment?
The total amount need to begin renting the apartment is $2281.
What is rent?An agreement where a fee is paid for the temporary use of a good, service, or property owned by another is known as renting, sometimes known as hiring, or letting.
We have,

The graph shows a point at (4,1) and a line segment with endpoint at (2,2) and (6,2) This line segment will be dilated with the point of dilation at (4, 1) and a scale factor of 2. What is the 2-coordinate of
one of the endpoints of the dilated segment?
Dilation involves changing the size of a figure
The endpoints of the image are (0,3) and (8,3)
How to determine the coordinates of the imageThe coordinates of the pre-image are give as:
(2,2) and (6,2)
The scale factor is given as:
k = 2
The center of dilation is given as:
(a,b) = (4,1)
The coordinates of the image are then calculated as:
(x,y) = (k(x -a) + a, k(y -b) + b)
For (2,2), we have:
[tex](x,y) \to (2(2 -4) + 4, 2(2 - 1) + 1)[/tex]

In an experiment to learn whether Substance M can help restore memory, the brains of 20 rats were treated to damage their memories. First, the rats were trained to run a maze. After a day, 10 rats (determined at random) were given M and 7 of them succeeded in the maze. Only 2 of the 10 control rats were successful. The two-sample z test for "no difference" against "a significantly higher proportion of the M group succeeds"
a) should not be used because the Large Counts condition is violated.
b) gives z = 2.25, P < 0.02
c) gives z = 2.60, P < 0.005
d) should not be used because the Random condition is violated
e) gives z = 2.25, P < 0.04 but not < 0.02
The number of rats in the sample are less than 30, therefore, according
to the central limit theorem, cannot approximate the population.
Response:
a) Should not be used because the Large Counts Condition is violated
Which condition are necessary for the hypothesis test?The proportion of the rats given M that succeeded, [tex]\hat p_1[/tex] = 7 ÷ 10 = 0.7
The proportion of the control rats that succeeded, [tex]\hat p_2[/tex] = 2 ÷ 10 = 0.2
H₀: [tex]\hat p_1[/tex] = [tex]\hat p_2[/tex]
Hₐ: [tex]\hat p_1[/tex] > [tex]\hat p_2[/tex]
The z-test formula for the difference between two proportion is given as follows;
[tex]Z= \mathbf{\dfrac{\hat{p}_1-\hat{p}_2}{\sqrt{\hat{p} \cdot (1-\hat{p})\left (\dfrac{1}{n_{1}}+\dfrac{1}{n_{2}} \right )}}}[/tex]
Where;
[tex]\hat p = \dfrac{7 + 2}{10 + 10} = 0.45[/tex]
[tex]Z=\dfrac{0.7-0.2}{\sqrt{0.45\times (1-0.45) \times \left (\dfrac{1}{10}+\dfrac{1}{10} \right )}} \approx \mathbf{ 2.25}[/tex]
p = 1 - p(z < 2.25) = 1 - 0.9878 = 0.0122
However, the number of rats in the sample, n are less than 30
Therefore;

Answer:
A = 70
B = 110
C = 110
Step-by-step explanation:
A is opposite of the 70 degree angle, and vertical angles are equal, so it is also 70 degrees.
A straight line is 180 degrees, so 70 + B = 180, making B = 110 degrees.
Both of these rules apply for C, making it also 110 degrees.

A triangle has an area of 13.5 square miles and a height of 4.5 miles. What is the length
of the base?
Answer:
6 miles
Step-by-step explanation:
Area is :
[tex]A = \frac{1}{2} hb[/tex] OR [tex]A = \frac{hb}{2}[/tex]
So base is :
[tex]b = 2 \frac{A}{h}[/tex]
Substituting values given:
b = 2 × (13.5÷4.5)
b = 2×3
b=6
Answer:
the length of the base= 6miles
Step-by-step explanation:
Area of triangle =1/2 *Base*Hight
Now we sub the values in the formula:
13.5 = 1/2 * (length of the base) * 4.5
length of the base = (2 * 13.5)/4.5
length of the base = 6 miles

Surface area help I am struggling
Answer:
Total Surface Area: 65.97 cm²
Lateral Surface Area: 37.70 cm²
Step-by-step explanation:
You can solve for the surface area without the height or you can solve for the height and then find the surface are, either way is easy.
Lets first solve without the height. We will solve the surface area with the radius and slant height.
Total Surface area of cone formula: πr (r + s)
Curved surface are formula: πrs
Substitute the values in the picture with the formula
Slant height: 4
Radius: 3
πr (r + s)
π(3)(3 + 4)
(3.141593)(3)(3 + 4)
=9.424778(3 + 4)
=(9.424778)(7)
=65.973446
65.973446 rounded to the nearest hundredth is 65.97
TSA = Total Surface Area
TSA = 65.97 cm²
Now to find the curved surface area or some people call it the Lateral Surface Area
Formula: πrs
Radius: 3
Slant Height: 4
π(3)(4)
(3.141593)(3)(4)
=(9.424778)(4)
=37.699112
37.699112 to the nearest hundredth is 37.70
CSA = Curved Surface Area
CSA = 37.70 cm²
If you choose to compute the height (h) the you have to know both the radius (r) and the slant height (s):
Formula: height (h) = √s² - r²
Slant height = s = 4
Radius = r = 3
Height = h = ?
Now substitute the values into the formula
h = √s² - r²
h = √4² - 3²
h = √16 - 9
h = √7
h = 2.64575131
Height: 2.64575131 cm
Now it's time to find the surface area and curved surface area, now that you have the height:
Surface area formula given height and radius: πr(r + √(r² + h²))
Substitute the values
Height: 2.64575131
Radius: 3
πr(r + √(r² + h²))
π(3)(3 + √(3² + 2.64575131²))
TSA = (3.141593)(3)(3 + √(3² + 2.64575131²)
TSA = 9.424778(3 + √(3² + 2.64575131²)
TSA = 9.424778(3 + √(9 + 7)
TSA = 9.424778(3 + √(16)
TSA = 9.424778(3 + 4)
TSA = 9.424778(7)
TSA = 65.973446
TSA = 65.97
Next, time to find the Curved surface area:
Formula: CSA = πr√(r² + h²)
CSA = πr√(r² + h²)
Substitute the values into the formula
Radius: 3
Height: 2.64575131
Slant Height: 4
CSA = πr√(r² + h²)
CSA = π(3)√(3² + 2.64575131²)
CSA = 9.424778√(3² + 2.64575131²)
CSA = 9.424778√(9 + 7)
CSA = 9.424778√(16)
CSA = 9.424778(4)
CSA = 37.699112
CSA = 37.70
So, we can conclude that the Total Surface Area is 65.97 and the Lateral Surface Area is 37.70.
Which of the following statements about variables is false? a. Mathematical operations can be performed on a variable. b. The variable will always be the letter x. c. A mathematical statement can include more than one variable. d. A variable is a letter used to represent an unknown quantity.
Answer:
b. The variable will always be the letter x (false)
Step-by-step explanation:
Variables can be any letter or symbol. The letter x is often used as a variable, but that is not the only choice. Many formulas, for example, make use of variables that have letters reminding you what they stand for.
For example, the formula ...
A = 1/2(b1 +b2)h
uses the variables A, b1, b2, and h to represent area, base-1, base-2, and height, respectively. The letter x is not used at all.
