Answers
10220 meters Juanita swim in those 2 weeks.
Given that,
Juanita practiced her swimming for a competition by swimming 0.73 kilometers in the pool every day for two weeks.
We have to find Juanita swam how many meters in those two weeks? 1 km = 1,000 m
First, we multiply the number of days swam by the amount of kilometers swan each day.
0.73×2 week
0.73×14days
10.22
The kilometers are then multiplied by the conversion rate to convert them to meters.
10.22 kilometers multiplied by a 1000 m to m conversion factor results in 10220 m.
Therefore, 10220 meters Juanita swim in those 2 weeks.

Find the Area of the figure below, composed of a rectangle with two semicircles
removed. Round to the nearest tenths place.
Answer:
10
D(
PLEASE HELP 30 POINTS !!!!!!!!!!!!
Answers
Answer:
31.7 units²
Step-by-step explanation:
Since the two semicircles have the same radius, they have the same combined area as a full circle.
Rectangle: length 10; width 6
Circle: diameter 6; radius 3
area = area of rectangle - area of circle
area = LW - πr²
area = 10 × 6 - 3.14159 × 3²
area = 60 - 28.27431
area = 31.72569
Answer: 31.7 units²
For the spring picnic, Mr. Jones served 85 hot dogs to 50 people. Mr. Jones expects 68 people at the fall picnic. Which proportion could be used to find how many hot dogs Mr. Jones needs for the fall picnic?
Answers
If Mr. Jones served 85 hot dogs to 50 people the proportion of hot dogs is:
[tex]\frac{85}{50}\text{ hot dogs/person}[/tex]If he expects 68 people at the fall picnic, the amount of hot dogs he will need is the number of people multiplied by this proportion:
[tex]\text{hot dogs = 68p }\cdot\frac{85}{50}\text{ hot dogs/p}[/tex]Answer
The proportion that could be used to find how many hot dogs Mr. Jones will need for the fall picnic is 85/50
He will need 115.6 hot dogs (since the number of hot dogs is a whole number, He will have to buy 116 hot dogs)

Graph the line with the equation y = - 3/5x - 3
Answers
we have
y = - 3/5x - 3
To graph the line we need at least two points
so
Find the intercepts
step 1
Find the y-intercept (value of y when the value of x is zero)

Write and solve an equality to find the values of x for which the perimeter of the rectangle is less than 128
Answers
The value of x for which the perimeter of the rectangle is less than 128 is x < 30.
How to find the perimeter of a rectangle?The perimeter of a rectangle is the sum of the whole sides of a rectangle. Recall a rectangle is a quadrilateral with opposite sides equal to each other and opposite side parallel to each other.
Therefore, the perimeter of the rectangle is less than 128.
Hence,
perimeter of a rectangle = 2(l + w)
perimeter of a rectangle = 2l + 2w
where
l = side lengthw = widthTherefore,
2(x + 4) + 2x < 128
2x + 8 + 2x < 128
4x + 8 < 128
4x < 128 - 8
4x < 120
Therefore,
x < 30

Answers
The direct variation equation is: b) f = 30x.
The distance 420 newtons will stretch is: d) x = 14.
How to Write a Direct Variation Equation?The direct variation equation can be defined as y = kx, where k is the constant of proportionality, which is k = y/x, while x and y are the variables.
Let y represent the distance the spring is stretched, while x represents the force that is applied to the spring.
If a force (f) of 180 newtons is applied to stretch a distance of the spring (x) to 6 cm, therefore:
Constant of proportionality, k = 180/6
Constant of proportionality, k = 30
To write the direct variation equation, substitute k = 30 into f = kx:
f = 30x.
To find the distance (x) the spring will be stretched when 420 newtons was applied, substitute f = 420 into y = 30x:
420 = 30x
420/30 = 30x/30
14 = x
x = 14

Firstly, we need to locate the first point (2,-6)
That means a point 2 on the x axis and -6 on the y-axis.
Then, next locate the second point (-1,9)
That means a point -1 on the x axis and 9 on the y-axis.
Then lastly, join the two points.

How much you learned about the inverse, converse, and contrapositive of a conditional (if-then) statement, and how this can be applied in real life
Answers
A conditional statement can be written as:
[tex]p\rightarrow q[/tex]An example of this in real life is:
[tex]\text{If it rains then the floor gets wet.}[/tex]In this case:
p = it rains
q = the floor gets wet
The converse of that conditional is:
[tex]\begin{gathered} q\rightarrow p \\ \text{If the floor gets wet then it rains.} \end{gathered}[/tex]Notice that the conditional being true doesn't mean necessarily that its converse is true. For example, every time it rains the floor gets wet can be true, but the floor could get wet for other reasons, so the converse would not be true.
Also, the inverse of that conditional is:
[tex]\begin{gathered} \neg p\rightarrow\neg q \\ \text{If it does not rain then the floor does not get wet.} \end{gathered}[/tex]As we see, the inverse of a true conditional statement is not necessarily true.
And the contrapositive of that conditional statement is:
[tex]\begin{gathered} \neg q\rightarrow\neg p \\ \text{If the floor does not get wet then it does not rain.} \end{gathered}[/tex]Now, the contrapositive of a true conditional statement is always true. Notice that if every time it rains the floor gets wet, the only explanation for the floor not getting wet is that it does not rain.

[tex]\begin{gathered} \text{Range = Highest number - Smallest number } \\ =\text{ 11 - 4} \\ =7 \end{gathered}[/tex]Step 2 :
For the Standard Deviation,
We have that :
[tex]\text{Standard Deviation =}\frac{\sqrt[]{\sum ^{\infty}_{n\mathop=0}(X_{i\text{ }}-X)^2}}{n}[/tex]So, we need to evaluate using the following process,
[tex]\begin{gathered} \text{Mean, X = }\frac{4\text{ + 7 + 4 + 7 +7 + 9 + 11}}{7} \\ =\frac{49}{7} \\ =\text{ 7} \end{gathered}[/tex]Next, we evaluate the following :
Variance =
[tex]\frac{(4-7)^2+(7-4)^2+(4-7)^2+(7-7)^2+(7-7)^2+(9-7)^2+(11-7)^2}{7}[/tex]=
[tex]\begin{gathered} \frac{9\text{ + 9 + 9 + 0 + 0 + 4 + 4}}{7} \\ =\text{ }\frac{35}{7} \\ =\text{ 5} \end{gathered}[/tex]Next, we have that :
