2. Once again you just have to find the areas of the individual shapes and then add them together. So, 8×4 added to (4+4)×4 added to 12×12. So the area would be 32+32+144 which is 208.
3. First work out the triangles area: (12-8)×((16-10)/2) which equals 12. And then add it to the rectangles area: 16×8 which is 128. So the area is 140.
4. Find out the area of the circles: 3.14×1.5^2 which is 7.065. This is the area for a full circle and as there is 4 halves in the picture, multiply this number by 2, giving a total circle area of 14.13. Then simply add the square area which is 3×3. So the total area is 23.13.
It's the same for the last two. Seperate 5 into a triangle, long rectangle down the bottom and a squarish one up top. Work out the individual areas for these three shapes and then just add them.
For 6 just work out the semicircle, rectangle and triangle areas and add them once more.
Hope that helps! :)
Cut the figure into a rectangle and triangle. You are left with a rectangle with length 6 and width 3, and a triangle with base 15 - 3 = 12 and height 6 + 6 = 12.
A = lw
A = (6)(3)
A = 18 ft^2
So the area of the rectangle is 18 square feet.
A = 1/2bh
A = 1/2(12)(12)
A = 72 ft^2
So the area of the triangle is 72 square feet. Add the two areas together to find the total area of the figure:
18 + 72 = 90 ft^2
So the area of the figure is 90 square feet.

Cut the figure into three rectangles.
4 * 8 = 32
4 * 8 = 32
12 * 12 = 144
32 + 32 + 144 = 208 ft^2
#5
Cut the figure into a rectangle and a triangle.
16 * 8 = 128
1/2 * 6 * 4 = 12
128 + 12 = 140 ft^2
#6
Cut the figure into a square and 4 semi-circles.
3 * 3 = 9
1/2 * 3.14 * 1.5^2 = 3.5325 * 4 = 14.13
9 + 14.13 = 23.13 ft^2
#7
Cut the figure into two rectangles and a triangle.
10 * 8 = 80
4 * 4 = 16
1/2 * 2 * 4 = 4
80 + 16 + 4 = 100 ft^2
#8
Cut the figure into a semi-circle, rectangle, and triangle.
6 * 4 = 24
1/2 * 3 * 2 = 3
1/2 * 3.14 * 2^2 = 6.28
24 + 3 + 6.28 = 33.28 ft^2

A sporting goods store sells right-handed baseball gloves and left handed baseball gloves. In 1 month 12 gloves were sold for a total revenue of $561. Right-handed gloves cost $45 and left-handed gloves cost $52. How many of each type of gloves did they sell?
Answers
12 - x = number of left-handed gloves
45x + 52 (12 - x) = 561
distribute
45x + 624 - 52x = 561
combine like terms
-7x + 624 = 561
subtract 624 from both sides
-7x = -63
divide both sides by -7
x = 9 (amount of right handed gloves)
12 - 9 = 3 (amount of left handed gloves)
They sold 3 left handed gloves and 9 right handed gloves.
To solve this problem, we have to write a system of equations.
Data given;
total number of gloves = 12revenue for 12 gloves = $561right handed gloves (x) = 45left handed gloves (y) = 52Equations[tex]x + y = 12...equation (i)\\ 45x + 52y = 561 equation (ii)[/tex]
From equation (i)
[tex]x + y = 12\\ x = 12 - y...equation (iii)[/tex]
Substitute equation (iii) into equation (ii)
[tex]45x + 52y = 561\\ x = 12 - y\\ 45(12- y) + 52y = 561\\ 540 - 45y +52y = 561\\ 540 + 7y = 561\\ 7y = 21\\ y = 3[/tex]

The linear equation for squirrel y = 12x.
The linear equation for mouse y = 8x
The distance covered by the squirrel is 36km at time 3hours.
The distance covered by the squirrel is 24km at time 3hours.
What is linear equation?A linear equation is an "algebraic equation is of the form y=mx + b where 'm' is the slope of the line and 'b' is the y - intercept".
According to the question,
Animal Mouse Squirrel
Speed(mph) 8 12
"x" the time goes along with x-axis and "y" is the distance covered by the animal.
The mouse time and distance would plot the graph (1,8)(2,16)(3,24)....
The squirrel time and distance would plot the graph (1,12)(2,24)(3,36)....
Let us consider the track is straight line and shorter distance is 50 meters.
Formula for straight line equation y = mx + b where 'b' is the base value, 'x' is the time and 'y' is the distance.
The linear equation for squirrel y = 12x+b and the squirrel starts at 0 meters per hour. so the equation becomes y = 12x.
The linear equation for mouse y = 8x + b and the mouse starts at 0 meters. so the equation becomes y = 8x.
Distance covered by the mouse and the squirrel at time x = 3 we can find the distance covered by mouse and the squirrel.
y =12x
y = 12(3)
y = 36.
The distance covered by the squirrel is 36km at time 3hours.
For mouse, at time x = 3 hours.
y = 8(3)
y=24.
The distance covered by the squirrel is 24km at time 3hours.
Hence, The linear equation for squirrel y = 12x.
The linear equation for mouse y = 8x
The distance covered by the squirrel is 36km at time 3hours.
The distance covered by the squirrel is 24km at time 3hours.

Now that you have converted a terminating decimal number into a fraction, try converting a repeating decimal number into a fraction. Repeating decimal numbers are more difficult to convert into fractions. The first step is to assign the given decimal number to be equal to a variable, . For the decimal number , that means . If , what does 10x equal?
Answers
For the repeating fraction 0.111_1, this would look like
.. x = 0.111_1 . . . . . . . . . . where we use an underscore to identify the following digit(s) as repeating
The next step is to multiply that value by 10 to a power equal to the number of repeating digits. If there is one repeating digit (as here), then you want (10^1)x = 10x.
.. 10x = 1.111_1
The third step is to subtract x from this.
.. 10x -x = 1.111_1 -0.111_1 = 1
.. 9x = 1
And the final step is to divide by the coefficient of x.
.. x = 1/9 . . . . . . this is the value of the repeating decimal fraction.

At silver Gym, membership is $45 per month, and personal training sessions are $25 each. At fit factor, membership is $75 per month, and personal training sessions are $15 each. In one month, how many personal training sessions would Sarah have to buy to make the total cost at the two gyms equal?
Answers
Final answer:
By setting up and solving an equation based on the monthly membership and per-session training costs at both Silver Gym and Fit Factor, it's determined that Sarah would need to buy 3 personal training sessions for the total cost at the two gyms to be equal.
Explanation:
To find how many personal training sessions Sarah would have to buy to make the total cost at Silver Gym and Fit Factor equal, we'll set up an equation. Let x be the number of personal training sessions.
At Silver Gym, the total cost is $45 (membership) + $25x (personal training sessions).
At Fit Factor, the total cost is $75 (membership) + $15x (personal training sessions).
Setting these two expressions equal to each other gives us the equation:
45 + 25x = 75 + 15x.
To solve for x, first subtract 15x from both sides, giving: 10x = 30. Then divide both sides by 10 to isolate x, resulting in x = 3.
Therefore, Sarah would have to buy 3 personal training sessions in one month for the total costs at both gyms to be equal.
Answer:
3 sessions
Step-by-step explanation:
You want to know the number of personal training sessions Sarah would have to buy to make the total costs the same at Silver Gym and Fit Factor. Silver Gym costs $45 per month and $25 per session, while Fit Factor costs $75 per month and $15 per session.
DifferencesSilver Gym costs $25 -15 = $10 more per personal training session, but $75 -45 = $30 less for the monthly fee. This means it takes $30/$10 = 3 sessions for the difference in fees to be made up by the difference in session costs.
Sarah would have to buy 3 sessions for the total cost to be the same.
EquationsIf you need to see this using equations, we can write the cost equations as ...
S = 45 +25x . . . . . . . . cost for x sessions at Silver Gym
F = 75 +15x . . . . . . . . . cost for x sessions at Fit Factor
Setting these equal, we have ...
S = F
45 +25x = 75 +15x
25x -15x = 75 -45 . . . . . . . subtract 45+15x from both sides
10x = 30
x = 30/10 = 3 . . . . sessions for equal cost
Sarah would have to buy 3 sessions for the total cost to be the same.

Additional comment
These "break even" problems usually have a higher fixed cost associated with a lower per use cost, and vice versa. The costs are the same when the number of uses, multiplied by the difference in use cost, comes to the same amount as the difference in fixed costs. Here, the $10 difference in session cost, times 3 sessions, is equal to the $30 difference in monthly membership fee.

If x < 5 and x > c, give a value of c such that there are no solutions to the compound inequality. Explain why there are no solutions
Answers
The solution is the intersection of both solution sets of the given inequalities.
The solutions of the compound inequality must be solutions of both inequalities.
A number cannot be both less than 5 and greater than 5 at the same time.
Final answer:
To ensure there are no solutions to the compound inequality x < 5 and x > c, we can choose c to be 5 or larger, such as c = 6, making the inequality impossible.
Explanation:
To determine a value of c such that the compound inequality x < 5 and x > c has no solutions, we need to choose a value of c that makes the inequality impossible to satisfy.
One way to ensure there are no solutions is to choose c so that it is greater than or equal to 5.
If c is 5 or any number larger than 5, then there is no real number x that can be both greater than c and at the same time less than 5.
For example, if we choose c = 6, then the set of values greater than 6 (x > 6) does not intersect with the set of values less than 5 (x < 5).
Therefore, c = 6 would ensure that there are no solutions to the compound inequality.

In the sophomore class at Dixon high school the number of students taking French is 2/3 of the number taking Spanish. How many students are studying each language if the total number of students in French and Spanish is 310?
Answers
F+S=310
2/3 S + S = 310
(2S + 3S)/3=310
S=[(310)(3)]/5
S=186 students taking Spanish
F=2/3 of 186
F=124 students taking French
To find the number of students studying each language, assign variables, write equations based on the given information, and solve the system of equations.
Explanation:To solve this problem, let's assign variables. Let x represent the number of students taking Spanish, and y represent the number of students taking French.
According to the given information, the number of students taking French is 2/3 of the number taking Spanish. So, we can write this as an equation:
y = (2/3)x
The total number of students taking French and Spanish is 310. So, we can write another equation:
x + y = 310
Now, we can solve these two equations to find the values of x and y. Substituting the value of y from the first equation into the second equation, we get:
x + (2/3)x = 310
(5/3)x = 310
x = (3/5) * 310
x = 186
Substituting x = 186 back into the first equation, we find:
y = (2/3) * 186
y = 124
Therefore, there are 186 students taking Spanish and 124 students taking French.
