Theo budgets $154 for karate classes. He buys a karate uniform, called a dogi, for $12. If it costs $8 to attend each karate class, which inequality below represents the number of classes. c, that Theo can take?
Answers
Final answer:
The inequality representing the number of karate classes Theo can take is c ≤ 17, considering his budget after buying a dogi and the cost per class.
Explanation:
The question asks us to find the inequality that represents the number of karate classes, c, Theo can take given his budget scenario. Theo budgets $154 for his karate classes and spends $12 on a dogi. This leaves Theo with $154 - $12 = $142 for classes. Since each class costs $8, we divide the remaining budget by the cost per class to find the maximum number of classes he can take:
$142 ÷ $8 = 17.75.
Since Theo cannot attend a fraction of a class, we round down to 17. The inequality representing the number of classes Theo can take would be c ≤ 17, where c is the number of classes Theo can attend.
The inequality that represents the number of classes, [tex]\( c \)[/tex], that Theo can take is:
[tex]\[ 8c + 12 \leq 154 \][/tex]
To derive this inequality, we start by considering the total amount Theo has budgeted for karate classes, which is $154. From this budget, Theo has already spent $12 on purchasing a karate uniform. Therefore, the remaining amount available for attending the classes is [tex]\( 154 - 12 \)[/tex].
Now, each karate class costs $8, so the total cost for attending [tex]\( c \)[/tex] classes is [tex]\( 8c \)[/tex]. To ensure that Theo does not exceed his budget, the total cost including the uniform should be less than or equal to $154.
Hence, the inequality that represents this situation is:
[tex]\[ 8c + 12 \leq 154 \][/tex]
This inequality states that the cost of the uniform plus the cost of the classes must be less than or equal to Theo's budget. Solving for [tex]\( c \)[/tex] will give us the maximum number of classes Theo can attend without exceeding his budget.

[tex]Average=\frac{45+50+50+55+60+60+70+75+80+85+90+90+95+100+100+105+110+110+115+120+120}{21}[/tex]
[tex]Average=\frac{1785}{21}[/tex]
[tex]Average=85[/tex]
From the given dot plot it is clear that number of dots for group S is 17 and the time taken by the students of groups S are
50, 55, 60, 60, 65, 70, 70, 80, 90, 90, 95, 100, 105, 110, 110, 115, 120
[tex]Average=\frac{50+55+60+60+65+70+70+80+90+90+95+100+105+110+110+115+120}{17}[/tex]
[tex]Average=\frac{1445}{17}[/tex]
[tex]Average=85[/tex]
The average time of both groups are same.
Since both groups show about the same average time, therefore the correct option is C.

Answers
Answer:
16 cm
Step-by-step explanation:
Given : The area of triangle ABC is 24 square centimeters.
To Find: If B = 30° and a = 6 cm, what is the measure of side c?
Solution:
Formula : [tex]Area = \frac{1}{2} \times a \times c \times sin B[/tex]
a = 6
Area = 24
B = 30°
Substitute the values in the formula
[tex]24 = \frac{1}{2} \times 6 \times c \times sin 30[/tex]
[tex]24 = \frac{1}{2} \times 6 \times c \times \frac{1}{2}[/tex]
[tex]24 =3 \times c \times \frac{1}{2}[/tex]
[tex]\frac{24 \times 2}{3} =c[/tex]
[tex]16=c[/tex]
Hence the measure of side c is 16 cm
So, Option c is correct.

1) If all angles in one triangle are equal to the angles in another one, then the 2 are equal.
2) If the sides have the same proportions, then the 2 triangles are similar.
1) We have that all the angles of the 2 triangles have an equal angle in the other triangle. In specific, Q is matched to B, P to A and R to C. Hence, since corresponding angles are congruent, the two triangles are similar.
2) Here we are given information about the sides of the triangles, so we will check the second criterion. We form the ratio of the largest sides of each trangle and the shortest sides. 30/5=6. For the shortest sides, 18/3=6. Finally for the middle sides, 24/4=6. Hence, we have that the triangles are similar since the ratios are equal. (it doesn't matter whether we take the bigger or the smaller side as a numerator, as long as we are consistent).

A weight attached to a spring is at its lowest point, 9 inches below equilibrium, at time t = 0 seconds. When the weight it released, it oscillates and returns to its original position at t = 3 seconds. Which of the following equations models the distance, d, of the weight from its equilibrium after t seconds?
a. d=-9cos(pi/3)t
b. d=-9cos(2pi/3)t
c. d=-3cos(pi/9)t
d. d=-3cos(2pi/9)t
Answers
For a better understanding of the explanation provided here kindly go through the file attached.
Since, the weight attached is already at the lowest point at time, t=0, therefore, the equation will have a -9 as it's "amplitude" and it will be a Cosine function. This is because in cosine function, the function has the value of the amplitude at t=0.
Now, we know that the total angle in radians covered by a cosine in a given period is [tex] 2\pi [/tex] and the period given in the question is t=3 seconds. Therefore, the angular velocity, [tex] \omega [/tex] of the mentioned system will be:
[tex] \omega=\frac{2\pi}{3} [/tex]
Combining all the above information, we see that the equation which models the distance, d, of the weight from its equilibrium after t seconds will be:
[tex] d=-9cos(\frac{2\pi}{3})t [/tex]
Thus, Option B is the correct option. The attached diagram is the graph of the option B and we can see clearly that at t=3, the weight indeed returns to it's original position.
Answer: B.

Find the number of real number solutions for the equation. x^2 + 5x + 7 = 0 0 cannot be determined 1 2
Answers
Answer:
No real solutions, or 0
Explanation:
We can determine how many real solutions a quadratic function has, we can use the quadratic formula.
The quadratic formula for expressions written in ax² + bx + c form is:
[tex]x = \frac{-b +/- \sqrt{b^{2}-4ac}}{2a}[/tex]
In the equation x² + 5x + 7, a = 1, b = 5 and c = 7
When we plug them in, we get:
[tex]x = \frac{-5 +/-\sqrt{5^2 - 4(1)(7)}}{2(1)}\\ \\= \frac{-5+/-\sqrt{25 - 28}}{2}\\ \\=\frac{-5+/-\sqrt{-3}}{2}}[/tex]
We cannot find the square root of a negative number without diving into the realm of imaginary numbers in which √-3 becomes i√3. Therefore, the equation has no real solutions. This is because the equation x² + 5x + 7 is an upward-facing parabola translated up 7 units and, as such, does not cross the x-axis. If the equation yields a graph that does not cross the x-axis, then there will be zero answers for what variable x equals.

a club has 15 members. How many ways can the club choose a president, vice president, and treasurer? (club rules forbid one person from holding more than one office.) show all work
Answers
There are 2730 different ways for a club with 15 members to choose a president, vice president, and treasurer, with each office being held by a different person.
Explanation:To determine the number of ways the club can choose a president, vice president, and treasurer, we can use the concept of permutations since the order of selection matters here, and no person can hold more than one office.
The first office to be filled is the president's.
There are 15 potential members to fill this role.
Once the president has been chosen, there are 14 remaining members who could be the vice president.
Finally, for the treasurer, there are 13 members left to choose from.
To find the total number of ways to choose these officers, we multiply the number of choices for each office together.
Number of ways = 15 (for president) × 14 (for vice president) × 13 (for treasurer) = 2730 ways.
So, there are 2730 different ways in which the club can select a president, vice president, and treasurer.

Aaron bought a large basket of 59 apples for $22.95. He also bought a small basket of 18 apples for $8.95. Which am amount is the closest estimate of the cost per apple?
Answers
1) Aaron bought a large basket of 59 apples for $22.95
2) He also bought a small basket of 18 apples for $8.95.
so
total cost=$22.95+$8.95.=$31.9
total apples=59+18=77 apples
[closest estimate of the cost per apple]=total cost/total apples
[closest estimate of the cost per apple]=31.9/77-----> $0.41 per apple
the answer is
$0.41 per apple
Calculate the cost per apple for large and small baskets, $0.39 per apple is the closest estimate.
To estimate the cost per apple, one must calculate the price of each apple in the large and small baskets, then average these amounts, resulting in approximately 44 cents per apple.
To find the cost per apple:
Calculate the cost per apple in the large basket: $22.95 / 59 apples = $0.39 per apple.
Calculate the cost per apple in the small basket: $8.95 / 18 apples = $0.50 per apple.
Compare the two costs: $0.39 is the closest estimate of the cost per apple.
