Answer:
39.8 =x
Step-by-step explanation:
Since this is a right triangle we can use trig functions
cos theta = adj / hyp
cos 34 = x / 48
Multiply each side by 48
48 cos 34 = x
39.79380348 =x
To the nearest tenth
39.8 =x

Deanna borrowed $650 at 8% 0 simple interest. How much - 52 interest did she pay for 1 year?
Answer:
i = ($650)(0.08)(1) = $52
Step-by-step explanation:
The formula for simple interest is i = prt. Here p = $650, r = 0.08 and t = 1 (year). Then the simple interest Deanna paid for this one year loan was
i = ($650)(0.08)(1) = $52

A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot plots below show the results. Students A dot plot titled Students. A number line going from 0 to 9 labeled number of siblings. There are 2 dots above 0, 4 above 1, 7 above 2, 5 above 3, 2 above 4, and 0 above 5, 6, 7, 8, and 9. Teachers A dot plot titled Teachers. A number line going from 0 to 9 labeled Number of siblings. There is 1 dot above 0, 3 dots above 1, 2 above 2, 4 above 3, 5 above 4, 3 above 5, 1 above 6, 0 above 7, 1 above 8, and 0 above 9. When comparing the shape of the two sets of data, what conclusion can someone draw? The students tend to have fewer siblings than the teachers. The teachers tend to have fewer siblings than the students. Both the students and the teachers have a wide range of siblings. Both sets of data have the same shape. the answer is- a. The students tend to have fewer siblings than the teachers.
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.
Answer:
The sum is A

A bag contained 18 red marbles, 14 green marbles, and 20 blue marbles. A marble was randomly pulled, the color recorded, and then put back into the bag. This table above shows the results after 25 pulls.
What was the relative frequency of selecting a red or blue marble?
Red:8
Blue8
Green9
Number of red marbles pulled = 8
Number of blue marbles pulled = 8
Total marbles pulled = 25
Relative Frequency = Total Frequency / Total number of data values
Relative Frequency of red marble = 8/25
= 32%
Relative Frequency of blue marble = 8/25
= 32%

Option d. m>7 is the correct answer.
Given,
2m+5>19
or, 2m+5+(-5)>19+(-5) [adding both side with a negative number doesn't
change the inequality sign]
or, 2m>14
or, (2m/2)>(14/2) [also dividing both sides by a non-negative number doesn't change the inequality sign]

Dan is cutting 4.75-foot lengths of twine from a 249-foot spool of twine. He needs to cut 42 lengths and says that 40.5 feet of twine will remain. Show that this is reasonable.
To show that Dan's statement is reasonable, we can set up an equation to represent the situation. Let's let x represent the number of feet of twine that Dan has cut.
We can then set up the following equation: \(4.75x = 249 - 40.5\)
Solving for x, we find that x = 42. This means that Dan has cut 42 lengths of twine, which is what he said he would do.
Since the number of lengths of twine that Dan has cut and the amount of twine that will remain match what Dan said, his statement is reasonable.

A theater company has raised $810.75 by selling 15 floor seat tickets. Each ticket costs the same.
Part A: Write an equation with a variable that can be solved to correctly find the price of each ticket. Explain how you created this equation. (5 points)
Part B: Solve your equation in Part A to find the price of each floor seat ticket. How do you know your solution is correct? (5 points)
Part A: 15x= $810.75. Part B: x= $54.05
The total money earned from 15 tickets is $810.75.
Assume, the money earned from selling 1 ticket is $x.
Therefore, the money earned from selling 15 tickets= 15*x= 15x= $810.75
Here, the variable, i.e. the changing value, is x which is the price of each ticket. The equation hence derived is 15x= $810.75.
Using the equation above,
15x= $810.75.
Dividing both sides by 15,
We get,
x= $54.05
Hence, $54.05 is the price of each ticket.

All the dimensions of a cuboid are whole numbers, and its volume is 24 units^3. Which one of the following could NOT be one of its dimensions?
A.) 3
B.) 4
C.) 5
D.) 6
First Person who gets it right and EXPLAINS will get branliest! :-)
5 is the answer.
Review:What is a cuboid?
A cuboid is a rectangle, but in 3D form.
Do we calculate area or volume in a cuboid?
We calculate the volume for 3D shapes. For 2D shapes, area is used.
If/Then:
Now, if the volume of the cuboid is 24 units³ then:
x × x × y
Now, lets fit all our options to see which one is NOT the dimensions.
Option A:
x × x × 3 = 24 units³
x × x = 12 units³ ✔
This is possible.
Option B:
x × x × 4 = 24 units³
=> x × x = 6 units³ ✔
This is possible.
Option C:
x × x × 5 = 24 units³
=> x × x = 24/5 units³ ❌
This is not possible. This will be our answer.
Option D:
x × x × 6 = 24 units³
=> x × x = 4 units³✔
This is possible.
Conclusion:
So after working on our problem, we can conclude that C is our answer. Hoped this helped.
Find x and y. pls help
Answer:
y = 21
x = 8
Step-by-step explanation:
AB = 180
27 + 3y = 90°

-----------------------
3y = 63
÷3 ÷3
--------------
y = 21
x + 27 + 3y + 8x + 18 = 180
9x + 45 + 3(21) = 180
9x + 45 + 63 = 180
9x + 108 = 180
-108 -108

An experiment involves rolling two dice simultaneously. The following table shows the possible outcomes using the format of (die 1,die 2).
What is the probability of rolling 2 even numbers?
To determine the probability of rolling two even numbers, we need to find the favorable outcomes (outcomes with two even numbers) and divide it by the total number of possible outcomes.
The possible outcomes when rolling two dice are:
(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)
(2,1), (2,2), (2,3), (2,4), (2,5), (2,6)
(3,1), (3,2), (3,3), (3,4), (3,5), (3,6)
(4,1), (4,2), (4,3), (4,4), (4,5), (4,6)
(5,1), (5,2), (5,3), (5,4), (5,5), (5,6)
(6,1), (6,2), (6,3), (6,4), (6,5), (6,6)
Out of these, the favorable outcomes (outcomes with two even numbers) are:
(2,2), (2,4), (2,6), (4,2), (4,4), (4,6), (6,2), (6,4), (6,6)
Thus, there are 9 favorable outcomes.
The total number of possible outcomes is 36 (since each die has 6 possible outcomes).
Therefore, the probability of rolling 2 even numbers is:
\(\text{Probability} = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Possible Outcomes}} = \frac{9}{36} = \frac{1}{4} = 0.25\)
Hence, the probability of rolling 2 even numbers is 0.25 or 1/4.
