Answer:
125˚
Step-by-step explanation:
The angles given are supplementary. So we can set up the equation :
(3x+5)+(x+15)=180
Then we can solve for x.
Combine like terms:
4x+20=180
4x+20-20=180-20
4x=160
4x/4=160/4
x=40
Now we plug in 40 for x.
3(40)+5=<A
120+5=<A
<A=125

Select the correct solution for the expression. 2/5 + 3/8 A. 2/5 + 3/8 = 5/13 B. 16/40 + 15/40 = 31/40 C. 10/40 + 24/40 = 34/40 D. 2/5 + 3/8 = 6/40
Answers
Answer:
B
Step-by-step explanation:
To add 2/5 and 3/8, we need to find a common denominator for the two fractions.
The smallest multiple of 5 and 8 is 40, so we can use 40 as the common denominator.
Multiplying the numerator and denominator of 2/5 by 8, we get:
2/5 = 16/40
Multiplying the numerator and denominator of 3/8 by 5, we get:
3/8 = 15/40
Now, we can add the two fractions:
2/5 + 3/8 = 16/40 + 15/40
Simplifying the numerator, we get:
2/5 + 3/8 = 31/40
Therefore, 2/5 + 3/8 is equal to 31/40.

Describe what happens to the Car as it moves from BLUE to B"L"U"E".
Answers
Answer: As the car moves from "BLUE" to "B"L"U"E", it slows down its acceleration, reaches its maximum velocity, and then decelerates. The change in the car's motion is due to the change in the slope of the graph from positive to zero to negative. At "BLUE", the car has the highest positive slope, which represents the maximum acceleration. As the car moves towards "B"L"U"E", the slope of the graph decreases and becomes zero at the highest point of the graph. At this point, the car has reached its maximum velocity, and it starts to decelerate towards "B"L"U"E". Finally, at "B"L"U"E", the slope of the graph is negative, indicating that the car is decelerating.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total length of the locomotive train be = A
Now , the equation is given as
The ratio of locomotive train model is = 1 : 87.1
So , 1 inch of the locomotive train model = 87.1 inch of the the original train
Now , the total length of the model of locomotive train in inches = 10.4712
So , substituting the values in the equation , we get
Total length of the locomotive train in inches = total length of the model of locomotive train in inches x 87.1
Total length of the locomotive train in inches = 10.4712 x 87.1
Total length of the locomotive train in inches = 912.04152 inches
Now , 1 inch = 0.0833333 feet
So , 912.04152 inches = 0.083333 x 912.04152 feet
Therefore, the value of 912.04152 inches = 76.00346 feet
Hence , The total length of the locomotive model train in feet is 76 feet

Using a directrix of y = −2 and a focus of (2, 6), what quadratic function is created?
here are the answers given
\/
f(x) = −one eighth (x − 2)2 − 2
f(x) = one sixteenth (x − 2)2 + 2
f(x) = one eighth (x − 2)2 − 2
f(x) = −one sixteenth (x + 2)2 − 2
Answers
Answer:
f(x)=1/16(x-2)^2+2
Step-by-step explanation:
The Equation can be written like this:
f(x) = 1/(4p)(x -h)^2 +(k-p)
where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...
f(x) = 1/16(x -2)^2 +2

1. Area is 1800 cm. I found this out by multiplying 36 and 50 together.
2. He can figure out that the scale factor 5:1 means that 1 cm in the drawing is 0.2 cm in reality, so he would take 36 and 50 and multiply them both by 0.2 cm then add them to get 17.2, which is the actual area of the rectangle.
3. Actual area is 17.2

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

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.
Answers
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.

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answers
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.

Step-by-step explanation: 5 cups x 4 = 20 cups. Do the same to the other side. 2 batches x 4 = 8 batches
Answer:
She can make 8 batches of cookies.
Step-by-step explanation:
5 cups of flour equals 2 batches. 10 cups of flour equals 4 batches. 15 cups of flour equal 6 batches. Finally, 20 cups of flours equals 8 batches. You would keep adding 2 batches for every 5 cups of flour you have.
