which is the measure of ∠DBC?
Answer: 20°
Step-by-step explanation:
There is 180 degrees in the triangle. ∠C is 50°, ∠A is 80°, ∠B is 30°, and the total adds up to 160°, so 180-160 equals 20.
Answer: 20 degrees
Step-by-step explanation: if you add up the angles of any triangle, the sum should always be 180. so add up angle A and angle C :
80 + 50 = 130
subtract that from 180 to find out what angle ABC is:
180 - 130 = 50
since we know that angle ABD is 30 degrees, all we have to do now is subtract that from 50:
50 - 30 = 20
angle DBC = 20 degrees
Jenny has some tiles in a bag. The tiles are of three different colours: purple, pink, and orange. Jenny randomly pulls a tile out of the bag, records the colour, and replaces the tile in the bag. She does this 50 times. The results are recorded in the given table:
Colour of Tile Purple Pink Orange
Number of times the tile is drawn 6 18 26
What is the experimental probability that Jenny will pull out a pink tile?
fraction 32 over 50
fraction 18 over 50
fraction 18 over 32
fraction 26 over 32
Answer:

Step-by-step explanation:
Answer:
fraction 18 over 50
Step-by-step explanation:
Jenny pulled out 50 in total and 18 of them are pink.
So fraction 18/50, 18 over 50.

A traveler takes a taxi from the airport to a hotel. The taxi driver charges $1.90 initial charge plus $1.25 per mile. Which equation can be used to find y, the total cost of the trip, if x represents the number of miles of the trip?
$1.90 + $1.25 x X = Y?
hope this helps I'm not sure
Step-by-step explanation:
This is a linear function with initial value $1.90 and slope $1.25/mile:
total cost = $1,90 + ($1.25/mi)x
40 cm = how many m ?
Answer: .4m
Step-by-step explanation:
move decimal over
Answer:
⅖ m or 0.4 m
Step-by-step explanation:
1 m [meter(s)] = 100 cm [centimeter(s)].
_____________________________
(x) m = (100)(x) cm
(100)(x) = 40
x = 40 / 100
x = 4 / 10 = 2 / 5
x = 0.4
A triangular prism is 31 yards long and has a triangular face with a base of 36 yards and a height of 24 yards. The other two sides of the triangle are each 30 yards. What is the surface area of the triangular prism?
Determine whether these two triangles are similar, and if so what is the ratio of their sides?
Yes, ratio = 3/4
Yes, ratio = 3/8
Yes, ratio = 4/5
No, these triangles are not similar
Answer:
No, these triangles are not similar.
Step-by-step explanation:
If they were similar by ratio you would be able to divide 3/8 and 4/10 and get the same decimal but instead you get 0.375 for 3/8 and 0.4 for 4/10.

Answer:
-50 degrees F
Step-by-step explanation:
Zero is the point on the number line where numbers to the left of zero are negative, and numbers to the right are positive. 50 degrees below zero = 50 degrees less than zero, so -50 degrees.

a little bigger than 73°. How ever, not quite a right angle (90°)
the function F is defined by F(x) 12/x+1/2. use this formula to find the following values of the function. F(a/2)
Answer:
F([tex]\frac{a}{2}[/tex]) = [tex]\frac{24}{a} +\frac{1}{2}\\[/tex]
Step-by-step explanation:
so basically what you want to do is insert the f(x) value into the equation. What I mean by that is in this equation, since f(x) = f(a/2), you want to substitute A/2 into the equation, so you'll have [tex]\frac{12}{\frac{a}{2} }[/tex], if you can't see that, its 12/a/2. In other words, this is 12 ÷ [tex]\frac{a}{2}[/tex] , which you can also format as 12 ·[tex]\frac{2}{a}[/tex], because of the "keep, change, flip" thing. Well, you know that equation is equal to 24/a so you just have to add back the 1/2, and you have your answer!
Side Note:
I know the format is terrible, but the answer is right so please bear with me :)I know the person asking this question asked it a year ago so i'm just answering it for future usersIf i'm guessing correctly, this question originated from RSM, and I found it googling rsm problems, and my answer is correct in RSM, so if you have this same question on your RSM homework, I promise you it's rightIf you got this from RSM homework, and you have other questions about the same types, like 7abcdegi, comment, because I have those answers tooIf you have any questions about this answer, also comment, I would love to helpIf the user who asked this question is still active, I would really appreciate brainliest if you think this deserves itHope this helps!! If it did, please give it a good rating so others know they can trust it!P.S i know the commenting feature is funky but if u ever have any other questions shoot me a friend request so i'll know when you post stuff :)
A basketball game a team made 52 successful shots they were a combination of 1- and 2- point shots the team scored 86 points in all write and solve a system of equations to find the number of each type of shot
Answer: 15
Step-by-step explanation:
x = one point shots
y = two point shots
1) Setup your equations.
x + y = 52
x + 2y = 89
2) Isolate a variable.
x = 52-y
3) Plug in.
(52-y) + 2y = 89
52 +y =89
y=37
4) Solve for x.
x = 52 -37
x=15
5) Check your answer.
15 + 2(37) = 89
15+74=89
89=89
37+15 = 52
52=52
x = one point shots
y = two point shots
1) Setup your equations.
x + y = 52
x + 2y = 89
2) Isolate a variable.
x = 52-y
3) Plug in.
(52-y) + 2y = 89
52 +y =89
y=37
4) Solve for x.
x = 52 -37
x=15
5) Check your answer.
15 + 2(37) = 89
15+74=89
89=89
37+15 = 52
52=52

Charlotte recorded the number of minutes she spent exercising in the past ten days: 9, 13, 5, 2, 9, 1, 14, 3, 5, 7. Find the median of the data.
Answer:
The median is 7.
Step-by-step explanation:
In order to find the median, you need to ut the numbers in either least to greatest form, or greatest to least (FIRST).
I'm gonna do both as an example.
Greatest to least:
14, 13, 9, 9, 7, 5, 3, 2, 1
Least to greatest:
1, 2, 3, 5, 7, 9, 9, 13, 14
It is REALLY important that you use ALL of the numbers you are given, even if there are two or more of the same number.
The next thing you need to do is find the number that is in the middle.
It will be the same for both least to greatest AND greatest to least.
You can either count one from either side, going in a pattern, OR you can count how many there is, divide it by 2, and whatever answer you get, count that many times over from one side.
In this case, your answer goes like this:
since there are 9 numbers, and 9 is not an even number, you will have only one median. Having 2 medians IS normal and it IS ok.
In this case, you want to go down one number (from 9) and divide that. So you do 8 divided by 2, which is 4. Count that many times over and you have your answer, 7.
I hope this helped you!
Have a great dayyyy

what is the peremiter of DEFG
Answer:
The answer is 22 units
Step-by-step explanation:
To find the perimeter we have to add all sides units. So, it length is 7 units and breadth is 4 units, so 7+7=14 and 4+4=8 , and then we will add the l and b , so 14+8=22

Andre is making paper cranes to decorate for a party. He plans to make one large paper
crane for a centerpiece and several smaller paper cranes to put around the table. It takes
Andre 10 minutes to make the centerpiece and 3 minutes to make each small crane. He will
only have 30 minutes to make the paper cranes once he gets home.
1. Andre wrote the inequality to plan his time. Describe what , , 10,
and 30 represent in this inequality.
2. Solve Andre’s inequality and explain what the solution means.
Answer:
10 + 3x </= 30
x </= 6.666
He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.
Step-by-step explanation:
10 + 3x </= 30
10 is the minutes for the centerpiece
3 is the minutes to make each small crane
x is the number of small cranes he can make
he has less than or equal to 30 minutes to complete them.
10 + 3x </= 30
subtract 10 from both sides
3x </= 20
x </= 6.666
He can make at most 6 cranes before his time runs out. He would be 2/3 through the next small one when time runs out.
