Answers

No they 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.

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)

Answers

Subtract 1/2 by F(x) then multiply by 12

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!

Okay, so, input this in your search bar on YT: Understanding integers using temperature

Step-by-step explanation:

And it's been quite a while since I've done integers, but I hope this helps! :)

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.

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.

Answers

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.

Wyatt makes and sells rope doormats. He uses 200 feet of rope for each doormat. He wants to make 25 doormats.

200×25×3

200×25÷3

200÷25×3

200÷25÷3

Answers

200x25(divided)3

That’s because when you find out 200x25 (5000) it will still be in feet and not yards. 1 yard is 3 ft so you would divide your 5000 feet by 3 to change it to yards!
It’s 200x25x3 because he is using 200 feet of rope for each mat and he wants to make 25 of them so that means that is a multiply.Then each yard is 3 feet witch means that it’s multiplying again.

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

Answers

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

you basically do whatever the questions tell you right? if you’re stuck on one just search it up without the “you”
okay so what you do here, mean is when you all all these numbers together and then divide them by the number of numbers here but because they want the difference between these two, you will take whatever you get after you added all them up then divided them by the total amount of number. then you take those two numbers and minus them and that will give you, your answer.
let me work it out for you
56+47+67+77+55+76+85+80+87+69+47+58
=804
divide that by the total numbers you have in the table that is, 12 numbers
so 804 divided by 12 gives you
=67
let me do the next one
52+32+65+63+52+70+72+61+54+43+29+32
=652
then you take that 652 and divide it by the total numbers given in the table which is also 12
so 652 divided by 12
=that’s 54,3
then you take the final answers
67-54,3
and your final answer is 12,7

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.

Answers

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!

which is the measure of ∠DBC?

Answers

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
