4th one false

have fun

Answer:

1st and 3rd are true

2nd and 4th are false

Step-by-step explanation:

Kind note:

I am sure that the triangle you meant was in the image attached. I will find n in the image I attached.

Solution:

We know that:

Step-1: Find ∠C.

Step-2: Find n.

52 and n are a linear pair.

Answer:

y=-2x+3

Step-by-step explanation:

m = slope = y/x = -4/2 = -2

b = y intercept = 3

Answer:

f(x)=-2x-4

Step-by-step explanation:

First of all, I want to say that I'm a 5th grade kid, and I'm studying linear functions in eight grade. The equation is f(x) = mx + b. The b is y intercept. Since the y is -1, we know that f(x)=mx+-1, or f(x)=mx-1. Then, we look that the x. It's 2. Then, substitute 2 for m. F(x) = 2x-1. I'm gonna do the other ones. f(x)=4x-5, f(x) = 6x-9.  We know that the x is substracting 2. The y is subtracting 4. So the rule is f(x) = -2x-4

Step-by-step explanation:

Answer:

area is just multipling the base and the height.

ˆ2 means squared

Step-by-step explanation:

1) 7.6 is the height and 11 the base, so the area would be 83.6cmˆ2

2) there is a triangle but to find the area we divide it into 2 parts. first lets get the measurments settled, we can see that the height is 4ft, and the triangle on the left we can see that the base is the same size as the height, look at the image i attatched if you dont understand how i am explaining it. but we know that the total size of the base is 12, right? well if we subtract the 4 ft from the left triangle we are left that the right triangle has the size of 8ft for base and 4ft for height, if we multiply we have 32ftˆ2 but its a triangle so remember we have to divide this answer by 2, giving us the first area of 16ftˆ2. now we move onto the left triangle, 4 from the height x 4 from the base gives us 16cmˆ2 same as before we divide by two which gives us for the second area 8ftˆ2, now we add both areas we obtained, giving us the area for the whole figure which is, 24ftˆ2

3) for this one we will divide it into 3 parts, look at the image attached, for the steps

4) Ahhh! fractions, dont be nervous these are easy peasy, we know the base is 4in and the height is 3 1/2in. lets convert the fraction into decimals so its easier, so now we have 3.5 as height and 4 as base, we multiplay them which will give us 14inˆ2 since its a triangle we have to divide by 2! our answer will be 7inˆ2

For 5 and 6 look at the image :]

Answer:

In order from largest to smallest:

quart, pint, cup

Step-by-step explanation:

A quart is the same thing as 4 cups or 2 pints. If we still need more liquid we can switch to using gallons. However, a gallon is the same as 16 cups or 8 pints or 4 quarts.

Answer:

Variability

Step-by-step explanation:

Mean absolute deviation (MAD) of a data set is the average distance between each data value and the mean. Mean absolute deviation is a way to describe variation in a data set. Mean absolute deviation helps us get a sense of how "spread out" the values in a data set are.

Answer:

y = 2Kx -5

Step-by-step explanation:

make karen's coins=x and Kevin's coins=y

the information given tells us that Kevin has 5 less coins than double Karen's. This means that to find Kevin's amount of coins, you must double Karen's coins (2x) and then subtract 5 (-5). Hope this helps!

y = 2x -5

I'm sorry if it is wrong... This is how i understood the problem

Answer:

Angles 8 and 2 are alternate exterior angles, meaning they are on the same side of the transversal that runs through it but are on the outside.

Alternate exterior angles are supplementary, which means they both have a sum of 180°.

So if you were to find the supplement of 60°, it would be 120°.

This is because;

x + 60 = 180

-60        -60

x = 120, so ∠2 = 120°

Answer:

B

Step-by-step explanation:

Answer: B: Unlikely.

Step-by-step explanation: Lower probabilities have less of a likelihood when it comes to an event like this.  1/8 is a pretty low probability, so, therefore, it isn't likely that landing yellow on a spinner would happen at all.  

Let me know if this is right! :)

Answer:

the greatest common factor is 3

Answer:

3

Step-by-step explanation:

it’s because 3 can go into 12 and 27 and it’s the highest! Hope this help :)

Answer:

1. 13
2. 3.14 (estimation: 3)

3. 14

Step-by-step explanation:

  So, if each square represents 1 square inch, then you know that the big square equals 5x5 square inches, or 25 square inches. So, for the first problem, you can subtract 25 by 12, because we know that the white squares sum to 12. For question 2, the formula to find the area of a circle is pie*radius^2, so we get 3.14*1^2, which is 3.14. For number 3, we can simply count the shaded squares, and you get 14.

Answer:

D. (x, y) --> (2/5x, 2/5y)

Step-by-step explanation:

if you multiply each coordinate on the outer ellipse B by 2/5, you get the coordinates for the inner ellipse A.

For example, if you multiply each unit in coordinate (5,0) on ellipse B by 2/5 you would get:

5*2/5 = 2

0*2/5 = 0

= (2,0)

Answer: 18 quarters

Step-by-step explanation:

second pile = x

first pile = x - 5

third pile = x - 4

fourth pile = 3x  

total amount of quaters = 27

x + x - 5 + x - 4 + 3x = 27  

6x = 36 x = 6        

fourth pile = 3(6) = 18

Solution:

Note that:

This means that...

First, let's find the number of quarters in 2nd pile.

Open the brackets.

Combine like terms.

Simplify the RHS.

Add 9 both sides.

Divide 6 both sides.

Now, substitute the number of quarters in 2nd pile in it's equation.

Answer:

169,611

Step-by-step explanation:

x = total number of registered doctors

28.3/100 = 0.283

0.283x = 48,000

/0.283      /0.283

x = 169611.307

x = 169,611 (to the nearest whole number)

Therefore, our final answer is 169,611.

Hope this helps!
