2. What is the area of each cut surface

3. What is the total area janey still needs to paint? Explain how you found your answer

Answer:

4

Step-by-step explanation:

Answer:

x = 17

Step-by-step explanation:

Nice set up. It's very clear.

Multiply both sides by 3

3(x-2)

===== = 5 *3

  3

Cancel the 3 on the left. Combine the right.

x - 2 = 15

Add 2

x - 2 + 2 = 15 + 2

x = 17

==============

(17 - 2) / 3

15/3

5  

The right hand side is also 5

Answer:

you want to put your first pint at negative 3 on the Y axis. and then you want to go down 2 and right 1 to crest your slope.

Answer:

The answer is 10

Step-by-step explanation:

The longer leg of this triangle is √3 times longer than the shorter leg. Since the longer leg is 5√3, then the shorter leg will be 5. The hypotenuse is twice the size of the shorter leg, so 5*2 is 10.

Answer:

Ricky

Step-by-step explanation:

24 divided by 3 equals 8 drawings per minute

28 divided by 4 equals 7 drawings per minute

Answer:

Ricky

Step-by-step explanation:

One way to solve this is finding out how many characters they draw per minute. In order to find this, you must divide the amount of cartoon characters by the time. For example, 24 divided by 3 is 8 and 28 divided by 4 is 7. Ricky draws 8 per min and Leo draws 7 per min. Therefore, Ricky draws at a faster rate. Hope this helps! :)

Answer:

Step-by-step explanation:

Let  

V

be the number of vertices of a polyhedron,  

F

the number of faces of that polyhedron, and  

E

be the number of edges. The quantity  

χ

=

V

−

E

+

F

is called the Euler characteristic (of a polyhedron). In the case of convex polyhedra,  

χ

=

2

.

Consider, for example, a tetrahedron (which is the simplest solid). It has 4 faces,  

1

(

=

edges, and

=

vertices. Thus we have

F

=

.

Euler's formula holds for all Platonic solids (tetrahedron, cube, octahedron, dodecahedron, and icosahedron). Since a cube and an octahedron are dual polyhedra (each is formed by connecting the centers of the faces of the other), their  

V

and  

F

values are equal to the  

F

V

values of the other. (The same is true for the dodecahedron and icosahedron).

answer:

Both sequences are geometric

Step-by-step explanation:

because both have common differences of 2 times

Answer:

4.1, 8.2, 16.4, 32.8,... is a geometric sequence.

Step-by-step explanation:

Given the first sequence

18, 36, 54, 72,...

we know that the geometric sequence is the sequence that has the same common ratio 'r' (constant ratio).

Computing the ratios of all the adjacent terms:

[tex]\frac{36}{18}=2,\:\quad \frac{54}{36}=1.5,\:\quad \frac{72}{54}=1.33333\dots[/tex]

As the ratio is not constant.

Hence, 18, 36, 54, 72,... is NOT the geometric sequence.

Given the second sequence

4.1, 8.2, 16.4, 32.8,...

we know that the geometric sequence is the sequence that has the same common ratio 'r' (constant ratio).

Computing the ratios of all the adjacent terms:

[tex]\frac{8.2}{4.1}=2,\:\quad \frac{16.4}{8.2}=2,\:\quad \frac{32.8}{16.4}=2[/tex]

As the ratio of all the adjacent terms is the same (constant ratio).

Hence, 4.1, 8.2, 16.4, 32.8,... is a geometric sequence.

Therefore, 4.1, 8.2, 16.4, 32.8,... is a geometric sequence.

Answer:

no thanks

Step-by-step explanation:

i don't wanna help u nerd

Answer:

potato

yes potato

Answer:

So, in order to solve this, you need to know slope. Slope is equal to rise (up/down) over run (left/right). The number at the end, which in this case is 2, is the y-intercept. So, first, graph a point on the y-axis, which is 2. Next, you can place any other point on the line, as long as it follows your slope, which is 3/5. If you need a better explanation, just graph (0, 2) on the y-axis and also graph the point (3, 5).

Have a good one,

Step 2: Solve

Answer:

The temperature would have dropped 15 degrees so it would have been colder

Step-by-step explanation:

The values are missing in the question. They are : 16.3,12.8,13,32.2,28.1,34.4,46.4,53,15.4,18.2

16.3,12.8,13,32.2,28.1,34.4,46.4,53,15.4,18.2

We calculate sample mean and std deviation from given data.

Sample Mean,    =269.8/10=26.98

Sample Variance,     =1859.496/9=206.610667

Sample std dev,s==√206.610667≈14.373958

We want to test two tailed hypothesis:

: σ=12

: σ≠12

Given: s=14.373958⇒  =206.610667,n=10

Significance level, a=0.1 Degrees of freedom, df=n-1=9

Since this is two tailed test, we need area of α=0.1 on either side of critical value. This means area of 0.05 on right of positive critical value.

Critical values are given by   with 9 degrees of freedom.

We can use chi-square table or following excel commands:

CHISQ. INV(0.95,9)=3.32511284307

CHISQ. INV (0.05,9)=16.9189776046

Critical Values, =3.325  and =16.919

Since this is two tailed test, the decision rule or rejection criteria is:

Reject null hypothesis if test statistic is less than or equal to left critical value OR more than or equal to right critical value, i.e,

Reject    if ≤3.325  OR ≥16.919

Test statistic is given by  =((9)*206.610667)/144=12.913167    

Test statistic, =12.913

since test statistic is between two critical values, we (do not reject ) (i.e, we fail to reject .

Conclusion: There is (not sufficient) evidence to conclude that standard deviation is not equal to 12 .

Alternatively, we can use p-value approach. The decision rule or rejection criteria is: reject null hypothesis if p-value is less than or equal to significance level (α), i.e, reject  if p-value ≤0.1

P-value is twice the (smaller) tail area of test statistic because this is two tailed test. We can use excel function to find this. 2*M IN (CHISQ.DIST (12.913167,9,  TRUE ) 1-CHISQ.DIST 12.913167,9,  TRUE ) =0.333149809868

P-value =0.3331

since p-value is greater than significance level (α),we (do not reject ) (i.e, we fail to reject ).

Conclusion: There is (not sufficient) evidence to conclude that standard deviation is different from 12 .

Answer:

12 white cars

Step-by-step explanation:

Our ratio is 4:3

16:?

We can determine white cars by dividing 16/4 to find how many more cars we have than our original ratio.

16/4 = 4

3 x 4 = 12

16:12 = 4:3

Answer:

Step-by-step explanation:

They're both ways of expressing the equation of a line. Depending on the information you're given, it's easier to use one or the other. Like if you're given the slope and y intercept, it might be easier to use slope intercept equation. If you're given 2 points on a line, it might be easier to calculate the slope between them and then use the pointslope equation using one of the two points given to find the euqation of the line. Let me know if there's more I need to clarify

Answer: The slope would be 2/5.

Step-by-step explanation: To find the slope, it's rise divided by run. The 2 points on this graph are (-2,-1) and (3,1). So basically,  change in y value, divided by the change in x value.

Answer:look at the angle bro and you got the angle just look at it good enough

Answer: Hey! no need to fret ok so your trying to find what multiplied by itself would get 1109. Make an algebra equation and solve for x:

x • x = 1109

x ≈ 33.302

-0.9 -0.4. Make sense at all???

Answer: I think the answer is 4 because usually when you find the rate of something it means you divided the two numbers or however many numbers you have... So, 12 divided by 3 is 4...  So, 4 hours for each lawn she mows... or something like that... So, 4 lawns per hour...

Final answer is 4 lawns per hour... If this isn't the correct answer i am very sorry... Stay safe and have a great weekend!!! :D

Answer:

4 lawns per hour

Step-by-step explanation:

4 lawns per hour or 1  lawn per 15 mins.

12/3 is the unit rate so 4/1.

Hope this helps plz hit the crown :D
