By proportion that is:(54/150) * 8450= 54 * 56 1/3= 3042

Answer:

By proportion that is:(54/150) * 8450= 54 * 56 1/3= 3042

Step-by-step explanation:

Answer:

20

Step-by-step explanation:

This is an easy problem. All that is needed to do is you add up all the numbers, then divide that number by how many numbers you have.

Example: 17+24+26+13=80

80/4 = 20

Answer:

So the mean means the average of all the numbers, right? So that means all you have to do is add up all the numbers together, and divide by the amount of numbers there are.

so for this question...

17 + 24 + 26 + 13 = 80.

since it equals 80, and there are four numbers, (17, 24, 26, 13) divide 80/4.

80/4 = 20

your answer is 20!

i hope it helps u :-)

Answer:

225 and 243.4

Step-by-step explanation:

Area of triangle = bh/2

A = 4*4.6/2

A = 9.2 cm sq

A of 2 triangles = 9.2*2 = 18.4 cm sq

Now, Area of 1 rectangle = lb --> 15*5 = 75 cm sq

A of 3 rectangles = 75*3 = 225 cm sq

Now, LSA = 225 cm sq. (excluding the triangles)

TSA = A of tr. + A of rec. = 18.4 + 225 = 243.4 cm sq

Hope it helped. Pls mark me the BRAINLIEST! Don't fool pls

When we're solving with scale factors, we either divide or multiply.

If the shape becomes larger, we multiply to get the new length.

If the shape becomes smaller, we divide to get the new length.

We're given:

Because the shape becomes larger, we have to multiply the original side length by the scale factor, 6, to get the new side length.

2.5 x 6 = 15

Therefore, the missing side length is 15 units.

15 units

Answer:

6

Step-by-step explanation:

So we know the cost is $845, which means this is the cost or our C. Lets input this into our equation and solve.

845 = 45n + 125.

Subtract from both sides:

845-125 = 45n + 125-125

720 = 45n

Divide by 45:

720 / 45 = 45n / 45

16 = n

This means that 16 bracelets can be made if the cost is 845.

We can also re-input the information into the equation to be extra sure!

845 = 45 (16) + 125.

845 = 720 + 125.

845 = 845

Yes!

I hope this helps! :)

Step-by-step explanation:

Let the rhombus be $ABCD$, where $\angle DAB = 120^\circ$. Then $\angle ABC = 180^\circ - \angle DAB = 180^\circ - 120^\circ = 60^\circ$.

[asy] unitsize(1 cm); pair A, B, C, D; A = (0,1); B = (sqrt(3),0); C = (0,-1); D = (-sqrt(3),0); draw(A--B--C--D--cycle); draw(A--C); label("$A$", A, N); label("$B$", B, E); label("$C$", C, S); label("$D$", D, W); label("$6$", (A + D)/2, NW); [/asy]

Since $AB = BC$, triangle $ABC$ is equilateral. By the same argument, triangle $ACD$ is also equilateral. Each triangle has area

\[\frac{\sqrt{3}}{4} \cdot 6^2 = 9 \sqrt{3},\]so the area of the rhombus is $2 \cdot 9 \sqrt{3} = \boxed{18 \sqrt{3}}$.

Answer:

168°

Step-by-step explanation:

The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle, which is k, in this case.

m∠J = 78 and m∠L = 90° so the measure of exterior angle to ∠K:

78 + 90 = 168°

Answer:So I don’t know the other 5 points because you didn’t give the data about the age and number of US states named in 60 seconds, but using the 5coordinate points you gave, I was able to make this line of best fit.

So basically the units are counting up by 5.

The x axis is age in years and y axis is the number of US states named in 60 seconds.

Since you didn’t give me the data to make the other 5 points, I can’t really answer the last question, but from the graph that I did make, there are no points that would be considered outliers, and there are no clusters in sight.

(BTW THIS IS IMPORTANT!! - when you use the data to add the other 5 points, there might be an outlier or more then one outlier. And there might be a cluster. Just look at it after you graph the last 5 and change the answer I gave you if there is an outlier or cluster)

Answer:

To show that a reflected object is congruent to its preimage, follow these steps:

Identify the line of reflection.

Locate corresponding points on the preimage and its reflection.

Measure the distances between the line of reflection and the corresponding points.

Compare the distances for each corresponding point.

If the distances are equal, the reflected object is congruent to the preimage.

Step-by-step explanation:

Step-by-step explanation:

To show that a reflected object is congruent to its preimage, you need to demonstrate that the reflected object and the preimage have the same size and shape. Here's how you can do it:

1. Identify the preimage

2. Determine the line of reflection

3. Reflect the preimage

4. Compare corresponding points

5. Check angles

6. Verify sides

7. State the conclusion

By following these steps and ensuring that all corresponding points, angles, and sides are congruent, you provide a specific and comprehensive demonstration that the reflected object is congruent to its preimage.

Answer:Q(5,-2), S(-3,4)

Step-by-step explanation:

(-3,-4) is in the third quadrant so reflected over the x-axis results in it being in the second quadrant so only the y changing to positive giving you (-3,4)

(5,2) is in the first quadrant so when reflected over the x-axis it ends up in the fourth quadrant making y turn to negative giving you (5,-2)

Answer:

Q- (5,-2)  S- (-3,4)

Step-by-step explanation:

Answer: 4

Step-by-step explanation:

The prime factorisation is 2x2x2x2x2x2x2x2

We have to make triplets of the prime factorisation which gives us:

(2x2x2)x(2x2x2)x2x2

2x2 is left so we divide 256 by 2x2 which equals 4

let's try to divide 256 by 4:

256/4 = 64

The cube root of 64 is 4

64 = (4)³ so it makes a perfect cube

Answer:

Step-by-step explanation:

form. Meaning you need make both fractions improper

For explicit equations with the first term, you use the form \(f(n)=f_{1}+d(n-1)\). (f of 1 is the first term, d is the common difference, n is the step number)

However, since it is an admission fee before you go on rides, you do not need the -1 because it is not from the first term. Then, you can plug the values you know in.
