What do all rhombuses have in common

Answers

Every rhombus has two diagonals connecting pairs of opposite vertices, and two pairs of parallel sides. 

All rhombuses have equal sides and diagonals that bisect each other at right angles.

We have,

All rhombuses have the following characteristics in common:

- Equal Sides:

A rhombus is a quadrilateral with all four sides of equal length.

Each side of a rhombus has the same measurement.

- Opposite Angles are Equal:

The opposite angles of a rhombus are congruent (equal in measure). This means that if we label the angles A, B, C, and D in a clockwise or counterclockwise direction, then angle A is congruent to angle C, and angle B is congruent to angle D.

- Diagonals Bisect Each Other:

The diagonals of a rhombus are perpendicular bisectors of each other. This means that the diagonals intersect at a right angle, and they divide each other into two equal halves.

- Diagonals are Equal in Length:

The two diagonals of a rhombus are of equal length. If we label the endpoints of the diagonals as E, F, G, and H, then EF = GH.

Thus,

All rhombuses have equal sides and diagonals that bisect each other at right angles.

Step-by-step explanation: I used the formula A=1/2(b1+b1)h and I filled it in by doing A=1/2(6+12)6 and then I divided the height by 1/2 and i multiplied 72 by 3 which is 216 in.

Suppose an and bn are series with positive terms and bn is known to be convergent. (a) If an > bn for all n, what can you say about an ? Why? an converges by the Comparison Test. We cannot say anything about an . an diverges by the Comparison Test. an converges if and only if an ≤ 4bn. an converges if and only if an ≤ 2bn. (b) If an < bn for all n, what can you say about an ? Why? an diverges by the Comparison Test. an converges if and only if bn 2 ≤ an ≤ bn. We cannot say anything about an . an converges by the Comparison Test. an converges if and only if bn 4 ≤ an ≤ bn.

Answers

Answer:

a. i. We cannot say anything about aₙ

ii. we do not know if the terms of aₙ are increasing or decreasing

b. i. aₙ converges by the Comparison Test.

ii. aₙ also converges since bₙ.

Step-by-step explanation:

(a)

i) If aₙ > bₙ for all n, what can you say about aₙ ? Why?

We cannot say anything about an.

ii) Why?

This is because since ∑bₙ converges, ∑aₙ > ∑bₙ, we do not know if the terms of aₙ are increasing or decreasing, so we have no information about it.  

(b) If aₙ < bₙ for all n, what can you say about aₙ ? Why?

i) aₙ converges by the Comparison Test.

ii) Why?

This is because since ∑bₙ converges, and ∑aₙ < ∑bₙ, we know that the terms of aₙ are also decreasing and, by the comparison test, aₙ also converges since bₙ.

What is the rate of change of the function?
A
2
B
34
с
17
D
0.5

Answers

Answer:

Step-by-step explanation:

The rate of change, slope, m is

m=(y2-y1)/(x2-x1), we have points (4,5) and (21,39) so

m=(39-5)/(21-4)

m=34/17

m=2

So the rate of change is 2

Answers

Answer:

384 cm²

Step-by-step explanation:

The shape of the figure given in the question above is simply a combined shape of parallelogram and rectangle.

To obtain the area of the figure, we shall determine the area of the parallelogram and rectangle. This can be obtained as follow:

For parallelogram:

Height (H) = 7.5 cm

Base (B) = 24 cm

Area of parallelogram (A₁) =?

A₁ = B × H

A₁ = 24 × 7.5

A₁ = 180 cm²

For rectangle:

Length (L) = 24 cm

Width (W) = 8.5 cm

Area of rectangle (A₂) =?

A₂ = L × W

A₂ = 24 × 8.5

A₂ = 204 cm²

Finally, we shall determine the area of the shape.

Area of parallelogram (A₁) = 180 cm²

Area of rectangle (A₂) = 204 cm²

Area of figure (A)

A = A₁ + A₂

A = 180 + 204

A = 384 cm²

Therefore, the area of the figure is 384 cm²

A total of P60,000 was invested, a portion at 5% and the remainder at 4.5%. The total amount of interest earned was P2,900. How much was invested at each rate?

Answers

Answer:

P40000 at 5%

P20000 at 4.5%

I am curious as to what the P stands for.  Can you tell me?

Step-by-step explanation:

Let x = amt. invested at 5%

     y = amt. invested at 4.5%

(1)         x + y = 60000                  (2)      .05x + .045y = 2900

                                                                   50x + 45y = 2900000

                                     -45 times (1)        -45x - 45y = -2700000

                                                                    5x = 200000

                                                                      x = 40000

          40000 + y = 60000

                        y = 20000

Answer:

The 20-count batteries have a lower unit price of $0.76 per battery

Step-by-step explanation:

Unit price means how much does it cost if you buy one of the item. To calculate this take the amount of money it cost and divide by the amount of object you have.

In the case of this question we know that you can buy 8 batteries for $6.16 and 20 batteries for $15.20. Let's find the unit cost (how much for one battery) for each of these packs. To calculate that we can take $6.16/8 batteries = $0.77 per battery for the 8 pack and $15.20/20 = $0.76 per battery for the 20 pack. Therefore, the 20-count batteries have a lower unit price of $0.76 per battery.

What does X and Y equal?

Answers

Answer:

Triangles sum up to 180°.

180/3= 60

60+7= 67

x=67

Triangle TRS is an isosceles triangle which means it has two equal sides.

Triangles sum up to 180°.

180-60= 120

TRS= 120°

60/2= 30°

RTS=  30°

RST=  30°

Janie walks 1 mile to get to a running track.she then runs at a speed of 3.5 miles per hour.Which linear models represents the total distance she ran and walked, d, as a function of t, the time she runs,in hours?

Answers

Answer:

d = 3.5t + 1

Step-by-step explanation:

The linear function would have to multiply the speed she runs at the track by the number of hours that she spent running. Then it should add this amount to the 1 mile that she walked to get to the track. If we use the variable d as the total distance that she ran and walked, and the variable t to represent time then we would create the following linear function/model.

d = 3.5t + 1
