d) When will Jessie & Riley have the same number of records in their collection?



How many records will they each have at this time?

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:

a = -31

Step-by-step explanation:

According to the question,

-6a + 7a = -31

a = -31

Answer:

No solution

Step-by-step explanation:

x+5x+4=3(2x-1)

First off, rearrange:

6x+4=6x-3

The '6x's cancel out (4=-3, incorrect), which means the equation has no solution.

Answer:

D)

Step-by-step explanation:

Substitute it into equation, for (-1,1): -2*(-1) - 1 = 2 -1 = 1, and -2*4 - 1 = - 8 -1 = -9, so D) is correct.

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

Answer:

X = 50

Step-by-step explanation:

2/5x = 20

x = 20÷2/5

x = 20 × 5/2

x = 10 × 5

x = 50

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.

Answer:

[tex]SA=61.26\ \text{inches}^2[/tex]

Step-by-step explanation:

The surface area of a cylinder is given by :

[tex]SA=2\pi r^2+2\pi rh[/tex]

Where

r is radius and h is height of the cylinder

We have, h = 5 inches and r = 3/2 = 1.5 inches

Put all the respected values.

[tex]SA=2\pi \times (1.5)^2+2\pi \times 1.5\times 5\\\\SA=61.26\ \text{inches}^2[/tex]

So, the surface area of the cylinder is equal to [tex]61.26\ \text{inches}^2[/tex].

Supplementary Angles

Step-by-step explanation:

Two (or more) angles whose

sum is 180°

Answer:

X= 67

Y= 6

Step-by-step explanation:

Triangle TRU is an equilateral triangle which means all sides are equal.

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°

30/5= 6

y= 6

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

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

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.
