Mia buys ink at the office supply store for a business. She buys 3 printer cartridges, and the sales tax is 7%.
Write an expression to represent the total cost of ink supplies in two different ways. Let c represent the cost of a printer cartridge.

Answer:

21

Step-by-step explanation:

Given the radius (SV) = 10.5 cm, the diameter (RT) is 21 cm.

10.5(21) = 10.5(21)

The intersecting chords theorem or just The chord theorem is a statement in elementary geometry that describes a relation of the four line segments created by two intersecting chords within a circle. It states that the products of the lengths of the line segments on each chord are equal.

Answer:

1. The correct unit price of a pair = $1.12.

2. The error is taking the unit as 4 units instead of 48 units.

Step-by-step explanation:

a) Data and Calculations:

Cost of 4 dozen pairs of padded work gloves = $53.76

Each dozen pairs of the padded work gloves = $13.44 ($53.76/4)

Each pair of the padded work gloves = $1.12 ($13.44/12 or $53.76/48)

b) A dozen is made up of 12 units of something.  A dozen is an accepted unit of measurement that has persisted since time immemorial.  It originated from the practise of counting numbers in 12 instead of the current number system of 10.

Step-by-step explanation:

if it is direct proportion

Y=KX

16=K×-4

16/-4 =k

K=-4

then

Y=KX

4= -4×X

X= 4/-4

X= -1

Answer:

bus stop division really hard to show on here.

13/5

13 does not go into 5 so put a decimal point after the 5

13/5.000 carry the 5 over to the zero

13 goes into 50 3 times with 11 left over. carry the 11 over to the next zero. 13 goes into 110 8 times with 6 left over. carry over to the next zero. keep adding zeros and carrying over until the 13 goes into a number equally.

the answer is 0.38461538

Answer:

2 is the answer to you question

Step-by-step explanation:

Answer:

The given system of equations has infinitely many solutions.

Step-by-step explanation:

Given equations are:

4x-2y = 28

2x-y = 14

From equation 2:

[tex]2x-14 = y[/tex]

Putting in equation 1:

[tex]4x-2(2x-14) = 28\\4x-4x+28 = 28\\28 = 28[/tex]

When this happens in the solution of a system i.e. same constant on both sides of equation, the system of equations has infinitely many solutions.

Hence,

The given system of equations has infinitely many solutions.

The shape is a square that is tilted and looks like a rhombus. Just add the 5's together.

Answer:

i think is 12

Step-by-step explanation:

if sum 4x + 8 = 12x

u convert them youll get this

x = 12

Answer:

x = 95

Step-by-step explanation:

Given that,

Jax scores on the last 5 tests are 78,92,86,94,95.

We need to find the score he need to have an average of 90.

The formula for average of few number is given by :

Average = sum of observations/total no of observation

Let he score x in test 6. So,

[tex]90=\dfrac{78+92+86+94+95+x}{6}\\\\90=\dfrac{445+x}{6}\\\\540=445+x\\\\x=95[/tex]

So, he must score 95 in the next test so that its average is 90.

Answer:

[tex]x_{1[/tex]=-[tex]\sqrt{2}[/tex] , [tex]x_{2}[/tex]=[tex]\sqrt{2}[/tex]

Step-by-step explanation:

3[tex]x^{2}[/tex]-4=2

3[tex]x^{2}[/tex]=2+4

3[tex]x^{2}[/tex]=6  (divide both sides by 3)

[tex]x^{2}[/tex]=2 (simplify)

x=±[tex]\sqrt{2}[/tex]

Answer: a. This option is correct

b. This will be true only if we take the mode as the best representative value

c. This is a not correct choice

d. This option is correct

Answer:

Part A= 315

Part B= Saturday and Sunday

Step-by-step explanation:

Answer:

782

=

67

Step-by-step explanation:

Answer:

angle B = 90

Step-by-step explanation:

BC is a straight line which equals to 180 and C is 90 so you would take 180 minus 90 and would get 90

Step-by-step explanation:

3x²+10x+8 = 3x²+6x+4x+8

= 3x(x+2)+4(x+2)

= (3x+4)(x+2)

Answer: m= 100+5w

m= 80+7w

Step-by-step explanation:

Let w = number of weeks , m = Money required to buy DVD.

Total money = (Initial saving) + (Money saved per week) x (Number of weeks)

For Amir,

initial saving = $100 , Money saved per week =  $5

So,  m= 100+5w

For Pete,

initial saving = $80 , Money saved per week =  $7

So,  m= 80+7w

So, the required system of equations to find m and w:

m= 100+5w

m= 80+7w

Card #10: Quiesha is right

Card #6: Ulysses is right

Answer:

No, triangle P'Q'R' is not a 180° rotation about the origin of triangle PQR.

I got "coordinates" for the first drop down menu and I believe "are not" is the 2nd drop down.

Step-by-step explanation:

If you turn your device 180° (Basically upside down), and take a look at triangle PQR, it will not be in the place of where triangle P'Q'R' is when your device is not rotated.

Answer:

5

Step-by-step explanation:

7x plus 15 is 50

7x=35

can i pls have brainliest

Answer:

x = 5

Step-by-step explanation:

9x + 17 - 2x - 2 = 50

9x - 2x - 2 = 33

9x - 2x = 35

7x = 35

x = 5

Answer:

I would say 2,3,4.
