A computer and printer cost a total of $900. The cost of the computer is three times the cost of the printer. Find the cost of each item.

Answers

Answer 1
P = printer cost
C = computer cost
P + C = 900
C = 3P

P + 3P = 900
4P = 900
P = $225

C = 3(225)
C = $675

Answers

Answer:

55

Step-by-step explanation:

along line s, r intersects it, and you can see a right angle

90+35+angle 2 =180

you end up with 55, which is the measure

The answer is 55 this is because it’s a90 degree angle but the 90 degree angle is split so you have to find the other half of the angle so you do 90 minus 35 and you get your answer of 55

Mick and Jackie buy a large sandwich to share. They each eat 2/5 of the sandwich.

How much of the sandwich is remaining?
Show your work.

Answers

Answer:

1/5 is remaining

Step-by-step explanation:

if there is two people each eating 2/5 we would just multiply 2/5 by 2 and get 4/5 then we would subtract 4/5 from 1 and get 1/5

Answer:

1/5

Step-by-step explanation:

Sandwich eaten by Mick and Jackie = [tex]\frac{2}{5}+\frac{2}{5}\\\\[/tex]

                                                             = [tex]\frac{2+2}{5}=\frac{4}{5}[/tex]

Remaining sandwich = 1/5

2.) 15x18+12/3+9

Answers

Answer:

283

Step-by-step explanation:

15(18) + 12/3 + 9

270 + 4 + 9 = 283

Answer:

283

Step-by-step explanation:

First, we have the equation 15 × 18 + 12/3 + 9.

If we refer to PEMDAS, division comes first, then multiplication, addition, and subtraction.

So, the equation becomes 15 × 18 + 4 + 9.

Now, we can multiply 15 × 18 in the equation.

The equation becomes 270 + 4 + 9.

4 + 9 = 13.

270 + 13 = 283.

Answers

Answer: After 13 (12) hours, there would be 6,500 bacteria across the culture.

Step-by-step explanation:

The bacteria grew by 500 each 4 hours, so to know how much there would be 13 hours later:

Simple, add 500 bacteria to every 4 hours until you reach 13 hours. 4 = 5.5k, 8 = 6k, 12 = 6.5k. Now, 12 is closer to 13 than anything we would've gotten if we kept going.

A TV has a length of 68 inches and a height of 51
inches. When TV's are advertised the size listed is the
diagonal length. What would be the advertised size of
this TV?

Answers

Answer:

85 inches

Step-by-step explanation:

Using pythag.  A^2 + B^2 = C^2  

(68*68) + (51*51) = 7225^2

Thus if you square root 7225, you get your answer - 85 inches.

Find the zeros

Answers

Answer:

The zeroes of this polynomial are [tex]x_{1} \approx 0.847[/tex] and [tex]x_{2} \approx -1.180[/tex].

Step-by-step explanation:

Let [tex]3\cdot x^{2}+x - 3 = 0[/tex], the quickest and most efficient approach to find the zeroes of this second order polynomial is by Quadratic Formula. For all [tex]a\cdot x^{2}+b\cdot x + c = 0[/tex], roots are determined by:

[tex]x_{1,2} = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex] (1)

Where [tex]a[/tex], [tex]b[/tex], [tex]c[/tex] are coefficients of the polynomial.

If we know that [tex]a = 3[/tex], [tex]b = 1[/tex] and [tex]c = -3[/tex], then roots of the polynomial are, respectively:

[tex]x_{1,2} = \frac{-1\pm\sqrt{1^{2}-4\cdot (3)\cdot (-3)}}{2\cdot (3)}[/tex]

[tex]x_{1,2} =\frac{-1\pm \sqrt{37}}{6}[/tex]

The zeroes of this polynomial are [tex]x_{1} \approx 0.847[/tex] and [tex]x_{2} \approx -1.180[/tex].
