Answer:

1) b. 1.562x10⁸

2) a. 4.8x10⁶

4) d. 2.3x10³

5) a. 4.21x10 -⁶

6) 6.6835x10⁵

Step-by-step explanation:

1) (2.2x10⁴)•(7.1x10³)= 156200000

2) 9.6x10⁹÷2x10³= 4800000

4) 6.9x10⁸= 2300

5) 5.6x10 -⁷ + 3.65x10 -⁶= 4.21x10 -⁶

6) 6.72x10⁵ - 3.65x10³= 668350

Answer:

1+18-11+16

Step-by-step explanation:

if the elevator went up it will be plus but if the elevator came down it will be minus and then you will get 1+18 because it went up and then it go down 11 floor and it will be 1+18-11 and then it went up again 16 floor so the last answer will be 1+18-11+16

2.743 x 10 6

Step-by-step explanation:

Answer:

2.743 x 10^6

Step-by-step explanation:

Answer:An important category of percentage exercises is markup and markdown problems. For these, you calculate the markup or markdown in absolute terms (you find by how much the quantity changed), and then you calculate the percent change relative to the original value. So they're really just another form of "increase - decrease" exercises.

Step-by-step explanation:

Answer:

45%

Step-by-step explanation:

O= 160

C=88

160-88=72

72       ?

160    100

72 times 100=7200

7200/160=45

Answer:

84.3

Step-by-step explanation:

843 ÷ 10

The place value of 843 is

8 = Hundreds

4 = Tens

3 = Units or ones

Hence,

843 ÷ 10

= 843/10

= 84.3

Answer:

Correct: Option a. negative reciprocals

Step-by-step explanation:

Perpendicular lines are defined as those who intersect at an angle of 90°.

There is an easy way to find out if two equations of lines correspond to perpendicular lines or not.

If line 1 is

y=m1x+b1

And line 2 is:

y=m2x+b2

The condition for the lines to be perpendicular is that:

m1*m2=-1

Solving for m2:

[tex]\displaystyle m2 = -\frac{1}{m1}[/tex]

As seen, both slopes are negative reciprocals.

Correct: Option a. negative reciprocals

Answer:

C

Step-by-step explanation:

just is lol please make me brainliest

Answer:

c.  (-4, 4)

Step-by-step explanation:

y = 0.8x + 7.2

20x + 32y = 48

20x + 32y = 48

20x + 32(0.8x + 7.2) = 48

20x + 25.6x + 230.4 = 48

45.6x + 230.4 = 48

45.6x = -182.4

x = -4

y = 0.8x + 7.2

y = 0.8(-4) + 7.2

y = -3.2 + 7.2

y = 4

Answer:

C. (-4,4)

Step-by-step explanation:

Because i did it and got it right on (Edge)

300

1:1

1*300:1*300

300:300

Whenever the two numbers in a ratio are the same it means that they're equal. Hope this helps :)

Answer:

B. y=1/3x+4

Step-by-step explanation:

The graph shows a line with a slope of -3. Perpendicular slopes is the reciprocal with a different sign (positive or negative). The perpendicular of -3 is 1/3, and B. is the only option with this slope.

Answer:

Maximum of 50 persons

Step-by-step explanation:

Straight line equation

let the total prices be y

and the number of persons be x

1.  Brenda's Bridal Catering charges

the expression for the charges is

y=mx+c

y=18x+300---------------1

2.  Sarah's Complete Catering charges

the expression for the charges is

y=mx+c

y=15x+450---------------2

equating 1 and 2 we can then solve for the number of guest as

18x+300=15x+450

18x-15x=450-300

3x=150

divide both sides by 3

x=150/3

x=50

x<=50

Therefore she can invite a maximum of 50 persons

Answer:

y = 11t + 8

Step-by-step explanation:

Since the starting fee is 8 dollars and the additional costs are 11 dollars per ticket, you can write the equation as:

y = 11t + 8

Where "t" represents the amount of tickets bought.

Answer:

Simplify each side of the equation as much as possible. ...

Collect all the variable terms on one side of the equation. ...

Collect all the constant terms on the other side of the equation. ...

Make the coefficient of the variable term to equal to 1. ...

Check the solution.
