1.) Ivan made a scale drawing of his cell phone using the scale factor 1 mm = 2 in. How long is the drawing of his phone if the actual phones is 8 inches? Arecine for rice pudding calls for un

Answers

Using proportions, it is found that the length of his drawing is of 4 mm.

Proportions:This question is solved by proportions, using a rule of three.The scale means that each mm drawn corresponds to 2 inches of actual length. What is the length of the drawing if the actual length is of 8 inches?

The rule of three is:

1 mm - 2 in

x mm - 8 in

Applying cross multiplication:

[tex]2x = 8[/tex]

[tex]x = \frac{8}{2}[/tex]

[tex]x = 4[/tex]

The length of his drawing is of 4 mm.

Answer:

20%

Step-by-step explanation:

There are 5 medium shirts out of 25 shirts.

It need to be a percent instead of a decimal so you times it by 100.

3x – 4y = 2; 6x – 8y = 1 .

How many solutions PLEASE

Answers

Answer:

No solution

Step-by-step explanation:

3x - 4y = 2

6x - 8y =1

Multiply the first equation by -2 so you can eliminate the x's.

-2(3x-4y =2)

6x - 8y = 1

-6x + 8y = 2

6x - 8y = 1

Add the equations so they cancel.

0 + 0 = 3

0 [tex]\neq[/tex] 3, therefore there are no solutions.

Can someone please explain slope in a way that might make sense.

Answers

Okay let’s take the question “Find the slope of the points (4, 1) and (-2, 7)” as an example

The slope of an equation or graph is the rate of change.

In order to find slope, we use the formula m=rise/run or m=y2-y1/x2-x1

“m” is equal to the slope

“rise” or “y2-y1” is the difference (subtraction) of the two y coordinates

“run” or “x2-x1” is the difference (subtraction) of the two x coordinates

Remember, the points we are using for this example are (4, 1) and (-2, 7)

m = y2-y1/x2-x1
m = 7-1/-2-4

1 and 7 are your y coordinates so you plug them in an find the difference (subtraction)

4 and -2 are your x coordinates so you plug them in an find the difference (subtraction)

It doesn’t matter whether you do “m=7-1/-2-4” or “m=1-7/4-(-2)” both will have the same answer

The only thing you can’t do is something like “m=7-1/4-(-2)” or “m=1-7/-2-4”

The bottom can’t be solved in the opposite way of how it was solved on top and vice versa of that makes sense

Also, keep in mind that if you see two negatives as in the “m=1-7/4-(-2)” example, you turn it into an addition symbol

Like this:
“m=1-7/4+2)”

Because two negatives are equal to a positive

m = y2-y1/x2-x1
m = 7-1/-2-4
m = 6/-6
m = 6/-6
m = -1

Remember that a negative divided by a positive is always a negative so it doesn’t matter where you place the negative sign

For example, if your slope was 2/-5, that would be the same as -2/5

And when you divide two negatives, it always equals to a positive

For example -2/-5 would simplify to 2/5

I hope that helped and made sense :)

Riko wants to find the distance between the points (−2, −3) and (2, −5). His work is shown. StartAbsoluteValue negative 3 EndAbsoluteValue + StartAbsoluteValue negative 5 EndAbsoluteValue = 3 + 5 = 8. The distance is 8 units. Riko correct? Explain why or why not.

Answers

Answer:

Riko is wrong because she uses the wrong formula.

Step-by-step explanation:

Given the coordinate points (-2, -3) and (2, -5)

We are to find the distance between the two points

Using the formula:

D = √(x2-x1)²+(y2-y1)²

From the coordinates x1 = -2, y1 = -3, x2 = 2 and y2 = -5

Substitute

D = √(2-(-2))²+(-5-(-3))²

D= √(4)²+(-2)²

D = √16 + 4

D = √20

D = √4*√5

D = 2√5

This shows that Riko is wrong because she uses the wrong formula.

Answer:

No, Riko is not correct. The points do not have the same x-coordinates. If you connect the points, they do not form a horizontal or vertical line, so you cannot count spaces or use absolute value to find the distance.

Step-by-step explanation:

Aisha wants to paint the four walls of her living room.
Each wall is 2.4 m high and 3.7 m long.
One wall has a door of 2 m by 0.7 m.
Tins of paint cost £12 per 1.5 L tin.
Each litre of paint can cover 8 m2 of wall.
There is an offer of: Buy 2 tins get the 3rd at half price.
How much will Aisha pay to paint her living room?

Answers

9514 1404 393

Answer:

£30

Step-by-step explanation:

The total area of the four walls is ...

A = 4 × LW

A = 4 × (2.4 m)(3.7 m) = 35.52 m²

Subtracting the area of the door, we find the painted area to be ...

35.52 m² -(2 m)(0.7 m) = 34.12 m²

Painting this area will require ...

(34.12 m²)/(8 m²/L × 1.5 L/tin) = 2.8433... tins

Aisha will need to buy 3 tins of paint, for which she pays 2.5 times the price of 1 tin:

2.5 × £12 = £30 . . . . Aisha's cost to paint her living room

£25 or £20.10

Step-by-step explanation:

calculate the area to be painted:

2.1x4.5= 9.45m^2 for each wall

x4= 37.8m^2

area of door= 1.8x0.9= 1.62m^2

subtract the area of the door from the wall area

37.8-1.62= 36.18m^2 to be painted

divide the area by the area that 1L of paint can cover

16.18/12= 3.015 L needed

if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L- so another can (3 cans total) add price up.

£30- but buy 2 get 3rd 1/2 price, so take £5 off. price is £25

calculate price for 0.015L

1.5=£10

divide both sides by 100

0.015= £ 0.10

if 1.5L= £10 then, 3L= £20. she needs 2 cans + an extra 0.015 L

£20+£0.10= £20.10
