The ratio of the sides of a triangle is 2:4:9. If the perimeter is 165 inches, what is the length of the longest side?

Answer:

5cm

Step-by-step explanation:

diameter=10cm

radius is 1/2 of diameter

10/2=5

Answer:

4x + 3 = 11

4x = 11 - 3

4x = 8

x = 8 ÷ 4

x = 2

3x - 5 = 7

3x = 7 + 5

3x = 12

x = 12 ÷ 3

x = 4

8x - 5 = -37

8x = -37 + 5

8x = -32

x = -32 ÷ 8

x = -4

7(x - 3) = 21

7x - 21 = 21

7x = 21 + 21

7x = 42

x = 42 ÷ 7

x = 6

Correct question is;

John makes clay cups. He makes 18 cups each hour.

He makes cups for 6½ hours each day, on 5 days of the week.

The cups are packed in boxes.

4 cups are packed into each box.

How many boxes are needed for

all the cups John makes in a week?

585

146.25

146

147

Answer:

147

Step-by-step explanation:

Since he makes 18 cups each hour and we are told that he makes it for 6½ hours each day.

Thus, amount of cups made per day = 18 × 6½ = 18 × 13/2 = 117 cups

She works 5 days a week.

This means;

Cups produced for the week = 117 × 5 = 585 cups

We are told that the cups are to be packed in boxes. Also that 4 cups are packed into each box.

Thus, number of boxes = 585/4 = 146.25 boxes

Since, we can't have a decimal as number of boxes, to fit everything we approximately need 147 boxes

Step-by-step explanation:

===================================================

Explanation:

Let's compute the slope of the line through the two original points

m = (y2-y1)/(x2-x1)

m = (4-10)/(7-(-2))

m = (4-10)/(7+2)

m = -6/9

m = (-2*3)/(3*3)

m = -2/3

The slope is -2/3

-------------

Now apply the scale factor.

We'll multiply each coordinate of each point by 2

(-2,10) becomes (-4,20) after multiplying each coordinate by 2

(7,4) becomes (14,8) after multiplying each coordinate by 2

Let's find the slope of the line through (-4,20) and (14,8)

m = (y2-y1)/(x2-x1)

m = (8-20)/(14-(-4))

m = (8-20)/(14+4)

m = -12/18

m = (-2*6)/(3*6)

m = -2/3

We get the same slope. This isn't a coincidence. Dilating a set of points will preserve the slope of the line through those points.

If A and B are the two original points, and A' and B' are the dilated counterparts, then the slope of line AB is the same as the slope of line A'B'.

The scale factor doesn't affect the answer.

Answer: i think the answer is 320

Step-by-step explanation:

i say 320 because a square has 4 sides and there is 80 yards so all i did is multiply 80 x 4 = 320

Answer:

Step-by-step explanation:

[tex]d^2=x^2+x^2\\ \\ 2x^2=80^2\\ \\ 2x^2=6400\\ \\ x^2=3200\\ x=\sqrt{3200}\\ \\ P=4x\\ \\ P=4\sqrt{3200}yds\\ \\ P\approx 226.27yds[/tex]

Answer:

[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex]

Step-by-step explanation:

We know that [tex]x[/tex] and [tex]y[/tex] are directly proportional. Therefore, using the given information, we can set up the following proportion:

[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]

Solving for [tex]y[/tex], we get:

[tex]\frac{6.5}{12}=\frac{y}{4}[/tex]

[tex]12*y=6.5*4[/tex] (Cross-Products Property)

[tex]12y=26[/tex] (Simplify)

[tex]\frac{12y}{12} =\frac{26}{12}[/tex] (Divide both sides of the equation by [tex]12[/tex] to get rid of [tex]y[/tex]'s coefficient)

[tex]y=2\frac{1}{6}[/tex] or [tex]\frac{13}{6}[/tex] (Simplify)

Hope this helps!

Step-by-step explanation:

They subtracted 5 on both sides of the equation. They were suppose to add 5 on both sides of the equation for it to cancel out each other. If you need any further explanation, please ask me :)

Correct version:

5y + (-5) = 10

       +5     +5    add 5 to both sides, 5's will cancel out on left side.

___________

5y     15

__ = __        divide 5 on both sides, 5's will cancel out on left side.

5      5

y = 3, final answer

Answer:

its the first part the (-5) -5  is supposed to be (-5) +5

Step-by-step explanation:

so the equation is 5y=15

then you divide 5y/5 is y so then you 15/5 is 3

so the answer is y=3
