3. a. 13 inches        b. I'm pretty sure that it is the second quarter because there is more snow.           c. The first quarter because it's section is more spread out among the numbers.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

Because it is negative it goes backwards, so it would be on the left side of -15. It doesn't go in the middle because that would be -15 1/2. It does go on the left side of the middle, because that would be -15 3/4. It goes on the right side of the middle because that is -15 1/4.

Answer:

C

Step-by-step explanation:

Since its negative then your going backwards and 1/4 is less than half.

Answer:

11.1 cm

Step-by-step explanation:

draw the triangle with a base length as 10cm and mark a 15cm with the compass on the mark A and also draw a straight line forming a right angle at B and connect the two lines with another straight line at which the vertex is C. at last measure the line.

Answer:

h=square root of 55

area of triangle=15*square root of 5

Step-by-step explanation:

Answer:

a. 7.4 cm

b. 22.2 cm²

Step-by-step explanation:

a. Apply Pythagorean theorem to find h.

c² = a² + b²

Where,

c = 8 cm

a = 3 cm

b = h cm = ?

Plug in the values

8² = 3² + h²

64 = 9 + h²

64 - 9 = h²

55 = h²

h = √55

h ≈ 7.4 cm

b. Area of the triangle = ½*bh

b = 6 cm

h = 7.4 cm

Area = ½*6*7.4

Area = 22.2 cm²

Answer:

The average speed on the second part was 30 mph.

Step-by-step explanation:

The whole trip between New York and Washington is 120 miles. On the first part he drove at 50 mph for 1.5 h, from 7 AM to 8:30 AM, therefore he drove a distance of:

distance = speed*time = 50*1.5 = 75 miles

So the second part had a length of 120 - 75 = 45 miles. With an elapsed time of 1.5h, therefore the average speed was:

speed = distance / time

speed = 45 / 1.5

speed = 30 mph

The average speed on the second part was 30 mph.

Answer:

5/6 more meters

Step-by-step explanation:

Find the perimeter of the wardrobe (Add all the sides together) and you get 4 5/6 m.

Subtract 4 meters because she already has 4 meters of ribbon.

4 5/6 - 4 = 5/6

Answer:

Step-by-step explanation:

P = (2/3)*2 + (7/4)*2                      (1 3/4 = 7/4)

4/3 + 14/4

= 16/12 + 42/12

= 58/12

= 29/6

= 4 5/6

She already has 4 m of ribbon

4 5/6 - 4 = 5/6 m or ribbon needed

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

240

Step-by-step explanation:

Answer:

240²

Step-by-step explanation:

Okay, so we can split this up into the triangle at the top, and the rectangle on the bottom, so:

4 x 20 ÷ 2 = 40

20 x 10 = 200

40 + 200 = 240

so the area of the shape is 240²

Step-by-step explanation:

Answer:

The customer is incorrect. They will pay $43.20 not $40.

Step-by-step explanation:

Since a thrift store is having 40% of $80, we have to calculate that. Doing so, we have to create proportions:

(The "/" sign is fraction)

1. x/80=40/100       2. 40*80=3200      3. x*100=100x       4. 100x=3200      

5. x=3200/100       6. x=$32

Since $32 is 40% of $80, we have to do $80-$32=$48

So the thrift shop is lowering the price to $48.

But we can't forget about the 10% off coupon from the customer.

Now we have to find out what is 10% of $48. $48/10= $4.8

That's not our answer though. The final step is to do $48-$4.8 which gets our answer of $43.20   .

Answer:

1st, 2nd, and 5th box

Step-by-step explanation:

Answer: The three angles choice.

Step-by-step explanation:

First we need to remove the measures that can't create a triangle.

3, 5, 10 cm sides.

First of all, This is impossible. 3+5=8, which means that 10 is too large of a side to create a triangle.

Now the other ones can either create one or infinite.

Two sides: 4, 7 cm and angle 54 between them.

tan(54) = o/7 ; o = 7(tan(54)) = 9.63

OR

tan(54) = o/4 ; o = 4(tan(54)) = 5.5

There are two possible triangles, but not infinite.

3, 5, 7 ; The parameters work, but there's only one possible triangle here.

The three angles can create infinite number of triangles, since there's an infinite number of side lengths that can fit these angle proportions.

Answer: The three sides one.

I think you're missing the question

Answer:

I am not sure but I think it is 3/16 or A

Step-by-step explanation:

3/4 x 1/4 = 3/16

Answer:

3/16 is the answer

Step-by-step explanation:

Multiply both sides of the equation by 4.

Subtract 24 from both sides.

Subtract 24 from 32 to get 8.

Answer:

p = 8

Step-by-step explanation:

p/4 + 6 - 6 = 8 -6

6-6 cancels out as 0.

8-6=2

p/4 = 2

p/4 * 4= 2*4

/4 * 4 cancels out as 0

2 * 4 = 8

So, p = 8

Answer:

Yes you are correct, the answer is D

Step-by-step explanation:

the answer is still 420 regardless if you do :

\(42*(3.5+1.3+5.2)\\\)

or

\((42* 3.5)+(42* 1.3)+(42 *5.2)\)

Answer: It will take her 13 more days.

Step-by-step explanation:

1. 35/7 = 5

2. So that means every day she reads 5 percent of her book.

3. 100-35=65

4. She has 65% more of her book to read

5. 65/5 = 13

6. It will take 13 more days to complete the book.

____________________________________

\( \large \tt Solution \: : \)

Proprtional relationship can be depicted as :

\(\qquad \tt \rightarrow \: y \propto x\)

[ to get rid of proportionality sign, we use constant c ]

\(\qquad \tt \rightarrow \: y = cx\)

Now, conclusion can be made that the shown equation represents a straight line.

And the graph has two straight lines, which means proportional relationship is shown by Two members
