how many squares does it take to fill up a 5 5 box
1.5 2.7 3.10

Answer:

Step-by-step explanation:

Let the tenth digit is x and units digit is y.

We have the following equations:

Simplify the second equation:

Solve by substitution:

Find y:

The number is 27

Here the equations are if the digits be a and b

3(a+b)=10a+b

Equate both

And

The number is 27

Answer:

2 No

3 Yes 15 is divisible by 3, because 15 ÷ 3 = 5

4 No

5 Yes 15 is divisible by 5, because 15/5=3

9 No

10 No

Step-by-step explanation:

Answer:

No, yes, no, yes, no, no, no

Step-by-step explanation:

If you're looking for a perfect answer, no decimals or anything then this would be the right answer. 15 has the factors or 5, 3, 1 and 15. Technically, 15 is divisable by all these numbers, but the quotient isn't perfect...

Step-by-step explanation:

I dont know this part but i hope you can find it

Answer:

Step-by-step explanation:

So basically you have to do the Pythagorean Theorem here.

Which is =  a^2 + b^2 = c^2

So you'll put 35 in 'a' and 84 in 'b'

It'll be like this = 35^2 + 84^2 = c^2

So here, we are looking for 'c'

And 'c' is the hypotenuse

So,

Step 1: 35^2 + 84^2 = c^2

Step 2: You will use the exponents (but not for c)

=  1225 + 7056 = c^2

Step 3: You will now add 1225 + 7056 = 8281

Step 4: Now, square root 8281√8281 = 91

91 = c

Hope this helps! Please let me know if you get this correct!

First off, let's give our definitions to what we are doing here, so late this becomes more understandable to you

Algebra - the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Division - the action of separating something into parts or the process of being separated

Answer:

180

Step-by-step explanation:

8x15 is 120. The formula to find the area of a right triangle is base x height divided by two.
120/2 is 60
60x3 is 180.
180 plants

Answer:

For one of them, it will be B=(4.5, 1.5). The sides would each be 3.54 long.

For the second, B=(1.5,5.5). Lines AB and CB are also going to be 3.54 long.

Step-by-step explanation:

My thought process was all over the place, to be honest with you. I drew out the points on some graph paper and found out the length of AC, which is 5. Then I thought I could use the law of sines since we know that the other two angles are both 45 degrees. Anyways, I got the lengths as 3.5. I was a bit off, but I found that out later. I thought of using a compass to try to see where a point would meet if there is a distance of 3.5, but I don't have a compass, so I went searching for online ones. I couldn't find one with a graph in it, so I used an online graphing system. From the beginning, I knew that it was probably going to be something .5, so I kept on trying to find a spot that had a length of 3.5 on both sides, and got really close, but they were still off. I checked where B was graphed, and it was a really long decimal, so I just put it to .5 on both the y and x and voila, I got 3.54 on both lines AB and CB. I, of course, checked my answers and found that the angle was in fact 90 degrees and I felt very pleased with myself. I did a simpler version for the other angle.

I hope this is correct! Please let me know, this was really fun anyways!

Area of Triangle: 180 square units

Area of Semicircle: 314.15926536

Total Area: 494.15926536

Step-by-step explanation:

Answer:

Area of Triangle: 180

Area of Semi-circle: 157

Total Area: 337

Step-by-step explanation:

Area of triangle: 1/2(l x w)

1/2[(20) x (18)] = 180

Area of a semi-circle: 1/2(pi)(radius)²

1/2(3.14)(10)²

1/2(3.14)(100)

1/2(314)

157

((DON'T FORGET THAT IT'S ASKING FOR RADIUS AND NOT THE DIAMETER))

Total: add both areas

180 + 157

337

Answer:

1.9

Step-by-step explanation:

1.85 is expressed to 2 decimal places.  Since the '5' is ≥ 5, we round 1.85 UP to 1.9.

You are correct

Step-by-step explanation:

Area of parallelogram = b x h

= 12 x 20in = 240 in²

240 in² x 9 = 2160 in²

Answer:

According to the given attachment

L is a straight line and we know Sum of all angles formed on a straight line is 180° .

So,

➠ a + 90° + b = 180°

➠ a + b = 180° - 90°

➠ a + b = 90°

If angle a = angle b so we can easily find the value of a & b .

So, according to me " the given figure has not enough information to find out the value of a & b .

Answer:

c

Step-by-step explanation:

Answer:

1/12

Step-by-step explanation:

Total number of marbles = 5+7+4 = 16 marbles

Probability of picking a red marble = 5/16

Because the red marble is not returned back after being picked up, the total number of marbles is now 15.

Now,

Probability of picking a yellow marble = 4/15

The probability of picking a red and yellow marble will be the product of these two probabilities which will = 5/16 x 4/15 = 1/12

Answer:

c

Step-by-step explanation:

a: Using scale, divide the wing dimensions on the graph by 2 then multiply by 192cm

8.125/2 = 4.0625 x 192 = 780 cm

5/2 = 2.5 x 192 = 480 cm

Actual dimensions: 780 cm by 480 cm

Divide by 100 to convert to meters:

780/100 = 7.8 meters

480/100 = 4.8 meters

b: area of a triangle = 1/2 x base x height

area = 1/2 x 480 x 780 = 187,200 square cm

1/2 x 7.8 x 4.8 = 18.72 square meters

i did the dimensions in both cm’s and meters

Answer:

For A i would put 64 because its basically doing the total wing size divided by the number of sides it has.. And for B i havent thought of that yet..

Answer:

1/2 & 1/10

Step-by-step explanation:

Each of three:

15 outcomes have all three digits 1 through 8

So, 15/30 which is 1/2

Fewer than 2 is one or none being effective, i.e one or no digits are 1 through 8

There are only three such outcomes

So, 3/30 = 1/10

Answer:

I'm not totally sure what its asking, but here's a radio- 1:5

Answer:

y = x(5)

Step-by-step explanation:

Examples that prove this to be true are:

1(5) = y

y = 5$

2(5) = y

y = 10$

The reason this is correct is that it follows the same pattern on the graph.

Answer:

C) 9 and 6/12

Step-by-step explanation:

The easiest way to do this would be to turn both of the mixed numbers into improper fractions, this makes 6 and two sixths into 6 x 6 +2= 38/6 and 1 and one half into 1 x 2 + 1 = 3/2. From there multiple the numerators together (38x3) and the denominators together (6x2) to get 114/12. To turn this into a mixed number again, divide 114 by 12 to get 9 with a remainder of 6 to get 9 and six twelfths
