(a) 34 is 85% of what number?
(b) What is 15% of 80?

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:

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

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.

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:

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

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...

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:

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:

The First one

WHY:

Because you are trying to find h!

Hope this Helps!

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!

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:

Step-by-step explanation:

I just guess because school is unfair basically

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:

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
