HELP ILL GIVE BRAINLIEST!!! i need this rlly soon so im rlly desperate to give whoever answers this a brainliest and 5 stars and 15 points! ;-;

Answer:

~0.143

Step-by-step explanation:

So, in total there are 15 marbles, and only 6 of them are red. So the first draw will have a  chance of being red. Since you didn't mention placing it back, the next draw will have a  chance of being red. It's  , because you just took a red one out of the bag (leaving 5 left) and the total was lessened by one. To get the answer, you'd multiply both numbers together.

6/15 x 5/14 = 1/7 or (roughly) 0.143

Answer:

3(5k+3), 6k+9+27k

Step-by-step explanation:

Answer:

Try 22.52.

Step-by-step explanation:

P-9=13.52

-9+9 (Cancels)

13.52+9= 22.52

22.52-9= 13.52

Answer:

Total area = 26.13 ft²

Step-by-step explanation:

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

From inspection, the base of the triangle = 3 x 2 = 6

and the height of the triangle = 4

⇒ area = 1/2 x 6 x 4 = 12 ft²

area of a semicircle = [tex]\frac{1}{2}\pi r^2[/tex]

⇒ area = [tex]\frac{1}{2} \times 3.14 \times 3^2[/tex]

⇒ area = 14.13 ft²

Total area = 12 + 14.13 = 26.13 ft²

Answer:

(i) The factors of the given polynomial is (x – 22) and (x + 10)

(ii) If she purchase 5kg papaya then she pays 110

Step-by-step explanation:

Now,

x² – 12x – 220 = 0

Splitting the middle term

x² – 22x + 10x – 220 = 0

x(x – 22) + 10(x – 22) = 0

(x – 22) + (x + 10) = 0

x – 22 = 0 or x + 10= 0

x = 22 or x = -10

Here, (-10) is the negative value hence it is not possible

So, The value of x is 22

The factors of the given polynomial is (x – 22) and (x + 10)

if she purchase 5kg papaya then,

we know the price of 1 kg papaya i.e., 22 per kg

So,

5 × 22 = 110

Thus, if she purchase 5kg papaya then she pays 110

Answer:

0%

Step-by-step explanation:

Don't quote me on that but I'm pretty sure

Heya!

2x + 4 > 16

2x > 16 - 4

2x > 12

x > 12 ÷ 6

x > 6

Hope it helps ya!

Answer:

16 students

Step-by-step explanation:

Knowing that 4 is 20% of a certain number is a great start. Think, how many times does 20 go into 100, 4. So then you multiply 4 with 4.

4 · 4 = 16

Answer: y is a variable and is represents an unknown number.

Step-by-step explanation:

Answer:

(5r-2)/3 = s

Step-by-step explanation:

-6= -15r+9s

Add 15r to each side

-6+15r= -15r+15r+9s

15r-6 = 9s

Divide each side by 9

(15r-6)/9 = 9s/9

(5r-2)/3 = s

Answer:

the two numbers are 5 and 17

Step-by-step explanation:

4y - 3 = x

x - 2y = 7

to find y:

x - 2y = 7

(4y - 3) - 2y = 7

2y - 3 = 7

2y = 7 + 3

2y = 10

y = 10/2

y = 5

to find x :

4y - 3 = x

4 ( 5 ) - 3 = x

20 - 3 = x

17 = x

Answer:

1) X + 234 = 633

2) t = 63

3) x = 12

Step-by-step explanation:

1 is simple subtraction, just subtract the whole by the number that is given. Then that will fill X.

2 is multiplication. If a variable is (for example, x) next to a number that means it is multiplying it by a hidden number. To find that, you multiply the number next to the variable. If the sum matches the solution, there you go.

Answer:

  40 in

Step-by-step explanation:

The Pythagorean theorem tells you the relationship between the sides of a right triangle.

  b^2 +75^2 = 85^2

  b^2 = 85^2 -75^2 = 1600

  b = √1600 = 40

The length of the missing side is 40 inches.

Answer:

$1,824

Step-by-step explanation:

Games Dave wants to buy: 5

Cost of each game: $50

Cost of 5 games = $50 x 5

= $250

Funko pops Dave wants to buy: 10

Cost of each funko pop: $30

Cost of 10 funko pops = $30 x 10

= $300

Toys Dave wants to buy: 6

Cost of each toy: $40

Cost of 6 toys = $40 x 6

= $240

Sum of all Dave's things = ($250 + $300 + $240)

= $790

Money Dave has = $2,614

Money left with him = ($2,614 - $790)

= $1,824

Hence, $1,824 are left with Dave after buying 5 games, 10 Funko pops and 6 toys.

Pls correct me, if I am wrong :)

Have a great day!

Thanks!

Answer:

5x^2-8x + 12

Step-by-step explanation:

the formula for finding roots of equation is

x^2- (sum of roots)x + products of roots =0

and we already have the roots of the equation

so we add them to give 8

and multiply to give 12

hence the quadratic equation that has those roots with leading coefficient is 5x^2-8x + 12=0

Step-by-step explanation:

Solution,

In the given cuboid, area of total surface (A)=280 cm²

Breadth ( b ) = 5 cm

Height ( h ) = 6 cm

Total surface area of cuboid = 2 ( lb + bh + lh )

or , Area = 2 ( lb + bh + lh )

or , 280 = 2 ( l × 5 + 5 × 6 + l × 6 )

or , 280 = 2 ( 11 l + 30 )

or , 2 ( 11 l + 30 ) = 280

or , 11 l + 30 = 280 ÷ 2

or , 11 l + 30 = 140

or , 11 l = 140 - 30

or , 11 l = 110

or , l = 110 ÷ 11

l = 10

Thus, the length is 10 cm...

Answer:

First option) y= 2x - 3

Step-by-step explanation:

[] The y-intercept, our b, is -3. This does not rule out any of the options as they all have -3.

[] The slope, when we have a graph with clear points, can be found with rise-over-run. We will pick a point and then count up and over to the next point.

-> Starting at the y-intercept, (0, 3), we count up 2 and to the right 1 for a slope of 2/1. This simplifies to 2.

[] Our equation is y = 2x - 3

Have a nice day!

Answer:

Step-by-step explanation:

Correct option is C)

19% of all the survey respondents implies we find out 19% of 310.

19% of 310=310×

=58.9 which is approximately equal to 59.

Seen from the table, 59 is the number of males taking geometry.

Answer:

im guessing it is 78/100 because u circled 78

Step-by-step explanation:

because 21 + 1 + 78 = 100

so 78/100 is the fraction

Answer:

78/100 or 39/50 (simplified)

Step-by-step explanation:

First, let's convert 78% into a decimal.

Now, we know that 0.78 is the same thing as 78/100. We can simplify 78/100 into 39/50, where 2 is the GCF

Thus, the answer is 78/100 or 39/50.

Answer:

D.  1/12^-4

Step-by-step explanation:

[tex]12^{-5}*12^{9}[/tex]

Since both exponents have the same base, we can add the exponents to get:

[tex]12^{-5+9}=12^{4}[/tex]

We can cross out A and B since they multiplied the two exponents, therefore both answers are wrong.

Now, let's try C and D.

C is wrong because it has a different base being raised to the same power.

D is correct. When you have a negative exponent, it is equivalent to the reciprocal of the base to the positive exponent.

The reciprocal of 1/12 is 12, and the positive of -4 is 4, therefore the answer is D.

Answer: Evaluate

Step-by-step explanation:

Answer:

It is parallel and yes you can prove it.

Step-by-step explanation:

I would use a tool that you can use to figure out the angle, check all the corners and if the smaller one are the same and the wider corners are the same then then would be parallel. That only works though if there was a line going through like your problems. If you had a graph it would be easier.

definitely missing a number so it's prolly something like

a/20=20

sorry if this doesn't help you didn't give us much to work on

Answer:

3 7/8

Step-by-step explanation:

2 + 15/8 = 2/1 + 15/8

Let's add 2/1 + 15/8 like this:

2/1 × 8/8 = 16/8

16/8 + 15/8 = 31/8

Since that is an improper fraction, we will simplify it.

31/8 = 3 7/8

Answer:

If this point is 0, -5, one of the points of symmetry would be a simple reverse on the y axis. It would be 0, 5.

If we are talking respect to the x axis in general, another reverse point or quadrant would be -5, 0.
