(121÷11)-√49
125+9×7​

Answer:

y = 10x

(x is a set of odd numbers between 11 and 99)

Step-by-step explanation:

Given;

divisor = 20

remainder, = 10

let the 3 - digits dividend = y

let the quotient = x

Arranging all in mixed fraction;

[tex]\frac{y}{20} = x\frac{10}{20} \\\\\frac{y}{20} = \frac{10x}{20} \\\\\frac{y}{20} = \frac{x}{2} \\\\2y = 20x\\\\y = 10x[/tex]

where x = 11, 13, 15, 17, 19 - - - - - - - 99

The divisor would be between 5 and 49. So I chose 38. 38x20 is 760. 760+ 10 (which is the remainder) is 770.

Therefore, The divisor would be 38 and the dividend would be 770.

Have a great day!

I hope it helps!

Answer:

3.8cm

Step-by-step explanation:

in total there are 6,4,8 which equals 18 .There are 18 balls in total. but Alex removed 3 so now there are 15 balls. There 3 different colors and 15 balls. So there is a 5% out of 15 that you will get a certain color .To find the probability you need to calculate all the possible outcomes.

G=Green   R=Red    P=Purple

G,R,P

G,P,R

P,G,R

P,R,G

R,P,G,

R,G,P

There is 6 different outcomes, 15 balls and a 5% chance to get a certain color so if you want to exactly get G,R,P there is a (15 divided by 6) chance to get that order.

(I'm not good at calculating that part.)

Answer:

101

Step-by-step explanation:

Opposite of 79 must add to 180 which is 101 and x is equivalent

Answer:

101°

Step-by-step explanation:

x + 79° = 180° ( being co-interior angles )

x = 180° - 79°

x = 101°

Answer:

62.2 inches

Step-by-step explanation:

a²+b²=c²

Plug in your known variables.

50²+37²

This will equal to 3869

Now you will have 3869 = c²

Square root both sides

√3869 = √c²

62.2 inches ≈ c

Answer:

4.07

Step-by-step explanation:

Answer:

Incase you wanna make it easier multiply both the number by 100 you'll get 1950 and 1543 now substract them you'll get 407 and then devide 407 by hundred, you don't have to devide actually you've to just shift the decimal two digits!

Answer:

3 is your base

4 is your height

(this is for the area of the bottom)

3 x 4 = 12

12 divided by 2 = 6 is your area of the bottom

6 x 4(height) = 24

24 divided by 3(times 1/3) = 8

its probably is B. I am not sure. I wouldnt trust me though but you can if you want. ._.

Answer:

true

Step-by-step explanation:

Answer:

Yes, the statement "An exponential decay function represents a quantity that has a decreasing halving time" is true. In addition, this process can be expressed by the following differential equation, where N is the quantity and λ (lambda) is a positive rate called the exponential decay constant: d N d t = − λ N . {displaystyle {frac {dN} {dt}}=-lambda N.}

answer: 92

Step-by-step explanation:

These Will add up to 360 in total so b and c our 92 because 92 + 92 + 88 + 88 = 360 Hope that helps!

Step-by-step explanation:

here's your solution

==> 88° + b° = 180°. [ linear pair ]

==> b° = 180° - 88°

==> b° = 92°

b° = c°. [ vertical angle ]

==> c° = 92°

Answer:

5 units

Step-by-step explanation:

here;

perpendicular (p)= 3

base (b) = 4

hypotenuse (h) = c= ?

By Pythagorean relationship;

h²=p²+b²

or, h= √(p²+b²)

or, c= √(3²+9²)

or, c= √25

hence, c=5

Answer:

CBD is 120 degrees

Step-by-step explanation:

x=30

4x30+30+30=180

Answer: 120°

Step-by-step explanation:

x + 4x + x = 180° (Since the sum of a straight line is 180°)

6x = 180°

x = 30°

To find the angle of 4x, we need to multiply 4 x 30°

120°

Answer: Girls: 20

Boys: 30

Step-by-step explanation: 40% of 50 is 20, which means there are 20 girls.

Subtract 50-20 to get the number of boys, which is 30.

Answer:

If you asked the correct question, the answer would be 52.5 boys.

But, I believe the correct question is "In a class of 35 students, 40% are girls. Determine the number of boys." And the answer is 21 boys.
