Answer:

[tex]Boys = 24[/tex]

[tex]Girls = 18[/tex]

Step-by-step explanation:

Given

[tex]G:B= 3:4[/tex]

[tex]Total = 42[/tex]

Required

Determine the number of boys and girls

We have to convert the ratio to fraction;

Number of girls can be calculated as:

[tex]Girls = \frac{G}{G + B} * Total[/tex]

[tex]Girls = \frac{3}{3 + 4} * 42[/tex]

[tex]Girls = \frac{3}{7} * 42[/tex]

[tex]Girls = 3 * 6[/tex]

[tex]Girls = 18[/tex]

[tex]Boys = Total - Girls[/tex]

[tex]Boys = 42 - 18[/tex]

[tex]Boys = 24[/tex]

Answer:  -5x^3 -13x^2 -6x + 15ix + 39ix + 18i

Step-by-step explanation:

An equation with zeros at these numbers could be put in form x = number.

So, (x-3) could be set to 0 to get x=3.

So, you can look at these "answers" they give you and work backward to get:

(x-3)(x+2/5)(x-3i)

Multiply first two together.

x^2+2/5x-3x-6/5

simplify

x^2 - 2 3/5x -6/5

Change first term to have same denominator by multiplying by "1" in the form of -5/-5

-5x^2/-5 - 13/5x -6/5

Divide all terms by 1/5 (which is the same as multiplying each term by 5)

(-5x^2 -13x -6)

Now multiply by (x-3i)

-5x^3 -13x^2 -6x + 15ix + 39ix + 18i

2. 8 x 43 = 344

8 x 43 = 8 (40 + 3)

8 x 43 = 320 + 24

3. 6 x 532 = 3192

6 x 532 = 6 (500 + 30 + 2)

6 x 532 = 3000 + 180 + 12

4. 5 x 923 = 4615

5 x 923 = 5 (900 + 20 + 3)

5 x 923 = 4500 + 100 + 15

Answer:

455.53cm^2

Step-by-step explanation:

diameter of hemisphere = 10cm

radius of hemisphere = 10/2 cm = 5cm

height of hemisphere = radius of hemisphere = 5cm

height of cylinder = 12cm - 5cm = 7cm

surface area = 2pi(5)7 + pi(5)^2 + 2pi(5)^2 = 455.53cm^2 (5sf)

Answer:

455.53cm^2

The constant of proportionality for the ratio of cubs to female bears is 3.

The constant of proportionality is typically used when we are comparing something with another thing.

In this case, since every female bear has 3 baby cubs, the constant of proportionality for the ratio of cubs to female bears will be:

= 3/1

= 3

In conclusion, the correct option is 3.

Answer:

Step-by-step explanation:

16x=-112

x=-112/16

x=-7

PLS GIVE BRAINLIEST

When you use the substitution method you need to plug a value into the corresponding variable of another equation.

In this occasion,"-6y-7" can be plugged into the x of "16x-4y=18" because it represents the x.

16(-6y-7)-4y=18

Distribute 16 into the parentheses

-96y-112-4y=18

Combine like terms

-96y-4y-112+112=18+112

-100y=130

Divide by -100 to get y by itself

y=-1.3 or -13/10

Now plug the y into any equation...I chose "x = -6y - 7​" but it doesn't matter

x= -6(-1.3)-7

x=-14.8 or 4/5

Answer:

Step-by-step explanation:

Decimal number in mathematics is one in which the whole number and the fractional part is separated by a decimal point

If we divide 4 by 10 it will give us a a decimal number which was done below

4/10

=0.4

And also if we divide 40 by 100 we will still have a decimal of 0.4

0.4=40/100

Express 4/10 as a decimal number, and identify another decimal number that is equal to it. 4/10 expressed as a decimal number is 0.4 which is equal to _40/100__

Answer: g*5 + b*10 ≥ 50.

Step-by-step explanation:

Let's define g = number of rings that land in green boxes.

and b = number of rings that land in blue boxes.

For each ring in the green box you earn 5 points, then if there are g rings in the green box, you have g*5 points.

And for the blue is similar, if there are b rings in the blue box, you will have b*10 points.

Then the total number of points that you will get is:

T = g*5 + b*10.

And the minimum that you need to win is 50 points, the inequality will be:

T ≥ 50

or

g*5 + b*10 ≥ 50.
