Step-by-step explanation:

Answer:

9 women for every 3 men

Written as: 9:3

Can be simplified to 3:1  (9:3/3)

3 women to 1 man

Answer:

m=2/3

Step-by-step explanation:

the equation for slope (m) is (y2-y1)/(x2-x1)

here are the given points: (8,0) and (2,-4)

label the points

x1=8

y1=0

x2=2

y2=-4

substitute into the equation

m=(-4-0)/(2-8)

m=-4/-6

m=2/3

the slope is 2/3

Answer:

So if 60% of the 100% they have hopes to acheive is done, 40% of the remaining funds are left to achevie. I know, such questions are so simplistic you wonder if they are tricking you

Answer:

  5n -3

Step-by-step explanation:

Try n=1 in each expression and see which gives you a first term of 2.

  2-5n = 2-5·1 = -3

  2n -5 = 2·1 -5 = -3

  5n -3 = 5·1 -3 = 2 . . . . . this is the expression you want

  5n +2 = 5·1 +2 = 7

Additional comment

For a common difference of 5, the coefficient of n must be 5. The second answer choice fails on that count also.

Answer:

Hence the daughter's present age is 15 years

The fathers present age is 35 years

Step-by-step explanation:

Let the present age of daughter be x

Let the present age of father be y

5 years ago;

Daughter's age = x - 5

Fathers age = y - 5

If the present age of father is thrice as old as the age of daughter 5 years ago, then;

y - 5 = 3(x-5)

y - 5 = 3x-15

y = 3x - 10 .... 1

In 5 years time;

Daughters age = x + 5

Fathers age = y + 5

If the age of father will be twice the age of his daughter in 5 years time then;

y+5 = 2(x+5)

y+5 = 2x + 10

y = 2x + 5 .....2

Equate 1 and 2;

3x - 10 = 2x + 5

3x - 2x = 5 + 10

x = 15

Since y = 2x + 5

y = 2(15) + 5

y = 35

Hence the daughter's present age is 15 years

The fathers present age is 35 years

Answer:  A. 2 17 /21

Step-by-step explanation:you divide them.You change both mixed number to improper fraction.which is 236  /9  divide  28 /3.You do kcf which stand for KEEP CHANGE FLIP.YOU KEEP 236/9 and change Divide to mulipction sign and flip 28/3 to 3/28.You multiply236  /9  and  28/3 which gives u 708  /252.After that u simply it to 59 /21 .Lastly change back to mix number which is 2 17/21.

Hope it helps bye ;)

Answer: Nine I think

Step-by-step explanation: maybe because 3x3 would equal 9 and 9x1 equals 9

Answer:

$2.45

Step-by-step explanation:

First, we find how much 20% of 12.25 is:

we can convert 20% directly to a decimal:

20% = 0.2  

Then we find

20% of 12.25 = 0.2 x 12.25 = 2.45

So Maria's tip would be $2.45

Answer:

Step-by-step explanation:

we have a triangle, one leg is 40, one leg is 30

c^2=40^2+30^2

c^2=1600+900=2500

c=[tex]\sqrt{2500}[/tex]=50

Answer:

the little box would indicate that it is a 90 degree angle.

Answer: 50

Step-by-step explanation: to find CXF all you need to do is 90-40

Answer:

12

Explanation:

21 ÷ 7 × 4

21 ÷ 7 = 3

3 * 4 = 12

Answer:

12

Step-by-step explanation:

So..... multiplication can be done at the same time as division, so we don't have to worry about the order of operations :)

so, 21 divided by 7 is 3

then, you multiply 3 by 4, which is 12

and btw, I also found another methoddddddddddddd

you can do, 21 times 4, which is 84, divided by 4 times 7, which is 28

84 divided by 28 is 3

then you multiply it by 4, it gives 12

and btw, that also works for other numbers too!!!!!!!!!!!!

Answer:

√x=√25.......x=5

Step-by-step explanation:

√25-5=0

Answer:

√x-5=0

√x=5

squaring both side

√x²=5²

x=±25

Answer: 45 cups of flower

Step-by-step explanation:

Hi, you can use a proportion to solve this problem, so you start of by setting up the proportion:

Step-by-step explanation:

To start, create a ratio for flour to chocolate chips

flour : chocolate chips

5 cups : 3 cups

5:3

Now create a ratio with x amount of flour to 27 cups of chocolate chips

x cups of flour: 27 cups of chocolate chips

x: 27

Rewrite the ratios as fractions equivalent to each other

[tex]\frac{5}{3}[/tex] = [tex]\frac{x}{27}[/tex]

Cross multiply

5(27) = 3x

135 = 3x

135/3 = 3x/3

45 = x

45 cups of four would be needed

I hope this helps!!!!!

Answer:

Step-by-step explanation:

You need to make a shape that is the same shape and size to the triangle on the page.

Step-by-step explanation:

Angle ACO = 140° - x. (Sum of angles in a triangle is 180°)

Now draw the line OD. The triangles ODC and OBC are congruent via the SSS congruence property. (OD and OB are both the radius of semicircle, common side OC, and side CD = CB is given)

Hence Angle BCO = Angle ACO = 140° - x.

Since triangle OBC is an isosceles triangle with OC = OB, this means that Angle CBO is also 140° - x.

By Exterior Angle theorem,

we have Angle AOC = Angles BCO + CBO

=> x = (140° - x) + (140° - x)

=> 3x = 280°

=> x = 280°/3. (B)

Answer: I do not know

Step-by-step explanation:

I dropped out of 2nd grade

Answer:

x = 42 degrees

y = 14 degrees

Step-by-step explanation:

Solve for x

180 - 96 = 2x

2x = 84

x = 84/2

x = 42

Solve for y

180 - 94 - 44 = 3y

3y = 42

y = 42/3

y = 14

Answer: Same Side Interior Angles

Step-by-step explanation:

Imma help you eliminate the options.

-These angles are inside the parallel lines, meaning that they have to be interior angles. That eliminates any answers involving exterior angles. Next, simply by definition, it wouldn't be corresponding. Finally, alternate interior angles is eliminated because the angles are on the SAME SIDE of the transversal, meaning that Same-Side interior angles is the answer.

Answer:

No it is not a solution

Step-by-step explanation:

Key skills needed - One variable equations

1) We look at the equation, y = 4x+ 1, and see the scholar's work.

2) The scholar did everything correctly, and at the end got 9 = 13.

3) This statement is FALSE, so it would be the 2nd option (No it is not a solution)

Hope this helps and have a nice day!! :D

Answer:

its x>-249

Step-by-step explanation:

this should be the answer cause x is 0 on the line and the 249 is negative so its much less than 0

Answer:

x = 9

Step-by-step explanation:

50+80+(6x-4)=180 (ANGLE SUM PROPERTY)

130 +(6x-4)=180

6x-4=180-130

6x-4=50

6x=50+4

x=54/6

x = 9
