Answer:

The Reach for a Dream Foundation received R33000, NSPCA received R44000, and Smile received R55000.

Step-by-step explanation:

Total money for charity = R132,000

Ratio:

3 : 4 : 5

Charities:

The Reach for a Dream Foundation : NSPCA : Smile

x : y : z

3x + 4y + 5z = R132000

Charity 1 = Charity 2 = Charity 3

x = y = z

3x + 4x + 5x = R132000

x = 11000

The Reach for a Dream Foundation:

3(11000) = R33000

NSPCA:

4(11000) = R44000

Smile:

5(11000) = R55000

Double Check:

R33000 + R44000 + R55000 = R132000

Step-by-step explanation:

did the math

Answer:

Step-by-step explanation:

A line is expressed as y=mx+b where m=slope and b=y intercept. As long as we have two points we can solve the equation of that line.

y=mx+b

For the top line I found two points (5,200) and (30,325)

m=(y2-y1)/(x2-x1)=(325-200)/(30-5)=125/25=5

y=5x+b, using point (5,200) we can solve for b

200=5(5)+b, b=200-25=175 so the line is

y=5x+175

For the bottom line we have points (5,50) and 10,100)

m=(100-50)/(10-5)=50/5=10

y=10x+b, using point (5,50) we have

50=10(5)+b, b=50-50=0 so

y=10x

Answer:80 liters of petrol

Answer:

b=8

Step-by-step explanation:

Perpendicular lines are negative and reciprocal; when you multiply the slopes together, the result is -1.

we are given the line y=-3x-5

we need to find the slope of the new line. To do that, we can use this equation:

-3m=-1

divide by -3 on both sides

m=1/3

so the slope of the perpendicular line is 1/3

We can write our line in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept, which is what we need

so far our equation is:

y=1/3x+b

we need to find b

we can substitute the point (-3,7) into the equation, since the line will pass through it to solve for b

so:

7=1/3(-3)+b

7=-1+b

8=b

so the y intercept of the line is 8; as a point it's (0,8)

hope this helps!

Answer:

x = 14°

Step-by-step explanation:

We can see that these angles are supplementary.

Set up an equation

x + 96 + 5x = 180

6x + 96 = 180

subtract 96 from both sides

6x = 84

x = 14

Thus, we have our answer

Answer:

2 5/6 ft

Step-by-step explanation:

Paul perimeter = 4 1/2+6+3 1/3+3 1/3+6 = 23 1/6 ft

Ian perimeter = 2(8+5) = 26 ft

26-23 1/6 = 2 5/6 ft

Answer:

C.

Step-by-step explanation:

F(n) = 2.4 N-1

Answer:

x=11°

<Bec = 33°

<Ced = 39°

Step-by-step explanation:

That's a right angle so it would be 90 degrees angle.

18+3x+4x-5=90

Lets simplify it to make it easier to work out by collecting like terms.

First all the variable 3x+4x=7x

Then the numbers 18+-5=13

13(-13)+7x = 90(-13)take away 13 from both sides

(Opposite operators EG, Add becomes subtract)

7x = 77 then divide 7 from both sides

x=11

Then work out

3x11=33 degrees

4x11=44-5=39 degrees

To double check 39+33+18=90 degrees

Answer:

$32.1

Step-by-step explanation:

First find out what 25% of 40 is:

$40 x .25 = $10

Take the answer and subtract that from the original price:

$40 - $10 = $30

Next, take the sales tax (7% or 0.07) and multiply that by the new price:

$30 x 0.07 = $2.1

Lastly, take the answer and add that to the new price:

$30 + $2.1 = $32.1

Then you would get your answer:

$32.1

Answer:

So the answer is 2^-3

Step-by-step explanation:

The principle is the same no matter what the base.

Log_2 (7) + Log_2(3/28) - Log_2(6)

+ means multiply

- means divide

Log_2(7 * 3/28 /6)

Log_2(7/6 * 3/28)

Log_2(1/2 * 1/4)              3 divides into 6 twice. 7 divides into 28 four times

log_2 (1/8)

This is equivalent to 2^(-3)

Answer:101

Step-by-step explanation:

THis is the answer for ur question

Answer:

1) volume = 102.92 m²

2a) Perimeter = 28 inches

2b) Actual perimeter = 672 inches or 56 feet

2c) Exactly 24 times greater

Step-by-step explanation:

1)

4x5.5 = 22

full circle = (5.5²)(π) = 95

(30/360)(95) = 7.92

95+7.92 = 102.92 m²

2a)

Perimeter = (2)(6+8) = 28 inches

2b)

Actual perimeter = (2)(144+192) = 672 inches or 56 feet

2c)

(24)(28) = (2)(144+192)

672 = 672

Exactly 24 times greater

Answer:

18.6inches

Step-by-step explanation:

Given the length of a side of a pentagon to be 6 inches.

If this length is dilated by a factor of 3.1, the new length will be;

New length = Old length * dilation factor

New length = 6 * 3.1

New length = 18.6inches

Hence the length of each side of the dilated pentagon is 18.6inches
