Answer:

36

Step-by-step explanation:

So to find the answer we know that the ratio is 4:3:3 if colin gets 48 the ration will be 48:?:?

We have to find the ?

to find the ? we need to divide 48 with 4 and we get 12

now we know that it is 12 we have to multiply all of it with 12 to find Gordon and Sara

So 3 x 12 = 36

So the new Ratio is 48:36:36

Gardon is at the end and the number at the end is 36

So we now know the answer

Answer:

36

Step-by-step explanation:

Colin : Sara : Gordon = 4 :  3: 3

Colin's share = 4x

Sara's share  = 3x

Gordon's share = 3x

Colin's share = 48

              4x =  48      {Divide both sides by 4}

                x = 48/4

               x = 12

Gordon's share = 3x = 3*12 = 36

0,-2

4,4

2,0

3,5

Step-by-step explanation:

that was my answer

In this triangle it is given that one angle if of 30⁰ and another one is of 90⁰

so By using ANGLE SUM PROPERTY we can solve it

so,

30⁰+ 90⁰ + 4x - 4⁰ = 180⁰(ASP)

120⁰ + 4x - 4 = 180⁰

4x - 4 = 60⁰

4x = 64

x = 16⁰

Hence solved

Answer:

There are 25 yellow flowers.

Step-by-step explanation:

The ratio is yellow/all and 5/9.

We know that all the flowers in total equal 45, which is a multiple of 9.

So 45 divided by 9 = 5.

So all I had to do was multiply 5/9 times 5/5.

So then we get the ratio of 45 total flowers with 25 yellow flowers.

Answer:

81 feet ²

Step-by-step explanation:

Given that:

Dimension of rectangular prism :

6 feets by 2.5 feets by 3 feets

To obtain the amount of wrapping paper required to cover the box ; we find the area of the box ;

Area of box = 2(wl + hl + hw)

Area of box = 2(6*2.5 + 6*3 + 2.5*3)

Area of box = 2(15 + 18 + 7.5)

Area of box = 81 feet²

Answer:

missing angle = 41, b. 45, c. 72

Step-by-step explanation:

A circle has 360 degrees, so add all of the existing angles

48+45+129+97 = 319 and 360-319 = 41

25/200 = 12.5% so 12.5% of 360 = .125x360 = 45

Sector 129 represents 129/360 = 35.83% so 200x.3583=72 cars

Answer:

your answer is point g and h

Answer:

58°

Step-by-step explanation:

Start with the equation 2x + 2 + 90 = 148

( I got the 90 from Angle B since it is a right angle.)

Combine like terms 2x + 92 = 148

( 90 and 2 didn't have variables so you could add them together.)

Subtract 92 from both sides 2x + 92 = 148

                                                      -92   -92

(The opposite of addition is subtraction.)

Now write out the new equation 2x = 56

Divide both sides by 2 [tex]\frac{2x}{2}[/tex] = [tex]\frac{56}{2}[/tex]

You'll end up with... x = 28

To find the measure of angle BAC, plug in 28 where the x value is 2(28) + 2

This gives you the answer 58°

Step-by-step explanation:

Number of biking outfit Makayla buy is 7

Given:

Total amount spend by Makayla = $740

Cost of bicycle = $465.34

Cost of 4 bicycle reflectors = $13.25(each)

Cost of pair gloves = $18.12

Cost of each biking outfit = $25.69 each

Find:

Number of biking outfit Makayla buy

Computation:

Assume;

Number of biking outfit Makayla buy = a

Total cost = Cost of bicycle + Total Cost of 4 bicycle reflectors + Cost of pair gloves + Total cost of biking outfit

465.34 + 4(13.25) + 18.12 + a(25.69) = 740

465.34 + 53 + 18.12 + a(25.69) = 740

536.46 + a(25.69) = 740

a(25.69) = 740 - 536.46

a(25.69) = 203.54

a = 7.9229

Rounding number to less

So.

Number of biking outfit Makayla buy = 7 (Approx.)
