Answer:

$6.40

Step-by-step explanation:

13 + 12 + 10 = 35

28 / 35 = 0.8

0.8 * 12 = 9.6

9.6 * 2/3 = 6.4

The money Tammy has now if Sally is 13 years old. Tammy is 12 years old. Danny is 10 years old. Sally, Tammy, and Danny share £28 in the ratio of their ages. Tammy gives a third of her share to her mother is $4.57.

It is the contrast of two different quantities. For instance, if your father weighs 90 kg, and you weigh 30 kg, the weight ratio is 1:3.

Given:

The age of Sally = 13 years,

The age of Tammy = 12 years,

The age of Danny = 10 years,

Then according to the question

13x + 12x + 10x = 28

35x = 28

x = 4 / 7

One-third of Tammy's money = 12 × 4 / 7 ×1 / 3 = 2.285

Money left  = 48 / 7 - 2.285 = 4.57

Therefore, the money Tammy has now, if Sally is 13 years old. Tammy is 12 years old. Danny is 10 years old. Sally, Tammy, and Danny share £28 in the ratio of their ages. Tammy gives a third of her share to her mother is $4.57.

Answer:

We get that √48 = 2⋅2√3. Lastly, step three says to simplify, so we go ahead and multiply the 2⋅2 outside of the square root to get 4√3. That's it! We get that √48 = 4√3.

Step-by-step explanation:

Answer:

The correct answer is √48 = 4√3.

Answer:

x = 105

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 7, thus

sum = 180° × 5 = 900°

Sum the interior angles and equate to 900

x + 102 + 165 + 123 + x + 11 + 128 + 161 = 900, that is

2x + 690 = 900  ( subtract 690 from both sides )

2x = 210 ( divide both sides by 2 )

x = 105

Step-by-step explanation:

Answer:

√[(2*2)*(4*6)]

= 4 √6

Step-by-step explanation:

√96.

Sometimes it is better to ‘simplify’ by getting a coefficient multiplied by a smaller number within the radical. Other times, you’re really not simplifying, but making it more complicated. This is probably one of those times where leaving it as √96 is better.

If you had something like √196, you would want to change that form since it turns out that 196 is a perfect square.

Regardless, I’m assuming this is a problem for a class and your teacher/text book wants you to do the following……

You could start by factoring it in small steps within the radical sign.

If you find factors that are perfect squares, you can take them out of the radical.

You can find large factors if you want, but you can also start with small factors.

Probably the easiest number to factor out is 2 since 96 is an even number.

96/2 = 48.

square root 96 radical form

48 is also an even number, so you can factor another 2.

Now you have √[(2*2)*24]

If you can factor out larger numbers, it can save you a little time.

So from here let’s factor out a 4.

√[(2*2)*(4*6)]

= 4 √6

Answer:

Step-by-step explanation:

Using the given data we can have the equation below to the time:

x = 0 and x = 4

To find intersection equate them.

x² - 2x - 4 = 2x - 4

subtract 2x - 4 from both sides

x² - 4x = 0 → (take out common factor x)

x(x - 4 ) = 0 ⇒ x = 0 , x = 4

Answer:

x=28

Answer:

Whats the problem?

Step-by-step explanation:

Answer:

Answer is a = -4

3a + 4 = 2a

Subtract 2a from each side

a + 4 = 0

Subtract 4 from each side

a = -4

Step-by-step explanation:

Answer:

a = 1/3g+4/3

Step-by-step explanation:

g=3a−4

Step 1: Flip the equation.

3a−4=g

Step 2: Add 4 to both sides.

3a−4+4=g+4

3a=g+4

Step 3: Divide both sides by 3.

3a /3 = g+4 3

a =  1 /3 g+ 4 /3

Answer:

a) 9 miles/hour

b) 17.5 miles/hour

Step-by-step explanation:

The formula for speed = Distance (Miles) / Time(hours)

a) he can travel 3/4 of a mile in 5 minutes.

= 3/4 miles = 5 minutes

We convert 5 minutes to hour

= 60 minutes = 1 hour

5 minutes = x

Cross Multiply

60x = 5

x = 5/60

x = 1/12 hour

Hence, his skate speed =

3/4miles /1/12 hour

= 3/4 ÷ 1/12

= 3/4 × 12/1

= 9 miles/hour

b) On his bike, he can travel 3 1/2 miles in 12 minutes.

= 3 1/2 = 12 minutes

= 7/2 miles = 12 minutes

We convert 12 minutes to hour

= 60 minutes = 1 hour

12 minutes = x

Cross Multiply

60x = 12

x = 12/60

x = 1/5 hour

Hence, his skate speed =

7/2 miles /1/5 hour

= 7/2 ÷ 1/5

= 7/2 × 5

= 35/2 miles/hour

= 17.5 miles/hour
