please help i really need it

Answer:

1.  10√3

2. -√5

3. 21√3 -9√5

4. 12√7-√11

5. 8√5-3(√5*√4) = 8√5- (3*2)√5= 2√5

6. √5*√4 -√5= 2√5-√5= √5

7. 3√5*√9 +√5*√4 -√49*√5 = 15√5+2√5-7√5= 10√5

8. √6*√4 - √6*√9 + √16*√6= 2√6-3√6+4√6= 3√6

Hope it helps you :)

Answer:

120

Step-by-step explanation:

The number of friends is 5 and there are 5 seats only. So , we can find it out with the help of permutations ,

[tex]\implies ^n P_r = \dfrac{n! }{(n-r)!} [/tex]

⇒ 5! / (5-5)!

⇒ 5! / 1!

⇒ 5!

⇒ 5 × 4 × 3 × 2 × 1

⇒ 120

Answer:

x = 14

Step-by-step explanation:

two negatives become a positive so the equation is now

x + 3 = 17

subtract 3 from both sides, giving you 14

Answer:

False

Kilometer

Step-by-step explanation:

First Question:

1 km = 1000 m

2 km = 2 * 1 km = 2 * 1000 m = 2000 m

Centennial Park is 2 km = 2,000 m away.

Canatara Park is 2,548 meters away.

Since 2,548 > 2,000, Canatara Park is farther away than Centennial Park.

Answer: False

Answer: £80

Step-by-step explanation:

First, we need to calculate the number of gallons used by Sally. This will be:

= 560 / 34.5

= 16.23 gallons

Since 1 gallon = 4.55 litres, we calculate the number of liters and this will be:

= 16.23 × 4.55

= 73.85 liters

Since Petrol cost £1.08 per litre, the cost of the petrol will be:

= £1.08 × 73.85

= ££79.758

= £80 approximately

Answer:

y = a 2 d x + k y=a2^{dx}+k y=a2dx+k

Step-by-step explanation:

Determine the exponential function in the form y = a 2 d x + k y=a2^{dx}+k y=a2dx+k of the given graph. To solve this problem, we're going to need to find the variables "a", "d", and "k". Remember, we can find "k" from the graph, as it is the horizontal asymptote.

The 34th term of the sequence is 172

This is a type of sequence which have a common difference (d) between each term

From the question given above, the following data were:

The 34th term of the sequence is 172

Given the sequence 7, 12, 17...

The nth term of the sequence is expressed as;

Given the following

a = 7

d = 12 - 7 = 5

n = 34

Substitute the given parameters

T34 = 7 + (34 - 1)*5

T34 = 7 + (33)*5

Answer:

[tex]N_t=6.455\ yards[/tex]

Step-by-step explanation:

From the question we are told that:

Total String [tex]N=71/2[/tex]

Strip size [tex]N_s=11/2[/tex]

Generally the equation for Total Number of strip cut [tex]N_t[/tex] is mathematically given by

[tex]N_t=\frac{N}{N_s}[/tex]

Therefore the  strips of string can she cut with 7 1/2 yards is Given as

[tex]N_t=\frac{71/2}{11/2}[/tex]

[tex]N_t=\frac{71}{2}*\frac{2}{11}[/tex]

[tex]N_t=\frac{71}{11}[/tex]

[tex]N_t=6.455\ yards[/tex]

Answer:

Answer:

y = (2/3)x + 3

Step-by-step explanation:

Notice that if we start at any x value shown in the table and increase x by 3, y will increase by 2.  Thus, the slope of the line is 2/3.  

From the entry (0, 3), we know that the y-intercept is b = 3.

Thus, y = mx + b becomes:

y = (2/3)x + 3

Answer:

5 cm

Step-by-step explanation:

Arc length (S) = 10 cm

Answer:

3 hours and 50 minutes

Step-by-step explanation:

Given that

Sarah drives for 1 hours and 40 minutes

And, rest for 25 minutes

And, then drive for another 1 hour & 45 minutes

We need to find out the total travel time in hours and minutes

First we convert into minutes i.e.

= 1 hour + 40 minutes + 25 minutes + 1 hours + 45 minutes

= 60 minutes + 40 minutes + 25 minutes + 60 minutes + 45 minutes

= 230 minutes

i.e.

3 hours and 50 minutes
