Number of combinations

= 5C2 * 7C3

= 10 * 35

= 350.

Hence there are 350 possible ways.

P.S.

5C2 = 5! / (2!3!) = 120 / (2 * 6) = 10.

7C3 = 7! / (3!4!) = 5040 / (6 * 24) = 35.

Answer : A) 15

138+132=270

270÷18=15

That’s why the correct answer is 15.

Answer:

3/4 bucket

Step-by-step explanation:

Given that:

1/2 bucket of nut fills 2/3 of barrel ;

Letbthe number of bucket if nut which fills entire barrel = x

Fraction of entire barrel = 1 /1 = 1

1/2 bucket = 2/3 barrel

x buckets = 1 barrel

Cross multiply ;

(2/3)x = 1/2

2x / 3 = 1/2

2x * 2 = 3 * 1

4x = 3

x = 3/4

Hence, 3/4 bucket of nut will fill entire barrel

Answer:  19.5 GB

To find this answer, we multiply the number of daughters (3) by the amount of data each uses per month (6.5)

So, 6.5*3 = 19.5 is the total amount of gigabytes used per month.

Answer:

The percent of increase in the size of the sugar order is 75%.

Step-by-step explanation:

To find the percent of increase in the size of the sugar order, you can use the following formula:

% increase = ((New number-Original number) ÷ Original Number)x100

New number=13,510

Original number=7,720

Now, you can replace the values in the formula:

% increase = ((13,510-7,720) ÷ 7,720)x100

% increase = (5,790 ÷ 7,720)x100

% increase = 0.75x100

% increase = 75%

According to this, the answer is that the percent of increase in the size of the sugar order is 75%.

Answer:

$3

Step-by-step explanation:

Given :

Let game 1 = x ; game 2 = y

4x + 6y = 18 - - - (1)

5x + 5y = 20 - - - (2)

From (2)

x + y = 4

y = 4 - x

Substitute y = 4-x in (1)

4x + 6(4 - x) = 18

4x + 24 - 6x = 18

-2x = 18 - 24

-2x = - 6

x = 6/2

x = 3

Game 1 cost $3

Answer:

The first swing is 64m

Step-by-step explanation:

The complete question asks for how long the first swing is.

The monkey is swinging from the tree with each swing being along an arc, where each arc is 75% of the previous arc. Also, given that its first four swings is 175cm, we can denote her first swing as y.

This means the second swing would be = 0.75y

The third would be = 0.75(0.75y) = 0.5625y

The fourth would be = 0.75(0.5625y) = 0.421875y

Since the total is 175, we have

y + 0.75y + 0.5625y + 0.421875y = 175

2.734375y = 175

y = 175/2.734375

y = 64m

Answer:

$1,006.25

Step-by-step explanation:

If you sell 70 adult tickets at $12.50 each, use the equation

12.5*70=875

By using the same equation for kids tickets,

8.75*15=131.25

Then add the sums

875+131.25=1006.25

Hope this helps!

Answer:

We want to prove the relation:

cosec(a)^2 - cot(a)^2 = 1

where:

cosec(a) = 1/sin(a)

cot(a) = 1/tg(a) = cos(a)/sin(a)

We can start with the relationship:

cos(a)^2 + sin(a)^2 = 1

Now, let's divide by sin(a)^2 in both sides:

(cos(a)^2 + sin(a)^2)/sin(a)^2 = 1/sin(a)^2

cos(a)^2/sin(a)^2 + sin(a)^2/sin(a)^2 = (1/sin(a))^2

(cos(a)/sin(a))^2 + 1 = (1/sin(a))^2

and remember that:

cosec(a) = 1/sin(a)

cot(a) = 1/tg(a) = cos(a)/sin(a)

Then we can write:

(cos(a)/sin(a))^2 + 1 = (1/sin(a))^2

as:

cot(a)^2 + 1 = cosec(a)^2

1 = cosec(a)^2 - cot(a)^2

And this is the relation we wanted to prove.

Answer:

alright hers your brainliest and thank you very much i  really appreciate it

Step-by-step explanation:

Answer:

m<1 51°

m<2 34°

m<3 95°

m<4 38°

m<5 47°

m<6 74°

m<7 59°

m<1 there are 180° on a straight line. 180-129= 51°

m<2 there are 180° in a triangle. we have been given 95° and have just established that m<1 is 51° 180- 95- 51 = 34°

m<3 is a vertically opposite angle to the 95° given. therefore must = 95°

m<4 180° in a triangle. have just established m<3 as 95° have been given 47°. 180 - 95 - 47 = 38°

m<5 is vertically opposite to the 47° given so therefore = 47°

m<7 180° on a straight line 180 - 121 = 59°

m<6 180° in a triangle have previously established that m<5 = 47° and m<7 = 59°

180 - 47 - 59 = 74°
