Hey pls help me in this thanks a lot

Answer:

Let's define the variables:

f = Cost per cake

d = Cost per drink.

"Stephen goes to the fair and buys two funnel cakes and one drink. His total bill is $6.75. "

2*f + 1*d = $6.75

"A few days later, he goes with a friend and buys three funnel cakes and two drinks. This time his total bill is $11."

3*f + 2*d = $11.

Then we have a system of equations:

2*f + 1*d = $6.75

3*f + 2*d = $11.

To solve this, the first step is to isolate one of the variables in one of the equations, let's isolate d in the first equation:

d = $6.75 - 2*f

Now we can replace this in the other equation:

3*f + 2*($6.75 - 2*f) = $11

3*f - 4*f + $13.50 = $11

-f = $11 - $13.50 = -$2.50

f = $2.50

Then the cost of a funnel cake is $2.50

And the cost of a drink can be obtained with the equation:

d = $6.75 - 2*f = $6.75 - 2*$2.50 = $1.75

The cost of a drink is $1.75

Answer:

3/10

Step-by-step explanation:

83/10 - 3/10 = 80/10 = 8

E=egg farm

x=distantce between  the Berto´s trains and the meeting point.

t=time where the trains meet up

⇒110 miles/h                                          ⇒85miles/h

[---------------------------E----------------------]-------------------------------------X

[............12 miles.......][........34 miles.....][------------ x ----------------------]

distance between Berto´s train and Eduardo´s train=

=12 miles+34 miles=46 miles.

S=d/t      ⇒d=S*t

S=seed

d=distance

T=time

Eduardo´s train;

46 miles+x=t*110 miles/h  ⇒x=t*110 miles/h-46 miles  (1)

Berto´s train;

x=t*85 miles/h  (2)

With the equations (1) and (2) we suggest this system equations:

x=t* 110 miles/h-46 miles

x=t*85 miles/h

we solve this system equiations :

t*110 miles/h-46 miles=t*85 miles/h

110t miles/h-85t miles/h=46 miles

25 t miles/h=46 miles

t=46 miles/25 miles/h=1,84 hour  (≈1 hour, 50 minutes, 24 seconds)

x=t*85 miles/h=156,4 miles

Solution: 1,84 hour

Answer:

300 shirts

Step-by-step explanation:

You can divide 12% by itself to find one percent, then divide the 36 shirts by 12 as well.

What you do to one side, you need to do to the other.

Now that we have our numbers after dividing (you should have 1% and 3 shirts) you can see what 100% would be. To do this you would multiply 1% by 100 and multiply 3 shirts by 100.

Now we know that 12% of 300 shirts is 36 shirts.

Step-by-step explanation:hn

Answer:

a) The volume of concrete needed in cubic feet is 2,112. b) The number of cubic yards of concrete needed in cubic yards is about 79. c) The cost of the concrete using cubic yards is $2,844.

Step-by-step explanation:

a) The formula of the volume is l*w*d. 24 * 11 * 8 = 264 * 8 = 2,112.

b) The way to find this is that you take 2,112 and divide it by 27. Since the answer is 78.2 repeating, you round it up to 79 so it will fill up all of the concrete.

c) Since you need 79 cubic yards of concrete, you do 79 multiplied by $36 to get the total cost of $2,844.

Given: AB≅DE, BC≅EF, CA≅FD

Since those are the given it is maped A to D, B to E, C to F

This is a rigid transformation because the distance is preserve (givens) and the triangle ABC is map to triangle DEF.

Rigid transformations produce congruent figures so triangle ABC is congruent to triangle DEF

Step-by-step explanation:

a=-4 r=12/-4=-3

T7= ar^n-1

= (-4)(-3)^7-1

=-2916

The first term of this geometric sequence is equal to: A. -2916.

Mathematically, a geometric sequence is given by this expression:

[tex]a_n =a_1r^{n-1}[/tex]

Where:

Based on the geometric sequence, the first term is equal to -4. Also, the common ratio is given by:

r = 12/-4

r = -3.

For the 7th term, we have:

a₇ = -4 × (-3)⁷⁻¹

a₇ = -4 × (-3)⁶

a₇ = -4 × 729

a₇ = -2916.

Answer:

  512 million

Step-by-step explanation:

Expected value is the sum of the products of probability and the value associated with that probability. Here, it is the sum ...

  0.4(390) +0.4(890) +0.2(0) = 512 . . . million

The expected value of the loss over a 5-year period is $512 million.

Answer:

The expected winning is + $2.17

Step-by-step explanation:

Here, we want to calculate the expected winnings for the game

The number of possible results are;

1,2,3,4,5,6

Probability of each value is 1/6

So expected pay off is as follows;

1/6(5) + 1/6(3) + 1/6(5) + 0

= 5/6 + 3/6 + 5/6

= 5/6 + 5/6 + 1/2 + 0

= 10/6 + 1/2 = 5/3 + 1/2 = (10 + 3)/6 = 13/6 = 2.1667

Answer:

I found the table by an online search (it is below)

Sally has $7 to spend in candy.

The price of a chocolate bar is $1.50

The price of a lollipop is $0.75

The price of gumballs is $0.25

In the table, we have the following combinations.

a) 3 chocolate bars, 3 lollipops and 4 gumballs, the price is:

3*$1.50 + 3*$0.75 + 4*$0.25 = $7.75 (she can not buy this)

b) 3 chocolate bars and 4 gumballs, the price is:

3*$1.50 + 4*$0.25 = $5.50 (she can buy this)

c) 1 chocolate bar, 5 lollipops and 2 gumballs, the price is:

1*$1.50 + 5*$0.75 + 2*$0.25 =  $5.75 (she can buy this)

d) 2 chocolate bars, 2 lollipops and 8 gumballs, the price is:

2*$1.50 + 2*$0.75 + 8*$0.25 = $6.50 (she can buy this)
