Answer:

  2 colas and 4 hot dogs

Step-by-step explanation:

We presume the units of total satisfaction are additive for the two food items.

The maximum number of colas Joe can buy with his $8 is $8/($2/cola) = 4 colas. Since a cola costs twice what a hot dog costs, Joe can give up 1 cola and buy 2 hot dogs. Possible purchases of (colas, hotdogs) for $8 can be ...

 (0, 8), (1, 6), (2, 4), (3, 2), (4, 0)

Of course, either the number of colas or the number of hot dogs (or both) could be less than these values.

The corresponding satisfaction units are added in the attached table. These combinations are highlighted in green. The maximum number of satisfaction units is found to be for 2 colas and 4 hot dogs. (49 satisfaction units)

_____

Satisfaction values below and to the right of the highlighted diagonal cannot be purchased with $8.

An older automobile has a fan belt assembly that is the shape of an isosceles triangle. The two equal sides are 12.0 inches each, and the third side is 9.0 inches. An older truck has a similar fan belt arrangement, but we isosceles triangle has Width 18.0 inches. What is the length, in inches, of the two equal sides of the triangle?

Answers

Answer:

  24 inches each

Step-by-step explanation:

The base of the triangle in the truck is 2 times that in the automobile, hence the similar triangle will have sides that are 2 times 12.0 inches each.

The two equal sides of the truck triangle are 24.00 inches each.

explain what is meant by the given formula:
a1=12
an=an-1-8

Answers

Step-by-step explanation:

that this is an arithmetic sequence of terms, where every term is created by adding (or subtracting) to/ from the previous term.

a1 is the starting value = 12

then

a2 = a1 - 8 = 12 - 8 = 4

a3 = a2 - 8 = a1 - 8 - 8 = -4

every term is 8 less than the previous term.

so, we see, we can express the nth term of the sequence also in terms of a1 :

an = an-1 - 8 = a1 + -8×(n-1) = a1 - 8×(n-1)

Answer:

y = 6/8x - 3/2

Step-by-step explanation:

In this case, since we don't yet know the exact fraction for the y-intercept, we will find the slope first.

To find slope, we will simply start at the first point that is given to us on the graph, and then count the units up and over until we reach the second point. (Remember rise/run)

Our slope is 6/8, because we went upwards 6 units and to the right 8 units.

Now, in order to find the y-Intercept, we will use the point slope formula⤵⤵⤵

[tex]y - y _{1} = m(x - x _{1})[/tex]

We will plug in one of the points that the line passes through. In this case we will use the first given point. The coordinates of the point are (-3,-2).

y - (-3) = 6/8 (x- (-2)) or we can just simplify this to:

y + 3 = 6/8 (x + 2)

To solve this, first distribute 6/8 among everything inside the parenthesis to get

y + 3 = 6/8x + 3/2 (6/8 × 2 = 12/8 then simplify to 3/2). Next we will subtract 3 on both sides to get

y = 6/8x - 3/2.

And there we go, we're done. Hope this helps you :)

Answer:

x=16

Step-by-step explanation:

Equations which are never true:

4.1      Solve :    -2   =  0

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

4.2      Solve  :    x+16 = 0

Subtract  16  from both sides of the equation :

                     x = -16

One solution was found :

x = -16

Step-by-step explanation:

First distribute: -2x - 28 + 1 = 5

Now simplify: -2x - 27 = 5

Now addition property of equality: -2x = 5 + 27

Now simplify: -2x = 32

Now division property of equality: x = 32/-2

Simplify: x = -16

If you need it as a fraction then you can put - [tex]\frac{16}{1} \\[/tex]

_________

x < -5

On the number line, the values of x are on the left side of -5 where -5 is not included and this can be determined by simplifying the given inequality.

Given :

Inequality  --  (x + 3 < -2)

The following steps can be used to graph the solution of the given inequality:

Step 1 - Write the given inequality.

x + 3 < -2

Step 2 - First, simplify the given inequality. Subtract 3 on both sides in the above inequality.

x + 3 - 3 < -2 - 3

x < -5

Step 3 - So, the interval of x is given by ([tex]-\infty[/tex], -5).

Step 4 - On the number line, the values of x are on the left side of -5 where -5 is not included.

In a pack of starbursts, 25% of the
pieces were pink. If there were 12
pieces that weren't pink - how many
pieces were in the entire package?
How many pieces were red?

Answers

Answer: 16 total starbursts.

Step-by-step explanation:

If 25% were pink, then 75% aren't pink.  Let x be the total number of starbursts.  We know that 75% of x = 12 (the ones that aren't pink).  There is insufficient information to determine whether there is even one red starburst.

0.75x = 12

x = 12/(3/4)

x = 48/3

x = 16

There are 16 total starbursts:

25% are pink = 4 pink starbursts

75% aren't pink = 12 non pink starbursts

Total of 16 starbursts.

We can't answer how many were red.  We aren't given any indication that there is even one red starburst.  All we know is that 12 are not pink.

A transportation rental company charges $11.50 for a bicycle rental, plus an additional $2.50 per hour that the bicycle is rented. Partial hour rentals are allowed. The total charge for a certain rental is $20.25. How long was the bicycle rented? Enter your answer in the box.

Answers

Answer:

3 hours 30 minutes

Step-by-step explanation:

First hour,

All cost, $11.50+$2.50 =$14

remaining charge, $20.25-$14 =$6.25

partial hour,

$2.50 ÷ 2 = $1.25

remaining hour,

per hour, $6.25 ÷ $2.50 = 2.5 hours

total hour rented,

1+2.5 = 3.5 hours

or

0.5 × 60 minutes = 30 minutes

3 hours 30 minutes

3.5 hours was the bicycle rented.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

Transportation rental company charges $11.50 for a bicycle rental, plus an additional $2.50 per hour that the bicycle is rented

11.50+2.50x

Partial hour rentals are allowed

The total charge for a certain rental is $20.25.

All cost, $11.50+$2.50 =$14

remaining charge, $20.25-$14 =$6.25

partial hour,

$2.50 ÷ 2 = $1.25

Remaining hour,

per hour, $6.25/$2.50 = 2.5 hours

Total hour rented, 1+2.5 = 3.5 hours

Hence, 3.5 hours was the bicycle rented.

When we subtract 90° from both sides of this equation, we find ...

  x + a = 90° . . . . . . . . the acute angles are complementary.
