The student council sold two types of ice cream, sundaes and cones, during homecoming week. Each sundaes cost the same amount, and each cones cost the same amount.

One the first day they earned $210 for selling 125 cones and 10 sundaes

One the second day they earned $256 for selling 100 cones and 30 sundaes.

What was the cost in dollars for each cone sold by the student council?

Answers

Answer 1

Answer:

1 cone = $1.36

Step-by-step explanation:

125 c + 10 s = $210

100 c + 30 s = $256

make one of the terms the same (easier one = 30 sundaes)

125 × 3 = 375 c

10 × 3 = 30 s

210 × 3 = $630

375 c + 30 s = $630

375 c + 30 s = $630

100 c + 30 s = $256

same sign = subtract

375 - 100 = 275 c

30 - 30 = 0 s

630 - 256 = $374

275 c = $374

÷ 275 on both sides to get c

c = $1.36

Equation of line having passing points (-6,0) and (0,-24) is 4x + y + 24 = 0

What do you mean by equation of line?

The general equation for every straight line is y = mx + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y-axis).

The variables x and y are related to coordinates on the line in the linear equation y = mx + c.

The formula y = mx + c yields a result for y when we enter a value for x.

As y depends on the value of x, it follows that x is an independent variable and y is a dependent variable.

Two passing points of line are (-6,0) and (0,-24)

Equation of line having two passing points as (a,b) and (c,d) is

[tex](y-b) = \frac{d-b}{c-a} (x-a)[/tex]

So, here equation of line become ,

[tex](y - 0) = \frac{-24-0}{0+6}(x+6)[/tex]

⇒ [tex]y = \frac{-24}{6}(x+6)[/tex]

⇒ y = -4(x+6)

⇒ y = -4x - 24

⇒ 4x + y + 24 =0

Hence, equation of line having passing points (-6,0) and (0,-24) is 4x + y + 24 = 0

Cassandra has a tangler panto in her backyard the panto is 12.74 m long and 5.45 m wide round the length and width to the nearest whole number then estimate the perimeter of cassandra is panto write an equation to show your work

Answers

The perimeter measures around 36 metre.

Describe a perimeter?

The perimeter refers to the area surrounding an object. For instance, your house has a fenced-in yard. The perimeter is the length of the fence. If the yard is 50 feet by 50 feet, your fence is 200 feet long.

While 12.74 rounds up to 13, 5.45 rounds down to 5. Recatangle created a total of four sides, two of which are identical in length to the other two (which is a poor way to explain it). There are two sides that are 13 inches long and two sides that are 5 inches long, which is the solution to this question. When added together, the perimeter would be 13+13+5+5.

As an expression,

2(13)+2(5)

=26+10

=36.

The perimeter is approximately 36 meters.

Answers

Answer:

x = 7y = 37

Step-by-step explanation:

You want to know the values of x and y that make the angle measures consistent with the triangles being congruent in the given figure.

Congruence

The side markings show congruent triangles with corresponding vertices (and angles) ...

  L (3x+24)° ⇔ P (8x -11)°

  M 84° ⇔ Q 84°

  N (2x +y)° ⇔ R (no marking)

Corresponding angles L and P have the same measure, so ...

  3x +24 = 8x -11

  35 = 5x . . . . . . . . add 11-3x

  7 = x . . . . . . . . . divide by 5

The measures of these angles are ...

  (3(7) +24)° = 45°

Angle sum theorem

The sum of the angles in each triangle is 180°, so the measure of angle N is found to be ...

  L +M +N = 180°

  45° +84° +N = 180°

  N = 51°

This lets us find the value of y from ...

  (2x +y)° = 51°

  2(7) +y = 51

  y = 37 . . . . . . . . subtract 14

The value of x is 7. The value of y is 37.

Answers

3589.9 m is the height at which air pressure equals 65% of the air pressure at the surface of the Earth

How to find the height at which air pressure equals 65% of P₀?

Given: the function P(h) =P₀ e^(-0.00012h)

When air pressure equals 65% of the air pressure at the surface of the Earth. That means P = 0.65P₀

Substitute P = 0.65P₀ into the function:

P(h) = P₀ e^(-0.00012h)

0.65P₀  = P₀ e^(-0.00012h)

Dividing both sides by P₀ gives:

0.65  = e^(-0.00012h)

Take ln of both sides (ln is the inverse of e):

ln 0.65 = -0.00012h

h = ln 0.65/ (-0.00012)

h = 3589.9 m

Therefore, the height at which air pressure equal 65% of the air pressure at the surface of the Earth is 3589.9 m. Option D is the answer

If Triangles ABC and DEF are similar. Side length AB is 2, side length AC is 4, and side length BC is 3 Side length DE is 1.34 then  length of  DF = 2.68 and length of  EF = 2.01

What are Similar Triangles?

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion .

Given,

Triangles ABC and DEF are similar.

AB = 2

AC = 4

BC = 3

DE = 1.34

We need to find the length of DF and EF

Given that ABC and DEF are similar, therefore:

AB/DE = BC/EF = AC/DF

2/1.34=3/EF=4/DF

1.49=3/EF=4/DF

Now,

1.49=3/EF

EF=3/1.49

EF=2.01

1.49=4/DF

Answers

The distance each player ran for warm up laps is 875 cm and the distance each player ran for the store is 1.47 meters.

According to the question,

We have the following information:

Adrianna’s football team ran some warm up laps with a total distance of 6125 centimeters. There are 7 players on her football team.

The distance to the store = 10.31 meters

Now, we can find the distance ran by each player by dividing the total distance by number of players.

Distance for warm up laps = 6125/7

Distance ran by each player = 875 cm

Distance for the store = 10.31/7

Distance for the store = 1.47 m

Hence, the distance each player ran for warm up laps is 875 cm and the distance each player ran for the store is 1.47 meters.
