A store sells both cold and hot beverages. Cold beverages, c, cost $1.50, while hot beverages, h, cost $2.00. On Saturday, drink

receipts totaled $360, and 4 times as many cold beverages were sold than hot beverages. Which system of linear equations represents the beverage sales on Saturday? 4c = h 1.5c + 2h = 360 c = 4h 1.5c + 2h = 360 c + h = 360 1.5c = 4(2h) c + h = 360 4(1.5c) = 2h

Answer:

The equations that  represents the beverage sales on Saturday are:

1.5c+2h=360

c=4h

Step-by-step explanation:

Let the cold beverages be denoted by = c

Let the hot beverages be denoted by = h

Cost of c = $1.50

Cost of h = $2

On Saturday, drink receipts totaled $360

Equation becomes => 1.5c+2h=360

Also, 4 times as many cold beverages were sold than hot beverages.

Equation becomes => c=4h

Hence, the correct options are :

1.5c+2h=360

c=4h

2h + 4h  (1.5c) = 360 so option b is correct.

Suppose two different methods are available for eye surgery. The probability that the eye has not recovered in a month is 0.002
umka21 [38]

Answer:

0.4007

Step-by-step explanation:

Let's define the following events:

A: method A is used

B: method B is used

NR: the eye has not recovered in a month

R: the eye is recovered in a month

The probability that the eye has not recovered in a month is 0.002 if method A is used, i.e., P(NR|A) = 0.002, so P(R|A) = 0.998.

When method B is used, the probability that the eye has not recovered in a month is 0.005, i.e., P(NR|B) = 0.005, so P(R|B) = 0.995.

40% of eye surgeries are done with method A, i.e., P(A) = 0.4

60% of eye surgeries are done with method B, i.e., P(B) = 0.6

If an eye is recovered in a month after surgery is done in the hospital, what is the probability that method A was performed? We are looking for P(A|R), then, by Bayes' Formula

P(A|R) = P(R|A)P(A)/(P(R|A)P(A) + P(R|B)P(B)) = 0.998*0.4/(0.998*0.4 + 0.995*0.6) = 0.4007

John is 4 years older than Becky, and John’s and Becky’s combined ages is 58. How old are Becky and John?A. Becky is 26; John is
Levart [38]

Answer:

Answer C: Becky is 27; John is 31

Step-by-step explanation:

1. John is 4 years older than Becky--27(Becky's age)+ 4=31(John's age)

2. Sum of their ages is 58--27(Becky's age)+31(John's age)=58

So, the correct answer is Answer C.

The diagram shows some land in the shape of a quadrilateral ABCD. AB = 6 km, AD = 5 km and CD = 12 km Angle BAC = 30 The land is
Goshia [24]

Answer:

£495 million

Step-by-step explanation:

To find out the total cost of the land, we need to first calculate the area of the land.

Step 1: Find area of right angled triangle ADC

AD = 5 km,

DC = 12 km

Area of the right triangle = ½*a*b

a = 5km

b = 12km

Area = ½*5*12

= 5*6

Area of ADC = 30 km²

Step 2: Find the area of triangle ABC

First, let's find the length of AC using Pythagorean theorem

AC² = AD² + DC²

AC² = 5² + 12² = 25 + 144

AC = √169

AC = 13km

Area of ∆ABC = ½*AB*AC*sin(30°)

= ½*6*13*0.5

= 3*13*0.5

Area of ∆ABC = 19.5 km²

Total area of the land = area of ∆ADC + ∆ABC = 30 + 19.5 = 49.5 km²

Step 3: calculate how much the land costs

If the land costs £10 million per km²,

Cost of 49.5 km² = 49.5 × 10 = £495 million

If line b is perpendicular to line a, and line c is perpendicular to line a, what is the slope of line c?
slega [8]

we know that

If line b is perpendicular to line a, and line c is perpendicular to line a,

then

line b and line c are parallel

and two lines parallel have the same slope

so

<u>Find the slope of the line b</u>

Let

A(-3,-2)\\B(2,3)

The formula to calculate the slope between two points is equal to

m=\frac{(y2-y1)}{(x2-x1)}

(x1,y1)=(-3,-2)\\(x2,y2)=(2,3)

substitute

m=\frac{(3+2)}{(2+3)}

m=\frac{(5)}{(5)}

m=1

therefore

<u>the answer is</u>

<u>the slope of the line c is</u>

mc=1

Consider the equation 1.5x+4.5y=18. For each question, explain or show your reasoning.
Alchen [17]

Given:

The equation is

1.5x+4.5y=18

To find:

The y-intercept (in ordered pair).

Solution:

We have,

1.5x+4.5y=18

Putting x=0, we get

1.5(0)+4.5y=18

0+4.5y=18

4.5y=18

Divide both sides by 4.5.

y=\dfrac{18}{4.5}

y=4

So, y-intercept is 4.

Therefore, the graph intersect the y-axis at (0,4).
