Camila and her children went into a grocery store and where they sell apples for $0.50 each and mangos for $0.75 each. Camila ha
german

Maximum number of mangoes that Camila can buy are 5

Step-by-step explanation:

  • Step 1: Find the cost of 8 apples bought by Camila.

Cost of 1 apple = $0.50

Cost of 8 apples = $0.50 × 8 = $4

  • Step 2: Find the remaining amount with Camila after she bought 8 apples.

Total amount that can be spent = $7.75

Cost of apples = $4

Remaining amount = $7.75 - $4 = $3.75

  • Step 3: Find the number of mangoes she can buy

Cost of 1 mango = $0.75

Number of mangoes = $3.75/$0.75 = 5

If the standard volume of a
Alla [95]

Answer:

6.7 %

which agrees with answer A in your list.

Step-by-step explanation:

If the standard volume is 1.5 cubic cm, and the measured volume is 1.6 cubic cm, then the difference between these two is :

1.6 - 1.5 = 0.1 cubic cm. and therefore the percentage error is given by:

0.1/1.5 = 0.066666...which corresponds to a rounding of 6.7%

Recall as well that percent error is always expressed as a positive number.

What are the best approximations of the solutions to this system?
Scilla [17]

(-1.2,-2.0) and (1.9,2.2) are the best approximations of the solutions to this system.

Option B

<u>Step-by-step explanation:</u>

Here, we have a graph of two functions from which we need to find the approximate value of common solutions. Let's find this:

First look at where we have intersection points, In first quadrant & in third quadrant.

<u>At first quadrant:</u>

Draw perpendicular lines from x-axis & y-axis from this point . After doing this we can clearly see that the perpendicular lines cut x-axis at x=1.9 and y-axis at y=2.2. So, one point is (1.9,2.2)

<u>At Third quadrant:</u>

Draw perpendicular lines from x-axis & y-axis from this point. After doing this we can clearly see that the perpendicular lines cut x-axis at x=-1.2 and y-axis at y=  -2.0. So, other point is (-1.2,-2.0).

Using proportions, the expected number of adults in Palm City whose main source of news is the internet or newspaper is of 19,413.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

From the table, the proportion of adults in Palm City whose main source of news is the internet or newspaper is found as follows:

p = (62 + 88)/(62 + 88 + 128 +24 + 38) = 0.4412.

Hence, out of 44,000 adults, the expected number is found as follows:

0.4412 x 44000 = 19,413.
