The intercepts are where the function graph crosses an axis. For example, your x-intercept is (5,0) because the function crosses the x-axis at this point. The y-intercepts are (0, +/- 1.5). The domain is whatever x-coordinates are crossed, in this case, -3 < x </= 5. The range includes any y-coordinates that are crossed. -2 < y < 2.

Christine runs 10 miles in 75 minutes. At the same rate, how many miles would she ru I miles

Len [333]

Answer:

$\frac{46}{5}$ miles [or, 9.2 miles]

Step-by-step explanation:

Complete Question:

Christine runs 10 miles in 75 minutes. At the same rate, how many miles would she ru n in 69 minutes?

Solution:

We need to find the unit rate first and then find our answer. To get unit rate, we need to know the number of miles she runs in "1 minute". So, we will divide number of miles by number of minutes, that is given. Hence:

$\frac{10}{75}=\frac{2}{15}$

That means in 1 minute, Christine runs 2/15th of a mile.

Now, we want to know how many miles she will run in 69 minutes. We simply multiply unit rate (2/15) by the number of minutes (which is 69). Thus we have:

$\frac{2}{15}*69=\frac{2*23}{5}=\frac{46}{5}$

In decimal, doing division, that is 9.2 miles

A company manufactures handband a wirleless

PIT_PIT [208]

Answer:

1. 21 represents the cost of manufacturing one handband.

3. The initial start up cost is $15000.

5. The company spends $57000 to manufacture 2000 handbands.

Step-by-step explanation:

We are given the cost function for manufacturing 'h' amount of handbands and it is provided that there was initial start up costs involved.

Now, as the cost function is given by, C(h) = 21h + 15000.

We can see that the initial start up cost is $15000.

As, 'h' is the number of handbands being made. So, 21h in C(h) is the cost of manufacturing 'h' handbands.

Therefore, 21 is the cost of manufacturing one handband.

Since, C(h) = 21h + 15000.

Substituting h = 2000, we get,

C(2000) = 21×2000 + 15000.

i.e. C(2000) = 42000 + 15000.

i.e. C(2000) = 57000.

The company spends $57000 to manufacture 2000 handbands.

Since, we are provided with only cost function, we can not talk about the profit.

Hence, option 1, 3 and 5 are correct.

1. The county fair charges $1.50 per ticket for the rides. Jermaine bought 20 tickets for the rides and spent a total of $48.75

MAVERICK [17]

Answer: Our variable be z for fair admission and our required linear equation will be

$\$1.50x+z=\$48.75$

Explanation:

Since we have given that

Cost per ticket for the rides =$1.50

Total amount she spent = $48.75

Let the total cost be y

Let the number of ride tickets be x

a) Define your variable:

Let the amount spent on fair admission be z

b) Write a linear equation that can be used to determine the cost for ride tickets and fair admission:

Our required equation will be

$\$1.50x+z=\$48.75$

Here, number of ride tickets = 20

So,

$20\times 1.50+z=48.75\\\\30+z=48.75\\\\z=48.75-30=18.75$

So, the cost for fair admission = $18.75
