Answer:

5y + 7

Step-by-step explanation:

Given:

Seeds planted in one garden = y vegetable seeds

Seeds planted in another garden = 4y + 7 vegetable seeds

To Find:

The number of seeds Val is going to plant = ?

Solution:

Let the total number of seeds that Val is going to plant be x.

Then

x = number of seeds planted in garden one + number of seeds planted in the other garden

Now substitute the values, we get

x = y + (4y+7)

x = 5y + 7

Since 2003 median home prices in Midvale, UT have been growing exponentially at roughly 4.7 % per year. If you had purchased a h

Kipish [7]

Answer:

The home would be worth $249000 during the year of 2012.

Step-by-step explanation:

The price of the home in t years after 2004 can be modeled by the following equation:

$P(t) = P(0)(1+r)^{t}$

In which P(0) is the price of the house in 2004 and r is the growth rate.

Since 2003 median home prices in Midvale, UT have been growing exponentially at roughly 4.7 % per year.

This means that $r = 0.047$

$172000 in 2004

This means that $P(0) = 172000$

What year would the home be worth $ 249000 ?

t years after 2004.

t is found when P(t) = 249000. So

$P(t) = P(0)(1+r)^{t}$

$249000 = 172000(1.047)^{t}$

$(1.047)^{t} = \frac{249000}{172000}$

$\log{(1.047)^{t}} = \log{\frac{249000}{172000}}$

$t\log(1.047) = \log{\frac{249000}{172000}}$

$t = \frac{\log{\frac{249000}{172000}}}{\log(1.047)}$

$t = 8.05$

2004 + 8.05 = 2012

The home would be worth $249000 during the year of 2012.

The ratio of nonfiction books to fiction books in a library is 105 to 189. Which statement describes this relationship?

kolezko [41]

Answer: A)There are 5 nonfiction books for every 9 fiction books in the library.

Step-by-step explanation: If you do the math you realize that there are clearly less nonfiction books than fiction books.

105/5=21 and after 21*9 lines up and to check your work than

5*21=105 and 9*21=189 it is not B because the smaller number 105 is in front of the ratio 105:189 and 5:9

Tori examined the pattern of exponents in the table.

gregori [183]

Answer:

The value of b = 1/36

As exponent decreases, each previous value is divided by 6

If the table was extended, the value of 6^-3 would be 1/216

Step-by-step explanation:

Given in the question a table containing power of 6

We will use negative rule of exponent to write the equivalent of negative power of 6

b^{-n}= 1 / b^{n}

we know that

$6^{1}=6$

$6^{-1} =\frac{1}{6^{1} }$

= 1/6

and

$6^{2} = 36$

So,

$6^{-2} = \frac{1}{6^{2} }$

$\frac{1}{36}$

A phone company offers two monthly plans. Plan A costs 8 plus an additional 0.16 for each minute of calls. Plan B costs 20 plus

blagie [28]

Answer:

Total time when cost are equal = 600 minutes

Total cost = 104

Step-by-step explanation:

Given:

Plan A = costs 8 plus an additional 0.16 for each minute

Plan B = costs 20 plus an additional 0.14 for each minute

Find:

Total time when cost are equal

Computation:

Assume total time = x minutes

Plan A = 8 + 0.16x

Plan B = 20 + 0.14x

Plan A = Plan B

8 + 0.16x = 20 + 0.14x

0.02x = 12

x = 600 minutes

Total time when cost are equal = 600 minutes

Total cost = 8 + 0.16x

Total cost = 8 + 0.16(600)

Total cost = 104
