The distance from Alison's house to the mailbox is 2/5 mile. The distance from the mailbox to the bus stop is 1/3 mile. What is the total distance from Alison's house to the bus stop? 3/15 11/15 5/6 3/8

Answers

Answer:

Option B is correct

Step-by-step explanation:

Given

Distance from Alison's house to the mailbox  = [tex]\frac{2}{5}[/tex] miles

Distance from the mailbox to the bus stop [tex]\frac{1}{3}[/tex] miles

The total distance between Alison's house to the bus stop is

[tex]\frac{2}{5} + \frac{1}{3} \\\frac{6+5}{15} \\\frac{11}{15}[/tex]

Hence, option B is correct

A person wants to purchase a pair of shoes and some pairs of socks. He has less than $121 to
spend. If a pair of shoes costs $30 and each pair of socks costs $8, what is the maximum
number of pairs of socks he can purchase?

Answers

the answer is 11

first you need to subtract 30 from 121 since you want one pair of shoes

then to know how many socks you can have divide 91 (the result) and 8 (the price of the socks)

and you can only buy 11

Ivan and Tanya share £150 in the ratio 4:1
Work out how much more Ivan gets compared to Tanya.

Answers

Given: Ivan and Tanya share £150 with a 4:1 ratio.

Let x represent the variable amount of money.

Ivan: 4x
Tanya: x

4x + x = £150
5x = 150
x = 30

Ivan = 4(30) = £120
Tanya = £30

£120 - £30 = £90

Therefore Ivan gets £90 more than Tanya, which is four times more than Tanya.

Find the median of the following numbers:
95, 113, 95, 105, 86, 122

Answers

Answer:

100

Step-by-step explanation:

First, order the numbers from least to greatest.

86, 95, 95, 105, 113, 122

Second, look for the middles numbers, if you have an even amount of numbers you will have to find the mean of the two middle numbers.

86, 95, 95, 105, 113, 122

Thirdly, add 95 and 105 together and then divide by two because two is the total amount of numbers you have.

(95 + 105) / 2 = 100.

So the median is 100

A city's population increases by 5% every year. If its population today is 300,000, write a function that models the population after x years.

Answers

Answer:

f(x) = 300,000(1.05)^x

Step-by-step explanation:

Use the exponential growth equation:

f(x) = a(1 + r)^x

Plug in 300,000 as a, since it is the original population:

f(x) = 300,000(1 + r)^x

The city's population is growing at 5% each year, so plug in 0.05 as r:

f(x) = 300,000(1 + 0.05)^x

f(x) = 300,000(1.05)^x

So, the function for the population growth is f(x) = 300,000(1.05)^x

Area of PXYS = 21 cm.

bcm
P
S

Answers

Answer:

The answer is below

Step-by-step explanation:

PQRS is a rectangle. The length of rectangle PQRS = 9 cm + b cm = (9 + b)cm

The breadth of PQRS = a. Hence:

Area of PQRS = length * breadth = (9 + b)(a) = 9a + ab

but Area of PQRS = 84 cm²

9a + ab = 84          (1)

In rectangle PXYS, length = QR = a cm, breadth = YS = b cm

Hence area of PXYS = length * breadth = (a)(b) = ab

But Area of PXYS = 21 cm²

ab = 21         (2)

substitute ab = 21 in equation 1:

9a + 21 = 84

9a = 84 - 21

9a = 63

a = 7 cm

ab = 21

7b = 21

b = 3 cm

Therefore a = 7cm, b = 3 cm
