Answers

Answer 1

Answer: 1st find discount
18-13=5
5 is discount

discount from original
5/18=x%
percent means parts out of 100 so x%=x/100
5/18=x/100
multiply both sides by 900
250x=9
divide both sides by 250
x=27.77777

3x + 5y = 55
5x + 4y = 57

Answers

Answer:

x=5, y=8. (5, 8).

Step-by-step explanation:

3x+5y=55

5x+4y=57

---------------

5(3x+5y)=5(55)

-3(5x+4y)=-3(57)

-------------------------

15x+25y=275

-15x-12y=-171

---------------------

13y=104

y=104/13

y=8

3x+5(8)=55

3x+40=55

3x=55-40

3x=15

x=15/3

x=5

Bernardo hiked 12.8 km in June and 13.4 km in July. Nicole hiked the same total distance as Bernardo but hiked only 11.5 km in June. How far did Nicole hike in July? A. 14.7 km B. 12.8 km C. 13.1 km D. 1.9 km

Answers

Total distance hiked by Bernardo in June = 12.8 km
Total distance hiked by Bernardo in July = 13.4 km
Then
The total distance hiked by Bernardo in June and July = (12.8 + 13.4) km
= 26.2 km
Now it is given in the question that Nicole hiked for the same total distance in June and July.
Also it is given that
The distance hiked by Nicole in June = 11.5 km
Then
the distance hiked by Nicole in July = (26.2 - 11.5) km
= 14.7 km
So the distance hiked by Nicole in July is 14.7 km. The correct option among all the options given in the question is option "A".

Nicole hiked 14.7 km
on July
So the right answer is:
A: 14.7 km

Answers

Q1. The answer is d) 13 to 18

There are 13 pens and 18 pencils. Ratio of pens to pencils can be written as:
pens : pencils

Since pens = 13 and pencils = 18, then
pens : pencils = 13 : 18

Or in other words, ratio of pens to pencils is 13 to 18. Thus, choice d) is correct.

Q2. The answer is C.5 to 8

There are 12 tulips and 20 roses. The total number of flowers is 12 tulips + 20 roses = 32 flowers. Ratio of roses to the total number of flowers can be written as:
roses : total flowers

Since roses = 20 and total flowers = 32, then
roses : total flowers = 20 : 32

Now, let's simplify 20 to 32 ratio:
20 : 32 = (20 / 4) : (32 / 4) = 5 : 8

Or in other words, ratio of roses to the total number of flowers is is 5 to 8. Thus, choice C. is correct.

Q3. The answer is 3 : 4

There are 30 one-story homes and 24 two-story homes. Ratio of two -story homes to one-story homes can be written as:
two-story homes : one-story homes

Since one-story homes = 32 and two-story homes = 24, then
two-story homes : one-story homes = 24 : 32

Now, let's simplify 24 to 32 ratio:
24 : 32 = (24 / 8) : (32 / 8) = 3 : 4

So, the ratio of one-story homes to two-story homes is 3 to 4.

Q4. The answer is

There are 16 trading cards and 2 wildlife cards. Ratio of wildlife cards to total trading cards can be written as:
wildlife cards : trading cards

Since trading cards = 16 and wildlife cards = 2, then
wildlife cards : trading cards = 2 : 16

Now, let's simplify 2 to 16 ratio:
2 : 16 = (2 / 2) : (16 / 2) = 1 : 8

So, the ratio of wildlife cards to total trading cards is 1 : 8

Q5. The answer is

There are 3 cobblers. The total number of baked goods is 12 cookies + 9 pies + 8 cakes + 4 tarts + 3 cobblers = 36 baked goods. Ratio of the total number of baked goods to cobblers can be written as:
baked goods : cobblers

Since baked goods = 36 and cobblers = 3, then
wildlife cards : trading cards = 36 : 3

Now, let's simplify 36 to 3 ratio:
36 : 3 = (36 / 3) : (3 / 3) = 12 : 1

So, the ratio of the total number of baked goods to cobblers is 12 : 1
