Yoon buys a box of markers for $2.85 but he has a coupon for 20% off how much does he save with the coupon

Answer:

4th one

Step-by-step explanation:

Answer:

Step-by-step explanation:

(sin5a-sina)+sin2a/(cos5a+cosa)+cos2a

=2cos3asin2a+sin2a/2cos3acos2a+cos2a

=sin2a(2cos3a+1)/cos2a(2cos3a+1)

=sin2a/cos2a

=tan2a

Answer:

12 cups

Step-by-step explanation:

I'm pretty sure you just take 20% of 15.. which is 3 and then you would do 15-3 which is 12. Hope this helps! <3

Answer:

12 cups

Step-by-step explanation:

if the volume decreases by 20%, that means 80% is left.

Step-by-step explanation:

Answer: $10

Step-by-step explanation:

Given

Robin and his four friends bought tickets for [tex]\$12[/tex] each

If each one of them bought a calculator then the total spendings are [tex]\$110[/tex]

Suppose the cost of each calculator is [tex]\$\ x[/tex]

Cost per person is given by  [tex]x+\$12[/tex]

For the group, it is [tex]5(x+12)[/tex]

Equate this to total spendings

[tex]\Rightarrow 5(x+12)=110\\\Rightarrow x+12=22\\\Rightarrow x=\$\ 10[/tex]

thus, the cost of each calculator is [tex]\$ 10[/tex]

Answer:

$0.13

Step-by-step explanation:

7.98/60 = 0.133

round down to 0.13

Answer:

I believe the answer is $0.13

Step-by-step explanation:

You need to divide the price of the air heads ($7.98) by how many bars there were in the box (60).  7.98/60= 0.133

Then you round the answer to the nearest hundredth: 0.133= $0.13

Answer:

Step-by-step explanation:

y-intercept (c)= 6

slope (m) = 3

Writing in slope intercept form

y = mx + c

y = 3x + 6

Answer:

c-a=B

Step-by-step explanation:

if A+B=c then you subtract a from c and you get b

Answer:

C. c - a = b

Step-by-step explanation:

a + b = c

There are many ways to rearrange this equation. This can be done through addition and subtraction.

First, let's handle a. a is positive; therefore, we should subtract it.

a + b = c

b = c - a

Next, let's handle b. b is also positive; therefore, we should subtract it.

a + b = c

a = c - b

Finally, we will handle c. c is once again positive; therefore we should subtract it. However, it is the only variable on the right side, which would leave 0. This is not an option, so we will not look at this.

From our options, we can see that we have produced: b = c - a

This is an option, which has been written as c - a = b.

Therefore, your answer is C. c - a = b

Hope this helps!

Answer:

Jeff finished first

Step-by-step explanation:

To solve this equation, I can either converts 2 minutes 2 seconds to seconds or convert 121 seconds to minutes

CONVERT 2 MINUTES 2 SECONDS TO SECONDS

60 seconds = 1 minutes

to convert 2 minutes 2 seconds to seconds, multiply 2 minutes by 60 and then add 2 seconds to it

2 x 60 = 120 seconds

120 seconds + 2 seconds = 122 seconds

Paul finished in 122 seconds while Jeff finished in 121 seconds. Jeff finished first

CONVERT 121 SECONDS TO MINUTES

60 seconds = 1 minutes

To convert 121 seconds to minutes, we have to divide by 60

121/60 = 2 minutes 1 second

Paul finished the race in 2 minutes 2 seconds while eff finished the race in 2 minutes 1 second. Jeff finished first

Answer:

YZ = 12.2

Step-by-step explanation:

YZ bisects XW and VW, therefore it is half of XV

Answer:

697.45

Step-by-step explanation:

interest for the first year = 13.5 % of 580 = 78.3

for 0.5 year, it will be 78.3 /2 =39.15

1year + 0.5 year = 78.3 + 39.15= 117.45

add that to borrowed amount to get total amount paid

117.45+ 580= 697.45

Answer:

$8.00 per child

Step-by-step explanation:

Mr. Jackman= $32

Children= 4

per child= $32/4

$8.00

Answer:

y=3*(-2)                                      

y=--(3*2)

y=-6

 y=-6

y=0x-6

y=0x+(-6)

y=0x+(-6),m=0

y=0x+(-6),m=0,b=-6

m=0,b=-6

  y=3x(-2)

Let x be the domain values.

Let x = -1

y = 3(-1) - 2

y = -6 - 2

y = -8...range

Our first ordered pair is (-1, -8).

Let x = 2

y = 3(2) - 2

y = 6 - 2

y = 4...range

Our second ordered pair is (2, 4).

Let x = 4

y = 3(4) - 2

y = 12 - 2

y = 10...range

Our third ordered pair is (4, 10).

Done.

Answer:

k = 102

Step-by-step explanation:

Inverse variation is represented as follows:

y = k/x

Find k by substituting 17 for y and 6 for x:

17 = k/6

Multiplying both sides by 6 results in k = 102

Answer: 143

90-53=37

180-37=143

Answer:

Step-by-step explanation:

The angle left to b is

90° - a

= 90° - 53°

= 37°

So now

< b + 37° = 180° ( being linear pair )

< b = 180° - 37°

< b = 143°

Answer:

E

Step-by-step explanation:

2c + 7 > 0

2c > -7

c > -7/2

If c < -7/2

-2c -7 -3 > 4

-2c > 14

c < -7

if c > -7/2

2c + 7 -3 >4

2c >0

c >0
