Write 15 cookies to 40 brownies as a ratio in simplest form.

Answers

The equation for this question to reach the ratio in its simplest form would be 15:40 15 divided by 5 = 340 divided by 5 = 8, 3 : 8

if we write the ratio 15 cookies to 40 cookies we will get the following ratio

15:40

to write in simplest form we have to find the highest common factor for both 15 and 40

the factors for both 15 and 40 are as follows

15 - 1,3,5,15

40 - 1,2,4,5,8,10,20,40

the highest common factor is 5

so we have to divide both ny 5 to get the simplest form

(15)/(5):(40)/(5)  = 3:8

ratio in the simplest form is 3:8


28 Rowan raised $640 in a charity walk last year. This year he raised 15% more than he raised last year. How much money did Rowan raise this year?

Answers

rowan raised 640 last year
this year he raised 15% more
percent means parts out of 100
15%=15/100=3/20
15% of 640
'of' can be translated as multiply
15%=3/20
3/20 times 640=1920/20=192/2=96
this is 15%
he raised 15% MORE SO
640+96=this year=736

he raised 736 dollars this year
640$ - is 100% - in last yearin this year is 15% more, so 100+15=115%make proportion640 is 100%x is 115%x=640*115/100=736$Answer: Rowan raised 736$ this year

ANSWER PLEASE I WILL MARK AS BRAINLIEST

Answers

Answer:

162 mL  

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

V = \text{2 fl oz} * \frac{\text{29.57 mL}}{\text{1 fl oz}} = \textbf{59 mL}

(c) Banana flavouring

V = (1)/(2)\text{ tsp} * \frac{\text{4.928 mL}}{\text{1 tsp}} = \textbf{2.5 mL}

2.Calculate the total volume

Chlorpheniramine =  100  mL

Lidocaine               =   59

Banana flavouring =    2.5      

TOTAL                    = 162 mL

Can someone help me with this two problems?

Answers

2x+4y=0

substitute y with 0

2x+4(0)=0

solve the equation

2x+0=0

2x=0

divide by 2 on both sides

x=0

4x+8y=7

substitute y with 0

4x+8(0)=7

solve the equation

4x+0=7

4x=7

divide by 4 on both sides

x=7/4 or x=1 3/4 or x=1.75

3x-7y=-29

2x+2y=6

solve the bottom equation

3x-7y=-29

x=3-y

substitute for x

3(3-y)-7y=-29

solve the equation

y=19/5

now substitute for y

x=3-(19)/(5)

solve for x

x=-4/5

the possible solution of the system is the ordered pair

(x,y)=(-(4)/(5) ,(19)/(5))

You receive 9 text messages in 12 minutes. What is the rate of text messages per hour?

Answers

Answer:

45(messages)/(hour)

Step-by-step explanation:

we know that

To find the rate  of text messages per hour, first divide the total messages by the total time in minutes

so

(9)/(12)=0.75(messages)/(minute)

Convert to messages per hour

Remember that 1\ hour=60\ minutes

Multiply by 60

0.75*60=45(messages)/(hour)

9 text messages in 12 min ⇒ how many text messages in 60 min 
9×60÷12 = 45 text messages :))
