write an equivalent ratio to 2:7​

Answer:

All multiples of 10 end with 0 only. So 35 must be wrong as it ends with 5. Therefore, Greg is incorrect.

Answer:

The relationship between angle 1 and angle 2 is that they both have the same value and are congruent angles. Because angle 1 is 108 degrees, angle 2 is also 108 degrees.

Answer:

1

Step-by-step explanation:

let the number=x

x-4=-3x

x+3x=4

4x=4

x=4/4=1

The number that is four greater than three times its additive inverse

is - 3n + 4.

A number's additive inverse is a number that is added to it until the result is zero.

A number multiplied by another such that the result is 1 is the multiplicative inverse of that number.

Let the unknown number be 'n' so its additive inverse is '-n'.

So,  the number that is four greater than three times its additive inverse is,

Three times of additive inverse is -3n.

Now the number is 4 greater than 3 times its additive inverse which is

= - 3n + 4.

The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:

2/8 = j/18

This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:

2/8 = j/18

218 = 8j

36 = 8*j

j = 36/8

j = 4.5

Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.

Answer:

Step-by-step explanation
2 over 8 equals j over 18

This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.

So, the correct proportion is:

Answer:

To find the output of the function f(x) = 3x - 2 when x = 1.5, we simply substitute 1.5 for x in the function rule and simplify:

f(1.5) = 3(1.5) - 2

f(1.5) = 4.5 - 2

f(1.5) = 2.5

Therefore, the output of the function f(x) when x = 1.5 is 2.5.

Answer:

f(x)- x = 1.5 is 2.5.

Answer: (6,3)

Step-by-step explanation:

The midpoint of AC and BD are the same because a rectangle's diagonals cut each other in half.

D = A + C - B

D = 2 + 5 - 1 = 6

D = 1 + 5 - 3 = 3

D = (6, 3)

Answer:

8

Step-by-step explanation:

You multiply the candies sold, by 8 to get the money raised.

10 times 8 is 80.

20 times 8 is 160

30 times 8 is 240

And so on.

I hope this helps!

pls ❤ and give brainliest pls

Divide money raised by candles sold:

80/10 = 8

160/20 = 8

Etc.

Each candle cost $8

You would multiply the number of candles sold by $8 to find the amount of money raised.

Answer:

For one of them, it will be B=(4.5, 1.5). The sides would each be 3.54 long.

For the second, B=(1.5,5.5). Lines AB and CB are also going to be 3.54 long.

Step-by-step explanation:

My thought process was all over the place, to be honest with you. I drew out the points on some graph paper and found out the length of AC, which is 5. Then I thought I could use the law of sines since we know that the other two angles are both 45 degrees. Anyways, I got the lengths as 3.5. I was a bit off, but I found that out later. I thought of using a compass to try to see where a point would meet if there is a distance of 3.5, but I don't have a compass, so I went searching for online ones. I couldn't find one with a graph in it, so I used an online graphing system. From the beginning, I knew that it was probably going to be something .5, so I kept on trying to find a spot that had a length of 3.5 on both sides, and got really close, but they were still off. I checked where B was graphed, and it was a really long decimal, so I just put it to .5 on both the y and x and voila, I got 3.54 on both lines AB and CB. I, of course, checked my answers and found that the angle was in fact 90 degrees and I felt very pleased with myself. I did a simpler version for the other angle.

I hope this is correct! Please let me know, this was really fun anyways!

Answer:

31.2 miles

Step-by-step explanation:

x = 31.2

Hope this helps:)

Answer:

31.2 miles

Step-by-step explanation:

5 in.: 12 mi

13 in: 12 mi

5/13 = 12/x

5x = 156

x = 31.2

Answer:

Basically, you have to plug either the x into the equation to get the y, or the y into the equation to get the x. so:

i = 21

ii = 9

iii = 0.5

Step-by-step explanation:

The Main Equation : y = 4(x) - 3

i = 4(6) - 3

i = 24 - 3

i = 21

33 = 4(ii) - 3

36 = 4(ii)

9 = ii

-1 = 4(iii) - 3

2 = 4(iii)

0.5 = iii

Answer:

  4600 miles

Step-by-step explanation:

You want to know the difference in miles per hour between a satellite traveling 45000 miles in 5 hours and one traveling 79200 miles in 18 hours.

The speed in miles per hour is the ratio of miles to corresponding hours. The difference in miles traveled in one hour will be ...

  A speed - B speed

  45000 mi/(5 h) - 79200 mi/(18 h) = 4600 mi/h

Explorer B travels 4600 fewer miles in an hour than Explorer A.

Step-by-step explanation:

So, we know that the width in this image has a length of 7 feet. decreasing it by two will give us 5 feet. Now, we can solve the surface area.

Lateral faces: 7 x 14 x 4 = 392

Bases: 14 x 13 x 2 = 364

Add them all up, and we get 756 ft²

1 feet = 12 inches

Note : We just need to judge whether it accords with "y = kx"

{Proportional relationship}

74 meters

Step-by-step explanation:

The difference in Emile and Henry's speed is 1.5, and the lead for Henry is 45 meters, so 45÷1.5= 30 seconds which means Henry will go another 30 meters at 1 meter per second.

2. To make it a close race we want Henry to go a longer distance than Emile, so make it 74 meters, which means Emile will go only have 45+29 = 74 seconds to get to 74 meters, but Henry only have 29 seconds in total = 29*2.5 = 72.5 meters.

Answer:

He ran 3.25 on Tuesday

Step-by-step explanation:

The answer is 3.25 because 5.55 minus 2.3 is 3.25.

Answer:

3.25 miles

Step-by-step explanation:

Let's use x as a placeholder for the number you don't know yet.

2.3+x=5.55

To get the x by itself, we need to subtract 2.3. Remember, whatever we do to one side we have to do to the other side.

x=5.55-2.3

Now we must subtract 2.3 from 5.55.

5.55-2.3=3.25

Now we know:

x=3.25

Since the question asks for the answer in miles, we can say that Trevor ran 3.25 miles on Tuesday.

Answer:

you have four walls. two of them 12*8 and the other two are 10*8 ( we used 8 in both because it's the height of the room). so it goes( 2*12*8)+(2*10*8) and it goes 352S

Step-by-step explanation:

let's say that walls A 12*8 and walls B 10*8. you have 4 walls ta wallpaper.

for walls A= 2*12*8=192

for walls B=2*10*12=160

in total, you need 160+192= 352 square feet of wallpaper
