***If you give me a ridiculous answer I will report faster than light itself.

Answers

Answer:

3 hours: 38,250

1 day: 122,440

I’m not sure if this is exactly right, my brain gave out half way. Someone check my answer pls

Step-by-step explanation:

3 hours:   3 x 60= 900

                 900 divided by 20= 450

                    450 x 85 = 38,250

1 day:       24 x 60 = 1440

                 1440 x 85 = 122,440

Answer:

3 hours: 38,250

1 day: 122,440

Step-by-step explanation:

3 hours:   3 x 60= 900

900 divided by 20= 450

There are 53 cans of tomato sauce on
the shelf, 24 cans of tomato paste and
16 cans of crush tomatoes.
What is the ratio of cans of tomato
sauce to crushed tomatoes?
What is the ratio of crushed tomatoes
to tomato paste?

Answers

53:16 and 16:24 for the second part
to find the ratio of cans of tomato sauce to crushed tomatoes, you just need to put the numbers of each together and put the word “to” in between the numbers or just add a colon (:). the number of cans of tomato sauce is 53, and the number of crushed tomatoes is 16, so the ratio is 53:16. The same goes for the next question. The number of crushed tomatoes is 16 cans, and the number of tomato paste is 24 cans. Since the ratio is the two numbers compared, the ratio is 16:24. Hope this helped!

Juliet deposited $9,000 into her savings account. The bank offers 2% interest. She invests her money for 6 months. How much money does she have in her account in total, including the interest? Show work.

Answers

Answer:

10,080 (assuming that Juliet gets 2% interest each month)

Step-by-step explanation:

The first step would be to figure out what's 2% of 9000 (180)

and then do 180*6 because she is investing for 6 months (1080)

and then add the 9000 and interest 1080 and you get 10,080

(for further questions please be more informative its important to know how much is gained per a period of time for example: if it where 2% interest every 2 months the answer would be very different )

In Bicycle Moto Cross (BMX) racing, racers purchase a one year membership to a track. They also pay a fee for each race at that track. One racer paid a total of $125 after 5 races. A second racer paid a total of $170 after 8 races. How much does the track membership cost? What is the fee per race?

Answers

Answer:

its 25

Step-by-step explanation:

if you divide 125 and 5 you get 25

then if you divide 170 and you get 21.25 but you want to round it to 25

hope this helps plz let me have brainliest

The fee per race is $15, while the membership fee is $50

A linear equation is given by:

y = mx + b;

Where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the number of race and y represent the total money, b is the membership fee and m is the pay per race, hence:

One racer paid a total of $125 after 5 races, hence:

125 = 5m + b   (1)

A second racer paid a total of $170 after 8 races, hence:

170 = 8m + b      (2)

Solving equation 1 and 2 simultaneously gives:

m = 15, b = 50

Hence the fee per race is $15, while the membership fee is $50

you would subtract 2 from both sides
i believe that’s A

Answer:

B

Step-by-step explanation:

The first step to solve the equation is to isolate x. And to isolate x, we need to remove the numerical value, which is +2, by adding two -1's to each side.

What is the value of x in the equation? 3 2/5x + 2 3/4 = 7

The length of a rectangle is shown.

If the area of the rectangle to be drawn is 10 square units, where should points C and D be located, if they lie vertically below the line that connects B and A, to make this rectangle?

C(−1, 1), D(1, 1)
C(−1, −2), D(1, −2)
C(−1, 5), D(1, 5)
C(−1, −7), D(1, −7)

Answers

Answer:

Second option

Step-by-step explanation:

It is given that, if the area of the rectangle to be drawn is 10 square units

To find the length of the rectangle

From the figure, we get the length of AB = 2 units

Therefore Area = length * breadth = 10

Therefore length = 10/2 = 5 units

To find the points of C and D

we have B(-1, 3)

Point C is 5 units below the point B

Therefore C(-1, 3-5) = C(-1,-2)

we have A(1, 3)

The point D is 5 units below the point B

Therefore D(1, 3-5) = A(1,-2)

Therefore the correct answer is option 2.

Answer:

B. C(-1, -2), D(1, -2)

Step-by-step explanation:

So we know the area of the shape is 10 square units, A and B are 2 units apart, what we need to do is multiply that by 5, so we would have to go 5 units down, which would get you down to (-1, -2), and (1, -2). So that's your Answer.
