Answer:

C. 350 - acres of pumpkins

Step-by-step explanation:

The Uncle owns 510 acres, and wants 190 more acres of pumpkin than squash totaling at 510.

When looking at the possible answers D is automatically wrong since the Uncle only owns 510 acres. When I added A and C I got 510 as an answer;

160 + 350 = 510

So he wants 190 more pumpkin acres than squash so 160 represents the squash and 350 represents the pumpkin.

160 + 190 = 350

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

Another way to find the answer is by taking 510 and subtracting 190 then dividing by two;

510 - 190 = 320

320 / 2 = 160

160 + 190 = 350

Then 160 would be squash and 350 would be pumpkin.

Answers

Answer:

One robot will be powered for an eighth of a day (1/8 of a day) by one quarter (1/4) of a bag of coffee.

Answer: 3 hours

Explanation: There are 24 hours in a day, and the robots use 2 bags of coffee a day, so you gotta do 24/2 and that means 1 bag of coffee lasts 12 hours. Next, the question is how long does 1/4 bag last, so you do 12/4 and get 3, therefore the correct answer is 3 hours. Hope this helped!

“Which of the following is most likely caused by chemical weathering” A.cirques carved out by a melting glacier
B. U-shaped valleys formed in a mountain region
C. Rocks and sediment transported and deposited
D.unrecognizable facial features on a marble statue

Answers

Answer:

D. Unrecognizable facial features on a marble statue

Step-by-step explanation:

The first 3 answer choices are all examples of physical weathering, not chemical weathering.

This is because the changes were caused by natural things such as flowing water and heating.

However, unrecognizable facial features on a marble statue would be caused by chemical weathering, where chemicals can erode marble and cause distortion in a statue.

So, D is the correct answer.

Cady has $3000 to deposit in the bank which offers 4% interest. How long does she need to leave the money in the bank in order to earn $600 in interest?

Answers

Answer:

Cady will have to leave the money in the bank for 5 years.

Step-by-step explanation:

Given that Cady has invested $ 3000 in an account with an interest rate of 4%, to know how much time must be invested to obtain $ 600 in interest, the following calculation must be performed:

3000 x 1.04 = 3.120

Thus, each year the investment will yield interest for $ 120. Therefore, since 600/120 is equal to 5, Cady will have to leave the money in the bank for 5 years.

There are four types of flowers in Mrs. Elliott’s garden, 1/2 of the flowers are red, 1/4 of them are purple. Of the remaining flowers, ⅔ are pink, there are 4 yellow flowers. How many flowers are there in Mrs. Elliott's garden?

Answers

Answer:

48 flowers.

Step-by-step explanation:

You know that there are red, purple, pink, and yellow flowers in the garden. Since you know that 1/2 are red and 1/4 are purple, the pink and yellow flowers (combined) must make up the remaining 1/4 of the garden.

You're told in the problem that of this remaining 1/4, 2/3 are pink. That must mean 1/3 are yellow. There are twice as many pink flowers as yellow flowers.

The problem also says there are 4 yellow flowers. This means that 1/3 (of the remaining 1/4) is equal to 4.

To figure out how many pink flowers there are, you can multiple 4 x 2. There must be 8 pink flowers.

To find the total number of pink and yellow flowers, add 8 + 4. There are 12 pink and yellow flowers.

Remember that the pink and yellow flowers must make up the remaining 1/4 of the garden. If 12 flowers is equal to 1/4 of the garden, then you can multiply by 12 x 4 to figure how many flowers are in the entire garden: 48 flowers.

Answers

Answer:

Step-by-step explanation:

The number of students in Mr.Romano’s class is 35.

Given that, in Mr. Romano‘s class, 40% of the students like baseball.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of students in Mr.Romano’s class be x.

Here, 40% of x = 14

⇒ 40/100 × x = 14

⇒ 0.4x = 14

⇒ x = 14/0.4

⇒ x = 35

Therefore, the number of students in Mr.Romano’s class is 35.

You have a square that has a side length of $1$ centimeter. Each minute, $2$ centimeters are added to the side length. After $10$ minutes, what will be the difference between the area of the last square and the area of the initial square in square centimeters (do not include the units in your answer)?

Answers

Answer:

Difference in area of the last square and the initial square = 440 cm²

Step-by-step explanation:

Length of the side of a square = 1 cm

Area of the square = (side)² = 1 cm²

Addition of side length every minute = 2 cm

After x minutes length of each side of the square = (1 + 2x) cm

If x = 10 minutes

Length of each side of the square = [1 + 2(10)]

                                                         = 21 cm

Area of the square after 10 minutes = (21)²

                                                            = 441 cm²

Therefore, difference in area of the last square and area of the initial square

= 441 - 1

= 440 cm²
