Answers

Answer 1
The answer would be A. 18 divided by 15 would be 1.2 so then you would multiply 1.2 by 20 and that’s 24.

Theresia picked the same number of tomatoes each day. In 4 days she picked 52 tomatoes. How many tomatoes did Theresia pick each day?

Let n represent the number of tomatoes Theresia picked each day.

Convince Me! Which property of equality can you use to solve Theresia’s equation? Explain.

Answers

Helloooo each day she picked 13 tomatoes

4(n)=52

That’s what I put as equation and they want to know how many tomatoes she picked each day which we don’t know so we use it as a n and we know the total 53 so we made equation like this then I divided 53 by 4 and put 13 in n and did the solving and got the same answer

What is the slope of the line shown below?

Answers

Answer:

-2/1

Step-by-step explanation:

Rise over run. The line goes up 2 blocks, and over 1. It's a negative because The line is going downward.

Answer:

The slope is -2

Step-by-step explanation:

Let's find the slope between your two points.

(−4,3); (−3,1)

(x1, y1) = (−4, 3)

(x2, y2) = (−3, 1)

Use the slope formula:

m = y2 − y1 / x2−x1

= 1 − 3 / −3 − −4

= −2 / 1

= −2

Answer:

m = −2

Isaac and Juanita are collecting apple to make an apple pie. Isaac picks up 3 apples every minute and Juanita picks up 5 apples every two minutes. If they need 40 apples for a pie, about how long will it take both of them to collect enough apples?

Answers

Answer:

It will take them roughly 7.27 mintues

Step-by-step explanation:

To find this, model the amount of apples that can collect a minute using m as the minutes.

Isaac = 3m

Juanita = 5m/2

Now we can add them together and solve for when they will have 40 apples.

3m + 5m/2 = 40

5.5m = 40

m = 7.27

Answer:

about 7 minutes (7.27 minutes to be exact)

Step-by-step explanation:

Since they are working as a team, we can combine the two rates to see how many apples they collect together per minute. Isaac collects 3 p/min while Juanita collects 2.5 p/min equaling 5.5 apples p/min. 40 apples divided by 5.5 equals 7.27 minutes.

which number is the same as for the power of negative 1 * 2 ^ 8 / 4 ^ -2
A) -2
B) 1/5
C) 2
D) 32
E) 512

Answers

B) 1/5.....................

Answer: D) 32

Step-by-step explanation:

To solve the expression (4 to the negative power of 1)(2 to the 3rd power divided by 4 to the negative power of 2), we can follow these steps:

Step 1: Simplify 4 to the negative power of 1

4 to the negative power of 1 can be written as 1/4 to the positive power of 1, so the expression becomes: (1/4)(2 to the 3rd power divided by 4 to the negative power of 2)

Step 2: Simplify the division of powers of 4

When dividing powers with the same base (in this case, 4), we can subtract the exponents. So, 4 to the negative power of 2 is the same as 1/4 to the power of 2, which equals 1/16. The expression now becomes: (1/4)(2 to the 3rd power divided by 1/16)

Step 3: Simplify 2 to the 3rd power 2 to the 3rd power is 2x2x2, which equals 8. The expression now becomes: (1/4)(8 divided by 1/16)

Step 4: Simplify the division

Dividing by a fraction is the same as multiplying by its reciprocal. So, we can rewrite the expression as: (1/4)(8 x 16)

Step 5: Multiply 8 x 16 equals 128, so the expression simplifies to: (1/4)(128)

Step 6: Simplify the final expression

Multiplying 1/4 by 128 gives us 32. Therefore, the final answer is: 32

A. 7,300 meters
B. 730 meters
C. 73,000 meters
D. 73 meters

Answers

Hey there! The answer would be A. 7,300 meters.


This is because there is 1000 meters in a kilometer. To get this answer, we need to multiply 7.3 and 1000. This results in 7,300. :)

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.

We are given the dimension of the polygon.

We need to find the perimeter of the polygon shown. so just add the dimensions then we get;

30-2x + 2x-4 + 18 + x+7 + 3x +4x+1

= 52 + 8x
