Answers

Answer 1

Answer:

Step-by-step explanation:

1. 31*9 = 279          

George has 279 marbles at home.

2. 49 + 97 = 146    

They have 146 marbles altogether.

3. 327 - 139 = 188  

Ashley has 188 more than Amber.

4. 111 - 56 = 55

He has 55 more marbles left.

5. 47*28 = 1316

Room 15 has 1316 marbles.

6. 1110/30 = 37

The average each child contributed would be 37 marbles.

7. 1056/11 = 96

Each boy received 96 marbles.

What is the correct expanded form and value of (One-fifth) Superscript 4?
One-fifth + one-fifth + one-fifth + one-fifth = StartFraction 4 Over 5 EndFraction
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
StartFraction 1 + 1 + 1 + 1 Over 5 times 4 EndFraction = StartFraction 4 Over 20 EndFraction
One-fifth times 4 = StartFraction 4 Over 5 EndFraction

Answers

Answer:

One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction

Step-by-step explanation:

1/5^4 = 1/5 * 1/5 * 1/5 *1/5 = 1/625

The expanded form of (One-fifth)⁴ is "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction," and its value is "StartFraction 1 Over 625 EndFraction."

              The expanded form of (One-fifth)⁴ can be derived by multiplying (1/5) four times. Each multiplication represents multiplying by one-fifth, resulting in "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction." This can be further simplified as "StartFraction 1 Over 625 EndFraction" by multiplying the numerators and the denominators separately.

              In mathematical terms, when we raise one-fifth to the power of 4, we are essentially multiplying one-fifth by itself four times. Thus, (One-fifth)⁴ is equal to "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction."

            Evaluating this expression yields the value "StartFraction 1 Over 625 EndFraction" since multiplying the numerators (1 * 1 * 1 * 1) and the denominators (5 * 5 * 5 * 5) results in 1 and 625, respectively.

           Mathematical representation:  \(\frac{1}{5}^4= \frac{1}{5} * \frac{1}{5} * \frac{1}{5} * \frac{1}{5}\)

Which statement is true about the equation 4.5z = 4.5z – 4.25 + 6.25? (1 point) It has no solution. It has one solution. It has two solutions. It has infinitely many solutions.

Answers

No solution

It’s no solution because if you would’ve subtracted 4.5z on both sides then the equation would’ve become:
0= -4.25+6.25
Which makes it a no solution since you can’t really solve the equation.

Answer: Wheref(the) is the distance in kilometers and the input the is the time in hours

BC f(t) = -5t + 40

CD f(t) = 20. Or f(t)= -20(t/t)+40 OR f(t) = 0t + 20

DE f(t) = -5(t-2) + 40

Step-by-step explanation:

The negative slope means that the distance is decreasing by 5 km/hr when there is movement. Between hours of 4 and 5, the slope is 0, but the distance remains constant at 20. All the options for CD are strange. But they describe the line segment in the graph.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?

Answers

Answer:

25.685 square feet.

Step-by-step explanation:

Circumference = 2 * π * radius

From this, we can derive the formula for the radius:

radius = Circumference / (2 * π)

Let's substitute the value of the circumference and calculate the approximate radius:

radius = 18 / (2 * π)

radius ≈ 18 / (2 * 3.14159)

radius ≈ 2.865 feet

Now that we have the approximate radius, we can calculate the area:

Area ≈ π * radius²

Area ≈ 3.14159 * (2.865)²

Area ≈ 3.14159 * 8.193225

Area ≈ 25.685 square feet

Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

We know that the circumference of a circle is given by:

C = 2πr

where C is the circumference and r is the radius of the circle.

In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:

18 = 2πr

Solving for r, we get:

r = 9/π ≈ 2.864 feet

Now we can use the formula for the area of a circle:

A = πr^2

Substituting the value we found for r, we get:

A = π(2.864 ft)^2 ≈ 25.85 ft^2

Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Help pls. Also wdym this is to short yk why so long &gt;:/

Answers

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.


Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.


Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

zoey is using an open number line. she wants to find 232+578. which addend should she place on the number line to start? explain

Answers

Answer:

To add 232 and 578, Zoey should start by placing the smaller addend, which is 232, on the number line. She can then add the larger addend, which is 578, by counting up from 232.

Here's how Zoey can do it:

Draw an open number line and label it from 0 to 800, with tick marks for every 100 units.Mark the starting point for 232 on the number line.To add 578, Zoey can count up from 232 by 100s until she reaches 578.She can count 100, 200, 300, 400, 500, and 600, which brings her to 832.However, she only needs to add 578, so she can stop at the point on the number line labeled 810.

Therefore, Zoey should place 232 on the number line to start adding 232 and 578.

Zoey should place the addend 232 on the number line to start.

What is Number Line?

A number line is a straight line drawn horizontally where the numbers are placed at an equal intervals.

Number line has numbers 232 and 578 marked at different points.

In order to find the sum of these two addends, we have to place the smaller addend at the start.

Here 232 is the smaller addend

578 is the larger addend.

Start with the smaller one, 232.

Then add the larger addend to it.

Hence the addend that should be started with is 232.

A local hamburger shop sold a combined total of 613 hamburgers and cheeseburgers on Wednesday. There were 63 more cheeseburgers sold than hamburgers. How many hamburgers were sold Wednesday

Answers

Answer:

This problem can be solved through the creation of a system of equations relating the number of hamburgers (x) and cheeseburgers (y).

 

Having a combined total of 603 hamburgers and cheeseburgers can be written as x+y=603 and having 53 more cheeseburgers than hamburgers can be written algebraically as y=x+53.

 

To solve the system:

x+y=603

y=x+53

 

Substitute what y equals in the second equation for y in the first equation:

x+(x+53)=603

2x+53=603

  -53    -53

2x=550

2    2

x=275 hamburgers

 

To solve for the number of cheeseburgers, substitute 275 for x in either equation.

y=x+53

y=275+53

y=328 cheeseburgers

 

To double check your work, make sure that 275+328=603 and that 328=275+53. Since both are true, you have solved for the number of hamburgers (275) and cheeseburgers (328).
