True ir false: multiplying 7x43, a reasonable estimate of the product is 280? Why?

Answers

No because 280 is 21 numbers away from 301

Final answer:

Multiplying 7 by 43 gives an exact result of 301. Thus, estimating this product as 280 isn't entirely accurate but might be seen as a reasonable approximation in certain contexts.

Explanation:

The statement 'multiplying 7 by 43, a reasonable estimate of the product is 280' is known as the question. For this multiplication equation, 7 x 43, the accurate result is 301. Therefore, estimating the product as 280 is not fully correct, however it is relatively close and might be considered a reasonable approximation depending on the context. For a stronger approximation, the product could be rounded up to 300.

A 32 mb memory stick can hold up to 491 images. How many images can 7 memory sticks hold?

Answers

7 memory sticks at 32 mb can hold 491 * 7 = 3437 images.

Final answer:

To find out how many images 7 memory sticks can hold, multiply the number of images one memory stick can hold by the number of memory sticks.

Explanation:

To find out how many images 7 memory sticks can hold, we need to multiply the number of images one memory stick can hold by the number of memory sticks. In this case, each memory stick can hold 491 images, so to find out how many images 7 memory sticks can hold, we calculate:

Number of images = Number of memory sticks × Number of images per memory stick = 7 × 491 = 3437 images

Therefore, 7 memory sticks can hold 3437 images.

Which expression is equivalent to-8+7.25-6+0.5

Answers

Final answer:

The expression equivalent to -8+7.25-6+0.5 is calculated by first adding the positive numbers to get 7.75, then adding the negative numbers to get -14, and finally combining these to get an equivalent expression of -6.25.

Explanation:

To find an expression equivalent to -8+7.25-6+0.5, you need to perform addition and subtraction operations in the order they appear because they have the same level of precedence. Adding positive and negative numbers together is simplified by combining like terms, often starting with the positive numbers for easier calculation.

First, add the positive numbers together: 7.25 + 0.5 equals 7.75. Next, add the negative numbers: -8 + (-6) equals -14. Finally, combine the sum of the positive numbers with the sum of the negative numbers: 7.75 + (-14) equals -6.25.

The equivalent expression is hence -6.25.

Suppose the Willard gold nugget was turned into 4 equal sized gold bricks. If one of the bricks was sold how many ounces of the Willard nugget would be left?

Answers

788/4= 197; 197 ounces for each golden brick.

---- 197x4= 788 so if 197 oz was sold then 788-197= 591oz.

> There would only be 591 oz left

The number of ounces left after one brick is sold is 591.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Willard gold nuggets = 788 ounces

The number of equal-sized bricks = 4

Now,

The number of ounces in each of the 4 bricks.

= 788/4

= 197 ounces

Number of bricks sold = 1

The remaining ounces.

= 788 - 197

= 591 ounces

Thus,

The number of ounces left is 591.

How do you convert 10/6 into a mixed number

Answers

Well, First you want to find out how many times six can go into ten. Since its only once, you immediately get the number 1 as your whole number. Now because you've taken six out of ten you're left with 4/6. The mixed number would be 1 and 4/6 or 1 and 2/3 if you're simplifying

Hi. To convert 10/6 into a decimal, you simply divide the bottom into the top. In this case, it would be 10 ÷ 6.

6 can go into 10 1 time and will have a remainder of 4. You bring the 4 up and place the 6 under it. This will give you the mixed number of 1 4/6 which can be reduced to 1 2/3

See the attached for a visual. Hope this helps. If you have further questions, please don't hesitate to ask.

15x=135
/15= /15
__________
x=9

It will take 9 months

Final answer:

Jones Middle School will have more students than Roberts Middle School after 9 months.

Explanation:

To find out after how many months Jones Middle School will have more students than Roberts Middle School, we need to determine the point at which the number of students at Jones Middle School exceeds the number of students at Roberts Middle School. Let's calculate the number of months it takes for this to happen:

Number of students at Jones Middle School = 850 + 5n (n represents the number of months)

Number of students at Roberts Middle School = 985 - 10n (n represents the number of months)

We need to find the value of n when the number of students at Jones Middle School is greater than the number of students at Roberts Middle School:

850 + 5n > 985 - 10n

Simplifying the inequality:

15n > 135

n > 9

Therefore, after 9 months, Jones Middle School will have more students than Roberts Middle School.

On a flight New York to London an airplane travels at a constant speed. An equation relating the distance traveled in miles d to the number of hours flying t is t= 1/500d. How long will it take the airplane to travel 800 miles?

Answers

Answer:

1.6 hours or 1 hour 36 minutes

Step-by-step explanation:

We have been given an equation [tex]t=\frac{1}{500}d[/tex], where d represents distance traveled in miles and t represents time in hours.

To find the time taken by the flight to travel 800 miles, we will substitute [tex]d=800[/tex] in our given equation as:

[tex]t=\frac{1}{500}\times 800[/tex]

[tex]t=\frac{800}{500}[/tex]

[tex]t=\frac{8}{5}[/tex]

[tex]t=1.6[/tex]

1 hour equals 60 minutes.

0.6 hours = 0.6*60 minutes = 36 minutes.

Therefore, it will take the plane 1.6 hours or 1 hour 36 minutes to travel 800 miles.

Using the equation, it is found that it will take 1.6 hours for the airplane to travel 800 miles.

The equation that relates the time in hours needed to travel d miles is given by:

[tex]t = \frac{1}{500}d[/tex]

In this problem, we want the time needed to travel 800 miles, thus [tex]d = 800[/tex], and:

[tex]t = \frac{1}{500}(800) = \frac{800}{500} = 1.6[/tex]

It will take 1.6 hours for the airplane to travel 800 miles.

Short Answers:

Answer for part A: Given
Answer for part B: Angle A = Angle D (not sure why this isn't in word bank?)
Answer for part C: ASA
Answer for part D: BC = EF
Answer for part E: CPCTC

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

Explanations:

Part A:

AB = DE is given at the very top of the problem. So we simply say "given". We always repeat what we are given at the very start of the proof. You can see this for lines 1 through 3, which are repeating the three givens.

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

Part B:

The three givens are:
AB = DE
angle A = angle D
angle B = angle E
the first and last of this trio is used (for statements 1 and 3 respectively). So the only thing left is "angle A = angle D"

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

Part C:

We're using ASA (angle side angle) because we're given two pairs of congruent angles. The side for each triangle is between the two angles. See the attached diagram for more info.

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

Part D:

For any proof, you will ALWAYS have the last statement be the thing you want to prove. In this case, we want to prove BC = EF.

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

Part E:

CPCTC stands for "Corresponding Parts of Congruent Triangles are Congruent"

If the two whole triangles are congruent, then the smaller corresponding parts that make up the triangles must be congruent as well.
