A scale measures weight to the nearest 0.5 pound. Which measurement
shows an appropriate level of precision for the scale?
A. 140 pounds
B. 140.5 pounds
C. 140.75 pounds
O D. 141 pounds

Answers

Answer:

i think B... don't take my word though im not 100% cause it seems way too obvious on what the answer is lol

The measurement shows an appropriate level of precision for the scale is 140.5 pounds.

What is a place value?

Place value, which is related to a digit's location in a number, is the amount that each digit is worth.

The scale measures weight to the nearest 0.5 pounds. This means that the scale can accurately measure weights that end in 0.5 or 0, and it rounds other weights to the nearest 0.5.

Among the given options, the weight that shows an appropriate level of precision for the scale is option B, 140.5 pounds.

This weight can be accurately measured by the scale and is reported to the nearest 0.5 pounds.

Option A, 140 pounds, may be rounded up or down depending on the actual weight and may not be an accurate measurement.

Option C, 140.75 pounds, is too precise for the scale to measure accurately to the nearest 0.5 pounds.

Option D, 141 pounds, is rounded up from 140.5 pounds and may not be an accurate measurement for the scale.

Therefore, 140.5 pounds.

8 t-shirts and a hat costs £42.00
3 t-shirts and a hat costs £17.00.
How much does a t-shirt cost?
How much does a hat cost

Answers

Answer:

a T-shirt costs £5

a hat costs £2

Step-by-step explanation:

Suppose

A T-shirt=x

A Hat=y

So the equation is

8x+y=42

3x+y=17

So

8x+y=42

3x+y=17

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

5x=25

x=5

So a T-shirt costs £5

3.5+y=17

15+y=17

y=2

So a hat costs £2

Answer:

t-shirt: £5

hat: £2

Which boat was farther from the dock at the beginning and which traveled more quickly

Answers

Answer:

Nvm

Step-by-step explanation:

Johns boat was 30 miles away. It traveled 20 miles in 5 hours (50-30 = 20)

20/5 = 4

It traveled at 4 miles per hour.

The equation for Roberta’s boat multiplied 5 by x( number of hours) so this means her boat is traveling at 5 miles per hour.

Then 25 gets added at the end, this means her boat was 25 miles away at the beginning.

Johns boat was further away at the beginning and Robertas boat is traveling faster.

find x and y multiple choice​

Answers

Answer:

x=30

y=4

Step-by-step explanation:

Since there is an equilateral triangle, those angles =60°, and all sides to that triangle are equal.

You can determine y by looking at the congruent lines on the second triangle. In this triangle, we see that two sides, one of which is a side to the equilateral triangle, are equal to 20. Because one of these sides is a side to the equilateral, we know that all sides of the equilateral triangle are equal to 20, so using simple algebra you can determine that y=4.

To solve for x is a little more difficult. In the equilateral triangle, we know that all angles =60°, therefore we can solve for two angles to use to solve for x. We can solve for the obtuse angle by subtracting 60 from 180=120. then we can solve for the next angle that is next to the equilateral triangle because these two make a right angle so 90-60=30. Now you add the angles you just solved for, subtract that sum from 180, and you get x.

120+30=150

180-150=30

x=30

The coordinates of F(x,y) is (5,-4) with midpoint of EF is M(1,-1)

What is midpoint of line segment?

The midpoint divides the line segment into two equal parts. As the number line progresses, the leftmost numbers become smaller, and the rightmost numbers become larger. Adding, subtracting, and multiplying can also be done using a number line like for addition move towards right and for subtraction move towards left.

Here, the mid point of line EF is M with coordinates (1,-1) with coordinates  of E(-3,2) therefore, using mid point formula to find coordinates of F(x,y)

[tex]\begin{aligned}\frac{-3+x}{2}&=1\\x&=2+3\\&=5\end{aligned}[/tex]

and for y coordinates of F :

[tex]\begin{aligned}\frac{2+y}{2}&=-1\\y&=-2-2\\&=-4\end{aligned}[/tex]

Therefore, the coordinates of F(x,y) is (5,-4) with midpoint of EF is M(1,-1)

What do the words coefficient and constant mean in mathematics?

Answers

Answer:

Step-by-step explanation:

Coefficients are the numbers that come BEFORE a variable, just as 55 is in the term 55x. Constants are numbers in an equation that never change, unless you add them with another constant. For example, in the equation 34x+55=24, the constants are 55 and 24. The only way that either changes is by subtracting the 55 from the 24.

coefficients are the numbers before a variable (e. 4b) and constants are numbers that say the same, or numbers wo a variable (e. 4)

Answers

Step-by-step explanation:

(Ax² + Bx + C)²

= (Ax² + Bx + C)(Ax² + Bx + C)

= Ax⁴ + 2ABx³ + 2ACx² + 2BCx + C².

By Comparing Coefficients, we have:

A = 1

2AB = 6

2AC = 7

2BC = a

C² = b

Solving them we get A = 1, B = 3 and C = 3.5.

Therefore a = 2BC = 2(3)(3.5) = 21,

b = C² = (3.5)² = 12.25.

So if a video that is 15:34 how long is it when 2 times speed

tip: times 15 min. buy 60 then divdie all of the sec. by 2

Answers

Answer:

7:47

Step-by-step explanation:

Here are two ways of solving this:

The video will be half the time of 15:34, so you need to divide the time 15:34 by 2.

Method 1)

Use the tip. The video is 15 minutes and 34 seconds long.

Convert minutes to seconds: 15 * 60 = 900

Add 34 seconds to the 15 minutes: 900 seconds + 34 seconds = 934 seconds

The video is 934 seconds long.

Divide the total seconds by 2: 934/2 = 467

467 seconds = 420 seconds + 47 seconds = 7 minutes and 47 seconds

Answer: 7:47

Method 2)

Divide the minutes by 2 and divide the seconds by 2.

15 minutes and 34 seconds.

Divide minutes by 2: 15/2 = 7.5

Divide seconds by 2: 34/2 = 17

Now we need to add 7.5 minutes and 34 seconds.

0.5 minutes is half a minute, so it's 30 seconds.

7.5 minutes + 17 seconds =

= 7 minutes + 0.5 minute + 17 seconds

= 7 minutes + 30 seconds + 17 seconds

= 7 minutes + 47 seconds

= 7:47

A rectangular monitor’s size is measured diagonally from 1 corner to the opposite corner. What is the size of a rectangular monitor that is 30 centimeters wide by 24 centimeters high, to the nearest centimeter?

Answers

Answer:

38cm

Step-by-step explanation:

Using the Pythagorean Theorem, it is found that the size of the monitor is of 38 centimetres.

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

In a right triangle with legs [tex]l_1[/tex] and [tex]l_2[/tex] and hypotenuse h, these measures are related by the Pythagorean Theorem, given by:

[tex]h^2 = l_1^2 + l_2^2[/tex]

In this problem:

The diagonal of the rectangle, which is the size of the monitor, is the hypotenuse.The width of [tex]w = 30[/tex] and the length of [tex]l = 24[/tex] are the legs, thus:

[tex]s^2 = l^2 + w^2[/tex]

[tex]s^2 = 24^2 + 30^2[/tex]

[tex]s = \sqrt{24^2 + 30^2}[/tex]

[tex]s = 38[/tex]

The size of the monitor is of 38 centimetres.
