Round off 0.482 to one significant figure

Answers

Answer 1

To round 0.482 to one significant figure, consider the first non-zero digit '4' and round up to '5' because the next digit is '8', giving you 0.5.

To round off the number 0.482 to one significant figure, you look at the first non-zero digit, which is '4' in this case. Since the digit to the right of '4' is '8', which is greater than 5, you round up the '4' to '5'. Therefore, 0.482 rounded to one significant figure is 0.5.

Using examples from provided references:

(a) 0.424 rounds to 0.42 (to two significant figures)(b) 0.0038661 rounds to 0.00387 (to three significant figures)(c) 421.25 rounds to 421.3 (to four significant figures)(d) 28,683.5 rounds to 28,684 (to five significant figures)

7 + z < 3

Can someone help me solve this inequality please?

Answers

7 + z < 3

You solve this the same way you would any other algebraic expression such as..

7 + x = 3.

So, just subtract the seven from the three and you have your answer!

7 + z < 3

7 + z - 7 < 3 - 7

z < -4

The answer is z < -4

To find the answer to an inequality, you treat it just like an equation and try to get the variable by itself. So, to do this we subtract 7 from both sides and we get z < -4

Hope this helped!!! :)

What is standard form

Answers

Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000 . So 4000 can be written as 4 × 10³ . This idea can be used to write even larger numbers down easily in standard form.

Standard form comes in the form of Ax + By = C. In this form, you can easily get the Y intercept and the X intercept. If you want to get the Y intercept, just set x to 0 and solve for Y. And vice versa. If you want to get the slope of the line, one must convert the Standard form formula into the slope intercept form.

what is 2.25 as a fraction

Answers

The answer is 2 1/4 because 0.25 is equal to 1/4. So 1/4 plus 2 is 2 1/4

the first thing to do here is convert it to a mixed number.

.25 should be a somewhat familiar decimal. it's created by the fraction (1/4), so instead of 2.25, you could write this as 2 1/4 (two and one-fourth).

now that you have 2 1/4, convert it to an improper fraction. remember, multiply the bottom of your fraction with the big number out front, then add to the top of your fraction. set it over your denominator.

2 1/4 ... 4*2 is 8, 8 + 1 is 9, and your resulting fraction is (9/4).

___________________________________
→ The unit symbols, "b", cancel to "1"; and we have:
__________________________________

(Simplify both sides of the equation)

Final answer:

The system of linear equations is solved by substitution, resulting in the solution x=-3/5 and y=6.2.

Explanation:

To solve the system of linear equations by substitution, start with the given system:

4x − 2y = 14
y = 12x − 1

Since y is already isolated in the second equation, substitute (12x − 1) for y in the first equation:

4x − 2(12x − 1) = 144x − 24x + 2 = 14−20x + 2 = 14−20x = 12x = −1/20 × 12x = −6/10x = −3/5

Now substitute x = −3/5 into the second equation to find y:

y = 12(−3/5) − 1y = −36/5 − 1y = −7.2 − 1y = 6.2

The solution for the system of equations is x = −3/5, y = 6.2.

Each of the 18 tires of a fully loaded semi truck is bearing approximately 3,300 pounds. The unloaded truck and trailer, with the driver aboard weighs 30,000 pounds. The truck holds 26 pallets of cargo when it is fully loaded. What is the approximate average weight of one pallet of cargo? A. 1,131 lbs
B. 1,280 lbs
C. 1,633 lbs
D. 1,665 lbs

Answers

Process of elimination is helpful here.

Starting with A, if every pallet weighs approximately 1,131 pounds and there are 26 pallets, then that's 29,406 total pounds of additional weight. Add that additional weight to the 30,000 of the truck and trailer and you have 59,406 total pounds. If you divide that number by 18, you get the total number of pounds that each tire is supporting. 59,406 divided by 18 is 3300, so that seems to be the answer.

Answer: A. 1,131 lbs

Step-by-step explanation:

Given: the weight of each tire of a fully loaded semi truck = 3,300 lbs

Then the weight of 18 tires of a fully loaded semi truck = [tex]18\times 3300=59400\ lbs[/tex]

Also, the unloaded truck and trailer, with the driver aboard weighs 30,000 pounds.

Therefore, the weight of pallets = [tex]59400-30000=29400\ lbs[/tex]

Hence, the weight of 26 pallets of cargo when it is fully loaded= 29400 lbs

Now, the weight of each pallet= [tex]\frac{29400}{29}=1130.76923077\approx1131\ lbs[/tex]

∴ The approximate average weight of one pallet of cargo= 1131 lbs

What is the answer 1/2k+6=4k–8

Answers

the answer is 4. ur welcome

Final answer:

To solve the equation 1/2k + 6 = 4k - 8, subtract 1/2k from both sides, combine like terms, add 8 to both sides, combine constant terms, divide by 3.5, and solve for k to get k = 4.

Explanation:

To solve the algebraic equation 1/2k + 6 = 4k - 8, we need to isolate the variable 'k' on one side of the equation. Here are the steps:

Subtract 1/2k from both sides: 6 = 4k - 1/2k - 8.Combine like terms on the right side: 6 = 3.5k - 8.Add 8 to both sides to get all constant terms on the left side: 6 + 8 = 3.5k.Combine the constant terms: 14 = 3.5k.Divide both sides by 3.5 to solve for k: k = 14 / 3.5.Calculate the division: k = 4.

Therefore, the solution to the equation is k = 4.

find the value of x and the measure of angle MNQ

Answers

Since the two angles within MNP equals to 90 degrees: 3X-13+58=90
Isolate X to one side: 3X= 45
Divide by three: X=15
Plug in 15 for X for MNQ (3X-13)= 32 degrees for angle of MNQ.

The angle is given as 3x - 13 and 58. The measure of angle MNQ (3x - 13) is 32 degrees.

What are complementary angles?

Two angles whose sum is 90° are called complementary angles.

The angle is given as 3x - 13 and 58.

Since the two angles within MNP equal to 90 degrees:

3x - 13 + 58 = 90

3x = 90 - 45

3x = 45

x = 15

Therefore, The measure of angle MNQ (3x - 13) = 32 degrees.

At a concert, you purchase 3 T-shirts and a concert program for a total cost of $90.The program for a total cost $15 and the T-shirts all cost the same. Write and solve an equation to find the cost of one T-shirt

Answers

Final answer:

To solve the problem, we created an equation representing the total cost of 3 T-shirts and a program, and then solved it to find the cost of one T-shirt, which is $25.

Explanation:

Let's denote the cost of one T-shirt as 'T'. Since the total cost of 3 T-shirts and a program is $90, and we know that the cost of the program is $15, we can write our equation as follows: 3T + 15 = 90.

To solve for 'T', we start by subtracting 15 from both sides of the equation, getting us 3T = 90 - 15 = 75.

Next, we would divide both sides by 3 to find the cost of one T-shirt. Hence T = 75 / 3 = $25. So, the cost of one T-shirt is $25.

Draw and label a rectangle prism that has a surface area of 158 square yards

Answers

A rectangular prism with dimensions [tex]$8 \times 5 \times 3$[/tex] yards has a surface area of 158 square yards, verified by substituting into the surface area formula.

To draw and label a rectangular prism with a surface area of 158 square yards, we first need to understand the surface area formula for a rectangular prism.

The surface area $A$ of a rectangular prism can be found using the formula:

[tex]\[ A = 2lw + 2lh + 2wh \][/tex]

Where[tex]$l$, $w$, and $h$[/tex] are the length, width, and height of the rectangular prism, respectively.

Given the surface area[tex]$A = 158$[/tex] square yards, we can now find different combinations of [tex]$l$, $w$, and $h$[/tex] that satisfy this equation.

One possible combination is [tex]$l = 8$, $w = 5$, and $h = 3$.[/tex] Let's verify this:

[tex]\[ A = 2lw + 2lh + 2wh \][/tex]

[tex]\[ = 2(8 \times 5) + 2(8 \times 3) + 2(5 \times 3) \][/tex]

[tex]\[ = 2(40) + 2(24) + 2(15) \][/tex]

[tex]\[ = 80 + 48 + 30 \][/tex]

[tex]\[ = 158 \text{ square yards} \][/tex]

Therefore, a rectangular prism with dimensions [tex]$8 \times 5 \times 3$[/tex]yards will have a surface area of 158 square yards.

Now, to draw and label the rectangular prism:

- Draw a rectangular prism with dimensions [tex]$8 \times 5 \times 3$[/tex] yards.

- Label the length[tex]($l$),[/tex] width [tex]($w$),[/tex] and height[tex]($h$)[/tex] accordingly.
