Answers

Answer 1

Answer:

Step-by-step explanation:

It is given that A rectangular prism has a length of [tex]1\frac{1}{4}[/tex]yards a width of [tex]2\frac{1}{2}[/tex] yards, and a height of 4 yards.

Now, the volume of the prism is given as:

[tex]V=Length{\times}width{\times}height[/tex]

[tex]V=\frac{5}{4}{\times}\frac{5}{2}{\times}4[/tex]

[tex]V=\frac{25}{2}[/tex]

[tex]V=12\frac{1}{2}cubic yards[/tex]

Therefore, the volume of the rectangular prism will be [tex]V=12\frac{1}{2}cubic yards[/tex].

What number could be added to 0.40 mL for the level of precision to be 0.01mL

Answers

Answer:

- 0.39

Step-by-step explanation:

Level of precision = 0.01 mL

We need to find a number which could be added to 0.40 mL for the level of precision to be 0.01 mL .

Let x be a number  which could be added to 0.40 mL for the level of precision to be 0.01 mL .

[tex]x+0.40=0.01[/tex]

On subtracting 0.40 from both sides , we get

[tex]x+0.40-0.40=0.01-0.40[/tex]

On solving , we get

[tex]x+0=0.01-0.40[/tex]

We know that [tex]x+0=x=0+x[/tex] where 0 is the additive inverse .

So,

[tex]x=0.01-0.40[/tex]

Here , [tex]0.01-0.40=-0.39[/tex]

Therefore ,

[tex]x=0.01-0.40=-0.39[/tex]

Therefore , -0.39 could be added to 0.40 mL for the level of precision to be 0.01mL

No, because that would mean that she is spending about $13.85 on 1 message per month. That is ridiculous lol.

Jessica has the option to switch to a plan that charges $65.00 per month with unlimited text messages.

Jessica typically sends about 900 text messages per month.

Cost per message under the new plan = $65 / 900 = $ 0.072 per message

Isolate the p

divide 10 from both sides

Wesley walked 11 miles in 4 hours if he walked the same distance every hour , how far did he walk in one hour

Answers

You would multiply 11 by 4 because he walked 11 miles for every hour so your answer is 44

Wesley walked 2.75 miles in one hour, calculated by dividing the total distance (11 miles) by the total time (4 hours).

The question asks how far Wesley walked in one hour if he walked 11 miles in 4 hours at a consistent pace. To find this, we can calculate his average speed by dividing the total distance by the total time. This gives us an equation: Average speed = Total distance / Total time, which simplifies to: Average speed = 11 miles / 4 hours.

Performing the division, we get an average speed of 2.75 miles per hour. Therefore, Wesley walked 2.75 miles in one hour.

dennis wants to buy a card for his wife. dennis calculates the amount of the card as $4.50. the actual price of the card is $4. what is Dennis's percent error?

Answers

First, calculate the error by subtracting the actual price from the estimated price. So the error is $4.50 - $4 = $.50. 
To find the percent error, divide the error by the actual price and multiply by 100 %. Hence, $.50/$4 =.125 x 100 = 12.5 %.
Dennis' percent error is 12.5 %.

Final answer:

Dennis's percent error in estimating the price of the card is 12.5%, calculated by taking the difference between his estimate and the actual price, dividing by the actual price, and then multiplying by 100.

Explanation:

Dennis calculated the amount of the card as $4.50, but the actual price is $4.00. To find Dennis's percent error, we'll need to calculate the difference between his estimated price and the actual price, and then divide that by the actual price. Finally, we'll multiply that number by 100 to get the percent error.

Here's how we'll calculate it:

Divide the error by the actual value: $0.50 ÷ $4.00 = 0.125.

Multiply by 100 to convert to a percentage: 0.125 × 100 = 12.5%.

The percent error in Dennis's estimate is 12.5%.

Why is subtracting an expression similar to distributing -1? Explain.

Answers

Take the expression 2x - (x - 3).  We know we can multiply everything by 1 and not change it; we know that if a variable does not have a coefficient with it, we can write a 1 beside it.  That means we can write our expression as
2x - 1(x - 3).  This helps us see the distributive property applies here:
2x - 1x - 1(-3)
2x - 1x - -3
2x - 1x + 3
1x + 3 = x + 3

Subtracting an expression is akin to distributing -1 to each term within the expression. This is because subtraction can be viewed as adding the negation of the expression, which involves multiplying each term by -1. So, each term within the expression gets negated when subtracting.

When you subtract an expression, you can think of it as distributing a negative sign (-1) to each term within the expression. Here's a step-by-step explanation:

Start with the expression you want to subtract from, let's call it A.

When you subtract another expression, let's call it B, from A, you're essentially adding the negation of B to A.

The negation of B is obtained by multiplying each term of B by -1.

Distributing -1 to each term of B results in subtracting each term of B individually from A.

This process aligns with the distributive property, making subtracting an expression akin to distributing -1 to each term within the expression.

Best of luck my friend. :)

A linear equation of one variable is expressed in the form of ax + b = 0, where a and b are the two integers, and x is a variable.

In the given question, the linear equation can be represented as:

2x + 10 + x = 73.

The number of dogs is 21, and the number of cats available is 52.

Given that:

Total number of dogs and cats = 73

Let the number of dogs be x.

The number of cats, as given is = 10 + 2x

Now, solving for the equation:

x + 10 + 2x  = 73

Solving for the variables:

3x + 10 = 73

3x = 73 -10

3x  = 63

x = [tex]\dfrac {63}{3}[/tex]

x = 21

The number of dogs available is 21.

The number of cats available is:

2x + 10

Putting the value of x:

2 (21) + 10

52

Thus, the number of dogs is 21, and the number of cats available is 52.

First, find the area of the triangle:

The formula of the area of a triangle, "A":

A = (1/2) * b * h ; 

in which:  " A = area (in units 'squared') ;  in our case, " yd² " ; 

                 " b = base length" = 6 yd.  

                 " h = perpendicular height" = "(4 yd + 4 yd)" = 8 yd.
___________________________________________________
→  A = (1/2) * b * h = (1/2) * (6 yd) * (8 yd) = (1/2) * (6) * (8) * (yd²) ; 
                                                                 
                                                                   =  " 24 yd² " .
___________________________________________________
Now, find the area, "A", of the square:

The formula for the area, "A" of a square:

   A = s² ;

in which:  "A = area (in "units squared") ; in our case, " yd² " ;
                 
                 "s = side length (since a 'square' has all FOUR (4) equal side lengths);

 A = s²  = (4 yd)² = 4² * yd² =  "16 yd² "
