Evaluate the expression −t/u+vw , where t = 2, u=−2/3 , v=−1 , and w=−1/3 .3 1/31 2/3−2 2/3

Answers

Answer:

The answer is 3 1/3

The value of the expression  −t/u+vw is 3 1/3 after pluggin the values of t, u, v, and w in the expression.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that,

The expression is:

= −t/u+vw

The values of t = 2, u=−2/3 , v=−1 , and w=−1/3

After pluggin the values of t, u, v, and w in the above expression we get:

= -2/(-2/3) + (-1)(-1/3)

The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

= 3 + 1/3

= 3 1/3 (in mixed fraction)

Thus, the value of the expression  −t/u+vw is 3 1/3 after pluggin the values of t, u, v, and w in the expression.

Answers

Answer:

Alex spends more time in his homework.

Step-by-step explanation:

To make it easier to compare their homework time on math, convert 2/5 into a percentage: Divide the numerator by the denominator:

Darius: 35%

Alex:  2/5 = 0.40 × 100 = 40%

Seeing both percentages make it easier to determine that Alex spends more time in his homework than Darius.

Answer:

Alex spends more time doing math homework. 2/5 is equal to 4/10 and 4/10 as a decimal is 0.4 which is 40%. 40% is greater than 35% so Alex spends more time than Darius doing math homework.

Marie is reading a 271-page book. She has already read 119 pages. If she reads
at about 8 pages per hour, how long will it take her to finish the book?
Which equation helps to solve this problem?

Answers

Answer:

119+8h=271

Step-by-step explanation:

We already know she has read 119 pages out of 271. And we know the constant proportionality in this is 8 pages every hour. If we were able to find out how long it took for her, then we would add that with 119, because that, in total, will be 271/the whole book, with 152 pages of it in hours.

What is the smallest distance between the origin and a point on the graph of:y=1/sqrt(2)*(x^2-8)

Answers

What we are being asked here is to simply minimize distance. Also, note that we can write
f
(
x
)
=
√
x
as
y
=
√
x
.
Now, what is this "distance?" How do we find it? Well, if you think back to Algebra I or Geometry, you'll remember that the distance between two points
(
x
1
,
y
1
)
and
(
x

is given by:
√
(

. For example, the distance between the points

in our example?
(

is simple - it's just the point given in the problem,
(

. Because we don't know what
x

is, we'll just call it
x
for now. As for
y

, we don't know that either; and since
y
=

Our formula then becomes:

A new drill is used to dig a hole in the ground. At noon, the hole is 13.2 feet deep when the new drill is turned

on for the first time that day. At 2 p.m., the drill has dug the hole to be 42 1/4 feet deep. The new drill dug

1.5 times as much of the hole as the old drill would have in the same length of time.

(a) What expression represents the number of feet the new drill dug?

(b) How many feet would the old drill have dug in the same length of time? Show your work. Answer the
question in a complete sentence.

Answers

Answer:

(a) 42.25 - 13.2

(b)  The old drill would have dug 19.367 ft in the same length of time (2 hours).

Step-by-step explanation:

(a) In the two hours, 12 Noon to 2 p.m., the new drill dug

42.25 - 13.2 =

29.05 feet.  

(b) Let r = the old drill dig rate in units of ft/hour

Then, 1.5r = the new drill dig rate.

So, 1.5r (2 hours) = 29.05, so that

r = (29.05)/(1.5 * 2) = 9.6833333 ... ft/hour.

So, the answer is: 9.683333 ... * 2 = 19.367 ft, rounded to the nearest 1000th.  Thus, the old drill would have dug 19.367 ft in the same length of time (2 hours).  

The required expression and the length of hole are 1.5( 42(¹/₄) - 13.2) and 43.57 feet respectively.

What is Unitary method?

In order to solve a problem for two different values of a quantity, its unit value is first derived. This method is known as unitary method.

The given problem can be solved by unitary method as follows,

(a) The expression that represents the length of hole dug by new drill is given as,

The length of hole dug by old drill in 2 hours is given as,

42(¹/₄) - 13.2

For new drill it is  1.5( 42(¹/₄) - 13.2) feet.

(b) The length of drill dug by old drill is,  

42(¹/₄) - 13.2

=  42.25 - 13.2

=  43.57 feet.

Hence, the expression for hole length by the new drill and the length of hole dug by old drill are given as  1.5( 42(¹/₄) - 13.2) and 43.57 feet respectively.

In the college class, there were 15 students that came to the review class before the test. This was 30% of the students in class. How many students were in the class, altogether?

Answers

Answer:

30 students

Step-by-step explanation:

The 15 students that came were 30% of the class:

30% = 15 students

To find 100%, we can first find 10% by dividing both sides by 3

10% = 3 students

(30% ÷ 3 = 10%, 15 ÷ 3 = 5)

Then, multiply both sides by 10 to get 100%

100% = 30 students

(10% × 10 = 100, 3 × 10 = 30)

-5n

+2

then get all of n to the same side

36 = 9n

isolate the variable

36/9 = 9n/9

4 = n

Answer:

n=4

Step-by-step explanation:

Hi there!

We are given the following equation:

5n + 34 = -2(1-7n)

And we want to solve it for n

To do that, we want to isolate n (also written as 1n) on on side by itself.

In this equation, on the right side, we have -2(1-7n), which is in the way. We'll need to open it up.

In order to open up the parenthesis, we'll need to do the distributive property, where we will multiply -2 to both 1 and -7n, then add them together.

-2(1-7n)=-2+14n

That's for the right side.

The equation now looks like this:

5n + 34 = -2 + 14n

Remember that we will be trying to isolate n on one side

Subtract 5n from both sides to remove it from the left side:

5n + 34 = -2 + 14n

-5n                  -5n

__________________

34 = -2 + 9n

Add 2 to both sides to remove it from the right side:

34 = -2 + 9n

+2    +2

______________

36 = 9n

Now, we have numbers on one side and variables on the other, but we're not done yet, since remember; we want just n (or 1n), not 9n. We need to divide both sides by a number that will result in 1n

If we divide a number by itself, then the result is 1

So we should divide both sides by 9

4 = 1n, also written as 4=n , or n=4

Hope this helps!
