An English teacher reviewed 2 3 of an essay in 1 4 of an hour. At this rate, how many essays can she review in 1 hour?

Pls help me I've spent like an hour on this now

Answer:

Hi there! Your answer is =4 3/4

Step-by-step explanation:

I hope this helps :]

Alright. First I did 1/4 + 1/6. I got 5 1/2

Then I did 5 1/2 + -3/4. Because it is negitive I had to go down so that is why it is lower. if you need a more detailed explanation ill gladly tell you!

1/4+1/6=?

Find the LCD of 1/4 and 1/6 and rewrite to solve with the equivalent fractions.

CD = 12

3 1 /2+2 1/2=5 1/2

Solution by Formulas

Using the given fractions,

1/4+1/6

Applying the fractions formula for addition,

=(1×6)+(1×4)4×6

=6+4 2/4

=10 2/4

Simplifying 10/24, the answer is

=5 1/2L

if you want the other one tell me!

Answer:

5/6

The correct representation of the given equation 6x7=42 in words is that 42 is 6 times as many 7.

Step-by-step explanation:

This is because, the product of 6 and 7 is 42. So, we sya 6 time 7 is 42 or 7 times 6 isi 42 means one and the same thing.

Answer:

6x7=42.

Step-by-step explanation:

7 is 6 times as many as 42 or 6 is 7 times as many as 42 or 42 is 6 times as many 7.

Answer:

the answer is 4 1/2

Step-by-step explanation:

first you have to turn your 2 1/7 into an improper fraction :  2x1+7, and you get 9/7.

then you divide 9/7 by 2/7 or you can also flip the second fraction and multiply : 9/7 divided by 2/7 turns into --- 9/7 x 7/2 so from here you cross simplify, you cant simplify 2 into 9 so no simplifying there but 7 can go into 7 once so you are left with 9/1 and 1/2 then multiply 9x1 and 1x2 and you get 9/2.

from here you turn your improper fraction into a proper fraction by seeing how many times 2 can go into 9 , which is 4 times (4 is the whole numbers) and you are left with 1 (numerator) over 2 (denominator)

The side ED is a midsegment of the triangle ΔABC, therefore, the length of

ED is half the length of AB.

[tex]\displaystyle The \ expression \ that \ represent \ the \ value \ of \ s \ is; \ s = \frac{1}{2} \cdot u[/tex]

Reasons:

The given parameters are;

In ΔABC, point E is the midpoint of AC

The midpoint of BC is the point D

Segment ED = s

Segment CE = p

Segment EA = r

Segment CD = q

Segment DB = t

Segment ED = s

Segment AB = u

Required;

The expression that represents the value of s

Solution:

CE = 0.5 × AC Definition of midpoint

CD = 0.5 × CB Definition of midpoint

Therefore;

Therefore, we have;

[tex]\displaystyle \frac{CE}{AC} = \mathbf{\frac{CD}{CB}} = 0.5[/tex]

Therefore, given that ∠C ≅ ∠C, by reflexive property, we have;

ΔABC is similar to ΔCDE by Side-Angle-Side similarity

Which gives;

[tex]\displaystyle \frac{CE}{AC} = \frac{CD}{CB} = \mathbf{\frac{ED}{AB} } = 0.5 = \frac{1}{2}[/tex]

ED = s and AB = u which gives;

[tex]\displaystyle \frac{ED}{AB} =\frac{s}{u} = 0.5 = \frac{1}{2}[/tex]

[tex]\displaystyle \frac{s}{u} = \frac{1}{2}[/tex]

Which gives;

[tex]\displaystyle s = \mathbf{ \frac{1}{2} \times u}[/tex]

(The above relationship is given by the midsegment theorem)

Therefore;

The expression that represents the value of s is; s = one half u

Answer:

b. 31/3..................

The student needs 16.3 packages of clay to complete his project

Data given;

To solve this question, we just need to divide fractions.

This is done when the denominator divides the numerator. Often times, this also results in multiplication

To get the number of package the student needs, let's write an equation

[tex]2/3 = 1/8x[/tex]

where x = number of packages needed

[tex]\frac{2}{3} = \frac{1}{8}x\\ 2 * 8 = 3 * x\\ 16 =3x\\x = 16/3\\[/tex]
