Ed has a recipe that uses [tex]\frac{2}{3}[/tex] cup of flour for each batch. If he makes 4 batches, how many cups of flour will he need? Answer in a fraction pls! Will give brainliest!
Answer:
The formula for this would be [tex]2/3 \times4[/tex]
Since we need to multiply the fraction against the amount of batches, to get the final result of cups of flours. (It only makes sense!)
8/3 is the correct answer
2 2/3 is the mixed fraction
Answer as an improper fraction: 8/3
This converts to the mixed number 2 & 2/3
So he'll need 2 whole cups plus another 2/3 of a cup.
===========================================================
Explanation:
1 batch uses 2/3 of a cup
4 batches uses 4*(2/3) = (4/1)*(2/3) = (4*2)/(1*3) = 8/3 of a cup
Simply multiply 2/3 by 4 to get 8/3.
-----------
If you need to convert to a mixed number, then you could follow these steps
8/3 = (6+2)/3
8/3 = 6/3 + 2/3
8/3 = 2 + 2/3
8/3 = 2 & 2/3
Or you could note that 8/3 = 2.667 approximately. The decimal portion 0.667 converts to the fraction 2/3.

Please answer I will give you a lot of points!!
9514 1404 393
Answer:
7+(7–7) ÷(7+7•7)= 7
Step-by-step explanation:
The difference 7 - 7 provides an opportunity to zero out everything to its right. That's what we've done in this version:
7 +(7 -7) ÷ (7 +7×7) = 7 . . . our version of the equation
7 +0 ÷ (7 +49) = 7 . . . . . multiplication inside parentheses first
7 +0 ÷ 56 = 7 . . . . . . . . parentheses first

An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded.
Answer:
B - 12,111
C - 11,589
Step-by-step explanation:
An ice cream shop has a sign in their window that says, "We sell 12,000 scoops per month." The number of scoops has been rounded. Which could be the number of scoops sold if they rounded to the nearest thousand? Choose all answers that apply: *
A - 10, 999
B - 12,111
C - 11,589
In order to round off to the nearest thousand, look at the hundred figure, if the number is greater or equal to 5, add 1 to the thousand figure. If this is not the case, add zero. Replace all the figures before the thousand figure with zero. i.e. the hundred ten, unit
Rounding off 10,999 to the nearest thousand is 11,000
the hundred figure is greater than 5, so one is added to the thousand figure. The
Rounding off 12,111 to the nearest thousand is 12,000
the hundred figure is less than 5, so zero is added to the thousand figure.
Rounding off 11,589 to the nearest thousand is 12,000
the hundred figure is equal to 5, so one is added to the thousand figure.
Find the product of (x-2) and (3x^2-4x-5)
Answer:
3x³ - 10x² + 3x + 10
Step-by-step explanation:
multiply 'x' by each term in the second expression:
(x-2)(3x²-4x-5) = 3x³ -4x² - 5x
now multiply '-2' by each term in the second expression:
-6x² + 8x + 10
combine 'like' terms: -4x² + (-6x²) to get -10x²
combine 'like' terms: 8x - 5x = 3x
answer: 3x³ - 10x² + 3x + 10

A medical test has a 95% accuracy of detecting a Condition Z if the person has it. It also has a 97% chance to indicate that the person does not have the condition if they really don't have it. If the incidence rate of this disease is 10 out of every 100: What is the probability that a person chosen at random will both test positive and actually have the disease (i.e., get a true positive)
Answer:
0.77
Step-by-step explanation:
According to the Question,
Let, We have 10000 patients & If the incidence rate is 10 out of 100, then 1000 people will have the disease.
Given, A medical test has a 95% accuracy of detecting Condition Z if the person has it. Thus, Out of those 1000, 950 will test positive.And, It also has a 97% chance to indicate that the person does not have the condition if they really don't have itSo, Out of the 9000 people who don't have the disease, 3%
that is, 270 People, will get a false positive.
Thus, the probability that a person is chosen at random will both test positive and actually have the disease is [tex]\frac{950}{950+270}[/tex] .
[tex]\frac{950}{1220}[/tex] ⇒ 0.7786 ≈ 0.77how many miles from the runaway airplane at the start of this approach.

Refer to the attachment for step by step explaination.
Have a nice day!!
Answer:
[tex]p = \frac{2 - 3g}{(g + 4)} [/tex]
Step-by-step explanation:
[tex]g = \frac{2 - 4p}{3 + p} \\ g(3 + p) = 2 - 4p \\ 3g + pg = 2 - 4p \\ pg + 4p = 2 - 3g \\ p(g + 4) = 2 - 3g \\ \frac{p(g + 4)}{(g + 4)} = \frac{2 - 3g}{(g + 4)} \\ p = \frac{2 - 3g}{(g + 4)} [/tex]

Eight expressions are given below. Determine whether each expression is equivalent to 5^10 or not equivalent to 5^10.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the 8 expressions are not given.
The general explanation is as follows
As complex as an expression may seem, you have to simplify each expression until it cannot be further simplified.
Then you categorize each result, depending on if it equals [tex]5^{10}[/tex] or not
Take for instance:
[tex]5^5 * 5^5[/tex]
Using law of indices:
[tex]5^5 * 5^5 = 5^{5+5[/tex]
[tex]5^5 * 5^5 = 5^{10[/tex] ---- equivalent
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}}[/tex]
Factorize the numerator
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5(1 + 1)}{2 * 5^{-5}}[/tex]
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5 * 2}{2 * 5^{-5}}[/tex]
Cancel out 2
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = \frac{5^5}{5^{-5}}[/tex]
Apply law of indices
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5--5}[/tex]
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{5+5}[/tex]
[tex]\frac{5^5 + 5^5}{2 * 5^{-5}} = 5^{10[/tex] ---equivalent
[tex]125 * 78125[/tex]
Express as exponent
[tex]125 * 78125 = 5^3 * 5^7[/tex]
Apply law of indices
[tex]125 * 78125 = 5^{3+7[/tex]
[tex]125 * 78125 = 5^{10[/tex] ---- equivalent
[tex]5^3 + 5^7[/tex]
Solve exponents
[tex]5^3 + 5^7 = 125 + 78125[/tex]
[tex]5^3 + 5^7 = 78250[/tex] ---- not equivalent
