Answer:
Remove the parentheses, use LCM (least common multiplier), adjust fractions based on the LCM, since denominators are equal, combine the fractions, subtract. Your answer would be: -5/12.
Step-by-step explanation:
Steps to the words I said but in fraction step:
3/4 + (-1/2) + (-2/3)
3/4 - 1/2 - 2/3
9/12 - 6/12 - 8/12
9-6-8/12
-5/12
In ΔDEF, the measure of ∠F=90°, the measure of ∠D=70°, and EF = 4.4 feet. Find the length of FD to the nearest tenth of a foot.
Answer:
FD= 1.6 ftStep-by-step explanation:
Seems like an easy trig question so let's get to it.
1) Draw the right triangle to make it easier to solve (right triangle because we have a 90 degree angle)
2) Find the last angle measure by adding 90+70= 160 and 180-160= 20 so the last angle measure is 20.
3) Use trig function, tan20= x/4.4 to find the answer of x (FD) to be 1.6. Therefore, the FD value will be 1.6 ft.

Barkley's team won 40% of their games last season. If they won 12 games total last season, how many games did they play?
Answer:
30 games
Step-by-step explanation:
if they won 12 games which is 40% of their total games played 100% is the number of games played .form an equation...
if 12=40
x=100 cross multiply 12 and 100 then divide by 40 to get x
12×100=1200÷40=30.

plz help with the problem
add it and you will get 24 so pick D
can someone please double check this for me?
Answer:
False
True
False
True
Step-by-step explanation:
The 4th option should be correct because the y-intercept on A is greater than the one in B,
A: y = -1/3x + 0 (usually when the y-intercept ain't appearing it means it's 0).
B: y = -1/3 - 2
As we know 0 is greater than -2 because it's closer to being a positive number, so 0 is not positive or negative; 0 is greater than any negative number but smaller than any positive numer so,
0 > -2.
Therefore the last option is true.

You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %
Answer:
75%
Step-by-step explanation:
You pick a card at random. 6 7 8 9 What is P(not 9)? Write your answer as a percentage. %
Given the following
Total cards = 4 (6,7,8,9)
If the card is not 9, the required card will be (6,7,8)
Number of cards that are not 9 is 3
Probability = expected/total
Pr(not 9) = 3/4
express as percent
Pr(not 9) = 3/4×100
Pr(not 9) = 75%
Answer:
50%
Step-by-step explanation:
There are 4 cards, numbered 6, 7, 8, and 9. The numbers greater than 7 are 8 and 9. There are 2 numbers greater than 7.
P(greater than 7) =
2
4
Write your answer as a decimal. Then convert your answer to a percentage.

The label for a square box of pasta has an area of 16 in? What is the side length of the box?
Answer:
4.
Step-by-step explanation:
A square has four sides of equal length.
And, the formula for area of a square is a^2.
And, 4^2 or 4⋅4 = 16.
Therefore, the side length of the box is 4.

The equation of the function is Y=4x+5.Find the value of y when
x=3
x=-2
The equation of the function is y = 4x + 5. Find the value of y when
x = 3
x = -2
Answer:-Given:-y = 4x + 5 [Equation]
To Find:-The value of y when x = 3 , x = -2
Solution:-y = 4x + 5 [Given equation]
[tex] \therefore [/tex] When x = 3 ,
y = 4 × 3 + 5 [Value of x is 3]
y = 12 + 5
y = 17 [Answer]Again, when x = -2 ,
y = 4 × (-2) + 5 [Value of x is -2]
y = -8 + 5
y = -3 [Answer]Find 2 and 3 please explain how u got ur answer

Step-by-step explanation:
∛8 = 2 as 2*2*2 = 8
[tex]5^{-2}[/tex] = [tex]\frac{1}{5^{2} }[/tex] = [tex]\frac{1}{25}[/tex]
[tex]\frac{1}{25}[/tex] * 2 = [tex]\frac{2}{25}[/tex] = 0.08

A number cube labeled 1 through 6 is rolled once in the spinner shown is spun once. The spinner has four equal sized sections. This experiment is repeated 60 times. The relative frequency for getting a sum of five was 1/5. What is the difference between the number of expected outcomes in the number of actual outcomes?
Answer:
2
Step-by-step explanation:
I did it on Mc Graw Hill
Difference between number of expected outcomes and number of actual outcomes is; 2
What is the number of outcomes?
From the question, we are told that the number cube is labelled from 1 to 6.
This means that there are supposed to be 6 expected outcomes.
However, from the spinner, we see only 4 numbers which are 1, 2, 3 and 4. This means the number of actual outcomes will only be 4.
Thus;
Difference between expected outcome and actual outcome = 6 - 4 = 2

A manager at a factory finds that in a random sample of 250 watches, 3 are defective. Of the 7,500 watches from which the sample was chosen, about how many watches are not defective?
Answer: 7410 watches
Step-by-step explanation:
From the random sample of 250 watches, 3 are defective. The percentage that's defective will be:
= 3/250 × 100
= 1.2%
Percentage that's not defective = 100 - 1.2 = 98.8%
Therefore, from the sample of 7500 watches, the number that's not defective will be:
= 98.8% of 7500
= 98.8/100 × 7500
= 7410
Therefore, 7410 watches aren't defective
