Answer:
-20
Step-by-step explanation:
let x be the whole. 2/5 of x = -8 so -8 1/5 is -4. -4*5 to find the whole so its -20
Answer: The number is 35
If 2/5 of a number is 14, then we will perform a function of cross multiplication in order to determine the missing number.
Step-by-step explanation:
Let the missing number = y
To perform a cross multiplication, firstly, we multiply the numerator of first fraction by the denominator of the second fraction.
Secondly, we multiply the denominator of the first fraction by the numerator of the second fraction. Then, the resulting values are divided by each other to get a final numerical value.
Therefore, the missing number (y) will the denominator of the second fraction i.e. 14/y . The first fraction is 2/5.
Thus,
2/5 of 14/y
2/5= 14/y
(2 x y) = (5 x 14)
(2y) = (70)
2y = 70
Since we are looking for value of y, divide both sides by the value beside y
Thus,
2y/2 = 70/2
y = 35
Therefore, the missing number is 35

Answer:
The diffrence is that 4 3/4 is greater then 3 1/2 because if you take 4 by itself by 3 then 4 will 4 because the whole number is greater so their for the intier answer will be greater. 3 1/2 is less then 4 3/4 because the whole number is lower so their for the answer is less.

Step-by-step explanation:
find the distance between C(5,-6) and D(5,6)
Answer:
the distance is 12 units
Step-by-step explanation:
5 and 5 are the same so we don't use those digits,
-6 and 6 are different so we use them
since - 6 and 6 are both in different quadrants we take the absolute value of both of them and add,
|-6| + |6| = |6| + |6| = 12,
therefore the distance between C: (5,-6) and D: (5,6) is 12 units. hope i helped you (and could i have brainliest if possible?)
===========================================================
Explanation:
The x coordinates are the same (both are 5), so we just focus on the y coordinates.
The y coordinates are y = -6 and y = 6. Subtract the two values and apply absolute value to find the distance. Let's say A = -6 and B = 6.
|A-B| = |-6-6| = |-12| = 12
or we could say
|B-A| = |6-(-6)| = |6+6| = |12| = 12
Either way, we get the same answer. The order of subtraction doesn't matter if we apply absolute value.
On a graph, plotting the two points (5,-6) and (5,6) will show that there's 12 units of space between them.
--------------
If you wanted, you could apply the distance formula like so:
(x1,y1) = (5,-6)
(x2,y2) = (5,6)
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(5-5)^2 + (-6-6)^2}\\\\d = \sqrt{(0)^2 + (-12)^2}\\\\d = \sqrt{0 + 144}\\\\d = \sqrt{144}\\\\d = 12\\\\[/tex]
Though in my opinion, I think the distance formula is overkill for this situation.

US Weekly magazine claims that 32% of its readers believe Angelina Jolie was best dressed at the Academy awards. To verify this claim, how large a sample is needed for a 0.05 margin of error at a 95% confidence level?
Answer: 335
Step-by-step explanation:
Formula for sample size :
[tex]n=p(1-p)(\dfrac{z^*}{E})^2[/tex], where p =population proportion, z* = critical z-value, E = Margin of error.
Given: p = 32% = 0.32
E = 0.05
Critical z-value for 95% confidence = 1.96
Required sample size :
[tex]n=(0.32)(1-0.32)(\dfrac{1.96}{0.05})^2\\\\=334.372864\approx335[/tex]
Hence, the required sample size = 335

Two hundred dollars is increased by 25% and the result decreased by 25%
What is the final result?
Answer:
If $200 increased by 25%, your result would be $250
If it then decreased by 25%, your result would be $187.5
Step-by-step explanation:
Multiply 200 and 25% and add 200 to get 250
Multiply 250 and 25% and then add that value to get 187.5
Answer:
187.5
Step-by-step explanation:
200*1.25=250 (this shows the increase by 25%)
250*.75=187.5 (this shows the decrease by 25%)

A sofa with an original price of $600 is put on sale for $480.
What is the percentage discount on the cost of the sofa?
Answer:
20%
Step-by-step explanation:
Percentage discount on the cost of the sofa = 20%
What is percentage discount?Percentage discount = (Absolute discount / Cost price) × 100
Given,
Cost price = $600
Absolute discount = Cost price - Selling price
Absolute discount = $600 - $480
= $120
Percentage discount = (Absolute discount / Cost price) × 100
= (120/600) × 100
= 120/6
= 20%
Hence, percentage discount on the cost of the sofa = 20% .

What is Triangle?
A triangle is a three sided polygon , which has three vertices.
Given that;
In ΔEFG,
EG is extended through point G to point H.
m ∠EFG = (2x + 1)°
m ∠FGH = (6x + 2)°
m ∠GEF = (x + 19)°
Here, m ∠FGH is an exterior angle of ΔEFG.
And, m ∠EFG and m ∠GEF are interior angles of ΔEFG.
Since, Sum of two interior angle is equal to the value of an exterior angle.
Hence, We can formulate;
(2x + 1)° + (x + 19)° = (6x + 2)°
Solve as;
2x + 1 + x + 19 = 6x + 2
3x + 20 = 6x + 2
Subtract 3x both side;
3x + 20 - 3x = 6x + 2 - 3x
20 = 3x + 2
3x + 2 = 20
Subtract 2 both side;
3x + 2 - 2 = 20 - 2
3x = 18
Divide by 3;
x = 6
Thus, Value of m ∠GEF = (x + 19)° = (6 + 19)° = 25°
Therefore, The measure of angle GEF is 25°.
