Sharon is painting her house. she needs 5
gallons of brown paint for every 7 gallons of white paint. How many gallons of white paint does she need if she already bought 14 gallons of brown paint?
A. 10 gallons
B. 19.6 gallons
C. 16 gallons
D. 25 gallons
Answer:
19.6, B
Step-by-step explanation:
To solve, we need to figure out how many gallons of white paint she needs for every gallon of brown paint.
We are given this equation.
5 gallons of brown paint = 7 gallons of white paint
Divide both sides by 5.
1 gallon of brown paint = 7/5 gallons of white paint = 1.4 gallons of white paint
Now, using this, substitute 14 into the left side.
14 gallons of brown paint = 1.4 * 14 gallons of white paint
14 gallons of brown paint = 19.6 gallons of white paint
Thus, the answer is B, 19.6 gallons
Find the measure of the indicated angle x
Answer:
36°
Step-by-step explanation:
all the interior angles of a triangle add up to 180°
78 + 66 = 144
180 - 144 = 36°
Answer:
sum of all the sides of a triangle= 180° 78°+66°+x = 180° x = 180° - (78° + 66°) = 180° - 144° = 36° x = 36°Ans. = the value of x is 36°.What is an angle that is adjacent to

Which set of ordered pairs is a function? {(1,1),(2, 2), (3, 3), (4,4), (5,5)} {(0,0),(1,1),(1, -1),(4,2),(4, -2)} {(2,1),(2,2).(2,3),(2,4),(2,5)} {(1,5).(2.4),(3,3).(2, 2), (1,1)
[tex] \underline{ \underline{ \large{ \red{ \tt{✧ E\: X \: P \: L \: A \: N \: A \: T\: I \:O\: N}}}}} : [/tex]
❀ Here, We are given relation from A to B [ Suppose ] & We have to identify whether they are function or not from the relation A to B.
{ ( 1 , 1 ) , (2 , 2 ) , ( 3 , 3 ) , (4 , 4 ) , ( 5 , 5 )}⇢ This is a function from A to B because every element of Set A has unique image in set B.
{( 0,0 ) , ( 1 , 1 ) , ( 1 , -1 ) , ( 4 , 2 ) , ( 4 , -2 ) }⇢ This is not a function because two of the elements of Set A ( 1 & 4 ) are associated to elements -1 , 1 & 2 , -2 respectively of Set B
{ ( 2 , 1 ) , (2 , 2 ) , (2 , 3 ) , (2 , 4 ) , (2 , 5 )⇢ This is not a function because the element of Set A ( 2 ) is associated to all the elements of Set B.
{ ( 1 , 5 ) , ( 2 , 4 ) , ( 3 , 3 ) , (2 , 2 ) , ( 1 , 1 )⇢ This is not a function because the elements of Set A ( 1 & 2 ) are associated to elements ( 5 , 1 & 4 , 2 ) of Set B respectively.
[tex] \boxed{ \boxed{ \large{ \purple{ \tt{A \: N \: S \: W \: E \: R: \{ ( 1 , 1 ) , (2 , 2 ) , ( 3 , 3 ) , (4 , 4 ) , ( 5 , 5 ) \} }}}}}[/tex]
♨ Q. What is function ? How can we identify whether the given relation is a function ?
⟶Function is a special type of relation. Function is the refinement of relation. In a relation from A to B , every element of Set A has only one ( distinct ) image in B. In other words , if no two different ordered pairs have the same first component , then it is a function.

Ross has a plan to increase the number of sit-ups he does by the same percent each
week. The table shows his goal for each week of the plan.
Which expression gives the goal for the 52nd week?
Answer:
20•2^51
Step-by-step explanation:
The expression that gives the goal for the 52nd week is 20(2)⁵¹.
Week 1 2 3 4 5
Goals 20 40 80 160 320
This means the numbers are goals are increasing geometrically.
What is a geometric progression?A geometric progression is a series in which any element after the first is obtained by multiplying the preceding element by a constant called the common ratio.
We know the nth term of a GP = arⁿ⁻¹
Where a is the first term and r is the common ratio.
In our problem, a=20 and r=40/20=2
So, the 52nd term of the GP = 20(2)⁵²⁻¹
The 52nd term of the GP =20(2)⁵¹
Hence, the expression that gives the goal for the 52nd week is 20(2)⁵¹.

A math teacher at George Washington Middle School asked boys in the 6th and 7th grades to report their shoe size. She used the results to create these histograms
Which conclusion best supported by the histograms?
A as boys get older, shoe sizes become more normally distributed with fewer large outliers.
B As boys get older, shoe size range, defined by the minimum and maximum, decreases
C As boys get older, shoe sizes increase and the distribution remains relatively unchanged.
D As boys get older, shoe size distribution becomes more spread with more large outliers
Answer:
As boys gets older, shoe sizes becomes more normally distributed with fewer large outliers.
Step-by-step explanation:
A visual analysi ls of the histogram distribution provided, we can observe that size distribution of 6 graders is positively skewed (right tailed) as outliers seems more to the right(large sizes). However, the second graph is balanced with a normal or symmetric distribution representing older age (7th graders). Hence, we can conclude that as the boys gets older, they attain normality in terms of their shoe sizes. And the outliers which are characterized by the first histogram having vanished or reduced.

A number cube labeled 1 through 6 rolled three times. What is the probability that the first roll is a 1, the second roll is a 2, and the third roll is greater than 4?
Answer:
about 2/216 or 1/108
Step-by-step explanation:
the probability of it rolling 1 is 1/6. The probability of it rolling a 2 is 1/6. 1/6 times 1/6 is 1/36. the probability of it rolling a number greater than 4 is 2/6 since 5 and 6 are greater than 4. 1/36 times 2/6 is 2/216. Simplified is 1/108

Answer:
12.207
Step-by-step explanation:
a^2 + b^2 = c^2
a and b are legs of the right triangle, c is the hypotenuse.
The hypotenuse squared is equal to the square root of (7^2 + 10^2).
The square root of 149 is around 12.207.
You cannot simplify the square root of 149 so if the question wants it in radical form just input square root of 149.
