Which expression is represented by the phrase "the square of y decreased by the quotient of 28 and 7"? * 1 point
Answer:
y² - 4
Step-by-step explanation:
Give the expression :
"the square of y decreased by the quotient of 28 and 7"?
Expressing Mathematically ;
Square of y = y²
Quotient of 28 and 7 is obtained by taking the division of 28 by 7
Dividing 28 by 7 ; 28/7 = 4
Hence, decreasing y² by 4 ; we have ;
y² - 4

x = ±√13x = ±3√6x = ±√66x = 0 or 8Step-by-step explanation:
As in any "solve for" situation, you "undo" what is done to the variable.
Here, (for 3 of the 4 problems) the variable is ...
squaredmultiplied by a constantadded to a constantWe undo these operations in reverse order. First, we add the opposite of the added constant. Then we divide by the coefficient of x². Finally, we take the square root to "undo" the squaring operation.
1. 4x² -30 = 22 . . . . . . given
4x² = 52 . . . . . . . . . add 30 to both sides
x² = 13 . . . . . . . . . . . divide both sides by 4
x = ±√13 . . . . . . . . . take the square root. Both signs are solutions.
__
2. 3x² +4 = 166 . . . . . given
3x² = 162 . . . . . . . . add -4 to both sides
x² = 54 . . . . . . . . . . divide both sides by 3
x = ±√54 . . . . . . . . take the square root. 54 = 3²·6 has a square factor
x = ±3√6 . . . . . . . simplified result
__
3. (1/3)x² +14 = 36 . . . . given
(1/3)x² = 22 . . . . . . . . add -14 to both sides
x² = 66 . . . . . . . . . . . multiply both sides by 3
x = ±√66 . . . . . . . . take the square root
__
4. The same "undo" idea applies. Here, we can start with the square root.
(x -4)² = 16 . . . . . given
x -4 = ±4 . . . . . . . square root
x = 4 ± 4 . . . . . . add 4 to both sides
This means x = 4-4 = 0, or x = 4+4 = 8.
The solutions are x = 0, x = 8.

Maxie wrote 75%= 3/5 Bernice wrote 0.05=50%
Lee Ann wrote 3/8=0.375 which students wrote a correct equation?
Answer:
Answer is Lee Ann wrote the right equation.
Step-by-step explanation:
2/8 equals 25%, which equals 1/4, half of 25% is 12.5%, so 25% plus 12.5% equals 37.5%.
37.5% in decimal form is 0.375.
Therefore Lee Ann is correct.

The Barnes family has a coupon for 10% off their dinner. If their bill comes to $82.50 and they wish to tip 15%, what will they pay in total?
Answer:
Total cost= $86.25
Step-by-step explanation:
Giving the following information:
Discount= 10%
Nill= $82.5
Tip= 15%
First, we need to calculate the discounted price:
Discount price= 82.5 / 1.1= $75
Now, the tip:
Tip= 75*0.15= $11.25
Finally, the total cost:
Total cost= 75 + 11.25
Total cost= $86.25

(-3,-1)2
A. y=-3x+1
B. y--3x+3
C. y = 2 x -
D. y-22 8x-3
Answer:
y = -2/3x - 3

Lois and clark own a company that sells wagons. The amount they pay each of their employees (in dollars) is given by the expression 12h+30w where h is the number of hours and w is the number of wagons sold. What is the amount paid to an employee that works 6 hours abs sells 3 wagons?
Answer:
$162
Step-by-step explanation:
Given that,
The amount they pay each of their employees (in dollars) is given by the expression 12h+30w where h is the number of hours and w is the number of wagons sold.
We need to find the amount paid to an an employee that works 6 hours abs sells 3 wagons.
Put h = 6 and w = 3 in above equation.
12h+30w = 12(6)+30(3)
= 72+90
= 162
So, the required amount is equal to $162.

the difference between two numbers is 14. if 1/3 of the larger number is subtracted from the smaller number ,the result equals 1/10 of their sum. find both numbers
Step by step please
Answer:
Step-by-step explanation:
x-y=14
x-1/3y=1/10
-y=14-x
y=-14+x
take out the factors
x-10/30y=3/30
30x-10y=3
substitute
30x-10(-14+x)=3
30x+140-10x=3-140
20x/20=-137/20
x=-6.85
y=-14+(-6.85)
y=-20.85
The two numbers are 143/20 and 423/20.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
Given that, the difference between two numbers is 14.
Let the smaller number be x and the larger number be y.
Here, y-x=14 ------------(i)
If 1/3 of the larger number is subtracted from the smaller number ,the result equals 1/10.
1/3 of larger number is 1/3 y
x-y/3 =1/10 ------------(ii)
From equation (i), substitute y=14+x in equation (ii), we get
x-(14+x)/3 =1/10
10(3x-14-x)=3
30x-140-10=3
20x-140=3
20x=143
x=143/20
Substitute x=143/20 in equation (i), we get
y-143/20=14
y=14+143/20
y=(280+143)/20
y=423/20
Therefore, the two numbers are 143/20 and 423/20.

Answer:
66 cm²
Step-by-step explanation:
From the given figure, and the question statement we have;
BD = 11 cm, AE = 7 cm, CF = 5 cm
The given quadrilateral ABCD consists of two triangles; ΔABD and ΔBCD
The area of quadrilateral ABCD = The sum of the areas of ΔABD and ΔBCD
The base length of the two triangles equals segment BD = 11 cm
The height of triangle ΔABD = 7 cm
The area of a triangle = (1/2) × Base length × Height
∴ The area of triangle ΔABD = (1/2) × 11 cm × 7 cm = 38.5 cm²
Similarly;
The area of triangle ΔBCD = (1/2) × 11 cm × 5 cm = 27.5 cm²
∴ The area of quadrilateral ABCD = 38.5 cm² + 27.5 cm² = 66 cm²
The area of the given figure (quadrilateral ABCD) = 66 cm².
