Evaluate using suitable identity:
e). 102 × 98
Step-by-step explanation:
★ Solution :-[tex]\sf \longmapsto 102 \times 98[/tex]
[tex]\sf \longmapsto (a + b)(a - b) = a^2 - b^2[/tex]
Here,
a = 100b = 2[tex]\sf \longmapsto (100 + 2)(100 - 2) = 100^2 - 2^2[/tex]
[tex]\sf \longmapsto 100^2 - 2^2[/tex]
[tex]\sf \longmapsto 10000 - 4[/tex]
[tex]\sf \longmapsto 9996[/tex]
Answer:
9996
Step-by-step explanation:
Algebraic Identity: (a-b)(a+b)=a²-b²
102×98=(100+2)(100-2)
=100²-2²
=10000-4
=9996

At a particular restaurant, each slider has 225 calories and each chicken wing has 70 calories. A combination meal with sliders and chicken wings has a total of 7 sliders and chicken wings altogether and contains 1110 calories. Write a system of equations that could be used to determine the number of sliders in the combination meal and the number of chicken wings in the combination meal.
Answer:
The appropriate equation for the above mentioned conditon would be
x+y=7
225x+70y=1110
Step-by-step explanation:
As mentioned in the question the meals contain just two delicacies (i.e. sliders and chicken wings)
Let the number of Sliders be represented by “x”
Let Number of Chicken wings be represented as “y”
As given in the question the total number of sliders and chicken wings equals 7
Hence x + y =7… Equation 1
Further, it is mentioned that each slider carries worth 225 calories of energy and chicken wing carries 70 calories of energy. Total calorie of a meal which contains sliders and wings is 1110 calories.
Thus, Total energy carried by sliders individually = total sliders* energy carried by one slider= 225x
Similarly, Total energy carried by wings individually = total chicken wings* energy carried by one wing= 70y
Thus 225x+70y=1110
∠1 and ∠2 are complementary angles. m∠1 is 5y+32 and m∠2 is 7y-14. Find m∠2 & show your work.
it was deleted last time I posted it???
[tex]\\ \sf\longmapsto 5y+32+7y-14=90[/tex]
[tex]\\ \sf\longmapsto 12y+18=90[/tex]
[tex]\\ \sf\longmapsto 12y=72[/tex]
[tex]\\ \sf\longmapsto y=6[/tex]
m<2=7(6)-14=42-14=28[/tex]The required value of m∠2 would be 30 degrees when the value of y = 6 due to the given pair of angles being complementary.
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles.
We have been given that the pair of angles as
(5y + 32)° and (7y - 14)°
∵ ∠1 and ∠2 are complementary angles
Here, the pairing of angles sums up to 90° then they are called complementary angles.
So 5y + 32 + 7y - 14 = 90°
⇒ 12y + 18 = 90
⇒ 12y = 72
⇒ y = 6
So m∠2 = 7y - 14
Substitute the value of y = 6 in the above equation, and we get
So m∠2 = 7(6) - 14 = 42 -12 = 30
Therefore, the value of m∠2 would be 30 degrees when the value of y = 6.

Step-by-step explanation:
1.
a. Isosceles right triangle
a° = 180 - (90 + 20)
a° = 180 - 110 = 70
b. Isosceles acute triangle
a° = 180 - (70+70)
a° = 180 - 140 = 40
c. The three angles inside a triangle always add up to 180°
∠A = 180 - (70 + 60)
∠A = 180 - 130
∠A = 50
so a° = 180 - 50 = 130
d. Isosceles acute triangle
∠A = 180 - (65 + 65)
∠A = 180 - 130
∠A = 50
so a° = 180 - 50 = 130
e. The angles of a rectangle add up to 360°
a° = 360 - (100 + 95 + 70)
a° = 360 - 265
a° = 95
f. The angles of a rectangle add up to 360°
2a° = 360 - (70 + 60)
2a° = 360 - 130
2a° = 230
a° = 115
2.
a. Straight angle is 180°
180 - 141 = 39
so x° = 180 - (39 + 39)
x° = 180 - 78
x° = 102
b. The three angles inside a triangle always add up to 180°
180 - (40 + 60)
180 - 100 = 80
opposite angle
x° = 180 - (80 + 35)
x° = 180 - 115 = 65
c. The angles of a rectangle add up to 360°
(x + 20)° + x° = 360 - (90 + 90)
(x + 20)° + x° = 360 - 180
(x + 20)° + x° = 180
x° = 80

Your camera determines the focal distance required for your picture to be in focus using the lens equation, 1−1=1, where the focal distance to the object from the lens(D)is related to the focal length (F)and the distance from the lens to the film (S).If an object is placed 8 cm from a lens with a focal length of 4 cm, how far from the lens is the image (film) formed?
If an object is placed 8 cm from a lens with a focal length of 4 cm, the image is 8 cm from the lens
Let the focal length be represented by f
Let the distance between the object and the lens be represented by u
Let the distance between the image and the lens be v
The focal length, f = 4 cm
The distance between the object and the lens, u = 8cm
The distance between the image and the lens, v = ?
The relationship between the focal length (f), distance between the object and the lens (u), and the distance between the image and the lens (v) is given below:
[tex]\frac{1}{u} + \frac{1}{v} = \frac{1}{f}[/tex]
Substitute f = 4, and u = 8 into the equation above:
[tex]\frac{1}{8} + \frac{1}{v} = \frac{1}{4} \\\\\frac{1}{v} = \frac{1}{4} - \frac{1}{8}\\\\\frac{1}{v} = \frac{2-1}{8}\\\\\frac{1}{v} = \frac{1}{8}\\\\v = 8[/tex]
Therefore, the image is 8 cm from the lens

Let the graph of g be a translation 4 units down followed by a reflection about the y-axis of the graph of f(x)=−3x +2
Write a rule for g.
Answer:
[tex]g(x)=f(-x)-4[/tex]
Step-by-step explanation:
Hi there!
We're given that [tex]f(x)=-3x +2[/tex].
g(x) is f(x) translated 4 units down. Subtract 4 from f(x):
[tex]g(x)=f(x)-4[/tex]
It is also reflected about the y-axis. This makes all values of x negative:

Ohio City Burgers charges $6.75 for a
burger plus $.75 for each additional
topping.
Write an equation to determine
how many toppings you can get
with a total of $10.
Answer: x = (10 - 6.75) ÷ 0.75
Step-by-step explanation:
x stands for the maximum number of toppings you can afford.
10 stands for the amount of money you have (10$).
6.75 is the amount of money spent on the Burger alone.
0.75 is the money spent on each topping with your remaining money.

Answer:
f(x) = -19
g(x) = -10
Step-by-step explanation:
just substitute.
-4(2)^2-3 = -19
-3(4)+2 = -10
Answer:
f(2) = -19
g(4) = -10
Step-by-step explanation:
f(x) = -4x² - 3 g(x)) = -3x + 2
Find f(2)
Technically, we input 2 for x in the function f(x)
Solve:
f(2) = -4(2)² - 3
f(2) = -4(4) - 3
f(2) = -16 - 3
f(2) = -19
Find g(4)
As before, we input 4 for x in the function g(x)
Solve:
g(4) = -3(4) + 2
g(4) = -12 + 2
g(4) = -10

Raisins were $700 for a measure, where as plums cost $900 a measure. David and Bruce
bought 50 measures and spent $41,000. How many measures of raisins did they
buy
Answer:
20 measures of raisins
Step-by-step explanation:
700 r + 900 p = 41000 ...... (1)
r + p = 50 ⇒ p = 50 - r ....... (2)
(2) ------> (1)
700 r + 900( 50 - r ) = 41 000
700 r - 900 r = 41000 - 45000
- 200 r = - 4000
r = 20 measures

Olivia wants to clean her mansion, so she decides to hire a cleaning company. Company Fabuloso charges an initial hiring fee of $50 plus $30 per hour. Company Clorox charges an initial fee of $70 plus $25 per hour. After how many hours will it cost the same for both companies?
Answer:
4hrs
Step-by-step explanation:
Fabuloso charges = 50 + 30x = 80
Clorux charges = 70+25x = 95
£15 difference =( 3 * 5 ) = 30-25 = 5 = 15/3
= 3hrs + 1st hour = 4hrs
Fabuloso charges = 50 + 30(4) = 80+90 = $170
Clorux charges = 70+25(4) = 95 + 75=$170
= 4hrs
