Answers

Answer 1

Answer:

D

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ ADE is an exterior angle of the triangle , then

80° + ? = 100° ( subtract 80° from both sides )

? = 20° → D

A frog leaps off of a ledge and lands on the ground below. The function
f(x) = -1.6x2 + 2.3x + 3.2 represents the frog's path.
a. How high is the ledge where the frog starts?
b. How high is the frog at its highest point?
c. What is the frog's horizontal distance from the ledge when it
reaches its highest point?

Answers

Answer:

-1.6x2 + 2.3x + 3.2 = f(x) to solve this you do -1.6 x 2 = -3.2 + 2.3x = -0.9 + 3.2 = 2.3

Step-by-step explanation:

For A the height of ledge is 3.2

for b - the frogs highest point 2.30x

and c is 12.3x

Solve the simultaneous equations
5x - 4y = 19
x + 2y = 8

Answers

Answer:

x= 5 and y = 1.5

Step-by-step explanation:

5x -4y = 19

x + 2y = 8

let x = 8 - 2y...

5x - 4y = 19.......x = 8 -2y

5(8-2y) - 4y = 19

40 - 10y -4y= 19

40-14y = 19

-14y = 19-40

-14y = -21

y = 1.5

x = 8 - 2(1.5)

x = 8 - 3

x = 5

Thus, x is 5 and y is 1.5

Step-by-step explanation:

Irrational numbers are the real numbers that cannot be represented as a simple fraction. It cannot be expressed in the form of a ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.  

Irrational numbers are expressed usually in the form of R\Q, where the backward slash symbol denotes ‘set minus’. it can also be expressed as R – Q, which states the difference between a set of real numbers and a set of rational numbers.

A store sells notepads in packages of 24 and packages of 6. The organizers of a conference needs to prepare at least 200 notepads for the event. Would they have enough notepads if they bought five packages of 24 and fifteen packages of 6 ?

Answers

Answer: Yes they would have enough notepads

Step-by-step explanation:

24 * 5 = 120

15 * 6 = 90

120 + 90 = 210

The organizers will have enough notepads if they bought five packages of 24 and fifteen packages of 6.

Given that, a store sells notepads in packages of 24 and packages of 6.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Now, the number of note pads with five packages of 24

24 × 5 = 120

The number of note pads with fifteen packages of 6

15 × 6 = 90

Total number of note pads

= 120 + 90 = 210

Therefore, the organizers will have enough notepads if they bought five packages of 24 and fifteen packages of 6.

per pay period for Social Security? How much for Medicare?

Answers

Answer:

Social Security: $201.50, Medicare: $47.13

Step-by-step explanation:

divide 78,000 by 24(semimonthly) - $78000/24 = $3250(gross semimonthly basis)

multiply 3250 by .062(social security) - 3250 x .062 = $201.50

multiply 3250 by 0.0145(medicare) - 3250 x 0.0145 = $47.13
