Answer 1

Answer:

C

Step-by-step explanation:

Since Δ ABC is isosceles , then AB = AC and the base angles are congruent.

∠ ACB = [tex]\frac{180-50}{2}[/tex] = [tex]\frac{130}{2}[/tex] = 65°

∠ ACB and ∠ BCE are adjacent angles and are supplementary, thus

∠ BCE = 180° - 65° = 115° → C

Answer:

1. b = 47

2. c = 18

Step-by-step explanation:

From the question given above, we can see that the two shapes are right angle triangle.

Thus, if ΔUVW ≅ ΔFED, then

1. VW = ED

2. UW = FD

3. UV = EF

1. Determination of the value of b.

UW = 47

FD = b

UW = FD

47 = b

Therefore,

b = 47

2. Determination of the value of c.

VW = c

ED = 18

VW = ED

c = 18

If yes, provide the correct Triangle Congruence Postulate or Theorem and a
congruence statement,
If no, justify your answer.

Answers

Step-by-step explanation:

The triangles are congruent due to Hypotenuse-Leg congruence. (HL congruence)

Each of the triangles have a right-angle, a congruent hypotenuse and a congruent side of the triangle.

Therefore Triangles ABC and PRQ are congruent.

Answer:

Yes

Step-by-step explanation:

Given

Right triangles with congruent hypotenuse and one leg.

This is sufficient for HL (Hypotenuse, Leg) congruence theorem

8=w, -8=w  (±8=w)

Step-by-step explanation:

192=[tex]3w^{2}[/tex]

First, divide by 3

64=w²

now take the square roots of 64 and w² ( we're thinking about which numbers/variables will be multiplied to get 64 and w². They are 8 and w. But wait! -8 can also work, since when you square it a negative number, it will turn positive. )

8=w, -8=w

You can also write it as ±8=w

Hope this helps!

Kendra bought 163 donuts for $60. Her profit was $55 once she had sold 100 donuts. Which equation below
represents Kendra's profit P(n), as a function of the number sold, n ?

Answers

Answer:

Concept: Mathematical Modeling

163 donuts for 60 She mad 55 in profit: 55/163= .33 per donut P(n)= 163(n)Note: You didn't provide the options

The equation which represents Kendra's profit P(n) will be  P(n) = 0.55n.

What is a function?

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

Given,

Profit was $55 by selling 100 donuts

Profit per donuts = 55/100 = $0.55

Let's say she sold n number of donuts

Then.

Profit P(n) = 0.55n.

Hence "Kendra's profit P(n) will be  P(n) = 0.55n".

What is an equation of the line that passes through the points (-3,-1) and
(6,2)? Put your answer in fully reduced form.

Answers

Answer:

y=1/3x

When x of the line is -3, y of the line must be -1.When x of the line is 6, y of the line must be 2. y=1/3x+b. b is what we want, the 1/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specifically passes through the two points (-3,-1) and (6,2).(-3,-1). y=mx+b or -1=1/3 × -3+b, or solving for b: b=-1-(1/3)(-3). b=0.b came out to be zero, so there is no "+b" term.

Which point is in the solution set of the given system of inequalities?

Answers

Answer:

(1/5, 9/5)

Step-by-step explanation:

Given the set of inequities

x+y>2..... 1

4x-y≥-1 .... 2

We are to get the solution point (x,y)

Solving simultaneously

From 1:

x>2-y

Substitute into 2

4(2-y)-y≥-1

4(2)-4y-y≥-1

8-5y≥-1

-5u ≥-1-8

-5y ≥-9

y≤9/5

Since x>2-y

x>2 - 9/5

x>1/5

Hence the required point is (x,y) = (1/5, 9/5)

Brad buys a jacket that is on sale for 30% off the original price.The expression p - 0.3p can be used to find the sale price of the jacket, where p is the original price of the jacket. If the original price of the jacket is $80, what is the sale price?

Answers

Answer:

$56

Step-by-step explanation:

The jacket is on sales for 30% off the original price = (0.3)

The original price (P) = $80

However, the expression "p - 0.3p" is to be used to find the sales price

The sale price = p - 0.3p

The sale price = $80 - 0.3($80)

The sale price = $80 - $24

The sale price = $56
