Answer:

m<DEF = 8y - 6

Step-by-step explanation:

Given that: DEG = [tex](3y +4)^{o}[/tex], and FEG = [tex](5y-10)^{o}[/tex].

The given triangle is an isosceles triangle with sides DE ≅ DF.

But,

m<DEF = DEG + FEG

            =  [tex](3y +4)^{o}[/tex] + [tex](5y-10)^{o}[/tex]

            = 3y + 4 + 5y - 10

            = 8y - 6

m<DEF = 8y - 6

Therefore, the measure of < DEF is 8y - 6.

Answer:20

Step-by-step explanation:

Answer:

Service A is represented by Line m

Service B is represented by Line ℓ

For Service B, is the additional charge per mile is less than 30 cents per mile

He can buy 5 of the $3 nut and 1 of the $5 nuts.

5x3=15

5x1=5

15+5=20 and that’s less than 24.

So Jim can use $20 to buy the $3 one 5 times and the $5 one 1 time.

Answer:

The length of the missing side is:  x = 15

Thus, option A) is the correct option.

Step-by-step explanation:

Let 'x' be the missing sides.

From the given triangle, it is clear that the segment cuts the sides into proportional ratios such 9 : 12 and x : 20 respectively.

Therefore,

9 : 12 = x : 20

9/12 = x/20

cross multiplication

12 × x = 20 × 9

12x = 180

divide both sides by 12

12x/12 = 180/12

x = 15

Therefore, the length of the missing side is:  x = 15

Thus, option A) is the correct option.

Answer:

x = 20°

Step-by-step explanation:

An equilateral triangle has three equal angles of 60° each.

Since ∆BCD is an equilateral triangle, it follows that:

<CBD = <BCD = <CDB = 60°

m<ACD = 40° + <BCD

m<ACD = 40° + 60° (substitution)

m<ACD = 100°

x + m<ACD + CDB = 180° (sum of triangle)

x + 100° + 60° = 180° (substitution)

x + 160 = 180

Subtract 160 from each side

x = 180 - 160

x = 20°

Answer:

Step-by-step explanation:

A function is a mathematical device that converts one value to another in a known way. We can think of it as a machine. You feed the machine an input, it does some calculations on it, and then gives you back another value - the result of the calculations. The set of allowable inputs to a given function is called the domain of the function

Answer:

Heres some sentences.

Step-by-step explanation:

A function works like a machine. Numbers are put into the machine one at a time, and then the rule performs the operation(s) on each input to determine each output.

Answer: In algebra, a quadratic equation (from the Latin quadratus for " square ") is any equation having the form where x represents an unknown, and a, b, and c represent known numbers, with a ≠ 0. If a = 0, then the equation is linear, not quadratic, as there is no term.

Step-by-step explanation:

Answer:

 B                                                  

Step-by-step explanation:

Hey there !!!

the question is incomplete the full question is Which of the following statements is TRUE/CORRECT about Quadratic Equations? A quadratic equation is _____

with options

A) an expression with a single variable and degree 2

B) an equation with a single variable and degree 2

c) an equation with only degree to 2

D) an equation with single variable only

and the correct answer is B

because Quadratic Equation states that An equation with one variable and degree 2 is a Quadratic Equation. Only option b satisfies the two basic conditions of a quadratic equation i.e. one/single  variable and degree 2. Hence b is the correct answer.

Answer:

An equilateral triangle has all its 3 angles the same.

Hope this helped. :)  

Equilateral triangle:

An equilateral triangle is a triangle having three equal sides, or what is sometimes referred to as a "regular" triangle. Because all three sides of an isosceles triangle are equal, an equilateral triangle is a particular case of an isosceles triangle.

Additionally, an equilateral triangle has three equal angles of 60 degrees.

Equilateral Triangle Perimeter:

In geometry, any polygon's perimeter is equal to the sum of its sides. The perimeter of an equilateral triangle is equal to the sum of its three sides.

In the event that ABC is an equilateral triangle, then its perimeter is;

Perimeter = AB + BC + AC

P = a + a + a

P = 3a    [where "a" is the triangle's side length.]

Answer:

ok so you first point is the y intercept =5 plot this at 5 on the y axis/vertical line from there you plot your slope =1/2 you go up 1 and over 2

Answer: you calculate where the points are and place them in the coordinated spots

Step-by-step explanation:

When looking at coordinates, the first number is on the x axis(horizontal/ side to side line) and the second in on the y axis(vertical/ up and down line) then counting the lines of the point over to the given x axis number, then up the given y axis number

Answer:

[tex]x = 4[/tex] -- Marcus

[tex]y = 11[/tex] -- Raquel

Step-by-step explanation:

Given

[tex]x =Marcus[/tex]

[tex]y = Raquel[/tex]

[tex]x + y = 15[/tex] -- Both

[tex]y = 2x + 3[/tex] -- Raquel

Required

Determine x and y

Substitute 2x + 3 for y in [tex]x + y = 15[/tex]

[tex]x + 2x + 3 = 15[/tex]

[tex]3x + 3 = 15[/tex]

Collect Like Terms

[tex]3x = 15-3[/tex]

[tex]3x = 12[/tex]

Divide both sides by 3

[tex]x = 4[/tex]

Substitute 4 for x in

[tex]y = 2x + 3[/tex]

[tex]y = 2 * 4 + 3[/tex]

[tex]y = 8 + 3[/tex]

[tex]y = 11[/tex]

Step-by-step explanation:

Answer:

Volume is 718 cm^3

Step-by-step explanation:

We need to get the radius of cylinder A

From the base area,

we have that;

A = pi * r^2

18 = 3.142 * r^2

r^2 = 18/3.142

r^2 = 5.73

r= √5.73

r = 2.39

If two shapes are similar, we have the ratio of their corresponding sides equal;

Thus;

2.39/5 = x/10

x = (10 * 2.39)/5

x = 4.78 cm

To get the volume, we use the formula

V = pi * r^2 * h

V = 3.142 * 4.78^2 * 10

V = 717.8 cm^3

This is approximately 718 cm^3
