Step-by-step explanation:

180-30=150/3=50

3x + 30 = 180

     -30     -30     subtract 30 on both sides, solve for 180 - 30 which is 150.

___________

3x = 150

__    ___       divide 3 on both sides, solve for 150 ÷ 3 which is 50.

3       3

x = 50, final answer

Answer:

B 54.5°

Step-by-step explanation:

Since we have a triangle,

CAB + ABC + BCA = 180 (sum of angles in a triangle)

Since CAB = 80° and ABC = 45.5°, substituting these into the equation, we have

80° + 45.5° + BCA = 180°

simplifying, we have

125.5° + BCA = 180°

collecting like terms, we have

BCA = 180° - 125.5°

BCA = 54.5°

So, the answer is B

Step-by-step explanation:

The equation which represent the three squares which is divided into the 5 fifths is,

[tex]15 \times \dfrac{1}{5} = 3[/tex]

A fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,

[tex]\dfrac{a}{b}[/tex]

Here (a) is the numerator and (b) is the denominator.

A multiple of a fraction is the number which is n times of the original function.

The model represents,

[tex]3 \div 1/5[/tex]

Here, the total number of square are given is 3. These three square are then divided into the one fifth.

Thus, we get total 3 times of 5 one fifth which is equal to the entire 3 squares

.

Thus, the equation can be written for this condition as,

[tex]15 \times \dfrac{1}{5} = 3[/tex]

Hence, the equation which represent the three squares which is divided into the 5 fifths is,

[tex]15 \times \dfrac{1}{5} = 3[/tex]

Option B is the correct option.

Answer:

a.the length of midsegment of an equilateral triangle with side lengths of 12.5 cm.=12.5/2=6.25cm

b.

sinceUT is the perpendicular bisector of line segment AB, where T is on AB, find the length of AT given AT = 3x + 6 and TB = 42 - x.

than AT=BT

3x+6=42-x

3x+x=42-6

x=36/4=9

AT=3×9+6=27+6=33

c.

since angle EFG has angle bisector FH, where EF = GF, find the value of y if EH = 5y + 10 and HG = 28 - y.

EH=GH

5y+10=28-y

6y=28-10

y=18/6=3

a. The length of the midsegment of an equilateral triangle is 6.25 cm

b. The length of AT is 33 units.

c. The value of y is 3.

"It is a triangle whose all sides are equal in length and all angles measure 60° "

"It is a line that intersects another line perpendicularly and divides it into wo equal parts."

"It is a line that splits an angle into two equal angle."

"It is a triangle that has two sides of equal length."

"It is the line segment connecting the midpoints of the two sides of a triangle."

"midsegment = 0.5 × base of triangle"

a.

We have been given an equilateral triangle with side lengths of 12.5 cm.

We need to find the length of the midsegment of an equilateral triangle.

Using midsegment formula,

⇒ midsegment = 0.5 × 12.5

⇒ midsegment = 6.25 cm

Therefore, the length of the midsegment of an equilateral triangle is 6.25 cm

b.

UT is the perpendicular bisector of line segment AB, where T is on AB

We know that the perpendicular bisector  divides the line segment into two equal parts.

⇒ AT = TB

⇒ 3x + 6 = 42 - x

⇒ 3x + x = 42 - 6

⇒ 4x = 36

⇒ x = 9

So, the length of AT would be,

⇒ AT = 3x + 6

⇒ AT = 3(9) + 6

⇒ AT = 33 units

Therefore, the length of AT is 33 units.

c.

An angle EFG has angle bisector FH, where EF = GF

From given data, we can say that for it must an isosceles triangle EFG with EF = GF and base is EG.

An angle EFG has angle bisector FH and point H is on the side EG.

We know that the angle bisector of isosceles triangle is also the perpendicular bisector of the base of an isosceles triangle.

⇒ EH = HG

⇒ 5y + 10 = 28 - y

⇒ 5y + y  = 28 - 10

⇒ 6y = 18

⇒ y = 3

Therefore, the value of y is 3.

Answer:

about 7.3 units

Step-by-step explanation:

the short lengths are 2 and 7, so like i explained earlier, 2^2 + 7^7 = x^2

we can simplify this to 53 = x^2, the so x = √53, which is about 7.3.

Answer: Value of n is -6

Step-by-step explanation:

If the function f(x) is translated k units up, then its image is g(x) = f(x) + k

If the function f(x) is translated k units down, then its image is g(x) = f(x) - k

The vertex form of the quadratic function is f(x) = a(x - h)² + k, where a is the coefficient of x² and (h, k) is the vertex

The value of n is 1 when the expression k(x) = x² and p(x) = k(x) + n.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We can start by substituting the function k(x) into the expression for p(x):

p(x) = k(x) + n

p(x) = x^2 + n

We don't have enough information to determine the value of n, but we can set up an equation using some other given information. If we know that p(2) = 5, we can substitute x = 2 and solve for n:

p(2) = 2² + n = 4 + n = 5

n = 5 - 4

n = 1

Therefore,

The value of n is 1 when the expression k(x) = x² and p(x) = k(x) + n.

Answer:

The water droplet will hit the ground 1.58 seconds after it started falling.

Step-by-step explanation:

The function:

y = -16*t^2 + 40

represents the height of a water droplet t seconds after falling from an icicle.

We want to find the value of t such that the water droplet hits the ground, and this will happen when y = 0.

Then we only need to solve the equation:

0 = y =  -16*t^2 + 40

0 =  -16*t^2 + 40

16*t^2 = 40

t^2 = 40/16

t = √(40/16) = 1.58

The water droplet will hit the ground 1.58 seconds after it started falling.
