Answer 1

Answer:

x = 26

Step-by-step explanation:

Angles ABC and CBD are supplementary, so they add up to 180.

(2x - 10) + (5x +8) = 180

7x - 2 = 180

7x = 182

x = 182/7 = 26

Answer:

x ≈ 14.6

Step-by-step explanation:

Using the sine ratio in the right triangle

sin59° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{17}[/tex] ( multiply both sides by 17 )

17 × sin59° = x , then

Answers

Answer:

x=-6, y=0

Step-by-step explanation:

Use the 3x-9y=-18 equation and add 9y to both sides to have 3x on its own on the left side. Then, divide by 3 on both sides. Then you'll have x=-6+3y. Plus this back into the 5x+4y=-30 equation and you'll get 5(-6+3y)+4y=-30. Use the distributive property and you'll get -30+15y+4y=-30. Simplify and get -30+19y=-30, then add 30 to both sides and you'll get 19y=0. Divide by 19 on both sides and you'll get y=0. Now that we know y=0, plug that back into the 5x+4y=-30 equation, and you'll get 5x+4(0)=-30. Simplify and you'll get 5x=-30. Divide by 5 on both sides and you'll get x=-6.

Answers

Answer:

Step-by-step explanation:

i did this

The true statement is (d) m<S = m<P

How to determine the true statement?

When a figure is rotated, the side lengths and the angle measures of the figure remain unchanged.

This means that:

The figure RST is congruent to the figure OPQ.

The choice of option that supports the above highlight is

m<S = m<P

Hence, the true statement is (d) m<S = m<P

Connor will earn more interest because he is getting compound interest.

Step-by-step explanation:

I have to assume in this case that the interest is 3.5% Per year:

Simple Interest = P(r + t)

{P = Principle, r = interest rate, t = time)

Wendy = $8,300 x (3.5% x 25)

Wendy = $7,262.50 (2 d.p)

Wendy = $8,300 + $7,262.50

Wendy = $15,562.50

Compound Interest = [tex]P (1 +r )^{t}[/tex]

{P = Principle, r = interest rate, t = time)

Connor = $8,300 x [tex](1 + 0.035)^{25}[/tex]

Connor = $19,614.93

Wendy's Interest = $15,562.50 - $8,300 = $7,262.50

Connor's interest = $ 19,614.93 - $8,300 = $11,314.93

Connor earned more interest by $4,052.43

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (-4,-6). What is the vertex of the function defined as
g(x) = f(x) + 3?

Answers

Answer:

(- 4, - 3 )

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

For

g(x) = f(x) + 3

This is the graph of f(x) shifted 3 units up

Given the vertex of f(x) = (- 4, - 6 ), then

vertex of g(x) = (- 4, - 6 + 3) = (- 4, - 3 )

A circular plate has a diameter of 9 inches. What is the area of the plate? Explain the steps you follow to get to your answer

Answers

Answer:

The area of the circular plate is: " 63.59 in² " .

______________________________________________________

Note:

______________________________________________

diameter, "d" = 9 in. (given).

radius, "r" = "d/ 2 " = "(9 inches) / 2 " = 4.5 in.

______________________________________________

Area of a circle, "A" :

A = * r² ;

in which: "A = Area of circle ("plate"); in units of "square inches"; or "in² " ;

" = 3.14 " {approximation we shall use} ;

"r = radius = 4.5 in." ;

________________________________________________________

Plug in our known values to solve for the area, "A" :

A = (3.14) * (4.5 in)² ;

A = (3.14) * (4.5)² * (in²) ;

A = (3.14) * (4.5) * (4.5) * (in²) ;

A = 63.585 in² ; round to: " 63.59 in² " .
