Don and Marie like to go to a good restaurant. Dinners are $16 to $19 dollars with soup or salad. A beverage is $1.50. Dessert i

s $3.75. If one dinner is $16, the other is $19 and each diner has a beverage and dessert, what will the cost be if a 6% tax is charged and a 15% tip on the pre-tax amount is left?

Hi there!

The correct answer is calculated like so:

16 + 19 + 3 + 3.75 + 3.75 = 45.5

45.5 * 0.06 = 2.73

45.5 * 0.15 = 6.83

45.5 + 2.73 + 6.83 = $55.06

Answer: $55.055

Step-by-step explanation:

The cost of one dinner = $16+$1.50+$3.75=21.25

The cost of the other dinner = $19+$1.50+$3.75=24.25

The total cost of both the dinners = 21.25+24.25=\$\ 45.5

The 15% tax on the cost of dinners = 0.15\times45.5=\$\ 6.825

The 6% tax on the dinners =0.06\times45.5=\$2.73

The total cost of the dinners =\$\ 45.5+\$\ 6.825+\$\ 2.73=\$55.055

The cost of dinners if a 6% tax is charged and a 15% tip on the pre-tax amount is left =$55.055

CAn you help me with ratios? Mrs. Sturkie mixed 3 quarts of blue paint and 2 quarts of red paint to make purple paint to her cla
fredd [130]
So as we already know the ratio is 3 quarts blue paint to 2 quarts red paint, also written as 3:2. if she only has 1 quart blue paint she will need half of a quart of red paint because the ratio has to remain the same amount. if you multiply one side then you must multiply the other. same goes with division. If she only has 1 quart of red paint then that shows she divided the 2 red by 2. There fore you would have to divided the 3 by 2 in order to get 1.5 which would then make the ratio 1.5:1

I have no idea how to do this, it is due in two days. Hopefully someone sees this before then.

Hello,

m\ \widehat{ABC}=x\\m\ \widehat{BAC}=2*x\\\\So:\\ x+2x=90^o\\x=30^o\\

cos(30^o)=\dfrac{\sqrt{3} }{2} \\

In the triangle ABC,

cos(30^o)=\frac{BC}{BA} \\\\BA=\dfrac{cos(30^o)}{BC} \\\\BA=\frac{\dfrac{\sqrt{3} }{2} }{24} =16*\sqrt{3} \\\\

sin(30^o)=\dfrac{1 }{2} =\dfrac{AC}{AB} \\\\AC=\dfrac{1}{2} *16\sqrt{3} =8\sqrt{3}

In the triangle ACB,

cos(30^o)=\dfrac{AC}{AL} \\\\AL=\dfrac{8\sqrt{3} *2}{\sqrt{3} } =16\\

Given: cos θ=-4/5, sin x = -12/13, θ is in the third quadrant, 
USPshnik [31]

By definition of tangent,

tan(2<em>θ</em>) = sin(2<em>θ</em>) / cos(2<em>θ</em>)

Recall the double angle identities:

sin(2<em>θ</em>) = 2 sin(<em>θ</em>) cos(<em>θ</em>)

cos(2<em>θ</em>) = cos²(<em>θ</em>) - sin²(<em>θ</em>) = 2 cos²(<em>θ</em>) - 1

where the latter equality follows from the Pythagorean identity, cos²(<em>θ</em>) + sin²(<em>θ</em>) = 1. From this identity we can solve for the unknown value of sin(<em>θ</em>):

sin(<em>θ</em>) = ± √(1 - cos²(<em>θ</em>))

and the sign of sin(<em>θ</em>) is determined by the quadrant in which the angle terminates.

<em />

We're given that <em>θ</em> belongs to the third quadrant, for which both sin(<em>θ</em>) and cos(<em>θ</em>) are negative. So if cos(<em>θ</em>) = -4/5, we get

sin(<em>θ</em>) = - √(1 - (-4/5)²) = -3/5

Then

tan(2<em>θ</em>) = sin(2<em>θ</em>) / cos(2<em>θ</em>)

tan(2<em>θ</em>) = (2 sin(<em>θ</em>) cos(<em>θ</em>)) / (2 cos²(<em>θ</em>) - 1)

tan(2<em>θ</em>) = (2 (-3/5) (-4/5)) / (2 (-4/5)² - 1)

tan(2<em>θ</em>) = 24/7

What value will make the equation true -21-?=1.5
AfilCa [17]

Answer: ? = -22.5

Step-by-step explanation:

Using a negative number to replace the ? turns the minus into a plus sign.

-21 - (-22.5) = 1.5 is the same as -21 + 22.5 = 1.5

Which equation is the same as “f of x equals the quantity one-fourth x plus nine all over ten”
Sergio [31]
F(x)=((1/4)x+9)/10 Because f of x = f(x), equals the quantity means =, one-fourth x is just (1/4)x, plus 9 is + 9, and all over ten means take everything previously said over ten.
