Answer:

The cost of one donuts is $1.25 and the cost of one cinnamon is $1.75

Step-by-step explanation:

Let

x-----> the cost of one donuts

y ----> the cost of one cinnamon

we know that

$5x+3y=11.50$ -----> equation A

$8x+6y=20.50$ -----> equation B

Solve the system by graphing

Remember that the solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (1.25,1.75)

see the attached figure

therefore

The cost of one donuts is $1.25 and the cost of one cinnamon is $1.75

7-2(2+3x)=27what is he answer

Taya2010 [7]

<span>Simplifying 7 + -2(2 + 3x) = 27 7 + (2 * -2 + 3x * -2) = 27 7 + (-4 + -6x) = 27 Combine like terms: 7 + -4 = 3 3 + -6x = 27 Solving 3 + -6x = 27 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -3 + -6x = 27 + -3 Combine like terms: 3 + -3 = 0 0 + -6x = 27 + -3 -6x = 27 + -3 Combine like terms: 27 + -3 = 24 -6x = 24 Divide each side by '-6'. x = -4 Simplifying x = -4</span>

For the following problem, assume that all given angles are in simplest form, so that if A is in QIV you may assume that 270° &l

d1i1m1o1n [39]

Answer:

Step-by-step explanation:

Given that angle A is in IV quadrant

So A/2 would be in II quadrant.

sin A = -1/3

cos A = $\sqrt{1-sin^2 A} =\frac{2\sqrt{2} }{3}$

(cos A is positive since in IV quadrant)

Using this we can find cos A/2

$cosA = 2cos^2 \frac{A}{2} -1\\Or cos \frac{A}{2} =-\sqrt{\frac{1+cosA}{2} } =-\sqrt{\frac{3+2\sqrt{2} }{6} }$

A circular mirror has a diameter of 12 inches. And a circular frame that is 3 inches wide surrounds the mirror. What is the comb

Lapatulllka [165]

Answer:

254.5 in.^2

Step-by-step explanation:

diameter of mirror = 12 in.

radius of mirror = diameter/2 = 13 in. / 2 = 6 in.

frame width = 3 in.

radius if combined mirror and frame = 6 in. + 3 in. = 9 in.

A = (pi)(r^2)

A = 3.14159 * (9 in.)^2

A = 3.14159 * 81 in.^2

A = 254.5 in.^2
