By eating 1 egg, 1 cupcake, and 1 slice of pizza, a child consumes 300 mg of cholesterol. If the child eats 3 cupcakes and 4 sli

photoshop1234 [79]

Answer:

cholesterol in egg= 273 mg

cholesterol in cupcake = 18 mg

cholesterol in slice of pizza = 9 mg

Step-by-step explanation:

Given data:

1 egg , 1 cupcake , 1 slice of pizza = 300mg

3 cupcakes , 4 slices of pizza = 90mg

2 eggs , 1 cupcake = 564mg

Let egg be x , let cupcake be y and let pizza be y

x + y + z = 300 (equation 1)

0x + 3y + 4z = 90 (equation 2)

2x + y + 0z = 564 (equation 3)

Using equation 1 and equation 2

x + y + z = 300 (Multiply equation by 3)

0x + 3y + 4z = 90

3x + 3y +3z =900

0x +3y +4z = 90 (Subtracting the equations)

3x - z = 810 (equation 4)

Using equation 2 and equation 3

0x + 3y + 4z = 90

2x + y + 0z = 564 (Multiply equation by 3)

0x + 3y + 4z = 90

6x +3y + 0z = 1692 (Subtracting the equations)

-6x +4z =-1602 (equation 5)

Solving equation 4 and equation 5

3x - z = 810 therefore z =3x -810

Substituting z into equation 5

-6x +4(3x - 810) =-1602

-6x + 12x - 3240 = -1602

6x = -1602+3240

6x = 1638

x = 273

Substituting x into z = 3x - 810

z = 3(273) - 810

z = 819-810

z = 9

Using equation 1 to find y

x + y + z = 300

273 + y + 9 = 300

282 + y = 300

y = 300-282

y = 18

Assume that θ is an acute angle in a right triangle satisfying the given conditions. Evaluate the 5 remaining trigonometric func

neonofarm [45]

Answer: See step by step. Replace the x with theta

Step-by-step explanation: Since sin is less than zero, and secant is positive. This means the trig values are in Quadrant 4.

We know that secФ=17/15. We need to find sin,cos,tan,csc, and cot.

We can find tangent by using the identity

$tan^{2} (x)+ 1=sec^{2} (x)$ where x is theta.

$tan^{2} (x)+1=\frac{289}{225}$

$tan^{2} (x)+\frac{225}{225} =\frac{289}{225}$

$tan^{2}(x)=\frac{64}{225}$

tan x= $\frac{8}{15}$ , Tangent in the fourth quadrant is negative so the answer is instead

$tan x= -\frac{8}{15}$

We can find cotangent by taking the recipocial of tan so

$cot=-\frac{15}{8}$

We can find cos by taking reciprocal of sec remeber that cosine is positive in 4th quadrant so the answer is

$cos =\frac{15}{17}$

We can find sin by doing quoteint identies.

$\frac{sin x}{cos x} =tan x$

$\frac{ sin x}{15/17} =-\frac{8}{15}$

$sin x= -\frac{8}{17}$

To find csc, take reciprocal of sine.

$csc=\frac{-17}{8}$
