Just use the inverses: sin^-1, cos^-1, and tan^-1. For example, #13, you would type in your calculator, tan^-1 (30/33), and then you'll get 43.15 degrees.

A shop sells chocolate, vanilla and strawberry ice cream cones. In one day, 45% of the ice cream cones sold are vanilla and 17%

True [87]

Answer:

950

Step-by-step explanation:

As, 45% will be vanilla, and 17% will be strawberry

So chocolate will be = 38%

As, 45%+17%+38% = 100%

So 38% of 2,500 = chocolate cones

= 38/100 x 2,500 = 950

So the number chocolate ice cream cone sold is 950.

!!20 POINTS!! Claire filled up her car with gas before embarking on a road trip across the country. Let G represent the number o

pentagon [3]

Answer:

$G=-\frac{5}{4}t+15$

Slope = $-\frac{5}{4}$

Step-by-step explanation:

Let the equation representing the number of gallons left in the gas tank is,

G = mt + b

Where m = slope of the line

b = y-intercept of the line

Slope of the line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is,

'm' = $\frac{y_2-y_1}{x_2-x_1}$

Slope of the line passing through (8, 5) and (4, 10),

m = $\frac{10-5}{4-8}$

m = - $\frac{5}{4}$

Equation of line will be,

G = $-\frac{5}{4}t+b$

Since, point (8, 5) lies on this line,

5 = $-\frac{5}{4}(8)+b$

5 = -10 + b

b = 15

Therefore equation of the function will be,

G = $-\frac{5}{4}t+15$

Here slope of the function represents the $\frac{5}{4}$ gallons of gas is consumed to drive the car for one hour.
