Answer:

30 dollars left

Step-by-step explanation:

If Lily works for 10 dollars per hour and works 5 hours which adds up to 50 dollars then she buys a sweater for 20 so 50 minus 20 is 30 dollars, so Lily has 30 dollars left over.

Boston, Mass. and Columbus,Ohio are about 800 miles apart. Find the angle (in radians and in degrees) made by two rays from the
nikklg [1K]

Answer:

Angle, θ = 0.20207 Radian or 11.58°

Step-by-step explanation:

Distance between Boston, Mass and Columbus, Ohio= 800 miles

We known that the radius of the earth= 3959 miles

We known that,

⇒Arc length = theta × radius of earth

⇒(800) miles = θ × (3959) miles

⇒\dfrac{800}{3959}=\theta

Therefore, θ = 0.20207 Radian

Now, converting this value in terms of degrees,

0.20207\times \dfrac{180}{\pi}\\\\=0.20207\times \dfrac{180}{3.14}\\\\=11.58^\circ

V125BC [204]
Hello!

To solve this, find the equal to each equation.

16 / 4 + 12. ====> 4 + 12.

4 + 12 ====> 16.

4 + 24 / 2. ====> 4 + 12.

4 + 12 ====>.

16 = 16.

Hope this helps! ☺♥

what equation in slope intercept form for the line that passes through point (8,-3) and has a y intercept of -2
JulijaS [17]

Answer:

y=-8x-2

Step-by-step explanation:

The formula for slope is y2-y1/x2-x1. Take coordinate (0,-2), which is the y-intercept. We'll call that (y2,x2). Coordinate (8,-3) is (y1,x1). Put that into the formula you get, 0-8/-2-(-3). You get -8/1 which is negative 8. We now have the slope. Slope intercept form equation is y=mx+b. M is slope, so we put our slope in the equation and get, y=-8x+b. B is the y-intercept which is given. So we know that the equation to this line in slope-intercept form is y=-8x-2.

A rectangular aquarium has length (x+ 10), width (x + 4), and height (t + 6). Determine a simplified function that represents th
Helga [31]

Answer:

V = x³ + 20x² + 124x + 240

Step-by-step explanation:

Volume of a rectangular prism is width times length times height.

V = wlh

Given w = x+4, l = x+10, and h = x + 6:

V = (x + 4)(x + 10)(x + 6)

V = (x + 4)(x² + 16x + 60)

V = x²(x + 4) + 16x(x + 4) + 60(x + 4)

V = x³ + 4x² + 16x² + 64x + 60x + 240

V = x³ + 20x² + 124x + 240
