Answer:

1141

Step-by-step explanation:

In this equation you first multiply so 23+90-12+13x80

23 + 90 - 12 + 1040

The you can add or multiply

113 - 12 + 1040

101 + 1040

1141 is your answer

Answer:

1141

Step-by-step explanation:

The order of operations requires multiplication to be done before addition or subtraction, so we calculate 13x80 first (1040). then, we can add 23 to 90 to get 113, subtract 12 to get 101, and finally add 101 to 1040 to get 1141.

V = bdt. Solve the formula for b.

levacccp [35]

Answer:

b = $\frac{V}{dt}$

Step-by-step explanation:

Divide both sides by dt, so it cancels out.

$\frac{V}{dt} = \frac{bdt}{dt}$

$\frac{V}{dt} = b$

The curved surface area of a cylinder is 880cm2 and its volume is 770cm3.Find its diameter and height.

natima [27]

Answer:

The height of cylinder is: h = 80.07 cm

The diameter of cylinder is: d = 3.5 cm

Step-by-step explanation:

Curved surface area of cylinder = 880 cm^2

Volume of cylinder = 770 cm^3

We need to find its diameter and height.

The formula used are:

$Curved\: surface\: area=2\pi rh\\Volume=\pi r^2h$

If we divide volume by curved surface, we can find radius

$\frac{Volume}{Curved\: surface\: area}=\frac{\pi r^2h}{2\pi rh} \\\frac{770}{880}=\frac{r}{2}\\0.875= \frac{r}{2}\\=> r= 0.875\times 2\\r=1.75$

So, we get radius r = 1.75

Now, we can find height using curve surface area formula:

$Curved\: surface\: area=2\pi rh\\880=2(3.14)(1.75)h\\h=\frac{880}{10.99}\\h=80.07 \:cm$

So, the height of cylinder is: h=80.07 cm

Now finding diameter using formula: $d=2r$

Putting value of r in above formula:

$d=2r\\d=2(1.75)\\d=3.5\:cm\\$

So, the diameter of cylinder is: d = 3.5 cm

Which statement is true regarding the functions of the graph?

gregori [183]

Answer:

f(- 3) = g(- 3)

Step-by-step explanation:

f(x) and g(x) are equal at the point of intersection.

When x = - 3 , f(- 3) = - 4 and g(- 3) = - 4

Thus

f(- 3) = g(- 3)

Can someone’s please help

Fiesta28 [93]

Answer:

4.87 ft

Step-by-step explanation:

The height of the skylight =

The height of the blue △ - the height of the red △

Let b ft be the height of the blue △.

sin 60° = $\frac{b}{25}$

b = 25 sin 60°

Let r ft be the height of the red △.

tan 40° = $\frac{r}{20}$

r = 20 tan 40°

The height of the skylight

= 25 sin 60° - 20 tan 40°

= 4.87 ft (rounded to the nearest hundredth)
