Answer:

m<C = 101°

m<E = 46°

Step-by-step explanation:

*This was the only problem I could figure out so I'm sorry*

C equals 101° b/c 1/2 a circle angle equals 180° which is the line. Angle F and Angle C are corresponding interior angles (same side angles) so if both of them together should equal 180. 180 - 79 (<F) = 101 (<C).

You do the same thing to find Angle E b/c it's corresponding interior angles to Angle D.

I hope you understand this explanation

Answer:

C

Step-by-step explanation:

Recall the equation for a circle:

$(x-h)^2+(y-k)^2=r^2$ , where the center is (h,k) and the radius is r.

The given equation is:

$(x+5)^2+(y+7)^2=21^2$

Another way to write this is:

$(x-(-5))^2+(y-(-7))^2=21^2$

Thus, we can see that h=-5 and k=-7.

The center is at (-5, -7).

After a game, Coach Jones wants to serve punch to the players on her soccer team. She will mix 2 quarts of ginger ale and 1 gall

Zinaida [17]

The answer would be 24 8-ounce cups.

First you would find how many quarts over all she has which is 6, then multiply that by 32(which is the amount of ounces are in a quart), then you would get 192 which you divide by 8 to find the total amount of cups you would have which is 24.

The number of mosquitoes M(x), in millions, in a certain area depends on the June rainfall x, in inches: M(x) = 13 x - x2. What

My name is Ann [436]

Answer:

The number of mosquitoes is maximum for 6.5 inches rainfall.

Step-by-step explanation:

The given function is

$M(x)=13x-x^2$ .... (1)

where, M(x) is number of mosquitoes in millions and x the June rainfall in inches.

We need to find the rainfall that produces the maximum number of mosquitoes.

Differential the above function with respect to x.

$M'(x)=13-2x$ .... (2)

Equate first derivative equal to 0.

$13-2x=0$

$2x=13$

$x=\frac{13}{2}=6.5$

Differential function (2) with respect to x.

$M''(x)=-2$

Double derivative is negative. So, the value of function is maximum at x=6.5.

Therefore, the number of mosquitoes is maximum for 6.5 inches rainfall.

A Girl Scout camp served half of their granola with breakfast. After dinner, they put the remaining 6{,}250 \text{ g}6,250 g6, c

Iteru [2.4K]

Answer:

12.5 kilograms

Step-by-step explanation:

Given:

Half of the granola served with breakfast.

Let the amount of Granola present initially = $x$ kg

Half of it ( $\frac{x}{2}$ ) served with breakfast, so remaining granola :

$x-\dfrac{x}{2} = \dfrac{x}{2}$

After dinner, the remaining granola 6,250 gm granola was served with yogurt dessert.

First of all, let us convert it to kilogram because the answer is required in Kilograms.

We know that:

1000 gms = 1 kilograms

1 gms = 0.001 kilograms

6250 gms = 6250 $\times$ 0.001 = 6.250 kilograms

Now, as per given question statement:

$\dfrac{x}{2} = 6.250\ kg\\\Rightarrow x = 2 \times 6.250\\\Rightarrow \bold{x = 12.5\ kg}$

So, the answer is:

Girl scout camp started with 12.5 Kilograms of granola.

A pizza has a diameter of 12 inches. Each piece has a central angle of radians. What is

Firlakuza [10]

Answer:

The area of one slice of pizza is 18 in²

Step-by-step explanation:

First we have to know that the 360 ° representing the circle expressed in radians are expressed as 2π

Now we must calculate the area of the circle

a = π * r²

a = π * (12in)²

a = 144π in²

Now that we have the area of the circumference we multiply it by (π/4) / (2π)

144π in² * (π/4) / (2π) =

144 in² * 1/8 =

18 in²

The area of one slice of pizza is 18 in²
