Answer:

Step-by-step explanation:

3 consecutive numbers can be:

$x-1, x, x+1$ ; for example: 1, 2, 3 (1 is 1 less than 2, and 3 is 1 more than 2)

The sum is all of them added, so

$x-1+x+x+1=270; 3x=270; x=90$

90 is the middle number though, so the first number is 89

A ball is thrown from the top of the school. The height of the ball (in feet) written in

seropon [69]

Answer:

3 seconds

Step-by-step explanation:

When the ball hits the ground, the height will be 0. Therefore, you can substitute 0 in for the value of f(t), hence the equation will be:

0 = -16t^2 + 32t + 48

You can then factor out -16:

0 = t^2 - 2t - 3

Factor:

0 = (t-3)(t+1)
t = 3, -1

However -1 is an extraneous solution because time cannot be negative. Therefore, the answer is 3 seconds.

The ratio of angles angles A:B:C is 5:4:3 . find measure of angle A and B And C

mr Goodwill [35]

Answer:

A=75

B=60

C=45

Step-by-step explanation:

5+4+3=12

every triangle is equal to 180 so we divide

180/12=15

then we multiply each angle by 15

5*15

4*15

and 3*15

don't forget to check your work by adding the answers together to get 180

Drag and drop the symbols to enter the equation of the circle in standard form with center and radius given.

Leya [2.2K]

The standard equation of a circle with center C(a, b) and radius r is given by:

$(x-a)^2+(y-b)^2=r^2$

thus for C(a, b)=C(7, 5) and radius r=4, the equation is given by:

$(x-a)^2+(y-b)^2=r^2\\\\(x-7)^2+(y-5)^2=4^2$

Answer:

$(x-7)^2+(y-5)^2=4^2$
