In a tutoring session, 2/3 of an hour was spent reviewing math problems. Adelina attended 3/4 of the tutoring session. How much

fgiga [73]

Answer:

Time spend by Adelina at the tutoring session is 30 minutes.

Step-by-step explanation:

Given : In a tutoring session, $\frac{2}{3}$ of an hour was spent reviewing math problems and Adelina attended $\frac{3}{4}$ of the tutoring session.

We have to find the time Adelina spend at the tutoring session.

We know, 1 hour = 60 minutes.

Total time taken in tutoring session = $\frac{2}{3}\times 60=40$ minutes.

also, Adelina attended $\frac{3}{4}$ of the tutoring session that is $\frac{3}{4}$ of 40 minutes.

that is $\frac{3}{4}\times 40=30$ minutes.

Thus, time spend by Adelina at the tutoring session is 30 minutes.

The answers to this question make no sense please help

N76 [4]

Answer:

Step-by-step explanation:

each die has numbers 1-6 thus there are 36 (6*6) possible outcomes

a) 18 of the 36 are even = 1/2 = .5 = 50%

b) (1,2) and (2,1) are the only 3's 2/36 = 1/18 = .055

c) there are 10 combos that are LESS THAN 6 (2,3,4,5)

10/36 = .277 = 27.7%

what is the general form of the equation of a circle with its Center at -2 1 and passing through -4 one

blondinia [14]

Answer:

$\large\boxed{x^2+y^2+4x-2y+1=0}$

Step-by-step explanation:

The standard form of an equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - center

r - radius

The general form of an equation of a circle:

$x^2+y^2+Dx+Ey+F=0$

We have the center (-2, 1). Substitute to the equation in the standard form:

$(x-(-2))^2+(y-1)^2=r^2\\\\(x+2)^2+(y-1)^2=r^2$

Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:

$(-4+2)^2+(1-1)^2=r^2\\\\r^2=(-2)^2+0^2\\\\r^2=4$

Therefore we have the equation:

$(x+2)^2+(y-1)^2=4$

Convert to the general form.

Use $(a\pm b)^2=a^2\pm 2ab+b^2$

$(x+2)^2+(y-1)^2=4\\\\x^2+2(x)(2)+2^2+y^2-2(y)(1)+1^2=4\\\\x^2+4x+4+y^2-2y+1=4\qquad\text{subtract 4 from both sides}\\\\x^2+y^2+4x-2y+1=0$
