Anna35 [415]

Answer:

(x-4)*2 + (y-2)*2 = 25

Step-by-step explanation:

(x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle.

h = 4

k = 2

r = 5

sub in all this info:

(x-4)*2 + (y-2)*2 = 25

Jessica is a custodian at Oracle Arena. She waxes 20 m2 of the floor in 3/5 of an hour. Jessica waxes the floor at a constant ra
Ghella [55]

to solve this, you need to set up an equation to solve for <em>x, </em>the number of square meters waxed in an hour:

\frac{20}{3/5}  = \frac{x }{1 }

you can use cross multiplication to solve for x:

\frac{3}{5} x = 20

3x = 100\\x = 100/3

so jessica can wax 100/3 square meters per hour. you can convert this to decimal form (which would be 33.3 repeating) or you can leave it in fraction form.

if you share the costs of a meal on the ratio of 2:3 and one person pays £52.20 how much was the whole meal?
Tju [1.3M]
<em>The ratio of shared costs of mean=2:3.
One person paid the cost </em>
£<em>52.20, so let the other person paid the cost be X.
</em>
<em>(2/3)=(52.20/X)
</em><em>X=(52.20</em>×3)/2
X=26.10×3
X=78.30
So the gross cost paid by both the person = £(78.30+52.20)
⇒£130.60

Which point is a solution to the system below 2y&lt;-12x+4 y&lt;-6x+4?
Lera25 [3.4K]

Answer: All points in the shaded region after 2y<-12x+4 is the solution.

Step-by-step explanation:

Since we have given that

2y

We need to find the point of solution to the system of inequalities:

Suppose

2y=-12x+4\\and\\y=-6x+4

We first check the consistency of the system of equation:

\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{c_1}{c_2}\\\\\frac{2}{1}=\frac{-12}{-6}=\frac{4}{4}\\\\2=2\neq 1

So, it is parallel system of equations, but we consider it as an inequality, so all the points in the shaded region is the solution.

Using zero test,

2y

0<4 it is true so, shaded part is towards the center.

Similarly,

y

0<4 again it is true it would be shaded towards the center.

So, the common part will be after 2y<-12x+4 .

Hence, all the points in the shaded region is the solution.

At noon Joyce drove to the lake at 30 miles per hour. but she made the long walk back home at 4 miles per hour. How long did she
mars1129 [50]

Answer:

60 miles

Step-by-step explanation:

let d = distance to the lake

Using:  time = distance ÷ speed

Create expressions for the time it takes for each journey:

Drive:  t_1=\dfrac{d}{30}

Walk:   t_2=\dfrac{d}{4}

If total time = 17 hours

\implies t_1+t_2=17

\implies \dfrac{d}{30}+\dfrac{d}{4}=17

\implies \dfrac{17d}{60}=17

\implies 17d=1020

\implies d=\dfrac{1020}{17}

\implies d=60

Therefore she walked 60 miles
