Answer:

<h2>$36.00</h2>

Step-by-step explanation:

$12.00 - the total cost of 4 of equally priced gloves

$12.00 : 4 = $3.00 - the cost of 1 glove

The cost per glove is increased by $1.00. Therefore new cost of 1 glove is

$3.00 + $1.00 = $4.00

The total cost of 9 of gloves at the new price:

9 × $4.00 = $36.00

Ricardo spends 8/9 hr. reading the paper. He spends 1/4 of the time reading world news and splits the remaining time equally bet
lapo4ka [179]
Total time spent reading is = 8/9 hour

He spends 1/4 of the time reading world news. That is =  1/4 * 8/9 =  2/9 hour

Splits the remaining time equally.  Remaining time =  8/9 - 2/9 =  6/9

Splitting it equally =  6/9  divided by 2 =  6/9  * 1/2 =  3/9  = 1/3

Time spent reading comic is = 1/3 hour

I hope this helps.

Find the standard form of the equation of the circle with endpoints of a diameter at the points (3,8) and (-7,2)
poizon [28]

(x+2)^{2}+(y-5)^{2}= 34

The equation of a circle in standard form is

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

where (a , b) are the coordinates of the centre and r is the radius

The centre is at the midpoint of the endpoints and the radius is the distance from the centre to either of the 2 endpoints

Using the midpoint formula

midpoint = [\frac{1}{2}(xx_{1}+x_{2}, \frac{1}{2}(y_{1}+y_{2}

where (x_{1},y_{1}=(3,8) and (x_{2},y_{2}=(-7,2)

centre = (\frac{1}{2}(3-7),\frac{1}{2}(8+2)) = (-2,5)

Calculate r using the distance formula

r = √(x_{2}-x_{1})²+(y_{2}-y_{1})²)

= √((3+2)²+(8-5)²) = √(25+9) = √34 ⇒ r² =(√34)² = 34

equation of circle is : (x+2)²+(y-5)² = 34
