It is the first option because if we go by the formula y=mx+b; m is the slope (which is equivalent between both lines) and then b is the y-intercept and we can see that the blue line intersects at approximately 1 and the red line intersects at approximately-3 so this makes it so that the best option is the first one

he diameter of an ice skating rink is 44 feet. In terms of π, what is the area of the rink to the nearest square yard? (9 ft2 =

crimeas [40]

Answer:

The area of the circular ring is 53.73 π sq. yards

Step-by-step explanation:

The diameter of the skating ring = 44 ft

Diameter = 2 x Radius

⇒Radius of the ring = 44 / 2 = 22 ft

Now, 1 ft = 0.333333 yards

⇒22 ft = 22 x 0.333333 yards = 7.3333 yards

Now, Area of the circular Ring = $\pi r^2\\$

or, $A = \pi (7.33)^2$

= 53.73 π sq. yards

or, the area of the circular ring is 53.73 π sq. yards

Students are given 3 minutes to complete each multiple-choice question on a test and 8 minutes for each free-response question.

SpyIntel [72]

Let

x------> the number of multiple choice question

y------> the number of free response question

we know that

$3x+8y=55$ -----> equation A

$x+y=15$

$x=15-y$ -----> equation B

Substitute equation B in equation A

$3[15-y]+8y=55$

$45-3y+8y=55$

$5y=55-45$

$5y=10$

$y=2$

Find the value of x

$x=15-y$

$x=15-2=13$

therefore

<u>the answer is</u>

the number of multiple choice question are $13$

the number of free response question are $2$

Step-by-step explanation:

10=y-5

also can be read as y-5=10 so it would also be sayin what minus 5 equals 10.

SO 10+5= 15. Y=15
