Answer:

x = 6.4 feet.

Step-by-step explanation:

If a triangle has side lengths a, b, and c then its perimeter (P) will be given by ( a + b + c ).

Now, in this problem, the perimeter of a triangle is given to be 27.1 feet,

And its sides are 9.8 feet, 10.9 feet, and x feet.

Therefore, 27.1 = ( 9.8 + 10.9 + x )

⇒ 27.1 = 20.7 + x

⇒ x = 6.4 feet (Answer)

Help Plss simply can u show step by step ?-4(8x-4)+3x

Vikentia [17]

Answer:

-4(8x-4)+3x = -29x+16

Step-by-step explanation:

1. Simplify -4(8x-4) by using the distribution property:

-4(8x) = -32x and -4(-4) = 16 so -4(8x-4) = -32x+16

2. Add 3x to the remaining equation:

-32x+16+3x = -29x+16

3. The answer is:

-29x+16

Question 13 (2 points)

Eddi Din [679]

Answer:

The math club has 22 students, and the art club has 34 students.

Step-by-step explanation:

Given that there are a total of 56 students between the art club and the math club, and that the art club has 12 more students than the math club, to determine how many students there are in each club, the following calculation must be performed:

X + X + 12 = 56

2X + 12 = 56

2X = 56 - 12

X = 44/2

X = 22

Thus, the math club has 22 students, and the art club has 34 students.

6. Two points in the plane, ????(19,4) and ????(19,−6), represent the endpoints of the diameter of a circle.

dusya [7]

Answer:

Radius = 5

center is (19,-1)

$(x-19)^2(y+1)^2= 25$

Step-by-step explanation:

Two points in the plane, (19,4) and (19,−6), represent the endpoints of the diameter of a circle.

Distance between the points is calculated using formula

$d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$=\sqrt{\left(19-19\right)^2+\left(-6-4\right)^2}=10$

diameter = 10

radius = diameter divide by 2

Radius = 5

midpoint is the center of the circle

$\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)$

$\left(\frac{19+19}{2},\:\frac{-6+4}{2}\right)$

(19,-1)

Equation of the circle

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

h,k is the center and r is the radius

h=19 and k=-1 , r=5

$(x-19)^2(y+1)^2= 25$

Last month you went on three hikes. one hike was2 3/4 miles long one was 1 1/2 miles long and was 3 3/4 miles long. in decimal h

creativ13 [48]

2 3/4 = 2.75

1 1/2 = 1.5

3 3.4 = 3.75

2.75 + 1.5 + 3.75 = 8

You hiked 8 miles last month in total.
