What is the perimeter of the triangle shown on the coordinate plane, to the nearest tenth of a unit?

Akimi4 [234]

Answer:

25.6 units

Step-by-step explanation: From the figure we can infer that our triangle has vertices A = (-5, 4), B = (1, 4), and C = (3, -4).

First thing we are doing is find the lengths of AB, BC, and AC using the distance formula:

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

where

(x_1,y_1) are the coordinates of the first point

(x_2,y_2) are the coordinates of the second point

- For AB:

d=\sqrt{[1-(-5)]^{2}+(4-4)^2}

d=\sqrt{(1+5)^{2}+(0)^2}

d=\sqrt{(6)^{2}}

d=6

- For BC:

d=\sqrt{(3-1)^{2} +(-4-4)^{2}}

d=\sqrt{(2)^{2} +(-8)^{2}}

d=\sqrt{4+64}

d=\sqrt{68}

d=8.24

- For AC:

d=\sqrt{[3-(-5)]^{2} +(-4-4)^{2}}

d=\sqrt{(3+5)^{2} +(-8)^{2}}

d=\sqrt{(8)^{2} +64}

d=\sqrt{64+64}

d=\sqrt{128}

d=11.31

Next, now that we have our lengths, we can add them to find the perimeter of our triangle:

p=AB+BC+AC

p=6+8.24+11.31

p=25.55

p=25.6

We can conclude that the perimeter of the triangle shown in the figure is 25.6 units.

When someone donated 14 gallons of paint to Rosendale Elementary School, the fifth grade decided to use it to paint murals. They

Naddika [18.5K]

Answer:

Answered

Step-by-step explanation:

Total amount of paint = 14 gallons

the paint was distributed equally among 4 classes

a. therefore each class would get $\frac{14}{4}$ gallons of paint

= $3\frac{1}{2}$ gallons each

b.Three classes will use 3× paint of each class

= $3\times3\frac{1}{2}$ = 10(1/2) gallons

c. 4 student paint 30 square-foot wall the each student would paint

$\frac{30}{4}$ = 7(1/2) square-foot wall.

d. each student will paint $\frac{1}{4}$ of the wall since there are 4 students.

Find the value of a from the following data whose mean is 23 29,33, 27, a, 19, 17, 10

ollegr [7]

Answer:

a = 26

Step-by-step explanation:

29 + 33 + 27 + a + 19 + 17 + 10 / 7 = 23

135 + a / 7 = 23

135 + a = 161

a = 26
