Step-by-step explanation:
For each side of each triangle, think of the side as the hypotenuse of a right triangle. Then use the Pythagorean theorem to find the length of the hypotenuse, which is the side of the triangle.
Left problem:
From point C to point A, go 2 left and 7 up.
[tex] AC = \sqrt{2^2 + 7^2} = 7.3 [/tex]
From point A to point B, go 5 right and 1 down.
[tex] AB = \sqrt{5^2 + 1^2} = 5.1 [/tex]
From point B to point C, go 6 down and 3 left.
[tex] BC = \sqrt{6^2 + 3^2} = 6.7 [/tex]
Perimeter = 7.3 + 5.1 + 6.7 = 19.1
Do the same for the other triangles.
Middle problem:
From point F to point D, go 2 left and 7 up.
[tex] FD = \sqrt{2^2 + 7^2} = 7.3 [/tex]
From point D to point E, go 7 right and 2 down.
[tex] DE = \sqrt{7^2 + 2^2} = 7.3 [/tex]
From point E to point F, go 5 down and 5 left.
[tex] EF = \sqrt{5^2 + 5^2} = 7.1 [/tex]
Perimeter = 7.3 + 7.3 + 7.1 = 21.7
Right problem:
From point L to point J, go 7 left and 1 up.
[tex] LJ = \sqrt{7^2 + 1^2} = 7.1 [/tex]
From point J to point K, go 4 up and 5 right.
[tex] JK = \sqrt{4^2 + 5^2} = 6.4 [/tex]
From point K to point L, go 2 right and 5 down.
[tex] KL = \sqrt{2^2 + 5^2} = 5.4 [/tex]
Perimeter = 7.1 + 6.4 + 5.4 = 18.9

For questions 1 – 6, find the area of the circle to the nearest hundredth.
Any help appriciated!
Answers
Step-by-step explanation:
The area of a circle is given by :
A = πr²
r is the radius of the circle
(4) Diameter = 22 cm
Since, radius = diameter/2
r = 11 cm
Now, area of the circle,
[tex]A=\pi \times (11)^2\\\\A=380.13\ cm^2[/tex]
(5) Diameter = 30 cm
Since, radius = diameter/2
r = 15 cm
Now, area of the circle,
[tex]A=\pi \times (15)^2\\\\A=706.85\ cm^2[/tex]
(6) Diameter = 4cm
Since, radius = diameter/2
r = 2 cm
Now, area of the circle,
[tex]A=\pi \times (2)^2\\\\A=12.56\ cm^2[/tex]
So, the area of circles 4,5 and 6 are 380.13², 706.85² and 12.56² respectively.

The natural market sells a 12-ounce jar of peanut butter for $3.96. They also sell bulk peanut butter for $5.50 per pound. The ____ has a cheaper unit rate.
Answers
Answer:
The Jar of peanut butter
Step-by-step explanation:
The easiest way to do this is to calculate price per ounce of each unit.
We'll assign the 12 ounce jar to the variable s and the bulk to the variable b.
First create an equation to find the values of each product per ounce.
Since the 12 ounce jar(s) sells for 3.96 we can say it is 3.96 for every 12 ounces, or s = 3.96/12oz.
Simplify this equation and you get s = 0.33 per ounce.
For b we need to convert pounds to ounces.
There are 16 ounces per pound so the equation we get is:
b = 5.50/16oz
Simplified we get:
b = about 0.34/oz
The smaller jar has a rate of $0.33/oz
The bulk has a rate of $0.34/oz
This means the answer is b. The jar of peanut butter has a cheaper unit rate.
Answer:

SOLUTION:
[tex] -2.5f + 0.3f - 16 - 9 [/tex]
Add like terms together
-2.5f and 0.3f are like terms. If you add them together you'd get -2.5f + 0.3f = -2.2f
-16 and -9 are like terms. Adding toghter, you'd get -16 +(-9) = -25

if 50% is 7 what is 25%, 75%, and 100%
Answers
Answer:
100% = 14
75% = 10.5
25% = 3.5
Answer:
100% = 1475% = 10 1/250% = 725% = 3 1/2Step-by-step explanation:
50% if a number is also 1/2 of that number. So, we multiply 7 by 2 to get 14.
Now we know that we need to solve for 25%, 75%, and 100% of 14.
100% of a number is just that number, so 100% of 14 is 14.
To solve for 75% of 14, we multiply 3/4 by 14.
3/4 x 14/1 = 42/4 = 10 1/2
The final number to solve for is 25% of 14.
1/4 x 14/1 = 14/4 = 3 1/2

f(x) = 2x^2-5x -3
g(x) = x^2 + 6x -1

While on a trip, you notice that the video screen on the airplane, in addition to showing movies and news, records your altitude (in kilometers) above the ground.
As the plane starts its descent
(at time x = 0), you record the following data: Time, x (min.) Altitude, y (km)
12 0 10 8 16 16 18 4 110 12
If you were to graph these points on a graph, you would notice that the line that forms represents a linear function. What is the practical meaning of slope in this situation?
a. For every minute that passes, the airplane descends 1 kilometer.
b. For every minute that passes, the airplane ascends 1 kilometer.
c. For every 2 minutes that passes, the airplane descents 1 kilometer.
d. For every minute that passes, the airplane ascends 2 kilometers. C.
Answers
Answer:

Step-by-step explanation:
edg 2020
For every minute that passes, the airplane descends 1 kilometer. then option a is correct.
How to find the rate of change of a linear equation?Suppose that the considered linear equation is of the form
y=mx+c
Then, when we change x by 1 unit, then:
The rate of change is the slope. The formula for slope is
m = y2 - y1 / x2 - x1
Using the first two points, (0, 12) and (2, 10), we have
m = (10-12)/(2-0)
m = -2/2
m = -1
This means the plane descends 1 km per minute which means in 3 minutes' time, the plane descends 3 km.
Therefore, option a. For every minute that passes, the airplane descends 1 kilometer.
