Answers

Answer:

120 Degrees

Step-by-step explanation:

Angle T and R are vertical angles meaning they are equal so combine the equations: 31x - 4 = 29x + 4, then solve using inverse operations

subtract 31x from both sides to get -4 = -2x + 4

Then subtract 4 from both sides to get -8 = -2x, now that we have isolated the variable we have to divide by -2 on both sides getting us x = 4, then plug in the four to the equation for angle R getting you 29 times 4 which equals 116 + 4 = 120

Jenna is planting four circular gardens. She is planting one garden each for tomatoes, carrots, cabbage, and strawberries. Each garden will have a fence around it to keep rabbits out. The tomato, carrot, and cabbage gardens will all be the same size. Since Jenna loves strawberries, the strawberry garden will be larger. It will use the same amount of fencing as the other three gardens combined. She used a total of about 113.04 feet of fencing material.
The area of each smaller garden is about ___
square feet.

The area of the larger garden is about ____
square feet.

The area of the larger garden is ___
times larger than the area of the smaller garden.

Answers

Answer:

254.34 square feet in the larger green

Step-by-step explanation:

Tomato + carrot + cabbage + ( 3* carrot) =113.04 ft

1x+1x+1x+3 x= 113.04

6x= 113.04

x=113.04/6 = 18.84 feet of fence = circumference

The circumference of the tomato, carrot and cabbage gardens is 18.84 feet each. The circumference of the strawberry garden will be 3 times larger of 3x 18.84 = 56.52 feet.

With the circumference we can find the diameters, and with the diameters we can find the areas.

For the 3 small gardens, d= c/[tex]\pi[/tex]

d= 18.84 / 3.14

d=6 and the radius is 3 feet

Area = [tex]\pi[/tex]^2

A= 3.14 x 3 x 3= 28.26 square feet in each of the 3 small gardens

For the larger garden

d=6x3=18 feet and the radius is 9 feet

Area = [tex]\pi[/tex]^2

A= 3.14 x 9 x 9 = 254.34 square feet in the larger garden

Triangle JML= 180( Angle sum property)

2x+ 48= KML( Exterior angle property)

In triangle JML,

76 + ∠L+ ∠KML=180°

∠KML=∠L( angles opposite to equal sides are equal)

76+2(2x+48)=180°

2(2x+48)=104°

2x=104-48=64°

tan x = 32 / 24

professor wrote the following inequalities for N number of students in his lecture. N <10, N>10, N<22, N>22. Turns out only one statement is correct. How many students were in his lecture​

Answers

Answer:

There are N students in the class.

We know that ONLY ONE of the inequalities is true:

N < 10

N > 10

N < 22

N > 22

We want only one of these four inequalities to be true.

Remember that if we have:

x > y

y is not a solution, because:

y > y is false.

Then:

If we take N = 10, then:

N < 22

Is the only true option.

While if we take N = 22

N > 10

is the only true option.

So there are two possible values of N.
