Mathematics
1 answer:
statuscvo [17]3 years ago
5 0

Answer:

A: x=16

B: ∠A=22

Step-by-step explanation:

A

The angles in a triangle always add up to 180. Therefore:

∠A+∠B+∠C=180

(2x-10)+(3x)+(4x+46)=180

2x+3x+4x+46-10=180

9x=180-36

x=144/9

x=16

B

∠A=2x-10

∠A=2(16)-10

∠A=32-10

∠A=22

The diameter of a circle is 20 ft. Find its area in terms of T.
Ksivusya [100]

Answer:

314.2ft^2

Step-by-step explanation:

Given data

Diameter= 20ft

Radius r= 20/2= 10ft

The expression for the area is

A= πr^2

A= 3.142*10^2

A= 3.142*100

A= 314.2ft^2

Hence the area is 314.2ft^2

A conveyor belt carries supplies from the first floor to the second floor, which is 39 feet higher.
Murljashka [212]

The supplies travelled 45ft and it took 0.6min to get to the next floor.

<h3>What is trigonometry?</h3>

Trigonometry is the branch of mathematics dealing with the relationship between the sides of a triangle and the angles.

Analysis:

The supplies distance travelled, distance of first floor from second floor and the ground form a right angled triangle.

so that sin 60 = 39/distance travelled by supplies

distance travelled by supplies = 39/sin 60 = 39/0.866 = 45 feet.

speed = distance / time

time = distance / speed = 45/70 = 0.6 min

In conclusion, the distance and time time taken for the supplies to get to the next floor is 45feet and 0.6 min respectively.

Margo freezes 8 cups of strawberries if this is 2/3 of the total strawberries that she picked how many cups of strawberries did
Goryan [66]

Answer:

12 cups.

Step-by-step explanation:

Let x be the total cups of strawberries picked by Margo.

We have been given that Margo freezes 8 cups of strawberries and this is 2/3 of the total strawberries that she picked.

We need to find x such that 2/3 of x equals 8. We can represent this information in an equation as:

\frac{2}{3}x=8

Let us multiply both sides of our equation by 3.

3*\frac{2}{3}x=3*8

2x=24

Let us divide both sides of our equation by 2.

\frac{2x}{2}=\frac{24}{2}

x=12

Therefore, Margo picked 12 cups of strawberries.
