Answer:

The area of the pizza with a diameter of 18 inches is 254.34 inches.

Step-by-step explanation:

The formula to find the area of a cirlce is A = pi x r^2 or pi times radius squared.

Second, we need to find our radius. To find the radius we need to divide the diameter by 2 to get the radius. In this case; 18 divided by 2 is 9.

Then, we need to plug the radius in the formula:

A = 3.14 x 9^2

9 squared or 9 times 9 equals 81

Next, multiply 81 by 3.14 and you get 254.34

Lastly, add the units of measurement, which would be inches.

Answer:

m∠DBF = 92°

Step-by-step explanation:

The given statements tell you that points E and F are midpoints of their respective sides of the triangle. Hence EF is parallel to AB and ...

ΔABC ~ ΔEFC

That means ∠DBF ≅ ∠EFC and their measures are 92°.

Solve the following system of equations algebraically. Verify your solution either graphically or by using matrices.

LiRa [457]

3x - y = 0 . . . (1)
5x + 2y = 22 . . . (2)

From (1), y = 3x . . . (3)

Putting (3) into (2) gives:
5x + 2(3x) = 22
5x + 6x = 22
11x = 22
x = 2

From (3), y = 3(11) = 33

x = 11, y = 33.

How does the precise nature of mathematics OR the imprecise nature of language sometimes get in the way of understanding problem

Degger [83]

Answer:

This is because mathematics uses some theories that helps to change words to equations. for example, a tree of height 50m makes a shadow on the ground. an observer standing at angle of 30 degrees, calculate the distance of the man to the tree. we use the the formula, tan (30)=opp/adj

$1 \div \sqrt{3 } = 50 \div x$

$x = 50 \sqrt{3} m$

At a 3-mile cross-country race, an athlete runs 2 miles at 6 mph and 1 mile at 12 mph. What is the athlete's average speed?

Tom [10]

Answer: the average speed is 7.5 mph or at least im pretty sure

Step-by-step explanation:

This is because if you make the 2 miles at 6 mph to 1 mile at 3 mph then you get 1 mile at 3mph and 1 mile at 12 mph. now that you have the unit rates of these you can add them. 1 + 1 = 2 miles and 3 + 12 = 15 mph now divide this by two and you get 7.5 mph per mile.

I hope this helped, if it did could you give me a good rating? lol
