What is the area of the trapezoid?

Mathematics
1 answer:
Natali [406]3 years ago
8 0

A trapezoid is a quadrilateral with one pair of parallel sides. The formula for the area of a trapezoid is ↓

Area = \frac{1}{2} (base 1 + base 2) h

The bases of the trapezoid are the parallel sides.

In the trapezoid shown, the bases are 22.2 cm and 8.52 cm and the height of the trapezoid is 9.86 cm. Now, we can plug these numbers into our formula.

\frac{1}{2} (22.2 cm + 8.52 cm) (9.86 cm)

Next, the order of operations tells us that we need to simplify inside the parentheses first. 22.2 + 8.52 = 30.72 cm

\frac{1}{2} (30.72 cm) (9.86 cm)

\frac{1}{2} × 30.72 = 15.36

(15.36 cm) (9.86 cm) = 151.4496 cm²

25% discount for AED 4000
Lostsunrise [7]

Answer:

The 25% discount on AED 4000 will be: 1000 AED

Step-by-step explanation:

Given

  • The amount = 4000
  • Discount = 25%

In order to determine a 25% discount on the amount AED 4000, all we need means is to multiply 25/100 or (0.25) by 4000.

i.e

Discount amount = 25% of 4000

                             = 25/100 × 4000

                             = 0.25 × 4000

                             = 1000 AED

Thus, the 25% discount on AED 4000 will be: 1000 AED

What is the y-intercept of the graph of the function f(x) = x^2 + 3x + 5?
Semenov [28]

Answer:

(0,5)

Step-by-step explanation:

To find the y-intercept, substitute in 0 for x and solve for y.

y=x^2 + 3x + 5

y=(0)^2 + 3(0) +5

y=0+0+5

y=5

Since there is no x coordinate for a y-intercept, the answer is (0,5)

Which set of ordered pairs represents a function? {(0, 1), (1, 3), (1, 5), (2, 8)} {(0, 0), (1, 2), (2, 6), (2, 8)} {(0, 0), (0,
11111nata11111 [884]

Answer: {(0, 2), (1, 4), (2, 6), (3, 6)}

Step-by-step explanation:

For a relation to be considered a function, each x-value needs to have one corresponding y-value--it cannot have more than 1.

Since all the other sets of ordered pairs feature points with two x-values with different y-values, the set above is the only function of the provided options.
