This is a kite. We can split it into 2 equal triangles.

Length = 42.7 + 22.5 = 65.2cm
Height = 16.3 cm

Area of triangle = 1/2 x base x height

2 Area of triangles = 2( 1/2 x 65.2 x 16.3) =  1063 cm² (nearest cm)

Answer: 1063 cm² (Answer B)

3. Classify the triangle with the given side lengths as acute, right, obtuse, 10 points
Alex_Xolod [135]

Answer:

3) Obtuse

4) Right

Step-by-step explanation:

3)

11 + 13 > 25 It is a triangle

11² + 13² = 25²

121 + 169 = 625

290 ≠ 625

Since hypotenuse is larger, the triangle is obtuse

4)

21 + 28 > 35 It is a triangle

21² + 28² = 35²

441 + 784 = 1225

1225 = 1225

Since the hypotenuse is equal to the legs, it's a Right triangle

The aircraft A330 flies at an average speed of 400 miles per hchor. The expression, 400t gives the distance traveled by the airc
Olenka [21]

The expression:

d(t)=400t

gives the distance traveled by the aircraft in t hours, so, for t = 6:

\begin{gathered} t=6 \\ d(6)=400(6) \\ d(6)=\frac{2400mi}{h} \end{gathered}

Convert into slope intercept form?
Alexeev081 [22]
<h3>Answer:</h3>

y = 2x + 5

<h3>Step-by-step explanation:</h3>

<u>Definitions</u>:

Slope Intercept form; y = mx + b

m = slope

b = y intercept

Step 1: Since the slope is given plug it into y = mx

y = 2x + b

Step 2: Plug a points' x and y into their corresponding spots to solve for b

(33) = 2(14) + b

Simplify and solve

33 = 28 + b

-28  -28

  5 = b

Plug both your slope in and your y intercept into y = mx + b

y = 2x + 5

Step-by-step explanation:

The exact question is as follows :

Given - On a​ map, 1 inch equals 5.4 miles. Two houses are 3.5 inches apart on the map.

To find - What is the actual distance between the​ houses?

Solution -

Given that,

1 inch = 5.4 miles

⇒3.5 inches = 3.5 × 5.4 miles

                 = 18.9 miles

∴ we get

The actual distance between the houses is 18.9 miles.

Please answer! Only if correct, please.
marta [7]

Answer:

f(-4) = -6

g(2) = -14

Step-by-step explanation:

To evaluate a function we must plug in the values of x. So for:

f(x) = 2x+2

we have:

f(-4) = 2(-4)+2

then we simplify:

f(-4) = -8+2

so f(-4) = -6

Now the same steps are taken for g(x) in which the answer would be -14.
