Answer:

30m²

Step-by-step explanation:

To find the area of a triangle, you need to ensure that the triangle is a right-angled triangle. We can use the Pythagoras Theorem to help us prove that.

a² + b² = c²

5² + 12² = 169

13² = 169

By converse of Pythagoras Theorem, the triangle is a right-angled triangle.

Thus, you can directly find the area of the triangle using the formula: base × height ÷ 2.

Area = 12 × 5 ÷ 2

= 30m²

Answer: Love bird is 4 inches long.

Step-by-step explanation:

Given: The body of a great roadrunner is 16 in. Long and the tail is 8 in.

Also, Total length of a great roadrunner is = 4 x (length of lovebird).

It implies, length of lovebird = $\dfrac{\text{length of lovebird}}{4}$

$=\dfrac{16}{4}=4\text{ inches}$

Hence, Love bird is 4 inches long.

GIVE OUT BRAINLY 2) Kathleen is a sales associate in a jewelry store. She earns $560/wk plus an 8% commission on sales. How much

aev [14]

700<=560+0.08x

x is total sales $

the 560 is the constant weekly pay, since we're only calculating for one week.

we're adding 0.08x to account for the 8% of the total sales

solve it for x:

700-560 <= 0.08x

140 <= 0.08x

1750 <= x

or x >= 1750

meaning she needs $1750 worth of sales that week to earn atleast $700

as for C) just draw a number line with the number 1750 in the middle and the right shaded because it is 1750 or more.
