Find the area of the triangle SHOW WORK

kykrilka [37]

Answer:

The area of triangle is 1263.6 mm².

This is an Equilateral triangle.

Step-by-step explanation:

Given that the area of triangle formula is A = 1/2×base×height. So you have to substitute the values into the formula :

$area = \frac{1}{2} \times base \times height$

Let base = 54mm,

Let height = 46.8mm,

$area = \frac{1}{2} \times 54 \times 46.8$

$area = \frac{1}{2} \times 2527.2$

$area = 1263.6 \: {mm}^{2}$

This is the Equilateral triangle because all sides of the triangle are equal.

In a certain year, the population of Smallburg was $4{,}000.$ In the following year, the population increased by $15\%.$ What wa

makkiz [27]

Answer:

4,600

Step-by-step explanation:

To solve this problem, we need to multiply add 15% of 4,000 back to 4,000.

First, change 15% into a decimal:

15% -> $\frac{15}{100}$ -> 0.15

Next, multiply 4,000 by 0.15:

$x= 4,000(0.15)$

$x=600$

The last step is to add the 600 back to 4,000:

$4,000 + 600 = 4,600$

The population of Smallburg the following year was 4,600.
