Vasco needs to know the area of the four-pointed star

Mathematics
1 answer:
Rama09 [41]2 years ago
7 0

Answer:

Step-by-step explanation:

Find the area of the base

The base is a square.

The formula is Area = s^2

s = 1.5

Area = 1.5^2

Area = 2.25 sq cm.

Area of 1 triangle

h = 2.4

b = 1.5

Area = 1/2 * b * h

Area = 1/2 * 1.5 * 2.4

Area = 1.8 cm^2

Area of 4 triangles

Area = 4 * area of 1 triangle

Area = 4 * 1.8

Area = 7.2

Total Area = 2.25 + 7.2 = 9.45 cm^2

jeyben [28]

Answer:

$51,557.00

Step-by-step explanation:

1100 times 9% = 99 a year

99 times 43 = 4257

1100 times 43 =47,300

then you add 47,300 + 4257 = 51,557

you take your total that she put into the ira and multiply it by 9%

then you multiply that total by the number of years before she retires which is 43

so 99 times 43 = 4257

then you will multiply how much she put in the ira at the beginning of the year which is 1100 by the 43 years before she retires which is 47,300

then you add your totals together

4257 + 47,300 = 51,557

How to find the why intercept when the Slope 2 points pass through (4,13)
ozzi

Answer:

The y-intercept is (0, 5).

Step-by-step explanation:

We find the equation of the line in slope-intercept form:

y - y1 = m(x - x1)

y - 13 = 2(x - 4)

y = 2x - 8 + 13

y = 2x + 5  -  This is slope-intercept form where the graph passes through the y-axis at y = 5.
