To find one half of three fourths, multiply the fractions. 1/2 x 3/4. You would get 3/8. I hope this helps!
triangle on right is the same as the triangle on the left
use pythagorean theorem
hypotenuse will give to the sides of the rectangle
a^2 + b^2 = hypotenuse squared
10.4^2 = 108.16
15.3^2 = 234.09
342.25 = hypotenuse squared
take the square root in both sides
hypotenuse = the square root of 342.25 =
18.5
add up the areas of the 2 triangles and rectangle
triangle area is 1/2 times 10.4 times 15.3 =
79.56
2 triangles areas are 159.12
rectangle area is 18.5 × 7 = 129.5
159.12 + 129.5 = 288.62
answer 1 = 288.62
second question:
to get 1 side take the
square root of 702.25 which is
26.5
to get the perimeter
multiply 26.5 by 4 which is
106
answer 2 is choice B 106
Answer:
A multiplicative inverse is a reciprocal. ... A reciprocal is one of a pair of numbers that when multiplied with another number equals the number 1. For example, if we have the number 7, the multiplicative inverse, or reciprocal, would be 1/7 because when you multiply 7 and 1/7 together, you get 1!
Answer:
<h2>15</h2>
Step-by-step explanation:
Let x = m∠abc
6x-7 = 4x+23
⇔
6x - 4x = 23 + 7
⇔
2x = 30
⇔
x = 15
8x - 9y = 1
Solve for y:
-9y = -8x + 1
y = 8/9 x - 1/9
The slope of the given line is 8/9, so the slope of the perpendicular is -9/8.
y = mx + b
y = -9/8 x + b
The perpendicular passes through (3, -4).
-4 = -9/8 * 3 + b
-4 = -27/8 + b
b = -32/8 + 27/8
b = -5/8
The equation in slope-intercept form is
y = -9/8 x - 5/8
Now we change the equation to standard form.
8y = -9x - 5
The equation in standard form is
9x + 8y = -5
