Answer:
- C. V = 15 x 4.2
- D. V = 7.5 x 2 x 4.2
Step-by-step explanation:
The volume is the product of the three dimensions, so can be figured as ...
7.5 × 2 × 4.2 . . . . choice D
Carrying out the first multiplication, this will be equivalent to ...
15 × 4.2 . . . . . . . . choice C
The area of the triangle is 90 m²
Explanation:
Given that the base of the triangle is 15 m
The altitude of the triangle is 12 m
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,
where b is the base and h is the altitude
Thus, we have,
and 
Substituting the values in the above formula, we get,
Multiplying the terms, we get,
Dividing, we get,
Therefore, the area of the triangle is 90 m²
Put the equation in y=mx+b format
Y=-4x-3y
Y+3y=-4x
4y=-4x
Y=-4/4x
Y=-x
The slope is -1

Answer:
C
Step-by-step explanation:
Stay safe hope this helps
x + y = 24 where x and y are the 2 parts of diagonal Other diagonal wil be smaller that 24.
x^2 + z^2 = 13^2
y^2 + z^2 = 20^2 where z = 0.5 * length of smaller diagonal)
form last 2 equations
y^2 - x^2 = 20^2 - 13^2 = 231
now y = 24-x so we have
(24 - x)^2 - x^2 = 231
576 - 48x = 231
48x = 345
x = 7.1875
z^2 = 13^2 - 7.1875^2 = 117.34
z = 1.83
so smaller diagonal = 21.66 cm
looks like its the third choice.
