Answer:
B. 192.5 ft³
Step-by-step explanation:
To find the volume of a triangle prism, multiply the base, height, and length together, and then divide it by 2 (or multiply that by 0.5).
(5 * 7 * 11)/2
Multiply 5 by 7 to get 35.
(35 * 11)/2
Multiply 35 by 11 to get 385.
385/2
192.5 ft³ is the volume of this triangluar prism.
If your teacher wants you to factor, then use the difference of squares rule
9x^2 - 4
(3x)^2 - 2^2
(3x-2)(3x+2)
Answer:
4
Step-by-step explanation:
For WX to be perpendicular to YZ, then the product of their slope must be -1
For slope of WX
W(2-3) and X(-4.9),
Mwx = 9-(-3)/-4-2
Mwx = 12/-6
Mwx = -2
For slope of Y(5. y), and Z(-1, 1),
Myz = 1-y/-1-5
Myz = 1-y/-6
Since Mwx•Myz = -1
-2•(1-y/-6) = -1
1-y/3 = -1
1-y = -3
-y = -3-1
-y = -4
y = 4
Hence the value of y is 4
Answer:
no as all fractions are rational numbers and that is a mixed fraction
