Answer:
280 ft³
Step-by-step explanation:
Volume of the prism will be ,
=> V= Base area × height .
The base is a triangle , so ,
=> V = 1/2 * 7*8 * h
=> V = 28 * h
Here height is 10ft , so
=> V = 28 * 10
=> V = 280 ft³
Answer:
Angles are 3x, 4x = 
Angles from lowest to highest: 
Step-by-step explanation:
Given: Two angles of a quadrilateral measure 140° and 80°. The other two angles are in a ratio of 3:4.
To find: value of x, measures of those two angles and
Also, to list the measures of the other two angles from lowest to highest.
Solution:
According to angle sum property of a quadrilateral, sum of angles of a quadrilateral is 180°.
Let the two angles be 3x and 4x

So, angles are as follows:

Angles from lowest to highest: 
9514 1404 393
Answer:
41 13/40
Step-by-step explanation:
Generally, you're told to multiply mixed numbers by converting each to an improper fraction:
5 7/10 = (5·10 +7)/10 = 57/10
7 4/16 = (7·16 +4)/16 = 116/16
The fractions are multiplied by multiplying their numerators to get the numerator of the result, and multiplying their denominators to get the denominator of the result.

__
You don't have to mess with reducing the fraction of the result if you reduce the fraction 4/16 to 1/4 to begin with. Then the product is (57/10)(29/4).

You can also treat this as the product of two sums. The distributive property is handy for this.
(5 + 7/10)(7 + 1/4) = (5)(7) +(5)(1/4) +(7/10)(7) +(7/10)(1/4)
= 35 +5/4 +49/10 +7/40
= 35 +1 +1/4 + 4 + 9/10 + 7/40 . . . . take out the integer parts
= 40 +10/40 +36/40 +7/40 . . . . . . use 40 as a common denominator
= 40 +53/40 = 41 13/40
