Answer: 140 cubic inches

Step-by-step explanation:

The formula for determining the volume of a rectangular base pyramid is expressed as

Volume = 1/3 × base area × height

From the information given,

Length = 7 inches

Width = 3 inches

Base area = 7 × 3 = 21 square inches

Height = 12 - 4 = 8 inches

Volume = 1/3 × 21 × 8 = 56 cubic inches

The formula for determining the volume of a rectangular prism is expressed as

Volume = Length × width × height

Volume = 7 × 3 × 4 = 84 cubic inches

Volume of the composite figure is

56 + 84 = 140 cubic inches

Could a quadrilateral have 4 obtuse angles
Alex73 [517]
No because all quadrilaterals must equal a total of 360 degrees. If you have four angles that are greater than 90 degrees the sum of all the interior angles is greater than 360 degrees therefore it cannot exist as a quadrilateral.

Find the average rate of change of each function on the interval specified.
ExtremeBDS [4]

The average rate of change (AROC) of a function f(x) on an interval [a, b] is equal to the slope of the secant line to the graph of f(x) that passes through (a, f(a)) and (b, f(b)), a.k.a. the difference quotient given by

f_{\mathrm{AROC}[a,b]} = \dfrac{f(b)-f(a)}{b-a}

So for f(x) = x² on [1, 5], the AROC of f is

f_{\mathrm{AROC}[1,5]} = \dfrac{5^2-1^2}{5-1} = \dfrac{24}4 = \boxed{6}

two angles are supplementary of the sum is 180. the larger angle measures four degrees more than sevem times the measure of a sm
Aleksandr [31]

Answer:

22 and 158

Step-by-step explanation:

Supplementary angles add to 180. This is means there is a small and large angle. Adding together, they make 180.

  • "the larger angle measures four degrees more than seven times the measure of a smaller angle" is represented as 7x+4.
  • "x represents the measure of the smaller angle" is represented as x.

x + 7x+4 =180

8x+4=180

8x=176

x= 22

This is the measure of the smaller angle. The larger angle is 7(22)+4 = 158
