Answer:
Volume: 105 cubic centimeters
Mass of doorstop: 924 grams
Step-by-step explanation:
First, you need to find the area of the triangular base of the prism. The area of the triangle is bh/2=10*6/2=30 square centimeters. Multiplying this by the height of the doorstop of 3.5, you get a total volume of 105 cubic centimeters. Since each cubic centimeter weighs 8.8 grams, the whole thing weighs 105*8.8=924 grams. Hope this helps!
Answer:
volume 105 cm³
mass 924 g
Step-by-step explanation:
This is triangular prism so (Volume) V = (Area of base) B * (Height) H
In this case is triangle is the base shape with base b =10cm and height h= 6cm so
B =1/2 bh = 1/2 *10*6 =30 cm²
(Height) H = 3.5 cm
so V = 30*3.5 = 105 cm³
1 cm³ has a mass ≈ 8.8g
so the mass of the doorstop is volume * mass per cm³
105 * 8.8 = 924 g

Answer:
32.63 F
Step-by-step explanation:
The function:
represents sound travels s at feet per second, where t is the temperature at Fahrenheit degrees.
We know that sound traveled at a rate of 1121 ft/sec. To find the temperature we need to replace with s value and isolate t for the above function.
multiply 2nd row by -1 and add to first row
divide the 1st row by 2
multiply the first row by -1 and add to 2nd row
now we know
y+3=0
x-2=0
therefor
y=-3
x=2
