Answer:
84 cm³
Step-by-step explanation:
The volume of a pyramid is given by the formula ...
V = 1/3Bh
where B is the area of the base.
__
The base is shown as a right triangle with legs 8 cm and 7 cm. Its area is given by the triangle formula ...
A = 1/2bh
A = 1/2(8 cm)(7 cm) = 28 cm²
Then the volume of the triangular pyramid is ...
V = 1/3(28 cm²)(9 cm) = 84 cm³
Answer:
<u>x=90</u>
Step-by-step explanation:
<em />
<em>Let's solve your equation step-by-step.</em>
x/9−5=5
<em>Step 1: Simplify both sides of the equation.</em>
x/9−5=5
1/9x+−5=5
1/9x−5=5
<em>Step 2: Add 5 to both sides.</em>
1/9x−5+5=5+5
1/9x=10
<em>Step 3: Multiply both sides by 9.</em>
9*(1/9x)=(9)*(10)
x=90
Answer:
<u>x=90</u>
Answer:
(7m−3)(7m−3)
Step-by-step explanation:
Factor 49m2−42m+9
49m2−42m+9
=(7m−3)(7m−3)
The Answer is 181.688312 Because if you Use the ladder Method
We set up a proportion: 14/?= 1/5
Cross multiply: 1*?= 14*5
⇒ ?= 14*5/1= 70
1/5 of 70 is 14.
