Michael needs to wrap a gift that is shaped like a triangular pyramid. Each face has an area of 25 in². What is the surface area? (Hint: Figure out how many faces a triangular pyramid has)
If the answer is 75 ft², color is black if the answer is 100 in², color is red
A triangular pyramid is a pyramid having a triangular base. It has 4 faces, 6 edges and 4 vertices.
Since the area of one face is 25 [tex] in^{2} [/tex]
Therefore, surface area of triangular pyramid = 4 [tex] \times [/tex] area of one face
= [tex] 25 \times 4 [/tex]
= 100 [tex] in^{2} [/tex].
So, the surface area of triangular pyramid is 100[tex] in^{2} [/tex].
Therefore, color is red.
What is the sum of (7x-6y) and (x + y)
We have to find the sum of (7x-6y) and (x+y)
(7x-6y) and (x+y) are two Algebraic expressions
Sum of two algebraic expressions is also a algebraic expression
So, (7x - 6y) + (x+y) = 7x - 6y + x + y
= 7x + x + y - 6y
= x (7 + 1) + y - 6y
= 8x + y - 6y
= 8x + y ( 1 - 6 )
= 8x + y ( -5 )
= 8x - 5y
Hope this helps..!!
Thank you :)
What is 312.501 rounded to the nearest whole number? A. 310 B. 311 C. 312 D. 313
In mathematics, the principle of rounding instructs us to look at the decimal part . If it's .5 or higher, we round up; if it's less than .5, we round down. Hence, 312.501 rounded to the nearest whole number is 313.
Explanation:The question pertains to the concept of rounding numbers. In mathematics, rounding means replacing a number with an approximate value that has a shorter, simpler, or more explicit representation. To round 312.501 to the nearest whole number, we look at the decimal part of the number. If the decimal is .5 or greater, we round up; if it's less than .5, we round down. In this case, the decimal part is .501, so we round up to the next whole number.
So, 312.501 rounded to the nearest whole number is D. 313.

Answer:
If two secant segments intersect outside a circle, then the product of one secant segment with its external portion equals the product of the other secant segment with its external portion. So we have:
10(10) = 5(3x + 5)
100 = 15x + 25
15x = 75
x = 5
