What is the weight of a square if a triangle weighs 4 grams? Explain your reasoning
Answers
Answer:
2 grams
Step-by-step explanation:
One can see that the given diagram is that of a balancing scale, meanig that both sides are equal to each other. Therefore, if one calls the weight of the triangle (t), then one can form an equation. Keep in mind that it is given that the square weighs (4) grams, and therefore, the square doesn't need a variable representation.
t + 4 + 4 = t + t + t + 4
Simplify,
t + 8 = 3t + 4
Inverse operations,
t + 8 = 3t + 4
-4 -4
t + 4 = 3t
-t -t
4 = 2t
/2 /2
2 = t
Answer:
2 grames

Answer:
[tex] \displaystyle \rm A_{ \text{c - pentagon}} =41[/tex]
[tex] \rm \displaystyle P _{ \rm c - pentagon} = 20+ 4 \sqrt{2} [/tex]
Step-by-step explanation:
we have a square and a triangle
we want to figure out the area and the perimeter of the pentagon
to figure out the area of the pentagon we can use the given formula:
[tex] \displaystyle \rm A_{ \text{c - pentagon}} = A_{ \text{squre}} - A_{ \text{triangle}}[/tex]
let's figure out [tex]A_{\rm square}[/tex]:
since the given shape is a square Every angle of its 90° Thus the triangle is a right angle triangle
therefore the height is 4
[tex] \displaystyle A _{ \rm triangle} = \frac{1}{2} \times b \times h[/tex]
substitute h and b
[tex] \displaystyle A _{ \rm triangle} = \frac{1}{2} \times 4 \times 4[/tex]
reduce fraction:
[tex] \displaystyle A _{ \rm triangle} = 2 \times 4[/tex]
simplify multiplication:
[tex] \displaystyle A _{ \rm triangle} = 8[/tex]
likewise square
[tex] \displaystyle A _{ \rm squre} = {s}^{2} [/tex]
substitute s:
[tex] \displaystyle A _{ \rm squre} = {7}^{2} [/tex]
simplify square
[tex] \displaystyle A _{ \rm squre} = 49[/tex]
hence,
[tex] \displaystyle \rm A_{ \text{c - pentagon}} =49- 8[/tex]
[tex] \displaystyle \rm A_{ \text{c - pentagon}} =41[/tex]
to figure out perimeter
let's figure out hypotenuse first
[tex] \displaystyle h = \sqrt{ {4}^{2} + {4}^{2} } [/tex]
[tex] \displaystyle h = \sqrt{ 16 + 16} [/tex]
[tex] \displaystyle h = 4 \sqrt{2} [/tex]
therefore,
[tex] \rm \displaystyle P _{ \rm c - pentagon} = 3 + 3 + 4 \sqrt{2} + 7 + 7[/tex]
[tex] \rm \displaystyle P _{ \rm c - pentagon} = 6 + 4 \sqrt{2} + 14[/tex]
[tex] \rm \displaystyle P _{ \rm c - pentagon} = 20+ 4 \sqrt{2} [/tex]

Find the value’s of x given that f(x) = x^2 - 2x - 3 and f(x) = 5
Answers
Answer:
4 and - 2
Step-by-step explanation:
f ( x ) = x^2 - 2x - 3
f ( x ) = 5
x^2 - 2x - 3 = 5
x^2 - 2x - 3 - 5 = 0
x^2 - 2x - 8 = 0
x^2 + 2x - 4x - 8 = 0
x ( x + 2 ) - 4 ( x + 2 ) = 0
( x - 4 ) ( x + 2 ) = 0
x - 4 = 0
x = 4
x + 2 = 0
x = - 2
x has 2 values,
x = 4, - 2

Answers
Answer:
Is there more to this question?
For the first inequality, x > -1
For the second inequality, x < -1
Step-by-step explanation:
5x - 29 > -34
add 29 to both sides
5x > -5
divide both sides by 5
x > -1
-----------------------------------------------------
2x + 31 < 29
subtract 31 from both sides
2x < -2
divide both sides by 2
x < -1

b) 4.7 years
Step-by-step explanation:
Attached below is the detailed solution
a) exponential statement in log form for an investment at 15% quarterly
Log ( 2 ) = 4t Log ( 83/80 )
n = 4 , r = 15
b) using change to base to find double time in yr
Double time in yr
t = Log ( 2 ) / 4log ( 83/80 )
= 4.7 years
