Step-by-step explanation:
im pretty sure ur supposed to find so the answer woild be c=0.8
Answer:
In this equation X is independent variable while Y is dependent variable.
Step-by-step explanation:
Equation:
Y=10x+100
Independent variable in math:
A variable in an equation that may have its value freely chosen without considering values of any other variable.
Dependent variable in math:
A dependent variable is a variable in an expression, equation, or function that has its value determined by the choice of value of other variable.
<u>According to above definitions Y is dependent of x. As we changes the value of x the value of Y changes.</u>
For example if x = 1, Y will be 110.
And if x = 10, Y will be 200.
Answer:
280cm squared
Step-by-step explanation:
By adding a 2cm wooden board, Gavin is adding 4 cm to each side, os the new sides would be 14 and 20. 14*20=280 cm squared.
Answer:
Three-fourths
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
∠QSR≅∠XZY ---> given problem
∠QRS≅∠XYZ ---> given problem
so
△QRS ~ △XYZ ----> by AA Similarity theorem
Remember that, if two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
That means
∠Q≅∠X
∠R≅∠Y
∠S≅∠Z
<em>In the right triangle XYZ</em>
Find the tangent of angle X
---> opposite side angle X divided by adjacent side angle X
substitute the given values
Simplify
Remember that
∠Q≅∠X
so
therefore
---->Three-fourths
the first picture you have to use B X L X H ( base, length and height) and i got 1728 mm^3
for the second one, you have to use the formula L X H ( P+ Q/2) ( length times height times the product of the base width plus the top width divided by 2 and i got the answer of 196 m^3.
i hope this helps :)
