Answer:
56 gray chairs
24 blue chairs
Step-by-step explanation:
ratio of gray to blue chairs in each row
Gray : blue = 7 : 3
Gray chairs = 7
Blue chairs = 3
Total ratio = 7 + 3
= 10
how many gray chairs and blue chairs will julio use if he sets up a total of 80 chairs
Number of gray chairs = 7/10 × 80
= 0.07 × 80
= 56 gray chairs
Number of blue chairs = 3/10 × 80
= 0.03 × 80
= 24 blue chairs
56 gray chairs
24 blue chairs
Answer:
A
Step-by-step explanation:
The degree is cubic (3) and there are 3 terms X^3, X^2, X
Answer:
9/8
Step-by-step explanation:
add - 1/2 to both sides giving you p
but to you need to find like terms so
times 1/2 by 4
4/8 + 5/8 = 9/8
Secant and tangent theorem: Square of measure of tangent is equal to the product of length of whole secant and length of exterior secant segment, i.e.
.
The whole secant wuth exterior secant 4 cm is 4+x cm. Tangent is 7 cm. Using previous theorem, you can get that
.
Solve this equation:
cm.
Answer: x=8.3 cm.
Answer:
The value of given function for x = - 3 is 9
Step-by-step explanation:
Given as :
The y is the function of x is as
f( x ) = x²
So, For any value of x , the value of f( x ) should change
If, x = - 3
So, f ( - 3 ) = ( - 3 )²
Or, f ( - 3 ) = ( - 3 ) × ( - 3 )
i.e f ( - 3 ) = ( - × - ) ( 3 × 3 )
Or, f ( - 3 ) = ( + ) ( 9 )
∴ f ( - 3 ) = 9
So, The value of function f ( - 3 ) = 9
Hence , The value of given function for x = - 3 is 9 Answer
