Answer:
32%
Step-by-step explanation:
To find the percentage, we have to multiply 25 and 8 by 4.
25x4 = 100
8x4 = 32
So, 8 out of 25 is 32%.
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=Kx
where
K is the constant of proportionality or slope of the linear equation
In this problem
x ----> is the number of months
y -----> is the total amount savings
we have the ordered pairs
(4,80) and (7,140)
so
Find the value of K
K=y/x
For (4,80)
K=80/4=20
For (7,140)
K=140/7=20
The value of K is the same for both ordered paits
that means------> is a proportional relationship
therefore
the linear equation is
y=20x
the answer is the option A, C and D

Answer:
a. 12 cm
b. 90°
c. 60°
Step-by-step explanation:
The relevant relationships are ...
- all sides of a rhombus have the same length
- the diagonals of a rhombus are perpendicular bisectors of each other
- the diagonals of a rhombus divide the figure into 4 congruent triangles
__
a) The perimeter, 48 cm, is the sum of four equal side lengths, so any given side is (48 cm)/4 = 12 cm.
GH = 12 cm
__
b) Angle EJF is where the diagonals meet. It is a right angle.
∠EJF = 90°
__
c) Angle EFJ is the complement of the one marked, so is 30°. Angles EHJ and GHJ are congruent to that, so both are 30°. Angle EHG is the sum of those two congruent 30° angles, so is ...
∠EHG = 60°
Answer:
7x + 33 -I could be wrong I'm not an expert in maths jus trying to help
Step-by-step explanation:
x + 13 9x-7
so first you need to times both by two because there are two of both sums
2(x+13) so you times both numbers by 2 so
= 2x+26
and do the same with 9x - 7 so
2(9x-7) = 18x - 14
and then you add them together and find the like terms.
Like terms means for example in the equation:
2x + 3x - 4 + 3
the like terms are the two numbers that are the same like 2x and 3x are the same since they are both the same term and since there is a plus sign before the 3x you add them so 5x and then you need to do -4 + 3 = 7 and so the answer is 5x + 7.
In this case its:
2x + 26 + 5x + 7. So the like terms are 2x and +5x and +26 and +7.
So 2x + 5x = 7x and 26 + 7 = 33.
So the final equation is 7x + 33
Hope this helps :D
