Answer:
Square is 90 degree angle
Step-by-step explanation:
Given:
The table of values is
Number of Students : 7 14 21 28
Number of Textbooks : 35 70 105 140
To find:
The rate of change and showing that the ratios of the two quantities are proportional and equivalent to the unit rate.
Solution:
The ratio of number of textbooks to number of students are




All the ratios of the two quantities are proportional and equivalent to the unit rate.
Let y be the number of textbooks and x be the number of students, then

Here, k=5.


Hence the rate of change is constant that is 5.
Answer:
The interest generated will be $ 51.20.
Step-by-step explanation:
To determine the compound interest on the account with 0.01% interest rate in 5 years compounded quarterly with an initial deposit of $ 1,000, the following calculation must be performed:
1,000 x (1 + 0.01 / 4) ^ 4x5 = X
1,000 x (1 + 0.0025) ^ 20 = X
1,000 x 1.0025 ^ 20 = X
1,000 x 1.05120 = X
1,051.20 = X
1,051.20 - 1,000 = 51.20
Therefore, the interest generated will be $ 51.20.
Answer:
100 x 13/16 x 25b = 4
18 3/4 = 25b/4
b=25/4
b= 6.25
Step-by-step explanation:
25/4 = 6 1/4 last weekend and 18 3/4 this weekend.
<u><em>Answer: x=-17 and -17=x. *The answer should be the negative sign.*</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
a-c=b-c
subtract by 5 both sides of an equation.
x+5-5=-12-5
simplify.
12+5=17
17-5=12
17-12=5
x=-17 and -17=x
Hope this helps!
Thanks!
Have a great day!
