Multiply both by 2,and you have 6/10 which is equivalent to 3/5.
Answer: D.
Step-by-step explanation: it’s D because when you do the volume of mode A, you get 48 units. When you do the volume of model B you get 40 units. Use the formula V=length x width x height!
Answer:
x = -3
Step-by-step explanation:
Since they give you the function in binomial factor form, it is very straight forward to find what its zeroes are: Those x-values for which any of the binomial factors renders zero would be a so called "zero" of the function.
We examine each of these binomial factors [ (x+3), (x-7) and (x+5) and notice that for the factor:
(x+3) to be zero, x needs to be equal to "-3",
(x-7) to be zero, , x needs to be equal to "7",
(x+5) to be zero, , x needs to be equal to "-5".
therefore, from the options they give you, only "x= -3" is correct.
Answer:
13 and -13
Step-by-step explanation:
The only factors of 169 are 1, 13, and 169.
Since the product is negative, you have to use 13 and -13. These numbers have a difference to 26. And when multiplied they equals -169
There were 11 birds at the shelter on Wednesday.
Step-by-step explanation:
Cost of care for one bird = $4.00
Cost of care for one cat = $8.00
Total spent = $148.00
Total birds = 24
Let,
Number of birds = x
Number of cats = y
According to given statement;
x+y=24 Eqn 1
4x+8y=148 Eqn 2
Multiplying Eqn 1 by 4
Subtracting Eqn 3 from Eqn 2;
Dividing both sides by 4
Putting y=13 in Eqn 1
There were 11 birds at the shelter on Wednesday.
