Answer:
3/4 × 2/5 = 3/10
Step-by-step explanation:
3/4 × 2/5 is equivalent to 3/4 of 2/5
First, you have to divide the number line in 5 parts, and locate 2/5 (see figure attached)
Next, you have to divide in 4 parts the segment that represents 2/5, and locate 3/4 of 2/5
If you continue dividing the whole line with the previous segment length, you will divide the whole line into 10 parts.
Then, 3/4 of 2/5 is 3/10.
Answer:
B. 12
Step-by-step explanation:
✔️Find the value of x
The side lengths of two similar triangles are always proportional.
Given that ∆ABC ~ ∆LMN, therefore:
AB = 5
LM = 10
AC = x + 5
LN = 3x + 3
Plug in the values
Cross multiply
(distributive property)
Collect like terms
Divide both sides by 5
x = 7
✔️Find AC
AC = x + 5
Plug in the value of x
AC = 7 + 5
AC = 12
Answer:
B. The other solution to function is
.
Step-by-step explanation:
From Algebra, we remember that quadratic functions of the form has solutions of the form:
, where both are complex if and only if
.
Hence, if one solution of the quadratic function is , then the other solution is
. The correct answer is B.
