Answer:
5
Step-by-step explanation:
when dividing number by fractions,we can simply multiply the number by the reciprocal of the decimal
so,4÷1/5=4 ×(reciprocal of 1/5 )
A reciprocal of a number is the same no.written under 1 aka.1divided by that number which simply is flipping
numerator and denominator .
reciprocal of 1/5 is 5/1 =5
so 4÷1/5 = 4×5
so answer is 5

Answer:
Step-by-step explanation:
Given
Required
Find all product of real values that satisfy the equation
Cross multiply:
Subtract 7 from both sides
Reorder
Multiply through by -1
The above represents a quadratic equation and as such could take either of the following conditions.
(1) No real roots:
This possibility does not apply in this case as such, would not be considered.
(2) One real root
This is true if
For a quadratic equation
By comparison with
Substitute these values in
Add 56 to both sides
Divide through by 4
Take square roots
Hence, the possible values of r are:
or
and the product is:
Answer: 66 degrees
Explanation.
Complementary angles add up to 90 degrees.
Because one angle is 24 degrees, the other angle is
90 - 24 = 66 degrees.
Answer:
532
Step-by-step explanation:
Sqr = 324
Tri - .5 * 16 * (8+18)
Sqr + Tri
Answer:
3. One Solution. (0,4). (they have different slopes and y-intercepts)
The solution can be found using elimination method:
Add the equations together
y = -x + 4
y = x - 4
2y = 0
y = 0
Solve for x
0 = x - 4
x = 4
(4, 0)
4. No solution
x + y = -2 and 3 which is not possible
The two lines would be parallel
