Answer:
C
Step-by-step explanation:
Ms. Barcht's savings account can be modeled with the expression
50 + 25x
Mrs. Greene's savings account can be modeled with the expression
75x
Since the question is how many weeks Mrs. Greene will have more money than Ms. Bracht. we use an inequality to contain the all the solutions.
Mrs.Greene > Ms. Bracht
75x > 25x + 50
Answer:
Discriminant = 93, two real roots/solutions
Step-by-step explanation:
Discriminant = b² - 4ac = (9)² - 4(3)(-1) = 81 + 12 = 93
Since 93>0, the quadratic equation has two real roots/solutions.
Answer: The operation preformed is multiplication.
Step-by-step explanation: When you have a integer that is raised to a power, you must evaluate that integer first. For example, if you are asked to solve 2^3 + 4^7, you must first multiply. 2^3= 8 and 4^7= 16,384 then we must add these two products together to get 16,392.
How to find the product of to the power number: 8^3. We take eight and times it by it's self 3 times to get 512.
Hope this helps!
Answer:
98
Step-by-step explanation:
there are 12 inches in one foot so if 5x12=60
12x8=96
Step-by-step explanation:
a/q both the traingles are similar/congruent so,
theri angles also have equal value
angle Q = angle A
so,
apply angle sum property of triangle in ∆PQR
so according to it
Angle
P + Q + R = 180
→ 45° + 15° + Q = 180
→ 60° + Q = 180
→ Q = 180 - 60 = 60°
→ angle Q = 60°
therefore, angle A = 60°
Angle R = angle B
so,
angle B = 15°
as, angle P = angle C
so,
angle C = 45°
