Answer:
4
Step-by-step explanation:
11 + 28 - 25 - 10
39 - 25 - 10
14 - 10
4
Remember PEMDAS (Parentheses, Exponents, Multiply, Divide, Add, Subtract)
9:14 and a:7 are equal ratios 14/2=7 and 9/2=4.5 so the answer is 4.5
Answer:
x=25.63
Step-by-step explanation:
turn p into 1000.
1000= -2x^2+70x+520
Subtract 520 from both sides
1000-520= 480
480= -2x^2+70x
Apply the quadratic formula, and x=25.63
So you have to charge at least $25.63
Answer:
28
Step-by-step explanation:
83 - [59 - (22-18)]
= 83 - [59 - 4]
= 83 - 55
= 28
Answer:
The measure of all the angles are;
45°, 135°, 45°, and 135°
Step-by-step explanation:
The given parameters are;
The ratio of two adjacent angles of the parallelogram = 1:3
Let x represent one of the adjacent angles, and let y represent the other adjacent angle
Given that two adjacent angles of a parallelogram are supplementary, we have;
x + y = 180°
x:y = 1:3
Therefore, y = 3 × x = 3·x, which gives;
x + 3·x = 180°
4·x = 180°
x = 180°/4 = 45°
y = 3 × x = 3 × 45° = 135°
Given that opposite interior angles of a parallelogram are equal, we have, the measure of all the angles are;
45°, 135°, 45°, and 135°.
