Mary always saved 45% of his salary. When his salary decreased by 20% in April, his savings decreased by $180.
How much was Mary’s salary before the decease?
Answer:
Step-by-step explanation:
Answer:
Is Mary a guy? :|
Step-by-step explanation:
I did this by just a good guess , not really the right way
2000*.45=900 ( 900 is the old savings)
2000*.2 =400 ( how much her salary went down by )
2000-400=1600 ( new salary )
1600*.45 = 720 ( 45% of new salary is new savings
900-720=180 ( change in savings is 180 , the amount the question asks for)
Mary's old salary was 2,000

Answer:
10[tex]x^{2}[/tex] -20x -12.5 inches
Step-by-step explanation:
Triangle Area Equation:
Area of triangle = [tex]\frac{1}{2} * base * height[/tex]
base = 10x + 5
height = 2x - 5
1/2 (10x + 5) (2x - 5)
= 1/2 (20[tex]x^{2}[/tex] - 50x + 10x - 25)
= 1/2 ( (20[tex]x^{2}[/tex] - 40x - 25)

Answer:
A = 54.11 unit²
Step-by-step explanation:
Given that :
A = θ/360 * πr²
A = 62/360 * π(10)²
A = 0.1722222 * π * 100
A = 54.105206
A = 54.11 unit²

Answer:
3) [tex]x^{2}[/tex] + 4x - 21
Step-by-step explanation:
(x - 3)(x + 7)
Distribute:
x(x + 7)
-3(x + 7)
x(x) = [tex]x^{2}[/tex]
x(7) = 7x
-3(x) = -3x
-3(7) = -21
Combine like terms:
7x - 3x = 4x
Put it together:
[tex]x^{2}[/tex] + 4x - 21
Answer: x²+ 4x - 21
Let's do this step-by-step.
1. Apply the foil method. (formula: (a + b)(c + d) = ac + ad + bc + bd)
F - First
O - Outer
I - Inner
L - Last
= xx + x × 7 + (-3)x + (-3) × 7
2. Apply the minus and plus rules. + (-a) = -a
xx + 7x - 3x - 3 × 7
3. Simplify.
Convert xx into a exponent.xx ⇒ x²Subtract 7 by 3.7x - 3x = 4xMultiply 3 by 7.7 × 3 = 21Hence, the answer is x² + 4x - 21

How
Many small circles of radius 7cm
can be got from big
big circle of radius
35cm
Answer:
Let get x as a number of small circles.
Area of big circle = Area of all small circles
(Here . implies multiplication)
22/7 . 35 cm .35cm = 22/7 . 7cm .7cm .x
x = (22/7 . 35 cm .35cm) / (22/7 . 7 cm .7cm)
x = (35 . 35) /(7.7)
x = 25

What is f(6)?
f(x) = 5x - 2
Answer:
f(6) = 28
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
FunctionsFunction NotationStep-by-step explanation:
Step 1: Define
f(x) = 5x - 2
f(6) is x = 6
Step 2: Evaluate
Substitute in x [Function]: f(6) = 5(6) - 2Multiplication: f(6) = 30 - 2Subtraction: f(6) = 28=========================================================
Explanation:
Everywhere you see an x, replace it with 6
f(x) = 5x - 2
f(6) = 5*6 - 2
f(6) = 30 - 2
f(6) = 28
Remember that 5x is the same as 5*x or "5 times x". So that's why 5x turned into 5*6 after replacing x with 6. After every x is replaced, you follow the order of operations PEMDAS to simplify.

Let the measure of Arc B C D = a°. Because Arc B C D and Arc B A D form a circle, and a circle measures 360°, the measure of Arc B A D is 360 – a°. Because of the ________ theorem, m∠A = StartFraction a Over 2 EndFraction degrees and m∠C = StartFraction 360 minus a Over 2 EndFraction degrees. The sum of the measures of angles A and C is (StartFraction a Over 2 EndFraction) + StartFraction 360 minus a Over 2 EndFraction degrees, which is equal to StartFraction 360 degrees Over 2 EndFraction, or 180°. Therefore, angles A and C are supplementary because their measures add up to 180°. Angles B and D are supplementary because the sum of the measures of the angles in a quadrilateral is 360°. m∠A + m∠C + m∠B + m∠D = 360°, and using substitution, 180° + m∠B + m∠D = 360°, so m∠B + m∠D = 180°.
What is the missing information in the paragraph proof?
Answer:
A. Inscribed Angle
Step-by-step explanation:
Because the angles are inscribed in the circle, the angle lie on arcs which mean that the angles have to add up to 360 degrees just like a circle is 360 degrees, making it a quadrilateral that is inscribed!
The missing information in the paragraph proof should be considered as the Inscribed Angle.
What is Inscribed Angle?In terms of geometry, an inscribed angle should be the angle that should be created in the interior of a circle at the time when two chords intersect on the circle. Since the angles should be inscribed in the circle so here the angles should be added up to the 360 degrees same as like the circle also at the same time it should make the quadrilateral
Therefore, The missing information in the paragraph proof should be considered as the Inscribed Angle.

One Classroom has a volume of 564 cubic feet. Another classroom measure 17 feet tall , 8 feet long , and 5 feet wide. How much bigger is the volume of the second classroom compared to the first ?
Answer:
Step-by-step explanation:
Let d=difference. V=xyz
d=17(8)5-564
d=680-564
d=116 ft^3
So the second classroom is 116 cubic feet larger than the first.
The ratio of boys to girls in a class is 5:7. There are 36 students in the
class. How many more girls than boys are there?
Answer: number of girls = 21 & number of boys = 15
21 - 15 = 6 ( the difference is 6 )
Step-by-step explanation:
Answer:
add the ratios together. this gives 5+7 which is 12. divide 36 by 12, this gives 3. this tells us it's three students for every value of the ratio, so the ratio is 5(3):7(3). it becomes 15 boys to 21 girls. to find out how many more girls, we subtract 15 from 21. our answer is 6.

standard form. х + 9 х + 3
Answer:
10x+3, or 2x+12, or [tex]x^{2}[/tex]+12x+27
Step-by-step explanation:
If the equation is x + 9x + 3, combine like terms you get 10x+3
If the equation is x+9 + x+3, combine x and numbers (like terms) and you get 2x+12
If the equation is (x+9)(x+3) or it is asking you to multiply, multiply x by x, and 9 by x, and 3 by x, and 9 by 3. Add them all up (like terms) and you get [tex]x^{2}[/tex]+12x+27.
