You buy a shirt on sale for $20. This
sale price is 20% off the original price.
How much was the original price of
the shirt?
Answer:
$25
Step-by-step explanation:
Let the original cost of the shirt be x, therefore the sale price would be the original minus the 20% of the original price x - 0.20x = $20. Solve for x: 0.8x = 20 --> x=$25

What is the equation of the line that passes through the point (-4,4) and has a
slope of 3/4 ?
Answer:
y = 3/4x + 7
Step-by-step explanation:
Put it in point-slope form:
y - 4 = 3/4(x - -4)
y - 4 = 3/4(x + 4)
y - 4 =3/4x + 3
y = 3/4x + 7
HELP PLEASE!!! BRAINLEIST +50 PTS
Answer:
1. No, Lin is incorrect. If you change both numbers to regular notation, you get that Panama has 4,000,000 residents, and Thailand has 70,000,000 residents. 4 million times 20 is 80 million, not 70 million.
2. 10^8. You need to put 10 to the 8th power because 1 × 10^7 is too little, so it is the next power to use that isn't too small
3. Label each increment 10^7, 2 × 10^7, 3 × 10^7... 9 × 10^7, 10^8.
4. Panama's point would be located 2/5 of the way between 0 and 10^7. Peru's point would be located 1/5 of the way between 3 × 10^7 and 4 × 10^7. Thailand's point would be located right on 7 × 10^7.

Answer:
Step-by-step explanation:
A B
definition of a parallelogram a quadrilateral with both pairs of opposite sides parallel
five properties/theorems for parallelograms opposite sides are parallel, diagonals bisect each other, opposite sides are congruent, opposite angles are congruent, consecutive angles are supplementary
definition of a rectangle a quadrilateral with four right angles
rectangle theorems if a parallelogram is a rectangle, then its diagonals are congruent; if the diagonals of a parallelogram are congruent, then the paralellogram is a rectangle
five properties of a rectangle opposite sides are congruent and parallel; opposite angles are congruent; consecutive angles are supplementary; diagonals are congruent and bisect each other; all four angles are right angles
definition of a rhombus a quadrilateral with four congruent sides
rhombus theroems the diagonals of a rhombus are perpendicular; if the diagonals of a parallelogram are perpendicular, then the paralellogram is a rhombus; each diagonal of a rhombus bisects a pair of opposite angles
properties of a rhombus all parallelogram properties apply; all four sides are congruent; diagonals are perpendicular; the diagonals bisect opposite angles
definition of a square a quadrilateral with four right angles and four congruent sides
properties of a square the properties of a rectangle plus the properties of a rhombus; four right angles; all four sides are congruent
definition of a trapezoid a quadrilateral with exactly one pair of parallel sides
definition of an isosceles trapezoid a trapezoid with the legs congruent
isosceles trapezoid theroems both pairs of base angles are congruent; the diagonals are congruent
trapezoid median theorem the median of a trapezoid is parallel to the bases and its measure is one-half the sum of the measures of the bases, or median=1/2(x+y)
in these quadrilaterals, the diagonals bisect each other paralellogram, rectangle, rhombus, square
in these quadrilaterals, the diagonals are congruent rectangle, square, isosceles trapezoid
in these quadrilaterals, each of the diagonals bisects a pair of opposite angles rhombus, square
in these quadrilaterals, the diagonals are perpendicular rhombus, square
a rhombus is always a... parallelogram
a square is always a... parallelogram, rhombus, and rectangle
a rectangle is always a... parallelogram
a square is never a... trapezoid, because trapezoids only have one pair of parallel sides
a trapezoid is never a... parallelogram, rhombus, rectangle, or square, because trapezoids only have one pair of parallel sides
these quadrilaterals always have all four congruent sides rhombus, square
these quadrilaterals always have all four right angles rectangle, square
these quadrilaterals always have perpendicular diagonals rhombus, square
if you divide a square into four right triangles by drawing its two diagonals, the measure of each of the angles in the triangles that is not a right angle is... 45 degrees
the diagonals of a rhombus... are not always congruent, but they are always perpendicular and they do always bisect each other, and they do always bisect the pairs of opposite angles
the diagonals of a rectangle... are not always perpendicular, but they are always congruent and they always bisect each other
the diagonals of a parallelogram... always bisect each other
Answer:
squares, rectangles, trapeziods (only if isoceles)
Step-by-step explanation:
Squares are rectangles and rectangles always will have diagonals that are congruent. Trapezoids, if isoceles, will have congruent diagonals.

What is the volume of a cylinder, in cubic m, with a height of 6m and a base diameter
of 18m? Round to the nearest tenths place.
Answer:V= 1526.8m3
Step-by-step explanation: pi (9)2(6)
A cylinder is a three-dimensional structure formed by two parallel circular bases. The volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.
What is a cylinder?A cylinder is a three-dimensional structure formed by two parallel circular bases connected by a curving surface. The circular bases' centres overlap each other to form a right cylinder.
Given the height of the cylinder is 6m, while the base diameter is 18m. Therefore, the volume of the cylinder can be written as,
Volume of cylinder = (π/4)×d²×h = (π/4)×18²×6 = 1526.814m³
Hence, the volume of a cylinder, in cubic m, with a height of 6m and a base diameter of 18m is 1526.814.

Which function has a greater speed, and what is the greater speed?
Answer:
B. function 13 meters per second
Step-by-step explanation:
Answer:
B) Function A; 14 mps
Step-by-step explanation:
Function B has a speed of 13/s
If you look at Function A and divide the right column by the corresponding values in the left column, you get 14 every time. That is the rate of Function A.
14>13.. so Function A is faster

Give the coordinates of the point that would divide AB into a ratio of 2:1. A(4,4) B(2,-5)
Answer:
(10/3, 1)
Step-by-step explanation:
Give the coordinates of the point that would divide AB into a ratio of 2:1. A(4,4) B(2,-5)
The formula for calculating the coordinate of a point divided in the ratio a:b is expressed as;
X = ax1+bx2/a+b
Y = ay1+by2/a+b
Given the coordinates A(4,4) B(2,-5) divided in the ratio 2:1
X = 2(4)+1(2)/2+1
X = 8+2/3
X = 10/3
Similarly;
Y = 2(4)+1(-5)/2+1
Y = 8-5/3
Y = 3/3
Y = 1
Hence the required coordinate is (10/3, 1)

If one yard of fabric costs $1.70 and Polly needs 4½ yards, how much will she spend on pink fabric? Show your work!
Answer:
$7.65
Step-by-step explanation:
Okay, this is a standard multiplication problem, so:
4 1/2 x 1.7 = 7.65
Polly will spend $7.65 on pink fabric
hope this helps:)
Answer:
$7.65
Step-by-step explanation:
cost for 1 yard=$1.70
cost for 1/2 yard=$0.85
so cost for 4 and half yard will be
= 4*1.70+0.85
=6.8+0.85
=$7.65
solve the system by substitution y+X=3 2y+x=-5
Answer:
Step-by-step explanation:
We have the system:
y+x=3
2y+x=-5
the question asks us to solve by substitution..
Let's subtract y from both sides of the first equation
y+x=3
-y -y
x=3-y
now, let's substitute 3-y as x into the second equation
2y+3-y=-5
combine like terms
y+3=-5
subtract 3 from both sides
y=-8
so the value of y is -8
now let's use that information to solve for x; we know that x is 3-y, so let's substitute the value of y to find x
x=3-y
x=3--8
x=11
the value of x is 11
as a point, your answer is (11,-8)

Jenny's great-grandmother is 86 years old. Jenny is 11 years old. What percent of Jenny's great-grandmother's age is Jenny's age
Answer:
12.79%
Step-by-step explanation:
Let :
Great grand mother = 86 years
Jenny = 11 years
Let the percentage = x
x % of great grandmother's age = Jenny's age
x% * 86 = 11
x/ 100 * 86 = 11
86x / 100 = 11
86x = 100 * 11
86x = 1100
x = 1100/86
x = 12.79
x = 12.79%
