area of triangle =1/2 ×base×height=1/2×20.4×14.6=148.92in²
Area of the given shapes are:
parallelogram: 148.2yd²Rectangle: 193.52 ft²Semicircle: 760.265 in²triangle: 148.92 in²What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, Four shapes and we need to calculate the area.
For parallelogram:
area of parallelogram = base×height
area of parallelogram = 19×7.8 = 148.2yd²
For, Semicircle:
area of semi circle= 1/2 [π(d/2)²]
area of semi circle= π×44²/8 = 760.265 in²
For Rectangle:
area of rectangle = length ×breadth
area of rectangle = 16.4×11.8 = 193.52 ft²
For triangle:
area of triangle = 1/2 ×base×height
area of triangle = 1/2×20.4×14.6 = 148.92in²

Write an equation in slope-intercept form of the line that passes through the given points
Answers
Answer:
y = - [tex]\frac{4}{3}[/tex] x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = [tex]\frac{-1-3}{0+3}[/tex] = - [tex]\frac{4}{3}[/tex]
The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1
y = - [tex]\frac{4}{3}[/tex] x - 1 ← equation of line

Answer:
x = 2 and -4
Step-by-step explanation:
(x + 1)² = 9
First, take the square root of both sides. This will eliminate the square on the left side.
(x + 1) = √9
Note that √9 can be 3 or -3.
Let's write out both possibilities.
(x + 1) = 3
(x + 1) = -3
Solve.
(x + 1) = 3
[subtract 1 from both sides]
x = 2
--
(x + 1) = -3
[subtract 1 from both sides]
x = -4
Your answers are 2 and -4.
Let's check our answers by plugging in the values back into the original equation.
(x + 1)² = 9
(2 + 1)² = 9
(3)² = 9
9 = 9
That solution is correct.
(x + 1)² = 9
(-4 + 1)² = 9
(-3)² = 9
9 = 9
That solution is also correct.
Your answer is correct.

In circle J with m \angle HJK= 50m∠HJK=50 and HJ=16HJ=16 units, find the length of arc HK. Round to the nearest hundredth.
Answers
Answer:
13.96
Step-by-step explanation:
length of an arc = theta/360 * 2πr
Given
m<HJK = 50
HJ = 16units
Required
length of arc HK
arc HK = 50/360 * 2(3.14)(16)
arc HK = 5/36 * 100.48
arc HK = 502.4/36
arcHK = 13.96
hence the length of arcHK to nearest hundredth is 13.96

The box plots show the data distributions for the number of customers who used a coupon each hour during a two-day sale.
Which measure of variability can be compared using the box plots?
interquartile range
standard deviation
mean
median
Answers
Answer:
Interquartile age
Step-by-step explanation:
The box plots that is being referred to are missing, however, we can still answer this without the box plots.
The appropriate measure of variability that can be easily determined by a box plot is the interquartile range. Which is the difference between the 3rd quartile and the 1st quartile.
On a box plot, the first quartile is the data value ta the beginning of the edge of the rectangular box while the third quartile is at the end of the edge of the rectangle box. So, this makes is easy for use interquartile range as a measure of variability when comparing both.
Answer:
Interquartile range (IQR)
explanation:
Mean and median are both measures of center so it can't be those two, and the standard deviation is a measure of variability but only when the graph, box plot or any other type of graph is symmetric

To solve the equation 34x=15, Abby multiplied both sides by ¾ and got a solution of x=1114. Explain the error that Abby made and then find the correct value of x.
Answers
Answer:
x = 20
Step-by-step explanation:
3/4x = 15
Abby's calculation:
3/4x = 15
Multiply both sides by 3/4
x = 1114
Abby's error was multiplying both sides by 3/4 instead of dividing both sides by 3/4 to get the value of x
Correct calculation:
3/4x = 15
Divide both sides by 3/4
3/4x ÷ 3/4 = 15 ÷ 3/4
x = 15 × 4/3
x = 60/3
x = 20
Check:
3/4x = 15
3/4*20
= (3*20) / 4
= 60/4
= 15
3/4*20 = 15

Answer:
h = 3 cm
Step-by-step explanation:
The volume (V) of a rectangular prism is calculated as
V = Ah ( A is the area of the base and h the height )
Here V = 36 and A = 6 × 2 = 12 cm² , then
12h = 36 ( divide both sides by 12 )
h = 3
Answer: 3 cm
Step-by-step explanation:
The formula to solve the volume of a rectangular prism is V = l x w x h
Where V is volume, l is length, w is width, and h is height
Givens are, Volume = 36 cm3
length = 6 cm
width = 2 cm
Now, we will plug in the numbers to the formula
36 cm3 = 6cm x 2cm x h
36 cm3 = 12 cm2 x h
divide 12cm2 on both sides
36cm3/12cm3 = h
h = 3cm
