Val needs to find the area enclosed by the figure. The figure is made by attaching
semicircles to each side of a 46-m-by-46-m square. Val says the area is 1,206.12
m². Find the area enclosed by the figure. Use 3.14 for 1. What error might Val have
made?
Answer: See below
Step-by-step explanation:
Radius of the semicircle = 46/2 = 23 m
[tex]\therefore$ Area enclosed by the figure $=4 \times$ Area of semicircles + Area of square \begin{aligned} \\&=4 \times 3.14 \times(23)^{2} \times \frac{1}{2}+(46)^{2} \\&=3322.12+2116 \end{aligned} \\\\\\Area enclosed $=5438.12 \mathrm{~m}^{2}$[/tex]
So, Val might have have subtracted 2116 from 3322.12 instead of adding since 3322.12 - 2116 = 1206.12
Mato is making a leather belt inlaid with beads. On the first day there were b beads on the belt. On
the fourth day, there were b³ beads on the same belt. There were 216 beads on the belt on the
fourth day.
How many beads were on the belt on the first day?
Answer:
6
Step-by-step explanation:
On the fourth day, there were b^3 beads and 216 beads on the belt, which means b^3 = 216. Taking the cube root of both sides, we have b = 6, which means there were 6 beads on the belt on the first day.

what is 10066×140 please help me and explain the answer
Your answer would be 1,409,240
you would mutpliy 0 and 9 first and keep mutpliying until you get your answer
Answer:
The answer is 1,409,240
Step-by-step explanation:
I asume you are doing this by hand so here are the steps:
1. set up the problem- whitch would look like this
10066
x 140
Now you have to mutiply the 1s place, by all the number places of the top number
Sence you have a zero in the 1s place you can just put a x, whitch would look like:
10066
x 140
x
Now you do that for all the places
2 2 * Make sure you rase the number to the next place
10066 4*6 = 24 24+4= 28 4*0=0
x 140
40284x
Now that you mutiplyed the 4 by everything and got the answer of 402840 (the x is just a zero) then you leave it aside and mutiply the 1s by everything whitch is much simpler.
10066 1*6= 6 1*0= 0 1*1 =1
x 140
10066xx (now you put 2 X's)
You get the answer of 1006600 and you add it with 402840
whitch is 1,409,240 (and that is your answer)
Match each expression on the left with its corresponding simplified form.
A) m + 5
B) m + 3
C) m + 4
D) m + 8
note: there is no single answer. every single answer has to get matched
The equivalent expressions are: (4 + m) + 1 = m + 5, (m + 3) + 1 = m + 4, (2 + m) + 6 = 2 + m + 6 and (1 + m) + 2 = m + 3
What are equivalent expressions?Equivalent expressions are expressions that have equal values when evaluated
Start by evaluating each expression.
(4 + m) + 1
Remove the bracket
(4 + m) + 1 = 4 + m + 1
Evaluate
(4 + m) + 1 = m + 5
(m + 3) + 1
Remove the bracket
(m + 3) + 1 = m + 3 + 1
Evaluate
(m + 3) + 1 = m + 4
(2 + m) + 6
Remove the bracket
(2 + m) + 6 = 2 + m + 6
Evaluate
(2 + m) + 6 = m + 8
(1 + m) + 2
Remove the bracket
(1 + m) + 2 = 1 + m + 2
Evaluate
(1 + m) + 2 = m + 3
Hence, the equivalent expressions are: (4 + m) + 1 = m + 5, (m + 3) + 1 = m + 4, (2 + m) + 6 = 2 + m + 6 and (1 + m) + 2 = m + 3

Answer:
~Shoto todoroki here~
I think this would be your solved equation, -3x+5 making your X intercepts at: (5/3, 0) and your Y intercepts at: (0, 5)
The equation has Unique Solution.
What is solution of equation?The solution to a linear equation is the point at which the lines that represent the intersection of two linear equations are defined. In other words, the solution set for the system of linear equations is the set of all possible values for the variables that satisfy the given linear equation.
There are three ways to solve the set of linear equations.
Unique Solution, No Solution and Infinitely Many Solutions.
Given y = 1/2x - 2
x 0 4
y -2 0
y = -3x + 5
x 0 2
y 5 -1
the graph is attached
solving by substitution
y = 1/2x - 2
y = -3x + 5
both equations are equal for y
1/2x -2 = -3x + 5
1/2x + 3x = 5 + 2
7/2x = 7
x = 2
and at x =2 y = -1
equation intersect at (2, -1) and have unique solution.
Hence there is Unique Solution for equations.

Answer:
The Answer is C
Step-by-step explanation:
Anna draws a angle that intercets at 1
When two straight lines or rays intersect at a shared endpoint, an angle is generated. The exact number of points at which the two rays will intersect is 1. The correct option is C.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
As per the definition of an angle, the point at which the two of the given rays will intersect each other is exactly 1 point.
Hence, the exact number of points at which the two rays will intersect is 1.

Which equation represents a line that is perpendicular to the line passing through (-8,7) and (2,4)?
Explanation:
Step 1) Because this is already solved for y we can get the slope of the perpendicular line by taking the slope of the given line (-3) and "flipping" it and reversing the sign:
−3 becomes −−13→+13→13
Therefore the slope of the perpendicular line is 13
Step 2) Use the point slope for to find the perpendicular equation:
y−1=13(x−−1)
y−1=13(x+1)
y−1=13x+13
y−1+1=13x+13+1
y−0=13x+13+33
y=13x+43
y=(13)x+(43)

A. The minimum of set B is smaller than the minimum of set A
B. The maximum of set A is the same as the maximum of set B
OC. The median of set A is larger than the median of set B
OD. The mean of set A is larger than the mean of set B
The correct option is D the mean of set A is larger than the mean of set B.
A box and whisker plot—also called a box plot—displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum. A vertical line goes through the box at the median. The whiskers go from each quartile to the minimum or maximum.
Here in the the box and whisker plot data values are not marked and these based on five points so mean cannot be determined here because mean required marked values.
The mean formula is given as the average of all the observations. It is expressed as Mean = {Sum of Observation} ÷ {Total numbers of Observations}.
But here in box and whisker plot no actual values are known so we can't find the mean.
Hence mean cannot be determined here with that given data.
