Answer:
the side is halved the area of the square will be one fourth
Step-by-step explanation:
example : 6cm
area : 6x6 = 36
now half of 6 is 3
so : 3x3 = 9
one-fourth of 36 is 9

Reorder the steps to construct Angle JOB, a copy of Angle A.
__ Construct oj
__ Place your compass point at the vertex of Angle A. Create an arc that intersects both rays of Angle A.
__ On Angle A, set your compass point on the intersection of the arc and ray and the pencil on the other intersection of the arc and second ray. Lock your compass.
__ Place the point of the compass on the intersection of the arc on OB. Mark an arc through the large arc created in a previous step. Label the point of intersection of the two arcs point J.
__ Draw a ray that will become one of the two rays of the new angle. Label the ray OB.
__ Without changing your compass setting, create an arc from point O that intersects OB. Be sure to make a large arc.
Answer:
The right order is given as follows;
_Draw a ray that will become one of the two rays of the new angle, label OB
_Place your compass point at the vertex of Angle A. Create an arc that intersects both rays of Angle A
_On Angle A, set the compass point on the intersection of the arc and ray and the pencil on the other intersection of the arc and second ray. Lock your compass
_Without changing your compass setting, create an arc from point O that intersects OB. Be sure to make a large arc.
_Place the point of the compass on the intersection of the arc on OB. Mark an arc arc through the large arc created in a previous step. Label the point of intersection of the two arcs point J.
_Construct OJ
Step-by-step explanation:
1) The first step is to draw a line in the location where the angle to be copied is to be constructed
2) The distance of two points on the rays forming the angle to be copied from the vertex are found by drawing an arc from the vertex and setting the compass opening width to the distances between the intersection of the arc and the rays
3) With the set compass width from the step above, an arc is drawn which intersects the constructed first new ray. The arc is made to extend to a large angle to accommodate large angle sizes
4) From the point of intersection of the arc on the new line, another arc is drawn to intersect the previous arc located on the new line construction
5) Join the point intersection of the two arcs on the new construction to the start point of the constructed first new line (the point from which the first arc was constructed to complete the construction of a copy of the angle.

Answer:
88%
Step-by-step explanation:
22/25 = .88 x 100= 88%
Answer:
88%
Step-by-step explanation:
First, you start with the bottom (denominator). You turn it into 100 since all percentages are over 100. So 25 times 4 is 100. Therefore, you also have to multiply the top with a 4, getting an 88 over 100. That is equal to 88%.

Now determine the factors of the third term

We need the factors that will add up to the middle term

Place these factors as the second term in each of the parenthesis.
(

(

(x-5)(x-9) is the factored form of the expression x²-14x+45
The given expression is x²-14x+45
x is the variable in the expression
x square minus forteen times of x plus forty five
Plus and minus are operators in the expression
x²-9x-5x+45
Now let factor out the expression
x(x-9)-5(x-9)
(x-5)(x-9)
Hence, the factored form of the expression is (x-5)(x-9)

A thief steals an ATM card and must randomly guess the correct three-digit pin code from a 7-key keypad. Repetition of digits is allowed. What is the probability of a correct guess on the first try? The number of possible code is__?? (Type an integer or fraction. Simplify your answer) The probability that the correct code is given in the first try is __?? (Type an integer or fraction. Simplify your answer.)
Answer:
1/343
Step-by-step explanation:
Given that:
Required pass code = 3 digit long
Digit or keypad option / length = 7
What is the probability of a correct guess on the first try? To obtain this,
Probability = required outcome / Total possible outcomes
The required outcome = correct guess; which is a single combination of the right digits = 1
Total possible outcomes = number of available combinations or the number of possible codes = (7^3) = 343
Hence,
P(right guess on first try) = required outcome / Total possible outcomes
= 1/343

Answer: 71, 175, 180
Step-by-step explanation:
Find the interquartile range. 127- 112 = 23 Multiply by 1.5 = 34.5
Add to the mean 114 + 34.5 = 148.5
Subtract from the mean 114 - 34.5 = 79.5
Any number greater than 148.5 or less than 79.5 is considered an outlier

The football team scored 128 total points last season. This year they scored 144 total points. What is the percent of change?
Answer:
88%.
Step-by-step explanation:
Answer:
12.5% increase
Step-by-step explanation:
Take the difference in points
144-128 = 16
And divide by the original number of points
16/128 =.125
Change to percent form
12.5%
Since the points went up it is an increase
12.5% increase
