Keiko estimated that it would take her 18 hours to build a shed for her 12.5 backyard. It only took her hours. What is the percent error of her estimate relative to the time it actually took?
Answers
The percent error of her estimate relative to the time it actually took is approximately 5.9%
What is the percent error?Estimated time to construct the shed = 18 hoursActual time taken to build the shed = 17 hoursError = Estimated time to construct the shed - Actual time taken to build the shed
= 18 hours - 17 hours
= 1 hour
Percent error = error / actual time × 100
= 1/17 × 100
= 0.058823529411764 × 100
= 5.882352941176470
Approximately,
5.9%
Consequently, the percent error of Keiko estimation and actual time is 5.9%

Answer:
10.5 cm
Step-by-step explanation:
YZ corresponds to TU
YZ:TU = 9:3 = 3:1
XY corresponds to ST
ST = 3.5 cm
XY:ST = 3:1
XY/ST = 3/1
XY/3.5 cm = 3
XY = 10.5 cm
Step by step
Line up your known sides
TU and ZY are similar
The dilation rate is small to large x3 ratio
(9/3) therefore
ST to TY is also rate of x3
ST = 3.5 x 3 = 10.5cm

Answers
From the solution to the given inequality, the correction representations are -6x + 15 < 10 - 5x and a number line from -3 to 7, with an open circle at 5 and an arrow pointing to the right.
Solving Linear InequalitiesFrom the question, we are to determine the correct representations of the given inequality
The given inequality is
-3(2x - 5) < 5(2 - x)
To determine the correct representation, we will solve the inequality
Solving the inequality
-3(2x - 5) < 5(2 - x)
Clear the parentheses by applying the distributive property
-6x + 15 < 10 - 5x
Add 6x to both sides
-6x + 6x + 15 < 10 - 5x + 6x
15 < 10 + x
Subtract 10 from both sides
15 - 10 < 10 - 10 + x
5 < x
Therefore,
x > 5
Hence, the correction representations are -6x + 15 < 10 - 5x and the number for x > 5

Answers
Applying the properties of a parallelogram:
1. Length of AC = 24.8 units
2. x = 1
What are the Properties of a Parallelogram?Some properties of parallelogram we need to recall in order to solve the problem given are:
They have two pair of sides that are parallel to each other and also of the same length.They have two diagonals that bisect each other into equal halves.1. q = 1x + 10
AC = 7x + 8
Therefore:
q = 1/2(AC) [based on the property of a parallelogram]
Substitute
x + 10 = 1/2(7x + 8)
Solve for x
2(x + 10) = 7x + 8
2x + 20 = 7x + 8
2x - 7x = -20 + 8
-5x = -12
x = -12/-5
x = 2.4
Length of AC = 7x + 8 = 7(2.4) + 8
Length of AC = 24.8 units
2. x + 8 = 7x + 2 [based on the property of a parallelogram]
x - 7x = -8 + 2
-6x = -6
-6x/-6 = -6/-6

An algebraic expression is one that has several operations between numbers and letters (unknowns): addition, multiplication, subtraction, division, potentiation, rooting, etc.
LET'S GO TO THE SOLUTION:
Let x be the initial value of the car, we know that it depreciates 10% when leaving the agency and another 5% after one year. If the value of this car is $51,300.00 after 1 year, we will have to:
When you leave the agency, your value decreases by 10%:

Two angles in triangle PQR are congruent, ∠P and ∠Q; ∠R measures 22.75°. What is the measure of ∠P?
22.75°
78.625°
134.5°
157.25°
Answers
Answer:
<P = 78.625°
Step-by-step explanation:
All of the angles in a triangle add up to 180.
<R + <Q + <P = 180
We can use x for <P and <Q, as they represent the same value because they are congruent.
<R + x + x = 180
Now, we want to substitute known values in and work backwards to find out what angle <P and <Q are.
2x + <R = 180
Put 22.75 in for <R.
2x + 22.75 = 180
Subtract on both sides.
2x = 157.25
Divide 2 on both sides to isolate x
x = 78.625
Since x represents <P and <Q, that means they are both 78.625 degrees each.
<P = 78.625

A half circle is joined to an equilateral triangle with side lengths of 12 units.Select all the expressions that correctly calculate the perimeter of the shape.
Answers
The perimeter of the figure described in the question is 42.84cm
How to get the perimeter of the figure?The figure is defined by a half circle is joined to an equilateral triangle with side lengths of 12 units.
So the perimeter of the figure will be equal to half of the circumference of the triangle plus the length of the two exposed sides of the triangle.
The diameter of the circle will also be 12 units, remember that the circumference of a circle of diameter D is:
C = 3.14*D
In this case, the circumference of half circle is:
C = 3.14*D/2
Replacing the value of the diameter:
C = 3.14*12cm/2 = 18.84cm
Adding the two sides of the triangle we get the perimeter.
P = 18.84cm + 2*12cm = 42.84cm

n Game 1, Emerson struck out 30 times in 90 times at bat. In Game 2, he struck out 40 times in 120 times at bat. In Game 3, Emerson struck out 42 times in 140 times at bat.
Answers
The percentage of time that Emerson actually hit the ball is given by the following option:
C. 68%.
How to calculate a percentage?A percentage is calculated applying proportions, as it is a fraction of the total amount, obtained as the division of the number of desired outcomes by the number of total outcomes and multiplied by 100%.
Hence the outcomes in this problem are given as follows:
Desired: outcomes that he did not struck out.Total: all the at bats.Then the number of desired outcomes is obtained as follows:
(90 - 30) + (120 - 40) + (140 - 42) = 238.
The number of total outcomes is obtained as follows:
90 + 120 + 140 = 350.
Then the percentage is given as follows:
P = 238/350 x 100% = 68%.
Meaning that the correct option is given by option C.
