Applying the properties of a parallelogram:

1. Length of AC = 24.8 units

2. x = 1

Some properties of parallelogram we need to recall in  order to solve the problem given are:

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

x = 1

Answer:

(4, 0)

Step-by-step explanation:

7x - 10y = 28

7x - 3y = 28

------------------

(7x - 10y = 28) × -1

-7x + 10y = -28

--------------------------

-7x + 10y = -28

7x - 3y = 28

--------------------------

           7y = 0

             y = 0

7x - 10y = 28

7x - 10(0) = 28

7x = 28

Answer:

B

Step-by-step explanation:

A is a reflection across the y-axis.

B is the result of a rotation around the origin either by 90° counterclockwise, or by 270° clockwise.

C is a reflection across the x-axis.

D is a translation (shift) by -5 to the left.

The value of the car zero km is given by the expression x = 60000.

LET ME EXPLAIN SOMETHING:

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%:

After a year, its value decreases by 5%:

0.855x = 51300

x = 60000

Answer:

d) 189.3 in²

Step-by-step explanation:

Area of rectangle is,

→ w × l

→ 10 × 15

→ 150 in²

Area of semi circle is,

→ (1/2)πr²

→ (1/2) × 3.14 × (5)²

→ 1.57 × 25

→ 39.3 in²

Now the total area will be,

→ 150 + 39

→ 189.3 in²

Thus, total area is 189.3 in².

The coordinates of the points are given as follows:

Answer:

Option: A is the correct answer.

Step-by-step explanation:

Clearly from the graph we could observe that the graph is a decay exponential function as the graph of the function is decreasing with the increasing value of x.

Hence, the rate has to be less than 1.

So, option: B and D are ruled out as they represent a growth exponential function.

Also from the graph given in the question we could observe that when x=0 the value of y is:

The percent error of her estimate relative to the time it actually took is approximately 5.9%

Error = 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

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

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.

From 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

The percentage of time that Emerson actually hit the ball is given by the following option:

C. 68%.

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:

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.

The problem is:

In 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. What percentage of times at bat did Emerson actually hit the ball? a. 39% b. 85% c. 68% d. 45%​

The perimeter of the figure described in the question is 42.84cm

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
