Answer:

1.2 sq in.

Step-by-step explanation:

We know the formula to find the area of a trapezoid is a+b/2(h)

4+8/2(5)=12/10

12/10=1.2

Therefore the area is 1.2 sq in.

Answer:

The water level will change at a rate of - 2 7/18 inches per year

Step-by-step explanation:

From the question, we have a change of -7 1/6 inch every 3 years

We now want to calculate the value of the change every year

Mathematically, that will be;

- 7 1/6 divided by 3

= -43/6 divided by 3

= -43/18 = - 2 7/18 inch per year

Step-by-step explanation:

Given:

Price of a pair of binoculars = $155.75

Sales tax = 6.5%

To find:

The amount of sales tax Nick will pay on the purchase to the nearest cent.

Solution:

According to the question,

Sales Tax value = 6.5% of Price of a pair of binoculars

                        [tex]=\dfrac{6.5}{100}\times 155.75[/tex]

                        [tex]=0.065\times 155.75[/tex]

                        [tex]=10.12375[/tex]

                        [tex]\approx 10.12[/tex]

Therefore, the amount of sales tax is $10.12.

Step-by-step explanation:

Answer:

7 meters per second.

Step-by-step explanation:

Given that,

Andy runs 436.8 meters in 62.08 seconds.

We need to find how far he run in each second. It can be calculated by dividing distance by time taken as follows :

[tex]x=\dfrac{436.8\ m}{62.08\ s}\\\\=7.03\ m/s[/tex]

or

x = 7 m/s

So, Andy will cover 7 meters per second.

Numerator = 3

Step-by-step explanation:

Let the numerator is x.

The denominator is 6 more that the numerator, 6+x

The fraction is equivalent to 1/3. ATQ,

[tex]\dfrac{x}{x+6}=\dfrac{1}{3}[/tex]

Cross multiplying both sides,

[tex]3x=x+6\\\\3x-x=6\\\\2x=6\\\\x=\dfrac{6}{2}\\\\x=3[/tex]

Numerator = 3

So, the numerator is 3.

Answer:

Step-by-step explanation:

Because every triangle that can ever be made has three sides, you can open up the triangle so that it becomes a straight horizontal line. A horizontal line is also 180 degrees which is why this idea works with triangles.

The reason for the sum of the angles in any triangle is 180 is that when we open up the sides of a triangle we get a straight line where the angle of a straight line is 180 degrees.

It is a two-dimensional figure which has three sides and the sum of the three angles has are equal to 180 degrees.

We have,

The sum of the angle measures in any triangle is 180.

We see that,

In a triangle, there are three sides and three angles.

If we open up the triangle, we see that the three sides of the triangle form a straight line.

The angle of a straight line is 180 degrees.

Thus,

The reason for the sum of the angles in any triangle is 180 is that when we open up the sides of a triangle we get a straight line where the angle of a straight line is 180 degrees.

Answer:

Step-by-step explanation:

The sum of length and width is half the perimeter. If the perimeter is the same, so will be the sum of length and width:

  7 + 5 = x + (4x -3)

  15 = 5x . . . . . . . add 3, simplify

  3 = x

The value of x is 3.

Answer:

1/2 + 9(p)

Step-by-step explanation:

Answer:

[tex]\frac{1}{2}[/tex] + 9p

Step-by-step explanation:

add one-half can translate to +[tex]\frac{1}{2}[/tex], so we know that this needs to be in the expression somewhere

the "to" means that the sentences is going to state the next term in the expression

9 times p means 9 multiplied by p, and this can be written as 9p

so put our terms together to get [tex]\frac{1}{2}[/tex] + 9p

Answer:

f(- 1) = - 19

Step-by-step explanation:

To evaluate f(- 1) substitute x = - 1 into f(x) , that is

f(- 1) = - 4(- 1)² + 13(- 1) - 2 = - 4(1) - 13 - 2 = - 4 - 13 - 2 = - 19

Answer:

Step-by-step explanation:

Given the equation 1 – (2x + 4) = –4x + 5, we are to find the correct solution of the equation;

Step 1: Open the parenthesis;

1 – (2x + 4) = –4x + 5

1-2x-4 = -4x + 5

1-4-2x = -4x +5

-3-2x = -4x + 5

Step 2: Collect like terms

-2x + 4x = 5 + 3

2x = 8

Step 3: divide both sides by 2;

2x/2 = 8/2

x = 4

Hence the correct value of x is 4
