Answer 1

Answers:

a)  x+y = 70b) The graph is shown below. The lines intersect at (20, 50) meaning that she has 20 quarters and 50 dimes.

========================================================

Explanation:

a)

x = number of quarters

y = number of dimes

x+y = number of dimes and quarters

x+y = 70 coins total

-----------

b)

Use a graphing tool like Desmos or Geogebra to plot each linear equation on the same xy grid. I'm using Geogebra to get what is shown below.

The red line 25x+10y = 1000 goes through (0,100) and (40,0)

The blue line x+y = 70 goes through (0,70) and (70,0)

The two lines intersect at (x,y) = (20,50)

This means x = 20 and y = 50 pair up together.

Kateri has 20 quarters and 50 dimes

20 quarters = 20*25 = 500 cents = 500/100 = $550 dimes = 50*10 = 500 cents = 500/100 = $5

Total value = $5 + $5 = $10

Also note that 20 quarters + 50 dimes = 70 coins total

Both conditions have been confirmed.

An apartment complex is turning the grassy area next to the current parking lot into more parking space.Once they are done,how much total parking area will there be?

Answers

Once the apartment complex have been turned to a parking area, the total parking area will be 1620 square units

How to determine the total parking area?

From the complete question, the parking area consists of the following shapes and dimensions

Rectangle: 28 units by 40 unitsRectangle: 20 units by 25 units

The area of a rectangle is the product of its dimensions.

So, the area of the parking area is:

Area = 28x40 + 20x25

Evaluate the products

Area = 1120 + 500

Evaluate the sum

Area = 1620

Hence, the total area of the parking area is 1620 square units

Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm with angle measures of 55°, 60°, and 65°. Which of the following is a possible way to classify the triangle by side and angle measurements?
A. Obtuse and isosceles
B. Acute and scalene
C. Obtuse and equilateral
D. Acute and equilateral

Answers

Answer:

Acute and Scalene

Step-by-step explanation:

The measurments of the triangle are all almost equal and all the angles are less than 90 degrees, so all of them are acute angles. The scalene triangle has almost all equal sides.

The possible way to classify the triangle by side and angle measurements is,

⇒ Acute and scalene.

What is mean by Angle?

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm with angle measures of 55°, 60°, and 65°.

Since, All the angles are less than 90 degree.

Hence, It shows the Acute angle.

Here, Terrance draws a triangle with sides of 10 cm, 11 cm, and 12 cm.

Clearly, All the sides of triangle are not same in length.

Thus, It shows scalene.

Thus, The possible way to classify the triangle by side and angle measurements is,

find the area of the shaded region. Use the formula A= pie r^2 to find the area of a circle

Answers

Answer:

(π6x+21π)m²

Step-by-step explanation:

Solution,

For small circle

radius(r)=x+2

Area(A1)=πr²

Area(A1)=π×(x+2)²

Area(A1)=π×(x²+4x+4)

Area(A1)=πx²+π4x+4π

For big circle

radius(r)=x+5

Area(A2)=πr²

Area(A2)=π×(x+5)²

Area(A2)=π×(x²+10x+25)

Area(A2)=πx²+π10x+25π

Again,

Area of shaded part=A2-A1

Area of shaded part=πx²+π10x+25π-(πx²+π4x+4π)

Area of shaded part=πx²+π10x+25π-πx²-π4x-4π

Area of shaded part=π6x+21π

For pattern Q we start at 6, and then we subtract 2 and multiply by 2 to get the next element.

[tex]b_1 = 6\\\\b_2 = (6 - 2)*2 = 8\\\\b_3 = (8 - 2)*2 = 12\\\\b_4 = (12 - 2)*2 = 20\\\\b_5 = (20 - 2)*2 = 36\\\\[/tex]

Answers

The solution of the equation is approximately x = 4 and there are no other solutions

How to determine the solution of the equation?

The equation is given as

0.1(2^x) = 4/x

Also, we have the table of values as one of the given parameters

Next, we check the table of values

From the table of values, we can see that:

The value of x is between x = 3 and x = 4

This is so because the values of the expressions 0.1(2^x) and 4/x are closest at these values

However, the value of x is closer to 4 than 3

This means that

x = 4 (approximately)

Hence, the solution of the equation is approximately x = 4 and there are no other solutions

The order of operation (PEMDAS) states that:

P - ParenthesisE - ExponentsM - MultiplicationD - DivisionA - AdditionS - Subtraction

Given expression:

[{(-6) + 7 - 3} x 2] ÷ 4

We can see that "-6" is the integer that is inside the parenthesis "( )". Therefore, we can open the parenthesis "( )".

⇒ [{-6 + 7 - 3} x 2] ÷ 4

Simplify the expression inside the curvy brackets "{ }" using PEMDAS.

⇒ [{1 - 3} x 2] ÷ 4                     [PEMDAS]⇒ [{-2} x 2] ÷ 4                         [PEMDAS]

Now we can open the curvy brackets "{ }".

Finally, open the long brackets "[ ]" and simplify the expression obtained.
