If m∠EBD = 36° and m∠DBC = 108° find m∠EBC

Answers

Check the picture below.

The measure of m∠EBC if m∠EBD = 36° and m∠DBC = 108° is 144degrees

The point where two lines intersect is known as the angle.

From the diagram shown:

m∠EBC = m∠EBD + m∠DBC

Given the following:

m∠EBD = 36degrees

m∠DBC = 108degrees

Substitute the given values into the expression as shown:

m∠EBC = 36 + 108

m∠EBC = 144degrees

Hence the measure of m∠EBC is 144degrees

How many solutions for x does the following equation have?
3(X + 8) - 1 = 3x + 4
A. 4
B. O
c.1
D. infinite

Answers

Answer:

B. No solutions.

Step-by-step explanation:

Let's try solving it:

3(x + 8) = 3x + 4

3x + 8 = 3x + 4.

There are no solutions  because if we simplify we get an absurd result. Subtract 3x from both sides of the equation:

3x - 3x + 8 = 3x - 3x + 4

8 = 4.

Final answer:

There are no solutions for x in this equation.

Explanation:

To solve this equation, we need to combine like terms and isolate the variable. Here are the steps:

Expand the brackets: 3(x + 8) - 1 = 3x + 4 becomes 3x + 24 - 1 = 3x + 4.Combine like terms: 3x + 24 - 1 = 3x + 4 becomes 3x + 23 = 3x + 4.Isolate the variable: Subtract 3x from both sides to get 23 = 4.

Since 23 does not equal 4, these two sides are not equal. Therefore, there are no solutions for x in this equation.

Rob purchased a rug for his apartment the rug is 72 inches by 96 inches . Calculate the area of the rug in square inches

Answers

Answer:

Area of the rug will be 6912 square inches.

Step-by-step explanation:

Rob has purchased a rug having measurement 72 inches by 98 inches for his apartment.

Since the rug will be in the shape of a rectangle, area will be represented by the formula,

Area = Length × width

        = 72 × 96

        = 6912 square inches.

Therefore, area of the rug will be 6912 square inches.

To calculate the area of Rob's rug, multiply the length of 96 inches by the width of 72 inches, resulting in an area of 6,912 square inches. Thus, the area of the rug is 6,912 square inches.

To find the area of Rob's rug, you need to multiply the length and the width of the rug.

Length = 96 inchesWidth = 72 inches

The formula for area is:

Area = Length × Width

Using the given dimensions:

Area = 96 inches × 72 inches = 6,912 square inches

Therefore, the area of the rug is 6,912 square inches.

James wants to carpet the room shown in the diagram. If he uses 12 ft wide carpet strips, how many linear feet will he need to buy?

A) 11

B) 12

C) 20

D) 60

Answers

The area of the room = (40 x 24) - (20 x 12)

Area = 960 - 240 = 720 square feet

Divide square feet by width of a strip:

720 / 12 = 60 linear feet.

The answer is D.

Answer : The correct option is, (D) 60

Step-by-step explanation :

First we have to calculate the area of room.

Area of room = Area of big rectangle + Area of small rectangle

Area of rectangle = Length × Width

Area of room = (40 × 12) + (20 × 12)

Area of room = 720 square feet

Now we have to calculate the number of linear feet will he need to buy.

Number of linear feet = [tex]\frac{\text{Area of room}}{\text{Width of carpet strips}}[/tex]

Number of linear feet = [tex]\frac{720}{12}=60[/tex]

Thus, the number of linear feet will he need to buy is, 60

Gabby’s goal is to save more than $400. She saves $20 per week plus $50 initially. Let we b the number of week.

1. Write an inequality that represents this situation.
2. What is the least number of weeks she must have?

Answers

Answer: 17

Step-by-step explanation:

Final answer:

Gabby's savings over 'b' weeks can be written as an inequality 50 + 20b > 400. Simplifying this, we find that Gabby has to save up for at least 18 weeks to save more than $400.

Explanation:

Gabby's savings can be represented as 50 + 20b, with 'b' being the number of weeks. For her to save more than $400, we can write this inequality 50 + 20b > 400. Subtract 50 from both sides to simplify the inequality and we get 20b > 350. To find the least number of weeks, divide both sides by 20 to solve for b and we get b > 17.5. However, since 'b' must be a whole number (because you can't have half a week), the least number of weeks Gabby must save is 18 weeks.

Answers

Final answer:

Paulo's time in standard notation is 15,600 seconds. Miguel ran the marathon in a shorter time of 15,360 seconds. For the given equations, A) and B) each have one solution (x=3 and x=10, respectively), while C) has an infinite number of solutions.

Explanation:

To convert Paulo's time from scientific to standard notation, we multiply 1.56 by 10 to the power of 4. This equals 15,600 seconds. Next, we need to convert Miguel's time to seconds to directly compare the two durations. Miguel ran for 4 hours and 16 minutes, which is equal to (4 × 3600) + (16 × 60) = 14,400 + 960 = 15,360 seconds. Therefore, Miguel ran the race in a shorter amount of time by 240 seconds.

For question 2, we solve the following equations:

For equation A) 2x + 4(x - 1) = 2 + 4x, after simplifying we get 2x + 4x - 4 = 2 + 4x. The 4x terms cancel out and we are left with 2x - 4 = 2. Solving for x gives x = 3. This equation has one solution.

For equation B) 25 - x = 15 - (3x + 10), simplifying gives 25 - x = 5 - 3x. Solving for x yields x = 10, so this equation also has one solution.

For equation C) 4x = 2x + 2x + 5(x - x), simplifying results in 4x = 4x, which is true for all values of x. Therefore, this equation has an infinite number of solutions.

The mean (or average) of a set of numbers can be found with the following formula:

[tex]Mean = \frac{A_{1} + A_{2} + ... + A_{N}}{N}[/tex]

For this problem, we have five numbers, so we add them together and divide by 5:

[tex]Mean = \frac{440}{5}[/tex]

[tex]Mean = 88[/tex]

88%

Step-by-step explanation:

Emma took tests of her 5 chapters throughout the year.

She received  the score on the five tests

92%, 85%, 78%, 97% and 88%

We have to calculate the average (mean) of her final grade.

average =  [tex]\frac{\text{addition of all grades}}{\text{total number of tests}}[/tex]

=  [tex]\frac{92+85+78+97+88}{5}[/tex]

A nurse mixes 60cc of a 50% saline solution with a 30% saline solution to produce a 35% saline solution. How much of the 30% solution should he use?

Answers

Final answer:

To create a 35% saline solution by mixing a 50% and a 30% solution, the nurse needs to use 6000cc of the 30% solution.

Explanation:

The question asks how much of a 30% saline solution a nurse needs to mix with 60cc of a 50% saline solution to achieve a final solution concentration of 35%. To solve this problem, let's denote the volume of the 30% solution needed as x cc. Using the concept of weighted averages for concentrations, we can set up the following equation:

(60cc × 50%) + (x cc × 30%) = (60cc + x cc) × 35%

Solving this equation, we get:

3000 + 0.3x = 0.35(60 + x)

3000 + 0.3x = 21 + 0.35x

Subtracting 0.3x from both sides:

3000 = 21 + 0.05x

Subtracting 21 from both sides and dividing by 0.05:

x = 6000 cc

Therefore, the nurse should use 6000cc of the 30% saline solution to achieve the desired concentration.
