Answer:

∠a = 133°∠b = 15°∠c = 75°∠d = 58°

Step-by-step explanation:

We don't know the definitions, properties, postulates, or theorems on your list, so we'll use the following:

a right angle measures 90°a straight angle measures 180°the acute angles in a right triangle total 90°an exterior angle of a triangle is equal to the sum of the remote interior anglesthe measure of an angle is equal to the sum of the measures of its parts.

∠a = 180° -47° = 133°; reasons 2, 5. The angles form a straight angle.

∠b = 47° -32° = 15°; reason 4

∠c = 90° - ∠b = 90° -15° = 75°; reason 3

∠d = 90° -32° = 58°; reasons 1, 5. The angles form a right angle. If you want to get picky, we know it is a right angle by reasons 1 and 2. The marked right angle and the sum of 32° and ∠d together form a straight angle.

Eric is hiring a company to install carpeting in his house. The company charges a one-time installation fee plus a certain amount per square yard of carpeting. The graph below shows the relationship between the number of square yards of carpeting and the total cost, in dollars.
A. Slope of the graph
B. Y-intercept of the graph
C. Domain of the function
D. Range of the function

Answers

Answer:

As axjames said, it is A. Slope of the graph.

Step-by-step explanation:

A slope in a graph can mean a increase or a decrease in whatever. For example a decrease in miles per hour (mph), business sales, and more. Also don't forget slopes with decrease are negative slopes and slopes with increase are positive slopes. A positive slope moves upward on a graph from left to right. A negative slope moves downward on a graph from left to right. It's important to note that we work from left to right when dealing with slope.

The graph of a linear equation is a straight line.

The quantity that represents the cost per square yard of carpeting is the (a) slope of the graph.

The slope of the graph is the rate of change of the total cost over the change in square yard.

This means that:

The slope of the graph is the cost per square yard of the carpet.

Hence, the required quantity is (a)

\{ - 2 - (2 \times - 12) \}{−2−(2×−12)}

\{ - 2 - ( - 24)\}{−2−(−24)}

\{ - 2 + 24 \}{−2+24}

the required value is 22

The simplified value of (a−2b)³ is 10648.

What is equation?

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign.

Parts of an Equation

There are different parts of an equation which include coefficients, variables, operators, constants, terms, expressions, and an equal to sign. When we write an equation, it is mandatory to have an "=" sign, and terms on both sides. Both sides should be equal to each other. An equation doesn't need to have multiple terms on either of the sides, having variables, and operators.

given:

(a−2b)³

and, a=−2 and b=−12

Now, substituting the values

(a−2b)³

= ((-2)−2(-12))³

= (-2 + 24)³

= 22³

= 10648

Hence, the simplified value is 10648.

Hence,Option C is correct..

The solution is: Option C is correct. Factor using the GCF: 49x - 7 is

7(7x-1).

Here, we have,

given that,

we have to factor using the GCF: 49x - 7.

we know that,

In mathematics, the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For two integers x, y, the greatest common divisor of x and y is denoted {\displaystyle \gcd}.

so, we have,

49x - 7

now, we know,

7 * 7 = 49

and, 7 * 1 = 7

so, we get, the GCF of 49 and 7 is 7.

so, we have,

Factor out 7 from the expression and remaining will be.

7(7x-1)

i.e. 49x - 7 = 7(7x-1)

Hence, Option C is correct. Factor using the GCF: 49x - 7 is 7(7x-1).

The length of a rectangle is increasing at a rate of 8 cm/s and its width is increasing at a rate of 6 cm/s. When the length is 7 cm and the width is 4 cm, how fast is the area of the rectangle increasing?

Answers

Given :

The length of a rectangle is increasing at a rate of 8 cm/s and its width is increasing at a rate of 6 cm/s. When the length is 7 cm and the width is 4 cm .

To find :-

how fast is the area of the rectangle increasing?

Solution :-

As we know that :-

A = lb

To find the rate :-

d(A)/dt = d(lb)/dt .

Differenciate :-

dA/dt = l (db/dt ) + b (dl/dt )

Substitute :-

dA/dt = 6*7 + 4* 8 dA/dt = 42 + 32 cm²/s dA/dt = 74 cm²/s

Let:

x = code for country A

This is important: "the codes are three consecutive integers" That means,

x is code for country A

(x+1) is code for country B

(x+2) is code for country C

whose sum is 81" means

x + (x+1) + (x+2) = 90

3x+3=90

=3x=90-3

=3x=87

=x=87/3

=x=29

So, the codes are=29,30,31

To check 29+30+31=90

13-22 Aquaculturists (people who farm marine resources, typically in semi-enclosed areas off the coast) have development methods of growing various invertebrates as food sources, such as clams, mussels, and oysters. Other widely consumed species, such as squid, have never been successfully grown in controlled marine environments, and so they remain wild caught. Why MARTHAS STORY As a young child in Sierra Leone, Martha was told that she looked like her mother, so she spent hours in front of the mirror, trying to see in her own features an image of the mother she lost as a toddler. Marthas father, a successful businessman, cared deeply for his daughter. He bought her new clothes every week and took her to school every morning. In 2000, when Martha was eight years old, members of a rebel group trying to overthrow the government attacked her village. As the sound of gunfire filled the neighborhood, Martha and her father stayed locked inside their house for over a week, waiting for the fighting to stop. When things quieted down, rebels occupied the village, and the situation was tense. Marthas father saw his business drop off, and he was forced to move to a town he thought would be safe from rebel attack. There, he was able to rebuild his business and send money and clothes to his daughter. With her father gone, Martha moved in with her grandmother, who made a living by selling vegetables in the market. Sometimes Martha had to help her and missed school as a result. Her life became even more difficult when her grandmother had a severe stroke, which left her unable to walk and almost unable to speak. Martha, by then 13 years old, found herself caring for her ill grandmother and had no news from her father. Though Martha was barely able to keep up with schoolwork, she managed to pass the National Primary School Examination, which allowed her to go on to high school. However, with her father gone and her grandmother no longer able to work, there was no money for the necessary school fees. Marthas hopes for continuing her education now depended on her father, and she anxiously waited to hear from him. One morning, she received devastating news: the rebels had murdered her father. The whole world stopped for me, says Martha. For the first time in my life I felt alone. I realized I was an orphan. Martha is now staying with her stepmother (a woman her father married before his death and who she refers to as aunty) and her stepmothers three children. To help her new family, Martha sells biscuits in the street market, but she longs to go back to school. Luckily, her stepmothers new husband has shown sympathy toward her and is willing to help. The Impact of Armed Conflict Sierra Leones civil war (from 19912002) affected over 10,000 children like Martha, causing separation from their families and exposing them to violence. Some were injured or killed by landmines. Others were forced to serve as child soldiers. Many more children missed out on schooling and were often unable to get health care during the conflict. 1. List at least three ways in which armed conflict has affected Marthas life. List the words or phrases from the text that helped you identify the answer. 2. Martha has many responsibilities. What are two of those responsibilities? What words or phrases from the text helped you answer this question? Do you have similar or different responsibilities as Martha at home? 3.
