Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points. What would be Mia's test score (out of 50) if she got 3 questions wrong? What would be her score if she got x questions wrong?

Answers

Answer:

Mia's test score is 44 if she got 3 questions wrong.

Mia's test score is (50-2x) if she got x questions wrong.

Step-by-step explanation:

It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.

If she got 3 questions wrong, then

Deducted marks [tex]=2\times 3=6[/tex]

Marks obtained by Mia = Total marks - Deducted marks

                                      [tex]=50-6[/tex]

                                     [tex]=44[/tex]

So, Mia's test score is 44 if she got 3 questions wrong.

If she got x questions wrong, then

Deducted marks [tex]=2\times x=2x[/tex]

Marks obtained by Mia = Total marks - Deducted marks

                                      [tex]=50-2x[/tex]

So, Mia's test score is (50-2x) if she got x questions wrong.

1. Conrad spent $48 on art supplies. The canvas for each of his paintings is an additional $2. He plans to sell his paintings for $10. a. Write an equation that could be used to find the number of paintings (p) he will need to sell to break even.

Thanks​

Answers

Equation: 48+2p=10p
Answer: P=6
Solution: 48+ 2p=10p
Subtract 2p from both sides. It will then make the equation 48=8p.
Divide both sides by 8 to get p alone. 48/8=6
P=6
:)

The equation for break even is 8P = 48

What is an Equation ?

An equation is an expression that states the equality of two things expressed in different form.

In the given question

Conard spent $48 for art supplies

Canvas costs $2

He plans to sell his painting for $10

Without the canvas his paintings costs $(10 - 2)

= $8

So, no. of paintings (P) to break even he needs to sell

8P = 48

P = 6

∴ Conard needs to sell 6 paintings to break even.

The population of Austin, Texas, was about 494,000 at the beginning of a decade. The population increased by 3% each year. Write an exponential growth model that represents the population y (in thousands) t years after the beginning of the decade. Find and interpret the y-value when t = 10.

Answers

Answer:

y(t) = 494 (1.03)^t

y(10) = 663,89

Step-by-step explanation:

An increase in population by 3% each year means that at the end of each year, the population is 1.03 times what it was at the start of the year

This increase in population continues for t years

Exponential growth model that represents the population y (in thousands) t years after the beginning of the decade is

y(t) = 494 (1.03)^t

Where,

y = population

t = number of years

Find y when t = 10

y(t) = 494 (1.03)^t

y(10) = 494 (1.03)^10

= 494 ( 1.3439)

= 663.8866

Approximately y(10) = 663.89

This means that after 10 years from when the population was 494,000, it increased to 663,89.

5.3x10 4 in standard form.

Answers

Answer:

5.3× 10⁴= ?

Step-by-step explanation:

10⁴ can also be written as 10×10×10×10= 10000

so, 5.3 × 10000= 53000

Scientific notations are the way through which a very small or a very large number can be written in shorthand. The value of 5.3×10⁴ in standard form is equal to 53,000.

What are Scientific notations?

Scientific notations is the way through which a very small or a very large number can be written in shorthand.  In scientific notations when a number between 1 and 10s is multiplied by a power of 10.

For example, 6,500,000,000,000 can be written as 6.5e+12.

Given the numerical value 5.3×10⁴ which is needed to be written in the standard form, therefore, we can write,

5.3 × 10⁴

= 5.3 × 10,000

= 53,000

Hence, the value of 5.3×10⁴ in standard form is equal to 53,000.

The change in kinetic energy (in joules) as a horse accelerates from canter to gallop is found using the expression 1/2 times 350 times (12 2 Minus 6 2

Answers

Answer:

[tex]\mathtt{\Delta K.E = 10500 \ J}[/tex]

Step-by-step explanation:

Given that:

the expression for the change in kinetic energy = [tex]\dfrac{1}{2} \times 350 \times ( 122 -62)[/tex]

Recall that

Kinetic energy K.E = [tex]\dfrac{1}{2}mv^2[/tex]

where,

m = mass of the horse

v = velocity of the horse

The change in kinetic energy between  two instant times can be expressed by the relation

[tex]\Delta K.E = K.E_2 - K.E_1[/tex]

[tex]\Delta K.E =\dfrac{1}{2}mv^2_2- \dfrac{1}{2}mv^2_1[/tex]

[tex]\Delta K.E =\dfrac{1}{2}m(v^2_2-v^2_1)[/tex]

where;

m = 350

Step-by-step explanation:

Step 1: Subtract x from both sides.

0.5x−0.5=3.25

Step 2: Add 0.5 to both sides.

0.5x−0.5+0.5=3.25+0.5

0.5x=3.75

Answers

Answer:

2 3/4 gallons in each container

Step-by-step explanation:

Gallons of water = 11

Containers = 4

Larry pours 11 gallons of water equally into 4 containers

Gallons of water in each container = Total gallons of water / number of containers

= 11 / 4

1/x = (x+3)/(2x^2), where x ≠ 0.

Cross-multiply to give 2x^2 = x(x+3).

2x^2 - x^2 - 3x = 0

x^2 - 3x = 0

x(x - 3) = 0

Answers

When 2 lines are parallel to each other mean than they have same gradient
y=5x +2
Gradient=5

Let the parallel equation be y=5x +c
Since this equation pass through (4,7), means that the point satisfy the parallel equation
7=5(4)+c

My project is super short, it won't take long to look over. Please tell me anything that I can do to improve my Spanish and anything I need to correct. Here are the rules for the project: Write one general sentence stating that the weather is good, bad, beautiful, etc. Write two specific types of weather, such as sunny, cloudy, cold, hot, mild, raining, snowing, foggy, drizzling, etc. Write the temperature. Description of the place: Using the Spanish you've studied so far, describe the appearance of the location by using the correct form of ser with descriptive adjectives. Use hay, meaning "there is" or "there are" to talk about things that are found there. This description should include at least three pieces of information about the location. Account of the day's events: Choose three activities per picture. All activities should be in the present tense, since the past tense hasn't been studied in detail. However, with teacher permission, the past tense charts in lesson 1 may be used to tell about specific activities that were done that day. Use of Spanish in the writing: Make sure that the verb endings match their subjects. Check that all irregular verbs are spelled correctly. Verify that the overall communication is clear and knowledge acquired from the program was clearly applied in your writing. Make sure that a variety of weather vocabulary is used and there isn't much repetition of the same weather conditions from one picture to the next. Pictures to include: Include a picture of each of the three locations you reference in your project. These pictures should represent the weather and places you describe in Spanish. Te toca a ti. It's time to get started! This project may be completed as a journal on paper, but can also be a slide show, or any other creative presentation you can think of. It's best to follow the simple steps below to work through it. Part 1: Your pictures are the main focus, so begin your project by choosing three pictures that show interesting things, and a variety of weather conditions. For instance, you can use pictures of a ski resort when it's snowing, an adventure park when its raining and the lines for the rides are very short, and a park or beach when the weather is sunny. Decide how you'd like to put your information together. Choose whether you'll create a journal, a slide show presentation, or some other way to bring your information together. Make notes on the weather, descriptions, and activities you plan to discuss in the project. Write your paragraphs in Spanish and have your teacher or a peer edit your work and give you suggestions for improvement if necessary. Create a rough draft of your journal with writing and pictures all in place. Edit your work, and make sure verbs are conjugated correctly, adjectives agree with the nouns they modify, and weather expressions are used correctly. Ask somebody who understands Spanish to edit your work again. Make any changes necessary and then check your work thoroughly for both content and appearance. If your teacher requires you to present the project, tell your classmates all about your vacation and have fun!
