Answers

Answer 1

Answer:

-17 =x

Step-by-step explanation:

144 = -12 (x + 5)

Divide each side by -12

144/-12 = -12 (x + 5)/-12

-12 = x+5

Subtract 5 from each side

-12-5 =x+5-5

-17 =x

Answers

Answer:

Step-by-step explanation:

complementary angles sum to 90°

Let angle 1 =  x

    angle 2 =  3x - 8

  3x - 8 + x = 90

             4x = 98

               x = 24.5°

3(24.5) - 8 = 65.5°

or

90 - 24.5 = 65.5°

A) About 32
B) About 35
C) About 40
D) About 25

Answers

Answer:

A) About 32

Step-by-step explanation:

4 1/4 • 7 9/17

The first one is rounded down as 1/4 < 1/2 and the second one rounded up as 9/17 > 1/2.

4 * 8 = 32

Correct choice is A

4 1/4=17/47 9/17=128/17

A principal of $2200 is invested at 6.25% interest, compounded annually. How much will the investment be worth after 13 years

Answers

Answer:

Let S = Sum after 13 years

So = amount invested

t = time in years

i = annual interest rate = .0325

The S = So(1+i)t = $2,200(1.0325)13 = $3,334.21

After 13 years, the investment will be worth approximately $4365.67. To calculate the future value of the investment after 13 years with annual compounding interest, we can use the formula for compound interest.

Future Value (FV) = Principal (P) * (1 + (Interest Rate (r) / 100))^Time (n)

Where:

P = Principal (initial investment)

r = Annual interest rate (as a decimal)

n = Number of years

Given:

Principal (P) = $2200

Annual interest rate (r) = 6.25% = 6.25/100 = 0.0625 (as a decimal)

Number of years (n) = 13

Now, let's calculate the future value:

FV = $2200 * (1 + 0.0625)^13

FV = $2200 * (1.0625)^13

FV ≈ $2200 * 1.984396861  (rounded to 9 decimal places)

FV ≈ $4365.672097  (rounded to 2 decimal places)

After 13 years, the investment will be worth approximately $4365.67.

Answers

Answer:

558

Step-by-step explanation:

The sum of the first n numbers is ½n(n + 1)

which is the left most number in each row number n

so finding the row containing 526

½n(n + 1) > 526

½n² + ½n > 526

n² + n > 1052

n² + n - 1052 > 0

n > (-1 + √(1² - 4(1)(-1052))) / 2(1)

n > 31.938

so 526 is almost to the end of the 32 row.

The end of that row is ½(32(33)) = 528

so 526 resides two spaces to the right of 528

The end of the row below it, row 33, is ½(33)(34) = 561

As each row is one number longer than the previous row, we count back

2 + 1 = 3 numbers from the end to find what is under 526

561 - 3 = 558

The container that holds the water for the football team is 2/3
full. After pouring out 3
gallons of water, it is 1/2
full. How many gallons can the container hold?

Answers

Answer:

18 gallons

Step-by-step explanation:

We'll find out how much of the total container was lost when pouring out by subtracting 2/3 from 1/2.

2/3 = 4/6

1/2 = 3/6

4/6 - 3/6 = 1/6

1/6 of the total amount the container could hold was lost when 3 gallons was poured out. This means that 1/6 of the container equals to 3 gallons. We can then simply multiply 3 by 6 to find the number of gallons of liquid the container can hold.

3 * 6 = 18 gallons

Checking my answer:

18 * 2/3 = 6 * 2 = 12

12 - 3 = 9

1/2 of 18 = 9

This means that our answer is correct.

Based on your equation, what was the car’s approximate initial velocity (at time=0)?

How to find the equation of linear regression?

To find the regression equation, also called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator. These points are given on a table or in a scatter plot in the problem.

For this problem, the input and the output are defined as follows:

Input: Time in seconds.Output: Velocity in m/s.

Hence the points are given by:

(2, 13.1), (4, 19.8), (6, 28.1), (8, 34.6).

Using these points and a calculator, the equation is:

v = 3.64s + 5.7

The intercept of 5.7 represents the initial velocity in m/s.

The purpose statement answers thequestion "What am I trying to find out by doing thisexperiment?"The three most common types of labs are:inquiry labs, in which you measure howchanging one variable affects another variablediscovery labs, in which you observe a scientificphenomenon, perhaps for the first time.forensic labs, in which you gather and analyzedata as evidence to build an argument inresponse to a question, as in a court case,All three types of labs give you an opportunity tolearn important scientific skills and concepts.QuestionAt its core, science is about inquiry, or the act ofasking questions and seeking answers. Most labsbegin as the result of a question, which is why theintroduction of your lab report should include aquestion. For example, suppose you notice that youseem to play basketball better at the court in onepark than in another. After conducting research, yourealize that one of the surfaces of the court at thepark is different from that of your driveway. As aresult, you might formulate the scientific question"What effect does the court surface have on theheight that the basketball bounces?" To answer thisquestion scientifically, you could perform severalexperiments and gather data,Hypothesis (or Prediction)A hypothesis is an initial answer to a question, apossible explanation or expectation based on priorknowledge or research. Before starting most lbs,you will formulate a hypothesis. It should be listed inthe introduction of your tab reportA good scientific hypothesis states conditions,expected results, and possible reasons for thoseresults, For example, you could respond to thebasketball question with a hypothesis like "If thecourt surface is smooth concreto, as the park'scourt is, then the basketball will bounce higher,because smooth surfaces have better contact withthe ball." Like this hypothesis, hypotheses are oftenstructured using the format "il then, becausewhich is described below.The "it' portion of the hypothesis describessomething that you will change in the experiment The "then" portion of the hypothesis describeswhat you think will happen as a result of thatchange The "because" portion of the hypothesisdescribes the ason why you think that changewill occurIn other laboratory activities you will be asked tomake a prediction.
