55 miles per hour write a algebric expression to show how far the car will travel in a certain number of hours

Answers

Answer 1

55miles in an hour times x( # of hours that are unknown)

Answer 2

Final answer:

The algebraic expression for the scenario is 'd = 55t', where 55 (miles per hour) is the constant, and 't', which represents time in hours, is the variable. This expression is used to calculate the distance traveled by a car.

Explanation:

The subject of your question is algebra, particularly involving the concept of linear equations. In this scenario, you're looking to determine how far a car will travel given a certain speed and number of hours. Your constant in this case will be the speed of the car, which is 55 miles per hour. The variable is the time in hours, which we can denote by 't'. Hence, the algebraic expression representing this scenario would be d = 55t where 'd' represents the distance traveled by the car. The distance is calculated by multiplying the constant speed by the variable time.

The largest exponent in a polynomial is called its _____.

Answers

Answer:Degree of a polynomial :)

Final answer:

In mathematics, the largest exponent in a polynomial is referred to as the polynomial's degree. For example, in the polynomial 2x^3 - 5x^2 + 3x - 7, the degree would be 3 as it is the highest exponent.

Explanation:

The largest exponent in a polynomial is called its degree. To understand this concept, consider the polynomial 2x^3 - 5x^2 + 3x - 7. Each 'x' represents a term, and the highest numerical exponent of these terms is the degree of the polynomial. In this case, the polynomial's degree is 3, since that is the highest exponent in the equation.

Rhonda deposited $4,227.29 into a savings account with an interest rate of 4.9% compounded monthly. About how long will it take for the account to be worth $9,000?

Answers

Final answer:

To find how long it will take for $4,227.29 to grow to $9,000 with a 4.9% interest rate compounded monthly, we use the compound interest formula rearranged to solve for time. The calculation involves using the natural logarithm to find the number of years required for the investment to reach the target amount.

Explanation:

The question pertains to determining how long it will take for a sum of money, specifically $4,227.29 deposited into a savings account with a 4.9% interest rate compounded monthly, to grow to be worth $9,000. We can use the formula for compound interest to solve for the time period required for the investment to reach the desired amount. This formula is A = P(1 + r/n)^(nt), where A is the amount of money accumulated after n years, including interest, P is the principal amount (the initial sum of money), r is the annual interest rate (decimal), n is the number of times that interest is compounded per year, and t is the time the money is invested for in years.

To find the time (t), we rearrange the formula: t = [log(A/P)] / [n*log(1 + r/n)]

Calculate the monthly interest rate r/n: 0.049/12Substitute the values into the formula:P = $4,227.29A = $9,000r = 0.049n = 12Use a calculator to compute the time t.

The calculation will provide the time in years, which can be multiplied by 12 to convert it to months, in case the answer is needed in months.

The length of the base of an isosceles triangle is 2cm less than twice the length of any of its equal sides. If its perimeter is 98cm, what is its area?

Answers

Alright, so if the length of one of the equal sides are x, 2x-2 is the base and x+x+2x-2=98=4x-2. Adding 2 to both sides, we get 100=4x and dividing by 4 we get 25 as one of the equal sides and 48 as the base. Since we need to find the height to find the area, we can draw a line straight down the middle to form 2 right triangles, with the hypotenuse being 25 and the base being 48/2=24. Therefore, since a^2+b^2=c^2 and 24^2+b^2=25^2, we have

25^2-24^2=49=b^2. Square rooting both sides, we get b=7=height, and the base*height/2 is the area, so we get 48*7/2=168 as the area

A store makes a 20 ounce cup of coffee that is 70% and 30% steamed milk. How many ounces of milk is used in a 20 ounce cup of coffee?

Answers

30% of 20 is equal to 6 so your answer would be 6.

Final answer:

To find how many ounces of milk are used in a 20 ounce cup of coffee that is 70% coffee and 30% steamed milk, set up a proportion and solve for x. The result is 14 ounces of milk.

Explanation:

To find how many ounces of milk are used in a 20 ounce cup of coffee that is 70% coffee and 30% steamed milk, we can set up a proportion. Let x represent the number of ounces of milk. Since the cup of coffee is 70% coffee, the rest (30%) is milk. This can be written as:

70/100 = x/20

Cross multiplying, we have:

70 * 20 = x * 100

Simplifying, we get:

1400 = 100x

Dividing both sides by 100, we find:

x = 14

Therefore, 14 ounces of milk are used in a 20 ounce cup of coffee.

So basically, so start off, let's explain the term "absolute value".
When you want to find the absolute value of something, such as the number 3 in this question, you just look at the number you have.
In this case, you have the number 3, and you want to find two numbers that have an absolute value of 3.
Absolute value is basically always a positive number that's the same number as you had.
You're looking for 3, and there are two numbers with an absolute value of 3.
The numbers are both -3 and 3 since the absolute value guarantees us that the number (or negative number) is always a positive.
Another example: You want to find the absolute value of 113.
The two numbers that have an absolute value of 113 is -113 and 113. Absolute value guarantees the number is always positive, thus you have your two numbers.

What is 0.26 written as a fraction in simplest form??

Answers

13/50 is the simplest form

Hope this helps :)

The simplified fraction of 0.26 is 13/50.

What is Fraction?

Every fraction has a numerator and a denominator separated by a horizontal bar known as the fractional bar.

The denominator represents the number of components into which the whole has been subdivided. It is positioned below the fractional bar in the lower section of the fraction.The numerator specifies how many fractional parts are depicted or selected. It is positioned above the fractional bar in the upper section of the fraction.

Now, we can remove the decimal and put the number of zeroes in the denominator.

So, 0.26

= 26/100

Now, simplifying the fraction as

= 13/ 50

Thus, the simplified fraction is 13/50.

Answers

Hey! Hope that I can help.

To do this, we need to notice the words being used. "More than" means adding on to the quotient of 63 and 9. "Quotient" means to divide 63 by 9 in this problem. Putting this into an expression gives us our answer.

Answer: A) 12 + 63 ÷ 9

The expression which shows 12 more than the quotient of 63 and 9 is option A) 12 + (63 ÷ 9).

We have to find the expression which shows 12 more than the quotient of 63 and 9.

For that, first find the quotient of 63 and 9.

Divide 63 by 9.

63/9 = 7

12 more than the quotient of 63 and 9 = 7 + 12 = 19

So the result is 19.

Now, we have to mathematically write the given word sentence.

12 is added to the quotient of 63 and 9.

12 is added to (63 ÷ 9)

Which of the following numbers are perfect squares?

121

Answers

36, 81, and 121 are all perfect squares

answer: 36, 81, and 121.

explanation: find out which numbers are perfect squares.

well, we know from our basic multiplication tables that: 6x6 = 36, 9 x 9 = 81 and 11 x 11 = 121.

what about 27 and 108?

we can rule out these numbers by finding square roots both bigger and smaller.

we know that 5 x5 = 25, so the square root of 25 is 5
we know that 6 x 6 = 36, so the square root of 36 is 6.

Perfect squares are whole numbers, and the square root of 27 is in between 2 other perfect squares, meaning it cannot be a perfect square.

we know that 10 x 10 = 100, so the square root of 100 is 10
we know that 11 x 11 = 121, so the square root of 121 is 11

Perfect squares are whole numbers, and the square root of 121 is in between 2 otehr perfect squares, meaning it cannot be a perfect square.

so, the only ones we can do are 36, 81, and 121. Hope this helps!
