Answer:

1 7/20

Step-by-step explanation:

You want to add 3/4+3/5, but they need to have the same denominator. A common factor for 4 and 5 is twenty, so multiply 3/4 by 5/5 and 3/5 by 4/4. This will give you 15/20 + 12/20. You can add this to get 27/20, or 1 7/20 as a mixed number

Christian opened a savings account with $3250. His account will earn 5.2% simple interest.
How much money will be in his account after 6 years?

Answers

The total amount of money will be in his account after 6 years is $4264.

Given that, principal = $3250, rate of interest = 5.2% and time period = 6 years.

What is the simple interest?

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.

Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years.

Substitute P=$3250, R=5.2% and T=6 years in simple interest formula

That is, S.I. = (3250 × 5.2 × 6)/100

= $1014

Amount = Principal + Simple interest

= 3250 + 1014

= $4264

Therefore, the total amount of money will be in his account after 6 years is $4264.

You are helping your friend research hybrid cars. You learn that on a long- distance trip, the Chevrolet Volt traveled 571.95 miles on 12.3 gallons of gas. You also learn that the Toyota Prius traveled 753.48 miles on 15.6 gallons of gas. Determine which car got better gas mileage.

A Toyota Prius

B Chevrolet Volt

C The Two Hybrids Are Tied for the best mileage

D Not enough information to determine The answer

Answers

Answer: A) Toyota Prius

========================================================

Explanation:

To get the mileage per gallon, you divide the number of miles over the number of gallons.

For the Chevy Volt, the mileage is 571.95/12.3 = 46.5 miles per gallon (mpg)

For the Prius, the mpg rating is 753.48/15.6 = 48.3

So the Toyota gets the better mileage per gallon.

---------

If you're curious why we divide the numbers like that, consider this example

You drive 200 miles using 5 gallons of gas. We can form the ratio

200 miles : 5 gallons

To get the mpg rating, we need to know how many miles we can drive on 1 gallon of gas. So we divide both sides by 5

200/5 miles : 5/5 gallons

40 miles : 1 gallon

This hypothetical situation leads to 40 mpg

Solve the following equations
7(3x + 5) - x = 75

Answers

Answer:

x = 2

Step-by-step explanation:

7(3x + 5) - x = 75

1. Distributive property

multiply 7 by whatever is in the parenthesis

7*3x + 7*5 - x = 75

21x + 35 - x = 75

2. Combine like terms

21x - x = 20x

20x + 35 = 75

3. Subtract 35 on both sides

20x + 35 - 35 = 75 - 35

20x = 40

4. Divide both sides by 20 since u want to isolate the variable

20x/20 = 40/20

x = 2

And thats ur answer

Answer:

Negative numbers are most important especially in the field of physics and chemistry. They help us in real life geometry and in almost everything. The discovery of the number system has changed the human civilization to such a great extent, that, without it, we can't even think of architectures and the nature's law(by calculus).

Dominantly, zero is the most ever used number and is very important to express anything.

Without it, you couldn't have the digital world (simply, no computers, no phones, no machines and no A.I.).

A high school has 44 players on the football team. The summary of the players' weights is given in the box plot. Approximately, what is the percentage of players weighing greater than or equal to 213 pounds

Answers

Answer:

Step-by-step explanation:

The missing image is attached below.

From the given information

The number of players is 44.

From the box plot;

The minimum weight = 154 pounds

The first quartile Q₁ = 159 which is 25% of the data below 159 pounds.

The second quartile Q₂ = 213 which is 50% of the data below 213 pounds

The third quartile Q₃ = 253 which is 75% of the data below 253 pounds

The maximum weight = 268 pounds.

Here, the value of 213 is the middle value and which signifies the median.

The 50% of the data are located both on the left side and the right side of the median.

Thus, the percentage of players weighting greater than or equal to 213 pounds is 50%.

Use the discriminant to describe the roots of each equation. Then select the best description.

2 = x2 + 5x

double root
real and rational root
real and irrational root
imaginary root

Answers

ExplanationGiven the equation.

[tex]2 = {x}^{2} + 5x[/tex]

Arrange the expression into the standard form.

[tex]0 = {x}^{2} + 5x - 2 \\ {x}^{2} + 5x - 2 = 0[/tex]

Discriminant

From the standard form equation and from the given equation.

[tex]a {x}^{2} + bx + c = 0 \\ a = 1 \: \: \: b = 5 \: \: \: c = - 2[/tex]

Discriminant Formula

[tex]D = {b}^{2} - 4ac[/tex]

Substitute the value of terms in the discriminant formula.

[tex]D = {(5)}^{2} - 4(1)( - 2) \\ D = 25 - 4( - 2) \\ D = 25 + 8 \\ D = 33[/tex]

Discriminant Types

[tex]D > 0 \: \: \: \: 2 \: \: real \: \: roots \\ D = 0 \: \: \: \: 1 \: \: real \: \: root \\ D < 0 \: \: \: imaginary \: \: roots[/tex]

We can rule out the Imaginary root and double root because the discriminant is greater than 0. Therefore, the only choices are either Irrational or Rational.

However, we cannot factor the expression by using two brackets or common factor. We can say that the equation has two real irrational roots.

Answerreal and irrational root

x2+5x-2=0
a=1, b=5, c=-2

b2-4ac is the discriminant.
(5^2)-4(1)(-2)
25+8=33, so the discriminant is positive

This means there are two real rational roots, so the answer is the second option

A peep increased by 25% is a pop. A pop decreased by 40% is a slug, and a slug increased by 100% is a slap. What percent of a peep is a slap

Answers

Answer:

A slap is 120% of a peep

Step-by-step explanation:

We shall make use of values here

Let a peep be value of 100

A pop is 100 + 25% of 100

= 100 + 0.25(100) = 125

Pop = 125

A slug is pop deceased by 40%

= 125 - (40% of 125)

= 125-(50) = 75

A slap is a slug increased by 100%

= 75 + (100% of 75)

= 75 + 75 = 150

So now, we want to calculate percent of peep is a slap

That will be;

150/125 * 100%

= 120%
