Beth Ann practiced piano for 1 hour 5 minutes each day for 1 week. She had 5 songs to practice and spent the same amount of time practicing each song. How long did she practice each song during the week?

Answer:

side length of 2

side length of 6

side length of 7

Step-by-step explanation:

So remember the two shorter lengths added together have to be greater than the longest side length

For the first answer choice we add 7 and 8

7+8=15

The two shorter sides added are not greater then the longest side so that is not the answer

For the second answer choice we add

8 and 5

8+5=13

13 is not greater than 14 so this is not the answer choice either

For the third one we add 6 and 3

6+3=9 which is not greater than 10 so this is not the answer

For the last one we add 2 and 6

2+6=8 which is greater than 7 so this one is the answer

Answer:

D.

Step-by-step explanation:

D because 2 has a x next to it so you divide by 2 on both sides

Step-by-step explanation:

Area = (2x+5)( 3x+12) square units

= 6x² + 39x + 60 square units

Trinomial

Okay so first you want to simplify the given equation  (7x+3y)(7x-3y)

in order to do this you multiply the first number of the first equation (7x) with the first number of the second equation (7x) this gives you 49x^2

Now you want to multiply the second number of the first equation (3y) by the second number of the second equation (-3y) this gives you -9y^2

Its as easy as pie!

Answer:

The equation you would use is лr² (pi times radius squared).

Answer:

RQ = 10

Step-by-step explanation:

When two triangles are similar, the ratio of their corresponding sides are equal;

Thus, we have it that;

QP/RQ = BC/AB

12/RQ = 36/30

RQ = 12 * 30/36 = 10

Answer:

9:15 or 3:5

Step-by-step explanation:

A ratio can compare a part of a whole to a whole.

In this case, our whole is the total number of shots attempted: 15.

The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.

Put these values in a ration.

part:whole

9:15

Notice that 9 and 15 can be simplified by dividing both numbers by 3.

3:5

This is your simplified ratio.

The required equation of green and blue line is y = 3x- 4 and y = x+1

The standard equation of a line is expressed as y = mx + b

where;

m is the slope

b is the y-intercept

Note that the y-intercept is the point where the line cuts the y-axis

From the graph, the y-intercept of the green line is 3 while that of the blue is 1. This shows that the required equation of green and blue line is y = 3x- 4 and y = x+1

Step-by-step explanation:

Joey's current grade can be determined by weighting his scores with the weights given and adding the results

Tests = 0.6 x 82 = 49.2

Quizzes = 0.25 x 77 = 19.25

homework = 0.15 x 98 = 14.7

Answer: 1.5 x 10^5

Step-by-step explanation:

The first step is to re-arrange the factors like this :

5 x 3 x 10^2 x 10^2

Since

5 x 3 = 15

and the index law

10^a x 10^b = 10^a + ^b

gives us

10^2 x 10^2 = 10^2 + ^2 = 10^4

then we can rewrite the product like this :

5 x 3 x 10^2 x 10^2 = 15 x 10^4

Finally, we need to convert this into scientific notation :

15 x 10^4 = 1.5 x 10^5  

So the final answer is

1.5 x 10^5

Answer:

60 kilograms of the 30% solution

140 kilograms of the 40% solution

Step-by-step explanation:

Let x = the no. of kilos containing 30% salt (solution 1)

and 200 - x = the no. of kilos containging 40% salt solution 2)

.30x = amount of salt in solution 1

.40(200 - x) = amount of salt in solution 2

.37(200) = amount of salt in the final mixture

salt in solution 1 + salt in solution 2 = salt in final mix.

.30x + .40(200 - x) = .37(200)  

Let's multiply thru the equation by 100 to remove the decimal fractions

30x + 40(200 - x) = 37(200)

30x + 8000 - 40x = 7400

-10x = -600

x = 60 kilograms of the 30% solution

200 - 60 = 140 kilograms of the 40% solution

The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6 thus options (A) and (B) are correct.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.

As per the given equation,

3x² - 3x + 1

To find the roots of the above quadratic equation,

3x² - 3x + 1 = 0

x = [-(-3) ± √((-3)² - 4×3×1)]/(2×3)

x = [3 ± √(-3)]/6

x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6

Hence "The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6".
